Description
[technical field]
The utility model relates to forming model technical field, specifically a kind of mould core structure for nylon eye lens.
[background technology]
Current China is that the thermoset resin eye lens development of representative is rapid with CR39, and the glass mold wherein producing flat-top Bifocal lenses is also comparatively ripe.And as new material PA eyeglass because its outstanding performance such as height reflects, Ah's multiple is higher, safety, light, the features such as 100% uv-resistant just progressively develop, but because the production technology being thermoplastic and thermosets has the difference of internal, so many technologies, the die die holder technology being directly used in injection moulding eyeglass is especially ripe not enough.
Die of the prior art due to insert design shorter for serviceable life, and add light part sub-pieces during injection moulding and easily occur tiny overlap.And the striped that centrifugal force produces is there is when variable color spin coating, affect outward appearance.Eyeglass also easily produces the problems such as the demoulding simultaneously.
[utility model content]
The purpose of this utility model is exactly short for serviceable life in order to solve die in prior art, there is the not enough and defects such as the striped that centrifugal force produces in sub-pieces when easily there is tiny overlap and variable color spin coating, a kind of novel structure is provided, safe and reliable, can effectively extend the die life-span and the mould core structure for nylon eye lens of lifting each several part performance, comprise main leaf, sub-pieces, it is characterized in that the material of described main leaf and sub-pieces is nylon, described main leaf and sub-pieces are located on same die, the junction of main leaf and sub-pieces is connected by the cambered surface transition of different radian, described main leaf and sub-pieces are provided with polarisation diaphragm and variable color diaphragm, described polarisation diaphragm scribbles one deck glue and fits into composite structure by ejection formation in film with variable color diaphragm.
Main leaf or sub-pieces are convex lens, concavees lens, goggles, multifocal mirror or progressive lenses.
Variable color diaphragm is TAC variable color sheet, and described polarisation diaphragm is compound film sheet, and the structural sheet of compound film sheet is respectively TAC layer, PVA polarizing layer, TAC layer.
Main leaf and sub-pieces form eyeglass body jointly, and eyeglass body two sides is provided with dyed layer, and wherein one side is gradient color coating, and gradient color coating is provided with antireflecting film.
Compared with the existing technology, its advantage is that the utility model extends serviceable life and the optical stability of die to the utility model, eliminates the tiny overlap adding light part sub-pieces interface, occurs the problem of the striped that centrifugal force produces when solving variable color spin coating.And surface coating makes it have better proof stress, toughness and corrosion resistance, and this eyeglass there will not be stripping phenomenon.In addition, dawdling eyeglass also can being made to have photochromic characteristic of surface, meets the needs of vision correction simultaneously, and penetrability and hardness good.

[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model is a kind of mould core structure for nylon eye lens, comprise main leaf, sub-pieces, the material of main leaf and sub-pieces is nylon, main leaf and sub-pieces are located on same die, the junction of main leaf and sub-pieces is connected by the cambered surface transition of different radian, occurs the problem of the striped that centrifugal force produces when solving variable color spin coating.It, by main leaf and sub-pieces are designed on a die, improves life-span and optical stability, eliminates the tiny overlap adding light part sub-pieces interface.
By adding polarisation diaphragm and variable color diaphragm on eyeglass, as shown in Figure 4, by polarisation diaphragm scribbling one deck glue and fitting into composite structure by ejection formation in film with variable color diaphragm, this structure can strengthen intensity and the corrosion resistance of eyeglass.As shown in Figure 5, composite construction layer is preferably the structure that two-layer TAC presss from both sides PVA polarizing layer.
As shown in Figure 6, add that gradient color coating and the anti-reflection blast rete of antireflection can meet user to needs during nighttime driving by eyeglass two sides again.
Eyeglass is often divided into two vision areas by Bifocal lenses: to depending on being far called Yuan Yong district with what correct, looking far field; To depending on being closely called Jin Yong district, near reading range or read area with what correct.Nearly additional power equal depending on time near with the difference of focal power when looking far away, FA=FN-FD, thus near with prescription often closely to represent with additional power, prescription far away then adds a positive sphere focal power be suitable for again, as Add:FA etc.Bifocal lenses is often regarded as closely combining of two eyeglasses, namely main leaf is as looking rectification far away, and pastes on main leaf again and add a sub-pieces as looking nearly rectification, and the refractive power of this sub-pieces known should be just the nearly number of degrees with adding, certainly sometimes also can be contrary to the above, namely main leaf is looked far depending near, sub-pieces.
