Device for removing sand by vibration

Abstract

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.

1 . In a device for removing sand or core sand from moldings or in a hollow portion of the moldings by vibration which removes sand remaining on the molding said device for removing sand by vibration comprising
 base,   a vibration plate mounted on the base made of elastic support members,   a molding holder provided on the vibration plate, and   a vibration motor directly connected to the vibration plate,   wherein the molding which is to have sand to be removed is held with the holder,   characterized in that: the vibration motor is a single vibration motor and is actuated to vibrate the vibration plate, thereby applying vibration to the molding held with the holder to remove the sand from the molding.   
     
     
         2 . The device for removing sand by vibration according to  claim 1 , wherein solid grains are placed in the hollow portion of the molding to facilitate the removal of the core sand in the hollow portion.
