摘　　要：建立变径管模型,并利用Moldflow对变直径管进行充填、保压、冷却、翘曲模拟分析得出最佳浇口位置与数量,结合正交实验分析了模具温度、熔体温度、充填时间、保压压力、保压时间等工艺参数对变直径管翘曲变形的影响并得到最佳参数组合;利用Moldflow验证最佳参数组合,并在此基础上设计出模具,使得生产的产品品质得到提高。The optimal gate quantity and location were obtained by a simulation using Moldflow software through a ＂filling, packing, cooling＂ scheme. A set of orthogonal experiments was carried out to obtain the optimal injection parameters for minimum warpage including melt temperature, packing time, packing pressure, filling time, and mold temperature. An injection mold was designed based on above simulation and orthogonal experiments and the quality of the Darts was improved effectively.
