Process for the production of an optical lens in polymer material and corresponding device

摘要

Apparatus has a closing element (12) with two jaws (12',12) whose internal surfaces are covered with synthetic material and grip two mold shells. The jaws are movable relative to each other. Each jaw may be made of metal and has a semi-cylindrical internal surface for gripping the edges of the mold shells. The jaws are mounted in a frame (19). The upper or lower jaw is movable vertically and the other jaw is fixed. Double acting jacks (29) move the jaw.
