The melt metering device comprises a melt reception unit movable between a melt receiving location and a melt discharge location and designed to remove a dosable quantity of casting melt material from a melt bath at the melt receiving location and then transfer and deliver to the casting device at the melt discharge location, where the melt reception unit is formed by an evacuatable dosing container (1), an evacuating device coupled with the container for evacuating the dosing container, and a controllable locking unit for selectively opening and closing a melt opening (4) of the container. The melt metering device comprises a melt reception unit movable between a melt receiving location and a melt discharge location and designed to remove a dosable quantity of casting melt material from a melt bath at the melt receiving location and then transfer and deliver to the casting device at the melt discharge location, where the melt reception unit is formed by an evacuatable dosing container (1), an evacuating device coupled with the dosing container for evacuating the dosing container, and a controllable locking unit for selectively opening and closing a melt opening (4) of the dosing container. The locking unit contains a longitudinally movable locking plugs arranged in the dosing container and the melt opening is provided in a bottom area of the dosing container. The melt opening is formed by a tubular support area projecting from the bottom area of the dosing container. The melt metering device includes a controllable protective gas impacting unit (9) for controllably impacting the dosing container with a protective gas. The dosing container has a melt bath-immersion sensor, whose sensor signal forms a control signal for the evacuating device, the protective gas impacting unit and/or locking unit, and a melt fill level sensor, whose sensor signal forms a control signal for the evacuating device, the protective gas impacting unit and/or locking unit. The evacuating device contains a vacuum pump (7) or a controllably operated piston-cylinder-unit. The melt metering device has a transfer unit, to which the dosing container is movably coupled between the melt receiving location and the melt discharge location. Independent claims are included for: (1) a method for metering melt for a casting machine; and (2) a metal die-casting machine. |
