Abstract

A movable mold is movable toward and away from a fixed mold so as to close and open the mold. The fixed mold includes an intermediate plate facing a movable-side mold plate. This intermediate plate has a retainer-molding recess which cooperates with the movable-side mold plate to form a retainer-molding cavity, and a core pin, which cooperates with a housing-molding recess to form a housing-molding cavity, is mounted on the intermediate plate. A retainer, molded in the molding cavity, is moved downward by an ejector pin into a position where the retainer is disposed coaxial with a housing. Then, the two molds are again closed together, so that the housing and the retainer are connected together, and then this assembled product is taken out.

Description

Make the method and the mould of resin formed article
The present invention relates to make the method and the mould of connector, in particular, relate to a kind of front side of connector shell or method that rear side is equipped with the connector of a retainer of being manufactured on.
The connector of so-called " preceding maintenance type " and " back keeps type " (seeing Fig. 6 and 7) is known.At first simply introduce the preceding maintenance type connector among Fig. 6.In connector shell 3, form the cavity 31 that holds metal terminal 30 respectively, in cavity 31, formed the lance 32 that contacts with metal terminal 30 again.Lance 32 is cantilevered, therefore, and can strain.When metal terminal 30 has just inserted in the cavity, strain or bending take place earlier in lance 32, enter in the gradient cavity that on the cavity lower surface, forms, then, when metal terminal 30 further was inserted into the precalculated position, lance 32 just kept the engagement (initial hold mode) with metal terminal 30.
Adorned a retainer 4 that prevents that metal terminal 30 from withdrawing in the front portion of connector shell 3.Outstanding maintainance block 34 can be inserted as respectively in the gradient cavity of corresponding lance 32 usefulness from the retainer 4.When retainer 4 was contained on the housing 3, each piece maintainance block 34 all contacted with the bottom surface generating plane of the lance 32 of collaborative work, so just can prevent reliably that metal terminal 30 from withdrawing (secondary hold mode).
Though not expression in detail among the figure, retainer 4 can be fixed on two positions, that is, and temporarily holding position (on this position, the degree of depth of retainer 4 insertion housings 3 is very shallow) and holding position (on this position, the degree of depth of insertion is very dark) fully.When retainer is on temporary transient holding position, also allow lance 32 bendings, so can allow metal terminal 30 insert.When retainer during in complete holding position, as mentioned above, the bending of lance 32 is restricted, and withdraws so can prevent metal terminal 30.
On the other hand, in back maintenance type connector shown in Figure 7, formed several cavitys 40 in connector shell, several metal terminals 42 can insert respectively in these cavitys.The same with the connector of preceding maintenance type, retainer can and move with respect to connector shell between the holding position fully in temporary transient holding position after one.When the back retainer was on temporary transient holding position, a terminal that forms in each cavity kept the pawl 43 on the preliminary metal terminal 42 with collaborative work of pawl 44 to mesh.When back retainer when moving on the complete holding position, the marginal portion 41 of back retainer under the secondary hold mode respectively with the back end in contact of metal terminal 42, can not withdraw thereby metal terminal 42 is remained on this position.
When making above-mentioned no matter that a kind of connector, above-mentioned housing 3 and retainer 4 are to use the independent zero machine that is molded as to be molded as respectively, then these parts that are molded as are delivered to the assembly shop, and various parts are fitted together, and become connector.This assembly process both can carry out with an automation that feed appliance is housed, and also can use manually-operated.
But, in above-mentioned common technology, housing 3 and retainer 4 molded, and all be the assembly process that they link together separately to implement, needing through the mold pressing work step, transportation work step and assembling work step just can be made finished product.In addition, after operating personnel assemble part, also need the detection work step.Like this, make finished product just needs a lot of work steps, and this has just improved manufacturing cost.Moreover, also must manage the mould of housing 3 and the mould of retainer 4, therefore, the expense of management has also increased.
The present invention puts forward in view of these problems of the prior art.An object of the present invention is to provide a kind of method of making connector with low cost.
In order to achieve the above object, the invention provides the method and the metal die of the resin moulded products that a kind of manufacturing is assembled into by two resin parts at least, this method is come out many resin parts of working in coordination with the pair of metal mould is molded, this a pair of mould can move along axis direction, adjacent to each other or leave, make these resin parts move to the face of facing one another, a part in these resin parts moves to the position near another resin part, so that these resin parts are assembled together under predetermined state.
In the present invention, when two moulds are closed together, between these two moulds, many die cavitys have been formed.The resin of fusion is full of die cavity, just can be molded into these resin parts.After the hardening of resin, mould is opened, so, on these two moulds, just stayed the moulded resin part that is assembled together.In mould, move the resin part that is molded as with travel mechanism then, so these parts just face one another along common axis.Then, at least one resin part is moved towards another resin part, so these two resin parts just are assembled together under predetermined state by means of assemble mechanism.
According to the present invention, these work steps in order, that is, the molded and assembly processes these resin parts that are molded as of these many resin parts are finished in mould, and therefore, the cost of this resin moulded products is very low, because technical process has shortened.In addition, under the state that mould is opened, as long as operate assemble mechanism a little, just can be assembled together these resin parts, therefore, with one of employing the operation of mould closure is compared the situation that the resin part is assembled together, the needed time of this operation has shortened, and energy needed is also less.

Below with reference to Fig. 1 to 7 first preferred embodiment of the present invention is described.Though this embodiment is at keeping the type connector before above said,, the present invention also can be applicable to the back and keeps the type connector.A mould that is used for finishing the inventive method is contained in an injection molded equipment, and its pith will be described below, but Fig. 1 to Fig. 5 simplified for ease of explanation, and this mould is strictly not corresponding with the connector shown in Fig. 6.
The mould of present embodiment comprises a mobile mould and a fixed die, and above-mentioned mobile side form S comprises a mobile side template 2 that is fixed on the mobile side decking 1.On the mold pressing surface of mobile side template 2, made the housing molded indentation 5 that is used to form connector shell 3, on this mold pressing surface, below above-mentioned housing molded indentation 5, also formed the unloading hole 6 of core rod 7 in the middle of being used to hold, the axis in groove 5 and unloading hole 6 is positioned on the common vertical plane (plane of drawing).Mobile side decking 1 is connected with a driving mechanism (not shown), and can move a predetermined stroke along the left and right directions among the figure.
Fixed die M comprises that one is contained in the fixed bolster plate 10 on the fixation side decking 8 by installing plate 9 and is installed in middle core rod 7 on the intermediate plate 11.
Said fixing side template 10 is installed in installing plate 9 on a side or surface of mobile mould.Formed a retainer molded indentation 13 at this fixed bolster plate 10 on the surface of mobile mould, this groove 13 is arranged on the horizontal direction of figure and housing molded indentation 5 coaxial lines.
Above-mentioned intermediate plate 11 is installed on the fixation side decking 8, and is arranged between fixed bolster plate 10 and the moving die plate 2.Be provided with a spring 12 between installing plate 9 and intermediate plate 11, this spring forces intermediate plate to leave installing plate 9.On intermediate plate 11 and that part that fixed bolster plate 10 is aimed at, form the unloading window 14 of a break-through, and this unloading window 14 is arranged to and housing molded indentation 5 and retainer molded indentation 13 coaxial lines.Intermediate plate 11 can move to (among the figure) left and right directions, and fixed bolster plate 10 then closely matches with unloading window 14, and therefore, intermediate plate can move to installing plate 9 and closely contact.
Middle core rod 7 is arranged on intermediate plate 11 on the surface of mobile side form.Middle core rod 7 under normal circumstances is in the position of aiming at unloading window 14, and its distal portions is relative with fixed bolster plate 10 with mobile side template 2 respectively with proximal part.Middle core rod 7 towards template 2 the surface on form a core rod molding part 7A, it cooperates with molded indentation 5 on the template 2 and forms a die cavity, is used for molded shell 3 when closed together with convenient two mould S and M.Formed a core rod molding part 7B at middle core rod on the surface of template 10, the molded indentation 13 on it and the template 10 cooperates and forms a die cavity, is used for molded retainer 4 when closed together with two mould S of box lunch and M.As mentioned above, middle core rod 7 is arranged to usually and unloads window 14 and aim at.Middle core rod 7 is connected with the mechanism that reciprocatingly slides, so it can be aimed in the unloading hole 6 that is moved down on the drawing with on the mobile mould before housing 3 and retainer 4 are linked together.When housing and retainer linked together, middle core rod 7 just inserted in the unloading hole 6, so it can not hinder mobile mould.
After mould was opened, when retainer 4 that has been molded as and housing 3 were also stayed in molded indentation 5 and 13 respectively, the surface that those of retainer that has been molded as and housing will link together all was exposed on the position relative to each other.The gate (not shown) of leading to two molded indentations respectively is opened, and goes so the resin of fusion just is filled in these molded indentations by corresponding gate.
The process of molded and assembling shell 3 of the mould that utilizes above-mentioned structure and retainer 4 is described below.
Under the state that mould shown in Figure 1 is opened, when mobile mould when fixed die moves, above-mentioned mobile side template 2 at first is close to intermediate plate 11, then the core rod molding part 7A of middle core rod 7 just insert in the housing molded indentation 5, thereby between the two, form the molding cavity of housing.When mobile side form S further moved forward, above-mentioned intermediate plate 11 was return, and made the spring 12 that contracts simultaneously.Then, when intermediate plate 11 and installing plate 9 were combined closely, said fixing side template 10 entered in the unloading window 14, so the core rod molding part 7B of middle core rod 7 and retainer mold pressing groove 13 are worked in coordination, between forms the die cavity of retainer.
After the mould closure was good, the resin of fusion just charged into the housing die cavity that forms between middle core rod 7 and template 2, and the retainer die cavity (referring to Fig. 2) that forms between middle core rod 7 and template 10.Then, when resin through one section preset time and after solidifying, above-mentioned mobile mould returns, mould is opened.As a result, core rod 7 is recalled from housing molded indentation 5 in the middle of making, and under the influence of spring 12, intermediate plate 11 separates with installing plate 9, and said fixing side template 2 is just withdrawn from from unloading window 14.At this moment, housing 3 still remains in the housing mold pressing groove 5, and retainer 4 is still stayed in the retainer molded indentation 13.
Then, reciprocatingly slide mechanism's (not shown) make in the middle of core rod 7 move to the position of aiming at the unloading hole 6 in the mobile mould (that is, the imaginary line position from Fig. 3 moves to the solid line position among Fig. 3).As a result, the left and right directions of unloading window has all been opened, so housing 3 that is molded as and retainer 4 just are exposed to relative to each other and are on the position of coaxial line.
Then, mobile mould S moves to the left of figure again, and intermediate plate 11 is got back to and installing plate 9 tight position contacting.At this moment, middle core rod 7 inserts in the unloading hole 6 of mobile mould.Meanwhile, fixed bolster plate 10 enters again in the unloading window 14 of intermediate plate 11, and closely contacts with mobile side template 2.As a result, retainer 4 just links together with the front part of housing 3 under the temporary transient state that keeps.
Then, when mobile mould leaves after above-mentioned operation again, the connector that housing 3 and retainer 4 have linked together is just stayed in the housing molded indentation 5, then, this connector is ejected it by a knock pin (not shown) with die sinking consistent action of operation (perhaps self contained function) from mould.Fig. 5 represents the state of the die sinking course of work.After this, middle core rod 7 is got back to its home position (as shown in Figure 1), for next mold pressing procedure is got ready.
As mentioned above, in the present embodiment, the work step of molded shell 3 and retainer 4, and can carry out the assembling work step that they link together simultaneously, therefore, just do not needed conveying in the conventional method and assembly process, and, also shortened from being dosed into the time of finishing product, and the cost of making has also reduced because of the shortening of technical process.In addition, because can be different types of mechanograph, i.e. housing 3 and retainer 4, molded come out from the management of mould, also is very favourable in same mould.

Before the fairlead 114 that holds two leads 106 under the mould closure state respectively is embedded in respectively on the end of mobile side template 113, and parallel with axis.Though not expression clearly, is that the lead and the fairlead of the motion guide of two mobile side templates 113 and 140 is arranged between two templates 113 and 140 among the figure.Above-mentioned housing molded indentation 115 forms on the surface of middle core rod 133 at preceding mobile side template 113.This housing molded indentation 115 and said fixing side retainer molded indentation 108 coaxial lines, and also with middle core rod 133 coaxial lines that are positioned on the mold position.Open the gate (not shown) of leading to housing molded indentation 115 and fixation side retainer molded indentation 108, the resin of fusion just charges in these two molded indentations by corresponding gate.
In mobile mould 102, between mobile side template 140 in back and mobile side installing plate 112, be provided with a pin plate 129.This pin plate 129 is connected (not shown) with a driving mechanism, can move along the fore-and-aft direction that parallels to the axis.
The core pin 119 of imbedding that is used for molded shell 170 is installed in the mobile side template 140 in back, and parallel with axis, this far-end of imbedding core pin 119 cooperates with preceding mobile side template 113, can slide.When molded shell 170, the above-mentioned core pin 119 of imbedding protrudes in the housing molded indentation 115, keep step 182 etc. so that be molded into, but, after mould is opened, before retainer 171 and housing 170 link together, it is separated from each other to move forward and backward side template 113 and 140, as shown in figure 11, so the above-mentioned core pin 119 of imbedding is just withdrawn from from the housing 170 that is molded as from housing molded indentation 115.
Be used for that the connector that housing 170 and retainer 171 link together is ejected the knock pin 120 that comes and be installed in pin plate 129, extend along the direction parallel with axis.The far-end of this knock pin 120 is arranged to flush with the inner surface of housing molded indentation 115 basically usually.But after retainer 171 and housing 170 linked together, when pin plate 129 left mobile mould 102 and travels forward separately, above-mentioned knock pin 120 just inserted in the housing molded indentation 115, and connector is ejected from groove.
The technical process of the mould molded shell 170 that adopts present embodiment and retainer 171 is described below and the two assembling work step that couples together.
Under the mould closure state in Fig. 9, preceding mobile side template 113 keeps closely contacting with fixed bolster plate 105, above-mentioned housing molded indentation 115 is by 133 closures of middle core rod, formed the space of a closure, and a main core pin 107 and the above-mentioned core pin 119 of imbedding are all inserted in the housing molded indentation 115, thereby have formed a die cavity that is used for molded shell 170.
Opposite side at middle core rod 133, the retainer molded indentation 135 of core side combines with the retainer mold pressing groove 108 of fixation side, form the space of a closure, core pin 109 is then inserted in this closed space, thereby has formed the die cavity of molded retainer 171.
Under this mould closure state, the resin of fusion charges into by the gate (not shown) in the die cavity of the die cavity of molded shell and molded retainer (referring to Figure 10).Then, when through one section preset time, after the hardening of resin, mobile mould is return, and mould is opened.As a result, retainer 171 is still stayed in the fixation side retainer mold pressing groove 108, and housing 170 is then stayed in the housing molded indentation 115 in the mobile side form, and as shown in figure 11, retainer 171 and housing 170 are separated from each other.When mould was opened, middle core rod 133 left fixed bolster plate 105 under the effect of spring 121, so the retainer 171 that is molded as just drops out from the core side retainer molded indentation 135 of middle core rod 133.Meanwhile, preceding mobile side template 113 leaves the mobile side template 140 in back under the effect of spring 134, just withdraw from from the housing 170 that is molded as so imbed core pin 119.
Then, start the slide mechanism (not shown), core rod 133 moves to the position (referring to Figure 12) of returning in the middle of making.As a result, this member (middle core rod 133) that obstruction is arranged is just no longer between retainer 171 that is molded as and housing 170, so these two parts that are molded as are in mutually on the relative position of coaxial line.Then, when the driving mechanism (not shown) moved forward reclaiming plate 110, the knock pin 111 that its far-end contacts with retainer 171 promoted retainer 171, makes it withdraw from from fixation side retainer molded indentation 108.Then, above-mentioned retainer 171 is packed in the cover part 173 of housing 170.When retainer 171 is pushed forward, core pin 109 is also withdrawn from from the retainer 171 that is molded as, imbedding core pin 119 has then withdrawn from from the housing 170 that is molded as, therefore, when retainer 171 is connected with housing 170, temporarily keep pawl 183 and the engagement that keeps step 182 just can not be affected fully.So under this temporary transient holding position, retainer 171 connects with housing 170.After finishing above-mentioned assembly process, reclaiming plate 110 is got back to its home position (referring to Figure 13).
Then, when driving mechanism (not shown) promotion pin plate 129 marched forward, knock pin 120 ejected connector to come from housing molded indentation 115, make its depanning.After taking out connector, pin plate 129 and middle core rod 133 are just got back on their corresponding home positions, make mould be ready for next molding process.
As mentioned above, in the present embodiment, the work step of molded shell 170 and retainer 171, and can carry out the assembling work step that they link together at the same time, therefore, just do not needed conveying in the conventional method and assembly process, and, also shortened from being dosed into the time of making product, and the cost of making has also reduced because of the shortening of technical process.
In the present embodiment, just can link together housing 170 and retainer 171 as long as handle pushing pin 111, and just can eject connector come as long as handle knock pin 120.It is also contemplated that and utilize the closed operation of comprehensive mould to realize above-mentioned assembling and eject operation.But in this case, that part that move is very big, so the energy that needs is also many.On the other hand, in the present embodiment, the part that move is minimum, and is simple in structure, and this operation energy needed is also few.
Different mechanographs, promptly housing 170 and retainer 171 can be shaped in a mould, and from the angle of mold management, this also is very favourable.In the present embodiment, the core pin 119 and 109 of molded usefulness had all been withdrawn from respectively from housing 170 and retainer 171 before implementing assembly process, and therefore also having can be these two advantage that part successfully links together.
Can carry out various improvement to the present invention, so following modification falls within the scope of the present invention:
Though in first embodiment, be moving closure and opening unloading window 14 with middle core rod 7, but also can be with such structure, promptly, leave the space between middle core rod 7 and the unloading window 14, and allow whole intermediate plate 11 move between the two positions, and one is middle core rod 7 and two positions that template is aimed at, another is the position of middle core rod and unloading window 14 alignings.
In first embodiment, the assembly process that the retainer that is molded as 4 and the housing 3 that is molded as are linked together rely on mould again closing course realize.But, also can adopt down array structure to realize.For example, a discharging pin (not shown) is set in moving die plate 2.Finished according to Fig. 3 molded after, drive the discharging pin, the housing 3 that is molded as is pushed to retainer 4, thereby retainer and housing is linked together.The connector that is assembled in this way falls down from mould owing to the weight of itself breaks away from housing molded indentation (also a backing-out punch can be set for this reason).
Though in a second embodiment, what describe is the structure that the housing of connector and retainer are linked together, but the present invention also can be used for other various resin formed articles, and the quantity of mechanograph is not limited to two, can also be applied to the structure that plural part is linked together.

In addition, according to the present invention, when the housing of connector and retainer were shaped, the resin that can charge into different materials or different colours to the housing molding mould and the retainer finishing die of connector was made the housing and the retainer of the connector of different materials or different colours.
The 3rd embodiment
Below with reference to Fig. 1-2 0 the 3rd preferred embodiment of the present invention is described.Though present embodiment is at keeping the type connector before above-described, the present invention also can be used for the back and keep the type connector.One pith wherein is explanation below all for the mould of finishing the inventive method is contained in the injection moulding molding apparatus, and still, for convenience of explanation, Figure 16 to 20 has been simplified, and this mould is not strictly corresponding with the connector among Fig. 6.
The mould of present embodiment comprises a mobile mould and a fixed die, and this moves mould S and comprises a mobile side template 202 that is fixed on the template 201.On the molded surface of mobile side template 202, formed a housing molded indentation 205 that is used for housing 3 shapings of connector, and on this mold pressing surface, formed the receiving portion 206A of a mold pressing retainer in the drawings on the position of vertical direction and housing molded indentation 205 partition distance.
Fixed die M comprises a receiver sheet 208, and this piece plate is arranged to and mobile mould S coaxial line usually, and is fixedly mounted on the installing plate 207, and also is provided with a fixed bolster plate 209 in the place ahead of receiver sheet 208.
Be provided with spring 210 between fixed bolster plate 209 and receiver sheet 208, this spring forces fixed bolster plate 209 to leave receiver sheet 208.Though not expression also is provided with stop assembly among the figure between fixed bolster plate 209 and receiver sheet 208, surpass a predetermined numerical value so that prevent the distance between this two boards.The proximal part of the core pin 211 of molded retainer just is installed on the receiver sheet 208, and the distal portions of the core pin 21 of molded retainer then inserts among the pin hole 211A that flatly forms in fixed bolster plate 209, and can slide.This pin hole 211A ins succession the front one and to form on fixed bolster plate 209, with the retainer molded indentation 206B of the receiving portion 206A coaxial line of molded retainer.The far-end of the core pin 211 of molded retainer, (promptly under normal circumstances, under the mould open mode as shown in figure 16), be to leave retainer molded indentation 206B's backward, but under mould closure state (Figure 17), the termination of this far-end flushes with the inner surface of retainer molded indentation 206B, therefore, retainer molded indentation 206B and retainer receiving portion 206A have formed the die cavity of a molded retainer jointly.
The approaching part of the core pin 212 of molded shell is installed on the receiver sheet 208, and is parallel with the core pin 211 of molded retainer, and aims at it in vertical direction.The far-end of the core pin 212 of molded shell is passed in the through hole 212A that the horizontal direction of fixed bolster plate 209 upper edge drawings forms, can slide therein, and, this root core pin 212 usually with mobile side template 202 on housing molded indentation 205 coaxial lines.When mould was closed, the far-end of core pin 212 inserted in the housing molded indentation 205, with the common die cavity that forms a molded shell 3 of this molded indentation.
When mould is opened, when molded good retainer 4 and housing 3 are stayed in molded indentation 206B and 205 respectively, just come out in the molded good retainer and the surface that will link together of housing, and relative to each other.The gate (not shown) of leading to two molded indentations 205 and 206 is respectively opened, and the resin of fusion charges in these two molded indentations 205 and 206 by corresponding gate.Mobile mould S in the said structure is connected with a driving mechanism (not shown), move back and forth about can be between the two positions, one is mold closed position, fixed bolster plate 209 closely contacts with moving die plate 202 on this position, one is mold opened position (Figure 16), these two templates 202 and 209 spaced-apart predetermined distances on this position.Mobile mould S also is connected (but can be connected on the common drive source) with a driving mechanism that is independent of above-mentioned driving mechanism, and can move by the above-below direction along drawing when the position that above-mentioned mould is opened.Therefore, mobile mould S can be reciprocating on two positions, and one is the position of molded shell 3 and retainer 4, and one is the rigging position that molded good retainer 4 and housing 3 are aligned with each other.
The mould molded shell 3 of employing said structure and the method for moulding and the assembling process of retainer 4 are described below.
When whole mobile mould S from die sinking position (Figure 16) when fixed die moves, at first be that moving die plate 202 is pressed on the fixed bolster plate 209.As a result, the far-end of the core pin 212 of molded shell inserts in the housing mold pressing groove 205.Then, when mobile mould S continued to move forward, fixed bolster plate 209 compression springs 210 contacted with receiver sheet 208, so these two moulds are just closed together.At this moment, the core pin 211 of molded retainer and the core pin 212 of molded shell all are on their corresponding normal positions, therefore, the receiving portion 206A of molded retainer and retainer molded indentation 206B have formed the die cavity of molded retainer 4, and housing molded indentation 205 has then formed the die cavity of molded shell 3.Then, the resin of fusion is charged in these two die cavitys.
Then, through one section preset time, after hardening of resin, mobile mould is got back to the position that mould is opened, so under the effect of spring 210, fixed bolster plate 209 leaves receiver sheet 208.At this moment, retainer 4 is stayed in the retainer molded indentation 206B, and core pin 211 is then return from retainer 4.Though retainer of representing among the figure 4 and housing are spaced a distance d from one another at the above-below direction of figure, the two remains on the common vertical plane.
Then, mobile mould S moves up by means of the driving mechanism (not shown) according to shown in the arrow among Figure 18.That is, moving die plate 202 moves to the rigging position that housing 3 is aimed at retainer 4 with respect to fixed bolster plate 209 upward displacements.On this rigging position, mobile mould S advances to the left of figure again, makes two templates 202 and 209 keep mutually contacting closely.Because the core pin 212 of molded shell has been on the position that does not hinder moving die plate 202, therefore when these two templates 202 when 209 closely contact mutually, the core pin 212 of molded shell just can not hinder moving die plate 202.Though there is a unloading hole that can hold core pin 212 position of the core pin 212 of molded shell in the outside of moving die plate 202 on this moving die plate 202 in the accompanying drawings.
After two templates 202 and 209 kept mutually contacting closely, retainer 4 just coupled together with the temporary transient fixing state and the previous section of housing 3.Though expression among the figure, the proximal part of molded good retainer 4 is still stayed in the retainer molded indentation 206B, and therefore, even exert pressure to retainer at the connection procedure middle shell 3 of retainer and housing 3, retainer can not drawn back in assembly process yet.Be being connected between housing 3 and the retainer 4 under the state that fixed bolster plate 209 and receiver sheet 208 are kept at a distance, to implement, and spring 10 has enough elastic force to keep out this pressure.
After assembly process is finished, mobile mould S gets back to the position that mould is opened again, the connector that housing 3 and retainer 4 have linked together is then stayed in the housing molded indentation 205, by a knock pin (not shown) connector is ejected mould then.Then, mobile mould S is moved down into home position (mold position; The position that mould is opened), then these two moulds just get ready for next molding process.
As mentioned above, in the present embodiment, the work step of molded shell 3 and retainer 4, and can carry out the assembling work step that they link together simultaneously, therefore, do not needed conveying operation in the conventional method and assembly process, and, also shortened from being dosed into the time of making product, and the cost of making has also reduced because of the shortening of technical process.In addition, different mechanographs, promptly housing 3 and retainer 4 can be shaped in a mould, and from the angle of mold management, this also is very favourable.
The 4th embodiment
Below, with reference to Figure 21-26 fourth embodiment of the present invention is described.At first, molded connector to describe with reference to Fig. 8.The same with second embodiment, though connector as described herein is the so-called preceding type connector that keeps, the present invention also can be used in the back and keeps the type connector.
The structure of the mould of the connector of making above-mentioned structure is described below.In the present embodiment, mould is installed in the injection molding equipment.In these accompanying drawings, only roughly represented in order to narrate for simplicity, to have omitted many details by part and parcel.Therefore, do not represent the many details in the above-mentioned connector construction among the figure, and only roughly represented the quantity and the shape of core pin (will describe afterwards) in the accompanying drawings for example.The mould of present embodiment comprises a mobile mould and a fixed die.Fixed die 2101 in the expression of accompanying drawing left side comprises that 2103, fixed bolster plates 2105 of a cavity adaptor plate (on the right side of figure) then are installed on the plate 2103 by a cushion block 2104.Two guide pin bushings 3114 that hold lead 2106 when mould is closed respectively embed the opposite end of fixed bolster plate 2105 respectively, and parallel with the axis of mould.The main core pin 2107 that is mainly used in a part of internal structure (part of retraction space 176 keeps projection 177 etc.) of molded shell 170 is installed on the fixed dam 2140, passes fixed bolster plate 2105, and aims at mobile mould 2102.
The retainer molded indentation 2108 that is mainly used in the outer frame part of molded retainer 171 forms on the surface of mobile mould at fixed bolster plate 2105, and separates some distances with main core pin 2107.The core pin 2109 that is used for a part of internal structure (part that temporarily keeps pawl 183, the part of the hook 186 of linking arm 179, or the like) of molded retainer 171 is installed on the fixation side baffle plate 2140, and parallel with main core pin 2107.The distal portions of core pin 2109 can stretch in the retainer molded indentation 2108, and can continue outwards outstanding from fixed die 2101.
Fixation side reclaiming plate 2110 is arranged between fixed bolster plate 2105 and the cavity adaptor plate 2103.This piece fixation side reclaiming plate 2110 links to each other with a driving mechanism (not shown), and can be reciprocating between cavity adaptor plate 2103 and fixation side baffle plate 2140.A pair of knock pin 2111 is installed on the fixation side reclaiming plate 2110, and this a pair of knock pin 2111 both had been used for molded retainer 171, also was used to eject the retainer that is molded as.Two knock pins 2111 pass fixation side baffle plate 2140 and fixed bolster plate 2105, can slide therein, and the centre is provided with a core pin 2109.The far-end of knock pin 2111 forms the part of retainer molded indentation 2108 usually, in particular, form the part of retainer 171 outsides, and, such when mobile according to Figure 24 when fixation side reclaiming plate 2110, these far-ends that contact with the retainer 171 that is molded as just eject retainer come.
Fixed die 2101 is connected with a driving mechanism (not shown), and can move along the above-below direction perpendicular to the figure of axis under the mould open mode.Therefore, fixed die 2101 can be reciprocating between the two positions, one is the mold position of molded retainer 171 and housing 170, and one is the rigging position (leaving above-mentioned mold position in vertical direction) that the retainer 171 that is molded as is aimed at the housing 170 that is molded as.
Mobile mould 2102 is arranged to and fixed die 2101 coaxial lines usually, and it is the same with fixed die, comprises a mobile side installing plate 2112.Be arranged on the left side of mobile side shield 2141 at the spaced-apart moving die plate 2113 and 2141 of fore-and-aft direction.Be provided with a spring 2118 between two blocks of moving die plates 2113 and 2141, this spring pushes moving die plate 2113 forward.
Above-mentioned mobile mould 2102 is connected with a driving mechanism (not shown), can between mold closed position and mold opened position, move by the left and right directions along figure, on mold closed position, fixed bolster plate 2105 keeps mutually closely contacting with preceding moving die plate 2113, on mold opened position, the spaced-apart predetermined distance of these two templates.
Above-mentioned two leads 2106 are installed on the mobile side shield 2142, pass two blocks of moving die plates 2113 and 2141 respectively along the direction parallel with axis.At preceding moving die plate 2113 on the surface of fixed die, housing molded indentation 2115 and retainer molded indentation 2116 have been formed, molded indentation 2115 common and main core pin 2107 are aimed at, and molded indentation 2116 is aimed at the core pin 2109 that is used for molded retainer 171 and two knock pins 2111 usually.Open the gate (not shown) of leading to two molded indentations 2115 and 2116 respectively, so the resin of fusion just charges in these two molded indentations by corresponding gate.
In mobile mould 2102, between mobile side shield 2142 and mobile side installing plate 2112, be provided with the pin plate 2117 that is used to eject the product that is molded as.This pin plate 2117 is connected with a driving mechanism (not shown), can move forward and backward along axis direction.
Being used for of molded shell 170 imbeds core pin 2119 and is installed in back moving die plate 2141, the extension of paralleling to the axis.This imbeds core pin 2119 (that is, when front and back moving die plate 2113 closely contacts with 2141 mutual maintenances) in the process of molded shell 170, puts in the housing molded indentation 2115 so that molded maintenance step 182 etc.But as above-mentioned two blocks of moving die plates 2113 and 2141 when separated from each other (, after molding process), the above-mentioned core pin 2119 of imbedding is just withdrawn from from housing molded indentation 2115, just withdraws from from the housing 170 that is molded as.
Be used for the knock pin 2120 that the connector with the housing 170 that links together and retainer 171 ejects is installed in pin plate 2117, and parallel with axis.The far-end of this knock pin 2120 is arranged to flush with the inner surface of housing molded indentation 2115 usually.But after housing 170 and retainer 171 linked together, when preceding pin plate 2117 was advanced forward, the far-end of this knock pin 2120 just stretched in the housing molded indentation 2115, ejected the connector that assembles.
The mould molded shell 170 that adopts above-mentioned the 4th embodiment and the step of retainer 171 are described below, and the installation step that housing and retainer are linked together.
Under the mould closure state (Figure 21), preceding moving die plate 2113 keeps mutually contacting closely with fixed bolster plate 2105, housing molded indentation 2115 closed backs form the space or the die cavity of a sealing, also has an enclosure space that forms by two retainer molded indentations 2108 and 2116 that on fixed die and mobile mould, form respectively, as the die cavity of molded retainer 171.Under this state, the resin of fusion charges in the die cavity of these two sealings by corresponding gate (not shown).Because main core pin 2107 and imbed core pin 2119 and stretch in the housing molded indentation 2115 has just formed the outer shape and its internal structure (retraction space 176 keeps projection 177 etc.) of housing.The die cavity of molded retainer 171 is formed by two molded indentations 2108 and 2116 of working in coordination, and core pin 2109 stretches in this die cavity, thereby the outer shape of retainer 171 and its internal structure (temporarily keeping pawl 183, linking arm 179 etc.) have just been formed.
Charge into the resin of fusion then, when the process preset time, during hardening of resin, as shown in figure 22, mobile mould 2102 is return, and mould is opened.After mould was opened, housing 170 was stayed in the housing molded indentation 2115, and retainer 171 is stayed in the retainer molded indentation 2108 of fixed die.Open in the process of mould at this, two blocks of moving die plates 2113 and 2141 leave mutually under the effect of spring 2118, resemble and withdraw from from the housing 170 that is molded as described above so imbed core pin 2119.As mentioned above, imbed core pin 2119 and be used for molded maintenance step 182 and other parts, before retainer 171 and housing 170 link together, from housing 170, do not withdraw from if imbed core pin 2119 in the assembling work step afterwards, will be unfavorable for assembly process.Therefore, withdraw from that to imbed core pin be essential operation.
Then, the driving mechanism (not shown) makes fixed die 2101 move to the top of figure.That is, fixed bolster plate 2105 is displaced to rigging position with respect to preceding moving die plate 2113, so just as shown in figure 23, retainer 171 is displaced to the position with housing 170 coaxial lines.
Then, fixation side reclaiming plate 2110 moves forward, and ejects (forming) retainer molded indentation 2108 so the retainer 171 that is molded as is ejected pin 2111 in fixing side form, and moves towards housing 170.At this moment, core pin 2109 is withdrawn from from retainer 171.Core pin 2109 is used for forming part such as temporary transient maintenance pawl 183 grades, if core pin 2109 not retainer 171 with from retainer 171, withdraw from before housing 170 is connected, will be unfavorable for assembly process.So before knock pin 2111 was packed retainer 171 into housing 171, core pin 2109 and 2119 will be withdrawn from, so just can not influence temporary transient maintenance pawl 183 and the engagement that keeps step 182 fully.So retainer 171 and housing 170 have just linked together.
Then, when fixation side reclaiming plate 2110 was got back to the home position, the connector that housing 170 and retainer 171 are linked together as shown in figure 25, was still stayed in the mobile mould.Then, when pin plate 2117 moved forward, knock pin 2120 promoted housing 170, so the connector that is under the confined state (temporary transient hold mode) is pushed out housing molded indentation 2115, fell down from mould.Take out after the connector, pin plate 2117 is got back to the home position, and mobile mould 2102 is also got back to the home position.Above-mentioned two moulds have all been got back to their home position, for next molding process is got ready.
As mentioned above, in the present embodiment, the work step of molded shell 170 and retainer 171, and the assembling work step that they are linked together, can carry out at the same time, therefore just not need the conveying work step that separates in the usual way and assembled work step, and, also shortened from being dosed into the time of making product, and the cost of making has also reduced because of the shortening of technical process.
In addition, in the present embodiment as long as the operation knock pin just can link together housing 170 and retainer 171.It is also contemplated that and utilize the closed operation of mould to realize assembly process.But at this moment the part that will move is very big, and energy needed is also just many.On the other hand, in the present embodiment, those parts that move are controlled at minimum limit, and simple in structure, and the operation energy needed is few.
Because different types of molded product, promptly housing 170 and retainer 171 can be made at same mould inner mould, so be very favourable from the angle of mold management.In addition, in the present embodiment, the core pin 2109 and 2119 of molded usefulness had all just been withdrawn from respectively from retainer 171 and housing 170 before assembly process, and therefore, these two parts just can successfully link together.
The 5th embodiment
The 5th embodiment of Figure 27-32 expression mould of the present invention.Molded connector is identical with connector described in the second and the 4th embodiment in the present embodiment.Seeing earlier 2101, fixed bolster plates 2105 of fixed die can move to end arm-tie 2104 closely contacts, and perhaps leaves its position.The spring 2121 that is arranged between this two boards 2104 and 2105 forces right-hand the leave end arm-tie 2104 of fixed bolster plate 2105 to figure.Be provided with the retaining device (not shown) and surpass predetermined value to prevent distance between the two.For make fixed bolster plate 2105 can be successfully towards or leave end arm-tie 2104 and move, be provided with two guide pillars 2106, this guide pillar stretches out from cavity adaptor plate 2103, pass end arm-tie 2104 and fixed bolster plate 2105, and can in fixed bolster plate 2105, slide, insert in the guide pin bushing 2114 that is arranged on the moving die plate 2113 respectively then.
A main core pin 2107 extends out from cavity adaptor plate 2103, and its distal portions inserts and runs through in the jack 2105 of fixed bolster plate 2105, and parallel with axis.When fixed bolster plate 2105 keeps with end arm-tie 2104 tight contacts (, under mould closure state shown in Figure 27), that directly relevant with molded shell 170 part is passed jack 2122 and is come out on the main core pin 2107, and stretches in the housing molded indentation 2115 of mobile mould.When this two boards 2104 and 2105 left mutually, the just withdrawal from housing molded indentation 2115 of this part of main core pin 2107 was ensconced in the jack 2122 fully.
The core pin 2109 of molded retainer 171 extends out from cavity adaptor plate 2103, passes a sliding eye 2123 that runs through fixed form 2105, and parallels to the axis.Under the mould closure state that fixed bolster plate 2105 and end arm-tie 2104 keeps closely contacting, the far-end of the core pin 2109 relevant with molded retainer 171 exposes from sliding eye 2123, stretches in the retainer molded indentation 2116 of mobile mould.When two boards 2104 and 2105 left mutually, the just withdrawal from retainer molded indentation 2116 of the far-end of core pin 2109 hid in the sliding eye 2123 fully.
A fixation side knock pin 2124 is installed on the cavity adaptor plate 2103, and is arranged between main core pin 2107 and the core pin 2109.Knock pin 2124 inserts in the fixed bolster plate 2105, can slide.When two moulds 2101 and 2102 when closed together, this fixation side knock pin 2124 is inserted in the unloading hole 2125 that forms on the moving die plate 2113.When fixed bolster plate 2105 leaves end arm-tie 2104, the far-end of knock pin 2124 basically with the flush of fixed bolster plate 2105.Shown in figure 32, push back a little when some when fixed bolster plate 2105 is moved side return pin 2127, knock pin 2127 is just stretched from fixed bolster plate 2105, contacts with the housing of the connector that assembles, so just eject connector from mould.
The the 3rd and the 5th embodiment is in the difference aspect the mobile mould 2102, is not that retainer 171 is ejected, and goes to be connected with housing 170, but housing is ejected, and goes to be connected with retainer.In particular, between mobile side template 2113 and mobile side installing plate 2112, be provided with the pin plate 2129 and 2130 of two coaxial lines by a dottle pin 2128.Knock pin 2131 is installed on first pin plate 2129, and is parallel with axis, and is connected with a driving mechanism (not shown), so that can move back and forth along axis.The far-end of above-mentioned knock pin 2131 is arranged to basically a flush with housing molded indentation 2115 usually.As shown in figure 31, when first pin plate 2129 and second pin plate 2130 are advanced a predetermined formation together forward, knock pin 2131 just ejects the housing 170 that is molded as from housing molded indentation 2115, housing is contacted with retainer 171 under temporary transient hold mode.The imbed core pin 2119 relevant with molded shell is embedded in the moving die plate 2113, and its far-end stretches in the housing molded indentation 2115.
Second pin plate 2130 also is connected (this driving mechanism can be same driving mechanisms with the driving mechanism of first pin plate 2129 both, also can be independent driving mechanism) with a driving mechanism, also can be reciprocating along axis.Return pin 2127 is contained on second pin plate 2130, and is parallel with axis, and the far-end of this return pin 2127 is arranged to basically the flush with moving die plate 2113 usually.As shown in figure 31, when second pin plate 2130 and first pin plate 2129 were advanced forward together, above-mentioned return pin 2127 contacted with fixed bolster plate 2105.Then, when return pin 2127 is advanced a predetermined stroke more forward, return pin 2127 just overcomes the pressure of spring 2121, fixed bolster plate 2105 is rolled back, so the connector that under temporary transient hold mode two parts the is linked together side knock pin 2124 that just is fixed has pushed up.
The mould structure of the 5th embodiment under mould closure state as shown in figure 27, charges into the resin of fusion in the die cavity that forms, thereby is molded into housing 170 and retainer 171 as mentioned above between two templates 2105 and 2113.Then, when the hardening of resin of fusion, mobile mould 2102 just returns.Because the return movement of mobile mould 2102, fixed bolster plate 2105 leaves end arm-tie 2104 under the effect of spring 2121, the result, and main core pin 2107 is just withdrawn from from the housing 170 that is molded as, and core pin 2109 is then withdrawn from (seeing Figure 28) from retainer 171.As shown in figure 29, when mobile mould 2102 is further return, just reached the state that mould is opened, at this moment, moving die plate 2113 and fixed bolster plate 2105 are separated from each other.
Then, fixed die 2101 moves to the top of figure by means of the driving mechanism (not shown), makes fixed bolster plate 2105 with respect to moving die plate 2113 displacements, promptly, move on to a rigging position, retainer 171 and housing 170 coaxial lines (referring to Figure 30) on this position.
When fixed die moved to above-mentioned rigging position, first and second pin plates 2129 and 2130 just moved up as shown in figure 31 like that.As a result, knock pin 2131 is released housing molded indentation 2115 to housing 170, and housing 170 and the retainer 171 that is clamped in the fixed die are worked good.When from housing molded indentation 2115, being ejected with housing 170, imbedding core pin 2119 withdraws from from housing 170, therefore, imbed core pin 2119 and can not influence (for example being connected of housing and retainer 171, the temporary transient engagement that keeps between pawl 183 and the maintenance step 182), housing and retainer are then linking together under temporary transient hold mode.Meanwhile, the far-end of return pin 2127 keeps and the slight state of contact in the surface of fixed bolster plate 2105, and the front end of housing 170 then keeps contacting with the far-end of fixation side knock pin 2124.
Then, shown in figure 32, when having only second pin plate 2130 to move forward, mobile side return pin 2127 overcomes the pressure of spring 2121, and fixed bolster plate 2105 is recalled.As a result, fixation side knock pin 2124 ejects housing 170, so the connector that housing 170 and retainer 171 are linked together just ejects in the retainer molded indentation 2108 from fixed die, that is, fall down from mould.Like this, connector has been got, and then, first and second pin plates 2129 and 2130 are got back to their home position respectively, and whole fixed die 2101 also gets back to the home position, and mould is that next molding process is got ready.
As mentioned above, the 5th embodiment is the same with the 4th embodiment, can be at an easy rate with low cost manufacturing and assembly connector.
Other structures of present embodiment are identical with the 4th embodiment, and the effect that reaches is also identical.
The present invention can carry out various improvement, and following various improvement all fall within the scope of the present invention:
In the 3rd embodiment, although be have only mobile mould S up and down direction and left and right directions move, but also can all move by two moulds.
In the 3rd embodiment, retainer 4 that is molded as and the assembly process that the housing 3 that is molded as links together are realized by the closed again operation of mould.But, also can replace with following structure:
For example, a stripper pin (not shown) is set in moving die plate 202.When finished as shown in figure 18 molded after, stripper pin is just pushed the housing 3 that is molded as to retainer 5, thereby housing and retainer are linked together.The connector that has assembled falls down from mould owing to the weight of itself breaks away from housing molded indentation (also a knock pin can be set for this reason).
In the 4th and the 5th embodiment, though what describe is the structure that the housing of connector and retainer are linked together, but the present invention also can be applied to other various resin molded goods, and the quantity of the resin molded goods that connected is not limited to two, also can be used for the structure that plural part is linked together.
Though in the 4th and the 5th embodiment, have only fixed die to move, also can allow mobile mould move, perhaps allow mobile mould and fixed die all move.
In addition, according to the present invention, when the housing of connector and retainer are shaped, can in the housing molding mould of connector and retainer finishing die, charge into the resin of different materials or color, with connector shell and the retainer of making different materials or different colours.
The 6th embodiment
Below, describe preferred the 6th embodiment of the present invention in detail with reference to Figure 33-39.Though present embodiment is that the present invention also can be used for the back and keep the type connector at the preceding maintenance type connector described in top Fig. 6.One usually, its each pith is as described below for the mould of finishing method of the present invention is contained on the injection molding equipment, but for convenience of explanation, accompanying drawing has all been simplified, and mould is strictly not corresponding with connector shown in Figure 6.
The mould of present embodiment comprises a mobile mould and a fixed die, and above-mentioned mobile mould S comprises a moving die plate 302 that is fixed on the mobile die-cushion plate 301.On the molded surface of moving die plate 302, formed the housing molded indentation 305 of the housing 3 of the connector that is used to be shaped.On this molded surface, directly over groove 305 stroke the molded part 306 (referring to accompanying drawing) of accepting of retainer of the retainer 4 that is used to be shaped.On this molded surface, that part under above-mentioned housing molded indentation 305 has been opened a unloading hole 307.Above-mentioned mobile mould S is connected with a driving mechanism (not shown), and can move a predetermined stroke to the left and right directions of figure.
Said fixing mould R comprises a briquetting 310, and this briquetting is installed on the fixation side die-cushion plate R1 by an installing plate 309.An intermediate plate 311 is arranged on the place ahead of moving die plate 302, and relative with it.
A spring SP is located between intermediate plate 311 and the installing plate 309, and it is towards the direction pushing intermediate plate 311 that leaves installing plate 309.In the middle of this two boards, be provided with the stop assembly (not shown), surpass predetermined value in order to prevent the distance between intermediate plate 311 and the installing plate 309.On the surface of moving die plate 302 1 sides, formed retainer molded indentation 312 at intermediate plate 311.This retainer molded indentation 312 is arranged on retainer is molded and accepts on the position that part 306 aims at, when mould is closed, just formed the die cavity of retainer 4 by molded part 306 and flashboard part 313 (following the describe again) space of being defined of accepting of this groove 312, retainer.
The sliding pin 314 of forming travel mechanism is in the present invention packed in the intermediate plate 311, so that slide along the above-below direction of figure.The far-end of this sliding pin 314 is arranged to flush with the inner surface of retainer molded indentation 312 usually, and when molding process was finished, this far-end can eject, and the retainer 4 that is molded as is pushed a jack 315 (following description again).This motion of retainer has guiding, for example, can be by means of concavo-convex cooperation (not expression among the figure, for example, can on the outer surface of retainer 4, form some projectioies, and on the inner surface of retainer molded indentation 312, correspondingly form the grooves that cooperate with these projectioies), therefore, retainer can keep it in the molded attitude that is had in good in mobile.
Jack 315 passes intermediate plate 311, is arranged to aim at housing molded indentation 305, and extends along the left and right directions of figure.A core pin 316 is contained in intermediate plate 311 on the surface of housing molded indentation 305, and jack 315 opens wide towards core pin 316.Core pin 316 is arranged to and housing molded indentation 315 coaxial lines, and an expansion 316A is arranged on its outer peripheral edge.When mould was closed, core pin 316 entered in the housing molded indentation 305, formed the die cavity of a molded shell 3, and this die cavity extends to the inside or the blind end of groove 305 from the inside slightly zone of the open end of groove 305.Core pin 316 is connected with a slide mechanism (not shown), can be along the surface of intermediate plate 311, above-below direction towards drawing, reciprocating between the two positions, one of them position is the position of core pin 316 and housing molded indentation 305 coaxial lines, and another position is core pin 316 and the position that unloads hole 307 coaxial lines.
After mould was opened, when molded good retainer 4 and molded good housing 3 were also stayed in molded indentation 305 and 312 respectively, those surfaces that will couple together of retainer 4 and housing 3 just all had been exposed on relative to each other the direction.The gate (not shown) of leading to these two molded indentations 305 and 312 is respectively opened, so the resin of fusion just charges in these two molded indentations 305 and 312 by corresponding gate.
The briquetting 310 that is contained on the installing plate 309 can insert in the jack 315, and on briquetting 310, formed one outstanding forward, with the extension of the upper surface flush of jack on figure.When mould was closed, this extension was close to the front surface of moving die plate 302, plays above-mentioned flashboard part 313, and retainer molded indentation 312 is closed.What form a step on that part below briquetting 310 is arranged in figure flashboard part 313 adds pressure surface 317.When mould was closed, this added pressure surface 317 and forms a space 310A, and the height in this space is a bit larger tham the height of retainer 4, and thickness is slightly smaller than the thickness (referring to Figure 35) of retainer.Because this structure just can be pressed the molded good retainer 4 that enters jack 315 afterwards forward from behind, makes it and is arranged in housing molded indentation 305, and couple together with respect to the molded good housing 3 that the open end of this groove 305 is dropped back slightly.
The mould molded shell 3 of the above-mentioned structure of employing and the operation and the assembly process of retainer 4 are described below.
Under the state that mould shown in Figure 33 is opened, when mobile mould S when fixed die R moves, above-mentioned mobile side template 302 at first is pressed on the intermediate plate 311.When mobile mould S further advanced forward, intermediate plate 311 was just withdrawn, and compresses spring SP simultaneously, closely contacted with installing plate 309.At this moment, core pin 316 is inserted in the housing molded indentation 305, forms the die cavity of molded shell.Simultaneously, retainer molded indentation 312 cooperates with the molded part 306 of accepting of retainer, and in the briquetting 310 insertion jacks 315, so flashboard part 313 leans against on the moving die plate 302, retainer molded indentation 312 is closed.As a result, just accept the die cavity that part 306 and flashboard part 313 have formed molded retainer 4 by retainer molded indentation 312, retainer are molded.In this state, the resin of fusion is charged in these two molded indentations (referring to Figure 34 and 35).
Then, through after a while, when hardening of resin, mobile mould S returns, and mould is opened.When briquetting 310 is recalled from jack 315, when getting back to its home position, retainer 4 is still stayed in the retainer molded indentation 312 of fixed bolster plate, and housing 3 is still stayed in the housing molded indentation 305 of moving die plate 302 (referring to Figure 36).Then, core pin 316 moves to the below of figure, enters in the horizontal direction the position with unloading hole 307 coaxial lines.
Then, sliding pin 314 moves to the below of figure, and molded good retainer 4 is released retainer molded indentation 312.At this moment, because the above-mentioned concavo-convex matching relationship between retainer 4 and the jack 315, the motion that retainer 4 enters in the jack 315 has guiding, can not change the attitude of retainer 4 when molded finishing.As a result, retainer 4 is relative on common axis with housing 3 on the horizontal direction of figure.
Then, after sliding pin 314 was got back to its home position, mobile mould S moved forward again, the compression spring SP in again the mould closure.As a result, briquetting inserts in the jack 315 again, so the rear surface that its pressure surface 317 just promotes retainer 4.As a result, this retainer 4 just combines with this housing in the front of housing 3 and this housing connects into temporary transient hold mode.At this moment, core pin 316 is inserted in the unloading hole 307, therefore can not hinder mobile mould S.
Like this; assembly process has just been finished; then; when mobile mould S returns again; just stay among the mobile mould S by housing 3 and retainer 4 connector of forming that links together; by the shedding mechanism (not shown) this connector is ejected from mould again, for example, use with the coacting knock pin of the die opening mechanism of mobile mould it is ejected.So these two moulds are just got ready for next molding process.
As mentioned above, in the present embodiment, the work step of molded shell 3 and retainer 4 and can carry out the work step that they link together at the same time, therefore, conveying operation in the conventional method and assembly process have not just been needed, and because technical process has shortened, product also shortened from the time that is dosed into out finished product.In addition, can also reduce manufacturing cost.In addition, because different types of molded products, i.e. housing 3 and retainer 4, can be in a mould molded come out also is very favourable from the angle of mold management.
The 7th embodiment
Below with reference to Figure 40-45 seventh embodiment of the present invention is described.At first, molded connector is to illustrate with reference to Fig. 8.The same with those former embodiment, though what describe is the connector of preceding maintenance type,, the present invention also can be used for the connector that the back keeps type.
The structure of the mould of the connector of making said structure is described below.In the present embodiment, mould is installed in the injection molding equipment.In the accompanying drawings, only roughly represented part and parcel,, omitted details wherein for describing for simplicity.Therefore, do not represent the details of above-mentioned connector construction among the figure, for example, only roughly represented the quantity and the shape of core pin (will be described below) among the figure.
The mould of present embodiment comprises a mobile mould and a fixed die.Fixed die 3101 in the expression of accompanying drawing left side comprises that 3103, fixed bolster plates 3105 of a cavity adaptor plate (on the right side of accompanying drawing) then are installed on the plate 3103 by an end arm-tie 3104.Lead 3106 is arranged on the end of end arm-tie 3104, is used to the open and close mould motion guide of two moulds.Spring 3121 is arranged between end arm-tie 3104 and the fixed bolster plate 3105, and it forces fixed bolster plate 3105 to leave end arm-tie 3104.The main core pin 3107 that is used for molded shell 170 a part of internal structures (parts of retraction space 176 and maintenance projection 177 grades) is fixedly mounted on end arm-tie 3104, and is parallel with axis, and passes fixed form 3105, can slide therein.(part is temporarily to keep pawl 183 to molded retainer 171 a part of internal structures, a part is the hook 186 of linking arm 179, or the like) core pin 3109 be installed on the end arm-tie 3104, parallel with axis, and separate predetermined distance with main core pin 3107.
Formed the guide rail 3117 that is flute profile at fixed bolster plate 3105 on that surface of mobile mould, this guide rail 3117 extends from the far-end of fixed bolster plate 3105 (the figure) upper end to main core pin 3107 on the direction perpendicular to axis.Formed two apertures in the bottom of guide rail 3117, the distal portions of core pin 3109 and main core pin 3107 passes this two apertures in the mode of close-fitting respectively.As shown in figure 40, when fixed bolster plate 3105 kept mutually closely contacting with end arm-tie 3104, core pin 3109 and main core pin 3107 were passed guide rail 3117 and are entered in the mobile mould.Shown in Figure 41-44, when end arm-tie 3104 and fixed bolster plate 3105 were separated from each other, the far-end of core pin 3109 left the predetermined distance of guide rail 3117, and the far-end of main core pin 3107 then flushes with guide rail 3117 basically.
When mould was closed, as shown in figure 40, guide rail 3117 and moving die plate 3113 formed the die cavity R of a molded retainer together, and at this moment, as described above, core pin 3109 is inserted in the die cavity R of this molded retainer.Knock-out pin 3118 close-fittings are in guide rail 3117, so that move along guide rail, the far-end of this knock-out pin 3118 exposes usually in the die cavity R of molded retainer.Knock-out pin 3118 is connected with a slide mechanism (not shown), can move at the above-below direction of figure, and when the mould closure was carried out molding process, the surface of knock-out pin 3118 far-ends formed the part of the die cavity R of molded retainer.Above-mentioned knock-out pin 3118 also plays travel mechanism, and after molded finishing, its is pushed to retainer 171 of being molded as on the position in the place ahead of main core pin 3107.Then, as shown in figure 44, after housing 170 and retainer 171 linked together, the far-end of pushing pin 3118 contacted with housing 170.
Mobile mould 3102 is arranged to and fixed die 3101 coaxial lines, and the same with fixed die, comprises a mobile side installing plate 3112.Moving die plate 3113 is bearing in (among the figure) left side of installing plate 3112 by cushion block 3137.Mobile mould 3102 is connected with a driving mechanism (not shown), can move predetermined stroke along the left and right directions of figure.
Two guide pin bushings 3114 that when the mould of closure is hidden end into moving die plate 3113, hold above-mentioned two guide pillars 3106 respectively extension of paralleling to the axis.On that side or surface of fixed bolster plate 3105, formed a groove 3108 that is used to form the die cavity R of molded retainer at moving die plate 3113, the position of this groove is relative with core pin 3109.In that part that is positioned on this surface of moving die plate 3113 below the groove 3108, also have a groove 3115 for the die cavity H that forms molded shell, its position is relative with main core pin 3117.Form a projection 3120 at moving die plate 3113 on the surface of fixed bolster plate, when mould was closed, this projection 3120 stretched in the guide rail 3117, to form the die cavity R of molded retainer.The rear side that core pin 3119 is embedded in moving die plate 3113 upper grooves 3115 of imbedding that is used for molded shell 170, the extension of paralleling to the axis, this is imbedded core pin 3119 and protrudes in the groove 3115.Though not expression among the figure, the gate that leads to two grooves (being retainer molded indentation and housing molded indentation) 3108 and 3115 respectively is opened, so the resin of fusion just charges into this two grooves by corresponding gate.
Between moving die plate 3113 and mobile side installing plate 3112, be provided with two pin plates 3129 and 3130 by a cushion block 3128.First pin plate 3129 and second pin plate 3130 all and drive unit (not shown, can be common drive unit, also can be different drive units) connect, and can move along axis independently of each other.A knock pin 3124 is installed on first pin plate 3129, and is parallel with axis, passes second pin plate 3130 and mobile side template 3113, and can slide therein.Knock pin 3124 is used for the molded good housing 170 that will be connected with retainer 171 is ejected.Return pin 3127 is installed on second pin plate 3130, and is parallel with axis, passes mobile side template 3113, and can slide therein.
Usually, the position of the far-end of return pin 3127 basically with the flush of moving die plate 3113, when second pin plate 3130 was advanced forward, return pin 3127 made fixed bolster plate 3105 overcome the pressure of spring 3121 and returns.
The above-mentioned mould molded shell 170 of employing present embodiment and the technical process and the assembling process of retainer 171 are described below.
At first, two moulds 3101 and 3102 are closed together, and two templates 3105 are closely contacted mutually with 3113.At this moment, the distal end exposed of pushing pin 3118 is in the die cavity R of molded retainer.Between above-mentioned two templates 3105 and 3113 that closely contact, the die cavity H of molded shell and the die cavity R of molded retainer have been formed.At this moment, in the die cavity R of core pin 3109 inserted mode system retainers, main core pin 3107 and imbed core pin 3119 then in the die cavity H of inserted mode system housing.
Under the state of this mould closure, the resin of fusion charges in the die cavity R of the die cavity H of molded shell and molded retainer by the gate (not shown).Through preset time, after hardening of resin, mobile mould is moved back into state shown in Figure 41.In particular, when mobile mould 3102 returned, fixed bolster plate 3105 left end arm-tie 3104, result under the effect of spring 3121, core pin 3109 is just withdrawn from from the retainer 171 that is molded as, and main core pin 3107 is also withdrawn from from the housing 170 that is molded as.
Then, when mobile mould 3102 was further mobile backward, above-mentioned two templates 3105 and 3113 were separated from each other, as shown in figure 42, the retainer 171 that is molded as is clamped in fixation side (guide rail 3117), and the housing 170 that is molded as then is clamped in mobile side (housing molded indentation 3115).
Under the state that this mould is opened, start the slide mechanism (not shown), pushing pin 3118 is moved to the below of figure along guide rail 3117.As a result, pushing pin 3118 promotes retainer 171 along guide rail 3117, so retainer 171 just as shown in figure 43, is in the place ahead of main core pin 3107.Under this state, the rear side of retainer 171 abuts against on the main core pin 3107, thereby by this main core pin supporting.
Like this, retainer 171 and housing 170 are on the position relative to each other on a common axis, and under this state, first and second pin plates 3129 and 3130 are promoted forward by the driving mechanism (not shown).As a result, knock pin 3124 ejects housing 170 to come from housing molded indentation 3115, so retainer 171 civilian dresses are gone in the case part 173, housing and retainer are linked together.3127 of above-mentioned return pins withstand fixed bolster plate 3105, do not play promotion.Though what represent among Figure 44 is that housing 170 and retainer 171 have linked together, housing 170 has ejected fully from groove 3115, but preferably housing 170 is connected by this way with retainer 171, that is, housing 170 also pack into slightly groove 3115 openings the end a little.
Then, when second pin plate 3130 was advanced forward, return pin 3127 overcame the pressure of spring 3121, and fixed bolster plate 3105 is returned.Therefore, the connector that assembles is just ejected from behind by main core pin 3107, falls down from mould.Like this, just the connector that is under the temporary transient hold mode has been taken out from mould.
As mentioned above, the work step of molded shell 170 and retainer 171, and the assembling work step that they link together carried out at the same time, therefore, just do not need the independently conveying in the conventional method and assembled work step, and because technical process has shortened, product also shortened from the time that is dosed into out finished product.In addition, can also reduce manufacturing cost.
In the present embodiment, as long as operation knock pin 3124 just can link together housing 170 and retainer 171, as long as operation return pin 3127 just can be unloaded the connector that assembles down.It is also contemplated that the operating process that utilizes whole close die realizes this assembling and discharge process.But in this case, those parts that move are very big, and the energy that needs is just many.On the other hand, in the present embodiment, the part that moves remains on minimum scope, and simple in structure, and the operation energy needed seldom.
Different types of molded product, promptly housing and retainer can form in a mould, and from the angle of mold management, this is very favourable.In the present embodiment, core pin was withdrawn from before assembly process from housing 170 and retainer 171, therefore had to make this two advantages that part successfully links together.
The present invention can have various modification, and following various modification all fall within the scope of the present invention:
In the 6th embodiment, retainer 4 that is molded as and the assembly process that the housing 3 that is molded as links together are realized with the closed again operation of mould, so the close mechanism of mould is also as assemble mechanism.But, also can replace with following assemble mechanism.
For example, core pin 316 can be set on the position that pressure block 310 is set, when mould was closed, core pin 316 was passed jack 315, formed the die cavity of molded shell in housing molded indentation 305.

In addition, according to the present invention, when the housing of connector and retainer are shaped, can in connector finishing die and retainer finishing die, charge into the resin of different colours and different materials, thereby can produce the connector shell and the retainer of different materials and different colours.
The 8th embodiment
Below with reference to Figure 46-53 eighth embodiment of the present invention is described.Though what describe is connector at preceding maintenance type,, the present invention also can be used for the connector that the back keeps type.The mould of realizing the inventive method is installed in the injection molding equipment, and the pith of this mould will be described below, but for describing for simplicity, Figure 46 to 53 has been simplified, and this mould does not have strictly corresponding with the connector among Fig. 6.Figure 46 to 51 is the sectional drawings along the Q-Q line of the P-P line of Figure 52 and Figure 53.
The mould of present embodiment comprises a fixed die S and a mobile mould R.This mobile mould R comprises that one is installed on the base plate 401, can be around the moving die plate 402 of axis X rotation.The surface of moving die plate 402 is towards fixed die S, and as a molded surface 402A, the molded part 412 of accepting of housing molded indentation 411 and retainer all forms on this molded surface 402A.In the present embodiment, two housing molded indentations 411 and two molded parts 412 of accepting of retainer are arranged, shown in Figure 53.The straight line of having arranged two grooves 411 is perpendicular to there being a pair of straight line of accepting part 412, and this a pair of groove 411 and this be arranged on the circumference accepting part 412, and the center of circumference is on moving die plate 402 rotational axis x.Moving die plate 402 is connected with a driving mechanism (not shown) that has turn device, can rotate 90 degree (once can rotate 90 degree to a direction) to and fro around pivot center.
Fixed die S and mobile mould R are arranged to coaxial line, and it comprises a fixed bolster plate 407 that is fixedly mounted on the receiver sheet 406 on the installing plate 405 and is installed in receiver sheet 406 the place aheads.Be used as molded surface 407A towards the surface of moving die plate 402 on the fixed bolster plate 407.Retainer molded indentation 407B forms on molded surface 407A, and usually molded to accept part 412 relative on same axis with two retainers.Be provided with a spring SP between receiver sheet 406 and fixed bolster plate 407, this spring forces fixed bolster plate 407 to leave receiver sheet 406.Between receiver sheet 406 and fixed bolster plate 407, be provided with suitable stop assembly (not shown), surpass predetermined numerical value to prevent the distance between the two.
The proximal part of the core pin 409 of a pair of molded retainer is installed in the receiver sheet 406, and aims at retainer molded indentation 407B in the fixed bolster plate 407 respectively.Therefore, the proximal part of the core pin of these two molded retainers just is contained in the receiver sheet 406, and their distal portions inserts the jack 409A that runs through that flatly forms respectively on fixed bolster plate 407, can slide therein, these two jack 409A communicate with retainer molded indentation 407B respectively.Under mould open mode shown in Figure 46, the far-end of the core pin 409 of each molded retainer is withdrawn from the retainer molded indentation 407B of collaborative work, and when receiver sheet 406 kept mutually closely contacting with fixed bolster plate 407, the far-end of this core pin 409 just was exposed among the retainer molded indentation 407B.When these two templates 402 and 407 when closed together, at the die cavity of accepting to have formed between the part 412 molded retainer of retainer molded indentation 407B and molded retainer.
The core pin 410 of a pair of molded shell also is contained on the receiver sheet 406.These two core pin 410 are arranged to respectively aim at the housing molded indentation 411 in the moving die plate 402, and these a pair of core pin 410 residing planes are vertical with the core pin 409 residing planes of a pair of molded retainer.Two core pin 410 are arranged on the circumference, and the center of circumference is on the axis of fixed die S, just on the rotational axis x of mobile mould R.The proximal part of the core pin 410 of two molded shells also is contained in the receiver sheet 406, and their distal portions inserts respectively among the jack 410A that flatly runs through fixed bolster plate 407.The core pin 410 of two molded shells be arranged to respectively usually in the horizontal direction with moving die plate 402 on housing molded indentation 411 coaxial lines, and their far-end is arranged to flush with molded surface 407A, perhaps withdrawal is a bit slightly.But as shown in figure 47, when mould was closed, the core pin 410 of each molded shell was all charged in the housing molded indentation 411 of collaborative work, so that form the die cavity of molded shell between them.
After mould was opened, when molded good retainer 4 and housing 3 are also stayed in molded indentation 407B and 411 respectively, all came out in those surfaces that will link together on the molded good housing 3 of pairing and the retainer 4, and respectively relative to each other.Open the gate (not shown) of leading to each molded indentation 407B and 411 respectively, the resin of fusion just charges in these molded indentations by corresponding gate.
Mobile mould R is connected with a driving mechanism (not shown), can move around by the left and right directions in figure, therefore, mobile mould can move between the two positions, a position is that moving die plate 402 keeps tight position contacting with fixed bolster plate 407, and the fixed bolster plate 407 that promptly abuts against on the moving die plate 402 keeps tight position contacting with receiver sheet 406; The position that to be moving die plate 402 separate with fixed bolster plate 407, another position.
The mould molded shell 3 that utilizes said structure and the technical process and the assembling process of retainer 4 are described below.
Under mould open mode shown in Figure 46, when mobile mould R when fixed die S moves, moving die plate 402 at first is pressed on the fixed bolster plate 407.Advance forward when mobile mould R continuation, in the compression spring, fixed bolster plate 407 closely contacts with receiver sheet 406.The result, the core pin 409 of two molded retainers is advanced forward along corresponding jack 409A, arrive retainer molded indentation 407B respectively, the result, the part 412 of accepting of the retainer molded indentation 407B of each core pin 409, collaborative work and the molded retainer of collaborative work is joined together, and forms the die cavity of molded retainer.And the core pin 410 of these two molded shells is charged into respectively in the housing mold pressing groove 411, so the die cavity of molded shell just forms between the molded indentation 411 of each core pin 410 and collaborative work.In this state, the resin of fusion is injected in each groove.
Then, when through after a while, behind the hardening of resin, mobile mould is return, and opens mould.As a result, each housing 3 is stayed respectively in the housing molded indentation 411, and retainer 4 is stayed respectively in the retainer molded indentation 407B.After mould was opened, fixed bolster plate 407 left receiver sheet 406, so core pin 409 and 410 is got back to their home positions respectively.
Like this, finished and opened mould after the molding process, moving die plate 402 revolves and turn 90 degrees by means of the rotary drive mechanism (not shown) rotation axis X (axis of mobile mould) that rotates then.As a result, two housings 3 turn to respectively in the horizontal direction of figure and the relative position of two retainer 4 coaxial lines.Then, mobile mould R advances forward again, make moving die plate 402 contact (also can be to make template 402 move to the position close) with fixed bolster plate 407, so two retainers 4 just are being connected with the leading section of two housings 3 under temporary transient hold mode respectively with template 407.The bottom of each retainer 4 is still being supported by the inner surface of retainer molded indentation 407B, so when retainer 4 cooperated with housing 3, retainer 4 can not return.
Like this, just finished assembly process, and, when fixed die S returns again, each connector that housing 3 and retainer 4 are linked together is stayed respectively in each housing molded indentation 411, all uses a knock pin (not shown) to make it eject from mould.Then, moving die plate 402 rotates 90 degree in the opposite direction, forwards the home position to, gets ready so two mould S and R just be next molding process.
As mentioned above, in the present embodiment, the work step of molded shell 3 and retainer 4, and the assembling work step that they link together carried out at the same time, therefore, just do not needed independently conveying in the conventional method and assembling work step, and because technical process has shortened, product has also shortened from the time that is dosed into out finished product.In addition, because different types of molded products, i.e. housing 3 and retainer 4, can be in a mould molded come out from mold management, also is very favourable.
The 9th embodiment
Figure 54-61 represents the ninth embodiment of the present invention.In this embodiment, mould comprises a mobile mould M and a fixed die N.Mobile mould M comprises a packaged moving die plate 416 on decking 415.The housing molded indentation 417 of a molded shell forms on the molded surface of moving die plate 416.Mobile mould M is connected with a driving mechanism (not shown), and whole mobile mould M can move back and forth at the left and right directions of figure.
Fixed die N comprises the fixed form 419 and the intermediate die plate 420 that are fixedly mounted on the installing plate 418, and this intermediate die plate is connected with installing plate 418, is arranged between fixed form 419 and the moving die plate 416.The part 421 of accepting of the molded retainer of molded retainer 4 forms on the molded surface of fixed form 419.The height of accepting part 421 of molded retainer is identical with the height of housing molded indentation 417, but discord housing molded indentation 417 is aimed on the horizontal direction of figure.

A spring SP is arranged between fixed form 419 and outside framework 424, and this spring forces outside framework 424 to leave fixed form 419.Between fixed form 419 and outside framework 424, be provided with the stop assembly (not shown), surpass predetermined value to prevent distance between the two.
The mould of the 9th embodiment and the foregoing description have same structure, and the mode of its use is as follows.Whole mobile mould M is promoted to move to fixed die N by the driving mechanism (not shown).As a result, moving die plate 416 at first is close to intermediate die plate 420 and outside framework 424, and then, when mobile mould was advanced further, intermediate plate 420 and outside framework 424 closely contacted with fixed form 419 in the compression spring SP.Like this, two mould M and N are just closed together, and simultaneously, the core pin 423 of molded shell is inserted in the housing molded indentations 417, so just formed the die cavity of molded shell 3 between them.Equally, retainer molded indentation 426 enters the position that part 421 is aimed at of accepting with molded retainer, forms the die cavity of molded retainer 4 between them.Under such state, the resin of fusion is charged in these two die cavitys.
Then, when through after a while, behind the hardening of resin, mobile mould M returns, and opens mould.As a result, each housing 3 is stayed in the moving die plate 416, and retainer 4 is stayed the retainer molded indentation 426 interior (seeing Figure 56) of intermediate plate 420.Then, make intermediate plate 420 rotate 90 degree with the rotating mechanism (not shown) around bearing pin 425.As a result, intermediate plate 420 turns, and retainer is aimed at housing 3 on the horizontal direction of figure.Then, mobile mould M advances once more, and do not recompress spring SP and arrive and intermediate plate 420 tight position contacting this moment.As a result, retainer 4 is connected with the leading section of housing 3 under temporary transient hold mode.
So just finished assembly process, when mobile mould M return again, the connector that housing 3 and retainer 4 are linked together was stayed in the housing molded indentation 417, and by a knock pin (not shown) it was ejected, and made its demoulding.Then, the core pin 423 of molded shell is got back to its home position, and intermediate plate 420 overturns again, then two reset conditions that mould has all been got back to them, for next molding process is got ready.
The 9th embodiment has the effect same with the 8th embodiment, also can be used for the connector that the back keeps type.
The tenth embodiment
Below, describe preferred the tenth embodiment of the present invention in detail with reference to Figure 62-67.In the present embodiment molded connector as shown in Figure 8.The same with those former embodiment, though described in the present embodiment be preceding maintenance type connector, the present invention also can be used for the back and keep the type connector.
The structure of the mould of molded connector with said structure is described below.In the present embodiment, mould is contained on the injection molding equipment, in the accompanying drawing, has only roughly represented each pith, for convenience of explanation, has omitted some details.Therefore, do not represent the details of said structure connector among the figure, and only roughly represented the quantity and the shape (will be described below) of core pin in the accompanying drawings.
The mould of present embodiment comprises a mobile mould and a fixed die.The fixed die of representing in the left side of figure 4101 comprises a cavity adaptor plate 4103, and a fixed bolster plate 4105 (on the right side of figure) is installed on the above-mentioned plate 4103 by a cushion block 4104.Two fairleads 4114 are imbedded respectively in two relative ends of fixed bolster plate 4105, and parallel with the axis of mould.The main core pin 4107 that is mainly a part of internal structure (a part of retraction space 176, maintenance step 170 etc.) of molded shell 170 is installed in the fixed bolster plate 4105, and points to mobile mould 4102 abreast with axis.
The retainer molded indentation 4108 of outside framework part that is mainly molded retainer 171 is the forming on the surface of mobile mould of fixed bolster plate 4105, and it and main core pin 4107 separate some distances slightly.The core pin 4109 that is used for a part of internal structure (part of hook 186 that temporarily keeps a part, the linking arm 179 of pawl 183, or the like) of molded retainer 171 is installed in the fixed bolster plate 4105, and parallel with main core pin 4107.The distal portions of core pin 4109 can be charged in the retainer molded indentation 4108, and can also continue from fixed die 4101 protruding.
Between fixed bolster plate 4105 and cavity adaptor plate 4103, be provided with a fixation side reclaiming plate 4110.This fixation side reclaiming plate 4110 is connected with a driving mechanism (not shown), can be reciprocating between cavity adaptor plate 4103 and fixation side base plate 4140.A pair of pushing pin 4111 is installed on the fixation side reclaiming plate 4110, and this a pair of pushing pin 4111 both had been used for the molded of retainer 171, also is used to eject the retainer that is molded as.Above-mentioned pushing pin 4111 passes fixation side base plate 4140 and fixed bolster plate 4105, can slide, and above-mentioned core pin 41 09 is between these two pushing pins.Usually, the far-end of pushing pin 4111 forms the part of retainer molded indentation, in particular, can form the part of retainer 171 external structures, and, when fixation side reclaiming plate 4110 moved to the position of Figure 65, the far-end of these pushing pins just contacted with the retainer 171 that is molded as, and they are ejected.
Usually, mobile mould 4102 is arranged to and fixed die 4101 coaxial lines, and is connected with a driving mechanism (not shown), thus whole mobile mould can be between mold closed position and mold opened position the left and right directions along figure reciprocating.On mold closed position, mobile mould is close to fixed die 4101, and on mold opened position, two moulds are separated from each other.The support pattern of mobile mould 4102 makes it to rotate a predetermined angle around the axis (pivot center R) of oneself.In particular, mobile mould 4102 can rotate between mold position and rigging position.Be molded into housing 170 and retainer 171 on mold position, on the same axis line, the position (below will be described in detail) relative to each other in the position of rigging position (with mold position 180 degree of being separated by) housing 170 and retainer 171.
Mobile mould 4102 is the same with fixed die, comprises a mobile side installing plate 4112.Mobile side base plate 4142 is installed on the mobile side installing plate 4112 by cushion block 4150.Fore-and-aft direction moving die plate 4113 and 4141 separated from each other is bearing in the front side of mobile side base plate 4142.Be provided with a spring 4118 between two blocks of moving die plates 4113 and 4141, it pushes preceding moving die plate 4113 forward.
Two guide fingers 4106 are installed in the relative two ends of mobile side base plate 4142 respectively, pass two blocks of moving die plates 4113 and 4141, and outstanding to fixed die along axis direction.Closed and when opening at mould, guide finger 4106 inserts respectively in the fairlead 4114, thereby can be die sinking and mold closing motion guide.Housing molded indentation 4115 and retainer molded indentation 4116 all form on the surface of fixed die at preceding moving die plate 4113, usually, molded indentation 4115 is aimed at main core pin 4107, and molded indentation 4116 is aimed at the pushing pin 4111 of core pin 4109 and two molded retainer 171 usefulness.Open the gate (not shown) of leading to two molded indentations 4115 and 4116 respectively, so the resin of fusion just charges in these two molded indentations by corresponding gate.
In the present embodiment, when two moulds 4101 and 4102 closures, formed two die cavitys, the die cavity of the die cavity of a molded retainer 171 and a molded shell 170, be arranged on two circumference, the position at the center of these two circumference is on pivot center R (axis of mould).And the distance that these two die cavitys leave pivot center R equates, the angle of 180 degree of being separated by mutually.
On mobile mould 4102, between mobile side base plate 4142 and mobile side installing plate 4112, be provided with a pin plate 4117.This pin plate 4117 is connected with a driving mechanism (not shown), can be reciprocating along axis.Be used for the knock pin 4120 that the connector that housing 170 and retainer 171 is linked together ejects is installed in pin plate 4117, and parallel to the axis.The position of the far-end of knock pin 4120 flushes with the inner surface of housing molded indentation 4115 usually.But after housing 170 and retainer 171 linked together, when current pin plate 4117 advanced, the far-end of knock pin 4120 was just charged in the housing molded indentation 4115, and the connector that assembles is ejected.
The core pin 4119 of imbedding that is used for molded shell 170 is contained in back moving die plate 4141, and is parallel with axis.This is imbedded core pin 4119 and charges into the housing molded indentation 4115 from the mold position of housing 170 in predetermined operating process (shown in Figure 62-64), keeps step 182 so that be molded into.But,, when two blocks of moving die plates 4113 and 4141 leave mutually, withdraw from from housing molded indentation 4115 just this imbeds core pin 4119, thereby also just from molded good housing 170, withdraw from when shown in Figure 63.
The above-mentioned mould molded shell 170 and the molded work step of retainer 171 and the assembly process that they are linked together that adopt the tenth embodiment are described below.
Under the state of mould closure (Figure 62), moving die plate 4113 closely contacts mutually with fixed bolster plate 4105 before this moment, housing molded indentation 4115 is closed, form the space or the die cavity of a sealing, simultaneously, by two retainer molded indentations 4108 that on fixed die and mobile mould, form respectively and 4116 another enclosure spaces that defined, then become the die cavity of molded retainer 171.Under this state, the resin of fusion is charged in the die cavity of these two sealings by corresponding gate (not shown).Because main core pin 4107 and imbed core pin 4119 and all charge in the housing molded indentation 4115, so just formed the outer shape of housing and its internal structure (retraction space 176, keep projection 177 etc.).The die cavity of molded retainer 171 is formed by two molded indentations that match each other 4108 and 4116, and core pin 4109 is charged in this die cavity, thereby has formed the profile of retainer 171 and its internal structure (temporarily keeping pawl 183, linking arm 179 etc.).
Then, charge into the resin of fusion, when through the preset time hardening of resin, mobile mould 4102 is just return, and mould is opened, shown in Figure 63.After opening mould, housing 170 is stayed in the housing molded indentation 4115, and retainer 171 is then stayed in the retainer molded indentation 4108 of fixed die.In the course of action of die sinking, two mobile side templates 4113 and 4141 leave mutually under the effect of spring 4118, as mentioned above, just withdraw from from housing 170 so imbed core pin 4119.As mentioned above, imbed core pin 4119 and will be used for molded maintenance step 182 etc., if in the assembly process of back, imbed core pin 4119 and before retainer 171 and housing 170 couple together, from housing, do not withdraw from, assembly process will be adversely affected so.Therefore, this to withdraw from operation be necessary.
Then, shown in Figure 63, whole mobile mould 4102 rotates 180 degree around axis R, turns to rigging position from mold position.As mentioned above, housing 170 and retainer 171 are clamped in respectively on the circumference, and their center all is positioned on the pivot center R, and the angle of spaced-apart 180 degree.Therefore, when mobile mould 4102 rotated, the housing 170 that is molded as was relative with the retainer 171 that is molded as on same axis.
Then, the fixation side reclaiming plate 4110 in fixed die 4101 moves forward (seeing Figure 65), releases the retainer molded indentation 4108 that forms so the retainer 171 that is molded as is pushed untie-sell 4111 in fixed die, and moves to retainer 171.At this moment, core pin 4109 is withdrawn from from retainer 171.This core pin 4109 is used for forming temporary transient maintenance pawl 183 members such as grade, if it is not withdrawn from from retainer 171 before retainer 171 and housing 170 couple together, will adverse influence be arranged to assembly process.Retainer 171 was packed into housing 170 by pushing pin 4111 before, core pin 4109 and 4119 had just all been withdrawn from, and therefore, did not influence temporary transient maintenance pawl 183 fully and kept being connected of step 182.Like this retainer 171 just and housing 170 linked together.
Then, after fixation side reclaiming plate 4110 was got back to the home position, the connector that housing 170 and retainer 171 are linked together then shown in Figure 66, was still stayed in the mobile mould.Then, pin plate 4117 moves forward, and knock pin 4120 promotes housing 170, so the connector that is in confined state (temporary transient hold mode) is pushed out housing molded indentation 4115, falls down from mould.After connector took out, pin plate 4117 was got back to the home position, and mobile mould 4102 is to turning to the home position in the opposite direction with above-mentioned side.Like this, two moulds 4101 and 4102 have all been got back to their corresponding home positions, for next molding process ready.
As mentioned above, in the present embodiment, the work step of molded shell 3 and retainer 4, and the assembling work step that they link together carried out at the same time, therefore, just do not needed independently conveying in the conventional method and assembling work step, and because technical process has shortened, product has also shortened from the time that is dosed into out finished product.Simultaneously, manufacturing cost has also reduced.
In addition, in the present embodiment, as long as the operation pushing pin just can link together housing 170 and retainer 171.It is also conceivable that and utilize the mould closing course to realize assembly process.But in this case, those parts that move are very big, and energy needed is just many.On the other hand, in the present embodiment, those parts that will move are forced down minimum degree, and simple in structure, and the operation energy needed is few.
In addition, because different types of molded products, i.e. housing 170 and retainer 171, can be in a mould molded come out from mold management, also is very favourable.In addition, in the present embodiment, core pin 4109 and 4119 had just been withdrawn from respectively from retainer 171 and housing 170 before implementing assembly process, therefore helped these two parts are successfully linked together.
