摘　　要：介绍了汽车线束卡扣注射模实用结构及其工作过程。该模具采用侧浇口,1模4腔,卧式注射成型;利用NX12设计了塑件分型面,创新设计了型芯、型腔双边顶出以及倒扣强行脱模的结构;应用MoldFlow软件建构了冷却循环通道,对注射充填时间、冷却状况及翘曲量进行仿真分析,确定理想的注射参数指导生产。This paper introduces the injection mold structure of car wiring clip and the working principle. This mold adopts side gate, four mold cavities, horizontal injection molding;NX12 software was used to complete the parting surface design of plastic parts, and the structural characteristics of the mold with double ejection of core and cavity and forced demoulding of the undercut were innovatively designed.With the help of MoldFlow software,the pipeline circulation cooling system was created, and the filling time, cooling effect and warping deformation of plastic parts were simulated and analyzed, and reasonable injection molding parameters were obtained to guide the actual production of molds.
