[0002] A vibrating sand-falling machine is a device that uses mechanical vibration and impact to separate the mold sand and castings. After searching, a vibrating sand-falling machine (publication number: CN218134911U) is now disclosed. In this patent, a vibration motor is used to provide a vibration source for the vibration bin to vibrate and screen the molding sand and the castings.
