Description

Technical Field

[0001] The utility model relates to the technical field of lens molds, in particular to a lens mold. Background Art

[0002] Lens molds are molds used to make lenses. Lens molds are usually made of silicone or metal, with precise surface processing and structural design to ensure the quality and accuracy of the lens. Lens molds can be used to make various types of lenses, including convex lenses, concave lenses, spherical lenses, aspherical lenses, etc. Lens molds are usually used for products such as vehicle headlight lenses, camera lenses, and eyeglass lenses. There are at least the following disadvantages in the use of existing lens molds: 1. During the use of existing lens molds, the upper mold lacks a limit during the movement of the lower mold, which can easily cause the upper mold to shift after long-term use, resulting in defects in the finished lens, thereby increasing corporate losses; 2. During the use of existing lens molds, due to the curvature of the lens, the processed lens is not easy to remove, which increases the operating burden of the staff. Therefore, we launched the lens mold. Utility Model Content
