Abstract
Description
Technical Field
[0001] This application relates to the field of lens manufacturing technology, and in particular to a molding apparatus for lens products. Background Technology
[0002] As a core component of optical systems, lenses are widely used in many fields such as photography, medical equipment, semiconductor manufacturing, and aerospace. With the rapid development of various industries, the market demand for lenses continues to grow, while at the same time, more stringent requirements are being placed on the precision, quality, and production efficiency of lenses.
[0003] Currently, most molding equipment on the market requires heating the lens raw materials during the molding process to soften them at a specific temperature so that they can be accurately formed under external force. However, after the lens is molded, it is impossible to quickly cool it down. Due to the slow cooling process, the lens remains at a high temperature for a long time, which can easily cause deformation due to uneven stress release during the cooling process. This affects the dimensional accuracy and surface flatness of the lens, reducing product quality. To address this issue, we propose a molding device for lens products. Utility Model Content
[0004] The purpose of this application is to provide a forming apparatus for lens products to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A forming device for lens products includes a base, a bottom mold disposed above the base, a forming structure disposed above the bottom mold, a cavity being formed inside the bottom mold, and a cooling mechanism for rapidly cooling the bottom mold disposed above the base. The cooling mechanism includes a liquid storage tank disposed above the base, a pump body mounted on the front of the liquid storage tank, a pump body output end connected to the front of the liquid storage tank via a suction pipe, an annular pipe connected to the output end of the pump body, and annularly arranged drain pipes connected to the outer surface of the annular pipe, each drain pipe extending into the cavity.
[0007] In a further embodiment, the cooling mechanism further includes an annular guide plate fixedly connected to the inner wall of the cavity, wherein the inner diameter of the annular guide plate is larger than the outer diameter of the upper mold cavity of the bottom mold.
[0008] In a further embodiment, the front of the liquid storage tank is connected to a return pipe, and the other end of the return pipe extends to the bottom of the cavity.
[0009] In a further embodiment, the outer surface of the annular tube is fixedly connected with a ring of support rods arranged in a ring, and the bottom end of each support rod is connected to the outer surface of the bottom mold.
[0010] In a further embodiment, a liquid level window is provided on the right side of the liquid storage tank, and an injection pipe with a sealing plug is provided on the upper surface of the liquid storage tank.
[0011] In a further embodiment, the forming structure includes a hanging plate fixedly connected to the upper surface of the base, a hydraulic push rod is mounted on the hanging plate, and a pressing mold is detachably mounted on the telescopic end of the hydraulic push rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This application utilizes a cavity and a cooling mechanism to draw in coolant, which then flows to the inner wall of the cavity to absorb heat. This allows for rapid cooling and molding of the bottom mold and the lens inside the mold, preventing lens deformation during slow cooling and further ensuring the quality of lens molding.
[0014] The annular guide vane can redirect the splashed coolant, allowing it to flow back into the cavity to absorb heat and further ensure effective cooling of the bottom mold and the forming lens. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[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] Please see Figure 1-3 In this utility model, a lens forming device includes a base 1, a bottom mold 2 is provided above the base 1, and a forming structure 3 is provided above the bottom mold 2. The forming structure 3 includes a hanging plate 301 fixedly connected to the upper surface of the base 1. A hydraulic push rod 302 is installed on the hanging plate 301. A pressing mold 303 is detachably installed at the telescopic end of the hydraulic push rod 302. The pressing mold 303 is adapted to the bottom mold 2. When the hydraulic push rod 302 extends, it can push the pressing mold 303 down, and the pressing mold 303 will gradually enter the bottom mold 2, thereby completing the pressing and forming of the lens.
[0022] The bottom mold 2 has a cavity 5 inside. A cooling mechanism 4 for rapidly cooling the bottom mold 2 is provided above the base 1. The cooling mechanism 4 includes a liquid storage tank 401 located above the base 1. A liquid level window 409 is provided on the right side of the liquid storage tank 401. A liquid injection pipe 410 with a sealing plug is provided on the upper surface of the liquid storage tank 401. The operator can observe the remaining amount of coolant inside the liquid storage tank 401 in a timely manner through the liquid level window 409, so that coolant can be added in a timely manner through the liquid injection pipe 410.
[0023] A pump body 402 is installed on the front of the liquid storage tank 401. The output end of the pump body 402 and the front of the liquid storage tank 401 are connected to a liquid extraction pipe 403. The output end of the pump body 402 is connected to an annular pipe 404. The outer surface of the annular pipe 404 is fixedly connected to an annularly arranged support rods 408. The bottom end of each support rod 408 is connected to the outer surface of the bottom mold 2. The support rods 408 can support and reinforce the annular pipe 404, thereby ensuring its stability when transporting coolant. The outer surface of the annular pipe 404 is connected to an annularly arranged drain pipe 405. Each drain pipe 405 extends into the cavity 5. The operation of the pump body 402 can draw coolant from the inside of the liquid storage tank 401. The coolant will then enter the drain pipe 405 along the annular pipe 404. The drain pipe 405 will then spray the coolant onto the inner wall of the cavity 5 inside the bottom mold 2, thereby rapidly cooling the bottom mold 2 and the lens on the inner wall of the bottom mold 2.
[0024] The cooling mechanism 4 also includes an annular guide plate 406 fixedly connected to the inner wall of the cavity 5. The inner diameter of the annular guide plate 406 is larger than the outer diameter of the upper cavity of the bottom mold 2. The annular guide plate 406 can guide the coolant again, allowing the coolant to flow back to the inner wall of the cavity 5, thereby further ensuring the forming effect of the bottom mold 2 and the lens inside the bottom mold 2. The front of the liquid storage tank 401 is connected to a return pipe 407. The other end of the return pipe 407 extends to the bottom of the cavity 5. The return pipe 407 can be used to discharge the coolant after absorbing heat back into the liquid storage tank 401, so that the coolant can be reused.
[0025] The working principle of this application is as follows: After the molding structure 3 completes the molding of the raw material of the bottom mold 2, the pump body 402 is controlled to work. The pump body 402 will draw out the coolant inside the liquid storage tank 401. The coolant will enter the drain pipe 405 along the annular pipe 404 and will be sprayed from the drain pipe 405 onto the inner wall of the cavity 5, thereby cooling the bottom mold 2 and the molding material inside the bottom mold 2. At the same time, part of the sprayed coolant will flow onto the annular guide plate 406 and can flow back to the inner wall of the cavity 5 from the annular guide plate 406, thereby achieving rapid cooling of the formed lens to prevent deformation and ensure product quality.
[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
