FIELD: metallurgy.
SUBSTANCE: chill mould contains at least two forming parts 1-3, forming cavities segments 7 and profitable part are performed at the surfaces of forming cavities. In a profitable part, a ceramic funnel with holes coaxial with the holes of forming cavities is installed. At the edges of the forming cavities, chamfers 9 are made, forming dross of specified shape and size, which prevents the formation of uncontrolled dross. The chill mould is made of copper or its alloys and is held by the clamping device 6.
EFFECT: increase the purity and quality of castings.
