Giessform und Giessverfahren zur Herstellung eines Motorblocks

摘要

The engine block has structured cooling channels in the walls between the cylinders with a reduced cross section where the channel axis intersects the cylinder axes. The cast engine block has a cooling channel in the intermediate cylinder wall with a minimum cast wall thickness of less than or equal to 5 mm. The cooling channel is wholly defined by a skin of the cast material. The cross section surface of the cooling channel is reduced from its end to a cross section surface of the cooling channel axis (14) where it intersects the cylinder axis. The minimum width of the cooling channel at the cross section surface axis at the intersection with the cylinder axis is 0.5-1.5 mm. The mold has channel molding cores (8) at the ends of the cores (2,3) to give the cylinder openings.
