Abstract

Die vorliegende Erfindung betrifft ein Werkzeug zum Gießen eines Formteils für die Herstellung einer Turbinenschaufel (10) mit mehreren Werkzeugblöcken (1, 2, 3, 4), die in einer vorgegebenen Weise formschlüssig zusammengesetzt einen Hohlraum (5) für das Formteil bilden, in den über einen oder mehrere Zugangsöffnungen (6) fließfähiges Material einbringbar ist. Zumindest einer der Werkzeugblöcke (1, 2) nimmt einen dreh- oder verschiebbaren Einschub oder Einsatz (7, 8) auf, der mit einer Fläche an den Hohlraum (5) angrenzt und in unterschiedliche Positionen und/oder Orientierungen gegenüber dem Werkzeugblock (1, 2) fixierbar ist, so dass in den unterschiedlichen Positionen und/oder Orientierungen des Einschubs oder Einsatzes (7, 8) unterschiedliche Hohlraumgeometrien gebildet werden.The present invention relates to a tool for casting a molded part for the production of a Turbine blade (10) with several tool blocks (1, 2, 3, 4), which are positive in a predetermined manner assembled a cavity (5) for the molded part form in the via one or more access openings (6) flowable material can be introduced. At least one of the tool blocks (1, 2) takes a turning or sliding insert or insert (7, 8) on the with a surface adjacent to the cavity (5) and in different positions and / or orientations relative to the tool block (1, 2) can be fixed, see above that in different positions and / or Orientations of the insert or insert (7, 8) different cavity geometries are formed.

Das Werkzeug ermöglicht eine nachträgliche Änderung der Geometrie des Formteils, insbesondere des Anstellwinkels, ohne hierfür neue Werkzeugblöcke fertigen zu müssen.

The tool enables a subsequent change in the geometry of the molded part, in particular the angle of attack, without having to produce new tool blocks for this.
