摘要
以智能扫地机翻盖为例,使用Moldex3d模流分析软件对薄壁复杂型零件进行注塑优化分析,首先通过对比两浇口与四浇口两种进胶方式,得出较优进胶方式为两浇口进胶;再进行正交实验分析,得出最佳注塑工艺组合为保压时间7s,保压压力50%,熔体温度220℃,模具温度50℃。同时得出,影响制件翘曲变形的主次因素为保压压力、熔体温度、保压时间、模具温度。最后通过优化保压曲线,得到最佳的注塑工艺,制件的翘曲变形量由原来的2.482mm下降至1.369mm,降低了44.8%。
Taking an intelligent sweeper clamshell as an example,the Moldex3d mold flow analysis software was used to optimize the injection molding of thin-walled complex parts.A two-gate mode was recommended for the better glue feeding method through comparing the two-gate and four-gate glue feeding methods.Based on the orthogonal experimental analysis,the optimal injection molding process combination was determined to be a packing time of 7 s,a packing pressure of 50%,a melt temperature of 220℃,and a mold temperature of 50℃.Meanwhile,the main and secondary factors affecting the warping deformation of the parts were determined as the packing pressure,melt temperature,packing time,and mold temperature.Through optimizing the packing pressure curve to obtain the optimal injection molding process,the warpage deformation of the parts was reduced by 44.8%from 2.482 mm to 1.369 mm.
