Description

Mold with ejecting push plate elder generation drawing machine structure
Technical field
The utility model is related to a kind of injection mold, especially a kind of mold with ejecting push plate elder generation drawing machine structure.
Background technology
Injection mold is a kind of tool producing plasthetics, is also to confer to plasthetics complete structure and accurate dimension Tool, the plastics melted that are heated are injected by injection molding machine high pressure in the cavity of mold, after cooling and solidifying, you can obtain formed products. When carrying out the production of product using injection mold, in die industry, the special product of certain shapes is difficult to be set on mold Top set needle to carry out the ejection of product, while rear mold enter son it is long if be also unfavorable for ejection action, if ejection causes by force Product gross distortion, the damage of product, even die ejector pin be broken the problems such as.Therefore need one kind that can solve above-mentioned ask now The method or apparatus of topic.
Invention content
The utility model is to propose that one kind is simple in structure, design is skilful to solve the above-mentioned deficiency present in the prior art It is wonderful, it is rationally distributed, it can realize and demould stage by stage, what guarantee special shape workpiece can be demoulded smoothly there is ejecting push plate first to pull out The mold of mechanism.
The technical solution of the utility model is:A kind of mold with ejecting push plate elder generation drawing machine structure, including front template 1 With rear pattern plate 2, mould mode 3 before being provided on front template 1 is provided with rear mold mode 4, and preceding mould mode 3 and rear mold on rear pattern plate 2 Mode 4 is mutually matched, it is characterised in that:The rear pattern plate 2 is made of rear mold push plate 5 and rear mold fixed plate 6, the rear mold mode 4 be arranged in rear mold push plate 5, activity, which is worn, in rear mold push plate 5 is connected to release link 7, and the both ends of release link 7 respectively with positioning spiral shell Silk 8 is connected with top nail-plate 9, push plate counterbore 10 is offered in the rear mold push plate 5, the end of the set screw 8 is located at push plate In counterbore 10, it is further opened with push plate deep gouge 11 in rear mold push plate 5, is provided in the push plate deep gouge 11 and is socketed in release link 7 On push plate spring 12, rear mold fixed plate 6 and top nail-plate 9 between there are gaps 13, and rear mold fixed plate 6 with top nail-plate 9 Between release link 7 on be also socketed with resetting spring 14, be also fixedly connected with and first pulled out into sub- mold insert 15 in rear mold fixed plate 6, The end for first pulling out sub- mold insert 15 is located in the cavity formed by preceding mould mode 3 and rear mold mode 4, and first pulls out into sub- edge Part 15 can be moved relative to rear mold push plate 5, be connected by nylon mode locker 16 between the front template 1 and rear mold push plate 5.
The utility model compared with the existing technology, has the following advantages that:
The mold with ejecting push plate elder generation drawing machine structure of this kind of structure type, simple in sturcture, ingenious in design, layout is closed Reason, it the problems of during demoulding, designs a kind of mold knot that stage demoulding can be achieved for certain workpiece Structure, it, which is allowed first between sub- mold insert and workpiece, generates a bit of relative displacement, then after complete die sinking, utilizes pushing away for movement Plate driving workpiece is completely disengaged with sub- mold insert is entered, and this structure avoids using longer thimble or mandril, so as to avoid using Existing various hidden danger when longer thimble.And its manufacture craft is simple, and manufacturing cost is cheap, it can be said that it has A variety of advantages, particularly suitable for promoting and applying in the art, market prospects are very wide.
Figure of description
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific implementation mode
Below in conjunction with description of the drawings specific embodiment of the present utility model.As shown in Figure 1:One kind having ejecting push plate The mold of first drawing machine structure, including front template 1 and rear pattern plate 2, mould mode 3 before being provided on front template 1 are provided on rear pattern plate 2 Rear mold mode 4, and preceding mould mode 3 and rear mold mode 4 are mutually matched, the two can be collectively formed cavity, above-mentioned rear pattern plate 2 by Rear mold push plate 5 and rear mold fixed plate 6 form, and rear mold mode 4 is just arranged in rear mold push plate 5, in rear mold push plate 5 activity wear It is connected to release link 7, and the both ends of release link 7 are connected with set screw 8 and top nail-plate 9 respectively, are offered in the rear mold push plate 5 The end of push plate counterbore 10, the set screw 8 is located in push plate counterbore 10, and push plate deep gouge is further opened in rear mold push plate 5 11, be provided with the push plate spring 12 being socketed in release link 7 in the push plate deep gouge 11, rear mold fixed plate 6 and top nail-plate 9 it Between there are gaps 13, and rear mold fixed plate 6 and top nail-plate 9 between release link 7 on be also socketed with resetting spring 14, in rear mold It is also fixedly connected with and is first pulled out into sub- mold insert 15 in fixed plate 6, it is described first to pull out the end into sub- mold insert 15 positioned at by preceding 3 He of mould mode It in the cavity that rear mold mode 4 is formed, and first pulls out and can be moved relative to rear mold push plate 5 into sub- mold insert 15, and 1 He of front template It is connected by nylon mode locker 16 between rear mold push plate 5.
The course of work of the mold with ejecting push plate elder generation drawing machine structure of the utility model embodiment is as follows:In molding machine Under effect, front template 1 and rear pattern plate 2(It is made of rear mold push plate 5 and rear mold fixed plate 6)It is bonded to each other, preceding mould mode 3 and rear mold Cavity is formed after 4 split of mode, the material of molten state is filled into cavity, forms product after cooling;
When needing die sinking, molding machine sheds external force, under the action of push plate spring 12, is connected by nylon mode locker 16 Front template 1 and rear mold push plate 5 are moved away from the direction of rear mold fixed plate 6 jointly, when the end of set screw 6 and push plate are heavy When the bottom face contact in hole 10, above-mentioned movement reaches capacity position, during this, due to first pulling out after sub- mold insert 15 is fixed on In mould fixed plate 6, therefore first pulls out sub- mold insert 15 and can be realized " first with the relative displacement of the workpiece generation certain distance in cavity Pull out " operation;
Then molding machine drive front template 1 continue away from rear mold fixed plate 6 direction move, at this time front template 1 with Power between rear mold push plate 5 is more than binding force caused by nylon mode locker 16, and front template 1 is detached with rear mold push plate 5, and cavity is opened Workpiece is fully exposed by Qi Hou(But workpiece, which still supports, formerly to be pulled out on sub- mold insert 15);
Finally, driving top nail-plate 9 is moved towards the direction of workpiece(Gap 13 becomes smaller), the top drive drive of release link 7 of nail-plate 9 Rear mold push plate 5 acts, and is relatively-stationary due to first pulling out into sub- mold insert 15, this action of rear mold push plate 5 can drive work Part falls off from the end for first pulling out sub- mold insert 15, realizes the demoulding of workpiece, hereafter, under the action of resetting spring 14, top nail Plate 9 can return to initial position again, wait for next task.
