  • Device for producing a cylinder crankcase using the low-pressure or gravity casting method
    Patent number: 9718124
    Abstract: A device for producing a cylinder crankcase using a low-pressure casting method or a gravity casting method. The device includes an outer casting mold which includes at least one mold part which, in an assembled state, forms a mold cavity that reproduces, for casting purposes, an outer contour of the cylinder crankcase. A region of the mold cavity forms a cylinder space of the cylinder crankcase. A dosing furnace contains a liquid metal. At least one gate is arranged geodetically below the mold cavity and via which the dosing furnace can be fluidically connected to the mold cavity. Sprue bushings project into the region of the mold cavity that forms the cylinder space of the cylinder crankcase. Each of the at least one gate is connected to one of the sprue bushings.
