Description
Technical field
The utility model relates to a kind of core-pulling mechanism, and more particularly, it relates to a kind of auto parts machinery core-pulling mechanism for injection mold.
Background technology
Injection mold is a kind of instrument being produced plasthetics by injection mo(u)lding, and it is the instrument of some complex-shaped parts of batch production, specifically the material melted that is heated is injected die cavity after cooling curing by high pressure, obtains formed products.
When plastic products sidewall band is porose, groove time, plastic products can not directly be deviate from mould, and it is movable the forming part of forming hole, groove must to be made, and is called moving core, complete active type and to extract out and the mechanism that resets is called core-pulling mechanism.
At present; the multiple hole of usual meeting or groove on the auto parts machinery that some volumes on market are little; this just causes needing multiple core-pulling mechanism to realize operation of loosing core; but general core-pulling mechanism can take some spaces; the volume that multiple core-pulling mechanism just causes whole mould needs to do is very large; not only manufacturing cost space that is high but also that account for is large, is further improved.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of little and auto parts machinery core-pulling mechanism for injection mold of conveniently loosing core of taking up room.
For achieving the above object, the utility model provides following technical scheme: a kind of auto parts machinery core-pulling mechanism for injection mold, comprise punch and die, die cavity is formed between described punch and die, the both sides of described punch are provided with the first inclined plane, described die is provided with the second inclined plane coordinated with the first inclined plane, described first inclined plane is provided with holding tank, pin is provided with in described holding tank, described pin one end passes from punch and is positioned at die cavity, the described pin other end is provided with fixed block, spring is provided with between described fixed block and holding tank diapire, described pin and fixed block removably connect.
The utility model is set to further: the exit of described holding tank is provided with block, and described fixed block is provided with the chute coordinated with block, and the length of described chute equals the length sum that the length of block and pin are positioned at die cavity part.
The utility model is set to further: described pin is provided with Access Division away from die cavity one end, and the face area of described Access Division is greater than pin face area, and described fixed block is provided with the draw-in groove coordinated with Access Division, and described draw-in groove is in T shape.
The utility model is set to further: described fixed block is arranged with interstage sleeve, and described interstage sleeve blocks draw-in groove opening.
Compared with prior art, the utility model has the advantage of: due to the setting of the first inclined plane and the second inclined plane, after punch is separated with die, pin can be ejected under the action of the spring, and then pin shift out from die cavity can the demoulding smoothly, and such core-pulling mechanism takes up room little, when product existing multiple hole or groove, only need arrange in punch that multiple core-pulling mechanism is corresponding with hole or groove just can be realized, and then produced die cost is low and take up room little, the setting of block and chute, make pin when ejecting smoothly, play barrier effect, the situation avoiding pin to eject from holding tank under the action of the spring occurs, pin and fixed block removably connect, like this when pin occurs only need changing pin when damaging, fixed block can continue to use, reduce unnecessary waste, save cost, and it is convenient and swift to change pin.

Detailed description of the invention
Referring to figs. 1 through Fig. 9, the utility model auto parts machinery core-pulling mechanism for injection mold embodiment is described further.
A kind of auto parts machinery core-pulling mechanism for injection mold, comprise punch 1 and die 2, die cavity 3 is formed between described punch 1 and die 2, the both sides of described punch 1 are provided with the first inclined plane 4, described die 2 is provided with the second inclined plane coordinated with the first inclined plane 4, described first inclined plane 4 is provided with holding tank 5, pin 6 is provided with in described holding tank 5, described pin 6 one end passes from punch 1 and is positioned at die cavity 3, described pin 6 other end is provided with fixed block 7, be provided with spring 8 between described fixed block 7 and holding tank 5 diapire, described pin 6 removably connects with fixed block 7.
Due to the setting of the first inclined plane 4 and the second inclined plane, after punch 1 is separated with die 2, pin 6 can be ejected under the effect of spring 8, and then pin 6 shift out from die cavity 3 can the demoulding smoothly, and such core-pulling mechanism takes up room little, when product existing multiple hole or groove, only need arrange in punch 1 that multiple core-pulling mechanism is corresponding with hole or groove just can be realized, and then produced die cost is low and take up room little.
The exit of described holding tank 5 is provided with block 9, and described fixed block 7 is provided with the chute 10 coordinated with block 9, and the length of described chute 10 equals the length sum that the length of block 9 and pin 6 are positioned at die cavity 3 part.
The setting of block 9 and chute 10, makes pin 6 when ejecting smoothly, plays barrier effect, and the situation avoiding pin 6 to eject from holding tank 5 under spring 8 acts on occurs, good stability, facilitates mould normal use next time.
Described pin 6 is provided with Access Division 11 away from die cavity 3 one end, and the face area of described Access Division 11 is greater than pin 6 face area, and described fixed block 7 is provided with the draw-in groove 12 coordinated with Access Division 11, and described draw-in groove 12 is in T shape.
Described fixed block 7 is arranged with interstage sleeve 13, and described interstage sleeve 13 blocks draw-in groove 12 opening.
Face area due to Access Division 11 is greater than pin 6 face area, and draw-in groove 12 is in T shape, pin 6 and fixed block 7 removably connect, only Access Division 11 need be connected to draw-in groove 12 during installation or removal, draw-in groove 12 opening is blocked again by interstage sleeve 13, the situation avoiding pin 6 and Access Division 11 to deviate from draw-in groove 12 occurs, and pin 6 can realize interlock by Access Division 11 and fixed block 7 under spring 8 acts on like this, install or remove convenient and swift, when pin 6 occurs only need changing pin 6 when damaging, fixed block 7 can continue to use, reduce unnecessary waste, save cost.
