摘　　要： 针对144腔PET瓶坯模具的结构要求,采用自然平衡法设计浇注系统,运用流变学理论计算出符合生产要求的各级流道结构尺寸,用Moldflow软件对设计结果进行模拟分析,保证塑料熔体同时到达每一个型腔,分析结果表明所设计热流道系统满足要求。 According to the structure requirements for the 144 cavity PET bottle preform mould, this paper designed gating system by the natural balance method and calculated all levels of structure size through the rheological theory in the hot runner gating system, which met production requirements. Designed results were simulated and analyzed by the Moldflow and guaranteed the plastic melt to reach each cavity at the same time. The analysis results showed that the designed hot runner system met the requirements.
