Improved injection mold structure

Abstract

The invention relates to the technical field of molds, and discloses an improved injection mold structure which comprises connecting sleeve rods and a supporting top plate. The connecting sleeve rodsare fixedly installed on the left side and the right side of the bottom of the supporting top plate, and supporting springs are fixedly installed at the bottoms of the inner walls of the connecting sleeve rods. According to the improved injection mold structure, baffles are arranged, a valve is opened to enable injection molding materials in a heating box to flow into an injection molding shell through a liquid injection pipe for injection molding, a lifting transverse plate compresses the supporting springs along with increase of the injection molding materials gathered in the injection molding shell, so that supporting stand columns on the lifting transverse plate move downwards to pull the baffles on the left side and the right side to move relatively, the flow of the liquid injection pipe is reduced, the lifting transverse plate moves downwards till the supporting springs are completely compressed, then the liquid injection pipe is completely closed, quantitative injection moldingis achieved, the situation that injection molding is too much or too little is avoided, and the injection molding efficiency of a mold is improved, so that use is more convenient.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an improved injection mold structure. Background technique [0002] Molds, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting and stamping to obtain the required products, in short, molds are tools used to make shaped objects , This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object through the change of the physical state of the formed material, known as the "mother of industry". [0003] Existing molds rely on manpower to close the valve to stop injection molding during injection molding, which is prone to more or less injection molding. It is necessary to clean up the overflowing injection molding materials or continue to add injection molding materials, which greatly reduces the cost of mold...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an improved injection mold structure, which has the advantages of convenient injection molding, and solves the problem that when the existing molds perform injection molding, they all rely on manpower to close the valve to stop injection molding, which is prone to injection molding problems. In more or less cases, it is necessary to clean up the overflowing injection molding material or continue to add injection molding material, which greatly reduces the efficiency of mold injection molding and is very inconvenient to use
