摘　　要：为了解玩具汽车转向器注塑成型的最佳工艺参数,文章利用有限元分析方法,以体积收缩率、翘曲量为玩具汽车转向器质量判定指标,对熔体温度、模具温度、注塑压力、保压压力、注塑时间、保压时间等工艺参数的选择进行了分析。结果表明,在模具温度为35℃、熔体温度为200℃、注塑时间为1.5 h、保压时间为20h、注塑压力为72 MPa、保压压力为65 MPa时,玩具汽车转向器的体积收缩率、翘曲量处于最低水平.In order to understand the best technological parameters of the injection molding for toy car steering gear,in this paper,the selection of technological parameters such as melt temperature,mold temperature,injection pressure,parking pressure,injection time and parking time is analyzed by using finite element analysis melhorl with volume shrinkage and warpage as the quality judgment indexes of toy rar steering gear.Fhe results show that when the mold temperature is 35 ℃,the melt temperature is 200℃,the injection time is 1.5 h.the parking time is 20 h.the injection pressure is 72 MPa anci the packing pressure is 65 MPa,ihe volume shrinkage and warjiage of the toy rar steering gear are at the lowest level.
