The sand moulding machine () includes a moulding chamber () formed by a chamber top wall (), a chamber bottom wall (), two opposed chamber side walls and two opposed chamber end walls (). A chamber wall is provided with a sand filling opening () communicating with a sand feed system (). At least one of the chamber end walls is provided with a pattern plate () having a pattern (). At least one of the chamber end walls is displaceable in order to compact sand fed into the moulding chamber. A number of compressed air inlet openings () are located in a lower part of the moulding chamber and are arranged to form an upward airflow in at least a part of the moulding chamber in order to create an at least substantially fluidised bed of sand during a sand filling operation.

Sand moulding machine and method of producing moulds

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