A high-precision glass molding machine

Abstract

The invention relates to the technical field of glass molding equipment, and discloses a high-precision glass molding machine, including a lower mold, the outer surface of the lower mold is movably connected with a connecting sleeve through a pin-connected connecting rod, and the connecting sleeve The bottom of the outer surface is fixedly fitted with clamping helical teeth, and the top of the connecting sleeve is provided with a groove. The active socket has an upper die. In this high-precision glass molding machine, the expansion air bag is set so as to use the pressure generated by the expansion of the inert gas filled in it to squeeze the glass raw material on the glass molding machine and mold it into The specific shape does not require other power output devices, thereby effectively reducing the power consumption of the glass molding machine in the working process, and at the same time reducing the preparation and maintenance costs of the glass molding machine.

Description

technical field [0001] The invention relates to the technical field of glass molding equipment, in particular to a high-precision glass molding machine. Background technique [0002] Glass compression molding is a high-precision optical element processing technology. It heats the glass raw material and the mold together to the softening point of the glass in a non-oxidizing atmosphere, and the glass and the mold are at the same temperature (higher than the glass temperature). Softening point 50°C) under the condition of using the mold to press the glass, and then cooling the mold so that the temperature drops below the softening point of the glass while maintaining the pressure, and then can be directly molded at one time to meet the use requirements. Optical components have brought new changes and developments to the optical system design of optoelectronic instruments. [0003] However, when the existing glass compression molding technology applies pressure to the glass ne...

Problems solved by technology

[0005] The invention provides a high-precision glass molding machine, which can automatically apply pressure to the mold by utilizing thermal expansion and contraction, and does not need other power output equipment for the glass molding machine, reducing the cost of the glass molding machine. The machine has the advantages of low power consumption, preparation cost and maintenance cost during operation and wide application range, which solves the need to configure additional power when the existing glass molding technology presses the glass near the softening point The output device is used to apply pressure to the mold, which leads to a large power consumption of the glass molding machine during the working process. Moreover, because the mold operates under high temperature conditions, in order to ensure the accuracy of the glass molding machine, The power output equipment needs to be made of high-temperature-resistant materials, which increases the preparation and maintenance costs of the glass molding machine, and the scope of application is small.
