Description

Technical Field

[0001] The utility model relates to the technical field of demoulding, in particular to a plastic part demoulding mechanism which is convenient for arranging and discharging materials. Background Art

[0002] When casting plastic parts with complex shapes, templates with multiple layers of mold cores or grooves are usually combined. The grooves and mold cores between the multiple layers of templates together form a molding cavity for the plastic parts; during demoulding, a demoulding mechanism drives the multiple layers of templates to move in sequence for demoulding.

[0003] For example, Chinese Patent CN220331854U discloses a demoulding mechanism. This mechanism drives a moving block to move through a motor and a screw rod, thereby driving clamping plates to clamp both sides of the upper mold. An anti-slip pad can enhance the friction force to prevent dropping.

[0004] However, for some plastic parts with grooves on all four sides, it is difficult to demould multiple rows or columns of plastic parts through one-way movement without damaging the plastic parts during demoulding.

A plurality of positioning rods 11 are symmetrically and fixedly installed on the moving frame 1. The upper plate 2 is fixedly installed on the lower side of the moving frame 1. The positioning rods 11 are sequentially and limit-slidingly connected to the upper plate 2, the top plate 3, and the bottom plate 5 from top to bottom.
