摘要: 针对汽车档位杆注射成型过程中的各类质量问题缺陷,选取翘曲变形量为优化目标,运用正交试验设计方法借助Moldflow软件研究模具温度、熔体温度、注射时间、保压压力和保压时间等试验因子和试验指标翘曲变形间存在的关系,找出各因子对档位杆翘曲变形影响程度的排序和最佳的工艺因素水平组合,再进行数值模拟验证及现场试模验证,从而达到提高档位杆产品注塑质量和缩短生产周期的目的。

Abstract: Aiming at various quality defects in the injection molding process of automobile gear lever, the warpage was selected as an optimization objective. The relationship between the experimental factors of mold temperature, melt temperature, injection molding time, packing pressure and holding time and the warpage deformation as experimental index were studied by means of the Taguchi experiment design method and Moldflow software. The order of influence degree for each factor on the warpage deformation of gear lever as well as the optimum combination of factors and levels were found. Then numerical simulation and injection molding were carried out to verify the validity of these results. As a result, the goal for improving the injection quality and shortening the production cycle of gear lever products was achieved.
