摘　　要：分析了采用传统热流道注射成型的大型边框制品的缺陷,针对其熔接痕问题,利用Moldflow软件,采用多浇口顺序控制技术对其填充过程进行优化,通过数值模拟研究发现,采用顺序控制注射技术控制各个浇口的开启时间,能切实有效地消除制品的熔接痕,提高制品的质量。The defects in the traditional hot runner injection molding of a frame product were analyzed. In order to solve the problem of weld lines, the frame product was optimized by using the method of sequence control. Through Moldflow simulating, the re- sults showed that controlling the gate opening time while applying sequence control technology, could effectively eliminate weld lines and improve the quality of products.
