Abstract
A method of casting is provided which uses boxless moulds. The method comprises the steps of stacking a plurality of boxless moulds substantially horizontally on one another in a frame to form a substantially vertical stack, pivoting the frame with the moulds therein through an angle of approximately 90.degree. so that each mould stands substantially vertically, and filling the moulds with molten metal while they are in the substantially vertical position.
Claims6
A method of casting utilizing boxless molds, the method comprising the steps of:
- (1) conveying molds at a first level to a frame maintained in a vertical position, the frame comprising a lower support surface for molds and a rear abutting plate, the lower support surface being initially substantially at the first level;
- (2) stacking a plurality of boxless molds one on another in the frame to form a substantially vertical stack, each mold being in a substantially horizontal position and abutting against the rear plate;
- (3) lowering the frame into a pit therebeneath during stacking of the molds on the frame, so as to maintain the top surface of the uppermost mold substantially at the first level;
- (4) lifting said frame from said pit and securing the molds within the frame, then pivoting the frame with the molds therein to an angle of approximately 90.degree. so that each mold stands substantially vertically, the molds resting upon the abutting plate;
- and
- (5) filling the molds with molten metal while maintaining the molds in the substantially vertical position.
