以电池后盖为例,利用Moldflow进行注塑CAE分析。首先完成网格划分、创建浇注系统、设定材料和成型工艺参数等分析前处理,并做流动分析。以缩痕深度、体积收缩率为质量目标,模具温度、熔体温度、注射时间、保压压力、保压时间等为工艺参数,进行DOE(Taguchi)试验,结果表明:保压压力影响最大,模具温度、熔体温度次之,保压时间影响最小。优化成型工艺参数后,缩痕指数下降0.82%,体积收缩率下降0.815%,熔接痕减少,塑件质量得到提高。
Take the battery back cover as an example, use the Moldflow for CAE analysis. First, meshing is completed, the casting system is set up, the pre-treatment of setting material and molding process parameters is done, and the flow analysis is done. DOE (Taguchi) test was carried out with shrinkage depth, volumetric shrinkage rate as the quality target, mold temperature, melt temperature, injection time, packing pressure and dwell time as the process parameters. Mold temperature, followed by the melt temperature, dwell time the least affected. After optimizing the molding process parameters, the shrinkage index decreased by 0.82%, the volume shrinkage decreased by 0.815%, the weld lines reduced and the quality of plastic parts improved.
