Method and apparatus for cleaning passageways in metal castings
Metals castings, having a number of internal passageways which open at different surface portions of the castings, are mounted upon a horizontally axised wheel-like frame. The frame is intermittently rotated and momentarily stopped so that castings are rotated at times and stationary at times. Durin...

| description | Metals castings, having a number of internal passageways which open at different surface portions of the castings, are mounted upon a horizontally axised wheel-like frame. The frame is intermittently rotated and momentarily stopped so that castings are rotated at times and stationary at times. During the times that the castings are stationary, they are simultaneously subjected to either an externally applied vibration or to a momentary, several millisecond long, high pressure burst of air through their respective passageways. The alternating vibrations and momentary bursts of air loosen and remove the sand and other casting debris contained within the passageways. Additionally, the changing angularity of the castings, due to the rotation, coupled with the vibrations and bursts of air, dislodge such sand and debris from the walls and, also, downwardly out of the passageways. |
