柴油机气缸体消失模铸造工艺的优化设计

摘要

从泡沫模样的制作、型砂的选用、造型工艺以及浇注系统的设计诸方面阐述了直列四缸柴油发动机气缸体消失模工艺的优化设计.%Based upon traditional diesel engine cylinder block casting process, four-cylinder diesel engine cylinder block lost foam process design and optimization of application have been described as: to assemble product pattern and pouring system model formed with expandable polystyrene beads into a model cluster, then dry them after the model cluster dipping with the aid of manual or manipulator before put them into single sand box which with a negative pressure pumping system, a single dry sand rain-type sand system filling and compaction. Finally, to achieve the solidification of molten metal casting and forming under a certain vacuum.
