INJECTION MOLDING MOLD FOR COMPOSITION FOR RESIN-BONDED MAGNET, MOLDING METHOD OF COMPOSITION FOR RESIN-BONDED MAGNET USING THE SAME AND RESIN-BONDED MAGNET OBTAINED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an injection molding mold capable of preventing breakage or chipping from occurring when the core is drawn out from the molded product after the injection molding which uses a composition for a resin-bonded magnet containing a thermosetting resin and of stably producing the thin-gauge ring-shaped product; a molding method of the composition for the resin-bonded magnet using it; and the obtained resin-bonded magnet.;SOLUTION: The injection-molding mold for the composition for the resin-bonded magnet, which is separable into the fixed side mold and the movable side mold by the parting face, is equipped with a plate that presses down the tip of the molded product obtained by curing the thermosetting resin. This leads to no occurrence of the breakage or chipping caused by the molded product being jerked with the move of the core at the time of separating into the fixed side mold and the movable side mold to remove the molded product after the injection molding, and the stable production can be attained.;COPYRIGHT: (C)2007,JPO&INPIT
