Abstract
A casting mould is disclosed for manufacturing a casting from a metal melt (S) in a hollow moulding cavity (5) for reproducing a casting, and through an inlet for pouring a metal melt (M) into the hollow moulding cavity (5), as well as a device and a process for casting such metal melts. The disclosed casting mould also makes it possible to achieve a further optimised casting result, even in the hard operation conditions found in casting practice.
Moreover, the use of the claimed device and process minimises the risk of jamming because of a pressure build-up during casting. This is achieved in that the casting mould comprises at least one compensation chamber (8, 9) linked to the moulding cavity (5) by a channel (10, 11) and having at least one section (8a, 9a) located above the maximum filling level (Fmax) of the casting mould (1) during the solidification of the metal melt (S).
Moreover, the use of the claimed device and process minimises the risk of jamming because of a pressure build-up during casting. This is achieved in that the casting mould comprises at least one compensation chamber (8, 9) linked to the moulding cavity (5) by a channel (10, 11) and having at least one section (8a, 9a) located above the maximum filling level (Fmax) of the casting mould (1) during the solidification of the metal melt (S).
Claims (16)
1. Casting mould for manufacturing a cast part from a metal melt (S) comprising a mould cavity (5) for reproducing a cast part and comprising an inlet for pouring metal melt (M) into the mould cavity (5), characterised in that it has at least one compensation cavity (8, 9) which is linked to the mould cavity (5) via a channel (10, 11) and comprises at least one portion (8c, 9c) which is arranged above the maximum filling level (F max) of the casting mould (1) during solidification of the metal melt (S).
2. Casting mould according to claim 1, characterised in that the cross section of the channel (10, 11) is delimited in such a way as to be sealed, immediately after completion of the mould filling process, with metal melt (S) which has already solidified.
3. Casting mould according to any one of the preceding claims, characterised in that it is made of a moulding sand and a moulding material comprising a binder.
4. Casting mould according to any one of the preceding claims, characterised in that the compensation cavity (8, 9) is linked to a portion of the mould cavity (5) that is located on top while the metal melt (S) is being poured in.
5. Casting mould according to any one of the preceding claims, characterised in that it has an inspection opening (7) to the mould cavity (5) for inspecting the filling level (F) of the metal melt (S) in the mould cavity (5).
6. Casting mould according to claim 5, characterised in that the inspection opening (7) to the mould cavity (5) and the compensation cavity (8, 9) intersect a common horizontal plane.
7. Casting mould according to any one of the preceding claims, characterised in that it is composed of a plurality of moulded parts (2, 3, 4).
8. Casting mould according to claim 7, characterised in that the compensation cavity (8,
