摘要
以空调遥控器的电池壳和底壳为对象,利用Moldflow进行有限元网格划分,建立流道和冷却系统;选择模温、料温、保压力、保压时间和注射时间这5个工艺参数为研究对象,以不对称薄壁注塑件的最小收缩和翘曲为目标,利用Taguchi法建立L16正交试验表,并通过信噪比和方差分析,研究各个因素的权重,得到最优的工艺组合,并对优化目标最小值进行预测,最后通过模拟来验证优化组合。结果表明:影响体积收缩和翘曲的最主要因素为料温和保压力,进而验证试验优化的可靠性。
Taking air conditioning remote control battery Moldflow software was applied to establish finite element meshing, the minimum shrinkage and warp of asymmetry shell products, shell and bottom shell for example, the the runner and gate system. In order to get the mold temperature, melt temperature, holding pressure, holding pressure time and injection time such five process parameters were selected, the L16 orthogonal tables was established using Taguchi method, the signal-to-noise （S/N） and the analysis of variance were used to find the optimum levels and to indicate the impact of the process parameters on shrinkage and warpage. The minimum of shrinkage and warpage was predicted. Finally, a verification test was also performed to prove the effective of the optimum levels of process parameters results showed the important factors which affect shrinkage and warpage were melt temperature and holding pressure. It can be inferred that Taguchi optimization was reliable.
