Optimization Analysis of Warping of Injection Molding Process of Pipeline Distributor Based on Moldflow
管道分路器所用材料为聚酰胺66(PA66),通过注塑成型工艺制得,通过Moldflow软件对其进行模流分析,注塑成型过程受到很多因素影响,本文以熔体温度、注射压力、保压压力以及冷却时间为研究变量,以制件的翘曲变形量为研究目标建立响应面模型,通过获取较佳的成型工艺参数组合,从而降低制件的翘曲变形量。结果表明:当熔体温度为238 ℃、注射压力为50 MPa、保压压力为30 MPa、冷却时间为110 s时,制件的翘曲变形量最小,为2.264 0 mm,较未优化前降低了2.118 7 mm,整体质量显著提升。
The material used for the pipeline distributor is polyamide66 (PA66), which is made by injection molding process and analyzed by molding flow by Moldflow software, and the injection molding process is affected by many factors. In this paper, the melt temperature, injection pressure, holding pressure and cooling time are taken as the research variables, and the warpage deformation of the parts is taken as the research objective to establish the response surface model, so as to reduce the warpage deformation of the parts by obtaining a set of better combinations of molding process parameters. The results show that when the melt temperature is 238 ℃, the injection pressure is 50 MPa, the holding pressure is 30 MPa and the cooling time is 110 s, the warpage deformation of the parts is 2.264 0 mm, which is reduced by 2.118 7 mm compared with before optimization, and the overall quality is significantly improved.
