摘　　要：针对汽车车灯厚壁件成型周期长的问题,介绍了双色注射成型厚壁件的方法及设计要点,通过对厚壁件进行分层,减小壁厚以达到缩短冷却时间的效果,提高生产效率的同时提高塑件成型合格率。Aiming at the problem of long moulding cycle of thick wall parts of automobile headlights,the method and design key points of two-color injection moulding thick wall parts were introduced.By laminating the thick wall parts,the wall thickness was reduced to shorten the cooling time,the production efficiency and the pass rate of plastic parts were improved.

关 键 词：厚壁件 分层注射 成型周期 双色注射模
