Research on Low Pressure Casting Technology of Aluminum Alloy Oil Pan
Aluminum alloy oil pan is a thin-walled casting with complex internal oil channel structure.This article analyzes and studies the low-pressure casting process and typical casting defects of oil pan products from the aspects of casting structural characteris-tics,casting hot spots,gating system,mold exhaust,etc.By adding process grids to improve the fluidity and exhaust capacity of aluminum liquid,setting exhaust ducts at large plane positions to increase exhaust capacity,and optimizing product wall thickness to ensure inde-pendent hot spot feeding effect,the Al oil pan can be produced by low-pressure casting.
