[0002] In the process of producing contact lenses, the temporary storage and protection of copper moulds are important links to ensure their quality and finished product precision. Traditionally, copper moulds are usually placed and temporarily stored using whole-plate trays. Although this whole-plate tray design can achieve the upright placement and daily temporary storage of copper moulds, its protection function is relatively limited. Since the whole-plate tray lacks effective external protection structure, copper moulds are easily affected by external factors during storage, transfer or mailing, especially in the production of contact lenses, which is a highly demanding precision operation. This risk is particularly significant. In addition, the whole-plate tray cannot isolate air, causing copper moulds to easily oxidize on their outer surfaces when exposed to air for a long time, thereby affecting their service life, quality and the final finished product quality of contact lenses.

[0003] The traditional whole-plate tray can only meet the basic temporary storage and placement requirements in design and cannot provide comprehensive protection for copper moulds. Especially during long-term storage or logistics transfer, copper moulds are easily damaged due to collision, vibration or friction. In the face of these problems, there is an urgent need for a new device that integrates protection and storage to effectively protect copper moulds from oxidation and mechanical damage caused by external environment or improper operation, thereby avoiding surface defects in the production of contact lens products.

It should be explained that the embodiment of the utility model and the feature in the embodiment can be combined mutually in the case of no conflict.

[0027] It is understood that these descriptions are only exemplary, and are not intended to limit the scope of the utility model.

[0028] The utility model discloses a kind of copper mould core protection devices provided by some embodiments of the utility model. Figures 1-5

[0029] ​The utility model provides a device for copper moulding base protection, which can effectively protect the safety of the copper moulding base during storage, transfer and mailing, and prevent it from being oxidized and mechanically damaged. The embodiments of the utility model will be described in detail in combination with specific structures.

[0030] In a possible embodiment, the device for copper moulding base protection comprises a protective box body 100, a sealing cover 110, a sheath assembly 200 and a vibration suppression assembly 300. The protective box body 100 and the sealing cover 110 jointly form a sealed shell structure for surrounding and protecting the copper moulding base inside. The inner sides of the protective box body 100 and the sealing cover 110 are both in a hemispherical cavity structure, and are connected through a hinge on one side, which allows the sealing cover 110 to open and close around the hinge shaft. The other side of the protective box body 100 and the sealing cover 110 is provided with a matched fastener, which can firmly lock the protective box body 100 and the sealing cover 110 when the sealing cover 110 is closed, ensuring that the entire device forms a sealed spherical cavity in the combined state, thereby effectively isolating air and preventing the surface of the copper moulding base from being oxidized.

[0031] The sheath assembly 200 is located on the inner side of the protective box body 100 and the sealing cover 110, and is used for wrapping and fixing the copper moulding base. The sheath assembly 200 comprises a ring sleeve base 210, a first connecting strip group 211, a second connecting strip group 212 and a fixing lug 213. The ring sleeve base 210 has a hollow structure for accommodating the copper moulding base. The first connecting strip group 211 and the second connecting strip group 212 are symmetrically arranged on the two sides of the ring sleeve base 210 and are respectively connected perpendicularly to form an elastic sheet structure. When the copper moulding base is placed in the ring sleeve base 210, the first connecting strip group 211 and the second connecting strip group 212 can press the copper moulding base through their elasticity to ensure its stable fixation in the device. The fixing lug 213 is arranged at the end of the second connecting strip group 212, and is used for fixing the sheath assembly 200 on the inner side of the protective box body 100 and the sealing cover 110, thereby realizing the stable protection of the copper moulding base.

[0032] The vibration suppression assembly 300 is responsible for absorbing and buffering the external vibration that the copper moulding base may receive during storage and transfer. The vibration suppression assembly 300 comprises a ball seat 310, a positioning frame 320, an elastic member 340 and an energy absorption box 321. The ball seat 310 is in a cross-shaped structure, and its surface is provided with a hemispherical groove for accommodating and fixing the bottom of the copper moulding base. In order to further stabilize the copper moulding base, the surface of the ball seat 310 is also provided with a suction cup 311 made of silica gel material, which can firmly fix the copper moulding base in the ball seat 310 through vacuum adsorption, without any damage to the surface of the copper moulding base.

[0033] The positioning frame 320 is arranged above the ball seat 310 and is connected with the ball seat 310 through elastic members 340 at the bottom of the positioning frame 320. The elastic members 340 can be springs or silica gel columns, and the number is four and is distributed in a cross shape at the outer periphery of the ball seat 310. One end of the elastic members 340 is connected with the ball seat 310, and the other end is abutted with an energy absorption box 321 arranged at the inner side of the positioning frame 320. Through this design, when external vibration or impact is applied, the elastic members 340 can absorb energy and buffer, and the energy absorption box 321 further converts and dissipates the vibration energy, thereby protecting the copper mold core from damage.

[0034] In a more preferred embodiment, the sealed spherical cavity formed after the protective box body 100 and the sealing cover 110 are closed can effectively isolate external air, thereby preventing the copper mold core from being oxidized due to long-term exposure to air. At the same time, the one-piece structure and elastic design of the sheath assembly 200 ensure the tight fixing of the copper mold core, and the elastic members and the energy absorption box in the vibration suppression assembly 300 provide further vibration protection for the copper mold core, making it more secure and reliable during storage, transfer and mailing.

[0035] In summary, the utility model protects by multiple layers, integrates protection and storage, can effectively isolate the external environment, prevent the copper mold core from being oxidized and mechanically damaged, especially during long-term storage or transportation, which can better ensure the quality and safety of the copper mold core.

[0036] The working principle and use process of the utility model are as follows:

[0037] I. Working principle

[0038] The copper mold core protection device mainly provides all-round protection for the copper mold core through the cooperative action of the protective box body 100, the sheath assembly 200 and the vibration suppression assembly 300.

[0039] Protection and sealing: the protective box body 100 and the sealing cover 110 constitute the external structure of the device, and when the sealing cover 110 is closed through the hinge and locked by the fastener, a sealed spherical cavity is formed. The sealing structure can effectively isolate external air and prevent the copper mold core from being oxidized due to long-term contact with air. In addition, the sealing structure also provides basic physical protection to avoid direct damage to the copper mold core from the external environment.

[0040] Fixing and supporting: the sheath assembly 200 can press and fix the copper mold core through the action of the elastic members after the copper mold core is loaded into the ring seat through the design of the ring seat 210, the first connecting strip group 211, the second connecting strip group 212 and the fixing lug 213. The first connecting strip group and the second connecting strip group provide necessary elastic support to ensure that the copper mold core does not move in the device due to vibration or slight impact.

[0041] Vibration protection: the vibration suppression assembly 300 absorbs and buffers the vibration and impact from the outside through the interaction of the ball seat 310, the positioning frame 320, the elastic member 340 and the energy absorption box 321. The elastic member 340 is distributed in a cross shape, which can uniformly disperse the vibration energy, and the energy absorption box 321 further consumes and converts the energy, ensuring the safety of the copper mold core during storage, transfer or transportation.

[0042] II. Usage process

[0043] Preparation of the device: first, separate the protective box body 100 and the sealing cover 110 to expose the sheath assembly 200 and the vibration suppression assembly 300 inside.

[0044] Place the copper mold core: place the copper mold core into the ring seat 210 of the sheath assembly 200, and ensure that the bottom of the copper mold core is embedded in the semispherical groove on the ball seat 310. The suction cup 311 made of silica gel will firmly adsorb the copper mold core in the ball seat at this time, providing a preliminary fixing effect.

[0045] Adjust the sheath assembly: confirm that the first and second connecting strip groups 211 and 212 have tightly fitted the sides of the copper mold core through their elasticity, and firmly fix the sheath assembly 200 to the inside of the protective box body 100 and the sealing cover 110 through the fixing ears 213.

[0046] Close the device: close the sealing cover 110 through the hinge, and tightly lock it with the protective box body 100 using the fastener, to ensure that a sealed spherical cavity is formed inside the device. At this time, the copper mold core has been completely surrounded in a sealed environment, and external air cannot enter, thereby effectively preventing oxidation.

[0047] Storage or transfer: the device after being closed can be directly stored, transferred or mailed. The elastic member 340 in the vibration suppression assembly 300 will play a role in preventing vibration during the entire process, and the energy absorption box 321 further reduces the influence of external vibration on the copper mold core, ensuring its safety.

[0048] Open and take out: when the copper mold core needs to be taken out, release the fastener on the protective box body 100 and the sealing cover 110, open the sealing cover 110 through the hinge, and then take out the copper mold core from the sheath assembly 200.

[0049] Through the above usage process, the present application can efficiently and reliably protect the copper mold core, ensuring that it is not oxidized, mechanically damaged or vibrated damaged in each link, prolonging the service life and improving the quality.
