Mould-frame holding device on a mould machine for the production of boxless casting moulds

摘要

The device, in which both mould halves are produced simultaneously, consists of in each case at least one guide pipe (20) projecting downwards on either side in its outer region on the lower press plate (5), and projecting upwards on the upper press plate (6). Two guide brackets (21) slide at a fixed mutual spacing on the guide pipe (20), one or more clamp pieces (23) being seated between them which hold the guide brackets (21) and, via these, the mould frames in the assumed position by means of frictional connection.
