Abstract

The low-pressure casting method for metals, comprises filling liquid metal in a form cavity (13) under pressure in a filling phase by a pump from a melt supply (1) over a pump pipe (15), solidifying the metals under balance vibration in cavity and applying low pressure on the metal by a piston in a low-pressure phase. In the melt supply a movable piston (8) is set in a holding pressure cylinder (7) connected to the pump pipe. The pump is arranged in a furnace chamber in a distance from the base and from upper melt level. The low-pressure casting method for metals, comprises filling liquid metal in a form cavity (13) under pressure in a filling phase by a pump from a melt supply (1) over a pump pipe (15), solidifying the metals under balance vibration in cavity and applying low pressure on the metal by a piston in a low-pressure phase. In the melt supply, a movable piston (8) is arranged in a holding pressure cylinder (7) connected to the pump pipe. The pump is arranged in a furnace chamber in a distance from the base and from upper melt level. A valve function is inserted within the melt supply for agitating the melt and blocks the connection between the pump pipe and the holding pressure cylinder. An independent claim is included for a device for die casting.
