A mould structure for producing metal castings by solidifying molten metal, in particular for producing a light-alloy engine crank-case, which includes a plurality of cores (4-17) defining a mould cavity (18) and a primary inlet aperture (42) for feeding the molten metal into the bottom region of the mould cavity (18) through the walls of one of the said cores, which includes: a metal containment structure (1), open at the top, with a bottom wall (2) and side walls (3) having a plurality of reference elements (19-26) which have surface portions which complement surface portions of the said cores, the said cores being assembled inside the containment structure so that they are engaged with each other and with the said reference elements, and being shaped so as to define interstices (27-32) between their surfaces facing outwardly of the mould cavity and the walls of the containment structure; and at least one cover element (38) made of a highly heat-conductive material, supported by the side walls (3) of the containment structure and by some of the said cores (11, 12) and serving to close the top of the mould cavity.
