Description

Technical Field

[0001] This utility model belongs to the field of optical mold technology, and specifically relates to an optical mold cleaning fixture. Background Technology

[0002] Optical molds often become contaminated with dust, oil, and tiny particulate impurities during use, thus requiring regular cleaning. Most existing optical mold cleaning fixtures use a closed cleaning method, where the cleaning fluid is sealed inside the cleaning chamber during operation. The optical mold is cleaned by means of spraying, soaking, or ultrasonic cleaning. In other words, existing cleaning fixtures cannot achieve the function of cleaning and draining water simultaneously, and the cleaning fluid or clean water cannot be effectively circulated and renewed.

[0003] Specifically, as the cleaning process continues, a large amount of contaminants will gradually accumulate in the cleaning solution. During the drainage stage, the cleaning solution containing tiny substances will still be in contact with the optical mold for a long time. Since the surface of the optical mold usually has high adsorption, these tiny substances can easily re-adhere to the mold surface, causing secondary pollution. This not only reduces the cleaning efficiency but also increases the number of cleaning cycles, ultimately increasing the cleaning cost. Utility Model Content

[0004] The purpose of this invention is to provide an optical mold cleaning fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an optical mold cleaning fixture, comprising a cleaning chamber, a transparent cover installed on the front side of the cleaning chamber, a turntable rotatably provided on the front side of the inner wall of the cleaning chamber, a cleaning ring rotatably provided on the edge of the turntable, three sliding grooves opened on the front side of the cleaning ring, a clamping rod slidably provided in the sliding groove by a spring, a clamping block provided on the upper part of the clamping rod, a water inlet and a water outlet opened on the cleaning chamber, and a pump head provided at the bottom of the cleaning chamber below the water inlet.

[0006] Preferably, the cleaning ring has three hollow cavities, and pushers are symmetrically arranged in the lower hollow cavities. Each pusher has a semi-circular groove on its inner side.

[0007] Preferably, a push block is provided at the bottom of the inner wall of the cleaning chamber, and conversion rings are movably arranged between the push block and the semi-circular groove on both the left and right sides.

[0008] Preferably, the height of the conversion ring is set between the push block and the pusher.

[0009] Preferably, the bottom of the pump head is connected to an inlet pipe and an outlet pipe.

[0010] Preferably, the clamping block is in the shape of an "I".

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention achieves alternating blocking and opening of the inlet and outlet by moving the cleaning ring up and down and swinging it left and right, so that the cleaning fluid or clean water can be continuously circulated and renewed during the cleaning process, avoiding the decline in cleaning effect caused by excessive accumulation of pollutants in the cleaning fluid and improving cleaning efficiency.

[0013] In this invention, the turntable drives the cleaning ring and the optical mold to roll in a small arc on the inner wall of the cleaning chamber, and the cleaning ring itself swings, so that the optical mold can fully contact the cleaning liquid, reducing cleaning dead corners caused by insufficient contact and further ensuring the cleaning effect.

[0014] This invention enables timely discharge of cleaning fluid or water, reducing the contact time between the cleaning fluid containing minute substances and the optical mold, lowering the possibility of minute substances re-adhering to the mold surface, effectively preventing secondary pollution, and ensuring the cleanliness of the optical mold.

Detailed Implementation

[0020] 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.

[0021] Example 1

[0022] like Figures 1 to 4The optical mold cleaning fixture shown includes a cleaning chamber 1, a transparent cover 2 installed on the front side of the cleaning chamber 1, a turntable 3 rotatably mounted on the front side of the inner wall of the cleaning chamber 1, a cleaning ring 4 rotatably mounted on the edge of the turntable 3, three sliding grooves 5 on the front side of the cleaning ring 4, a clamping rod 7 slidably mounted in the sliding grooves 5 via a spring 6, a clamping block 8 mounted on the upper part of the clamping rod 7, a water inlet 9 and a water outlet 10 on the cleaning chamber 1, a pump head 11 located at the bottom of the cleaning chamber 1 below the water inlet 9; the cleaning ring 4 has three hollow cavities 12, and a pusher 13 is symmetrically mounted in the lower hollow cavity 12, and a semi-circular groove 14 is opened on the inner side of each pusher 13; a pusher block 15 is mounted at the bottom of the inner wall of the cleaning chamber 1, and a conversion ring 16 is movably mounted between the pusher block 15 and the semi-circular groove 14 on both sides of the pusher block 15; the height of the conversion ring 16 is set between the pusher block 15 and the pusher 13; the bottom of the pump head 11 is connected to a water inlet pipe 17 and a water outlet pipe 18; the clamping block 8 is I-shaped.

[0023] This invention utilizes the up-and-down movement and left-and-right swinging of the cleaning ring 4 to alternately block and open the inlet 9 and outlet 10, allowing the cleaning fluid or water to continuously circulate and refresh during the cleaning process. This prevents excessive accumulation of contaminants in the cleaning fluid, which could reduce the cleaning effect and improve cleaning efficiency. The turntable 3 drives the cleaning ring 4 and the optical mold to roll at a small arc along the inner wall of the cleaning chamber 1, and the swinging of the cleaning ring 4 itself ensures sufficient contact between the optical mold and the cleaning fluid, reducing cleaning dead zones caused by insufficient contact and further guaranteeing the cleaning effect. This invention also allows for the timely discharge of cleaning fluid or water, reducing the contact time between the cleaning fluid containing microparticles and the optical mold, lowering the possibility of microparticles re-adhering to the mold surface, effectively preventing secondary contamination, and ensuring the cleanliness of the optical mold.

[0024] Example 2

[0025] like Figures 1 to 4An optical mold cleaning fixture is shown, including a cleaning chamber 1. The cleaning chamber 1 is vertical during operation and can lie flat when not in operation. A transparent cover 2 is sealed to the front of the cleaning chamber 1, allowing the operator to place the optical mold into the cleaning chamber 1 and then cover it with the transparent cover 2. The cleaning components inside the cleaning chamber 1 then clean the optical mold. Understandably, since the cleaning chamber 1 is vertical during operation, it is necessary to drain cleaning fluid, water, or a mixture of both. In this embodiment, when the cleaning chamber 1 is in a vertical position, an inlet 9 and an outlet 10 are provided at the bottom. The inlet 9 is located on the right side, and the outlet 10 is located on the left side. At the same time, a pump head 11 is provided at the bottom of the cleaning chamber 1 below the inlet 9. An inlet pipe 17 and an outlet pipe 18 are connected to the bottom of the pump head 11. That is, when the pump head 11 is in operation, the cleaning liquid can be drawn upward through the inlet pipe 17 and into the cleaning chamber 1 through the inlet 9. After use, the cleaning liquid can be discharged downward through the outlet 10 and the outlet pipe 18 into the cleaning chamber 1.

[0026] A turntable 3 is rotatably mounted on the front side of the inner wall of the cleaning chamber 1, and a cleaning ring 4 is rotatably mounted on the edge of the turntable 3. When an optical mold is fixedly mounted on the cleaning ring 4, the turntable 3 can be driven to rotate by a motor or other driving components. The rotation of the turntable 3 causes the cleaning ring 4 and the optical mold to roll in a small arc on the inner wall of the cleaning chamber 1, thereby achieving full contact between the optical mold and the cleaning liquid and ensuring the cleaning effect.

[0027] Furthermore, the front side of the cleaning ring 4 has three sliding grooves 5. A clamping rod 7 is slidably mounted in the sliding grooves 5 via a spring 6. A clamping block 8 is mounted on the upper part of the clamping rod 7. The clamping block 8 is "I" shaped and is made of a material with a certain degree of flexibility and friction, which can significantly improve the clamping force on the optical mold. In use, one side of the clamping block 8 can be pried open and moved outward, causing the spring 6 to be compressed. Then, the optical mold is inserted into the clamping block 8 and kept vertical, so that it is also inserted between the remaining two clamping blocks 8. Gradually reduce the force applied to the clamping blocks 8. The spring 6 returns to its original position and moves the optical mold inward through the clamping blocks 8. At this time, the remaining two clamping blocks 8 gradually move outward, causing the spring 6 on them to be compressed. Finally, the optical mold is moved to the center position, realizing the installation and fixation of the optical mold.

[0028] The cleaning ring 4 has three hollow cavities 12. The lower hollow cavity 12 is symmetrically equipped with pushers 13. The pushers 13 extend inward to separate the bottom of the hollow cavity 12. At the same time, semi-circular grooves 14 are opened on the inner side of the pushers 13. Then, a pusher block 15 is provided at the bottom of the inner wall of the cleaning cavity 1, between the pushers 13. The left and right sides of the pusher block 15 are movably arranged between the pusher block 15 and the semi-circular grooves 14. The height of the conversion ring 16 is set between the pusher block 15 and the pusher 13. It can be understood that the conversion ring 16 can rotate between the semi-circular grooves 14 and slide up and down on the left and right sides of the pusher block 15. In practical applications, the drive rotates the cleaning rings and optical molds on the turntable 3 and above. Under the action of the conversion ring 16 and the push block 15, the cleaning rings swing left and right during their up-and-down movement. Swinging left blocks the outlet 10, while swinging right blocks the inlet 9. The user can then drive the cleaning rings to block the outlet 10, opening the inlet 9. The pump head 11 is then activated to introduce cleaning fluid or water into the cleaning chamber 1. Once a certain water volume is reached, the pump head 11 stops operating, and the turntable 3 continues to rotate, driving... The cleaning ring swings up and down to ensure full contact between the optical mold and the cleaning fluid, guaranteeing the cleaning effect. At the same time, the rotation of the cleaning ring drives the pusher 13 to intermittently open and close the outlet 10 and the inlet 9. For the first cleaning, the pump head 11 can be opened simultaneously to maintain the water volume in the cleaning chamber 1. For the last cleaning, the pump head 11 does not need to be turned on, so that the clean water will automatically flow down through the outlet 10 and the outlet pipe 18 after cleaning the optical mold. After the first cleaning is completed, the pump head 11 can also be turned off to discharge the cleaning fluid.
