    Abstract: The application belongs to the technical field of a casting mold and provides a side mold and a low-pressure hub casting mold. Channels of a cooling loop are processed in a back cavity of a side mold frame, a distance between the channels along a solidification direction of a casting gradually increases, and a cooling medium flows along the cooling loop, the ability of taking away heat changes from strong to weak, and a larger temperature gradient of the side mold may be formed by superposition with a temperature gradient formed by the thickness of the side mold.
