Abstract
The apparatus for shaping thermoplastic materials, in particular for producing moulded parts with a large height of the moulded part, comprises a suction-pressure bell and a lower part which can be locked to each other by a locking device. Resting on the lower part are a mould and a clamping frame, while the upper clamping frame can be securely clamped by working cylinders. In the locked state, the clamping frames are braced by a seal, which is arranged between the suction-pressure bell and the upper clamping frame. The seal extends over the entire circumference of the suction-pressure bell and is able to be pressed against the upper clamping frame by a pressure medium.
