    摘要: In the initial stage of die-opening operation when an upper core 3 moves upward together with an upper die plate 1, an upper cavity die 2 is biased downwardly by an elastic member 10 so as to press the lower surface of the upper cavity die 2 against the upper surface of a lower cavity die 6 and keep their contact, thereby forcing a molded glass element 4 to remain on a lower core 5 by utilizing the difference in outside diameter between the lower core 5 and the upper core 3. This makes it possible to securely release the molded glass element 4 from the upper core 3 and leave the molded product on the lower core 5 upon die opening, enabling smooth removal and automated transportation of the molded product.

    摘要: The present invention relates to a method of manufacturing a molded article in the form of an optical element such as a glass lens by heat-softening a glass material such as optical glass and press molding it with high precision in a pressing mold as well as an objective lens for optical picking up. The method of manufacturing comprises press-molding a molding material to make a molded articles measuring an optical property of the molded article, correcting pressing rate of at least one of the pressing molds based on the optical property thus measured, and further press-molding to make a molded article with the corrected pressing rate. A pressing device comprising a pair of pressing molds having molding surfaces processed to prescribed shape, and a means of driving one of the pair of pressing molds at a prescribed rate to press mold a molding material supplied between the pressing molds is disclosed. The device further comprises a means for detecting an optical property, a shape or a number of the molded articles and a means for controlling driving of said means of driving by correcting pressing rate of the molds based on the detected property, shape or number.

    摘要: In a method of manufacturing a glass optical element by press-forming a glass material in a chamber by using a forming mold comprising upper and lower dies at least one of which is movable, where a surrounded space is formed between the glass material and at least one of the upper and the lower dies when the upper and the lower dies come into contact with the glass material, a pressure within the chamber is reduced before the glass material placed in the forming mold is heated to a press-forming temperature. After sealing the space as formed when the glass material is in contact with at least one of forming surfaces of the upper and the lower dies, a gas is introduced into the chamber. The glass material is heated in the gas and then press-formed under a pressing load.

    摘要: A material for an optical element is accommodated between a first mold and a second mold, and is pressurized by relatively moving the first mold and the second mold while the material is heated to a predetermined temperature, thereby molding the optical element having a predetermined shape. This method determines, as a molding-reference distance, a distance between the first mold and the second mold of when a molding pressure which is generated between the first mold and the second mold applied to the material reaches a predetermined pressure, and moves either one of the first mold and the second mold from the molding-reference distance by a predetermined distance, thereby finishing molding of the optical element. Therefore, it is possible to reduce errors in the shapes of the final molding space easily and surely.
