Abstract
A device for manufacturing an engine block has a casting mold with mold parts and cylinder liners. The mold parts have a seat with seat surfaces for each cylinder liner, and the opposed ends of the cylinder liner are seated in the seat surfaces. The cylinder liners become connected to the material cast in the casting mold and are removed together with the cast material from the mold parts after casting. The seat surfaces are conical and inclined at an incline angle relative to the cross-sectional plane of the cylinder liner seated in the seat such that the opposed ends of the cylinder liner remain seated at the seat surfaces upon heat expansion of the cylinder liner during preparation of the casting mold for casting and during casting.
