摘要： A manufacturing method for an optical glass element having a refractive index equal to a design value after press-molding. A glass material of specified composition is melted and press-molded while it is in the molten state. The refractive index of the glass material is calculated by substracting a change in the refractive index of the glass material resulting from the press-molding from a required refractive index for a molded glass element.

摘要： A lens is manufactured by preparing a glass material, preparing a molding apparatus for pressmolding the glass material into a lens shape, preheating the glass material or heating the glass material in the molding apparatus to soften the glass material and molding the glass material into the lens shape by the molding apparatus. An engagement portion of the molded lens to a member on which the lens is to be mounted is molded in the molding process simultaneously with the molding of an optically function portion of the lens.

摘要： Disclosed is a glass molding process using an apparatus for manufacturing a glass preform into a glass molded product. In the process a mold is prepared for pressing the glass preform. The mold consists of a pair of molds having a cavity surface for forming the glass molded product, and a frame mold which is movable against the pair of molds and incorporates a heating source. A next step in the process involves introducing the glass preform, where the pair of molds are opened and the glass preform is placed on the cavity surface. The glass preform then undergoes heating, where the glass preform is moved so as to come near the heating source of the frame mold by closing the mold, thereby heating the glass preform. The glass preform is then pressed by moving the mold to mold a shape of a glass molded product. The resulting glass molded product is then separated from the heating source by moving the frame mold and taken out by opening the mold.
摘要翻译： 公开了一种使用玻璃预成型体制造成玻璃成形品的装置的玻璃成型方法。 在该过程中，制备用于压制玻璃预制件的模具。 模具由具有用于形成玻璃模制产品的空腔表面的一对模具和可抵靠该对模具移动并结合有加热源的框架模具组成。 该过程的下一步涉及引入玻璃预成型件，其中打开一对模具并将玻璃预制件放置在空腔表面上。 玻璃预成型件然后进行加热，玻璃预制件通过闭合模具而移动到框架模具的加热源附近，从而加热玻璃预制件。 然后通过移动模具来压制玻璃预成型件以模制玻璃模制产品的形状。 然后通过移动框架模具并通过打开模具取出所得到的玻璃模制产品与加热源分离。

摘要： A method of pressing flowing-down molten glass from the opposite sides thereof by a pair of shaping mold members to thereby manufacture a glass optical part having surfaces corresponding to the shaping surfaces of the mold members is characterized in that a groove forming ring is provided around the shaping surface of at least one of the shaping mold members, a groove is formed in the molten glass by the groove forming ring during the press and the flowing-down molten glass is cut above that portion thereof which is being pressed, thereby obtaining a glass molded article having an ear protruding outwardly of the groove relative to an optical part body portion.
