Abstract
A casting 31 is fixed to a support member 23, and the casting 31 is hit by a hammer 43 while vibrating the support member, so that vibrations of different properties are applied to the casting to shake out the sand.
Claims12
A casting sand shake-out method characterized by fixing a casting to a support member, indirectly connecting a hammer to the support member, and hitting the casting by the hammer while vibrating the support member;
- wherein the vibration applied to the support member has a conveying performance in one direction, and sand sticking to the inside and outside of the casting is separated by this vibration away from the casting fixed to the support member and the sand is discharged, and an impulsive vibration is also given to the casting by the hammer to promote said separating action, thereby sending out the sand falling on the support member in one direction.
A casting sand shake-out apparatus comprising:
- a support member to which a casting is fixed;
- means for vibrating the support member;
- and a hammer for hitting the casting, wherein the hammer is indirectly connected to the support member, and wherein sand sticking to the inside and outside of the casting is separated away from the casting fixed to the support member and discharged by the vibrating means, and an impulsive vibration is applied to the casting by the hammer, thereby promoting said separating action;
- wherein the vibration of the vibrating means has a conveying performance in one direction such that sand separated from the casting is conveyed by vibration and sent outside of the apparatus.
