Method for the production of a metal casting with at least one hole and a die for its production

摘要

To form elongate holes in the casting, metal inserts, e.g. tubes and/or bushes, are held in an empty die by means of a holding device (9) or by means of retractable holding members (18, 19, 26) and a molten metal is poured around them. The metal insert (8, 13, 17, 23) remains in the casting. <IMAGE>
