Abstract

A device for shooting foundry cores with molding materials (1), comprising 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 accommodating at least one shooting nozzle (5), and a clamping head (7) associated to the shooting head (4) on its inlet side and having at least one air supply (8) for a leakproof application of compressed air to the shooting head (4), the clamping head being preferably vertically movable by means of a cylinder-piston arrangement (9), is designed and constructed for purposes of avoiding local air currents or making the air flow more uniform during core shooting in such a manner 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).
