基于Moldflow的绘图板注射成形优化设计

Optimized design of the drafting board process based on the software of Moldflow

绘图板的注塑件在注塑过程中易产生翘曲变形。为此,基于Moldflow注塑模拟分析软件和正交试验方法,对不同工艺条件下的注塑过程进行了模拟分析,并运用隶属函数对分析所得的翘曲变形量进行评判。通过采用极差法分析出各因素对该塑件翘曲变形的影响程度和趋势,同时绘制因素水平影响趋势图,分析得到一组最佳的工艺参数组合方案,经过模拟验证后最终可指导绘图板注塑成形,生产出理想的绘图板产品。

The drafting board is an injected part with larger volume.This kind of product is easier to warp.So it is key to set up the injection molding process.Injection molding process of the drafting board is simulated based on different technology conditions by analysis software of Moldflow and orthogonal experiment method.The warp value is graded by using membership function.The degree and tendency induced by various factors are analyzed by using range analysis.Through analyzing the diagram of factor levels influent trend which is described according the last simulated results,the most optimized process parameters scheme is got.The conclusion of the process scheme is simulated and is used to direct the injection.
