Externalinclined core pulling device of injection mold

Abstract

The inventiondiscloses an externalinclined core pulling device of an injection mold. The externalinclined core pulling device comprises an inclined core pulling rod (1),an inclinedsliding foot (2), a horizontal sliding block (3), a longitudinal sliding block (4) and a sliding seat (5). According to the device, the inclined core pulling rod is connected ontotheinclined sliding foot; the inclined sliding foot is fastened onthe left inclined surface of the horizontal sliding block in a sliding manner; the horizontal sliding block is fastened on and connected with the sliding seat in a slidingmanner; the lower part of the longitudinal sliding block is fastenedon the right inclined surface of the horizontal sliding block in asliding manner; the upper part of the longitudinal sliding block is fixedly connected with theouter wall of a fixed mold loading plate; thesliding seat is fixedly connected with a movable mold loading plate; theinclined core pulling rod slides in an inclined manner and penetrates through themovable mold loading plate and a core; an inclined hole core is raised out of the upper surface of the core. During work, a mold is used for mold disassembling, the longitudinal sliding block pulls the horizontal sliding block to move rightward; the horizontal sliding block pulls theinclined sliding foot andtheinclined core pulling rod to move rightwards and downwardsso as to pull the inclined hole core out of a product in an inclined manner. According to the technical scheme, for the injection moldto be subjected to inclined core pulling, the aims that the shape of the mold is reducedand the comprehensive cost is reduced can be achieved.

Description

technical field [0001] The invention relates to a core-pulling and demoulding device for an injection mold, in particular to an external injection mold device for obliquely extracting a core block embedded in an undercut structure of a product without occupying the inner space of the mold. Inclined core pulling device. Background technique [0002] Undercut refers to the inclined hole, flange, hook or rib structure in which the core-pulling and demoulding direction of the injection molded product intersects with the opening and closing direction of the mold; the prior art injection mold adopts an inclined top core-pulling mechanism driven by the top plate, or The oblique core-pulling mechanism driven by the horizontal slider performs oblique core-pulling and demoulding on the undercut structure of the product; since these mechanisms are all located inside the mold, they all need to occupy the internal space of the mold, which increases the shape of the mold , just need to u...
