Abstract
The invention discloses an in-mold forming process for lenses, which comprises the following steps: heating a functional film to be used, and bending the functional film to the curvature required by aproduct lens; placing the bent functional film into a mold cavity of the product lens, and closely attaching to a lower moulding chamber of the mold cavity; and injecting a lens material into the mold cavity, cooling, demoulding, and processing into the product. The lens product produced by the process expands the application range and effects of the lens, and meets requirements of different users.
Description
Technical field
The present invention relates to a kind of eyeglass.
Background technology
General eyeglass is water white, colored lens commonly used or in raw material, add dyestuff or the moulding rear surface painted and form the color eyeglass.For first kind of technology, defective is and can only changes light transmission rate by dyestuff, can't realize following function: elimination diffuses, the power according to incident light changes light transmission rate, 3D animation effect, passes through the accurate effect that forms of printing automatically.Though some functions also are worn easily, come off and fade after forming by surface treatment etc., and are obviously very high to technological requirement.And be easy to realize above-mentioned functions by this technology.
Summary of the invention
The purpose of this invention is to provide a kind of eyeglass, can select to make dissimilar eyeglasses, enlarge eyeglass range of application and effect according to function.
The objective of the invention is to be achieved through the following technical solutions:
A kind of in-mold forming process for lenses, stand-by functional film heating, it is stand-by to curve the needed camber of product lens; Curved good functional film is put into the grinding tool die cavity of product lens, and be adjacent to the lower mode cavity of die cavity; Inject lens materials to mold cavity, cooling, the demoulding then forms product through the processing back.
Wherein, described functional film adopts three-decker, and wherein the intermediate layer is functional rete, and both sides are optical film; Described functional rete adopts polaroid, light polarizing film, photochromic film, 3D animation effect film or pattern color film; Described optical film adopts transparent optical-grade plastic sheet material or film; Functional rete and the both sides optical film is bonding forms.
A kind of eyeglass that adopts in-mold forming process for lenses to produce comprises mirror plate layers and functional membrane, and functional membrane is external in the outside of mirror plate layers.
Lens product through above-mentioned technology is produced enlarges eyeglass range of application and effect, satisfies requirements of different users.
The polarised light eyeglass of being produced, with similar polarised light eyeglass ratio, lens thickness can be regulated by regulating the mold cavity gap, and camber is accurately duplicated by changing the core rod camber; Color can dye by injection raw material interpolation dyestuff or moulding rear surface and realize, and optical centre and geometric center are accurately duplicated by core rod is prefabricated.
Photochromic dyes or non-heatproof degree and need the material of specially treated to be prefabricated into sheet material by this technology do not influence function during use.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is described functional film structure chart;
Fig. 2 is the structure chart of product lens.
Among the figure:
1, functional rete;
2, optical film;
3, functional membrane;
4, mirror plate layers.
The specific embodiment
In-mold forming process for lenses of the present invention, 3 heating of stand-by functional film, it is stand-by to curve the needed camber of product lens; Curved good functional film 3 is put into the mold cavity of product lens, and be adjacent to the lower mode cavity of die cavity; Inject lens materials to mold cavity, cooling, the demoulding then forms product through the processing back.
As shown in Figure 1, described functional film 3 adopts three-decker, and wherein the intermediate layer is functional rete 1, and both sides are optical film 2; Described functional rete 1 adopts polaroid, light polarizing film, photochromic film, 3D animation effect film or pattern color film; Described optical film 2 adopts transparent optical-grade plastic sheet material or film; Functional rete 1 and both sides optical film 2 bonding forming.
As shown in Figure 2, the eyeglass that adopts in-mold forming process for lenses to produce comprises mirror plate layers 4 and functional membrane 3, and functional membrane 3 is external in the outside of mirror plate layers 4.
Particularly, earlier will with make transparent plastic sheet material or the film that lens materials can mix, make two films or middle compound polarization film or the sheet gone up of sheet material as polymethyl methacrylate (PMMA), polycarbonate (PC), transparent nylon (PA), PVC, TAC, materials such as CAB, PET, photochromic resin filmogen, 3D animation effect film, printing ink or coating print the materials such as film of other patterns and color and make stand-by functional sheet.Again with stand-by sheet material through cutting, hot bending becomes the required camber of eyeglass, put into the die cavity of moulds such as injection moulding or mold pressing, matched moulds inject the required thermoplastic plastic of eyeglass as: PMMA, PC, PA, PVC, TAC, PET etc. utilize mould to make cavity shape in advance and can be made into and do not have burnt or burnt eyeglass is arranged.Possessing color as need can dye at the raw material interpolation dyestuff that is injected or in the moulding rear surface.
