METHOD FOR MANUFATURING AIR-COOLED HOUSING MODULE OF MOTOR

摘要

The present invention relates to a method for manufacturing an air-cooled housing module for a motor capable of being easily operated and manufactured and improving heat radiation efficiency. The method includes a step of attaching a molding material leakage prevention unit to the outer wall of a heat radiation part (114) to prevent the leakage of a molding material from the inside of the heat radiation part (114) having a foaming agent in a mold process to the outer wall of the heat radiation part (114); a step of arranging the heat radiation part (114) having the molding material leakage prevention unit in a mold frame; a step of arranging a core in the heat radiation part (114); a step of injecting a molding material between the core and the heat radiation part (114); a step of separating a housing (112) formed by hardening the molding material and the heat radiation part (114) from the mold frame; and a step of removing the molding material leakage prevention unit attached to the outer wall of the heat radiation part (114).
