摘　　要： 基于Minitab软件建立6因素5水平的田口试验并与模糊数学中的综合评判法相结合,以电脑显示器外壳为研究对象,对不同工艺条件下的注塑压缩成型过程进行模拟分析,对塑件成型后的最大翘曲变形量、平均熔接线和平均体积收缩率等3个目标值进行综合评判。通过对综合评分进行极差分析,确定了模具温度、熔体温度、压缩力、压缩速度、压缩距离和压缩时间等对注塑压缩成型的影响程度,得出了最优注塑压缩成型工艺参数组合方案,并对该工艺参数组合方案进行了模拟验证。最终得出最优工艺参数:模具温度为75℃,熔体温度为260℃,压缩力为60 t,压缩速度为14 mm/s,压缩距离为1.5 mm,压缩时间为7 s。 The Taguchi test of 6 factors and 5 levels was set up in this paper based on Minitab and combined with the comprehensive evaluation method in fuzzy mathematics.The simulation analysis of the injection compression molding process under different process conditions was carried out.The target values of the maximum warpage change,the average weld line and the average volume collection after the plastic parts are formed were evaluated to get comprehensive scores.The influence of the technological parameters of mould temperature,melt temperature,compression force,compression speed,compression distance and compression time on injection compression molding were determined through range analysis of the comprehensive scores,and the optimal combination scheme of injection compression process parameters was drawn up and the combination scheme of the process was simulated.Finally,the optimal process parameters were obtained as follows:die temperature was 75℃,melt temperature was 260℃,compression force was 60 t,compression speed was 14 mm/s,compression distance was 1.5 mm,compression time was 7 s.
