Description
Technical Field
[0001] This utility model relates to the field of lens technology, and in particular to a multi-process precision forming equipment for optical glass lenses. Background Technology
[0002] Optical glass lenses are transparent elements made of high-purity optical glass, used to focus, diverge, or correct light. Their surfaces are typically spherical or aspherical, altering the path of light through refraction. They are widely used in optical instruments such as cameras, microscopes, and telescopes. Optical glass possesses high light transmittance, low dispersion, and excellent thermal stability, ensuring clear images and accurate colors. Lens types include convex lenses and concave lenses, meeting diverse optical needs.
[0003] However, most optical glass lens forming equipment typically involves hot-melting optical glass into a mold and then cooling it using the upper and lower molds to complete the basic blank shaping. After the lens blank is shaped, it is necessary to manually open the mold and remove the blanks one by one from the shaping groove, which is time-consuming, labor-intensive, and affects the demolding efficiency, thereby reducing the practicality of the equipment.
[0004] Therefore, those skilled in the art have provided a multi-process precision forming equipment for optical glass lenses to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-process precision forming equipment for optical glass lenses. The equipment uses a controller to control a servo motor that drives a rotating shaft. This shaft drives a third bevel gear, which meshes with a fourth bevel gear, causing a second threaded rod to rotate. A second slider, fitted onto the outer wall of the threaded rod, slides upwards along the thread, disengaging the upper mold from the lower mold. Simultaneously, the rotation of the rotating shaft drives the second bevel gear to mesh with a first bevel gear, which in turn rotates the first threaded rod. The two first sliders then slide towards each other on a sliding block, causing the support rod to close and the top block to be lifted upwards at the groove in the lower mold. Finally, in conjunction with the raised upper mold, the lens blank is quickly removed from the mold for easy extraction, improving the demolding efficiency of the lens and thus enhancing the practicality of the equipment.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A multi-process precision molding equipment for optical glass lenses includes a rapid demolding mechanism, a cooling mechanism, and a controller. Cooling mechanisms are provided on both end faces and the center of the rapid demolding mechanism. A controller is provided on one end face of the rapid demolding mechanism. The rapid demolding mechanism includes a slide block, with a first threaded rod rotatably connected to the upper end of the slide block. A first bevel gear is fixedly connected to the center of the outer wall of the first threaded rod. Two first sliders are sleeved on the outer wall of the first threaded rod. A servo motor is provided in the center of one end face of the slide block. A rotating shaft is fixedly connected to the output end of the servo motor. A second bevel gear is fixedly connected to one end of the rotating shaft, and a third bevel gear is fixedly connected to the other end of the rotating shaft. A fourth bevel gear is meshed with one side of the outer wall of the gear. A second threaded rod is fixedly connected to one end of the fourth bevel gear. A second slider is sleeved on the outer wall of the second threaded rod. An upper mold is fixedly connected to one end of the second slider. A support rod is rotatably connected to the middle of the upper end face of each of the two first sliders. A top block is rotatably connected to one end of each of the two support rods. A base is provided in the middle of the upper end face of the slide block. A lower mold is fixedly connected to the upper end of the base. A sliding groove is opened in the middle of the interior of the lower mold. Multiple shaping grooves are opened on one side end face of both the upper and lower molds. A fixed shell is provided on one side end face of the slide block. Guide plates are fixedly connected to both sides of the upper end face of the fixed shell. Multiple material inlets are provided on the upper end face of the upper mold.
[0008] Through the above technical solution, the equipment controls the servo motor to drive the rotating shaft to rotate. The rotating shaft drives the third bevel gear to rotate, and the third bevel gear meshes with the fourth bevel gear to rotate, causing the second threaded rod to rotate. The second slider sleeved on the outer wall of the second threaded rod slides upward with the thread, causing the upper mold to disengage from the lower mold. At the same time, the rotation of the rotating shaft drives the second bevel gear to rotate, causing the second bevel gear to mesh with the first bevel gear to rotate, which in turn causes the first threaded rod to rotate. The two first sliders can then slide towards each other on the slide block and drive the support rod to close together, causing the top block to be pushed upward at the slide groove in the lower mold. Finally, in conjunction with the raised upper mold, the lens blank is quickly separated from the mold for easy removal, improving the demolding efficiency of the lens and thus improving the practicality of the equipment.
[0009] Furthermore, the cooling mechanism includes two first water inlet pipes, each with a plug-in portion fixedly connected to the middle of its lower end face. A first water passage groove is provided in the middle of the interior of the upper mold. Second water inlet pipes are provided on both sides of the lower mold. One end of one of the second water inlet pipes is fixedly connected to a drain pipe, and one end of the other second water inlet pipe is fixedly connected to a water supply pipe. A second water passage groove is provided in the middle of the interior of the lower mold. Sealing gaskets are provided on one side of each of the two first water inlet pipes and the second water inlet pipe.
[0010] Through the above technical solution, the equipment controls the closure of the upper and lower molds via a controller, thereby tightly connecting the second water inlet pipes at both ends of the lower mold and the first water inlet pipes at both ends of the upper mold through the plug and sealing gasket. Subsequently, a water delivery pipe at one end of one of the second water inlet pipes delivers cooling water to the second water channel of the lower mold and the first water channel of the upper mold through an external water pump, enabling the lens blank inside the mold to cool faster. After passing through the two water channels of the mold, the cooling water is finally discharged through another second water inlet pipe and a drain pipe. By merging the upper and lower molds and connecting the water inlet pipes, the overall water cooling of the mold is achieved, improving the convenience of mold cooling and thus enhancing the practicality of the equipment.
[0011] Furthermore, a first threaded rod is rotatably connected to the middle of one side end face of the base, and a rotating shaft is rotatably connected to the middle of one side end face of the base;
[0012] Through the above technical solution, this arrangement enables the first bevel gear on the first threaded rod and the second bevel gear on the rotating shaft to mesh and rotate stably without being affected by external factors.
[0013] Furthermore, a rotating shaft is rotatably connected to the middle of one end face of the fixed shell, and a second threaded rod is rotatably connected to the middle of one end face of the fixed shell.
[0014] Through the above technical solution, this arrangement enables the third bevel gear on the rotating shaft and the fourth bevel gear on the second threaded rod to mesh and rotate stably without being affected by external factors.
[0015] Furthermore, a second slider is slidably connected to one side of the outer wall of the two guide plates, the paths of the multiple material inlets do not intersect with the path of the first water passage, and a square cover for sealing is provided at the upper end of the multiple material inlets.
[0016] Through the above technical solution, the second slider can slide stably on the guide plate without deviating, the material inlet is used to inject the hot-melted optical glass, the non-intersecting paths ensure that the existence of the material inlet will not affect the subsequent cooling, and the square cover for sealing can make the mold more sealed.
[0017] Furthermore, the two insertion parts are slidably connected to one end opening of the second water inlet pipe;
[0018] The above technical solution enables the second water inlet pipe to be smoothly connected to the first water inlet pipe when the upper and lower molds are combined.
[0019] Furthermore, both ends of the first water passage are connected to the first water inlet pipe, and both ends of the second water passage are connected to the second water inlet pipe.
[0020] Through the above technical solution, this setup enables cooling water to be delivered to the upper and lower molds in a timely manner.
[0021] Furthermore, the water supply pipe is connected to an external water pump for supplying water into the water tank of the mold for cooling.
[0022] The above technical solution enables the external water source to be introduced into the mold in a timely manner, facilitating the entire cooling process.

The second slider 111, fitted on the outer wall of the threaded rod 110, slides upward along the thread, causing the upper mold 112 to disengage from the lower mold 116. At the same time, the rotation of the rotating shaft 106 drives the second bevel gear 107 to rotate, causing the second bevel gear 107 to mesh with the first bevel gear 103 and rotate, which in turn causes the first threaded rod 102 to rotate.

Finally, in conjunction with the raised upper mold 112, the lens blank is quickly removed from the mold for easy removal, improving the demolding efficiency of the lens and thus improving the practicality of the equipment.
[0036] Reference Figure 3-5The cooling mechanism 2 includes two first water inlet pipes 201, each with a fixed connector 202 at the center of its lower end face. A first water passage groove 203 is formed in the center of the upper mold 112. Second water inlet pipes 204 are provided on both sides of the lower mold 116. One end of one second water inlet pipe 204 is fixedly connected to a drain pipe 205, and the other end is fixedly connected to a water supply pipe 206.

Sealing gaskets 208 are provided on one side of each of the two first water inlet pipes 201 and the second water inlet pipe 204. The device controls the upper mold 112 and lower mold 116 to close via a controller 3, thereby causing the lower mold 116 to be closed at both ends. The second water inlet pipe 204 and the first water inlet pipes 201 at both ends of the upper mold 112 are tightly connected together through the plug part 202 and the sealing gasket 208.

After passing through the two water passages of the mold, the cooling water is finally discharged through another second water inlet pipe 204 and the drain pipe 205. By combining the upper mold 112 and the lower mold 116 and connecting the water pipes, the overall water cooling of the mold is realized, which improves the convenience of mold cooling and thus improves the practicality of the equipment.
[0037] A first threaded rod 102 is rotatably connected to the middle of one side end face of the base 115, and a rotating shaft 106 is rotatably connected to the middle of one side end face of the base 115. This arrangement enables the first bevel gear 103 on the first threaded rod 102 and the second bevel gear 107 on the rotating shaft 106 to mesh and rotate stably without being affected by external factors.
[0038] A rotating shaft 106 is rotatably connected to the middle of one end face of the fixed housing 119, and a second threaded rod 110 is rotatably connected to the middle of one end face of the fixed housing 119. This arrangement enables the third bevel gear 108 on the rotating shaft 106 and the fourth bevel gear 109 on the second threaded rod 110 to mesh and rotate stably without being affected by external factors.
[0039] The outer walls of the two guide plates 120 are slidably connected to the second slider 111. The paths of the multiple material inlets 121 do not intersect with the path of the first water channel 203. Each of the multiple material inlets 121 is provided with a square cover for sealing.

The third bevel gear 108 meshes with the fourth bevel gear 109, causing the second threaded rod 110 to rotate. The second slider 111, which is sleeved on the outer wall of the second threaded rod 110, slides upward with the thread, causing the upper mold 112 to disengage from the lower mold 116. At the same time, the rotation of the rotating shaft 106 drives the second bevel gear 107 to rotate, causing the second bevel gear 107 to mesh with the first bevel gear 103, which in turn causes the first threaded rod 102 to rotate. The two first sliders 104 can then slide towards each other on the slide block 104, driving the support rod 113 to close together, causing the top block 114 to be pushed upward at the groove 117 in the lower mold 116. Finally, in conjunction with the raised upper mold 112, the lens blank is quickly separated from the mold for easy removal. The equipment controls the upper mold 112 and the lower mold 116 to close through the controller 3, so that the second water inlet pipes 204 set at both ends of the lower mold 116 and the first water inlet pipes 201 set at both ends of the upper mold 112 are tightly connected together through the plug part 202 and the sealing gasket 208. Then, the water supply pipe 206 set at one end of one of the second water inlet pipes 204 delivers cooling water into the second water passage 207 of the lower mold 116 and the first water passage 203 of the upper mold 112 through an external water pump, so that the lens blank in the mold can be cooled faster. After passing through the two water passages of the mold, the cooling water is finally discharged through another second water inlet pipe 204 and the drain pipe 205.
