摘要
以注塑成型为基础,采用数值模拟和回归正交试验设计相结合的方法,建立了手机面框注塑成型过程中熔体温度、注射时间、速度/压力切换、保压时间、保压压力与翘曲变形之间的回归方程,得出各注塑工艺参数对塑件翘曲变形的影响规律,并通过回归方程进行了翘曲变形回归预测,从而确定工艺参数的最优组合。结果表明：由该回归方程建立的数学模型非常显著,回归预测结果可信度高。
Based on injection molding, regression equation relationship between warpage and melt temperature, injection time, V/P switch, holding time and holding pressure was established for injection molding process of the mobile phone frame using the method of numerical simulation and orthogonal regression design. The effect rules of process parameters on the warpage were obtained, the regression equation was applied to predict the warpage, the optimum combination of process parameters was determined. The results show that the regression model is very signifi cant and the regression prediction results are highly reliable.
