摘　　要：分析了有侧凸凹且型腔较深塑件的工艺特点,介绍了该类塑件的模具二次顶出同时强制脱模的典型结构的应用范围及工作原理。给出了有侧凸凹且型腔较深塑件二次顶出同时强制脱模的几个典型案例,为类似零件在模具设计中的应用提供了参考。The technical characteristics of deep plastic parts with side convex-concave structures were analyzed. The application and working principle of the typical structure in injecting such kind of parts was introduced, which combined the two-stage ejection with forced demolding. Several typical examples were presented to provide reference for die design of similar parts.
