Description

Technical Field

[0001] The utility model relates to the technical field of lens production equipment, and particularly relates to an adjustable mold-closing aluminum ring. Background Art

[0002] Generally, the geometric center and the optical center of our spectacle lenses coincide. When the optical center deviates from the geometric center and the pupil center of the human eye is exactly opposite to the geometric center of the spectacle lens, a prism effect is generated. The closer the optical center of the spectacle lens is to the geometric center, the smaller the prism effect, and there will be no aberration when looking at things. However, when the optical center of the spectacle lens is farther from the geometric center, the prism effect will be greater, the aberration of things will be greater, and it will be uncomfortable to wear.

[0003] In our actual production, the problem of too high prism diopter of spectacle lenses often occurs. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide an adjustable mold-closing aluminum ring to solve one or more of the above-mentioned prior art problems.

[0005] To achieve the above purpose, an adjustable mold-closing aluminum ring provided by the utility model includes a cylindrical aluminum ring, a platform, an adjustable module, and a rotating screw. The platform is arranged inside the cylindrical aluminum ring. An installation groove is formed in the upper part of the cylindrical aluminum ring. The adjustable module is embedded in the installation groove. The rotating screw passes through the upper surface of the adjustable module and extends to the lower surface of the adjustable module.

[0006] In some embodiments, platforms are provided both above and below inside the cylindrical aluminum ring.

[0007] In some embodiments, the platform is used to place a glass mold.

[0008] In some embodiments, the adjustable module is provided with a threaded hole, and the rotating screw passes through the threaded hole and abuts against the cylindrical aluminum ring.

[0009] In some embodiments, scale lines are provided on the cylindrical aluminum ring.

[0010] Compared with the prior art, the beneficial effect of the utility model lies in that:

[0011] The height of the adjustable module can be adjusted by turning the screw of the utility model. The scale lines can mark that different heights of the adjustable module need to be adjusted for spectacle lenses with different prism diopters. According to the different prism diopters and refractive indices of the lenses, the adjusted heights need to be finely adjusted. Description of the Drawings

[0016] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] As Figures 1 to 4 shown:

[0018] An adjustable mold - closing aluminum ring, comprising a cylindrical aluminum ring 1, a platform 2, an adjustable module 3 and a rotating screw 4. The platform 2 is used to place a glass mold. The platform 2 is arranged inside the cylindrical aluminum ring 1. Platforms 2 are provided both above and below inside the cylindrical aluminum ring 1. An installation groove is opened in the upper part of the cylindrical aluminum ring 1. The adjustable module 3 is embedded in the installation groove. The adjustable module 3 is provided with a threaded hole. The rotating screw 4 passes through the threaded hole and abuts against the cylindrical aluminum ring 1. The rotating screw 4 passes through the upper surface of the adjustable module 3 and extends to the lower surface of the adjustable module 3. A scale line 5 is provided on the cylindrical aluminum ring 1.

[0019] Usage method of this embodiment:

[0020] 1. Prepare a set of molds. Through processes such as mold - closing, pouring 1.56 material, and curing, finally, the prism diopter of the lens is measured to be 0.15;

[0021] 2. Use the same set of molds. Place one mold under the mold - closing aluminum ring 1 and the other mold on top of the mold - closing aluminum ring 1;

[0022] 3. Rotate the screw 4 to raise the adjustable module 3 to 0.15 mm, which is equivalent to raising the position of one side of the mold placed on top of the mold - closing aluminum ring 1 at the same time;

[0023] 4. Then through processes such as mold - closing, pouring 1.56 material, and curing, finally, the prism diopter of the lens is measured to be 0.

[0024] In summary, in this embodiment, the height of the adjustment module can be adjusted by turning the screw, and the scale line can calibrate that different heights of the adjustable module are required for spectacle lenses with different prism diopters. According to the different prism diopters and refractive indices of the lenses, the adjusted height needs to be finely tuned, thus solving the problem of too high prism diopter of the existing spectacle lenses.

[0025] Finally, it should be noted that those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. The above embodiments and the description in the specification only illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements shall fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
