Abstract

The invention discloses a preparation method of a scratch-resistant spectacle lens, which comprises the following steps of: pouring plastic into an injection molding feeding unit, heating and melting, feeding into an injection molding unit by the injection molding feeding unit, maintaining pressure, cooling, completing injection molding of an injection molding side product, pouring a special injection molding material and a replaceable spraying material into a spraying feeding unit, and carrying out injection molding on the injection molding side product. Heating and fusing to obtain a spraying side injection molding material; a sliding unit I slides to open an injection front mold and an injection rear mold in the injection unit, so that the injection rear mold carries an injection product, and the injection product is rotated to one side of a spraying unit through a rotating unit; and then the second sliding unit slides, the spraying front mold of the spraying unit and the injection molding rear mold of the injection molding unit are combined, and finally the product is taken out. The spectacle lens prepared by the invention has a good scratch self-repairing function.

Description

Technical field

[0001] The present invention relates to the technical field of spectacle lens preparation method, specifically a scratch-resistant spectacle lens preparation method. Background

[0002] The existing glasses lenses are mainly made through the injection molding process, using PMMA plastic materials, the glasses lenses are changed from glass materials to plastic PMMA materials, which reduces the weight of the product to a certain extent, improves the problem of fragile lenses, improves the feeling of belting, but it is still not good enough, the use of working conditions determines that the glasses will need to be frequently rubbed, for myopic people, when exercising, the user has to wear glasses, but the movement itself may inevitably scratch the lenses, fall, Collisions can also cause the lens to break. Suddenly, the lens is rubbed and broken, which can seriously affect the current movement of the glasses wearer.

[0003] Existing spectacle lenses cannot be repaire...
