挡圈双顶杆板半热流道注射模设计

Design of Half Hot Runner Injection Mold With Big Ejector Sleeves for the Check Rings

以挡圈注射模设计为例,分析了该类塑件注射模设计的特点,说明了利用大司筒(套筒)顶出解决顶出问题的设计原理,介绍了大司筒顶出模具的结构形式、适用场合以及设计要点,展示了如何设计大司筒模具才能延长模具寿命。为从事模具设计的人员合理地确定精密高效长寿命模具的设计方案提供借鉴。

Take check ring injection mold for example, to analyzed the characteristics of mold design of these kinds of parts.This article showed the design principle by using big ejector sleeves to solve parts ejector, and to introduce the structure of big ejector sleeves, applications and major design points. And shows how to design big ejector sleeves to extend the life of the mold. It provides a reference for mold designers in designing precise mold.
