摘要:某型高功率密度柴油机采用无管化、免维护设计的零件集成了大量水腔与油腔,其结构复杂,零件铸造难度高。为优化铸造工艺,在零件生产阶段采用3D打印砂芯的方式,结合铸造仿真技术和熔炼控制技术,快速进行多轮铸造工艺优化验证,有效降低了铸造难度并提高了铸造精度。该方法在柴油机研制阶段缩短了复杂零件的制造周期和开发成本。

Abstract:The component of a high power density diesel engine was designed with no pipe and maintenance-free, and inside it integrated lots of water and oil cavities, thus had a complex structure and hard to cast. To optimize the casting technology, the technology combing 3D printing sand cores with casting simulation and smelting control were employed in the production of the component. Several rounds of verification about the casting optimization scheme were carried out in very short time, which made the casting easier than before and boasts high precision. This technology can cut the manufacturing cycle and development cost of complex components in the stage of engine design.
