METHOD FOR MANUFACTURING FRICTION PLATE, AND APPARATUS FOR CASTING CORE PLATE IN FRICTION PLATE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a friction plate by which the side surface of a core plate can smoothly be formed while restraining the development of warping at the casting time of the core plate and a lining can accurately be stuck on the side surface without applying machining-work and a trimming is scarcely needed. SOLUTION: In the method for manufacturing the friction plate composed of the core plate 15 integrally projecting a plurality of transmission claws 15b on the inner periphery or the outer periphery of an annular core plate body 15a and the lining 16 stuck on the side surface of the core plate body 15a: this method is contained of; a casting process for forming the core plate 15 by casting raw material into a cavity 26 demarcated between a fixed metallic mold 25 and a movable metallic mold 27 corresponding to the outer shape of the core plate 15; a mold opening process for opening between both metallic molds 25, 27; a discharging process for discharging the core plate 15 by rotatively shifting a part 30 in contact with the whole body at the one side surface of the core plate 15 in the one side of the metallic mold to the other portions 28, 29; and a lining sticking process for sticking the lining 16 on the side surface of the core plate body 15a of the core plate 15.
