Metallic mould for the production of large cast iron parts made of metal alloys

摘要

Metallic mould (d) with a running system (l) to the design of both the outer, as well as the inner shape of a large casting part (6) made of metal alloys, which consists of a plurality of shape elements (1.1, 1.2, 2.1, 2.2; 3.1 to 3.8) in the parting planes on joining edges (4) is joined together, the removal from the mould of the large casting part (6) after the solidification of the cast material as well as a re-use of the shaped elements make it possible, characterized in that, in the parting planes at the joining edges (4) between the shaped elements expansion gaps and provided with a temperature - and dimensionally stable, the pressure of the thermal expansion of the shaped elements after filling of the hot melt yielding sealing material are filled.
