摘要

某大型球墨铸铁水阀

采用树脂砂型铸造工艺进行生产

选取芯盒精密组芯进行造型

采取双层阶梯式浇注系统

冒口采用"全冒口设计"

通过增加冷铁来消除水阀内部缺陷。运用AnyCasting软件模拟仿真及实际生产验证

验证了设计方案的正确性与可行性。

Abstract

The large-scale water valve belongs to a small batch production of nodular cast iron parts.Through a comprehensive analysis of its structure and production technology

sand casting was determined to produce the valve body.The core box precision assembling core was adopted to mold

and double-step ladle gating system was selected to pour with "full riser design".Meanwhile

by adding cold iron

the internal defects in the water valve body was eliminated.By using Anycasting simulation and actual production verification

the correctness and feasibility of the designed scheme were confirmed.
