摘　　要：针对网格形状的框行薄壁塑件容易出现缩痕的问题,开展了各成型工艺参数对缩痕指数的影响研究。首先构建空调面框的Mold Flow有限元分析模型,根据材料特性和成型要求,来探讨熔体温度、模具温度、保压压力、注射时间以及保压时间等注射工艺参数与空调面框缩痕指数之间的影响规律,这为实际过程中注射工艺参数设定提供依据。Aimed at the problem that the sink marks is easy to appear in the frame thin-wallplastic products with grid, various molding process parameters on the shink mark index study iscarried out. First, the Mold Flow finite element analysis model of air conditioning plane frame isbuilt, according to the material properties and molding requirements, the influence between melttemperature, mold temperature, packing pressure, injection time and packing time for airconditioning plane frame shink mark index is explored, it provide the basis to set injectionmolding process parameters in the process of actual production.
