ABSTRACT:
The invention concerns a molding unit comprising, between two components consisting of a mold element (22) and its support (18), a compensating chamber (56) wherein a pressurized fluid is injected to move apart the mold element (22) from its support (18). The invention is characterized in that the chamber (56) is delimited by a membrane (42) comprising a peripheral seal (44) with a lip, the membrane (42) being urged to press against one of the components (22, 18) and the seal lip (44) being urged to be tightly pressed against the other of the components (18, 22).
