Patent number: 11154928Abstract: A method and system for indexing moulds using a flaskless moulding machine and a mould conveyor are provided. The method comprises: (i) forming one or more moulds, each of the one or more moulds being added to the mould string while the mould string is stationary by being brought into contact with the mould string. Once the one or more moulds has been added to the mould string, the method continues (ii) by advancing the mould string, in a single continuous motion, a distance corresponding to the sum of the thicknesses of the one or more moulds, wherein (1) the moulding machine assists the mould conveyor in advancing the mould string during a first part of the distance, and (2) the mould conveyor advances the mould string a second part of the distance, corresponding to the remainder of the distance, without assistance from the moulding machine.Type: GrantFiled: April 17, 2015Date of Patent: October 26, 2021Assignee: DISA INDUSTRIES A/SInventors: Jørn Erhard Johansen, Per Larsen

Patent number: 10589347Abstract: The sand moulding machine (1) includes a moulding chamber (2) formed by a chamber top wall (3), a chamber bottom wall (4), two opposed chamber side walls and two opposed chamber end walls (7, 8). A chamber wall is provided with a sand filling opening (9) communicating with a sand feed system (10). At least one of the chamber end walls is provided with a pattern plate (12, 13) having a pattern (14, 15). 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 (18, 43) 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.Type: GrantFiled: June 12, 2015Date of Patent: March 17, 2020Assignee: DISA INDUSTRIES A/SInventors: Per Larsen, Christoffer Bay, Frederik Juhl Dynesen, Henrik Wegge, Torben Hansen, Jonas Højslet, Søren Erik Knudsen
