Production of cylinder block in a composite mold used in the manufacture of liquid cooled internal combustion engine with avoidance of large weight deviations in pressing the cylinder jacket wall under the casting pressure

摘要

Production of a cylinder block in a composite mold for a liquid cooled internal combustion engine, in which several in series one piece cylinder tubes (2) in Al alloy as a closed insert (3) in a mold formed in a cylinder block jacket (4) are cast with an Mg alloy, where a coolant space (5) is provided, and the cylinder jacket wall (6) is heated to a predetermined temperature in an iron mold, with pressure forming until the Mg alloy is cooled.
