Abstract:
1. A press molding tool for production of a component from at least one first material layer and one second material layer with at least one first tool part and one second tool part each having a three-dimensional molding contour, wherein, when the first material layer and the second material layer are placed into the apparatus, the molding contour of the first tool part faces the first material layer and the molding contour of the second tool part faces the second material layer, wherein the tool parts are clamped in a pressure transducer in order to bring about the molding of the first material layer and of the second material layer and the connection of the two material layers to each other by moving the first and the second tool part together, and with a clamping frame device in order to hold the material layers in their closed position outside the contour region of the tool during the molding operation, wherein the clamping frame device comprises a first clamping frame element which is movable relative to the first tool part by means of a first adjusting device, a second clamping frame element which is movable relative to the second tool part by means of a second adjusting device, and a third clamping frame element which is movable relative to the first or second tool part by means of a third adjusting device and is arranged between the first and the second clamping frame elements, said first, second and third clamping frame elements being moveable relative to each other by the respective first, second and third adjusting devices such that a first material layer can be held between the first and third clamping frame elements and a second material layer can simultaneously be held between the second and third clamping frame elements, such that the first material layer and the second material layer are able to flow relative to each other during the molding of the layers, and the press molding tool comprises at least one cutting device arranged on the third clamping frame element with a cutting element which is movable relative to at least one of the tool parts, and as seen in the opening and closing direction of the tool parts, runs in a segmental manner on the circumference of the tool parts or completely encircles the latter, for cutting off an excess length of at least one of the material layers, which excess length is present next to the two tool parts during the press molding.
