【摘要】 以手机外壳为例,应用CAE软件模拟了注塑件的注塑成型过程。通过正交试验方法与模拟仿真实验的结合,对注塑成型的填充、保压、冷却和翘曲变形过程进行仿真实验分析,获得了制件不同条件下的翘曲变形值。并通过对试验数据的极差分析,得到了不同工艺参数对注塑过程翘曲变形的影响程度,进而得到一组优化的工艺参数组合,同时对优化后的工艺参数组合进行仿真模拟分析,得到了符合产品要求的翘曲变形量,为同类制品的工艺参数优化提供了依据。更多还原

【Abstract】 Taking mobile phone shell as research object,the injection molding process is simulated by using CAE software. By combining with the simulation experiment and orthogonal test method,the different warping deformation result table from the numerical simulation of injection molding is got. And based on range analysis of experimental data,the influence degree of different process parameters on the warping deformation is got,then the optimal combination of process parameters is gained,and the warping deformation conform meets product requirements,which provides a basis for the process parameters optimization of similar products.更多还原
