The invention concerns an installation for the production of ready-to-use casting shells or core assemblies, comprising at least two linearly aligned core-shooting machines or stations (1), the core-shooting machines (1) having two tool assemblies (4) which differ from each other at least slightly and which each comprise an upper tool (2) and a lower tool (3), plus identical transfer elements (5) which act as the lower tool (3) of the first core-shooting machine (1) and also convey the core (6) or core assembly along a transfer track (7) through the installation. In order to reduce the space required while ensuring an extremely simple construction, the installation is designed in such a way that the tools being used (2, 3) of the first tool assembly (4) are exchanged for tools (2, 3) of the second tool assembly (4) at the first core-shooting machine (1) after the transfer element (5) has left the first core-shooting machine with the first core (6). The tools being used (2, 3) of the first tool assembly (4) are exchanged for tools (2, 3) of the second tool assembly (4) at the second core-shooting machine (1) after the transfer element (5) has left the second core-shooting machine with the first and second cores (6), etc., until the tools (2, 3) of the tool assembly (4) at the last core-shooting station have been exchanged, so that only cores (6) produced by the same tool assembly (4) are set down on a transfer element (5). The invention also concerns a method using the installation.
