Abstract
A casting device for counter gravity casting of a light-metal alloy avoids local expansion of the mould cavity. The device includes a pump for conveying molten light metal from a holding furnace through a reservoir via a nozzle to an inlet system in a mould in order fill the mould cavity. The mean cross-sectional area of the reservoir is substantially greater than the mean cross-sectional area of the inlet in the mould. The length of the reservoir constitutes a major portion of the distance between the pump and the mold.
Claims5
A casting device for counter-gravity casting with a light-metal alloy through a bottom inlet of a mould, said device comprising a holding furnace for containing the molten light-metal alloy, a pump for pumping the molten light-metal alloy from the holding furnace into said mould, and a conduit between the furnace and the bottom inlet of the mould, said conduit comprising a reservoir extending over a majority of the length of said conduit having a mean cross-sectional area of 30 to 70 times the mean cross-sectional area of the bottom inlet of the mould.
