摘要
介绍了用消失模铸造工艺制备液压单向阀的浇注系统与冒口设计。珠粒预发密度选取为23~26 kg/m3,采用EPS模具成型;合理控制埋型与浇注工艺参数,制得表面光洁、内壁光滑、尺寸准确的液压阀件。
The gating system and riser design in EPC process for preparing hydraulic check valves was introduced. Selecting the bead advanced density of 23~26 kg/m3, using EPS molding; reasonable controlling mold assembling and pouring process parameters, hydraulic valves with smooth surface, smooth internal wall and accurate size were obtained.
