A device for shooting foundry cores or moulds with moulding materials (1) has a shooting head (4) with an inlet side (2) and an outlet side (3), a shooting plate (6) located at the outlet side of the shooting head (4) and bearing at least one shooting nozzle (5) and a clamping head (7) located at the inlet side of the shooting head (4) and having at least an air supply (8) for sealing the shooting head (4) by applying compressed air thereon. The clamping head (7) is preferably movable vertically by means of a cylinder-piston arrangement (9). In order to avoid local air currents or to make the air flow more uniform during core shooting, said device is designed in such a way that a device (10) for swirling or uniformly distributing the compressed air that flows from the air supply (8) into the shooting head (4) is arranged between the shooting head (4) and the clamping head (7).
