摘要: 以塑件最小体积收缩量为优化目标,以模具温度、保压时间、保压压力和熔体温度为优化变量,采用BOX(BoxBehnken Design)二阶响应曲面法,结合方差分析技术,建立了高适配性体积收缩响应面优化模型,进而优化得出了最优工艺参数组合,通过计算机辅助工程(CAE)分析与成型实验验证,验证表明塑件的体积收缩量减少约8 %左右,满足塑件高精确装配要求,证明了研究工艺优化技术方法的可行性和可靠性。
Abstract: A high adaptable optimization model of volume shrinkage response surface was formulated with minimum volume shrinkage of plastic parts as the optimization goal, mold temperature, packing time, packing pressure, and melt temperature as the optimal variables. Using Box(Boxbehnken design) secondorder response surface design method, combine variance analysis, optimal process parameters were obtained. CAE analysis and prototyping experiments confirmed that these optimal parameters could decrease contraction by 8 %.
