The flow field and solidification of aluminum alloy caliper under gravity and tilting pouring condition were analyzed by numerical simulation.And the change curve of the specified temperature under the color temperature of the casting temperature changes was observed during the solidification process for the selected temperature-measured points.Compared with gravity casting

the tilting casting process exhibits more stable with the lower temperature gradient

so the gas is easy to be exhausted

which takes the absence of shrinkage

porosity and shrinkage defects.Adopting tilting casting design with three parts in one mould

the experimental results indicate that the product quality presents desirable

and the caliper quality and the production yield are improved greatly.
