METHOD AND DEVICE FOR UPHILL CASTING, COMPRISING A CHILL OR CORE STACKINGS WITH AN OPEN POURING GATE

摘要

The invention relates to a method for uphill casting/low-pressure casting especially light metal alloys involving a casting plate comprising a through hole; a casting furnace lying beneath the casting plate and comprising an ascending pipe which forms an upwards-opening orifice; and a casting mould comprising a base plate which has a downwards-opening pouring gate. Said orifice is joined from below to the through hole in a sealing manner; the pouring gate pertaining to the casting mould is aligned over the through hol e; molten metal is transported via the ascending pipe from the casting furnace to the casting mould, filling said casting mould; and the casting mould is displaced horizontally on the casting plate when the connection between the casting furnace and the casting mould is open and filled with molten metal, until the pouring gate is closed below by the casting plate, and the through hole is closed above by the base plate. The molten metal is then left to fal l back into the ascending pipe to a point below the orifice.
