摘　　要：文章采用仿真技术对某聚邻苯二甲酰胺(PPA)控制器接线座的注塑成型过程进行模拟,并计算分析其铜片接触面的平面度。基于浇口定位算法获得最佳的浇口位置,并完成流道系统构建。初始工艺下的铜片接触面的最大平面度为0.155 9 mm,不满足设计要求,因此设计正交试验对平面度进行优化。极差与方差分析表明:对于平面度的影响程度,模腔温度为极显著,保压时间及注射时间为显著,熔体温度为不显著,优化工艺为A_(4)B_(1)C_(3)D_(4)。优化工艺下制件的最大平面度为0.089 8 mm,优化率达到42.4%,达到设计要求,且填充状态良好,实际试模结果也验证了优化工艺的可行性。The injection molding process of a polyphthalamide(PPA) controller wire holder was simulated by using simulation technology and the flatness of its copper contact surface was calculated and analyzed.The optimal gate position was obtained based on the gate positioning algorithm and the construction of the runner system was completed.The maximum flatness of the copper contact surface under the initial process is 0.155 9 mm,which does not meet the design requirements.Therefore,an orthogonal test is designed to optimize the flatness.The range and variance analysis show that the influence of the cavity temperature on the flatness is extremely significant,the holding time and the injection time are significant,the melt temperature is not significant,and the optimized process is A_(4)B_(1)C_(3)D_(4).The maximum flatness of the part under the optimized process is 0.089 8 mm,the optimization rate reaches 42.4%,which meets the design requirements,and the filling state is good.The actual test results also verify the feasibility of the optimized process.
