基于CAE分析的鼠标外壳注塑模具设计

摘要

鼠标外壳塑件结构复杂,在确定其模具设计方案时,进胶位置仅凭经验难以确定.以三维设计软件NX为平台,通过分析鼠标外壳的结构和功能特点,采用Mold flow进行模流分析,以确定其最佳进胶方案,并据此设计了整体模具结构,所采用的斜顶抽芯机构能够灵活处理成型产品中的对称扣位.实践证明,所设计的鼠标外壳注塑模具结构紧凑,工作稳定,成型容易,精度保持性好.%The structure of the mouse shell is complex,so it is difficult to determine the location of the gate only by experience when designing the mould.This paper analyzed the structure and function of the mouse shell based on the three-dimensional design software NX,and the best gate location was determined by Moldflow analysis.So the side core pulling mechanism can flexibly handle the symmetrical snap joints of the product.The mould was designed for compact structure,working stability,easy manufacturing,and high precision.
