Problems solved by technology

However, in the prior art, the mold as the main part of optical lens production often has insufficient requirements for the mirror surface of the molding surface of the mold, and the flatness and processing accuracy of the mirror surface are not enough, resulting in low quality of the optical lens produced, and the existing The mold is produced and prepared by polishing after the rough molding of the mold
At the same time, during the preparation

Abstract

The invention discloses a machining technology for a mold of an LED optical lens. The machining technology includes mold rough machining, nickel electroplating and mold finish machining. Mold rough machining includes tempering forging, turn-milling forming and surface layer initial treatment of mold steel. A diamond lathe is adopted in mold finish machining for conducting ultra-high-precision machining, and therefore the surface of the mold of the optical lens can be flat. According to the machining technology for the mold, the surface layer of the manufactured mold of the optical lens can be flat through rough machining, nickel electroplating and diamond lathe ultra-high-precision machining, and the machining precision reaches the nanoscale; and meanwhile, a nickel layer is electroplated on the basis of rough machining, then finish turn-milling is conducted, and due to the fact that the nickel layer is soft in texture, when turn-milling machining is conducted, turning conducted through a diamond tool is easy, the abrasion of the diamond tool is small, and the service life of the diamond lathe is long.

Description

technical field [0001] The invention relates to the field of optical lens molds, in particular to a mold processing technology for LED optical lenses. Background technique [0002] At present, many parts of electronic products and automobiles are produced through molds. As an important element in the field of mechanical processing, molds have increasingly become the first choice for product and parts processing due to their advantages in productivity and processing costs. A mold, simply put, is a tool used to shape a product or part. According to the different molded products, the molds are divided into metal molds and non-metal molds. Metal molds are generally made by casting, and then the cast metal molds are surface treated to meet their performance requirements. [0003] Due to the various physical and chemical properties between the molding surface of the mold and the raw material to be molded, there are usually many problems at the contact surface between the molding ...
