Abstract
An apparatus is disclosed for removing molding sand from a cast part. The apparatus includes an open framework vibratory mechanism for causing movement of the molded parts through a tunnel-like member. This movement shakes and jolts the parts to loosen sand and free it from the casting. Also provided are particulate blasting means located at strategic positions in the tunnel enhancing removal of the mold sand.
Claims5
A device for removing mold sand from castings comprising:
- a. an open framework vibratory conveyor receiving said castings and subjecting them to a jolting action to loosen and break up said sand;
- b. a blast enclosure disposed about at least a portion of said conveyor;
- and
- c. blasting means mounted to said enclosure for throwing particulate at said castings through said open framework to enhance and accelerate the breakup and removal of sand by said vibratory conveyor,
- said open framework conveyor including a plurality of spaced bars which support and guide said casting, and wherein the configuration of said bars changes to alter the spatial orientation of the castings thereby to subject a greater portion of the castings to the blast means.
