Description

A kind of manufacturing method of myopia polarized resin spectacle lens

Technical field

The present invention relates to a kind of spectacle lens, more particularly, to a kind of manufacturing method of near-sighted polarized resin spectacle lens.

Background technique

It is well known that sunlight is radiated at sand ground, the water surface, snowfield, the reflected glare that will form on road surface, it often will cause eyes Uncomfortable and fatigue.Near-sighted polarized ophthalmic lenses are made of the polarization theories according to light, it can by this this random scatters light, It is effectively arranged and is filtered out, so that light is organized into light in the same direction and enter eyes, periphery scenery is made to seem soft without piercing Eye, has the function of unique preferential elimination dazzle, thus uses computer and viewing TV for a long time for myope, and run The outdoor activities such as step, swimming, mountain-climbing, fishing, cycling, especially near-sighted driver have special effect, can improve vision, increase frame Multiply enjoyment.Since the right and left eyes degree of myopia is different, range of degrees is big, if the near-sighted polarized ophthalmic lenses of myopia apolegamy are not Good, the degree of near-sighted polarized ophthalmic lenses and the degree of myopia mismatch, and will feel that dizzy eye is swollen, if but myopia wearing It is suitble to the near-sighted polarized ophthalmic lenses of oneself myopia degree, is to fully achieve to wear to carry the effect of near-sighted polarized ophthalmic lenses.Cause This wears near-sighted polarized ophthalmic lenses to adapt to myopia, and the right and left eyes degree and range of degrees of near-sighted polarized ophthalmic lenses are also very It is more.

Currently, the molding of near-sighted polarized ophthalmic lenses is completed by handmade in the prior art.Upper mold is fixed In the upper part of sealing rubber ring, polaroid is fixed among sealing rubber ring, and lower die is fixed on the lower part of sealing rubber ring, by close Resin liquid is filled between upper mold and polaroid and lower die and polaroid by the aperture on sealing rubber ring, then will tree by mold heating Rouge solidification, then demould and produce a kind of near-sighted polarized ophthalmic lenses for having degree.When the near-sighted polaroid glasses that manufacture another degree It is mobile it is necessary to lower die when piece, so that ophthalmic lens edge distance is adjusted to 11b by 11a, thus just need to exchange another kind and the degree The sealing rubber ring of matching forms a closed casting type chamber with upper die and lower die, and the myopia of another degree could be made partially Optical glasses piece, that is to say, that a kind of every near-sighted polarized ophthalmic lenses for manufacturing degree will exchange a kind of sealant of dimension Circle, the specification type of sealing rubber ring is more, for example nearsighted eyeglass does not just have 297 not from 0 to -8.00 or in 0 to -2.00 range of astigmatism With the spectacle lens of degree, it is necessary to which thus the sealing rubber ring of 297 kinds of different sizes can bring following problems：First is that casting type chamber More specification large-scale productions cannot be formed, thus keep polarized ophthalmic lenses manufacture efficiency low, high production cost；Second is that due to sealant Loop-shaped is much like and wide in variety, is not easy to manage, and sealing rubber ring manufacturing cost is costly, and is easy to happen and misuses, and causes to produce Product are scrapped；Third is that, due to sealing rubber ring poor surface quality, leading to sealant when the sealing rubber ring of same degree is reused Leakproofness decline is enclosed, product quality is influenced.

Summary of the invention

The problems of during manufacturing for above-mentioned polarized ophthalmic lenses near-sighted in the prior art, the present invention provides one kind The manufacturing method of multi items myopia polarized resin spectacle lens large-scale production.

The manufacturing method of myopia polarized resin spectacle lens of the present invention is：First by upper mold and with the polaroid of fluid-through port It is separately fixed in support ring, moves support ring still further below, make support ring movable supporting on circular orientation mould, then will be in lower die It moves and cooperates with circular orientation mould, a prefabrication type chamber being made of support ring, upper die and lower die and circular orientation mould is formed, under making The distance at mould upper surface to polaroid center be setting center away from, then lower die moves down, then circular orientation mould is removed, It is set as beginning edge thickness by spectacle lens degree, then lower die is moved upwards up to corresponding adjustment edge thickness, will supports Ring and lower die synchronous rotary make support ring and lower die side be coated with adhesive tape, form one by support ring, upper die and lower die and glue With the closed casting type chamber constituted, then casting type chamber being removed and is transferred to casting process casting, heating solidifies resin eyeglass, It demoulds again and produces near-sighted polarized ophthalmic lenses.

The present invention does not use sealing rubber ring, but in the prior art basis for producing common spectacles piece in enormous quantities, it will Existing sealing rubber ring is changed to support ring and circular orientation mould, i.e., is first fixed on polaroid and upper mold in support ring together, then Support ring is placed on circular orientation mould top, then lower die is placed on circular orientation mould lower part, formed one by upper mold+polaroid+ The casting type chamber that adhesive tape and lower die are constituted, casting type chamber is controlled on automatic adhesive tape machine by computer and is molded.

The present invention compared with the prior art in near-sighted polaroid glasses piece making method, major technique innovative point：First is that will show There is the sealing rubber ring for rising in technology and fixed upper mold and polaroid and closing and lower die being supported to position to be designed to mutually matched Two parts, some are the support ring for supporting fixed upper mold and polaroid, and another part is the circular orientation mould that lower die just positions； Second is that coating support ring and lower die side using adhesive tape to form the closing being made of support ring, upper die and lower die and adhesive tape Casting type chamber, then be poured in adhesive tape layer interface aperture, then the fluid-through port passed through on polaroid completes near-sighted polarisation eye The moulding by casting of eyeglass.

The present invention has the characteristics that compared with existing near-sighted polarized ophthalmic lenses forming method：

1, only achieve that support ring, the both horizontally and vertically first of upper die and lower die are determined with a kind of circular orientation mould of specification Position recycles computer control lower die to move up different distances, reaches different adjustment edge thickness 11b, so that it may realize not Lower die with degree positions；

2, circular orientation mould only plays the first positioning action of upper die and lower die, does not form casting type chamber with upper die and lower die, fixed just Position after, circular orientation mould exits, without same degree spectacle lens keep center away from size constancy under, from computer control lower die to On be moved to different adjustment edge thickness 11b, so that it may constitute different degrees with by support ring, upper die and lower die and adhesive tape Casting type chamber carrys out casting complete,

As long as 3, a kind of realize the circular orientation mould just positioned, the sealing rubber ring of more specifications is not needed, can not only be realized not unison Number polarized ophthalmic lenses large-scale production, improves production efficiency, reduces production cost, and is conducive to improve product quality,

4, the influence that can be cut down the number of intermediate links, substantially reduces die cost, convenient for management, saves die cost.
