Abstract：
The surface structure of the female rotor casting was special, and the chiller cannot be placed, so it caused shrinkage defects of the casting. In order to solve this problem, the advantage of 3D printing technology of sand mold was utilized to design the heat dissipation channel in the sand core, and the compressed air was injected after pouring. The results show that there is no shrinkage porosity in the casting. Compressed air is introduced into the designed cooling channel, which can achieve the effect of chiller and solve the shrinkage porosity problem of female rotor casting.
