Mold combining mechanism of injection machine

Abstract

The invention relates to a mold combining mechanism of an injection machine. According to stress situation analysis on a front mold plate and a moving mold plate in mold combination operation of the injection machine, overall structures of the front mold plate and the moving mold plate are optimally designed, mold combination force to the two mold plates can be converted through a novel mold platestructure, and the purposes of improving the rigidity of the mold plates and the mold combination precision are achieved. The front mold plate and the moving mold plate comprise a mold locking forceloading plate, an annular hollow arch and a mold mounting plate; the top of the annular hollow arch support structure is fixedly connected with the mold locking force loading plate and the bottom of the annular hollow arch support structure is fixedly connected with the mold mounting plate; the front mold plate structure is hollowed, so that the mass of the mold plate is reduced while the mold plate rigidity is ensured. The mold combining mechanism has the advantages that firstly, the sealed hollow structure of the front mold plate and the moving mold plate is high in rigidity, high in material utilization rate and low in manufacturing cost; secondly, through the arch support structure of the front mold plate and the moving mold plate, the mold locking force and the counteraction force ofthe mold can be counteracted, furthermore the mounting plate stress deformation can be reduced, and the injection precision can be improved.

Description

technical field [0001] The invention relates to the field of injection molding machines, and is a high-elastic mold clamping mechanism optimized and designed by analyzing the force of a front template and a movable template, which is used to improve the force deformation of the mold during mold clamping and improve the injection molding precision of products. Background technique [0002] The structural design of the front platen and movable platen of the mold clamping mechanism of an injection machine directly affects the quality and manufacturing cost of injection molded products. The structural form of the template determines the force and deformation of the template and the mold installed on it when the mold is closed. Ensuring that the deformation of the mold is small when the mold is closed is the basic guarantee for high rigidity and high-precision injection molding. [0003] In the mold clamping mechanism, the mold clamping oil cylinder pushes the movable template fo...

AI Technical Summary

Problems solved by technology

The mold clamping mechanism needs to provide greater clamping force to meet the mold locking requirements, and the uneven pressure on the mold can easily cause poor exhaust, thus affecting the quality of injection molded products. In addition, the uneven distribution of long-term clamping force is not conducive to protecting the mold
