Abstract
An acoustically enclosed apparatus for shaking out sand-cores from metal castings. A plurality of percussive shakeout stations are spaced around the circumference of a turntable. The stations are separated one from the other and from their surroundings by an acoustical enclosure which rotates with the turntable and within a stationary enclosure. The castings are loaded and unloaded through outwardly facing access openings in the rotatable enclosure as they become registered with an access port in the stationary enclosure. Shaking out is effected while the access openings are out of registry with the access port. The sand collector beneath the stations attenuates the sound emitted from beneath the station.
