Patent number: 7784526Abstract: A sand-introducing device that uses air for introducing molding sand in a molding space or spaces is provided. The device is provided with air-permeable partitioning plates that define a double-walled structure together with the wall of the body of the device. The air-permeable partitioning plates are easily produced, they can easily inject pressurized air of a desired pressure, and they will not need regular maintenance. The body of the device, which acts as a pressure tank, defines a double-walled structure together with the air-permeable partitioning plates (10, 11), thereby defining chambers (12, 13). In the sand-introducing device that uses air, while molding sand is fluidized by pressurized air injected from the air-permeable partitioning plates, it is introduced in a molding space. Each air-permeable partitioning plate is made of a porous resin or metal.Type: GrantFiled: October 13, 2009Date of Patent: August 31, 2010Assignee: Sintokogio, Ltd.Inventors: Hisashi Harada, Takuya Nitta, Takashi Hanai, Minoru Hirata, Kozo Sugita, Toshihiko Oya
