Design Optimization of Diesel Engine Cylinder Block Casting Process

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.
