Mold for manufacturing motor hubs

The invention provides a mold for manufacturing motor hubs. The mold comprises an upper model, an upper mold and movable blocks; lifting lugs are arranged at two ends of the upper surface of the uppermodel, and a support ring is arranged on the inner side; the upper mold is a molding cavity integrally molded, and comprises an upper cavity and a lower cavity; multiple movable blocks are arc blocks, projection blocks are arranged above the inner sides, and holes are formed in two sides; magnets are mounted in the holes; and the multiple movable blocks are assembled as a ring, and can be disposed in a manner of fitting the upper cavity of the upper mold. The upper mold is the molding cavity integrally molded to solve the inclined cutting problem of sand cores; and meanwhile, through arrangement of the movable blocks, the problem of incapability of retreating from the mold cavity due to the avoiding angles of a hub mold in traditional mold production is solved, so that operators can quickly produce higher-quality
