摘　　要：注塑制品的变形影响产品的最终形状和尺寸精度。通过模拟注塑成型过程,并结合田口实验设计法,研究了工艺参数与注塑制品翘曲变形的关系,得到了优化的工艺参数。在此基础上,进一步研究了模具温度、熔体温度、注射时间和保压压力等各工艺参数对变形的影响。The deflection of injection products influences final shape and dimensional precision： Through the numerical simulation of injection process, and combined with Taguchi experimental method, the relation between processing parameters and the warpage of injection products is studied. The optimal processing parameters are obtained. Based on this, the effects of mold temperature, melt temperature, injection time and holding time on deflection are discussed further.
