Lens production mold

Abstract

The invention discloses a lens production mold. The mold comprises a workbench, a lower mold, an upper mold, an electromagnet and a constant-temperature heating assembly; a sealing cylinder and a positioning pipe are fixedly mounted in the side edge and at the top of the workbench correspondingly. The lower mold and a positioning base are fixedly installed in the middle of the workbench; an external air valve is connected between steering cavities; the constant-temperature heating assembly is mounted in the lower mold; an exhaust hole and a forming cavity are formed in the top of the lower mold, the upper mold is arranged over the lower die mold a sealing plate is installed in the pouring pipe, a magnet block is fixed to the inner wall of the pouring pipe, a sealing pipe is fixed to the outer wall of the pouring pipe, and the middle of the sealing plate is connected with one end of a handle. The lens production mold is convenient for production, processing and forming of lenses, enables the lenses to be stably and synchronously taken out after production, is convenient and quick in taking-out operation, can effectively avoid the problem of local damage of the lenses when the lensesare taken out, and improves the forming quality of 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, ...
