摘　　要：基于均匀试验设计,研究注塑工艺参数对热流道注塑模具下ABS注塑制品的翘曲变形的影响,并基于Moldflow和MATLAB软件对翘曲变形模型进行预测、分析和计算。试验结果表明:基于多因素试验方法,能够有效预测翘曲变形的回归模型;翘曲变形量影响程度由大到小的排序为注射时间、冷却时间、注射温度、保压时间、保压压强,并利用遗传算法得到注塑最佳工艺参数。Based on the uniform test design,the influence of injection molding process parameters on the warp deformation under the hot runner injection mold products made by ABS was studied.And the warpage deformation model was predicted,analyzed and calculated based on Moldflow and MATLAB.Experimental results show that the regression model of warping deformation can be predicted effectively based on the multi-factor test method.The results indicated that the descending sequence of influence factors on warpage deformation is as follow:injection time,cooling time,injection temperature,holding time,holding pressure.And the optimum process parameters of injection molding were obtained by genetic algorithm.
