设计简介
摘 要
本设计是骨架注塑模，特点为薄壁骨架，采用材料为聚苯乙烯，模具采用延时弯销机构，产品自动脱落，无需顶出板。这样使模具结构更简单化，重量减轻，而且省材。工作过程为：塑料粉末送至料斗，开始加热，加热温度为265——500F之间。模具闭合，螺杆前行在压力作用下熔融塑料进入模具型腔。注塑完毕，动模具后退，模具打开，产品落下。模具闭合，由复位杆复位，准备下一次的注塑。

Abstract
This topic is injection mold for framework. The charactoristice is a thin wall framework. PS are use by this plastics .This mold adoption bend to sell the organization. The part may be down off and don’t need ejector plate and ejector retainer plate. This make the stmcture of the mold turned more simple,the weight ease ,and the provinle material. Plastic powder is loaded into the feed hopper and a centain amount feed into the heating chamber when the planger draws back. Heating temperatures range from 265to500F. After the mold is closed the plunger moves forward ,forcing some of the fluid plastic ynto the mold cavity under pressures. When this over ,the part may be down off when the mold opens. Returns the ejector plate back to its original podition when the mold is colsed. And ready for next.
