Patent number: 11590683Abstract: A molding-forming method, a molding mold, and a molding production apparatus with which efficient burrs removal is possible without requiring a large apparatus. A molding production method includes, in addition to a molding being formed inside a mold, burrs formed around the molding are separated from the molding. After formation of the molding, air is blown inside the mold on at least a portion of the burrs formed around the molding to cool the same, a projecting member is projected toward the cooled burrs, and the burrs are separated from the molding. After pressing the burrs toward the projecting member by the air blowing, the burr is pressed toward the mold surface facing the projecting member by projection of the projecting member to separate the burr from the molding.Type: GrantFiled: October 30, 2018Date of Patent: February 28, 2023Assignee: KYORAKU CO., LTD.Inventors: Kengo Shimada, Tadatoshi Tanji, Naoto Tani, Masaaki Onodera
