摘　　要：以某轿车门内饰板为例,对汽车门内饰板成型的翘曲变形问题进行了研究,基于Moldflow,对其浇注系统进行了改进,使翘曲降低9.23%;采用Minitab对其工艺参数进行正交优化,得到各参数对翘曲变形影响的重要性为:保压时间>熔体温度>保压压力>模具温度。模具温度30℃,熔体温度230℃,保压时间10 s,保压压力40 MPa为最优工艺参数组合,可使汽车门饰板翘曲降低8.5%。采用改进的浇注系统和优化的工艺参数,可使汽车门饰板的翘曲降低17.73%。Taking a door trim panel as an example, the warping problem of forming performance of automobile door trim panel was studied, Based on Moldflow, the pouring system was improved, reducing the warping by 9.23%. Its process parameters were optimized by the orthogonal experiment based on the Minitab, it was found that： the importance of various parameters on the buckling deformation is： holding time 〉 melt temperature 〉 holding pressure 〉mold temperature; the optimal combination of forming process parameters as following： the mold temperature 30℃, the melt temperature 230℃, the holding time 10 s, and the holding pressure 40 MPa, which can reduce the warping problem of door trim panel by 8.5%. Thus, with the improved pouring system and the optimal process parameters, the warping of car door trim panel is reduced by 17.73%.
