Abstract
The utility model discloses a nylon polarized lens which comprises a nylon material layer and a polarized film, wherein a positioning part for positioning the polarized film is formed at each of the four corners of the nylon material layer, and buffering grooves are arranged at the end surface of two opposite edges of the nylon material layer. The nylon polarized lens is suitable for manufacturing a polarized lens which has a thin mode and expensive materials, and improves the yield and the product quality.
Description
Technical field
The utility model relates to a kind of nylon polarized lenses.
Background technology
At present, common polarized lenses adopts PC material (polycarbonate) to make more, this is that gently (weight has only 1/10th of equal volume glass because the PC eyeglass has, has only half weight of conventional resins eyeglass), durable (physical property with shock resistance and resistance to deformation, under brute force is impacted, chap and do not rupture, do not have fragment to burst apart yet---so-called hardening lens), environmental protection (thermosets, recyclablely be processed into other industrial products and have reproducibility) etc. advantage, but, PC polarized lenses disadvantage is a resistance to acid not, so can't be used in the more popular sheet material framework of existing market, and produce internal stress during PC polarisation injection molding, with the process of picture frame assembling in the stress concentration phenomenon appears, when particularly cooperating with the metal picture frame, phenomenon is more obvious, even the not obvious and plastic frame of when assembling phenomenon uses and stress still can occur after a period of time and concentrate, the lighter causes the lens edge look to become, and weight person causes eyeglass to ftracture. the also more inapplicable boring of PC material.Therefore, existing polarized lenses haves much room for improvement.
Advantages such as that the nylon eyeglass has equally is light, durable, environmental protection, nylon eyeglass also have excellent low stress cracking behavior, and processing characteristics is also than PC eyeglass excellence, the first-selection of high-grade eyeglass.Therefore, adopt nylon material to make high-grade polarized lenses and become trend.
China's utility model patent 200620118294.9 is that the inventor combines the design proposal of being done at light polarizing film with eyeglass.This patent " die device of moulding eyeglass and eyeglass " discloses a kind of polarized lenses 10 as shown in Figure 1, it is the location division that four corners of its outside surface form a recess 20(respectively), on the outside surface in the zone that these four recess 20 are surrounded in order in conjunction with a light polarizing film 30; The die device that this patent also discloses this eyeglass of moulding as shown in Figure 2, comprise counterdie 40, respectively form the corresponding location division of a lug boss 50(in four corners of its top end face), a light polarizing film 30 is pasted for putting in the zone that these four lug bosses 50 are surrounded, add a patrix 60, it forms a space S near counterdie 40, and the plastics for injecting molten condition reharden into eyeglass 10.This patent is adding man-hour, earlier light polarizing film 30 is fixed on the counterdie 40 by lug boss 50, again patrix 60 and counterdie 40 matched moulds is formed the injection moulding space S, as shown in Figure 3, carry out injection moulding then, the plastics of fusion and light polarizing film 30 are combined, make polarized lenses 10.Wherein, as shown in Figure 4, surface attachment one deck viscose glue 70 of light polarizing film 30, light polarizing film 30 reduces through cutting antemarginal viscose glue 70 adhesion, in injection moulding process, as shown in Figure 5, when the plastics 80 of melt-flow pour the injection moulding space S, directly impact light polarizing film 30 edges, very easily wash away viscose glue 70, occur towards the glue phenomenon, on eyeglass, form the ripples line, as shown in Figure 6, directly influence product quality, yield rate is low.For fear of towards glue; usually on the viscose glue 70 of light polarizing film 30, adhere to one deck plastics 90 in the industry earlier; as shown in Figure 7; like this in injection moulding process; be subjected to the protection of plastics 90, can avoid the plastics 80 of melt-flow to contact and wash away viscose glue 70, thereby avoid occurring towards the glue phenomenon with viscose glue 70; guarantee product quality, improved yield rate.But so, the eyeglass that makes is thick, is generally 3 millimeter, so this patent is not suitable for making slim polarized lenses, certainly eyeglass is thick, and materials are just many, and this patent also just is not suitable for the expensive polarized lenses of material, such as the nylon polarized lenses.Therefore, existing nylon polarized lenses structure and mould all need further improvement.
In view of this, the inventor studies the problems referred to above again, develops a kind of nylon polarized lenses, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of nylon polarized lenses, to be fit to make the polarized lenses slim, that material is expensive, improves yield rate and product quality.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of nylon polarized lenses is made up of nylon material layer and light polarizing film, forms a location division for the location light polarizing film respectively in four corners of nylon material layer, is provided with dashpot at the end face of two opposite side of nylon material layer.
Two opposite side of described nylon material layer extend to form plane of orientation to both sides, form the top pin of projection respectively in four corners of two plane of orientation outside surfaces.
Four corners of described nylon material layer form the aperture that connects the location light polarizing film for the pilot pin of mould.
Four corner outside surfaces of described nylon material layer form a recess respectively, on the outside surface in these four zones that recess surrounded in order in conjunction with a light polarizing film.
After adopting such scheme, the utility model is because increased dashpot on lens structure, correspondence has increased the buffering fin on mould, so in injection moulding process, when the plastics of melt-flow pour the injection moulding space, being cushioned fin stops, can not drop on the light polarizing film edge, just can not wash away viscose glue yet, avoid towards the glue phenomenon, guarantee product quality, improved yield rate; In addition, the utility model needn't adhere to one deck plastics earlier on the viscose glue of light polarizing film as prior art, but directly adopt the light polarizing film of surface attachment one deck viscose glue to get final product, so the utility model has saved the plastics that adhere in advance, can make slim eyeglass, be approximately 2 millimeter, and reducing the job sequence of fitting together, the utilization factor of light polarizing film improves, and is more suitable for the expensive polarized lenses of material price such as nylon.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
