Abstract

THIS INVENTION AIMS AT PROVIDING AN OPTICAL ELEMENT PRESS MOLDING APPARATUS IN WHICH, WHEN PERFORMING A MOLDING METHOD WITH WHICH A MOLDING ATMOSPHERE IS SET IN VACUUM ONLY IN PRESS OPERATION, THE MOLDING CYCLE IS SHORTENED, AND ANY INFLUENCE ON TEMPERATURE CONTROL IN VACUUM ATMOSPHERE IS MINIMIZED, AND A MOLDING METHOD THEREFORE. IN ORDER TO ACHIEVE THIS OBJECT THE OPTICAL PRESS MOLDING APPARATUS, WHICH PRESS MOLDS A HEATED AND SOFTENED GLASS MATERIAL (9) BY USING A PAIR OF UPPER AND LOWER OLDS, COOLS THE GLASS MATERIAL (9), AND EXTRACTS A GLASS MOLDED PRODUCT (29) FROM THE MOLDS, INCLUDES A FIRST CLOSED CHAMBER AN ATMOSPHERE OF WHICH CAN BE REPLACED, A SECOND CLOSED CHAMBER HOUSED IN THE FIRST CLOSED CHAMBER, A MOLDING UNIT PROVIDED TO THE SECOND CLOSED CHAMBER TO MOLD THE HEATED GLASS MATERIAL (9) BY APPLYING A PRESSURE, AND A GLASS TRANSFER UNIT FOR INTRODUCING THE GLASS MATERIAL (9) LOADED IN THE FIRST CLOSED CHAMBER TO THE MOLDING UNIT IN THE SECOND CLOSED CHAMBER AND TRANSFERRING A GLASS MOLDED PRODUCT (29) MOLDED BY THE MOLDING UNIT INTO THE FIRST CLOSED CHAMBER.
