  • Patent number: 7984626
    Abstract: 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.

  • Patent number: 6823697
    Abstract: An object of the present invention is to provide a press forming machine for glass optical devices which is superior in the temperature uniformity and has a low manufacturing cost. An upper die is fixed to a lower end of a fixed shaft, and a lower die is fixed to an upper end of a moving shaft. The upper die and the lower die are accommodated in a quartz tube, and a forming chamber in which atmosphere adjustment is possible is formed inside the quartz tube. An infrared lamp unit is arranged so as to surround the quartz tube. The infrared lamp unit is constituted by a plurality of straight tube type infrared lamps each of which has a vertical axis, and a reflecting mirror is arranged behind each infrared lamp. In this example, straight tube type infrared lamps are used in the infrared lamp unit.
