The invention relates to a device for removing at least one cooling element from an at least partially demoulded cast part, in particular from a cast housing for an electric motor formed from a light metal alloy, which has an apparatus for removing the at least one cooling element. Furthermore, the invention relates to a method for removing at least one cooling element from an at least partially demoulded cast part, a method for introducing at least one cooling element into a mould core of a cast part mould, a cooling element, and a cast part.

The present invention relates to a foundry core, which has the base form of a hollow body, with the foundry core being formed from a moulding material consisting of a mixture which is formed from a moulding sand and a binder and optionally from additives added to set its properties and a method for its manufacture. The foundry core according to the invention can be easily manufactured. This is achieved as a result of the foundry core being divided into at least two sub-segments and forming elements interacting with one another in a positive-locking manner being provided on the edge sides, with which sub-segments arranged adjacent to one another abut on one another, or in proximity to these edge sides, via which forming elements the sub-segments arranged adjacent to one another are fixed by positive locking immovably against one another at least in one direction.

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.
