<p>The method comprises joining a cope (19) and drag (20) to form a mold flask (15) having a horizontal parting plane (21) which passes through a pouring cavity (39) in the flask, tilting the flask so that the parting plane is vertical and the pouring cavity is at the vertically upper end of the flask and, while the flask is vertical, pouring molten metal through the cavity to fill the flask mold. Each filled flask is maintained in the vertical orientation until the molten metal cools. After the metal cools, the flask is tilted until the parting plane is horizontal, before the cope is detached from the drag and the cast part removed. Preferably, at least two flasks are arranged on a single pallet with their parting planes oriented vertically. The preferred drag has a drag outer flange (29) and a parting line flange (37), and the cope has an outer flange (23) and a cope parting line flange (27). The parting line on the drag and the parting line on the cope include respective notches (38, 28) for defining the pouring cavity.</p> |
