Abstract:
1. A press molding tool for production of a component from a first material layer and a second material layer comprising: at least one first tool part and at least one second tool part, each of the tool parts having a three-dimensional molding contour, the molding contour of the first tool part facing the molding contour of the second tool part when the first material layer and the second material layer are placed into the apparatus, the tool parts being clamped in a pressure transducer in order to bring about molding of the first material layer and of the second material layer and connection of the first and second material layers to each other by moving the first and the second tool parts together, a clamping frame device to hold the material layers in position outside the molding contours during molding, and a cutting device with a blade disposed adjacent the clamping frame device, which blade, runs in a segmental manner on the circumference of the tool parts or completely encircles the tool parts, for cutting off an excess length of all the material layers that have been molded by the tool parts, which excess length is present next to the first and second tool parts during press molding, the cutting device being movable relative to the first clamping frame element or the second clamping frame element, with the blade being moved in such a manner that a corresponding bearing region of the second clamping frame element, which bearing region faces a cutting edge of the blade, or one of the tool parts, acts as a counterposition for the cutting edge during cutting, wherein the clamping frame device comprises a first clamping frame element movable relative to the first tool part by way of a first adjusting device and a second clamping frame element movable relative to the second tool part by way of a second adjusting device, the clamping frame elements are arranged for retaining the material layers, and at least one spacer element for spacing apart the clamping frame elements in the closed position of the clamping frame elements arranged at least on one of the clamping frame elements such that, in the closed position of the clamping frame elements and during a pressing operation carried out by way of the tool parts, a continued flowing of at least one of the first and second material layers is permitted.
