Injection mold for motor wind wheel

The invention discloses an injection mold for a motor wind wheel. The injection mold comprises an outer box, a box cover and an injection molding port, wherein the injection molding port is connectedwith an injection molding cavity in a sealing mode, a mold cavity is formed in the outer box, a mold cavity sleeve is connected to the outer side of the mold cavity in a sealing mode, the outer box isprovided with a cooling cavity located at the outer side of the mold cavity sleeve, a cooling sleeve is connected to the outer side of the cooling cavity in a sealing mode, magnetizing liquid is contained in the cooling sleeve, a permanent magnet is fixedly connected to the outer portion of the bottom of the cooling sleeve, and the mold cavity sleeve and the cooling sleeve are jointly connected with a transmission structure. The injection mold has the advantages that according to a magnetothermal effect, an injection molding product is cooled through the demagnetization heat absorption actionof a ferromagnetic substan
