摘 要
本文主要介绍了当前国内外模具发展现状，以及模具零部件结构与功能系统设计。主要包括成型零部件的设计、浇注系统设计、排气系统设计、脱模机构设计、侧向抽芯机构设计、合模导向机构设计、冷却系统设计。
由于塑件特殊结构，为便于脱模，设计中采用拉钩式顺序分型机构和斜导柱抽芯机构，加大了模具结构复杂程度。塑件上部分孔的成型采用凸、凹模组合成型巧妙解决了侧抽芯问题。
关键词：注塑模；浇注系统；分型面；斜导柱
Abstract
This paper mainly introduce the development of mould in our country and foreign countries, structure of parts of mould ,and design process of function system .Including process of air ejection system, ejection mould system, structure of slanting pillar ,assemble system ,cooling system.
Because of plastic product special figure, the mould use sub-type tamp-pillar pumping core institution ,which increases the complexity of the structure .The forming of the hole on beside parts use crippling mould and concave mould ,which cleverly solves the problem of side core pulling.
Key words: injectiong mold pouring system dividing surface helix-pillar
