摘　　要：介绍了共注成型工艺及设备工作原理,并将其应用于多色仪表盖的成型与模具设计中。通过对塑件材料及结构的工艺性分析,采用多色多模清色注塑方式,布置一模六腔两个模位两个不同的浇注系统,实现1个成型周期中多种色彩塑料3个塑件的同时注射,并利用转盘机构与偏心顶出机构实现先后两个模位成型多色仪表盖并顺利脱模的过程。The principle of co-injection molding was illustrated and was applied to the injection procedure for the multi-color meter lid. Based on the material characters and the structure analysis of the part, a set of multi-color and multi-component injection mold with two different gating systems composed of six different dimensioned cavities was developed, which could fill three lids in the different cavities with different kind or different color plastics simultaneously. This set of mold could exchange the position of two cavities and strip the lids successively by a rotary mechanism and a eccentric mechanism.
