Abstract

A glass molding machine includes a shaping die, a temperature controller, a die assembling state, a glass molding stage and a die disassembling stage. The shaping die includes a first, second and body molds. The die assembling stage feeds a glass material to the first mold with the body mold being fitted to the exterior of the first mold. The die assembling stage fits the second mold to the body mold to assemble the shaping die. The glass molding stage heats and molds the glass material. The die disassembling stage removes the second mold from the body mold after the molding, to remove the molded glass product. The temperature controller provides a temperature difference so that a temperature of the body mold is higher than a temperature of the second mold in the die assembling stage and in the die disassembling stage.

Description

technical field

[0001] The present invention relates to a glass forming device and a glass forming method, and more particularly to a glass forming device and a glass forming method capable of smoothly installing and removing a mold. Background technique

[0002] Recently, in order to improve optical performance such as imaging clarity, higher precision and higher resolution are required for optical components such as optical lenses. Therefore, for example, in order to make the deviation of the optical axis infinitely close to zero, it is preferable to set the gap (clearance) between the upper mold and the lower mold and the mold body to the minimum when thermoforming in the glass forming process.

[0003] On the other hand, if the clearance is set to a minimum, it will be difficult to pull out and insert the mold at the time of mold mounting and mold removal. In other words, when pulling out and inserting the mold, it is necessary to move the mold vertically in the directi...
