一种大容量塑料瓶的管胚注塑成型方法及管胚模,采用注塑成型方法,将注塑料注入由控温管胚模中注塑成型管胚,其特点在于,管胚模整体采用多流道冷却结构,管胚模芯和管胚模腔全部采用控温冷却,由控温设备对冷却介质实施温控,使得管胚模芯冷却油温温度控制在50~60℃,管胚模腔冷却油温温度控 The invention relates to a tube injection molding method and a tube embryo mold for a large-capacity plastic bottle. The injection molding method is adopted to inject the injection molding material into the injection molding tube embryo by a temperature control tube embryo mold, The cooling structure, the tube core of the tube mold and the tube cavity of the tube are all controlled by temperature. The temperature control device controls the temperature of the cooling medium so that the tube temperature of the tube core is controlled at 50-60 ° C. The tube cavity cooling Oil temperature control
