Anti-rubber-overflow and keep-space structure of mold

Abstract

The invention belongs to the technical field of high-end equipment manufacturing, and particularly relates to an anti-rubber-overflow and keep-space structure of a mold. The structure is characterizedby comprising an upper mold base and a lower mold base arranged at the bottom of the upper mold base, a mold core is arranged in a mold cavity between the upper mold base and the lower mold base, andsupporting legs are evenly arranged at the top and the bottom of the mold core; and embedding blocks are symmetrically arranged on the left side and the right side of the mold core, clamping groovesmatched with the embedding blocks are connected to the corresponding positions of the left side wall and the right side wall of an inner cavity of the upper mold base, and clamping plates are connected to the edges of the bottom of the upper mold base. According to the anti-rubber-overflow and keep-space structure of the mold, the supporting legs are arranged, so that a large amount of heat transfer generated by direct contact between the mold core and the mold bases is reduced, the service life of the mold bases is prolonged, and furthermore, the situation that the quality of a formed productis reduced due to the heating deformation of the mold bases is reduced; the good supporting effect on the mold core is achieved through the actions of the embedding blocks and the clamping grooves; and by means of chamfering and keep-space treatment, the mold core can be taken out more conveniently.

Description

technical field [0001] The invention relates to the technical field of high-end equipment manufacturing, in particular to a mold overflow-proof glue avoidance structure. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding is achieved through injection molding machines and molds. [0003] In existing secondary injection molds, reasonable gaps are designed around the inserts without any air-avoiding structures in order to prevent overflow of glue and burrs during secondary injection around the acupuncture points where the inserts are placed. Although the above prevents the glue overflow problem of the secondary injection molding, it brings great difficulty to us to insert the plug-in, which affects the production efficiency. Therefore, we propose a mold anti-glue overflow structure. Contents of the invention [0004] The objec...

Problems solved by technology

[0004] The object of the present invention is to provide a mold anti-overflow glue avoidance structure to solve the existing secondary injection mold proposed in the background technology above. Raw edges are designed with a reasonable gap around the plug-in, without any air-avoiding structure

Although the above prevents the overflow problem of secondary injection molding, it brings us great difficulty in inserting the plug-in and affects the production efficiency.
