Description

Technical Field

[0001] This invention relates to the field of optical glass manufacturing technology, specifically to a molding equipment for manufacturing special optical glass. Background Technology

[0002] Specialty optical glass is mainly driven by the innovation of optical technology and the demand for high-end applications. With the rapid development of optical technology and the expansion of application scenarios, specialty optical glass has characteristics such as high refractive index, low dispersion and high light transmittance. Nowadays, the demand for specialty optical glass in fields such as optical communication, aerospace and medical equipment is surging.

[0003] Patent CN119750890A discloses a molding equipment for optical glass manufacturing, including a manufacturing base. A conveyor plate is rotatably arranged above the manufacturing base, and a rotating shaft is fixed to the lower end of the conveyor plate. The bottom end of the rotating shaft is connected to the output end of an external motor located inside the manufacturing base. Multiple molding seats are arranged on the upper end of the conveyor plate, and a glass molding mold seat is arranged on the upper end of each molding seat. The glass molding mold seat is composed of an upper mold seat and a lower mold seat in an integral manner. A connecting pipe is arranged on the upper end of the upper mold seat. The optical glass molding liquid inside the feeding seat flows into the glass molding mold seat along the connecting pipe and the connecting pipe, realizing the function of automatic feeding of optical glass molding liquid between the glass molding mold seat and the feeding seat. This avoids the problem of manual adjustment and manual feeding required by the operator in the prior art, and brings convenience to the subsequent optical glass molding. However, the above-mentioned device is difficult to achieve the effect of multi-station coordinated work during the molding process, thereby reducing the production efficiency of the device. Therefore, a special optical glass manufacturing molding equipment is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a molding device for manufacturing special optical glass, which addresses the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a molding equipment for manufacturing special optical glass, including a worktable, a shell fixedly connected to the top surface of the worktable, a turntable mechanism rotatably connected to the top surface of the worktable, a hydraulic cylinder fixedly connected to the inner wall of the shell, a demolding mechanism provided on the output end of the hydraulic cylinder, and an air extraction mechanism provided on the surface of the turntable mechanism. The turntable mechanism includes a sleeve rotatably connected to the top surface of the worktable. A rotating disk is rotatably connected to the top surface of the worktable, and a cavity is fixedly connected to the top surface of the rotating disk. A limit block is fixedly connected to the inner wall of the sleeve, and a pawl is hinged to the surface of the limit block by a torsion spring. Gear teeth are provided on the circumferential surface of the rotating disk, and the gear teeth contact the surface of the pawl. The limit block is used to limit the pawl to achieve the effect of unidirectional rotation of the pawl. Before the device is started, the operator places the unformed glass paste inside the cavity. At this time, the hydraulic cylinder is activated, and the extension end of the hydraulic cylinder moves downward. The extension end of the hydraulic cylinder drives the active plate to slide downward on the inner wall of the sleeve. After extrusion molding is completed, the glass paste is placed inside the cavity set on the other side. The multiple cavities fixedly connected to the rotating disk realize the effect of multi-station operation in the device. During the operation of the device, different stations complete different tasks, reducing the workpiece molding time and improving the working efficiency of the device.

[0006] Preferably, the turntable mechanism further includes a drive plate, which is fixedly connected to the output end of the hydraulic cylinder. The circumferential surface of the drive plate is in contact with the inner wall of the sleeve. A guide groove is formed on the circumferential surface of the sleeve, and a protrusion is provided on the circumferential surface of the drive plate. The protrusion is slidably connected to the guide groove formed on the surface of the sleeve. As the drive plate slides downward, the downward movement of the drive plate drives the sleeve to rotate counterclockwise along the guide groove of the sleeve. The rotation of the sleeve drives the limiting block to rotate. At this time, due to the limiting effect of the limiting block, the pawl rotates, and the pawl rotates, driving the cylinder to rotate. The rotating disc drives the cavity to rotate. As the active plate slides upward, it drives the sleeve to rotate clockwise along the guide groove of the sleeve. The rotation of the sleeve drives the limiting block to rotate. At this time, the pawl loses the limiting function of the limiting block. The limiting block drives the pawl to rotate and twists the torsion spring hinged between the limiting block and the pawl. At this time, the rotating disc stops rotating. This process is repeated. The rotation of the rotating disc driven by the active plate realizes the sequentiality of the processing steps of the device, improves the synchronization of movement during the molding process, and ensures that the punch can be accurately pressed into the die during molding, thus guaranteeing the processing quality of the device.

[0007] Preferably, the demolding mechanism includes a top seat, which is fixedly connected to the bottom surface of the active plate. A fixed plate is fixedly connected to the bottom surface of the top seat. The active plate has a movable groove on its surface. A rotating plate is hinged to the inner wall of the active plate by a torsion spring. A driven wheel is rotatably connected to the bottom end of the rotating plate. As the active plate moves downward, it drives the rotating plate to move downward. The rotating plate drives the trigger pin to move downward. When the trigger pin moves to the working range, it contacts and is squeezed by the rotating disk and moves upward relative to the rotating disk and slides on the inner wall of the rotating plate. The upward movement of the trigger pin drives the rotating plate to rotate, and the rotation of the rotating plate drives the driven wheel to rotate.

[0008] Preferably, the inner wall of the fixed plate is slidably connected to a punch via a spring. The punch is positioned on the movement trajectory of the driven wheel. A trigger groove is formed on the surface of the rotating plate, and a trigger post is slidably connected to the inner wall of the trigger groove. The trigger post is positioned on the movement trajectory of the rotating disk. The rotation of the driven wheel drives the punch to move downward. After the glass is formed, the active plate moves upward. At this time, due to the action of the torsion spring hinged between the rotating plate and the active plate, the rotating plate springs back to its original position. The punch, no longer restricted, moves upward under the action of the spring connecting the punch and the active plate. The driven wheel drives the punch to slide on the inner wall of the fixed plate, realizing quick demolding of the device. This prevents the formed glass from sticking to the surface of the punch due to excessive clamping force of the glass paste after cooling, and being carried out by the punch, affecting subsequent processing steps and improving the working efficiency of the device.

[0009] Preferably, the surface of the rotating plate is provided with a demolding groove, the inner wall of the demolding groove is slidably connected with a demolding column, the circumferential surface of the demolding column is slidably connected with the inner wall of the fixed plate, and the circumferential surface of the demolding column is slidably connected with the inner wall of the top seat.

[0010] Preferably, a pressure block is fixedly connected to the bottom surface of the top seat, and a roller is rotatably connected to the side of the pressure block. A trigger block is fixedly connected to the surface of the fixed plate. As the active plate moves upward, the rotating plate rotates and springs back to its original position due to the action of the torsion spring. The rotation of the rotating plate causes the demolding column to slide on the inner wall of the rotating plate and slide downward on the inner wall of the fixed plate. After the device completes processing, the demolding column sliding on the inner wall of the fixed plate is ejected from the surface of the fixed plate, assisting the device in demolding and preventing the glass blank from sticking to the surface of the fixed plate, which would affect the normal operation of subsequent stations and ensure the stability of the device operation.

[0011] Preferably, the air extraction mechanism includes a fixed sleeve, which is fixedly connected to the top surface of the rotating disk. The surface of the fixed sleeve is fixedly connected to the surface of the cavity. A slide bar is slidably connected to the top surface of the rotating disk, and a guide rod is fixedly connected to the surface of the cavity. The inner wall of the slide bar is slidably connected to the circumferential surface of the guide rod by a spring.

[0012] Preferably, an exhaust strip is fixedly connected to the surface of the slide bar, and an exhaust groove is formed on the inner wall of the cavity. The exhaust strip is slidably connected in the exhaust groove, and an inclined block is fixedly connected to the top surface of the exhaust strip. The inclined block is set on the movement trajectory of the roller. When the active plate moves downward, the active plate drives the top seat to move downward, the top seat drives the fixed plate to move downward, the top seat drives the pressure block to move downward, and the pressure block drives the roller to move downward. When the roller moves downward into the working range of the inclined block, the roller squeezes the inclined block and drives the inclined block to move along the inclined surface of the inclined block relative to the inclined block. The cavity moves inward and compresses the spring connecting the slide bar and the cavity. The inclined block moves inward, driving the venting strip to move inward, thus sealing the cavity. When the active plate moves upward, the inclined block loses the limit of the roller. Due to the action of the spring connecting the slide bar and the cavity, the slide bar rebounds and pulls the inclined block outward. The inclined block drives the venting strip outward. The venting strip, driven by the inclined block, moves outward after the glass forming is completed, realizing the venting of the formed material. This prevents gas from being forced into the glass preform during the forming process, which would cause the workpiece to be scrapped, and improves the yield of the device.

[0013] Preferably, the suction mechanism further includes an elastic telescopic rod, which is fixedly connected to the inner wall of the rotating disk. A filler strip is fixedly connected to the telescopic end of the elastic telescopic rod. The filler strip is slidably connected to the inner wall of the rotating disk. A filling hole is opened in the inner wall of the cavity. The filler strip is slidably connected in the filling hole opened in the inner wall of the cavity. The filler strip is set on the movement trajectory of the trigger block. When the active plate moves downward, the active plate drives the top seat to move downward. The top seat drives the fixed plate to move downward. The fixed plate drives the trigger block to move downward. When the trigger block moves into the working range of the filler strip, the trigger block drives the filler strip to slide downward and compress on the inner wall of the cavity. The elastic telescopic rod, moved downward by the sliding filler strip during the molding process, uses the principle of a syringe to draw the glass paste in the cavity to the corner, realizing the effect of assisting glass molding and avoiding the inability to completely fill the cavity due to the poor fluidity of the glass paste, which would affect the final molding effect.

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This special optical glass manufacturing molding equipment achieves multi-station operation through the coordinated operation of sleeves, rotating disks, cavities, limiting blocks, pawls, and active plates. Several cavities fixedly connected on the rotating disk achieve this effect within the device. During operation, different stations complete different tasks, reducing workpiece molding time and improving the device's efficiency. The active plate drives the rotating disk to rotate, ensuring the sequential nature of the processing steps and improving motion synchronization during molding. It also ensures that the punch can be accurately pressed into the die during molding, guaranteeing the processing quality of the device.

[0015] 2. This special optical glass manufacturing molding equipment, through the coordinated operation of the top seat, fixed plate, rotating plate, driven wheel, punch, trigger post, demolding post, pressure block, roller, and trigger block, achieves quick demolding by having the driven wheel drive the punch to slide on the inner wall of the fixed plate. This prevents the molded glass from sticking to the surface of the punch due to excessive clamping force of the glass paste after cooling, and from being carried out by the punch, thus affecting subsequent processing steps and improving the working efficiency of the equipment. The demolding post sliding on the inner wall of the fixed plate is ejected on the surface of the fixed plate after the equipment completes processing, assisting the demolding of the equipment and preventing the glass blank from sticking to the surface of the fixed plate, affecting the normal operation of subsequent stations, and ensuring the stability of the equipment operation.

[0016] 3. This special optical glass manufacturing molding equipment, through the coordinated operation of a fixed sleeve, slide bar, guide rod, inclined block, venting bar, filling bar, and elastic telescopic rod, achieves venting of the formed glass by having the venting bar moved outward after the glass molding is completed by the inclined block. This prevents gas from being forced into the glass preform during the molding process, which would cause the workpiece to be scrapped, thus improving the yield rate of the device. The sliding filling bar moves downward during the molding process and uses the principle of a syringe to draw the glass paste in the cavity to the corner, achieving the effect of assisting glass molding and avoiding the inability to completely fill the cavity due to the poor fluidity of the glass paste, which would affect the final molding effect.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-10 One embodiment of the present invention is: a molding equipment for manufacturing special optical glass, including a worktable 1, a shell 2 fixedly connected to the top surface of the worktable 1, a turntable mechanism 3 rotatably connected to the top surface of the worktable 1, a hydraulic cylinder 4 fixedly connected to the inner wall of the shell 2, a demolding mechanism 5 provided on the output end of the hydraulic cylinder 4, and an air extraction mechanism 6 provided on the surface of the turntable mechanism 3. The turntable mechanism 3 includes a sleeve 31, which is rotatably connected to the top surface of the worktable 1. A turntable 32 is rotatably connected to the top surface of the worktable 1, and a cavity 33 is fixedly connected to the top surface of the turntable 32. A limit block 34 is fixedly connected to the inner wall of the sleeve 31. A pawl 35 is hinged to the surface of the limit block 34 by a torsion spring. Gear teeth are provided on the circumferential surface of the turntable 32, and the gear teeth are in contact with the surface of the pawl 35. The limit block 34 is used to limit the pawl 35 to achieve the effect of unidirectional rotation of the pawl 35. The several cavities 33 fixedly connected to the turntable 32 realize the effect of multi-station operation in the device. Different work is completed by different stations during the operation of the device, which reduces the workpiece forming time and improves the working efficiency of the device.

[0021] The turntable mechanism 3 also includes an active plate 36, which is fixedly connected to the output end of the hydraulic cylinder 4. The circumferential surface of the active plate 36 is in contact with the inner wall of the sleeve 31. A guide groove is provided on the circumferential surface of the sleeve 31, and a protrusion is provided on the circumferential surface of the active plate 36. The protrusion is slidably connected to the guide groove on the surface of the sleeve 31. The active plate 36 drives the turntable 32 to rotate, realizing the sequentiality of the processing steps of the device, improving the motion synchronization during the forming process, and ensuring that the punch 55 can be accurately pressed into the die during forming, thus ensuring the processing quality of the device.

[0022] The demolding mechanism 5 includes a top seat 51, which is fixedly connected to the bottom surface of the active plate 36. A fixed plate 52 is fixedly connected to the bottom surface of the top seat 51. A movable groove is provided on the surface of the active plate 36. A rotating plate 53 is hinged to the inner wall of the active plate 36 by a torsion spring. A driven wheel 54 is rotatably connected to the bottom end of the rotating plate 53.

[0023] A punch 55 is slidably connected to the inner wall of the fixed plate 52 via a spring. The punch 55 is set on the movement trajectory of the driven wheel 54. A trigger groove is opened on the surface of the rotating plate 53. A trigger pin 56 is slidably connected to the inner wall of the trigger groove. The trigger pin 56 is set on the movement trajectory of the rotating disk 32. The driven wheel 54 drives the punch 55 to slide on the inner wall of the fixed plate 52, realizing quick demolding of the device. This prevents the glass from sticking to the surface of the punch 55 due to excessive clamping force after the glass paste cools, and prevents the punch 55 from carrying it out together, thus affecting subsequent processing steps and improving the working efficiency of the device.

[0024] The surface of the rotating plate 53 is provided with a demolding groove, and a demolding column 57 is slidably connected to the inner wall of the demolding groove. The circumferential surface of the demolding column 57 is slidably connected to the inner wall of the fixed plate 52, and the circumferential surface of the demolding column 57 is slidably connected to the inner wall of the top seat 51.

[0025] A pressure block 58 is fixedly connected to the bottom surface of the top seat 51, and a roller 59 is rotatably connected to the side of the pressure block 58. A trigger block 510 is fixedly connected to the surface of the fixed plate 52. The demolding column 57, which slides on the inner wall of the fixed plate 52, is ejected from the surface of the fixed plate 52 after the device has completed processing. This assists in demolding the device, prevents the glass blank from sticking to the surface of the fixed plate 52, and avoids affecting the normal operation of subsequent stations, thus ensuring the stability of the device operation.

[0026] Working principle: Before starting the device, the operator places the unformed glass paste inside the cavity 33. At this time, the hydraulic cylinder 4 is activated, and the telescopic end of the hydraulic cylinder 4 moves downward. The telescopic end of the hydraulic cylinder 4 drives the active plate 36 to slide downward on the inner wall of the sleeve 31. After extrusion molding is completed, the glass paste is placed inside the cavity 33 set on the other side. Several cavities 33 fixedly connected to the rotating disk 32 achieve the effect of multi-station operation in the device. During the operation of the device, different stations complete different tasks, reducing the workpiece molding time and improving the working efficiency of the device. While the active plate 36 slides downward, the downward movement of the active plate 36 drives the sleeve 31 to rotate counterclockwise along the guide groove of the sleeve 31. The rotation of the sleeve 31 drives the limit block 34 to rotate. At this time, the pawl 35 is limited by the limit block 34. The limiting block 34 acts as a stopper, causing the pawl 35 to rotate. The rotation of the pawl 35 causes the rotating disk 32 to rotate, which in turn causes the cavity 33 to rotate. As the active plate 36 slides upward, it causes the sleeve 31 to rotate clockwise along the guide groove of the sleeve 31. The rotation of the sleeve 31 causes the limiting block 34 to rotate. At this time, the pawl 35 loses the limiting function of the limiting block 34. The limiting block 34 causes the pawl 35 to rotate and twists the torsion spring hinged between the limiting block 34 and the pawl 35. At this time, the rotating disk 32 stops rotating. This process is repeated. The rotation of the rotating disk 32 driven by the active plate 36 realizes the sequentiality of the processing steps of the device, improves the synchronization of movement during the molding process, and ensures that the punch 55 can be accurately pressed into the die during molding, thus guaranteeing the processing quality of the device.

[0027] As the active plate 36 moves downward, it drives the rotating plate 53 to move downward. The rotating plate 53 drives the trigger pin 56 to move downward. When the trigger pin 56 reaches the working range, it contacts and is squeezed by the rotating disk 32, moving upward relative to the rotating disk 32 and sliding on the inner wall of the rotating plate 53. The upward movement of the trigger pin 56 drives the rotating plate 53 to rotate. The rotation of the rotating plate 53 drives the driven wheel 54 to rotate. The rotation of the driven wheel 54 drives the punch 55 to move downward. When the glass forming is completed, the active plate 36 moves upward. At this time, due to the action of the torsion spring hinged between the rotating plate 53 and the active plate 36, the rotating plate 53 springs back to its original position. The punch 55 is unrestricted and moves upward by the action of the spring connecting the punch 55 and the active plate 36. Wheel 54 drives punch 55 to slide on the inner wall of fixed plate 52, realizing quick demolding of the device. This prevents the glass from sticking to the surface of punch 55 due to excessive clamping force of the glass paste after cooling, and from being carried out by punch 55, thus affecting subsequent processing steps and improving the working efficiency of the device. While the active plate 36 moves upward, the rotating plate 53 rotates and springs back to its original position due to the action of the torsion spring. The rotation of the rotating plate 53 drives the demolding column 57 to slide on the inner wall of the rotating plate 53 and slide downward on the inner wall of fixed plate 52. The demolding column 57 sliding on the inner wall of fixed plate 52 is ejected on the surface of fixed plate 52 after the device completes processing, assisting the demolding of the device and preventing the glass blank from sticking to the surface of fixed plate 52, affecting the normal operation of subsequent stations and ensuring the stability of the device operation.

[0028] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, the air extraction mechanism 6 includes a fixed sleeve 61, which is fixedly connected to the top surface of the rotating disk 32. The surface of the fixed sleeve 61 is fixedly connected to the surface of the cavity 33. A slide bar 62 is slidably connected to the top surface of the rotating disk 32. A guide rod 63 is fixedly connected to the surface of the cavity 33. The inner wall of the slide bar 62 is slidably connected to the circumferential surface of the guide rod 63 by a spring.

[0029] A venting strip 65 is fixedly connected to the surface of the slide bar 62. A venting groove is provided on the inner wall of the cavity 33. The venting strip 65 is slidably connected in the venting groove. An inclined block 64 is fixedly connected to the top surface of the venting strip 65. The inclined block 64 is set on the movement trajectory of the roller 59. The venting strip 65 is driven by the inclined block 64 to move outward after the glass is formed, which realizes the venting of the formed glass and prevents the gas from being forced into the glass preform during the forming process, which would cause the workpiece to be scrapped, thus improving the yield of the device.

[0030] The vacuum mechanism 6 also includes an elastic telescopic rod 67, which is fixedly connected to the inner wall of the rotating disk 32. A filler strip 66 is fixedly connected to the telescopic end of the elastic telescopic rod 67. The filler strip 66 is slidably connected to the inner wall of the rotating disk 32. A filling hole is opened in the inner wall of the cavity 33. The filler strip 66 is slidably connected in the filling hole opened in the inner wall of the cavity 33. The filler strip 66 is set on the movement trajectory of the trigger block 510. The sliding filler strip 66 moves downward during the molding process and uses the principle of a syringe to draw the glass paste in the cavity 33 to the corner, which realizes the effect of assisting glass molding and avoids the cavity 33 not being completely filled due to the poor fluidity of the glass paste, thus affecting the final molding effect.

[0031] Working principle: As the active plate 36 moves downward, it drives the top seat 51 to move downward, which in turn drives the fixed plate 52 to move downward. The top seat 51 then drives the pressure block 58 to move downward, which in turn drives the roller 59 to move downward. When the roller 59 moves downward into the working range of the inclined block 64, it presses the inclined block 64 and drives it to move inward relative to the cavity 33 along the inclined surface of the inclined block 64, pressing the spring connecting the slide bar 62 and the cavity 33. The inward movement of the inclined block 64 drives the vent strip 65 to move inward, completing the closure of the cavity 33. When the active plate 36 moves upward, the inclined block 64 loses the limit of the roller 59. Due to the action of the spring connecting the slide bar 62 and the cavity 33, the slide bar 62 rebounds and pulls the inclined block 64 outward. The inclined block 64 drives the vent strip 65 outward, thus closing the cavity 33. 4. The exhaust strip 65 moves outward after the glass forming is completed, realizing the exhaust of the formed material and preventing gas from being forced into the glass preform during the forming process, which would cause the workpiece to be scrapped. This improves the yield of the device. At the same time as the active plate 36 moves downward, the active plate 36 drives the top seat 51 to move downward. The top seat 51 drives the fixed plate 52 to move downward. The fixed plate 52 drives the trigger block 510 to move downward. When the trigger block 510 moves into the working range of the filling strip 66, the trigger block 510 drives the filling strip 66 to slide downward and compress on the inner wall of the cavity 33. The elastic telescopic rod 67 moves downward by the sliding filling strip 66 during the forming process. Using the principle of a syringe, the glass paste in the cavity 33 is drawn into the corner, which realizes the effect of assisting glass forming and avoids the poor fluidity of the glass paste from not being able to completely fill the cavity 33, which would affect the final forming effect.
