Riser sleeves for metal casting moulds |
摘要 |
A riser sleeve has at its end which is uppermost when the sleeve is located in the mould a holding member which can be engaged by a mechanical holding device so as to adapt the sleeve to automatic handling. The holding member may be for example a disc, ring or solid or hollow cylinder and may be formed integrally with the sleeve or formed separately and fixed to the sleeve. By adopting a standard shape and size for the holding member for a wide range of sleeve shapes and sizes the same holding device can be used to handle the whole range of sleeves.
