Abstract
Abstract
In this paper, a complex aluminum alloy lube oil pump casting with many interconnected oil pipes was produced by sand mould-type, low-pressure casting (LPC). The sand mould was designed as a monolithic structure and produced by selective laser sintering (SLS) technology. The impact of pouring pressure on casting defects was studied by the casting simulation software PROCAST. The optimal lifting pressure velocity was 0.65KPa/s and the filling pressure velocity was between 2.4KPa/s and 4.8KPa/s. Adopting optimal pouring pressure conditions, the casting with defect-free and high dimensional accuracy was successfully produced.
