As described above, guide rod 24 has circular-arc recess 244 in the maintained portion 241 of front, the secondary maintained portion 242 of base end side, the rear side of pars intermedia 243.In the inboard of the chamber 51 of sleeve 30, form gathering sill 341 from inserting opening 33 to the depths.
The height (size of space of the 2nd direction D2) of the chamber 51 in the gathering sill 341 forms greatlyyer slightly than the maintained portion 241 of the guide rod 24 of above-mentioned connector 20, the height in the zone outside the gathering sill 341 forms enough forr a short time than maintained portion 241, like this, the maintained portion 241 of guide rod 24 can only be inserted into the inboard of gathering sill 341.
The flat shape of gathering sill 341 forms so-called bell mouth shape, be in the inserting opening 33 side broads of distolateral (rear side of above-mentioned closure DC), along with toward the depth side of chamber 51 being another distolateral (front side of closure DC) of closure DC and attenuating, become predetermined width soon.Like this, the front of the guide rod 24 of connector 20 is subjected to guide properly, and when connecting, connector 20 relative sleeves 30 are guided with becoming predetermined posture.
The bosom part of gathering sill 341 (the sleeve side of closure DC) is swelled gradually, finally becomes and the continuous inclined plane of equal height around the gathering sill 341, forms maintaining part 342 by this inclined plane.In this maintaining part 342, the height of chamber 51 forms roughly the samely with the height of the maintained portion 241 of guide rod 24, and under connection status, the gap size between the leading section of chamber 51 and guide rod 24 is very little.
On the other hand, at the base end part of guide rod 24, the height of secondary maintained portion 242 forms roughly the samely with the height of chamber 51 in the gathering sill 341, under connection status, gap size between the base end part of this part of chamber 51 (secondary maintaining part 343 is with reference to Fig. 8, Figure 10) and guide rod 24 is very little.
Between these maintaining parts 342 and the maintained portion 241 and the gap size between secondary maintaining part 343 and the secondary maintained portion 242 very little, by this state, connector 20 relative sleeves 30 are remained predetermined posture.Such maintenance function be limited to the connection status of connector 20 and sleeve 30 or soon be connected before state, in order to form connection status, connector 20 is being inserted in the way of sleeve 30, by the circular-arc recess 244 of the pars intermedia 243 that is formed at guide rod 24, will keep enough greatly with the size of space of the chamber 51 of sleeve 30, inserting opening 33 etc.
In such guiding mechanism 14, as the guiding of Fig. 8～when connecting as shown in Figure 10.
In Fig. 8, the state that separates with sleeve 30 by connector 20 is arranged it respectively by closure DC, and the front end of guide rod 24 is sent to inserting opening 33.
In Fig. 9, the front end of guide rod 24 that is sent to inserting opening 33 is by 341 pairs of maintained portion 241 channeling conducts of gathering sill, and connector 20 and sleeve 30 are adjusted posture (comprising the posture in the face of closure DC and the 1st direction D1) towards regular connection status.
At this moment, the posture about in the face that comprises closure DC and the 2nd direction D2 is finally led by each maintaining part, so, here can freely tilt.
When attended operation, be inserted into stage in the chamber 51 from the front end of guide rod 24, connector 20 is tilted (with reference to the angle A of Fig. 9) towards the 2nd direction D2, thereby insert operation smoothly and easily.
In the insertion operation of this inclination, the front end of guide rod 24 contacts at contact point P1 with the inner face of the chamber 51 of the face side of sleeve 30, the edge of the rear side of inserting opening 33 contacts at contact point P2 with the circular-arc recess 244 of guide rod 24, thereby can move with being well on.
Along with connector 20 is sent in the sleeve 30, the contact point P1 of face side transfers to the maintenance of maintaining part 342 and maintained portion 241, the contact point P2 of rear side transfers to the maintenance of secondary maintaining part 343 and secondary maintained portion 242, like this, under final connection status, carry out above-mentioned reliable posture and keep.
When extracting, by with the transfer of above-mentioned rightabout contact point, what be well on extracts operation.
In the present embodiment of above explanation, have below shown in effect.
In locking mechanism 13, slide in the inclined plane that tilts towards above-mentioned 3 directions mutually in inclined plane 233,351 as arm side chain bonding part and sleeve side chain bonding part, be pulled away from the occasion that the power of connector 20 with sleeve 30 is applied to closure DC, arm side chain bonding part and sleeve side chain bonding part produce displacement towards the 1st direction D1 and the 2nd direction D2 mutually, can guarantee more firm lock-out state.
On the other hand, when unlocking state, by pushing 1 pair of hammerlock 23 towards the 2nd direction D2 on one side, Yi Bian make it approaching towards the 1st direction D1, thereby move along the inclined plane on the inclined plane 233,351 as arm side chain bonding part and sleeve side chain bonding part, and state can successfully unlock.
In above-mentioned form of implementation, in the inclined plane 351 of sleeve side chain bonding part, operation is then disposed (with reference to Fig. 6) towards the place ahead of closure DC more obliquely with past more inboard, the edge of opening 35, thereby can further improve the anticreep effect.
In addition, be respectively the step of piece 231 of front of hammerlock 23 and operation as the inclined plane 233,351 of arm side chain bonding part and sleeve side chain bonding part, be respectively simple shape, simultaneously, prolong, can easily implement with formation in the past with the edge of opening 35.
In above-mentioned form of implementation, in guiding mechanism 14, as described above the shapes in guide rod 24 and the chamber 51 are constituted predetermined shape, so, can be to the posture channeling conduct when inserting beginning, stage that can be on the way makes processing ease by 2 contacts.In addition, when reaching connection status, the tie point P1 of the face side of sleeve 30 transfers to the maintenance of maintaining part 342 and maintained portion 241, and the contact point P2 of rear side transfers to the maintenance of secondary maintaining part 343 and secondary maintained portion 242, so, can carry out reliable posture and keep.
In addition, the recess 244 of guide rod 24 forms circular-arc necking down, so the guiding that arrives secondary maintaining part 343 sides of connection status also can be carried out smoothly.At the middle body of connector 20 with the pars intermedia of the mutual angle of inclination maximum of sleeve 30, can make size of space maximum, also can guarantee enough intensity by simple shape.
The invention is not restricted to above-mentioned form of implementation, also be contained in the present invention in the distortion of the scope that can realize purpose of the present invention, improvement.
For example, in above-mentioned form of implementation, be provided with the both sides on the inclined plane 351 of the inclined plane 233 of arm side chain bonding part and sleeve side chain bonding part, but the opposing party also can form other shape.For example also the step as the piece 231 of arm side chain bonding part can be become shape for lugs, slide towards incline direction with the inclined plane 351 of sleeve 30.Perhaps, with the edge of the rear side of the closure DC of opening 35 projection of contact usefulness being set, make inclined plane 233 sliding-contacts of hammerlock 23 as the operation of sleeve side chain bonding part.But, by as above-mentioned form of implementation, both sides being formed predetermined inclined plane, thereby can obtain wide contact area, can avoid concentrated load, obtain action smoothly.
In above-mentioned form of implementation, operation then becomes the front side ground tilted configuration of closure DC more with past more inboard, the edge of opening 35, but the inclined plane 351 of sleeve side chain bonding part can obtain the inclination of above-mentioned three directions to get final product, and operation is suitably selected to get final product with the shape at the edge of opening 35.
The angle of inclination on the inclined plane 233 of above-mentioned arm side chain bonding part and the inclined plane 351 of sleeve side chain bonding part etc. can suitably be set corresponding to the bonding operation and the anticreep performance demands condition of reality.
In addition, inclined plane 233,351 is not limited to the plane, also can be curved surface etc., in any of sleeve side and connector side the occasion on inclined plane is set, do not need to consider tight contact at mutual face, so, can set curved surface more freely, also can be according to the gradually changing of curvature or inclination, carry out the setting that the anticreep performance increases etc. gradually corresponding to pulling force.
In above-mentioned form of implementation, the maintained portion 241 of the front of guide rod 24 is formed the height identical with the maintained portion 242 of base end side, but also can form it into littler size.
In Figure 15 and form of implementation shown in Figure 16, the secondary maintained portion 242 that the relative altitude size is big, the height dimension of recess 244 is enough little, and the maintained portion 241 of front is bigger than recess 244, and is littler than secondary maintained portion 242.On the other hand, in sleeve 30, secondary relatively maintaining part 343 is set to high position with maintaining part 342, under connection status, even be thin maintaining part 241, also can positively keep.
In addition, under above-mentioned form of implementation, the height dimension of the maintained portion 241 of the front of guide rod 24 is bigger than pars intermedia 243, but also can form it into same size or littler size.
In Figure 17 and form of implementation shown in Figure 180, the secondary maintained portion 242 big from height dimension attenuates smoothly to recess 244, and the maintained portion 241 from its thinnest position to guide rod 24 front ends is the equal height size.In such occasion, maintaining part 342 is arranged to higher position, can guarantee that operability and the posture under the connection status in inserting the way keeps.
In above-mentioned form of implementation, the recess 244 of pars intermedia 243 is circular-arc, but can be the step-like of essentially rectangular as shown in Figure 19 also, or mild leg-of-mutton recess, and the contour shape of this part is any.But the steering capability of the circular-arc recess 244 that above-mentioned form of implementation is such is good.
In addition, in above-mentioned form of implementation, only be that the rear side at the fastener 10 of the inner face of chamber 51 is provided with the inclined plane as maintaining part 342 that keeps maintained portion 241 when connecting, also can be located at the both sides of the surperficial back side (about among the figure) as shown in Figure 20.Gathering sill 341 also can be located at the surperficial back side both sides etc. of the inner face of chamber 51.
In above-mentioned form of implementation, guide rod 24 is provided with 1 in central authorities, but also can be provided with more than or equal to 2.
In Figure 21 and form of implementation shown in Figure 22, be set up in parallel 2 guide rods 24 at connector 20, maintained portion 241, secondary maintained portion 242 are set respectively.In addition, at sleeve 30, guide rail 344 is located at the face side of chamber 51.This guide rail 344 is at attachment plug 20 during with sleeve 30, is inserted into the gap of 2 24 of guide rods, like this, can obtain to guide the function of the guiding mechanism 14 of connector 20 and sleeve 30.In the occasion of using such guide rail 344, can omit above-mentioned gathering sill 341.
In above-mentioned form of implementation, general fastener 10 has been described, this fastener 10 has arm side chain bonding part (inclined plane 233) at 1 pair hammerlock 23, has guide rod 24 in central authorities, but the invention is not restricted to such formation.For example hammerlock 23 also can be more than or equal to 3, and wherein 2 get final product along the 1st direction D1 alignment arrangements.The lock function that another hammerlock can be used for assisting.Guide rod 24 also can be a plurality of, is not limited to the inboard of 1 pair hammerlock 23, and is also configurable in its outside.
Be not limited to flat pattern as fastener 10, also can be circular cross-section or square etc.
In above-mentioned form of implementation, fastener 10 is used for sheet to be installed, and sleeve 30 is installed on sheet 11 by installing plate 40, but also can the belt installation portion be set at sleeve 30, forms the fastener that interconnects belt.
The fastener that illustrates in above-mentioned form of implementation 10 is owing to have special inclined plane 351,233 etc., so, in the shaping that utilizes general metal pattern to carry out, have difficulties.
By using, can easily form based on injection molding forming metal pattern of the present invention.
Below, illustrate based on the concrete form of implementation of injection molding forming of the present invention with metal pattern.
In Figure 23～Figure 25, but the injection molding forming of this form of implementation has fixed die 60 and dynamic model 70 with metal pattern 50, and portion forms the chamber 51 of shaping usefulness within it.
Injection molding forming is installed on original injection molding machine (omitting diagram) with metal pattern 50 and uses.Fixed die 60 is installed on the fixation side of injection molding machine, but dynamic model 70 is installed on the movable side of injection molding machine, by the clamping of injection molding machine matched moulds mutually.Under matched moulds state (with reference to Figure 23), from the injection device of injection molding machine molten resin is expelled in the chamber 51, solidify along with cooling, obtain drip molding (connector 20 described later).
In order to take out drip molding, at fixed die 60 push-off pin 61 is set, by not shown driving mechanism this push-off pin 61 is entered in the chamber 51, can eject drip molding (with reference to Figure 24 and Figure 25).But the approach axis of this push-off pin 61 is set at the matched moulds die sinking direction with fixed die 60 and dynamic model 70.
In this form of implementation, injection molding forming is a connector 20 as the positive side of the fastener of the connection that is used for belt etc. with the drip molding of metal pattern 50.
Here, hammerlock 23 is in order to carry out and the engaging of sleeve, and has alone arrow shaped 25 at fore-end.This arrow shaped 25 toward outside protuberance, simultaneously, forms step at the mid portion of hammerlock 23 from the front end of hammerlock 23 towards base portion, and the outside of the step surface of this part is at the position by base portion, inboard front end near hammerlock 23, thus form so-called arrowhead form.
The direction in length and breadth of the relative connector 20 in the edge in the outside of the above-mentioned step surface of arrow shaped 25 is formed obliquely.That is, in Figure 26 or Figure 27, the horizontal of drawing is the horizontal of connector 20, and the direction of quadrature is the vertical of connector 20 in the drawing.The edge tilt in the outside of arrow shaped 25 makes among the figure outside become the inboard of drawing, inboard among the figure (near a side of guide rod 24, a relative side) mutually becomes the front face side of drawing.
More than such arrow shaped 25 in the shaping of connector 20, become down recess, the recess that should fall becomes the direction that the vertical and horizontal with connector 20 all intersect.That is be the preceding extreme direction of the hammerlock 23 of connector 20, as falling the depth direction of arrow shaped 25 of recess.
For the above-mentioned connector 20 that is shaped, chamber 51 forms along the interior shape of the profile of connector 20.But fixed die 60 and dynamic model 70 be at horizontal (page of Figure 26, Figure 27) setting die joint of connector 20, and longitudinally (with the direction of drawing quadrature) carries out the matched moulds die sinking (with reference to Figure 23～Figure 25).
In such metal pattern 50, when existing, can not extract connector 20 simply as drip molding as above-mentioned arrow shaped 25 of falling recess.Therefore, the injection molding forming of this form of implementation, has the slide cores 80 that can be set in the chamber 51 with advancing and retreat and makes this slide cores 80 produce the displacement mechanism 90 of displacement towards the direction of falling the concave depth in order to form down recess with metal pattern 50.
Its front end of the state that slide cores 80 is in the end moved back (with reference to Figure 23) also is projected in the chamber 51.This fore-end is in the space that is adjacent to arrow shaped 25 in the outside of the hammerlock 23 of connector 20, does not interfere with the connector 20 as drip molding.
Side surface at the fore-end of slide cores 80 forms forming face 82.The direction that this forming face 82 is provided be connector 20 hammerlock 23 front end towards a side, the promptly above-mentioned depth direction that falls recess (arrow shaped 25).
Form the contour shape (direction of falling the recess depths concavo-convex) of the shaping usefulness corresponding with the part of falling the recess (arrow shaped 25) of above-mentioned connector 20 in this forming face 82, under the matched moulds state, become unique part that is exposed to chamber 51 inner faces in slide cores 80, become and the continuous forming face of other inner face that is disposed at chamber 51 on every side, as a whole, form the contour surface of connector 20.
For this reason, displacement mechanism 90 have slide cores of being formed at 80 mid portion inclined plane 91,93 and be formed at the contact site 92,94 of each peristome of guide pin bushing 81.Here, inclined plane 91 forms the cam face with contact site 92 sliding-contacts, and inclined plane 93 forms the cam face with contact site 94 sliding-contacts.
Fore-end in slide cores 80, the size of the above-mentioned direction of falling the recess depths forms roughly consistently with the equidirectional size of guide pin bushing 81, under the state of the fore-end of slide cores 80 in being in guide pin bushing 81, keep slide cores 80 reliably at contact site 92 peripheries, can not produce displacement (state of Figure 23) in the same direction.
When slide cores 80 enters chamber 51,91 move along the inclined plane with the contact portion of contact site 92, slide cores 80 becomes allows by the displacement on inclined plane 91 towards the state (state of Figure 24) that moves with the direction of falling recess depths opposition side.
On the other hand, the size of the part of base end side forms greatly towards the inclined plane 93 of the direction ratio of falling recess depths slide cores 80.For this reason, in the time of in slide cores 80 enters chamber 51, as coming inclined plane 93 with contacting of contact site 94, then slide cores 80 produces displacement (state of Figure 25) by this inclined plane 93 towards an opposite side with the direction of falling the recess depths.
Make forming face 82 from as falling such displacement that the arrow shaped 25 of recess keeps out of the way like this, as described above.
In this such form of implementation, carry out following action according to injection molding method of the present invention.
At first, but closed fixed die 60 and dynamic model 70 make that push-off pin 61 and slide cores are after 80s moves back, and prepare predetermined shaping usefulness contour shape (state of Figure 23) chamber 51 in.
Under this state, molten resin is expelled in the chamber 51, cool off in inside by this state, being cured as drip molding is connector 20.At this moment, form as falling the arrow shaped 25 of recess by the forming face 82 of slide cores 80 at connector 20.
Then, but open fixed die 60 and dynamic model 70, push-off pin 61 and slide cores 80 are entered, take out connector 20 from fixed die 60.
At this moment, as falling the state of forming face 82 for carrying out concavo-convex cooperation towards the direction of falling the recess depths of arrow shaped 25 and slide cores 80 of recess, slide cores 80 can not be separated (state of Figure 24) under this state with connector 20.
Yet, when push-off pin 61 and slide cores 80 further enter, slide cores 80 produces displacement by displacement mechanism 90 towards the direction of falling recess depths opposition side, removes the concavo-convex mated condition of above-mentioned arrow shaped 25 and forming face 82, and connector 20 becomes the state (state of Figure 25) that freely takes out.
According to this such form of implementation, has following such effect.
Promptly, side in slide cores 80, be provided with and the corresponding forming face 82 of concaveconvex shape of recess, by displacement mechanism 90 make slide cores 80 towards and the direction of falling recess depths opposition side produce displacement, so, can be shaped as the arrow shaped 25 of recess by forming face 82, simultaneously, under die opening state, can partly make a concession from falling recess, can not hinder taking-up as the connector 20 of drip molding.
In addition, slide cores 80 and displacement mechanism 90 fore-end to slide cores 80 under the matched moulds state moves restriction, so, can positively accept the injection pressure of molten resin, can guarantee correct shaping.
In addition, the free degree according to above-mentioned directionality, as the connector 20 of this form of implementation, exist and falling the occasion (having the plug bodies 21 relative) of the relative part of recess with arrow shaped 25 at drip molding, also can guarantee the displacement that displacement mechanism produces, can freely dispose slide cores 80 and its advance and retreat direction.
But slide cores 80 is in the matched moulds direction advance and retreat of fixed die 60 and dynamic model 70, so, can carry out and the synchronization action that is arranged at the push-off pin 61 of equidirectional usually, simultaneously, can easily prolong with driving mechanism etc.
The invention is not restricted to above-mentioned form of implementation, can realize that the distortion, improvement etc. in the scope of purpose of the present invention also are contained in the present invention.
For example, in above-mentioned form of implementation, with push-off pin 61, slide cores 80, and displacement mechanism 90 be set to fixed die 60 sides respectively, but the invention is not restricted to this.
For example, but push-off pin 61, slide cores 80, displacement mechanism 90 also can be set to dynamic model 70.But the setting of driving mechanism is preferably fixation side.
The advance and retreat of slide cores 80 drive can with the clamping dual-purpose, driving mechanism alone also can be set, for example Zhuan Yong motor or solenoid, hydraulic cylinder etc.
Push-off pin 61 and slide cores 80 are not necessarily leaveed no choice but in the equidirectional advance and retreat, and slide cores 80 configurations best and recess correspondingly are configured to suitable position.In this occasion, the shared change of driving mechanism is difficult, even but mutual direction or the position difference is set also can use suitable linkage etc. shared.
As displacement mechanism 90, be not limited to use the cam face on the inclined plane 91,93 of the contact site 92,94 of above-mentioned guide pin bushing 81 and slide cores 80.For example also available other locking mechanism etc. carries out the position restriction of matched moulds state separately, as long as have the contact site 94 of the displacement action that is used to carry out essence and the cam face on inclined plane 93 at least.
In addition, displacement mechanism 90 is not limited to be formed at the cam face of slide cores 80, also can for example make slide cores 80 produce displacement etc. to each guide pin bushing 81 by independent driving mechanisms.
In this form of implementation, as drip molding the connector 20 that fastener is used has been described, but the present invention can be used for having down the diversified shaping of recess.
