摘要/Abstract

摘要： 对车窗内饰件三维模型，利用NX12.0软件进行分析，设置了热流道浇口位置。选取模具表面温度、熔体温度、顶出温度、冷却时间为研究对象，利用正交试验法结合极差分析法，得出模具表面温度60 ℃、熔体温度260 ℃、顶出温度82 ℃、冷却时间30 s时，车窗内饰件的翘曲率最小，为1.45 %；对K3H3J2I3组参数进行试验验证，试验结果表明，车窗内饰件外观质量良好，观察不到翘曲现象，佐证了Moldflow 2018有限元分析数据的准确性；极差分析法的合理性。

关键词: 模具表面温度, 熔体温度, 顶出温度, 冷却时间, 正交试验

Abstract: A 3D model for window interior decoration was analyzed to determine the position of hot runner gate by the NX12.0 software, and the die surface temperature, melt temperature, ejection temperature and cooling time were selected as research objects. The mold surface temperature was determined as 60 ℃, the melt temperature as 260 ℃, the ejection temperature as 82 ℃, and the cooling time was determined as 30 s by means of the orthogonal test and extreme difference analysis method. A minimal warping rate of 1.45 % was achieved for the window interior trim. The group parameters of K3H3J2I3 were tested and verified. The test results indicated that the appearance quality of the window interior trim was fine, and there was no warpage phenomenon observed. This proved the accuracy of Moldflow 2018 finite element analysis data and the rationality of extreme difference analysis method.

Key words: mold surface temperature, melt temperature;ejection temperature;cooling time;orthogo-nal test
