【摘要】 分析了注塑制件翘曲的原因,采用著名的CAE软件Moldflow与正交试验方法,对不同工艺条件下的注塑成型过程进行模拟分析并对正交实验数据进行极差分析,确定注射时间、保压压力、保压时间、冷却时间、熔体温度、模具温度以及冷却液温度等注塑成型工艺参数对制件翘曲变形的影响程度,得出最优的注塑成型工艺参数组合,并以一薄壁导光板对该工艺组合方案进行模拟验证与实际注塑实验验证。更多还原

【Abstract】 This article analyzes the factors of warpage,using Moldflow and orthogonal experiment to simulate the injection molding process with different technology parameters,and using range analysis way to gain the different effect degree from injection time,holding pressure,holding time,cooling time,melt temperature,mold temperature and the coolant inlet temperature to the warpage of injection molding part,getting the optimality injection molding parameters,and using CAE simulation and experiment to verify the parameters with a thin-wall light guide plate.更多还原
