摘　　要：文章进一步分析和研究了气冲造型机快开阀阀门的形状及阀门上的有效流通面积,认为快开阀形状应设计成倒锥形,这样其有效流通面积大,对均匀实砂效果好。The paper further analyses the shape of the gate of quick-release valve in air impact molding machine and the effective flow area of valve gate.It is considered that the valve gate of quick-release valve should be designed as an inverted cone,and consequently the effective flow area is enlarged and even sand compaction will be benefited.
