On the basis of the design theory and production experiences about the running and feeding system, the authors have compiled the CAD software for such a system of the nodular iron casting. 根据浇冒口设计理论及生产经验,编制了球铁件浇冒口系统的计算机辅助设计软件。
Foam mould is used with Tri-box quartz sand air set molding and the quality of pallet is ensured by reasonable design of running and feeding system and placing internal chill in the middle wall-thick position. 通过对托盘结构的分析,设计合理的浇冒系统,采取在中间壁厚部位安放内冷铁等措施,保证了托盘的质量。
