Abstract
The mold wall forms the boundary of a cavity provided with a filling opening and is divided vertically into several segments, which are connected to each other in such a way that they can separate under the action of a force acting outward from the cavity. At least one pretensioned elastic element is installed outside the cavity, which is in effective contact with at least one segment, so that, because of the pretension, an elastic force acts on the segment in the direction toward the cavity. A tensioning element is provided to pretension the elastic element, this tensioning element being installed outside the mold wall to serve as an abutment for the elastic element, and that the elastic element be made of a creep-resistant material.
