| 摘 要： | 对CAE分析的收缩结果进行了评述。给出了利用不同收缩率确定型腔关键尺寸的方法。考虑了模具受热膨胀和型腔压力对型腔尺寸的影响。利用Moldflow预测成型时的型腔压力,并用AN-SYS计算型腔压力导致的尺寸变化,给出了分析实例,为精密注塑成型模具型腔尺寸的确定提供了依据。

| Abstract: | The shrinkage results of CAE analysis are elaborated.The method of determining critical cavity dimensions with different shrinkages is given.The effects of mold heating expansion and (cavity) pressure on cavity dimension are considered.The pressure in mold is predicted by Moldflow.(ANSYS) is used to calculate dimensional changes caused by mold pressure and an instance is given.(It's) a foundation for determining the cavity dimensions of precise injection mold. |
