摘　　要：利用Moldflow软件对注射器塑料件的翘曲原因进行分析,并采用正交试验设计方法(单参数变动实验)对保压压力、熔体温度、模具温度、冷却时间等进行分析。经分析后得出影响制品翘曲变形的最主要因素是保压压力,其次则是熔体温度、模具温度、冷却时间。模拟得到本例最优成型参数分别为,模具温度35℃、熔体温度240℃、保压压力100MPa、保压时间17s、冷却时间20s。The warp of injection mouled part was analyzed by using Moldflow software. The packing pressure,melted mass temperature,mold temperature and cooling time were also analyzed by using orthogonal experiment method. The analyzing results indicated that the most important factor affecting the warp of injection mouled part was packing pressure, next were the melted mass temperature, mold temperature, cooling time, The best forming parameters were as follows ：mold temperature 35℃ ,the melted mass temperature 240℃ , pressure 100MPa,the packing time 17s,the cooling time 20s.
