摘　　要：分析了L形内侧固定卡脚的结构特点和成型工艺,阐述了1模8件的设计方案以及定、动模镶块和主要电极的设计要点,介绍了模具的工作过程。针对塑件上下对称的特点,采用镜像排布型腔的结构形式,使得模具结构紧凑,节约了模具材料,减轻了模具重量,缩短了主流道的长度和塑件的成型周期,在很大程度上提高了塑件的质量。经批量生产验证,塑件的尺寸精度高,注射成型工艺过程稳定可靠。In the first mock exam,the structural characteristics and molding process of the L shape inner fixing pin are analyzed.The design plan of 8 modules and the design points of the fixed and dynamic mold insert and main electrode are described.The mold working process is introduced.According to the characteristics of symmetrical upper and lower parts of plastic parts,the structure of mirror arrangement cavity is adopted,which makes the mold structure compact,saves the mold material,reduces the mold weight,shortens the length of the main channel and the molding cycle of the part,and improves the product quality to a great extent.The mass production proves that the dimensional accuracy of the parts is high,and the injection molding process is stable and reliable.
