Patent number: 8268219Abstract: A laminated rotor core (36) wherein permanent magnets (47) are inserted in respective magnet insertion holes (46) is disposed between and pressed by an upper die (37) and a lower die (29). The upper die (37) has resin reservoir pots (50) provided above the laminated rotor core (36) and at positions corresponding to the respective magnet insertion holes (46). Raw resin material put in the resin reservoir pots (50) is heated by the upper die (37). Subsequently, the resin material in a liquefied state is ejected from the resin reservoir pots (50) by plungers (52) that are inserted and moves vertically in the resin reservoir pots (50) and is directly filled in the magnet insertion holes (46). Consequently, the respective magnet insertion holes (46) are filled with the resin material more evenly and highly reliable products can be supplied at low cost.Type: GrantFiled: January 24, 2011Date of Patent: September 18, 2012Assignee: Mitsui High-Tec, Inc.Inventors: Satoshi Matsubayashi, Hirotoshi Mabu, Katsumi Amano, Atsushi Shiraishi

Publication number: 20020129677Abstract: A stamping punch of a punching apparatus including a grip member provided with crosspieces formed between long grooves on side walls of a rectangular parallelepiped, and a plurality of punch members which are formed integrally with the grip member. The respective punch members are arranged in parallel to one another. A plurality of holes are defined on a punch holder. A large amount of adhesive is contained in the gap between joining surfaces when the grip members of the stamping punches are inserted and secured into the respective holes. Accordingly, the positional accuracy of the punch member is improved, the accuracy of the hole defined through a workpiece is improved, and it is possible to eliminate any fear of occurrence of defect in shape. Further, the rigidity of the punch member can be improved, the stripper is prevented from application of unbalanced load, and the punch is easily exchangeable.Type: ApplicationFiled: May 10, 2002Publication date: September 19, 2002Applicant: NGK Insulators, Ltd.Inventors: Hiroyuki Tsuji, Kazumasa Kitamura, Motoo Noritake, Satoshi Matsubayashi, Shusaku Kabe
