Description

Technical Field

[0001] This utility model belongs to the technical field of acrylic convex mirror processing equipment, specifically relating to a liquid cooling device for convex mirror processing. Background Technology

[0002] Acrylic, also known as polymethyl methacrylate (PMMA), is a thermoplastic with high transparency, good weather resistance, surface hardness, and gloss. Its light transmittance is as high as 92%, and it has great processing flexibility, making it suitable for manufacturing products of various shapes, including optical components such as convex lenses. These properties make acrylic an ideal material for making convex lenses and other optical elements. Convex lenses, as an important optical component, have wide applications in many fields, such as car rearview mirrors, road reflectors, and surveillance camera lenses. Heat setting technology, as an advanced acrylic lens processing method, has significant advantages. First, by heating the acrylic material to soften it before bending or pressing, the shape and curvature of the lens can be precisely controlled to meet complex design requirements. Second, heat setting can reduce stress concentration and burr formation during processing, improving the yield and quality of the lenses.

[0003] Existing acrylic convex lens heating and shaping mechanisms cannot recover and utilize the heat generated during the heating process. If the heat generated during the heating process is directly released into the environment, it will cause a large amount of energy waste and may also cause some thermal pollution to the environment.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1

[0028] Please refer to the reference. Figure 1-5 This is the first embodiment of the present invention, which provides a liquid cooling device for processing convex mirrors, including a worktable 1, a mounting groove 2 formed in the middle of the top of the worktable 1, a heating element 3 disposed in the center of the mounting groove 2, and a lower mold 4 slidably mounted inside the mounting groove 2, and further including:

[0029] The fixing mechanism 5 is located inside the mounting groove 2, and the lower mold 4 is fixedly connected to the worktable 1 through the fixing mechanism 5;

[0030] Cooling mechanism 6 is located on the side of the lower mold 4, and a heat recovery mechanism 7 is installed inside the cooling mechanism 6.

[0031] Specifically, the fixing mechanism 5 includes a rod 501 fixedly installed inside the mounting groove 2, and a hole 502 opened at the bottom of the lower mold 4. The rod 501 is inserted into the hole 502. Threaded holes 503 are opened on the sides of both the workbench 1 and the lower mold 4. A screw 504 is threaded inside the threaded hole 503.

[0032] Furthermore: the worktable 1 is the supporting foundation of the entire mechanism, providing a stable operating platform. The mounting slot 2 is a groove for installing and positioning the heating element 3 and the lower mold 4. The heating element 3 generates heat through electric current to heat the lower mold 4, so that the acrylic material reaches a suitable softening temperature, which is convenient for subsequent pressure shaping. The lower mold 4 is a key component for shaping the acrylic material, and has a groove corresponding to the required lens shape. The fixing mechanism 5 can accurately position the lower mold 4 through the cooperation of the insertion rod 501 and the insertion hole 502, and firmly fix the lower mold 4 on the worktable 1 through the screw 504 and the threaded hole 503, ensuring that the lower mold 4 will not move or shake during processing, thus ensuring processing accuracy.

[0033] Specifically, the cooling mechanism 6 includes an inlet pipe 601 fixedly connected to one side of the lower mold 4, and a return pipe 602 fixedly connected to one side of the lower mold 4. A water pump 603 is fixedly connected to the end of the inlet pipe 601, and a storage box 604 is fixedly connected to the end of the water pump 603.

[0034] Furthermore, the coolant is drawn from the reservoir box 604 by the water pump 603, enters the lower mold 4 through the inlet pipe 601 for cooling, and then flows back through the return pipe 602, thereby rapidly cooling the shaped acrylic lens to fix its shape and prevent deformation, shortening the cooling time, improving production efficiency, and ensuring the shape stability of the lens.

[0035] Specifically, the heat energy recovery mechanism 7 includes a heat exchange box 701 fixedly connected to the end of the return liquid pipe 602. A heat exchange tube 702 is provided inside the heat exchange box 701. Both ends of the heat exchange tube 702 extend to the outside of the heat exchange box 701. Heat-conducting fins 703 are fixedly installed on the outside of the heat exchange tube 702. A connecting pipe 704 is fixedly connected to one side of the heat exchange box 701. The end of the connecting pipe 704 is fixedly connected to the liquid storage box 604. The heat exchange box 701 and the liquid storage box 604 are connected by a fixing rod.

[0036] Furthermore, the heat recovery mechanism 7 uses the heat exchange box 701 and heat exchange tube 702 to transfer the residual heat of the coolant in the return pipe 602 to the liquid in the heat exchange tube 702, thereby realizing the recycling of heat energy and reducing energy consumption.

[0037] Specifically, a support rod 8 is fixedly installed on the top of the workbench 1, a top plate 9 is fixedly installed on the top of the support rod 8, a hydraulic push rod 10 is fixedly installed at the center of the top plate 9, an upper mold 11 is fixedly installed at the bottom of the hydraulic push rod 10, and guide rods 12 are fixedly installed at the four corners of the top of the upper mold 11. The guide rods 12 are slidably installed in the through holes on the surface of the top plate 9.

[0038] Furthermore, by using hydraulic push rod 10 to push upper mold 11 to pressurize acrylic material in lower mold 4, efficient shaping of acrylic material is achieved, ensuring product precision and quality.

[0039] Working principle:

[0040] In use, the lower mold 4 is aligned and inserted through the insertion hole 502 at its bottom with the insertion rod 501 in the mounting groove 2 to ensure the initial positioning of the lower mold 4. The screw 504 is then passed through the threaded holes 503 on the side of the worktable 1 and the lower mold 4, and tightened to secure the lower mold 4, ensuring it will not move during heating and shaping of the acrylic lens. The heating element 3 is activated to uniformly heat the mounting groove 2 and the lower mold 4, bringing the lower mold 4 to the preset processing temperature. Subsequently, the hydraulic push rod 10 on the top plate 9 is activated, pushing the upper mold 11 down along the guide rod 12 until it is in close contact with the lower mold 4, applying pressure to the acrylic material placed between them. Under the combined action of high temperature and pressure, the acrylic material gradually softens and adheres. The shape of the lower mold 4 is shaped to complete the shaping process. Finally, the cooling mechanism 6 is activated, and the water pump 603 pumps the coolant in the liquid storage box 604 into the lower mold 4 through the liquid inlet pipe 601 to quickly cool the shaped acrylic convex lens to fix its shape. The cooled coolant returns through the liquid return pipe 602 and flows through the heat energy recovery mechanism 7 for heat recovery. In the heat exchange box 701, the heat-conducting fins 703 on the heat exchange tube 702 absorb the heat in the coolant and heat the liquid inside the heat exchange tube 702 to realize the recovery and utilization of heat energy. The cooled coolant inside the heat exchange box 701 is transferred to the liquid storage box 604 through the connecting pipe 704. After the lens is completely cooled, the hydraulic push rod 10 rises, and the upper mold 11 separates from the lower mold 4 to complete the demolding process.

[0041] In summary: The rapid cooling of the shaped acrylic lens by the cooling mechanism 6 significantly shortens the cooling time and improves production efficiency. At the same time, rapid cooling helps to fix the shape of the lens, prevent deformation, and ensure the shape stability of the product. The heat recovery mechanism 7 can recover and reuse the residual heat in the coolant, reducing energy consumption, improving energy utilization efficiency, meeting the requirements of energy conservation and environmental protection, and reducing production costs.
