Aluminum rim casting mold

The invention discloses an aluminum rim casting mold which comprises a main mold body, wherein a cooling channel structure is arranged inside a high-temperature heated position of the main mold body; the inlet of the cooling channel structure is connected with a water-gas mixing device for supplying water mist; and the outlet of the cooling channel structure is connected with a recovering circulation device. In the invention, the cooling channel structure is arranged inside the high-temperature heated position of the casting mold and is connected with the water-gas mixing device for supplying the water mist, so that heat is taken away by the circulation of the water mist in the cooling channel structure, the cooling effect is good, the normal service life of the mold is not influenced, the high-temperature heated position can be effectively and partially cooled, a position needing to be cooled is cooled accurately at a fixed point, the production efficiency and stability are high, the water ...
