矿灯凸透镜注射模设计及成型工艺

Design of Injection Mold and Moulding Process for the Miner's Lamp Convex

通过对矿灯透镜产品结构分析,以及注射成型存在问题点,确定了该类塑件的注塑模具结构,以及模具工作过程。其特别之处在于采用灵活的预压杆机构对产品超厚部分进行二级保压,解决了矿灯凸透镜部分容易产生收缩和真空泡等问题。

Over the analysis to miner＇s lamp convex structure, and the problems existed in injection mold, injection mold structure of this kind of plastic parts and its working process are defined. It specially uses flexible pre-pressing pole mechanism to do second packing to the extra thick wall, so as to solve the miner＇s lamp convex problems including shrinking and vacuum bubble.
