Abstract
A cylindrical element (14) with a through-going passage (15) is retained in the mold in such a manner that a part of the element (14) protrudes from the outside of the mold, and so that the passage (15) opens into a part of the runner (8) of the mold, the internal terminal surface of element (14) lying opposite a plane surface (16) in the runner (8). During casting, the nozzle (13) of a casting device is brought into tight-fitting abutment against the outer end of the element, and the molten metal alloy is cast into the mold through the nozzle (13), the passage (15) in the element (14) and the runner (8) of the mold. After casting of the mold, the nozzle (13) is pressed against the element (14) with a considerably greater force than its abutting force during casting, thus causing the element to be displaced axially into the mold to form a fight-fitting abutment against the surface (16) in the runner (8) and blocking the latter, enabling the nozzle (13) to be withdrawn without cast metal flowing out from the mold.
