| 摘 要： | 针对洗衣机底板在注射成型中产生的翘曲问题,利用CAE软件进行计算机数值模拟。结果表明影响翘曲变形的主要因素为收缩不均,并分别通过二级保压方式和根据材料的PVT曲线进行等比容保压来减小翘曲,对比两种保压方式,后者得到的塑件的翘曲量更小。

| Abstract: | In order to minimize the warpage of the bottom plate of washing machine during injection molding,the computer numerical simulation is performed by CAE software.The result revealed that the major factor influenced the warpage was uneven shrinkage.Two packing ways was used to reduce the warpage,that was two level packing and constant specific volume packing based on the PVT curve of the material.Compared of the two ways of packing,the warpage of plastic parts was smaller by the the latter one. |
