Description

Injection mold lever secondary ejecting mechanism
Technical field
This utility model is related to injection mold, more particularly to injection mold lever secondary ejecting mechanism.
Background technology
After injection mold is to working of plastics injection mo(u)lding, if being formed with concave station on working of plastics, and working of plastics side wall is formed with arc bag Side, working of plastics is excessive to the package power of core, if directly adopting thimble to eject, thimble lifting surface area is little, then be likely to result in and mould Materials and parts by bursting, the yield rate affecting product it is therefore desirable to working of plastics be ejected using an area larger big jacking block, then by Thimble pass through big jacking block, working of plastics eject from jacking block, prior art be when ejector retainner plate drive big jacking block eject upwards same When, drive thimble to push up upwards together by oil cylinder, after working of plastics is ejected by big jacking block, big jacking block stops moving, now oil cylinder Continue to drive thimble that working of plastics is ejected from big jacking block, this structure adopts oil cylinder to drive thimble, and the manufacturing cost of oil cylinder is high, carries The high development cost of mould, increases the volume of mould, and need big jacking block stop mobile after, oil cylinder could drive thimble Top working of plastics, reduces production efficiency.
Content of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art to exist, and provides a kind of structure simple, reduces mould Tool development cost, the injection mold lever secondary ejecting mechanism of improve production efficiency.
The technical scheme of this utility model injection mold lever secondary ejecting mechanism is:Including lower compound plate, on lower compound plate Setting support block and ejector retainner plate, support block arranges core, and core outer wall arranges oil cylinder, and the piston rod of oil cylinder is connected with ejector retainner plate Connect, core arranges core insert, in core insert, jacking block is set, core insert has the working of plastics of injection mo(u)lding, working of plastics Top is formed with concave station, and the side wall of working of plastics is formed with arc bound edge, arranges straight push rod on ejector retainner plate, and straight push rod is connected with jacking block Connect it is characterised in that:Setting secondary push plate and lever seat on described ejector retainner plate, arrange cushion block, cushion block is through tight under secondary push plate Firmware is fixed with secondary push plate phase, and secondary push plate arranges secondary push rod, and secondary push rod is contacted through jacking block with working of plastics, Arc lever is set in lever seat, and arc lever is through rotating shaft and lever seat rotatable engagement, one of arc lever and secondary push plate Lower end contact, push rod is set under core, push rod contacted with the other end of arc lever.
The utility model discloses a kind of injection mold lever secondary ejecting mechanism, after working of plastics injection mo(u)lding, mould Tool die sinking, the piston rod of oil cylinder drives ejector retainner plate to move up, ejector retainner plate drive straight push rod, secondary push plate and lever seat simultaneously to Upper movement, straight push rod promotes jacking block, and secondary push plate drives secondary push rod, jacking block and secondary push rod synchronously to eject working of plastics upwards Core, when lever seat is moved upward to push rod position under core, one of arc lever is contacted with push rod, due to pushing away Bar is to maintain static, and ejector retainner plate, straight push rod, secondary push plate, lever seat, arc lever continue to move up, therefore sissy bar When one, bar is contacted with push rod, arc lever other end then rotates up around rotating shaft, and the other end of arc lever promotes two Secondary push pedal accelerates to move up, and secondary push plate drives secondary push rod to accelerate to move up, and secondary push rod passes through jacking block by working of plastics Accelerate to eject upwards, make working of plastics depart from jacking block, complete the demoulding.This programme injection mold lever secondary ejecting mechanism, makes mould During die sinking ejection, working of plastics is ejected core to tool by first jacking block and the synchronization of secondary push rod, recycles arc lever and pushes away The cooperation of bar, makes secondary push rod accelerate to move up working of plastics ejects jacking block upwards, structure is simple, reduces mould development and become This, Double-ejection action is not take up the time of once ejection action(I.e. the action of ejection for the first time need not stop, Double-ejection Working of plastics can be ejected), improve production efficiency.
This utility model injection mold lever secondary ejecting mechanism, described secondary push plate arranges bumper post, buffering Buffer spring is set under post.There are bumper post and buffer spring, make secondary push plate drive secondary push rod to accelerate to eject upwards plastics Buffered after part, it is to avoid collide it is ensured that its service life with die cavity lower end.
