摘要： The present invention relates to a casting mould for casting a casting, in particular an engine block for a combustion engine, as well as to the use of such a casting mould, comprising mould parts 1, 2, 3 and casting cores 4, 5, 6, 7 produced from moulding sand, and at least one casting core 4, 5, 6, 7 for the formation of a space in the casting. The casting mould according to the invention makes it possible, in a simple manner, for castings to be produced in which at least one locally closely confined section is formed with a microstructure which differs from the remainder of the casting. This is achieved in that a section of the casting core 4, 5, 6, 7 is formed by a chill 9 which is manufactured from a material of which the thermal conductivity is many times higher than the thermal conductivity of the other section 8 of the casting core 4, 5, 6, 7, consisting of moulding sand.
