Publication number: 20100065241Abstract: A device for removing sand from a work by vibration which vibrates a molding (work) molded by casting such as an auto part to thereby remove core sand remaining on a hollow portion of the work and in which the work is held against a vibration plate and the vibration plate is vibrated with a single vibration motor to remove the sand. The device for removing sand from a work 1 by vibration which removes sand remaining on the work 1 by vibration, the device comprising a base 3, a vibration plate 5 mounted on the base 3 via elastic support members 4, a work holder 6 provided on the vibration plate 5, and a vibration motor 7 connected to the vibration plate; wherein the work is held with the holder 6, and the vibration motor 7 is then actuated to vibrate the vibration plate 5, thereby applying vibration to the work 1 held with the holder 6 to remove the sand from the work 1.Type: ApplicationFiled: March 22, 2007Publication date: March 18, 2010Applicant: Shiga Yamashita Co., Ltd.Inventor: Kaoru Ichihashi

Publication number: 20040132394Abstract: An apparatus A for cutting off an unnecessary object deposited on a casting includes a motor having a rotary shaft 3 adapted to be rotated at a high speed, and a disk-shaped diamond tip saw 2 mounted at a tip end 4 of the rotary shaft 3 and adapted to be rotated by the rotation of the rotary shaft 3 to cut off the unnecessary object 9 on the casting 8, so that the tip saw 2 is rotated at a rotational speed in a range of 6,000 rpm to 8,000 rpm. Thus, the rigidity of the diamond tip saw 2 rotated at the high speed is increased by a centrifugal force provided by the diamond tip saw 2 itself and a gyroscopic moment effect to reduce the thickness of the diamond tip saw 2 can be reduced by a value corresponding to an increment in rigidity of the tip saw 2, whereby the amount of diamond tips (diamond blades) used can be decreased; an energy-saving for a cutting power can be achieved, and the amount of chips produced upon the cutting of the unnecessary object can be reduced.Type: ApplicationFiled: December 18, 2003Publication date: July 8, 2004Applicant: Shiga Yamashita Co., Ltd.Inventor: Takao Harikawa
