DESCRIPTION THE PREFERRED EMBODIMENTS

The 1 and 2 FIG. 15 are perspective views of a synthetic resin molding assembly, for the production of which a metal molding apparatus and a resin molding method manufacturing method according to a first embodiment of the invention are provided.

In the figures, there is the resin molded part assembly (a connector) 10 from a housing 20 in the form of a cuboid and holding parts 30a and 30b , which are U-shaped in cross-section and to the top and bottom of the housing 20 are attached. The housing 20 is with reception chambers 21 provided for cylindrical metal connection sockets, wherein the chambers perform from back to front and two are provided on an upper level and four at a lower level. The upper level chambers are formed on the left and right sides of the housing, and in the middle there is an upwardly and downwardly flexible locking arm 22 , The outer shape of the part from the middle to the back of the case 20 has smaller size than the front end. Each reception room 21 for the metal connection sockets is with an opening 21a which points adjacent to the front end of the narrower part upwards and downwards.

To the holding parts 30a and 30b , which is U-shaped in cross-section to attach to the narrower part of the top and bottom, are a total of four guide rails 24 , which are formed like a rib, integrally formed on both side surfaces in association with the upper holding part and the lower part. The guide rails 24 extend obliquely toward the vertical center toward the front end respectively on the side surface. The cross section of each upper guide rail 24 is provided with an upwardly facing slope and the cross section of each lower guide rail 24 is provided with a wedge-shaped, down-facing slope.

A small lead 25 is further forward in an extension of the guide rail 24 formed. Further inward from the guide rail 24 and the small lead 25 out there is an ejector bar 26 which is parallel to the inclination of the aforesaid parts and protrudes to the same width as the front part of the housing. The upper ejector bar 26 and the lower ejector bar 26 are connected to each other at the front and together form a shape corresponding to the letter V.

The holding parts 30a and 30b as a whole are symmetrical overall and when U-shaped openings after the housing 20 are provided, then take the cheeks 31 the narrower part of the case 20 from both sides. The cheek 31 is with a guide groove 32 which have a width having, which allows the same inclination guide rails 24 and the little projections 25 can intervene there. The lower end of the cheek 31 runs obliquely, making it along the V-shaped ejection strips 26 runs.

The holding parts 30a and 30b are shorter than the narrower section of the housing. If therefore the holding parts 30a and 30b to the housing 20 be attached to the housing between them 20 pick up from the top and bottom, then grip the guide rails 24 in the grooves or grooves 32 one and can be moved obliquely in them backwards and forwards, leaving the holding parts 30a and 30b in turn, in the backward movement and the forward movement of the housing 20 be moved or moved towards this. The small projections 25 enter the grooves or grooves 32 at the front ends of the range of motion. The holding parts 30a and 30b even within their range of motion are not backward over the rear end of the housing 20 above.

The upper holder part 30a and the lower holding part 30b are with two or four projections 33 provided, which at positions which the openings 21a at the housing part 20 facing inner surface, in the openings 21a can reach into it. The projections 33 are formed edge-shaped and project in the forward direction, so that they lock on an inner metal connection socket (not shown) to prevent the removal, if the corresponding projection 33 in the associated receiving chamber 21 for the metal connection socket. If the holding part 30a respectively 30b is moved backwards and forwards and at the front end of the housing 20 approaches the most, as described above, then the projections occur 33 into the receiving chambers for the metal connection sockets over the openings 21a one. If the metal connector is in the semi-inserted state, then the projection is 33 on the end face of the metal terminal to move it to the proper insertion position. Grooved recesses 35 are on the opposite surface of the projections 33 trained and have a wider depth with progressive depth Unterschneidungsgestalt. cuts 34 and 34 are at the root of the cheeks 31 and 31 provided so that the roots of the cheeks 31 and 31 made more flexible.

The 10 and 11 are sectional views showing how the holding parts 30a and 30b make a double lock. A synthetic resin tongue 27 is at the bottom of each receiving chamber 21 for the metal connection sockets in the housing 20 cast in one piece and molded. If a metal connector 40 is used, then enters a projection 27a the on the upper surface of the resin tongue 27 is formed in a locking hole 41 one in the bottom of the metal connector 40 is provided and locked in it (primary interlock). At this time are the holding parts 30a and 30b positioned at the rear end in the range of motion and no projection 33 enters the receiving chamber 21 for the metal connection sockets.

If next, the holding parts 30a and 30b are moved toward the front end, they approach the housing 20 on and the projections 33 enter the receiving chambers 21 for the metal connection sockets over the openings 21a and lock on the metal sockets 40 (secondary lock). The state in which the holding parts 30a and 30b in the rearward end position is to be referred to as a provisional locking state, and the state in which the holding parts 30a and 30b in the front end position is to be referred to as a complete locking state.

3 On the other hand, Fig. 15 is a front view of a movable mold of a metal mold for producing the resin mold assembly 10 , The mobile form 100 , which is shown in the drawing figure, forms a pair of parts with a fixed shape 200 , which is arranged with respect to the plane of the drawing on the front. As shown in the drawing figure, there is the movable shape 100 from housing shapes (movable pins) 110 and 110 , which are upwardly and downwardly displaceable and allow the housing 20 to pour on the inner surface side, as well as holding part forms (assembly push pins) 120 and 120 , which on the left and the right side of the housing forms 110 and 110 are displaceable in the horizontal direction. The housing forms 110 . 110 form the outer surface of the cheeks 31 . 31 the holding parts 30a and 30b in the part of the holding part forms 120 . 120 is facing and coming into contact with them. Part of the established form 200 enters a space through the housing shapes 110 . 110 and the holding part shapes 120 . 120 for casting the holding parts 30a and 30b is surrounded. For this reason, on the inner surface side of the holding part molds 120 . 120 in a simple manner thereby formed a space, so that the fixed shape 200 is pulled out. That is, for a plurality of synthetic resin castings assembled for assembly, the opposite side surface of a synthetic resin casting is formed with respect to its mating matching synthetic resin casting without a slide pin, thereby simplifying the structure of the metal mold.

In the embodiment, the to the holding parts 30a and 30b on the housing 20 opposite surface also by the up and down sliding housing forms 110 . 110 cast, but the molding can also be on the side of the fixed mold 200 done, in which case the opposite surface between the housing 20 and the holding parts 30a . 30b can be easily shaped by the fixed shape 200 is pulled out and a space for moving the holding parts 30a and 30b by opening the fixed mold 200 and the movable form 100 can be formed. As a result, the metal mold can be made simpler in structure. In the present embodiment, the housing shapes are 110 and the holding part mold 120 , which are sliding pins, in the movable mold 100 but they can also be in the fixed form 200 be held.

As described above are in the holding parts 30a and 30b in the areas which the projections 33 opposite, undercut recesses 35 trained and the holding part forms 120 . 120 are with projections for the formation of the recesses 35 Mistake. The respective projection is on the side of the holding part forms 120 formed, the housing forms 110 . 110 facing, and the holding parts 30a and 30b are formed with their undercut part in this direction. Accordingly, they do not fall on the side of the package shapes 110 . 110 down.

The holding part forms 120 . 120 do not extend over the entire width of the holding parts 30a . 30b and cheeks 31 . 31 at both ends of the holding parts 30a . 30b lie outside the holding part forms 120 . 120 , This means the holding part shapes 120 . 120 press the holding parts 30a . 30b against the case 20 at positions outside the cheeks 31 . 31 which form bending parts when the holding parts 30a . 30b for assembly with the housing 20 be joined together.

The 4 to 6 Fig. 3 are schematic drawings which illustrate how the slidable pins or dies are in the movable mold 100 move. These are only schematic views, with no correspondence to details of the resin mold assembly 10 given is.

The housing forms 110 . 110 and the holding part shapes 120 . 120 move in such a way that they attach themselves to the core in the middle of the movable mold 100 approach or move away from it. As in the 7 and 8th is shown, the housing forms 110 . 110 with oblique through holes 111 . 111 provided, in which oblique pins 210 . 210 can be introduced so that they are different from the solid form 200 to the movable form 100 extend. If the fixed shape 200 and the movable form 100 approach each other or remove from each other to be fixed for the casting or to open, then approach the housing forms 110 . 110 to each other or separate from each other. The diameter of the passage openings 111 . 111 is larger in the longitudinal direction than that of the slanted pins 210 . 210 , whereby it is achieved that the time to which the movable form 100 and the established form 200 opened, and the time to which the housing forms 110 . 110 be opened, can be made different. In the present embodiment, the opening of the housing molds 110 . 110 a short time after the start of the opening of the movable mold 100 and the established form 200 started.

On the other hand, for the holding part shapes 120 . 120 , as in 9 shown a reset drive rod 220 which from the side of the fixed form 200 protrudes and has an inclined surface at its tip, and an engaging drive rod 230 provided which protrudes from the side of an ejection punch (not shown) and has an inclined surface which is at its tip on the opposite side with respect to the return drive rod 200 is provided, wherein the return drive rod and the engagement drive rod in sliding contact with a cam 121 can come, which has an inclined surface, and at the end of the holding part mold 120 is trained. The two drive rods 220 and 230 are operated at different times, so that the holding part shape 120 is moved back and forth.

Next, be a method of manufacturing the resin molding assembly 10 of the structure described by means of the metal-forming device of the previously discussed construction considered closer.

At the beginning are in the movable form 100 the housing shapes 110 . 110 in intimate contact with each other and the holding part shapes 120 . 120 are in close contact with each other on both sides. The established form 200 is in intimate contact with the front of the movable mold 100 and protrudes to the insides of the receiving chambers 21 for the metal connection sockets and to the inner surface areas of the holding parts 30a and 30b before, wherein the projections in 5 are schematically indicated by dash-dotted lines. When the metal mold is filled with molten resin, the resin becomes between the fixed mold 200 and the movable form 110 as in 4 shown hardened. If the fixed shape 200 and the mobile one shape 100 after curing opens, the tilted pins run 210 against the inner peripheral surfaces of the through holes or through holes 111 the housing forms 110 with a slight delay relative to the opening of the fixed mold 200 and the movable form 100 and arrive from the area of the passage openings 111 , Consequently, the housing shapes open 110 . 110 relative to each other, as in the 5 and 8th is shown. At this time, recesses and protrusions which are in a direction perpendicular to the mold opening direction engage in the housing shapes 110 and the holding part shapes 120 are provided on the slidable punches, so that the housing 20 and the holding parts 30a and 30b at the moving shape 100 be held as in 5 is shown.

When the case shapes 110 . 110 by the sliding movement between the slanted pins 210 and the passage openings 111 at the mold opening step of the fixed mold 200 and the movable form 100 then the housing will be opened 20 released on its top, bottom, left and right surfaces and on the front surface. On the other hand, if the fixed shape 200 from the movable form 100 is pulled out, then the inner surfaces of the holding parts 30a and 30b , which in the holding part forms 120 . 120 are left, completely uncovered and the holding parts 30a and 30b are held so that they face each other to the right and to the left, leaving them between them the housing 20 frame. At that time, the recesses prevent 35 , which in undercut form on the holding parts 30a and 30b are provided that these fall down in the released space.

Thereafter, when the drive of the ejector pin is started, the bevel shifts at the tip of the engagement drive rod 230 the skew of the cam 121 the holding part forms 120 and the holding part shapes 120 become the case 20 moved. The holding parts 30a and 30b be against the top or the bottom of the housing 20 pressed with facing opening of the U-shape, wherein the holding parts 30a . 30b , as in 6 is shown on the holding part forms 120 are held. If the left cheek and the right cheek 31 respectively 31 each holding parts 30a . 30b the narrow part of the case 20 approaching, so that this housing part comes to lie between the cheeks, then run the end surfaces of the cheeks 31 against the guide rails 24 at. The cheeks 31 which are wedge-shaped in cross-section, as described above, ride over the guide rails 24 path. When the guide rails 24 in the guide grooves or guide grooves 32 the cheeks 31 intervene properly, then the holding parts 30a and 30b on the case 20 established. The assembly of this parts association is now complete. When the ejector pin is driven, the assembly is fully assembled and as the ejector pin continues to be driven, the housing becomes 20 , which with the holding parts 30a and 30b has been joined together, from the movable mold 100 away. As for the projections 35 no undercut is provided in the direction of ejection, an economically feasible removal or removal may be provided.

The mobile form 100 consists of the sliding housing forms 110 . 110 and the sliding holding part shapes 120 . 120 , and the established form 200 , which of the movable form 100 is assigned, is used for casting the housing 20 and the holding parts 30a and 30b with synthetic resin at the same time. The established form 200 and the movable form 100 are opened and the housing shapes 110 . 110 the sliding forming dies are opened. While a space between the case 20 and the holding parts 30a and 30b which are to be put together become the holding parts 30a and 30b against the case 20 pressed, with the holding parts 30a and 30b at the holding part forms 120 . 120 held to the right and left sides, leaving the case 20 and the holding parts 30a and 30b can be assembled. The recesses 35 an undercut form will be in the holding parts 30a and 30b by means of the projections of the holding part molds 120 . 120 formed, and the recesses and projections are engaged with each other so that they prevent the holding parts 30a and 30b fall into the released space or fall into a misplaced position.

The holding part forms 120 . 120 press the holding parts 30a and 30b in positions outside the cheeks 31 which are bending parts, so that these areas outside the holding part shapes 120 . 120 also turn and cheeks 31 open like a funnel for easy access.

The cheeks can continue 31 due to the notches 34 slightly bent, in the foot area or at the root of the cheeks 31 are formed. The cheeks run on the guide rails 24 and open like a funnel. As a result, the cheeks ride 31 without breakage over the guide rails 24 away and the guide rails 24 back into the guide grooves 32 the cheeks 31 for the preparation of the procedure.

The holding parts 30a and 30b protrude beyond the rear end surface of the housing 20 not out. If the case 20 is taken from the metal forming device, so Ends even if on the holding parts 30a or 30b a blow works, one Movement from the provisional locking position to the full locking position does not take place.

In the present embodiment, the housing shapes become 110 and the holding part shapes 120 in mechanical coupling with a movement of the fixed shape 200 and the movable form 100 and a movement of the ejector pin or ejection punch moves, but it can also be provided by a drive by hydraulic or compressed air or a motor. The space between the resin molded parts can be created not only by opening the mold and linearly moving the slidable dies or pins, but also by a two-dimensional or three-dimensional driving operation. Further, a plurality of slidable dies may co-move the resin moldings.

When next Let the operation of a metal-forming device according to a second embodiment discussed.

26 shows a state which is a movable shape 100 the metal mold device for producing a synthetic resin casting assembly 10 in front view to allow easy understanding of a sliding mold movement. The mobile form 100 , which is shown in the figure, acts with a fixed shape 200 together, located with respect to the drawing plane on the front. As shown in the figure, there is the movable shape 100 from housing forms (movable forming dies) 110 . 110 which are displaceable to the right and to the left and are capable of housing 20 on their inner sides, as well as holding partial forms (sliding assembly pencils or stamps) 120 . 120 in vertical directions on the top and bottom of the housing shapes 110 . 110 , are displaceable.

On the other hand shows 27 Conditions of the mobile form 100 and the established form 200 during a shape fixation in cross sections by changing the directions; the 27 shows sections from the three directions for easier understanding of the relationship between the horizontal and vertical directions. ie 27A shows the axial cross section; 27B shows the vertical cross section; and 27C shows the horizontal cross section.

The established form 200 contains a mounting plate 210 , a mold plate 220 and an upstream removal plate 230 which are superimposed with respect to each other. The mounting plate 210 and the upstream removal plate 230 can in one piece from the mold plate 220 be separated and are movable. A core pin 211 and sliding pins 212 , which on the mounting plate 210 are attached, pass through the mold plate 220 and are in the mold cavity of the resin casting assembly 10 used. Next are on the mounting plate 210 first cam pins 213 . 213 , as well as second cam pins 214 . 214 for driving the housing forms 110 . 110 and the holding part shapes 120 . 120 attached. They reach through the mounting plate 210 and the mold plate 220 and engage in the cam passages 111 . 111 and the cam openings 121 . 121 , which in the housing forms 110 . 110 and the holding part shapes 120 . 120 are provided. The tips of the first cam pins 213 and the second cam pins 214 are bent or curved. The cam openings 111 and 121 are configured to allow a sliding drive movement in a predetermined direction when the curved tips of the first cam pins 213 and the second cam pins 214 pass through. As in 27 is shown grip during the fixing of the first cam pins 213 . 213 , and the second cam pins 214 . 214 through the cam holes. 111 . 111 and the cam openings 121 . 121 , with their linear sections. The tips of the first cam pins 213 . 213 are outwardly curved and the tips of the second cam pins 214 . 214 are curved inwards.

The mobile form 100 contains a mounting plate 130 , a mold plate 140 and protruded plates 150 , which lie one above the other. The mold plate 140 and the mounting plate 130 are fixed in a relatively immovable position, while between them the projections provided with plates 150 are held displaceable. A projecting pin (not shown) is on the projected plates 150 held to be used when the finished resin castings are removed from the metal forming device.

Next, be a method of manufacturing the resin molding assembly 10 of the above-described structure by means of the metal former according to the discussion discussed above.

At the beginning are in the movable form 100 the housing shapes 110 . 110 in intimate contact with each other, and on both sides are the holding part shapes 120 . 120 in positions to form the holding part mold cavities. The established form 200 is in intimate contact with the front of the movable mold 100 and the core pin 211 and the movable pins 212 protrude into the receiving chambers 21 for the metal connection sockets and in the inner surface areas of the holding parts 30a and 30b , If the metal formein filled with molten synthetic resin, the resin solidifies between the fixed mold 200 and the movable form 100 , After solidification, the separation of the mounting plate begins 210 and the advance removal plate 230 the established form 200 from the mold plate 220 without an opening of the mold plates 220 and 140 the established form 200 or the movable form 100 ,

If the separation of the mounting plate 210 from the mold plate 220 starts, come first the core pin 211 and the sliding pins 212 from the interiors of the receiving chambers 21 for the metal connection sockets and from the inner surface areas of the holding parts 30a and 30b out. The sliding pins 212 move out of the inner surface areas of the holding parts 30a and 30b , creating a space within the inner surface areas of the holding parts 30a and 30b is formed. At the same time, the first cam pins are also slidingly displaced 213 . 213 and the second cam pins 214 . 214 , The rectilinear sections of the second cam pins 214 . 214 only glide within the cam holes 121 . 121 in the holding part molds 120 . 120 , Are provided and the holding part forms 120 . 120 so do not move. The outer curved portions of the tips of the first cam pins 213 . 213 but run through the cam openings 111 . 111 , which in the housing forms 110 . 110 are formed, whereby the two housing forms 110 . 110 to be moved outwards, as in 28 and 29 is shown. The housing forms 110 . 110 glide outward, creating a space between the holding parts 30a and 30b and the housing 20 becomes free, as in 28 is shown.

If thereafter the mounting plate 210 further from the mold plate 220 is separated, the outwardly curved portions of the tips of the second cam pins wander 214 . 214 through the in the holding part forms 120 . 120 formed cam passage openings 121 . 121 , whereby the two holding part forms 120 . 120 glide to the inside, where the case 20 located. The holding parts 30a and 30b be against the top or the bottom of the housing 20 with the pressed against this opening U-shape, with the holding parts 30a and 30b at the holding part forms 120 . 120 are held. If the right cheek and the left cheek 31 . 31 each holding parts 30a . 30b cause it to stick to the narrow part of the case 20 so that they enclose this part between themselves, then the end faces of the cheeks run 31 against the guide rails 24 at. The cheeks 31 , which are wedge-shaped in cross section, ride over the guide rails 24 , When the guide rails 24 in the guide grooves 32 the cheeks 31 enter and engage, are the holding parts 30a and 30b with the housing 20 engaged. The assembly is now complete, as in the 30 and 31 is shown.

When the holding parts 30a and 30b against the top or bottom of the housing 20 be pressed, with the holding parts 30a and 30b at the holding part forms 120 . 120 are fixed, are the fixed form 200 and the movable form 100 in a mold fixing state and the holding parts 30a and 30b do not fall from the holding part shapes 120 . 120 from.

If after that the established form 200 and the movable form 100 opened and the tabbed plates 150 the movable form 100 sliding, the housing becomes 20 on which the holding parts 30a and 30b are attached, from the movable mold 100 away.

Thus, the movable form 100 , which from the sliding housing forms 110 . 110 and the holding part shapes 120 . 120 exists, and the established form 200 which with the movable form 100 cooperates, used to the housing 20 and the holding part 30a and 30b to be cast simultaneously from synthetic resin. The mounting plate 110 and the upstream removal plate 230 in the fixed form 200 be from the mold plate 220 during the form fixation separately. While between the case 20 and the holding parts 30a and 30b which are put together, a space is created, the holding parts 30a and 30b against the case 20 pressed down, with the holding parts 30a and 30b at the holding part forms 120 . 120 held on the right and left sides, eliminating the housing 20 and the holding parts 30a and 30b be assembled. Because they are assembled during the mold fixing when the holding parts 30a and 30b are moved, there is no danger that they fall down.

In the present embodiment, the housing shapes become 110 and the holding part shapes 120 moved in mechanical coupling with a movement of the cam pins, but can also be driven by hydraulic, compressed air or by a motor. The space between the resin molded parts can be created not only by an opening of the mold and a linear movement of the sliding pins, but also by a two-dimensional or three-dimensional driving movement can be generated. If the fixed shape continues 200 and the movable form 100 each of them can be moved for the opening of the mold or both can be moved simultaneously.

In the present embodiment who the two pairs of cam pins 213 and 214 in the solid form 200 used. The 32 to 34 show a modified embodiment, which third cam pins 131 . 131 for moving the holding part molds 120 . 120 a movable form 100 instead of the second cam pins 214 . 214 the solid form 200 shows. The third cam pins 131 . 131 are on a first projection plate 150a in a solid form 200 attached. They pass through a mold plate 140 and engage cam lobes 121 . 121 in the holding part forms 120 . 120 a, like in 32 is shown.

Next will be a mounting plate 210 and an upstream removal plate 230 from. a mold plate 220 in the solid form 200 separated and the housing shapes 110 . 110 open to the left and to the right as in 33 is shown. Before opening the solid form 200 and the movable form 100 becomes the first projection plate 150a advanced and the holding part forms 120 . 120 be through the third cam pins 131 . 131 moves, as in 34 is reproduced. This has the consequence that a connector 10 as can be assembled in the previously discussed embodiment.

In the first embodiment, the movable mold 100 and the ejector pin driven by different drive sources. When the movable form 100 is designed so that it moves backwards and forwards between the solid form 200 and can move the ejector pin, it follows that in their backward movement of the ejector pin moves relatively forward.

In the embodiment described above, the holding part shape becomes 120 returned to the initial position by the return drive rod coming from the fixed mold 200 projecting. If the case 20 on which the holding parts 30a and 30b are attached, from the movable mold 100 is removed, and then a shape fixing is performed, the return drive rod comes into sliding contact with the cam 121 which has a bevel at the end of the holding part mold 120 is formed, and moves them. Therefore, if the case 20 is moved by the ejector pin, the holding part shapes remain 120 on the case 20 advanced.

In the first and second embodiments, the housing 20 not wider than the holding parts 30a and 30b , and if the holding part shapes 120 on the case 20 remain advanced, no damage occurs. However, if the case 20 wider than the holding parts 30a or 30b, offers the holding part shape 120 an obstacle when the housing is driven by the ejector pin.

The 12 to 17 show a third embodiment of the invention, this embodiment prevents the holding part shapes 120 . 120 stay advanced when the case 20 Will get removed. In the third embodiment, to drive the housing shapes protrude 110 and the holding part shapes 120 which is displaceable on a movable mold 100 are held like this in 13 shown is two cam parts or pins 211 and 212 which work in a similar way as the angled pins 210 in the first embodiment, of a fixed shape 200 away, and sliders 112 and 122 through which the cam parts or cam pins 211 and 212 protrude through, are in the moving form 100 arranged.

The housing forms 110 . 110 are with the sliders 112 . 112 coupled, which is displaceable on the outer sides opposite the housing 20 are stored, and the short cam parts or cam pin 211 pass through the sliders 112 and 112 therethrough. As with the angled pins 210 if the moving form 100 from the solid form 200 is separated, the sliders 112 and 112 driven outwards and the housing shapes 110 . 110 are driven so that they open. If, on the other hand, the movable mold 100 and the solid form 200 be made to a mutual approach, the sliders 112 and 112 driven inward and the housing shapes 110 . 110 are driven so that they open. Also in this case is like the angled pins 210 provided a game and the housing shapes 110 . 110 open with a slight delay to the mold opening time when the moving mold 100 from the solid form 200 is disconnected.

Two sliders 122 . 122 are arranged so that the slider 112 on a housing shape 110 between them lies and long cam parts or cam pins 212 . 212 pass through the sliders 122 . 122 , The long cam part or pin 212 . 212 has longer length in the straight part than the short cam parts or pins 211 . 211 , As a result, the time of movement of the sliders 122 different from the time of movement of the sliders 112 becomes.

Coupled with the slides 122 . 122 are holding part cam parts 123 . 123 , which are parallel to the direction of movement of the housing forms 110 . 110 extend and the holding part shapes 120 . 120 frame on both sides. As in 14 is shown, stands each holding part cam part 123 . 123 with the rear surface of an associated holding part mold 120 . 120 in touch. That is, the holding part cam part 123 and the holding part mold 120 have facing mountain-like projections, and when the holding part-cam part 123 moved back and forth, then presses a skew the holding part shape 120 against the case 20 ,

If the holding part shape 120 only pressed, it remains on the housing 20 advanced. The holding part form 120 contains however a plate part 124 projecting in such a way that it is with the holding part cam part 123 overlaps. A lead 124a protrudes toward the holding part cam part 123 and is on the plate part 124 provided, and a V-shaped Leitkulissennut 123a into which the lead 124a is engageable in the holding part cam part 123 intended. The Leitkulissennut 123a substantially corresponds to the mountainous projection of the holding part cam part 123 , and the holding part form 120 caused by the inclination of the holding part cam part 123 is pushed out through the into the Leitkulissennut 123a protruding projection 124a retracted when the holding part cam part 123 is moved further sliding. This means, every time the holding part cam part 123 moving to one side makes the holding part shape 120 a float. This has the consequence that after the opening of the housing forms 110 . 110 the holding part forms 120 . 120 to the case 20 approach while holding the holding parts 30a and 30b Keep this against the case 20 press to engage with the housing, after which the holding part shapes return to their original positions. Therefore, if thereafter the ejector pin the housing 20 pushes out from the back, the housing ejector pin does not run on the holding part shapes 120 . 120 at. A spring (not shown) is between the movable mold 100 and the holding part shapes 120 . 120 arranged to the holding part shapes 120 . 120 in the opening direction to prevent play.

Incidentally, it should basically be said that if the holding part form 120 only moving back and forth, it would be enough, only the lead 124a and the Leitkulissennut 123a to use in cooperation. In the present embodiment, however, the holding part cam part 123 and the holding part mold 120 provided with facing bergartigen or hill-like slope and the bevels are used for pushing out. If the holding part shape 120 is driven after opening the mold, sometimes a large force may be required, so that it is appropriate to apply the cam bevels together to the holding part shape 120 drive. The holding part form 120 can then be withdrawn by a small force and serve for this purpose the projection 124a and the Leitkulissennut 123a , The construction can therefore be suitably changed in such a way that for driving the holding part mold 120 depending on the size of the required force no inclinations are provided. The position to which the holding part shape 120 is not necessarily the initial position and may be any position in which the holding part shape 120 pushing out the case 120 not disabled.

In the embodiment, a space is formed between the housing 20 and the holding parts 30a and 30b by opening the movable mold 100 and the solid form 200 and moving the housing shapes 110 . 110 so that these movements correspond to a structure with a fifth forming motion, however, it goes without saying that the invention is not limited to such a structure. While the holding part cam parts 123 . 123 Slidably moving, the holding part shapes move 120 . 120 relative to the housing 20 back and forth, with the holding parts 30a and 30b at the holding part forms 120 . 120 are held so that the components here form a structure for a sixth forming movement. The structure for a sixth forming motion does not require a separate drive source when it is a cam mechanism coupled to the mold opening, but a separate drive may be provided using a drive source such as a hydraulic or a pneumatic drive or an electric motor.

The eighteen to 21 For example, show a modification of the embodiment in which an actuating drive of a feed mechanism is used for driving and holding part cam parts 123 are arranged parallel to the mold opening direction.

A mobile form 100 contains a mold plate 140 , which of the solid form 200 is facing to the housing shapes 110 . 110 and the holding part shapes 120 . 120 support, a mounting plate 150 , which are at a certain distance from the mold plate 140 is arranged and on the back of the mold plate 140 located, as well as a first projection plate 160 and a second protrusion plate 170 which is displaceable in both directions between the mold plate 140 and the mounting plate 150 are guided. For the interaction structure of the holding part mold 120 with the holding part cam part 123 as they are in 19 is shown, since the sliding direction of the holding part cam member 123 becomes parallel to the mold opening direction, the holding part shape 120 as a whole turned 90 °, and if the holding part cam part 123 through the mold plate 140 reaches and moves backwards and forwards, the holding part shape goes 120 in a similar way as described above. In the drawing figure, the support structure of the mold plate 140 and the mounting plate 150 Not shown.

The holding part cam parts 123 protrude through the mold plate 140 to the mounting plate 150 before and are on the second projection plate 170 through the first projection plate 160 attached leading through. The second projection plate 170 is on a piston 181 a feed actuator 180 attached, this piston through the mounting plate 150 passed through. When the actuator drive 180 from a hydraulic source (not shown) is pressurized oil and the piston 181 moved backwards and forwards, then moves the second feed plate 170 parallel between the mold plate 170 and the mounting plate 150 back and forth.

On the other hand, a Ausschubstift 161 on the first feed plate 160 fastened, through which the holding part cam parts pass 123 extend, and is in a rear mold opening on the back of a housing 20 in the mold plate 140 introduced. The first feed plate 160 is about springs 162 on the mold plate 140 supported. The first feed plate 160 gets through the springs 162 to the side of the mounting plate 150 biased and is held by a stop (not shown) at a predetermined distance. Although the first feed plate 160 from the second feed plate 170 normally held at a distance, becomes the first feed plate 160 if the second feed plate 170 through the piston 181 is driven and at the rear surface of the first feed plate 160 is pending, in turn, towards the mold plate 140 driven and pushes the ejector pin 161 in the molded opening of the housing 20 to eject this. A passage opening 164 is in the first feed plate 160 provided and a spring 163 extends through the passage opening 164 through and find in her recording. The feather 163 clamps the second feed plate 170 in one direction from the mold plate 140 away before.

After the moving form 100 and the solid form 200 open, the piston becomes 181 the feed drive 180 according to the in 20 shown schedule pressed. That means the piston 181 shifts forward at a time A by half a working stroke. The half stroke corresponds to a distance that is sufficient to the holding part cam parts 123 inside the mold plate 140 be advanced so that the holding part forms 120 are moved, so that the upper holding part shape and the lower holding part shape 120 to move back and forth, reducing the holding parts 30a and 30b with the housing 20 be assembled so that the assembly takes place as in 21 shown. The second feed plate 170 is at the back of the first feed plate 160 after half the working stroke of the piston 181 at.

At the next time B, the piston shifts 181 for another half working stroke forward. Then the second feed plate moves 170 forward while in abutment with the first feed plate 160 remains, leaving the first feed plate 160 also advances. At this time, the ejector pin slides 161 that is attached to the first feed plate 160 is fastened, in the interior of the mold cavity for the housing 20 before, so that the assembled connector 10 is ejected, as in 22 is shown. At this time, the holding part cam parts shift 123 in a state in which they pass through the mold plate 170 rich, but they do not drive the holding part shapes 120 at.

The piston 181 shifts back by half a working stroke at a time C, and at the time D moves again and travels back by a full stroke at time E. Actually, the connector should 10 be ejected once the ejector pin 161 has advanced, but it may happen that he does not fall down. When the piston 181 In such a case, moving back to a full stroke, the holding part forms 120 against the connector 10 driven forward in the middle and then move back again. The holding part forms 120 hit on certain parts of the connector 10 so that these parts break. To avoid this malfunction, the ejector pin 161 repeatedly advanced into the area in which the holding part forms 120 then not be driven, even if the holding part cam parts 123 move to reliably the connector 10 throw off before the piston 181 completely moved back.

Although in the present embodiment, the ejector pin 161 Moved only twice, but it can be moved more than twice to achieve reliable ejection. Because the ejector pin 161 and the retainer cam parts 123 can be moved according to a predetermined schedule, they need not necessarily by an actuator drive 180 be moved and separate drive sources can be provided. Further, for example, a shaft of an electric motor can be provided with a rotating cam and by rotating drive a continuous drive of the ejector pin 161 and the holding part cam parts 123 effect, without an intermittent drive is provided for these parts.

Furthermore, the show 23 to 25 a modified embodiment in which the front and rear positional relationship between the second feed plate 170 for holding the holding part cam parts 123 , and the first feed plate 160 for holding the ejector pin 161 is turned around.

In the modified embodiment is on Position of the actuating drive 180 and the piston 181 , an ejector drive 184 provided that part 182 small diameter at the top and a part 183 having a large diameter at the rear end. The ejector drive 184 is at the rear surface of the second feed plate 170 via a passage opening 165 in the first ejection plate 160 at.

If the ejector drive 184 pushes inward, only the smaller diameter portion 182 through the passage opening 165 and only presses against the second feed plate 170 , From the point in which about half a stroke is exceeded, meets the larger diameter portion having 183 on the edges of the passage opening 165 in the first feed plate 160 and now also pushes the first feed plate 160 in front.

A fourth embodiment will now be described with reference to FIG 35 discussed. As described above in connection with the explanation of the previous embodiments, the holding part shapes 20 moved, whereby the holding parts are moved to assemble with the housing for assembly.

In the fourth embodiment, as in 35 shown when the holding part forms 120 . 120 for moving the holding parts 30a and 30b be moved, the holding part shapes parallel to a side surface 130 moved along the direction of movement, the side surface 130 on a movable mold 100 is formed, and at this time, the holding parts move 30a and 30b while on the side surface 130 slide.

When the holding parts 30a and 30b in the holding part forms 120 . 120 are held and, as in 35 shown to move, this movement occurs while the holding parts on the side surface 130 slide, causing the sides of the holding parts 30a and 30b , which of the sliding surface 130 are facing, held parallel and the holding parts 30a and 30b be transported to a housing, without being tilted.

If the left and the right cheek 31 each holding parts 30a . 30b approach the housing so that they form a narrower part of the housing 20 between them, then hit the end faces of the cheeks 31 on the guide rails 24 , Because the cheeks 31 wedge-shaped in cross-section, they slide over the guide rails 24 , When the guide rails 24 in the guide grooves 32 the cheeks 31 enter and engage, come the holding parts 30a and 30b with the housing 20 engaged. The assembly is then completed.

A fifth embodiment will now be described with reference to FIGS 36 and 37 discussed.

In the fifth embodiment, as in 36 and 37 shown, a projecting part 122 that with a wall surface 140 on the depth of the moving mold 100 comes into contact, at the top of each holding part form 120 formed so that a step-like level difference is formed. A holding part 30a ( 30b ) comes into contact with a stereoscopic surface of a corner of the step-like projecting part 122 and is kept in place. As in 37 is shown, the holding part at a distance from the adjacent wall surface 140 guided.

If the holding part 30a ( 30b ) in the holding part mold 120 . 120 is held, and, as in 37 shown, moved, it moves freely over the surrounding wall surface 140 , so that shaving off the holding part 30a ( 30b ) do not occur. For this reason, deterioration of the shape accuracy due to scraping, dust and the like can be prevented. The holding part 30a ( 30b ) comes in contact with the stereoscopic surface of the corner at the front of the holding part mold 120 . 120 and the side surface of the protruding part 122 and is held so that canting hardly occurs as compared with the case where the part is in contact with and held by a surface. For this reason, the holding part 30a ( 30b ) are prevented from tilting during the movement.

A sixth embodiment of the invention is described with reference to FIGS 38 and 39 discussed.

In the sixth embodiment, housing shapes are used 110 . 110 for casting a housing 20 on the insides and, like in 38 is shown, a part of the housing forms extends 110 . 110 as a flat part to the side, making it a lower surface of a holding part 30a ( 30b ) trains. If therefore the two housing forms 110 . 110 are closed, are the holding parts 30a and 30b in contact with the housing shapes 110 . 110 over the lower sides. When the case shapes 110 . 110 are open as in 39 shown, then come the holding parts 30a and 30b out of contact with the housing shapes 110 . 110 even in the area of the lower sides. That means the holding parts 30a and 30b have free space from the surrounding wall surfaces.

When the holding parts 30a and 30b at the holding part forms 120 . 120 are held and move, so they hold, as in 39 is shown, free distance from the surrounding walls and move without contact, so that they on the Ge housing 20 can be moved without any shaving off 140 be generated. Since dust, such as scraping, does not remain in the metal former, the casting accuracy of the subsequently produced holding members becomes 30a and 30b improved.

According to the invention the connector housing and the holding parts can in the preparation of different resins in material or color to the H ^he position of the connector serving for shape and serving for the production of the holding part mold are filled, so that the connector housing and the holding part or the holding parts in Material or color can be formed differently.
