摘　　要：新型的T模成型技术可充分挖掘注塑机潜力,而目前国内对T模的应用较少。将T模技术引入塑料管件成型中,结合90°电熔弯头PE管件的结构特点设计了T模,模具结构由上下两层相同的一模双腔模具复合而成;设计了针阀式热流道系统实现交替注射与保压;设计了带气缸的T锁结构与CAM板相互配合,实现了顺序开模与抽芯。生产结果表明,采用T模成型技术可大幅缩短注塑机闲置时间,缩短单个制件生产周期。Tandem mold as a new molding technology can fully tap the potential of the injection molding machine,but the application of tandem mold is less interiorly.In this paper,tandem mold was introduced into the molding of plastic tubing coupling,and the tandem mold was designed in combination with the structural characteristics of 90°electric melting elbow PE pipe fitting.The tandem mold structure was composed of an upper and lower two-layer mold with one mold and two cavities.A needle-valve type hot runner system was designed to achieve alternate injection and holding.The T-lock with cylinder was designed to cooperate with the CAM plate to realize sequential mold opening and core pulling.The production results show that the use of tandem mold molding technology can greatly reduce the inactivity time of the injection molding machine and reduce the time cost of a single product.
