Description
Technical field
The present invention relates to injection mold, particularly relate to injection molding mould fixed die oblique top band and touch and wear a side core-pulling mechanism.
Background technology
If working of plastics is all shaped with the structure of barb in cover half side and dynamic model side, upper normally in dynamic model side of prior art, lower ejector retainner plate arranges slide, slide arranges slide block, slide block connects oblique top pin, on passing through when mould die sinking, while lower ejector retainner plate drives oblique top pin to be ejected by working of plastics, oblique top pin extracts barb out to a Slideslip, and cover half side barb is owing to being subject to mould structure restriction, usually can only the bending amplitude of barb and the degree of depth be done little, again by the strong de-barb directly deviating from cover half side, therefore easily there is situations such as breaking in cover half side barb, cause product rejection, in addition due to the needs of product, can not the bending amplitude of cover half side barb and the degree of depth be done little, prior art then cannot be deviate from.
Summary of the invention
The object of the invention is the shortcoming existed to overcome prior art, provide a kind of barb being conducive to deviating from working of plastics dynamic model side and cover half side, structure is simple, and the demoulding is smooth, ensures that the injection molding mould fixed die oblique top band of product quality touches and wears a side core-pulling mechanism.
Injection molding mould fixed die oblique top band of the present invention touches the technical scheme of wearing a side core-pulling mechanism and is: comprise compound plate and lower compound plate, in upper compound plate, centring ring is set, under upper compound plate, backing plate is set, under backing plate, cover half is set, in cover half, gate bush is set, perforation is had in lower compound plate, lower compound plate arranges mould pin, lower compound plate between mould pin is arranged ejector retainner plate and lower ejector retainner plate, injector push rod contacts with lower ejector retainner plate through perforation, on, lower ejector retainner plate arranges straight thimble and slide, slide arranges slide block, slide block connects dynamic model skew back thimble, dynamic model skew back thimble is shaped with convex tendon, mould pin arranges dynamic model, the working of plastics of injection mo(u)lding is had between dynamic model and cover half, working of plastics is shaped with barb and lower riser, lower riser has hole clipping, hole clipping matches with the convex tendon of dynamic model skew back thimble, it is characterized in that: in described cover half, have oblique guide hole, cover half skew back jacking block is set in oblique guide hole, cover half skew back jacking block is shaped with projection, projection matches with the upper barb of working of plastics, mounting-fixing base on oblique guide hole, pilot hole is had in holder, spacing guide rod is set in pilot hole, one of spacing guide rod is shaped with limiting plate, spacing guide rod other end connects cover half skew back jacking block, ejector spring is put at spacing guide rod peripheral hardware, ejector spring one contacts with holder, other end contacts with cover half skew back jacking block, described dynamic model is shaped with to touch and wears position, touch and wear position and contact with cover half skew back jacking block.
The invention discloses a kind of injection molding mould fixed die oblique top band to touch and wear a side core-pulling mechanism, when after working of plastics injection mo(u)lding, lower compound plate band dynamic model pin, dynamic model, upper ejector retainner plate, lower ejector retainner plate, dynamic model skew back thimble, straight thimble and working of plastics together move backward, make mould die sinking, meanwhile, ejector spring promotes cover half skew back jacking block under the effect of restoring force, cover half skew back jacking block synchronously moves backward along with working of plastics, cover half skew back jacking block drives spacing guide rod to move backward, cover half skew back jacking block extracts the upper barb of working of plastics to the inside out while movement backward along the direction that oblique guide hole tilts, when limiting plate contacts with holder, limiting plate is spacing to spacing guide rod, spacing guide rod is held cover half skew back jacking block and is stopped moving backward, and lower compound plate band dynamic model pin, dynamic model, upper ejector retainner plate, lower ejector retainner plate, dynamic model skew back thimble, straight thimble and working of plastics continue to move backward, instantly when ejector retainner plate contacts with injector push rod, injector push rod withstands lower ejector retainner plate, upper ejector retainner plate stops mobile, on, lower ejector retainner plate withstands straight thimble and slide stops mobile, dynamic model skew back thimble on straight thimble and slide withstands working of plastics and stops mobile, thus make working of plastics deviate from dynamic model, withstand while working of plastics deviates from dynamic model at dynamic model skew back thimble, dynamic model moves backward, dynamic model coordinates with dynamic model skew back thimble, dynamic model skew back thimble and slide block are slided the hole clipping of working of plastics to the inside, now working of plastics is just under gravity to falling in collecting box, complete the demoulding, and when matched moulds, touch and wear position and contact with the lower surface of cover half skew back jacking block, wear position and promote cover half skew back jacking block by touching and complete reset.This programme injection molding mould fixed die oblique top band touches wears a side core-pulling mechanism, by arranging cover half skew back jacking block, spacing guide rod, holder and ejector spring in cover half side, make working of plastics be positioned at cover half side barb can loose core smoothly, ensure product quality, and be shaped with to touch on dynamic model and wear position, touch and wear the height of position and the consistency of thickness of working of plastics, wear position and promote cover half skew back jacking block matched moulds by touching and reset, structure is simple, and cover half skew back jacking block resets accurately.
Injection molding mould fixed die oblique top band of the present invention touches wears a side core-pulling mechanism, has through hole in described upper compound plate, and spacing guide rod and limiting plate are through through hole.In matched moulds state, spacing guide rod and limiting plate reach in through hole, can shorten the height of cover half, thus reduce the material manufactured needed for cover half, reduce mould development cost.
