Abstract: An apparatus for shooting foundry cores or molds with a shooting arrangement (1), a set of tools comprising an upper tool (6) and a lower tool (7), and a tool change mechanism (8) rotatable about a vertical axis (10) and comprising two tool change frames (9), each of the tool change frames (9) being adapted for alternate rotation into and out of the shooting arrangement (1), is designed and constructed for optimal exploitation or utilization such that the tool change frame (9) rotated into the shooting arrangement (1) serves to receive the lower tool (7) carrying the cores (11), and that the lower tool (7) carrying the cores (11) is rotatable out of the shooting arrangement (11) and at the same time the other tool change frame (9) can be rotated into the shooting arrangement (1) with a preferably cleaned lower tool (7).
