PROJECTION MOLDING DIE ARRANGEMENT AND METHOD OF MANUFACTURING OF MAGNET-EMBEDDED ROTATOR

摘要

PROBLEM TO BE SOLVED: To provide a magnet-embedded rotor capable of completely fixing a permanent magnet with preferable balance, preventing breakage of a laminated iron core even if molding pressure of resin is applied to the laminated iron core while filling in a resin material, and improving reliability.;SOLUTION: In this device for manufacturing the magnet-embedded rotor, the permanent magnet 6 is fitted in a plurality of holes of the laminated iron core 3 formed by laminating plate-type magnet members, and the rein material 8 is filled through a filler hole. A slide member 11c is provided which is brought into partial or total contact with an outer-periphery of the laminated iron core 3, and the resin material is filled in between the hole and the permanent magnet with the slide member 11c gripped and fixed by an upper die 10 and a lower die 11.;COPYRIGHT: (C)2008,JPO&INPIT
