摘要
以汽车右A柱下饰板作为研究对象,进行正交模拟试验,探讨不同注塑参数对下饰板翘曲变形的影响,模拟结果表明:影响翘曲变形最显著的因素是熔体温度、保压压力;其次是冷却时间、注射时间;翘曲变形几乎不受模具温度、保压时间的影响;确定了下饰板成型的最佳工艺参数组合,在该工艺条件下注塑A柱下饰板翘曲变形量减少到2.206 mm,实际生产与模拟结果相符。
Taking the automobile lower plaque for Right-A-pillar as examples,L27orthogonal experiment are applied to the studies on the influence law on warpage deformation under different process parameters.The results show that the packing pressure and melt temperature have the greatest influence on warpage deformation;cooling time and injection time have the general influence;other parameters on the warpage deformation influence almost can be ignored.Optimal combination of processing parameters is obtained,by which the minimum warpage of the parts is reduced to 2.206 mm.Actual production is basically consistent with the simulation result.
