Description

The universal core-pulling mechanism of plastic chair backup plate mould
Technical field
The utility model relates to a kind of universal core-pulling mechanism in stud location hole for processing plastic chair backup plate mould, belongs to injection mold field.
Background technology
At present, the kind of chair has a lot, wherein have and a kind of mould in conjunction with chair for wood, concrete structure example as seat support and chair backup plate be that plastics are made, chair back is wooden column, curved fan-shaped the standing on seat support of many root posts, chair backup plate interts on the top of column, in chair backup plate, there is locating hole, due to curved fan-shaped the arranging of column, therefore also each portion is identical for the angle that each root post tilts, the angle of inclination of relative locating hole is not identical yet, conventional method is by the moulding of chair backup plate integral molded plastic, then on chair backup plate, get out singly the locating hole of each root post, labour intensity is high, efficiency is low, cost is large, need to develop a kind of chair backup plate injection mold with locating hole.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, provides a kind of and adopts universal oblique cunning to loose core, and makes locating hole and chair backup plate single injection-molded, saves cost, the universal core-pulling mechanism of the plastic chair backup plate mould of enhancing productivity.
The technical scheme of the universal core-pulling mechanism of the utility model plastic chair backup plate mould is: comprise upper mould plate and lower bolster, under cope match-plate pattern, solid plate is installed, mould pin is installed on lower bolster, on mould pin, dynamic mould fixing plate is installed, moving platen is installed on dynamic mould fixing plate, gap between moving platen and solid plate forms die cavity, in die cavity, there is the chair backup plate of injection mo(u)lding, in chair backup plate, be shaped with locating hole, upper plate and lower roof plate are set between mould pin, on upper plate, connect push rod, push rod contacts with chair backup plate through moving platen, it is characterized in that, in described dynamic mould fixing plate, universal oblique slide is installed, in universal oblique slide, be shaped with chute, universal oblique sliding core_pulling pole is set in chute, universal oblique sliding core_pulling pole matches with locating hole through moving platen.
The universal core-pulling mechanism of plastic chair backup plate mould of the present utility model, main feature is that universal oblique slide is installed in dynamic mould fixing plate, in universal oblique slide, be shaped with chute, universal oblique sliding core_pulling pole is set in chute, when the demoulding, by the die sinking of die sinking oil cylinder driven mold dynamic model part, moving platen and dynamic mould fixing plate move downwards, drive universal core_pulling pole to loose core, simultaneously, slide in universal core_pulling pole angle of inclination along locating hole in chute, universal core_pulling pole is extracted out smoothly from locating hole, again by upper, lower roof plate drives push rod by outside chair backup plate ejection die, complete the demoulding.This programme has overcome the defect of traditional moulds, adopts universal oblique cunning to loose core, and makes locating hole and chair backup plate single injection-molded, enhances productivity, and reduces production costs.
The universal core-pulling mechanism of plastic chair backup plate mould of the present utility model, is shaped with holddown groove in described dynamic mould fixing plate, and universal oblique slide is installed in holddown groove, and is fixed convenient fixing, firm by press strip and screw.
