ABSTRACT:
The present invention relates to a moulding machine (1) for producing flaskless moulds. The moulding machine (1) comprises a drag flask (3) and a cope flask (2), a drag squeeze plate (6) associated with said drag flask (3), and a cope squeeze plate (5) inserted in said cope flask (2), all arranged to be rotated between a horizontal and a vertical position and the drag flask (3) and cope flask (2) being arranged to be movable relative towards one another and away from one another. The drag flask (3), the cope flask (2), the drag squeeze plate (6), and the cope squeeze plate (5) are guided in their relative movement by a common set of guide rods (7), whereby the alignment procedure for these components is significantly facilitated.
