ABSTRACT:
The device is constituted by a prism-shaped structure which has flat faces, is internally hollow and is rotatably mounted, with preset stops, about a horizontal axis which lies at right angles to the direction of movement of the casting head. A core box is mounted on at least two oppositely arranged faces of the rotating prism-like structure and supports a lower half-mold and associated plates for extracting the finished core; each one of the lower half-molds can be placed in succession, upon rotation of the prism-like structure, at the movable upper half-mold so as to allow, by means of a single upper half-mold, to mold a core in each one of the lower half-molds and to simultaneously extract the previously finished core from the oppositely arranged half-mold.
