PRESSING CHAMBER OF HORIZONTAL CASTING MACHINE UNDER PRESSURE (HCMUP) Russian patent published in 2017 - IPC B22D17/20 

FIELD: metallurgy.

SUBSTANCE: pressing chamber comprises a cylinder (1) with a filling window separated from the rear end of the pressing chamber by a web (4) and a casing (2) with an annular stop at the front end of the pressing chamber, a filling window separated from the rear end of the pressing chamber by a web, and a longitudinal through groove (5). The conjugate surfaces of the cylinder and the casing are conical. The front end of the cylinder is advanced with respect to the front end of the casing, the casing is shortened relative to the cylinder, and the filling window, made in the casing, is smaller than the cylinder filling window.

EFFECT: eliminating the cylinder misalignments in the casing and casing in the casting machine under pressure, the resistance of the sprue bushing of the mould, the cylinder and the piston moving along them without distortion are increased.
