  • Mould structure for producing light metal alloy casts and a low pressure precision casting method in a semi permanent mould
    Patent number: 6516869
    Abstract: 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 defining a mould cavity and a primary inlet aperture for feeding the molten metal into the bottom region of the mould cavity through the walls of one of the said cores, which includes: a metal containment structure, open at the top, with a bottom wall and side walls having a plurality of reference elements 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 between their surfaces facing outwardly of the mould cavity and the walls of the containment structure; and at least one cover element made of a highly heat-conductive material, supported by the side walls of the containment structure and by some of the said cores and servi
