Production of a three-dimensional metallic hollow mold comprises acquiring the geometry data of the mold using suitable computer software, and generating CNC processing data for the high speed cutting of molds

摘要

Three-dimensional metallic hollow mold production comprises acquiring 3D CAD mold geometry data; and generating CNC processing data for high speed cutting of molds corresponding to negative intermediate mold (2). The negative mold separates into at least two block-like half shells (4, 5) having mold-determining inner contour (15), and is provided with one or more mold cores for hollow chambers. Preferred Features: The structures given by the geometry data are modified in the region of the inner contour of the hollow mold with a corresponding over-measure.
