Embodiment 1
As shown in Figure 1, the recessed work surface mould 7 that the present embodiment provides includes work surface 1, end face 2 and bottom surface 3, top plane 4 it is provided with between work surface 1 and end face 2, bottom margin plane 5 it is provided with between work surface 1 and bottom surface 3, top plane 4 contacts with work surface 1 and end face 2 respectively, and bottom margin plane 5 contacts with work surface 1 and bottom surface 3 respectively.
Wherein, work surface 1 is concave surface, and end face 2 is the plane using recessed work surface mould 7 to be in top when producing eyeglass, and bottom surface 3 is then for being in the plane of bottom.
Cross section 6 is the plane determined with the intersecting lens of top plane 4 and the intersecting lens of work surface 1 and bottom margin plane 5 by work surface 1, and cross section 6 is perpendicular with central plane 10, and recessed work surface mould 7 is symmetrical about central plane 10.
In the present embodiment, the width W1 of top plane and the width W2 of bottom margin plane is 5mm, the angle theta 2 between angle theta 1 and bottom margin plane and cross section between top plane and cross section is 30 °, and the minimum thickness H of recessed work surface mould is 2.5mm.
When producing eyeglass by recessed work surface mould 7, compared to the existing recessed work surface mould for producing the eyeglass that refractive index is 1.56 and 1.6, because the width W1 of top plane and the width W2 of bottom margin plane is disposed as 5mm, and the angle theta 2 between angle theta 1 and bottom margin plane and the cross section between top plane and cross section is disposed as 30 °, therefore use die sinking cutter time can easily die sinking thus decrease the situation of recessed work surface mould 7 breakage, simultaneously, owing to adding the edge thickness of the eyeglass produced, during die sinking, the stress surface of eyeglass increases, be conducive to the dispersion of pressure during die sinking, thus effectively reduce the generation that eyeglass is damaged and/or limit is split.
Additionally, because the minimum thickness H of recessed work surface mould is set to 2.5mm, recessed work surface mould 7 is conducive to conduct heat in one-step solidification, so use existing material formula and one-step solidification program that the decorative pattern fraction defective of the eyeglass produced can be greatly reduced, the elastic deformation ability of the most recessed work surface mould 7 increases, and therefore decreases the situation of recessed work surface mould 7 breakage.
Table 1 is the fraction defective contrast table using the recessed work surface mould 7 in the existing recessed work surface mould for producing the eyeglass that refractive index is 1.56 and 1.6 and the present embodiment, and the refractive index of the eyeglass produced is 1.67.
Table 1 fraction defective contrast table
As shown in Table 1, using the recessed work surface mould 7 that the present embodiment provides, all kinds of fraction defectives are all greatly decreased, it is thus achieved that preferably effect.
As in figure 2 it is shown, the present embodiment also provides for a kind of lens mold, described lens mold includes recessed work surface mould 7, convex work surface mould 8 and adhesive tape 9, and the work surface of convex work surface mould 8 is convex surface, and adhesive tape 9 is used for being connected recessed work surface mould 7 and convex work surface mould 8.
The present embodiment also provides for a kind of eyeglass, and described eyeglass is produced by above-mentioned lens mold, and the refractive index of described eyeglass is 1.67.
Although the most only illustrating the eyeglass that refractive index is 1.67, but also can produce, by above-mentioned lens mold, the eyeglass that refractive index is 1.56 or 1.6, and also can reduce that eyeglass decorative pattern, eyeglass be damaged, eyeglass limit is split and fraction defective in mould breakage.
When the lens mold provided by the present embodiment produces eyeglass, especially refractive index is the eyeglass of 1.67, efficiently solve the eyeglass problem that easily breakage and/or limit are split, simultaneously, reduce eyeglass decorative pattern fraction defective, decrease the situation that lens mold is damaged, thus greatly improve the production qualification rate of eyeglass, decrease the scrappage of lens mold.
Embodiment 2
The present embodiment differs only in embodiment 1, the present embodiment provides various sizes of recessed work surface mould 7, the width W1 of top plane and the width W2 of bottom margin plane is 4.5mm, the angle theta 2 between angle theta 1 and bottom margin plane and cross section between top plane and cross section is 30 °, the minimum thickness H of recessed work surface mould is 3mm, table 2 is the fraction defective contrast table using the recessed work surface mould 7 in the existing recessed work surface mould for producing the eyeglass that refractive index is 1.56 and 1.60 and the present embodiment, the refractive index of the eyeglass produced is 1.67.
Table 2 fraction defective contrast table
As shown in Table 2, although the recessed work surface mould in the present embodiment is slightly lower compared to the decrement of the recessed work surface mould fraction defective in embodiment 1, but the most close, existing fraction defective is also greatly reduced, thus obtains preferably effect.
Although the foregoing describing detailed description of the invention of the present utility model, it will be appreciated by those of skill in the art that this is merely illustrative of, protection domain of the present utility model is defined by the appended claims.These embodiments, on the premise of without departing substantially from principle of the present utility model and essence, can be made various changes or modifications, but these changes and amendment each fall within protection domain of the present utility model by those skilled in the art.
