Abstract (en)
[origin: EP2460605A1] The method of producing a series of cast components, in which a casting mold (10) having a cavity and gate points is provided, comprises introducing a light metal melt by two gate points, each of which has temperature and pressure in the casting mold for producing a first cast component, where the light metal melt flows along two ways in two streams, each of which has a front in the casting mold. The fronts of the streams meet in a region of the casting mold, where the temperature and/or the pressure meet in the region, in which the streams are measured. The method of producing a series of cast components, in which a casting mold (10) having a cavity and gate points is provided, comprises introducing a light metal melt by two gate points, each of which has temperature and pressure in the casting mold for producing a first cast component, where the light metal melt flows along two ways in two streams, each of which has a front in the casting mold. The fronts of the streams meet in a region of the casting mold, where the temperature and/or the pressure meet in the region, in which the streams are measured. The measured temperature and/or the measured pressure is considered during the preparation of a second cast component in the casting mold for the selection of the respective temperature and/or the respective pressure and/or the respective trigger time point on the respective gate point during the insertion of the light metal melt. The light metal melt is: introduced into the casting mold with the pressure increased in comparison with the ambient pressure; poured as a semi-solid casting paste with a solid phase proportion; and applied at the gate points by hot runner nozzles (14, 16), whose temperature and/or pressure is adjusted. A temperature distribution and/or a pressure distribution coincidence over a specific way in the region, in which the streams are measured. An adjustment of the respective temperature and/or the respective pressure is effected at each gate point during introducing the light metal melt such that the streams meet in the same place and at the same temperature and/or the same pressure as part of tolerance intervals during the production of each individual cast component in the series. Independent claims are included for: (1) a device for producing a cast component; and (2) a cast component.
