| 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. |
