Description

Technical Field

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

[0002] Lenses are an important part of glasses. They are made of optical materials such as glass and resin, have one or more curved surfaces, and are often assembled with a spectacle frame after grinding to form glasses, which are used to correct the vision of users and obtain a clear field of view.

[0003] When the existing lens forming mold works, it is necessary to heat, extrude, and then cool the material to form a complete lens. Since heating will make the core temperature of the lens forming mold very high, the lens cannot be quickly demolded, resulting in low production efficiency. At the same time, the high temperature inside the mold will also generate a large amount of thermal stress, which will cause fatigue damage to the mold material and reduce the strength and toughness of the lens forming mold. Therefore, we propose a lens forming mold to solve the problems mentioned above. Summary of the Invention
