ABSTRACT:
An apparatus for producing a hollow foundry core, whereby core halves are first formed and fully hardened on an inner hollow-mold part and an outer mold-box half. These core halves are then sprayed with an adhesive and joined to form a finished foundry core. The apparatus reduces the production costs and improves the accuracy as to the size of the cores. The forming of the core halves on a center plate and the bringing together of the core halves respectively occurs by moving together both core-box halves in one operation.
