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.

Abstract: The present invention is directed to reduce the total footprint of a press forming system for glass having a plurality of press units, and also to increase an actual availability of each press unit. A plurality of press units are arranged in two parallel rows and a first transfer robot is arranged at the center of the space between the two rows. In adjacent of the moving area of the first transfer robot, a palette changer is arranged. A tray in use is mounted on a first base of the palette changer and a stand-by tray before use is placed on a second base. Blanks and formed products are stored in the tray. Press units equipped with second transfer robots, respectively. In front of the press units, intermediate transfer points are respectively provided for temporarily storing a blank and a formed product.

Abstract: An object of the present invention is to enable to use a common transfer machine for transferring performs to and for transferring products from a press-forming system for glass having a plurality of press units. The press-forming system for glass has a plurality of press units. A linear moving stage is arranged in the proximity of the press units. A transfer robot is mounted on the linear moving stage. A pallet changer is arranged in the proximity of an end of the linear moving stage. A tray presently in use is mounted on a first mount and a new tray on standby is mounted on a second mount on the pallet changer. The inner space of the tray is partitioned into sections so as to correspond to press units in number. In each section, a plurality of pockets is arranged for storing preforms or products one by one.

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.
