    摘要: A press forming machine for optical devices which manufactures, an optical device from silica glass with a high glass transition point. A transparent quartz tube surrounds an upper die unit, lower die unit, fixed shaft, and moving shaft to form an airtight chamber inside it. Infrared lamps are arranged along the outer surface of the transparent quartz tube, and a reflecting mirror is arranged behind the infrared lamps. A cooling gas jacket is formed to cover the rear surface of the reflecting mirror. The inner-diameter side wall surface of the jacket and the reflecting mirror have many through holes. A cooling gas is sprayed from the interior of the jacket toward the transparent quartz tube through the through holes, thereby cooling the reflecting mirror, quartz bulbs constituting the outer surfaces of the infrared lamps, and the transparent quartz tube.

    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: In press molding, a shaft (metal mold 13) is moved by positional or torque control to cause upper and lower molds to reach a set position slightly before a position where the upper and lower molds are set in a final mold closed state. As soon as the upper and lower molds reaches the set position, the control is switched to torque control using a small force which does not deform a glass material to perform feedback control. For this reason, when the cooling process is started, the mobile shaft is moved by the same amount as a contraction amount of the shaft, the actual position of the shaft is moved. However, a tight contact state between the molds and the glass material is kept without changing the thickness of the glass material, and positional control and torque control can be apparently performed at once. Thereafter, when temperature reaches an almost glass transition point, final pressing is performed. A position where the material is press-molded is exactly controlled by correcting an origin position of lower mold by closing the molds before press-molding. According to this method, a highly accurate optical element having thickness reproducibility can be obtained.
