Lateral parting core-pulling device with oscillating hook for plastic molds

Abstract

The invention belongs to the technical field of plastic molds, and particularly relates to a lateral parting core-pulling device with an oscillating hook for plastic molds. The lateral parting core-pulling device with an oscillating hook for plastic molds comprises a movable mold seat plate, bolsters, a supporting plate and a movable mold plate which are successively fixedly connected, the movablemold seat plate and the bolsters are connected through set screws; the two bolsters are positioned on the upper surface of the movable mold seat plate; an oscillating hook structure is arranged between the two bolsters; a square through hole is formed in the movable mold plate; a movable mold core is placed in the square through hole; a plastic part is arranged on the movable mold core; the oscillating hook of the oscillating hook structure clamps the movable mold core; a push rod fixing plate is connected to the supporting plate through a pushing-out mechanism resetting rod; and the supporting plate is fixedly connected with the movable mold core through movable mold core setting screws. Parts such as a lifter base and a sliding guide plate in a lifting lateral core-pulling mechanism anda pressing block, a wedge block, an oblique guiding block and a wear-resistant plate in an oblique guiding block lateral parting core-pulling mechanism can be omitted. The lateral parting core-pulling device with the oscillating hook for the plastic molds has the advantages of simple structure, capability of greatly reducing costs and the like.

Description

technical field [0001] The invention belongs to the technical field of plastic moulds, and in particular relates to a side-parting core-pulling device for a swing hook of a plastic mould. Background technique [0002] When the plastic part has a side convex or side concave that is inconsistent with the mold opening direction, it is difficult to release the plastic part from the mold cavity after molding, and the mold parts formed there must be made into parts that can move sideways. The mechanism that drives the movement of the lateral parts is called the lateral split core-pulling mechanism. The side core pulling mechanism is more complicated, which will greatly increase the cost of the mold. [0003] At present, the common lateral parting core-pulling mechanisms include inclined guide column lateral parting and core-pulling mechanism, curved pin lateral parting and core-pulling mechanism, inclined slider lateral parting and core-pulling mechanism, inclined guide groove L...

AI Technical Summary

Problems solved by technology

[0006] The mold structure of the inclined guide column and the inclined top lateral parting core-pulling mechanism are relatively complex, with more parts, higher mold cost, increased production cost, and increased burden on the enterprise
