MOLD FOR MOLDING MAGNET ROLL

摘要

PROBLEM TO BE SOLVED: To always hold the position of a roll main body part with respect to a shaft part to a predetermined position while avoiding that a mold becomes inadvantageous from an aspect of cost and an apparatus is scaled up. SOLUTION: A mold for molding a magnet roll is equipped with a main mold 14 for forming a molding space filled with a molten magnet material and the slide mold 20 arranged in the molding space of the main mold 14 in a freely accessible manner and moved to a retreat side accompanied by the filling of the molding space with the molten magnet material to form the shaft part of one end of the magnet roll. Rotation stopping parts 14A, 14A for preventing the rotation of the slide mold 20 at a time of the advance and retreat of the slide mold 20 are formed to the main mold 14 along the respective longitudinal directions thereof and the guide parts 20A, 20A movable along the rotation stopping parts 14A, 14A are formed to the slide mold 20 to form the mold for molding the magnet roll.
