Description
Technical field
The utility model relates to mould, is specifically related to a kind of injection mold.
Background technology
Injection mold is a kind of instrument producing plasthetics, is also the instrument giving plasthetics complete structure and accurate dimension.In use, the material that heat is melted is injected die cavity by cast gate, after cooling curing, obtains formed products.Conveniently formed products exits die cavity, generally in push pedal, vertically installs circular or square thimble, by thimble, formed products is ejected in die cavity.This to eject formed products feeding mode too simple, once formed products volume is comparatively large, need establish multiple thimble, technique is loaded down with trivial details, and in addition, formed products is in ejection process, and the stuck imagination easily appears in part thimble, so that formed products can discontinuity, fragile.
Utility model content
In order to solve the problem, the utility model provides a kind of injection mold of easy taking-up formed products, and concrete technical scheme is as follows:
A kind of injection mold, comprise upper bolster, die shoe, patrix, counterdie, push pedal and guide pillar, upper bolster center is provided with cast gate, patrix is fixedly mounted below upper bolster, counterdie is provided with below patrix, upper die and lower die surrounding is provided with guide pillar, die joint is formed between upper die and lower die, the push pedal that can move up and down is provided with above die shoe, described push pedal is provided with oblique top pin, counterdie is provided with the centre hole matched with oblique top pin, narrow wide under centre hole, oblique top pin comprises thimble seat, left thimble and right thimble, thimble seat is fixedly connected with push pedal, left thimble and right thimble are slidably installed thimble seat, left thimble and right thimble are arranged on counterdie inside through thimble hole deviation.
Preferably, described oblique top pin is provided with two groups.
Preferably, above described thimble seat, be provided with T-slot, below described left thimble and right thimble, be provided with the T-shaped step matched with T-slot.
Preferably, described push pedal is provided with the push rod driving patrix movement, the sheathed spring of push rod outer circumferential side.
Preferably, the top of described left thimble and right thimble is provided with step mutually to the inside.
The beneficial effects of the utility model: formed products after cooling forming, push pedal moves in die cavity, thus driving oblique top pin moves, oblique top pin coordinates with lower narrow wide centre hole, left thimble and right thimble slowly strut to both sides in upper process of moving, thus hold out against the both sides of formed products, and formed products is ejected, formed products is facilitated to pick and place, ejection process stress balance, not easily damaged formed products, left thimble and right thimble are slidably installed thimble seat, there will not be stuck phenomenon, can flexible modulation.
Accompanying drawing explanation
Fig. 1 is the structure chart of mould of the present utility model;
Fig. 2 is the sectional view of the B-B in Fig. 1;
Fig. 3 is the stereogram of oblique top pin of the present utility model;
Fig. 4 is the exploded view of oblique top pin of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As depicted in figs. 1 and 2, a kind of injection mold, comprise upper bolster 1, die shoe 2, patrix 3, counterdie 4, push pedal 5 and guide pillar (not shown), upper bolster 1 center is provided with cast gate 11, the material that heat is melted enters mold cavity by cast gate 11, the upper mold base 9 of fixed installation below upper bolster 1, upper mold base 9 inside fixed installation patrix 3, lower mold base 10 is provided with below upper mold base 9, lower mold base 10 inside fixed installation counterdie 4, upper mold base 9 and lower mold base 10 surrounding are provided with guide pillar, die joint is formed between patrix 3 and counterdie 4, the push pedal 5 that can move up and down is provided with above die shoe 2, push pedal 5 is provided with the push rod 8 driving upper mold base 9 movement, push rod 8 heads on mold base 9 through lower mold base 10, the sheathed spring of push rod 8 outer circumferential side, Spring driving push pedal 5 resets.
Patrix 3 is arranged on that mold base 9 is inner, and counterdie 4 is arranged on the inside of lower mold base 10, is the maintenance conveniently after burn failure.Patrix 3 can be made of one with upper mold base 9, and counterdie 4 can be made of one with lower mold base 10, does not affect the normal use of the utility model mould.
Described push pedal 5 is provided with oblique top pin 7, and counterdie 4 is provided with the centre hole matched with oblique top pin 7, narrow wide under centre hole, and oblique top pin 7, through lower mold base 10, is movably arranged on centre hole.Oblique top pin 7 is provided with two groups, often organize oblique top pin 7 and comprise thimble seat 71, left thimble 72 and right thimble 73, thimble seat 71 is fixedly connected with push pedal 5, thimble seat 71 top is placed in lower mold base 10, left thimble 72 and right thimble 73 are slidably installed thimble seat 71, and it is inner that left thimble 72 and right thimble 73 are arranged on counterdie 4 through thimble hole deviation.
As shown in Figure 3 and Figure 4, be provided with T-slot above described thimble seat 71, be provided with the T-shaped step matched with T-slot below described left thimble 72 and right thimble 73, left thimble 72 and right thimble 73 are slidably mounted in the T-slot of thimble seat 71.The top of left thimble 72 and right thimble 73 is provided with step mutually to the inside, and step is beneficial to and holds out against products formed.When thimble seat 71 is along with when push pedal 5 moves, left thimble 72 and right thimble 73 in centre hole on move, because of narrow wide under centre hole, left thimble 72 and right thimble 73 top strut, and movement is inwardly shunk in bottom, left thimble 72 and right thimble 73 top strut and eject formed products gradually.
Injection mold of the present utility model is when getting formed products, as shown in Figure 2, push pedal 5 moves, drive on push rod 8 and move, push rod 8 ejects upper mold base 9 through lower mold base 10, thus patrix 3 is separated with counterdie 4, simultaneously, push pedal 5 drives on oblique top pin 7 and moves, oblique top pin 7 moves on lower mold base 10 is in the centre hole of counterdie 4, because oblique top pin 7 times is narrow wide, left thimble 72 and right thimble 73 move past in journey upper, top struts gradually, formed products is ejected gradually, formed products both sides stress balance, not easily damaged, left thimble 72 and right thimble 73 activity are flexibly, not easily stuck, relative to general circle or square thimble, rational in infrastructure, just formed products can be ejected without the need to arranging multiple thimble.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
