Abstract
This paper describes the traditional diesel engine cylinder block casting process on the basis, focusing on inline four-cylinder diesel engine cylinder block lost foam process design and optimization of application. Product pattern and pouring system model formed with expandable polystyrene beads, and assemble them into a model cluster, man can drying them after the model cluster dipping with the aid of manual or manipulator . Put the drying model cluster into the 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.
