Abstract

A casting mould for bottom pouring from a sealed chamber (10) with molten metal under the action of a gas pressure difference. The mould comprises respective mould parts (1, 2) forming a casting cavity (3) and a gating system for the supply of molten metal. The gating system comprises a gas-tight runner (4, 41) connected with the mould cavity (3) via an overflow-feed conduit (6) which is gas-permeable during the filling of the mould cavity and becomes gas-tight after the filling. In the overflow-feed conduit there is formed a lining (8) comprising an insert (7) which is provided with through-holes (71). There is a sealing surface (5) by which the casting mould is connected via a seal (12) to a movable feed tube (11), disposed in the sealed chamber (10) with molten metal. <IMAGE>
