no. 2 Embodiment approach

[0100] In the example of the above-mentioned first embodiment, the cam plates 70, 80 and the spring plate 86 are used to control the swing of the pod 10 (molding die 12), but other driving mechanisms such as a gear mechanism, a link mechanism, and a hydraulic mechanism may also be used. Shake control for pods. In the example of the second embodiment of the present invention described next, the pod swing is controlled using a gear mechanism. In the following description of the second embodiment, points different from the first embodiment will be mainly described, and the same or similar reference numerals will be used for the same or similar components as those of the first embodiment, and detailed description thereof will be omitted.

[0101] Figure 7 It is a front view of the glass gob shaping|molding apparatus 100 of 2nd Embodiment of this invention. Like the first embodiment, twelve pods 110 are attached at intervals of 30° around the rotation central axis Ca on the peri...

no. 3 Embodiment approach

[0111] In the examples of the first and second embodiments described above, a vertically placed turntable was used, but the present invention can also be applied to an apparatus in which the turntable is placed horizontally. Next, a description will be given of a third embodiment of the present invention using a horizontally placed turntable.

[0112] Figure 11 It is a top view of a glass gob forming apparatus 200 according to a third embodiment of the present invention, Figure 12 for its side view ( Figure 11 View in the direction of arrow I). In the present embodiment, the rotary motor 30 and the disc-shaped rotary table 220 are arranged horizontally (that is, the rotation central axis Ca faces the vertical direction).

[0113] The glass block forming apparatus 200 includes an elevator 250 whose driving device moves up and down as a whole; The rotary electric machine 30 is attached to the upper surface of the central portion of the chassis 242 , and the rotary table 2...

Abstract

The invention relates to a glass block manufacturing device, a glass block manufacturing method, a glass manufacturing method, and an optical element manufacturing method. The glass block manufacturing method inhibits movement of a glass block in a forming mould caused by glass block manufacturing intermittently driving the forming mould. The glass block manufacturing method comprises intermittently moving the forming mould supplied with fused glass and cooling the forming mould in order to form the glass block, and shaking the forming mould around a shaking shaft vertical to a horizontal shaft in the moving direction of the forming mould in order that the forming surface of the forming mould faces a prescribed inclination angle inclined with respect to a vertical shaft.

Description

technical field [0001] The present invention relates to a glass gob manufacturing apparatus and a glass gob manufacturing method for producing a glass gob from molten glass using a molding die, and a method for manufacturing a glass molded article and an optical element from the above glass gob. Background technique [0002] A known glass gob manufacturing apparatus receives molten glass flowing down from a molten glass supply unit in a floating state with a molding die, and shapes it into a glass gob (glass gob or blank) for precision press molding. The specific structure of such an apparatus is described in Patent Document 1, for example. [0003] In the glass block manufacturing apparatus of Patent Document 1, a plurality of molding dies are arranged at equal intervals in the circumferential direction on a horizontal turntable, and the turntable is intermittently rotated to sequentially transfer each molding die to a predetermined stop position. Thereby, molten glass is ...
