<p>The invention relates to a casting tool for the production of castings, particularly for the production of cores (90) for sand castings, comprising a supporting device consisting of a first and a second supporting unit (10, 20, 50, 60) capable of being moved in a joining direction (2) toward each other, and comprising at least two mold elements (30, 40), of which a first mold element (30) is attached to the first supporting unit (10, 20) and a second mold element (40) is secured to the second supporting unit (50, 60), which mold elements (30, 40) each have a mold recess (33, 43), which mold recesses (33, 43) in the mold elements (30, 40) together define the shape of at least one casting core to be produced (90) when the first and second mold elements (30, 40) bear against each other. According to the present invention, one of the supporting units (10, 20) has a first peripheral frame (20) that surrounds the mold element (30) attached to said supporting unit (10, 20), and the frame (20), as multi-segment frame, is composed of at least two frame segments (22, 24, 26) joined together by positively effective securing means. The use thereof as a very simply and quickly produced core-casting tool.</p> |
