Novel demoulding device for injection mould

Abstract

The invention discloses a novel demoulding device for an injection mould. The novel demoulding device is applied to forming and demoulding of back-off rubber positions on the outer edges of processedproducts. One or more forming parts of the novel demoulding device can be arranged according to requirements, and the forming parts comprise mold cavities, mold core assemblies, and a linkage mechanism for forming / shifting demoulding. The mold core assemblies comprise forming inserts, rotating disks and rear mould mold cores. Each forming insert is a T-shaped circular ring and is arranged on the corresponding rotating disk. The rear mould mold cores penetrate through the rotating disks and the forming inserts, and the rear mould mold cores, the rotating disks and the forming inserts are coaxial. The rotating disks make pendulum-type shifting relative to the axes, forming grooves are formed in the inner circular surface of each forming insert at intervals, and convex teeth are arranged on the inner circular surface of each rotating disk at intervals. When the convex teeth are arranged on the forming grooves in a para-position mode, the normal position, namely the forming position is achieved; and when the convex teeth are arranged on the forming grooves in a dislocation mode, the side position, namely the demoulding position is achieved. According to the novel demoulding device, precision forming can be achieved, demoulding is convenient, the structure is simple, the forming mode of one mould with the multiple products is easy to achieve, and the processing efficiency is advantageously improved.

Description

technical field [0001] The invention belongs to the technical field of injection molds, in particular to a novel demoulding device applied to an injection mold with an undercut glue position on the outer edge of a product. Background technique [0002] In the prior art, for injection molding products with undercut rubber positions, sliders or inclined tops are generally used to realize the buckle release, and the precision of the molded products is not high. A slightly improved demoulding method using movable inserts, the mold The structure is complex and the reliability is poor, which will inevitably cause the instability of product quality. Contents of the invention [0003] In view of the above problems, the present invention focuses on solving the demoulding problem of the undercut glue position on the outer edge of the product. This new demoulding device has the remarkable advantages of high processing precision, simple mold structure and stable product quality. [0...
