Abstract

A casting die for the production of a cylinder block/crankcase of an internal combustion engine includes at least one sleeve, which may be moved relative to its axis and is fitted in each case with a cylinder liner, the sleeve keeping open the cylinder bore of the cylinder block/crankcase and extending from a wall on the cylinder-head side of the die to a wall on the crankshaft side of the casting die. The cylinder liner ends at least 3 mm before the wall on the cylinder-head side of the casting die, and the cylinder liner is held at a distance from the wall on the cylinder-head side of the casting die by a spacer.
