| 摘 要： | 运用正交试验,通过Moldflow模拟分析,将模拟分析样条与实际注塑成型微样条进行对比,研究了模具温度、熔体温度、保压时间、保压压力、注射压力工艺参数对注射成型制品翘曲变形的影响。通过微型样条模具进行成型实验,用三坐标测量仪对成型制品的翘曲变形进行了测量,结果表明,保压压力和熔体温度对样条翘曲变形的影响较大,实际注塑成型样条的翘曲变形量比模拟分析的翘曲变形量大,拉伸样条模拟数值与实际的平均差值为0.205mm,实际值比模拟值增大了约50%;冲击样条的模拟数值与实际数值的平均差值为0.2405mm.

| Abstract: | The warpage parts were analyzed by Moldflow simulation and actual injection molding. The effects of mold temperature, melt temperature, packing time, packing pressure and injection pressure on warpage of injection molding parts were studied by orthogonal test. The injection molding process was tested by micro spline mould. The warpage parts of molding were measured with a three-coordinate measuring machine. The results showed that the packing pressure and melt temperature had important effects for warpage of parts. The warpage of actual injection molding was bigger than that of simulation test. The average error of tensile specimen was 0. 205 mm, the actual value increased by 50% compared with simulation test. The average error of impact specimen was 0. 240 5 mm. |
