针对EIZ80机壳铸造工艺特点,采用组芯造型、抽芯式模型结构,运用均衡凝固理论设计浇注系统。采用分散3层阶梯式浇注系统,用陶管分别从铸件的底层、中间和最上层引入等工艺措施,成功浇注出铸件内在质量好,表面光洁,加工过程中无铸造缺陷的EIZ80机壳铸件,实现了国产化铸造。 According to the casting process characteristics of EIZ80 chassis, the core structure and core-pulling model structure are adopted, and the pouring system is designed by the theory of equilibrium solidification. Dispersed three-tier cascade casting system, the use of ceramic tubes were introduced from the bottom, middle and top of the castings and other process measures, the successful casting of the casting internal quality, smooth surface, no casting defects in the process of casting EIZ80 chassis castings, Achieved localization of casting.
