Casting mold used for optimizing the hollow space geometry of a core of a gas turbine blade comprises an upper mold and a lower mold with inserts to modify regions of the contour sections

摘要

Casting mold comprises an upper mold (20) and a lower mold (10) which form a hollow space (50) when closed. Inserts can be placed on the upper mold and/or on the lower mold to modify regions of the contour sections. Preferred Features: At least one insert is provided with ribs, bars or nubs. Opposite regions of the contour section on the suction side and the contour section on the pressure side are provided with inserts.
