Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a thermoforming mold for light glass. Background Technology

[0002] In the field of mobile phone lens manufacturing, glass beads need to be heated and then hot-pressed into lenses using molds. However, after the lens is formed, the upper and lower molds are completely attached to the lens. When the molds are cooled down, the lens shrinks a lot, and the bonding force between the molds and the lens can easily tear thin lenses. Utility Model Content

[0003] The main purpose of this invention is to propose a thermoforming mold for optical glass, which aims to avoid the risk of the lens breaking or even shattering under the pressure of the upper mold after the glass bead is thermo-pressed into a lens, thereby improving product yield and production efficiency.

[0004] To achieve the above objectives, this utility model proposes a thermoforming mold for light glass, comprising: a lower mold base, a lower mold, an upper mold base, an upper mold, and a buffer spring. The lower mold is detachably mounted on the lower mold base, the upper mold is detachably mounted on the upper mold base, and the lower end of the buffer spring is sleeved on the lower mold base and the lower end of the buffer spring is sleeved on the upper mold base.

[0005] A further technical solution of this utility model is that the upper mold base and the lower mold base have the same structure. The upper mold base includes a circular base plate, and the bottom middle part of the circular base plate protrudes downward to form a circular protrusion. The upper end of the buffer spring is sleeved on the protrusion.

[0006] A further technical solution of this utility model is that the top of the base plate is recessed and provided with a square mounting hole for installing the upper mold.

[0007] The beneficial effects of this utility model of a light glass thermoforming mold are:

[0008] This utility model, through the above-described technical solution, includes: a lower mold base, a lower mold, an upper mold base, an upper mold, and a buffer spring. The lower mold is detachably mounted on the lower mold base, and the upper mold is detachably mounted on the upper mold base. The lower end of the buffer spring is sleeved on the lower mold base, and the lower end of the buffer spring is sleeved on the upper mold base. After the glass marble is pressed into a lens, the buffer spring can completely separate the upper mold and the lower mold during cooling, and the lens only adheres to the lower mold. This allows the lens to quickly detach from the upper mold when the shrinkage of the lens and the mold is inconsistent, avoiding breakage or shattering, thereby improving product yield and production quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 8 This utility model proposes a thermoforming mold for light glass. A preferred embodiment of the thermoforming mold for light glass includes: a lower mold base 1, a lower mold 2, an upper mold base 3, an upper mold 4, and a buffer spring 5. The lower mold 2 is detachably mounted on the lower mold base 1, the upper mold 4 is detachably mounted on the upper mold base 3, and the lower end of the buffer spring 5 is sleeved on the lower mold base 1 and the upper mold base 3.

[0023] In this embodiment, the two ends of the buffer spring 5 are respectively sleeved on the upper mold base 3 and the lower mold base 1. During operation, the glass bead is first placed on the lower mold 2 and heated. After heating, pressure is applied to the upper mold 4 to press the glass bead into a lens. Then, the pressure on the upper mold 4 is removed, and the glass bead begins to cool. During this process, the upper mold base 3 is lifted upward by the elastic force of the buffer spring 5, thereby preventing the upper mold 4 and the upper mold base 3 from continuing to exert downward pressure on the lens due to their own weight, thus preventing the lens from breaking or shattering, thereby improving product yield and production quality.

[0024] Furthermore, in this embodiment, the upper mold base 3 and the lower mold base 1 have the same structure. The upper mold base 3 includes a circular base plate 6, and the bottom middle part of the circular base plate 6 protrudes downward to form a circular protrusion 7. The upper end of the buffer spring 5 is sleeved on the protrusion 7.

[0025] Similarly, the lower mold base 1 includes a circular base plate 6, and the bottom middle part of the circular base plate 6 protrudes downward to form a circular protrusion 7. However, when assembling the buffer spring 5, the circular protrusion 7 is placed facing upward, and the lower end of the buffer spring 5 is sleeved on the protrusion 7.

[0026] Furthermore, in this embodiment, the top of the base plate 6 is recessed to provide a square mounting hole 8 for mounting the upper mold 4.

[0027] The beneficial effects of this utility model of a light glass thermoforming mold are:

[0028] This utility model, through the above-described technical solution, includes: a lower mold base, a lower mold, an upper mold base, an upper mold, and a buffer spring. The lower mold is detachably mounted on the lower mold base, and the upper mold is detachably mounted on the upper mold base. The lower end of the buffer spring is sleeved on the lower mold base, and the lower end of the buffer spring is sleeved on the upper mold base. After the glass marble is pressed into a lens, the buffer spring can completely separate the upper mold and the lower mold during cooling, and the lens only adheres to the lower mold. This allows the lens to quickly detach from the upper mold when the shrinkage of the lens and the mold is inconsistent, avoiding breakage or shattering, thereby improving product yield and production quality.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
