FEED SYSTEM Russian patent published in 2024 - IPC B22C9/08 

FIELD: foundry.

SUBSTANCE: invention relates to foundry and can be used in casting metal into moulds. Supply system (100) for metal casting comprises head (10) installed on rod-bridge (11). Head has first end (12), opposite second end (13), longitudinal axis passing between first and second ends, and continuous side wall (14) passing around longitudinal axis. Side wall forms a cavity for receiving molten metal during casting. Rod-bridge forms an open hole for connection of the cavity of the head with the casting, at that the head is installed on the rod-jumper with the first end. At the second end of the head there is at least one projection passing from the outer surface of the side wall. During casting the head is directed downwards and the second one upwards. In case of accidental action on the head after moulding, the projections on the second end of the head rest against the mould material surrounding the side wall and resist downward movement into the mould cavity.

EFFECT: preventing the head from sinking into the casting cavity.
