Abstract
The utility model relates to an in-mold forming lens comprising a lens layer and a functional film. The functional film is externally connected with the outer side of the lens layer; and the functional film and the lens layer are injected to be formed, wherein the functional film is in a three-layer structure, the intermediate layer is a functional film layer, and two sides of the functional film layer are optical film layers; the functional film layer adopts a polarizer, a polarizing film, a photochromic film, a three-dimensional animation effect film or a pattern color film; the optical film layer adopts a transparent optical grade plastic sheet or a film; and the functional film is glued with the optical film layers at two sides. The applied range of the lens produced through the technology is widened, the application effect of the lens is improved, and the requirements of different users are met.
Description
Technical field
The utility model relates to a kind of eyeglass.
Background technology
General eyeglass is water white, colored lens commonly used or in starting 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.
The utility model content
The purpose of this utility model provides a kind of eyeglass, can select to make dissimilar eyeglasses according to function, enlarges eyeglass range of application and effect.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of in-molded eyeglass comprises mirror plate layers and functional membrane, and functional membrane is external in the outside of mirror plate layers, functional membrane and mirror plate layers injection mo(u)lding.
Wherein, described functional film adopts three-decker, and wherein the middle 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.
Lens product through above-mentioned technology is produced enlarges eyeglass range of application and effect, satisfies requirements of different users.
The polarized light eyeglass of being produced, with similar polarized 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 other the not material of heatproof are prefabricated into sheet material by this technology, do not influence function during use.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural drawing of in-molded eyeglass;
Fig. 2 is described functional film structural drawing.
Among the figure:
1, functional rete;
2, optical film;
3, functional membrane;
4, mirror plate layers.
Embodiment
As shown in Figure 1, in-molded eyeglass described in the utility model comprises mirror plate layers 4 and functional membrane 3, and functional membrane 3 is external in the outside of mirror plate layers 4, functional membrane 3 and mirror plate layers 4 injection mo(u)ldings.
As shown in Figure 2, described functional film 3 adopts three-decker, and wherein the middle 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.
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 starting material interpolation dyestuff that is injected or in the moulding rear surface.
Claims (5)
1, a kind of in-molded eyeglass is characterized in that: comprise mirror plate layers and functional membrane, functional membrane is external in the outside of mirror plate layers.
2, in-molded eyeglass according to claim 1 is characterized in that, described functional film adopts three-decker, and wherein the middle layer is functional rete, and both sides are optical film.
