摘　　要：采用析因设计实验的方法,对模腔压力数据进行采集,研究了不同阶段模腔压力的变化规律曲线,分析了模腔压力与注塑制品质量的关系。结果表明,模腔压力直接决定着制品质量,充模阶段模腔压力上升情况对制品性能的影响较大,其次是冷却阶段的模腔压力下降情况。The transform regulation of cavity pressure in each injection stage was studied through the cavity pressure data obtained from factorial experiments. The relationship between cavity pressure and product quality in different stages was analyzed. The results demonstrated that product quality had a strong relationship with cavity pressure. Both the increase of cavity pressure in mold filling stage and decline of cavity pressure in cooling stage had influence on product quality while the former being more important.
