摘　　要：用没有粘结剂的干砂造型是消失模铸造的特点之一，而干砂的充填和紧实的质量直接影响铸件的质量，因此性能良好的造型振动台是消失模铸造的关键设备。介绍了自行设计和制造的单片微型机控制的三维振实台的结构和特点；ＭＣ－５１单片微型机硬件和控制软件的特点。通过生产验证表明，该机能根据不同铸件的形状、结构，实施不同的干砂充填紧实工艺，保证消失模各个部位能稳定获得足够的充填和紧实，铸件质量良好。Dry sand molding without binder is one of the main characteristics of the expendable pattern casting, and the casting quality is directly connected with the filling and compacting quality. Therefore, the vibration table with excellent filling and compacting properties is the dey equipment for EPC. This paper introduces the structure and characteristics of the self\|designed microcomputer controlling 3D vibration compacting table and the characterisics of MC\|51 microcomputer hardware and controlling software. Through practical use, it is shown that the machine can carry out different filling and compacting processes according to the shapes and structures of different catings and guarantee efficient filling and enough compactibitlity at individual position, with good castings quaiity.\=
