摘要

1. A core for the blow-moulding of an internal lining of a container for molten metal, characterized in that it comprises a main body (3), equipped with blowing holes (6a, 6b) and an escape orifice (7), the peripheral face and the lower face of this body having the same dimensions and the same shape as the corresponding internal faces of the lining to be moulded, a flange (9) which, starting from the periphery of the upper extremity of the body (3), extends outwards approximately horizontally, a plurality of supports (4) which are actuated towards the base of the flange, and airtight joints forming shock-absorbers (5) placed below the flange.
