A lens production mold

Abstract

The invention discloses a mold for lens production, which comprises a working table, a lower mold, an upper mold, an electromagnet and a constant temperature heating assembly. The middle part of the table is fixed with a lower mold and a positioning seat, and an external air valve is connected between the steering chambers, and a constant temperature heating assembly is installed inside the lower mold, and the top of the lower mold is provided with an exhaust hole and a molding cavity. The upper mold is arranged directly above the lower mold, a sealing plate is installed inside the casting tube, and a magnet block is fixed on the inner wall of the casting tube, a sealing tube is fixed on the outer wall of the casting tube, and the sealing plate One end with a handle is connected to the middle part. The lens production mold is convenient for the production, processing and molding of the lens, so that the lens can be taken out stably and synchronously after production. The taking out operation is convenient and fast, which can effectively avoid the occurrence of partial damage of the lens when taking it out, and improve the molding quality of the lens production.

Description

technical field [0001] The invention relates to the technical field of lens production, in particular to a lens production mold. Background technique [0002] Lenses are commonly used accessories of optical devices in social life on the spot. Through the installation and use of lenses, the refraction, scattering and reflection of optical light are carried out, so that the optical devices have different types of functions when they are in use. Work study and experimental data analysis provide the equipment foundation and play an active role in the progress and development of the society. In the production and processing of lenses, in order to adjust the initial positioning of the shape and size of the lenses, the molds are used to limit the forming of the lenses, so that the forming The size and size of the final lens are more in line with its production and use requirements, which is convenient for subsequent processing, grinding, polishing and molding, and other processes, ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a lens production mold to solve the above-mentioned background technology. It is proposed that the existing lens production mold is inconvenient to take out the lens after forming when the lens is produced and processed, and it is easy to appear at the edge when the lens is taken out. If the problem is damaged, the production efficiency of the lens will be reduced, the quality of the production molding will be reduced, and the rapid production of the lens will be affected. After forming, when the upper and lower molds are separated, the rapid removal of the lens is directly completed, resulting in the additional use of the removal structure, which reduces the production and processing speed of the lens, and there are limitations and defects in the use of the mold itself.
