摘　　要：以汽车覆盖板的注射成型为例,运用Mold flow软件对塑件熔体填充过程、保压、熔接痕以及气穴等进行了模拟分析.设计了两种不同的冷却系统,在保证模具结构合理且完整的同时,分析其对制件的成型质量影响.对两种不同冷却系统的模拟分析数据进行比较,得出更加合理的工艺参数和模具结构,提升了塑件成型的品质,创造了更好的经济效益.Aiming at the injection forming of automobile cover plate,the position of gate and forming process of packing,weld lines and warping prediction were analyzed by using Moldflow software,and two different cooling systems were designed to compare for ensuring that the mold structure is reasonable and complete.At the same time,its impact on the forming quality of parts is analyzed.According to the comparison of the simulation data of two different cooling systems,more reasonable process parameters and mold structure are obtained,which improves the quality of plastic parts forming and creates better economic benefits.
