摘要
提出一种最小化制品翘曲的注塑工艺参数优化集成方法.以空调柜机顶盖注塑制品开发为例,该方法使用Moldflow软件分析制品的翘曲变形,运用田口方法确定与制品翘曲量密切相关的工艺因素,然后采用响应曲面法(RSM)和改进的精英保留自适应遗传算法(EAGA)相结合的方法,建立主要影响工艺参数与制品翘曲量之间的关系模型,通过对模型寻优以实现对制品翘曲的优化.该方法的适用性在制品的实际生产中得到了验证.
In this paper,an integrated optimization method was proposed to minimize warpage.An air-condition top cover was taken as an example in the research of warpage optimization of injection molding.Molflow software was used to analyze the warpage deformation of the injection-molded parts,and the significant process parameters influencing warpage were determined using FE analysis results based on Taguchi method.Then a predictive model for warpage index was created and the optimum process parameter values were solved by combining response surface methodology（RSM） and an effective genetic algorithm（GA） improved by using self-adaptive and elitism strategies.The actual production shows that the optimization method proposed is feasible and effective in processing plastic part.
