The influence of pouring gate dimension on the injection forming of products was ana ˉ lyzed. A simplified structure mould with pin point gate for a cylindrical part was developed. 分析了浇口尺寸对制品成型的重要性,并针对一种圆筒形制品,设计了一种结构简单的点浇口成型模具结构。
As the results the automatic pouring rate of the sliding gate rises up to99% and the reoxidation of82B steel is greatly reduced. 并针对性地提出了解决措施,使浇铸82B钢的自动开浇率提高到99%,大大减少了82B钢的二次氧化。
