ABSTRACT:
Sand bales containing castings are removed from poured foundry molds by clamping together in a horizontal position the molding boxes containing the sand bales, by supporting the sand bales from below independently of the molding boxes, and by applying to the molding boxes jarring or accelerative forces acting in a vertical direction with a magnitude exceeding the static frictional forces which exist between the sand bales and the molding boxes, with these forces being applied while the sand bales are supported thereby to cause the sand bales to move out of the molding boxes. In one aspect, the sand bales are supported from below by a force lower than the weight of the bales thereby to permit the bales to drop out of the molding boxes while the accelerative forces are applied to the molding boxes in an upward direction. Conversely, the sand bales may be lifted upwardly out of the molding boxes with accelerative forces being applied to the molding boxes in a downward direction.
