Abstract

A molding machine for providing flaskless molds comprising a drag flask (4) and a cope flask (3) is provided with a core setter (40) for placing cores in upwardly facing cavities of a mold located in the drag flask (4). The core setter (40) comprises a core mask (45) with pockets (49) selectively operable to hold and release cores (50), said core mask being supported by a holder (55) that is pivotally journalled around a horizontal axis to swing between a core-releasing position and a core-loading position. The core mask (45) faces downwardly towards the mold when it is in the core-releasing position and faces laterally away from said mold when it is in the core-loading position. The drag flask (4) is arranged to be movable in a substantially horizontal direction to and from a core-setting position directly under the core mask (45) in its core-releasing position. The drag flask (4) is arranged to be movable upwards to and downwards from the core mask (45) when it is in the core-setting position. When the core mask (4) has been loaded with the cores (50), it is swung to the core-releasing position. The drag flask (4) is then moved from its position under the core mask (45). The drag flask (4) is then moved up towards the core mask (45) and the cores (50) are pressed into the cavities (49) in the mold. The cores (50) are then released by the core setter (40) and the drag flask (4) moves back to its position under the cope flask (3).
