Abstract (en)
[origin: EP1127635A1] The invention relates to a device for casting a workpiece, especially a turbine blade with inner cooling, comprising a casting cavity (1) in which casting cores (2) which produce channels (3) that pass through the workpiece are provided. The aim of the invention is to improve a device of this type in such a way that there are no poorly cooled areas present in the workpiece. To this end, the casting cores (2) are placed in the casting cavity (1) in such a way that they rest against each other loosely.
