Manufacturing method of mold mold for motor stator and mold mold for motor stator

摘要

Problem to be solved with respect to a motor stator comprising a core formed by laminating a plurality of annular electromagnetic steel plates and Coyle wound around a plurality of slots formed at predetermined intervals on the inner periphery of the core The mold mold 1 used at the time of molding molding in which the insulating resin is injected into the space between at least the core and the Coyle to cure the molding can be sufficiently tolerated for repeated use.Solution: the mold 1 comprises a long trunk portion 11 and a collar portion 12 extending outwardly from one end in the longitudinal direction of the body portion 11, and the outer peripheral surface 11a of the body portion 11 of the mold mold 1 is shot peeled and then electroless plated.Diagram
