摘　　要： 通过对喷嘴塑件的分析,设计了一模十六腔的注塑模,并运用Moldflow对其浇注系统进行了优化设计。根据该喷嘴的结构特点,采用了一种新型的圆弧抽芯机构及辅助的开模机构。这种机构与传统圆弧抽芯机构相比,简化了模具结构,降低了生产成本,经生产实践验证设计合理。 Through the analysis of nozzle plastic parts, an injection mold with sixteen cavities was designed and the design of its gating system has been optimized using Moldflow soft-ware. A new arc core-pulling mechanism and an assistant mold opening mechanism were a- dopted according to the structural characteristics of this nozzle. Comparing to the traditional core-pulling mechanism, the new mechanism has greatly simplified the structure of the mold and reduced the production cost, which has been proved as a rational design by practical production.
