Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a forming mold for an optical lens coating plate. Background Art

[0002] At present, with the development of science and technology, optical lenses have been widely used in technical fields such as digital cameras, mobile phones, projectors, and cameras. Optical lenses need to ensure high purity, transparency, uniformity, etc. during the production process. The industry uses various methods to manufacture optical lenses to meet the market demand for optical lenses of different specifications. At the same time, in order to reduce costs and improve efficiency, batch production is carried out to meet the demand for optical lenses.

[0003] Generally speaking, the coating process is one of the important steps in the subsequent processing. Coating refers to the use of physical or chemical methods to deposit a single or multi-layer thin film on the surface of an optical component, and utilizes the interference effect of incident, reflected and transmitted light at the thin film interface to achieve focusing, collimation, filtering, reflection and refraction effects.

[0004] During the coating process, a coating plate is generally used to fix the optical lens, thereby facilitating the coating work. Figure 1-2 The coating plate 10 processed by CNC shown in the figure needs to be provided with a positioning hole 11 for placing an optical lens and an optical lens placement space 17. At the same time, in order to meet the needs of coating, a coating plate 10 is formed as shown in the figure. Figure 3 The structure shown, in which two coated boards 10 can be joined together to snap into place with the clip 18, requires the design of a groove 12 on the coated board 10, with a ridge 13 and a retaining member 14 formed on the groove 12. Furthermore, to facilitate assembly of the two coated boards 10, a positioning block 15 and a shallow groove 16 are also required. To improve the production efficiency of the coated boards 10, a mold is required to produce the aforementioned coated boards. Utility Model Content
