AI Technical Summary

Technical Problem

Existing injection molds are prone to gaps during the mold closing process, causing molten plastic to flow out, resulting in defective products, and making demolding difficult.

Method used

The design employs a guide rod and a magnetic block, utilizing the interaction between the magnetic block and the coil to generate induced current and induced magnetic field, providing a buffering effect to prevent gap formation, and achieving rapid demolding through a one-way valve and air vent design.

Benefits of technology

It effectively reduces the defect rate of injection molded products, improves the efficiency of mold closing and demolding, and reduces the difficulty of manual operation.

Abstract

本申请涉及注塑模具技术领域,尤其是涉及一种塑胶件注塑模具,包括静模和动模,静模上安装有导向杆,动模上设有导向孔,导向杆靠近动模的一端安装有磁性块,导向孔的底部设有可导电的线圈,线圈由螺旋线环构成,螺旋线环首尾相连形成导电的闭环。本申请通过在导向孔的底部安装闭合的线圈,使在动模与静模进行合模的过程中,磁性块靠近线圈时,使线圈切割磁感线,产生感应电流和与磁性块磁场方向相反的感应磁场,从而达到缓冲的作用,另外当动模与静模合模之后,感应磁场消失,磁性块不再受线圈的作用力,使动模与静模之间不容易产生间隙,而减少出现次品的概率。
