Abstract

The use of cooled metal rod(s) is claimed as core for the production of the cylinder cavity in a cylinder crankcase, cast from a light metal alloy in a sand mold and having at least one cylinder, for producing a very low porosity cylinder bearing surface suitable for application of an abrasion-resistant coating. Independent claims are included for: (1) a plant for casting a cylinder crankcase of light metal alloy in a sand mold formed as a core package (6) with: a casting plate (7), on which the core packet is positioned using cams (10); a receiving frame lowerable by a cylinder (1) and positioned using centering pieces (11, 12) and casting plate height adjusters (16, 17); and cooled metal rod(s) (5), positioned on the receiving frame in a guide (4) and insertable into opening(s) in the sand mold, as core for producing the cylinder cavity; (2) a corresponding cylinder crankcase production method, including the insertion of the metal rod(s) as core for producing the cylinder cavity, where the rods cause targeted, intensive abstraction of heat from the melt, directed pore-free solidification in the cylinder bearing surface region and good penetration through the whole wall thickness.
