A three part mould for an engine cylinder block which has several aligned cylinders with parallel axes, several bearings for mounting a crankshaft having an axis perpendicular to the cylinder axes, voids formed around the cylinders, and recesses between the bearings and the cylinders, includes an upper segment, a lower segment and a central segment. The three segments are superposed in the direction of the cylinder axes. The upper segment forms the cylinders and at least one portion of the voids. The lower segment forms the bearings and at least one part of the recesses. The central segment forms matching parts of the voids and the recesses.
