Utility model content
In view of this, the technical problem to be solved by the utility model is to provide a kind of polarized lenses cushion rubbers, by turning over
Side coordinating backstop fixture block limits light polarizing film, and then the flange at both ends supports for the upper/lower die of firm eyeglass simultaneously, is filled out by glue rifle
Resin raw material is filled, molded lenses are convenient and practical, and cushion rubber is made of POE, and thermoplasticity is good, need after avoiding eyeglass from forming
The trouble of secondary trimming.
In order to solve the above-mentioned technical problem, the utility model discloses a kind of polarized lenses cushion rubbers comprising outer ring body；
Be set to outer ring and cover intracorporal inner ring body, two end ring of inner ring body sets flange, and flange one end adjacent with outer ring body away from
From being set as 6mm；It is located on inner ring body and multiple backstop fixture blocks apart from one of flange 0.5mm；And it is set to outer
The protrusion extension of the external side of snare.
According to one embodiment of the utility model, wherein above-mentioned polarized lenses cushion rubber is made of POE injection molding.
According to one embodiment of the utility model, wherein above-mentioned backstop fixture block is set as 8, and circumference array is in interior snare
Internal side.
According to one embodiment of the utility model, wherein above-mentioned backstop fixture block section is triangle, limit light polarizing film is to turning over
Side.
It is set as according to one embodiment of the utility model wherein above-mentioned outer ring body is identical as inner ring set body thickness
3.5mm。
According to one embodiment of the utility model, wherein above-mentioned flange is with a thickness of 1mm.
Compared with prior art, the utility model can be obtained including following technical effect:
Light polarizing film is limited by flange coordinating backstop fixture block, then the flange at both ends supports for the upper and lower mould of firm eyeglass simultaneously
Tool, by glue rifle potting resin raw material, molded lenses are convenient and practical, and cushion rubber is made of POE, and thermoplasticity is good, avoid mirror
The trouble of secondary trimming is needed after sheetmolding.
Certainly, any product for implementing the utility model must be not necessarily required to reach all the above technology effect simultaneously
Fruit.
Detailed description of the invention
Attached drawing described herein is used to provide a further understanding of the present invention, and constitutes one of the utility model
Point, the exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the utility model
Improper restriction.In the accompanying drawings:
Fig. 1 is the polarized lenses cushion rubber perspective view of the utility model embodiment；
Fig. 2 is the polarized lenses cushion rubber cross-sectional view of the utility model embodiment.
Appended drawing reference
Outer ring body 10, inner ring body 20, flange 30, backstop fixture block 40 protrude extension 50.
Specific embodiment
The embodiments of the present invention is described in detail below in conjunction with accompanying drawings and embodiments, whereby to the utility model
How applied technology method solves technical problem and reaches the realization process of technical effect to fully understand and implement.
It is the polarized lenses cushion rubber perspective view of the utility model embodiment please also refer to Fig. 1 and Fig. 2, Fig. 1；Fig. 2 is this
The polarized lenses cushion rubber cross-sectional view of utility model embodiment.As shown, a kind of polarized lenses cushion rubber includes outer ring body 10；If
The inner ring body 20 being placed in outer ring body 10,20 liang of end ring of inner ring body set flange 30, and flange 30 and 10 phase of outer ring body
The distance of adjacent one end is set as 6mm；The multiple backstop cards for being located on inner ring body 20 and being 0.5mm apart from one of flange 30
Block 40；And it is set to the protrusion extension 50 in 10 outside of outer ring body.
In the present embodiment, body 10 ring in outer ring, which is set, has coated inner ring body 20, and the two cooperation forms inner step point
Cloth, and flange 30 is set in the both sides of the face of interior snare body 20, flange 30 can support for the upper mold and lower die of eyeglass, and built-in
In inner ring body 20 and apart from flange 30 be about 0.5mm multiple backstop fixture blocks 40, can clip light polarizing film it is adjacent one rollover
Between side 30, gap is smaller, stablizes the resin raw material for the filling that can also circulate while limit, convenient between upper and lower mould, molding
Polarized lenses are provided.It is to be understood that the molding polariscope of the utility model has degree, therefore eyeglass is thicker, and inclined
Light film needs opposite eyeglass in the outer part, therefore backstop fixture block 40 is leveled off to one of flange 30, using comfortable.Protrusion extends
Portion 50 conveniently marks, and distinguishes the cushion rubber of different photometric specifications, and facilitates finger to pinch and take.
Backstop fixture block 40 is set as 8, and circumference array is uniformly distributed in 20 inside of inner ring body, keeps light polarizing film limit
Smooth behind position, filling molding eyeglass is regular.In one embodiment, 40 section of backstop fixture block is set as triangle, has court
Outer corner prevents light polarizing film convenient, flexible, in other embodiments, can also corner rounded corner to outer end, improve resistance to
Expenditure.
Outer ring body 10 is identical as 20 thickness of inner ring body, is set as 3.5mm, regular light and handy.Flange 30 with a thickness of 1mm,
So that the both ends of the surface of eyeglass after molding have the ladder of a 1mm, avoid edge excessively sharp, inconvenience of taking.
Polarized lenses cushion rubber is molded by POE, POE, that is, polyolefin elastomer, narrow as having for catalyst using metallocene
The thermoplastic elastomer (TPE) of relative molecular mass distribution and the distribution of uniform short-chain branch.The main performance of this elastomer is very prominent
Out, it has been more than conventional elastomers in very various performance indicators, there are the superiority such as ageing-resistant, resistance to ozone, resistant to chemical media
Can, by being crosslinked to POE, the heat resisting temperature of material is enhanced, and permanent deformation reduces, and tensile strength, tearing strength etc. are main
Mechanical property is wanted all to have significant improvement.The molding cushion rubber of EVA is utilized as compared with the past, in the molding process of resin lens
In, it can be more aobvious smooth for the lateral margin of the eyeglass after solidifying, it is handled without secondary cut edge, thermoplastic stability is preferable.
Several preferred embodiments of the present invention have shown and described in above description, but as previously described, it should be understood that this
Utility model is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various
