| 摘 要： | 在注塑成型过程中，保压阶段对制品的性能有重要的影响。以音箱面板为研究对象，运用Moldflow模拟分析软件，采用恒定压力、阶梯下降、阶梯上升、线性下降、线性上升等五种保压方式，分析了不同保压方式对音箱面板体积收缩率与翘曲变形的影响。研究发现恒定压力保压方式下音箱面板体积收缩率与翘曲变形最小，阶梯下降、线性递减、线性递增则次之，阶梯上升则最大。

| Abstract: | In the injection molding process, packing stage has a significant impact on performance of injection product. This paper uses sound box pand as study object, applies Moldflow simulation software, adopts five different packing ways including constant packing, step declining, step rising, linear declining and linear rising and analyzes influence of different packing ways on sound box panel volumetric shrinkage and warpage. It is found that sound box panel under packing way with constant pressure has the smallest volumetric shrinkage and warpage, then step declining, linear declining, linear rising, and step rising is the maximum. |

| Keywords: | packing Moldflow volumetric shrinkage warpage numeric simulation |
