Description

Technical Field

[0001] This utility model belongs to the field of ceramic seal processing technology, and specifically relates to a stamping equipment for ceramic seals. Background Technology

[0002] Due to its extremely high hardness, excellent wear resistance, and chemical stability, ceramic materials are widely used in fluid mechanical sealing applications in many fields such as chemical engineering, machinery, and environmental protection. They have become key components to ensure the efficient and stable operation of equipment. In the processing of wear-resistant ceramic seals, one of the core processes is to stamp a seal blank from a whole ceramic blank, and then perform subsequent finishing to obtain the finished product. This processing method has become a commonly used processing solution in the industry because of its relatively straightforward operation process and suitability for mass production needs. To optimize the forming and processing effects of ceramic products, targeted technological research and development has been carried out in related fields. Silicon carbide is also a type of ceramic product, for example, application number 201721755489.9 A Chinese utility model patent discloses an isobaric molding device for silicon carbide products. Through the design of the molding structure, it solves to some extent the technical problem of cumbersome removal of finished ceramic products in traditional molding equipment, providing a new path for the molding and processing of ceramic products. However, this existing technology still has significant shortcomings in practical application: First, the device operation process is cumbersome, requiring a high level of operator proficiency, making it difficult to meet the needs of high-efficiency production; second, the control of the force distribution on the blank during the stamping process is not precise enough, leading to problems such as dimensional deviations and insufficient surface flatness in the molded ceramic sealing blanks, resulting in poor stamping quality; third, even if the problem of difficult removal of finished products is solved, the removal process still lacks efficiency, resulting in low removal efficiency and restricting the overall production cycle; fourth, the device does not have a rapid automated demolding mechanism, relying on manual assisted demolding or traditional mechanical demolding methods, which not only further reduces production efficiency but also easily causes damage to the ceramic sealing blanks due to improper demolding operations, affecting the product qualification rate. In summary, although existing stamping equipment for ceramic seals has made improvements in some aspects, it still has shortcomings in core performance areas such as ease of operation, stamping quality control, extraction efficiency, and automated demolding. These shortcomings make it difficult to meet the current industry's demand for efficient and high-precision processing of wear-resistant ceramic seals. Therefore, it is urgent to develop a processing equipment and process that can overcome the above-mentioned defects in order to improve the processing quality and production efficiency of ceramic seals. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a stamping equipment for ceramic seals to solve the problems raised in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A stamping device for ceramic seals includes a base, with support legs fixedly installed at the four corners of the top of the base.

The flexible conveyor belts can receive and discharge the molded and demolded products. In addition, the flexible conveyor belts are soft and can prevent fragile ceramic seals from falling and breaking, thus enabling rapid and automated production. The stamping mechanism is used to assist in providing stamping power and acting on the bearing mechanism to realize the stamping process of the product. The stamping mechanism includes side seats, which are welded and installed on the middle of both sides of the stamping table. A mounting frame is fixedly installed on the top of the side seats. A base is integrally formed in the middle of the top of the mounting frame. A hydraulic cylinder is installed on the inner side of the base by screws. A stamping and demolding module is fixedly installed at the bottom of the hydraulic cylinder. A control base is provided on one side of the mounting frame. A PLC controller is installed on the inner side of the control base. The hydraulic cylinder is used to provide pressure to the stamping and demolding module to make it complete the stamping work. At the same time, during the hydraulic cylinder reset, the stamping and demolding module can also complete the demolding work.

[0005] As a preferred technical solution, the supporting mechanism includes an annular seat and a pusher module. The annular seat is bolted to the middle of the side of the stamping table near the stamping mechanism. The top of the annular seat is evenly spaced in a ring and a lower forming mold is installed by screws. The pusher module is movably disposed on the outside of the annular seat. The pusher module is used to flatten and form the material in the lower forming mold and then remove it from the top of the lower forming mold to achieve automatic demolding.

[0006] As a preferred technical solution, the stamping and demolding module includes a pressure rod, which is fixedly connected to the bottom output end of a hydraulic cylinder. An upper template is fixedly installed at the bottom of the pressure rod. An upper stamping die is installed at the bottom of the upper template in a ring with equal spacing and bolts. The positions of the upper stamping die and the lower forming die correspond one-to-one. A demolding component is fixedly installed at the bottom of the pressure rod. Each demolding end of the demolding component passes through the lower forming die to assist in demolding. The hydraulic cylinder can drive the upper template to drive the upper stamping die to insert into the lower forming die to complete the stamping process. During use, a pressure sensor is appropriately provided at the bottom output end of the hydraulic cylinder to detect the stamping pressure.

[0007] As a preferred technical solution, the ejector module includes an annular groove, a discharge groove, and a driving device. The annular groove is located on the top of the stamping table and outside the annular seat. A slip ring is slidably connected inside the annular groove. A demolding push plate is fixedly connected to the top of the slip ring in a ring with equal spacing. The demolding push plate is located above one side of each lower forming mold. The discharge groove is located on the top of the annular seat in a ring with equal spacing. The bottom output end of the discharge groove passes through the annular seat and the stamping table. The discharge grooves are respectively located on one side of each lower forming mold. By driving the slip ring to rotate inside the annular groove through the driving device, the demolding push plate can be moved along the direction of the annular groove. At this time, the ceramic sealing product ejected by the demolding component can be pushed from the demolding end of the demolding component into the discharge groove for discharge. During use, a displacement sensor is provided at the annular seat to assist in controlling the rotation of the slip ring.

[0008] As a preferred technical solution, a reserved groove is provided in the middle of the top of the stamping table. The reserved groove is located in the middle of the inner side of the annular seat, and the bottom end of the demolding component passes through the reserved groove.

[0009] As a preferred technical solution, the demolding assembly includes a connecting rod, which is integrally formed at the bottom end of the pressure rod. The bottom end of the connecting rod passes through the stamping table via a pre-reserved slot. A base frame is fixedly installed at the bottom end of the connecting rod. Demolding ejector pins are fixedly connected at equal intervals to the top of the base frame. The positions of the demolding ejector pins correspond one-to-one with each lower forming mold. The top end of the demolding ejector pin passes through the lower forming mold. The demolding ejector pin is slidably disposed inside the lower forming mold. A demolding support plate is fixedly installed on the top of the demolding ejector pin. The demolding support plate can rise and fall with the demolding ejector pin within the forming mold. When the hydraulic cylinder pushes the upper stamping mold downward, it will simultaneously drive the connecting rod and its bottom demolding ejector pins and demolding support plate downward. The upper stamping die applies pressure to form the product. The stroke of the hydraulic cylinder pushing the upper stamping die to complete the forming is exactly set to the sliding stroke of the demolding support plate, ensuring that the two do not conflict. The demolding support plate is located at the bottom to receive the product. After stamping is completed, the hydraulic cylinder resets. At this time, the hydraulic cylinder will synchronously drive the connecting rod to move upward. The upward movement of the connecting rod can pull the demolding support plate to move upward and push the product out of the lower forming die. At this time, in conjunction with the drive device, the drive slip ring rotates, which can drive the demolding push plate to push the product into the discharge groove for discharge, realizing automatic demolding and material discharge. During specific applications, a corresponding buffer spring can be set at the bottom of the connecting rod as needed. The buffer spring is connected to the bottom frame to reserve extension space for the base frame, thereby ensuring the operation of the demolding support plate and the upper stamping die.

[0010] As a preferred technical solution, the driving device includes a circular seat and an arc-shaped rack.

The arc-shaped rack is welded and installed on the side of the slip ring near the circular seat. A drive motor is bolted to the bottom of the circular seat. A gear is rotatably connected to the top of the circular seat. The bottom of the gear is connected to the output end of the drive motor through a coupling. The gear and the arc-shaped rack are meshed. During application, the driving device is used to drive the gear to drive the arc-shaped rack to drive the slip ring to reciprocate by rotating the drive motor in both forward and reverse directions. This pushes the formed product into the discharge groove and then automatically resets it. The gear and the arc-shaped rack are provided with a protective shell to assist in dust protection, prevent lubricant failure, and avoid harm to the human body.

[0011] In summary, the present invention has the following main advantages: Firstly, during the application of this technical solution, by setting up an automatic demolding linkage mechanism, an integrated stamping and demolding power mechanism, and an automated control mechanism, the stamping and demolding actions can be synchronized during use. No manual intervention is required for demolding, and the demolding process is precise and controllable. At the same time, with the forming positioning and pressure stabilization mechanism, damage caused by uneven force on the product during demolding is avoided, thus achieving the core effect of rapid automated demolding. This solves the problem of lack of rapid automated demolding and reliance on manual assistance in existing technologies, greatly reducing the time loss in the demolding process, reducing the impact of human operation on the product, and allowing the demolding process to be seamlessly connected with the stamping process, making it more suitable for the continuous operation needs of mass production. Secondly, during the application of this technical solution, by setting up a multi-station synchronous pushing mechanism and a flexible conveying mechanism, it is possible to quickly and synchronously push products from multiple stations to the discharge stage after automatic demolding. The demolding and pushing actions are coordinated and linked, and the flexible conveying structure avoids the situation of products falling and being damaged after demolding. In conjunction with the protective mechanism, it ensures the stable operation of key demolding components, thereby enhancing the practicality and efficiency of automatic demolding. It solves the problems of cumbersome product removal and low automation in existing technologies, improves product qualification rate and demolding continuity, and realizes the full-process automated connection from demolding to discharge, further amplifying the role of automatic demolding in improving overall production efficiency.

Detailed Implementation

[0014] Example refer to Figures 1 to 4 This embodiment of a ceramic seal stamping equipment includes a base 1, with support legs 2 fixedly installed at the four corners of the top of the base 1, a stamping table 3 fixedly installed on the top of the support legs 2, a stamping mechanism 6 fixedly installed on the top of the stamping table 3, a bearing mechanism 5 fixedly installed in the middle of the stamping table 3, the stamping mechanism 6 being located on the outside of the bearing mechanism 5, and its stamping end being located directly above the bearing mechanism 5, and conveyor belt mounting frames 4 being fixedly installed on both sides of the bottom of the stamping table 3. The conveyor belt mounting frames 4 are used to install flexible conveyor belts. The flexible conveyor belt can receive and discharge the molded and demolded products, and its softness can prevent fragile ceramic seals from falling and breaking, thus achieving rapid and automated production and processing. The stamping mechanism 6 is used to assist in providing stamping power and acting on the bearing mechanism 5 to realize product stamping processing. The stamping mechanism 6 includes side seats 61, which are welded to the middle of both sides of the stamping table 3. A support frame 62 is fixedly installed on the top of the side seats 61. A base 63 is integrally formed in the middle of the top of the support frame 62. A hydraulic cylinder 64 is installed on the inner side of the base 63 by screws. A stamping and demolding module 65 is fixedly installed on the bottom of the hydraulic cylinder 64. A control base 66 is provided on one side of the support frame 62. A PLC controller 67 is installed on the inner side of the control base 66. The hydraulic cylinder 64 is used to provide pressure to the stamping and demolding module 65 to make it complete the stamping work. At the same time, during the reset of the hydraulic cylinder 64, the stamping and demolding module 65 can also complete the demolding work. During the application of this device, its... By configuring a base 1, support legs 2, a stamping table 3, a stamping mechanism 6, a bearing mechanism 5, a conveyor belt mounting frame 4, and a flexible conveyor belt, the base 1 and support legs 2 provide stable support for the entire equipment during use. The stamping table 3 provides the mounting foundation for each working component. After the operator places the ceramic blank on the bearing mechanism 5, the stamping mechanism 6 begins operation. The side seat 61 and the mounting frame 62 provide mounting support for the base 63 and the hydraulic cylinder 64. After the hydraulic cylinder 64 inside the base 63 is activated, it generates stamping power, pushing the stamping and demolding module 65 downwards onto the blank on the bearing mechanism 5, realizing the stamping forming process of the ceramic seal. The PLC inside the base frame 66 controls the process. The controller is used to regulate the operating status of the hydraulic cylinder 64 to ensure the precise execution of the stamping process. After stamping is completed, the hydraulic cylinder 64 enters the reset stage. At this time, the stamping and demolding module 65 simultaneously performs demolding work, separating the formed ceramic seal from the bearing mechanism 5. The demolded product is then discharged and falls onto the flexible conveyor belt installed on the conveyor belt mounting brackets 4 on both sides of the bottom of the stamping table 3. The flexible conveyor belt can not only quickly receive and transport the discharged products to realize automated production processing, but also effectively avoid the fragile ceramic seal from breaking during the fall due to its softness. At the same time, the stamping mechanism 6 completes the stamping and demolding power supply simultaneously through the hydraulic cylinder 64, eliminating the need for an additional independent demolding power component. This simplifies the equipment structure and improves processing efficiency. The precise control of the PLC controller ensures the coordination of the stamping and demolding actions, making the entire processing flow smooth and continuous. This reduces the need for manual intervention and lowers the risk of product breakage, further adapting to the demand for efficient and stable production.

[0015] refer to Figure 1 and Figure 3The supporting mechanism 5 includes an annular seat 51 and a pusher module 52. The annular seat 51 is bolted to the center of the stamping table 3 near the stamping mechanism 6. The top of the annular seat 51 is evenly spaced in a ring and screwed to install the lower forming mold 53. The pusher module 52 is movably disposed on the outside of the annular seat 51. The pusher module 52 is used to flatten and form the lower forming mold 53 and then remove it from the top of the lower forming mold 53 after demolding to achieve automatic demolding. The stamping and demolding module 65 includes a pressure rod 651, which is fixedly connected to the bottom output end of the hydraulic cylinder 64. The bottom of the pressure rod 651 is fixedly installed with an upper template 652. The bottom of the upper template 652 is evenly spaced in a ring and bolted to install the upper stamping mold. The upper stamping die 653 and the lower forming die 53 are positioned in a one-to-one correspondence. A demolding assembly 654 is fixedly installed at the bottom of the pressure rod 651. Each demolding end of the demolding assembly 654 passes through the lower forming die 53 to assist in demolding. The hydraulic cylinder 64 pushes and drives the upper template 652 to drive the upper stamping die 653 into the lower forming die 53 to complete the stamping process. During use, a pressure sensor is appropriately installed at the bottom output end of the hydraulic cylinder 64 to detect the stamping pressure. During the application of this device, by setting up the bearing mechanism 5, the stamping and demolding module 65, and the pressure sensor, the ceramic blank can be placed in the lower forming die 53 of the bearing mechanism 5 first, and then the hydraulic cylinder 64 is started and pushed. The pressure rod 651 moves downward, causing the upper template 652 and the bottom upper stamping die 653 to move synchronously. Since the upper stamping die 653 and the lower forming die 53 are positioned in a one-to-one correspondence, the upper stamping die 653 precisely inserts into the lower forming die 53, applying pressure to the blank to complete the stamping process. During this process, the pressure sensor at the bottom output end of the hydraulic cylinder 64 monitors the stamping pressure in real time to ensure that the stamping pressure meets the processing requirements and avoids product forming defects due to improper pressure. After stamping is completed, the demolding assembly 654 begins to function, with each demolding end penetrating the lower forming die 53 to assist in demolding, removing the formed product from the lower forming die 53. After demolding is complete, the annular seat... The pusher module 52 on the outside of 51 will be activated, flattening and removing the demolded product from the top of the lower forming mold 53, further realizing automatic demolding without manual intervention. This design allows the stamping and demolding processes to be seamlessly connected. The precise correspondence between the upper stamping mold 653 and the lower forming mold 53 ensures the product forming accuracy. The application of pressure sensors improves the controllability of the stamping process. The cooperation between the pusher module 52 and the demolding component 654 completely realizes automatic demolding, reducing manual operation steps. This not only reduces the risk of product damage due to human error but also speeds up the processing pace, making the entire production process more efficient and stable. It also avoids the problem of low efficiency in manual demolding affecting the overall production progress.

[0016] refer to Figure 2 and Figure 4The ejector module 52 includes an annular groove 521, a discharge groove 522, and a drive device 523. The annular groove 521 is located on the top of the stamping table 3 and outside the annular seat 51. A sliding ring 524 is slidably connected inside the annular groove 521. The top of the sliding ring 524 is fixedly connected with a demolding ejector plate 525 arranged in a ring at equal intervals. The demolding ejector plate 525 is located above one side of each lower forming mold 53. The discharge groove 522 is arranged in a ring at equal intervals on the top of the annular seat 51. The bottom output end of the discharge groove 522 passes through the annular seat 51 and the stamping table 3. The discharge grooves 522 are respectively located on one side of each lower forming mold 53. The drive device 523 drives the sliding ring 524 to rotate inside the annular groove 521, which in turn drives the demolding ejector plate 525 along the ring. The ceramic sealing component ejected by the demolding assembly 654 moves in the direction of the groove 521, thus pushing it from the demolding end of the demolding assembly 654 into the discharge groove 522 for discharge. During use, a displacement sensor is provided at the annular seat 51 to assist in controlling the rotation of the slip ring 524. A reserved groove 526 is provided in the middle of the top of the stamping table 3. The reserved groove 526 is located in the middle of the inner side of the annular seat 51. The bottom end of the demolding assembly 654 passes through the reserved groove 526. During the application of this device, by setting up the pusher module 52, the reserved groove 526, and the displacement sensor, when the demolding assembly 654 ejects the ceramic sealing component from the lower forming mold 53, the drive device 523 will start to operate, driving the slip ring 524 to rotate inside the annular groove 521. The ejector plate 525 at the top of ring 524 moves along the annular groove 521 with the slip ring 524. Since the ejector plate 525 is located above one side of each lower forming mold 53, it can push the product ejected by the ejector assembly 654 from the ejector end to the discharge groove 522 during the movement. The bottom output end of the discharge groove 522 passes through the annular seat 51 and the stamping table 3. After the product enters the discharge groove 522, it will be discharged along the groove. At the same time, the displacement sensor at the annular seat 51 will monitor the rotation of the slip ring 524 in real time, assisting in controlling the rotation angle and speed of the slip ring 524 to ensure that the ejector plate 525 can accurately push the product without colliding with other parts. In addition, the bottom end of the ejector assembly 654 passes through the reserved groove 526 in the middle of the top of the stamping table 3. The 6 provides the necessary space for the movement of the demolding assembly 654, preventing it from being obstructed during operation. Throughout the process, the pusher module 52 automatically pushes the product through the cooperation of the slip ring 524 and the demolding push plate 525. The discharge groove 522 provides a fixed channel for product discharge. The application of displacement sensors ensures the accuracy of the pushing action, and the reserved groove 526 ensures the normal operation of the demolding assembly 654. These structures work together to allow the demolded product to be discharged quickly and orderly without the need for manual product transfer. This not only reduces manual labor but also avoids product damage that may be caused by manual operation. At the same time, precise pushing control also reduces the probability of the product getting stuck in the equipment, further improving the smoothness and efficiency of the processing flow.This makes the material unloading process after automatic demolding more stable and reliable.

[0017] refer to Figures 2-3The demolding assembly 654 includes a connecting rod 6541, which is integrally formed at the bottom end of the pressure rod 651. The bottom end of the connecting rod 6541 passes through the stamping table 3 through a pre-reserved slot 526. A base frame 6542 is fixedly installed at the bottom end of the connecting rod 6541. Demolding ejector rods 6543 are fixedly connected at equal intervals to the top of the base frame 6542. The positions of the demolding ejector rods 6543 correspond one-to-one with each of the lower forming molds 53. The top end of the demolding ejector rod 6543 passes through the lower forming mold 53. The demolding ejector rod 6543 is slidably set inside the lower forming mold 53. A demolding support plate 6544 is fixedly installed on the top of the demolding ejector rod 6543. The demolding support plate 6544 can rise and fall with the demolding ejector rod 6543 within the forming mold. The hydraulic cylinder 64 pushes... When the upper stamping die 653 moves downward, it simultaneously drives the connecting rod 6541 and its bottom ejector pin 6543 and ejector plate 6544 downward. At this time, the upper stamping die 653 applies pressure to form the product. The stroke of the hydraulic cylinder 64 pushing the upper stamping die 653 after forming is exactly set to the sliding stroke of the ejector plate 6544, ensuring that the two do not conflict. The ejector plate 6544 is located at the bottom to receive the product. After stamping is completed, the hydraulic cylinder 64 resets. At this time, the hydraulic cylinder 64 simultaneously drives the connecting rod 6541 upward. The upward movement of the connecting rod 6541 can pull the ejector plate 6544 upward to push the product out of the lower forming die 53. At this time, in conjunction with the drive device 523 driving the slip ring 524 to rotate, it can drive the ejector plate 525 to push the product into the discharge plate. Automatic demolding and material discharge are achieved by discharging material inside the groove 522. During specific applications, a corresponding buffer spring can be installed at the bottom of the connecting rod 6541 as needed. The buffer spring is connected to the base frame 6542 at the bottom to provide extension space for the base frame 6542, thereby ensuring the operation of the demolding support plate 6544 and the upper stamping die 653. The drive device 523 includes a round seat 5231 and an arc-shaped rack 5232. The round seat 5231 is integrally formed and located in the middle of the rear side of the stamping table 3. The arc-shaped rack 5232 is welded and installed on the side of the slip ring 524 near the round seat 5231. A drive motor 5233 is bolted to the bottom of the round seat 5231. A gear 5234 is rotatably connected to the top of the round seat 5231. The bottom of the gear 5234 is connected to the drive motor via a coupling. The output end of the motor 5233 is connected, and the gear 5234 and the arc-shaped rack 5232 are meshed. The drive device 523 is used to drive the motor 5233 to rotate in both forward and reverse directions during application, which causes the gear 5234 to drive the arc-shaped rack 5232 to drive the slip ring 524 to rotate reciprocally, thereby pushing the formed product into the discharge groove 522 and then automatically resetting. The gear 5234 and the arc-shaped rack 5232 are provided with a protective shell for dust protection, preventing lubricant failure and avoiding harm to the human body. During the application of this device, the demolding component 654, the drive device 523, and the protective shell ensure that when the hydraulic cylinder 64 pushes the upper stamping die 653 down for stamping operation,Simultaneously, the connecting rod 6541 at the bottom of the pressure rod 651 moves downward. After passing through the reserved slot 526, the connecting rod 6541 drives the bottom frame 6542, the demolding ejector rod 6543, and the demolding support plate 6544 to move downward together. At this time, the demolding support plate 6544 is in the bottom receiving state in the forming mold. The upper stamping mold 653 applies pressure to form the blank, and the stroke of the hydraulic cylinder 64 pushing the upper stamping mold 653 after forming matches the sliding stroke of the demolding support plate 6544 to ensure that the two actions do not conflict. When the stamping is completed and the hydraulic cylinder 64 resets, it will simultaneously drive the connecting rod 6541 to move upward. The moving base frame 6542 and the demolding ejector pin 6543 move upwards, and the demolding receiving plate 6544 rises with the demolding ejector pin 6543 inside the forming mold, pushing the formed product out of the forming mold 53. At this time, the drive device 523 starts to operate, and the drive motor 5233 at the bottom of the round seat 5231 rotates in the forward direction, driving the gear 5234 at the top of the round seat 5231 to rotate through the coupling. Since the gear 5234 is meshed with the arc-shaped rack 5232 on one side of the slip ring 524, the rotation of the gear 5234 causes the arc-shaped rack 5232 to drive the slip ring 524 to rotate in the annular groove 521, and the demolding push plate 525 at the top of the slip ring 524 moves accordingly. The demolding plate 525 pushes the product ejected by the demolding receiving plate 6544 into the discharge groove 522 for discharge, achieving automatic demolding and material discharge. After the product is discharged, the drive motor 5233 rotates in the reverse direction, driving the gear 5234, the arc-shaped rack 5232, and the slip ring 524 to move in the opposite direction. The demolding push plate 525 resets to await the next operation. In specific applications, a buffer spring can be set at the bottom of the connecting rod 6541 as needed. The buffer spring is connected to the base frame 6542, which can reserve extension space for the base frame 6542 to ensure that the operation of the demolding receiving plate 6544 and the upper stamping die 653 is not affected. At the same time, the outer shell of the gear 5234 and the arc-shaped rack 5232 is covered. The casing provides dust protection, prevents lubricant failure, and protects against injury from moving parts. Throughout the process, the demolding assembly 654 automatically ejects the product through synchronized movement with the hydraulic cylinder 64. The drive device 523, with the assistance of a motor, gears 5234, and an arc-shaped rack 5232, automatically pushes and resets the product. The buffer spring can flexibly adapt to different processing requirements, while the casing ensures safe operation and extends component lifespan. No manual intervention is required in the demolding and pushing process, improving efficiency and reducing potential product damage from manual operation, making the automatic demolding and material handling process more stable and safer.

[0018] Operating principle and advantages: This device relies on the base 1 and support legs 2 for stable support. The stamping table 3 is fixedly installed on the top of the support legs 2, providing a mounting base for each component. The side seats 61 are fixed on both sides of the stamping table 3. The mounting frame 62 on its top and the base 63 on the top of the mounting frame 62 provide a mounting carrier for the hydraulic cylinder 64. The PLC controller in the control frame 66 completes the setting of various operating parameters. The pressure sensor establishes a signal connection with the PLC controller to provide feedback on the stamping pressure. The displacement sensor is installed at the ring seat 51 to monitor the position of the slip ring 524. The buffer spring connects the base frame 6542 and the connecting rod 6541 to reserve the extension space of the base frame 6542 and avoid the demolding support plate 6544 from causing action conflict with the upper stamping die 653. The flexible conveyor belt is installed through the conveyor belt mounting frame 4 and is located below the discharge chute 522. The operator places the ceramic blanks one by one on the top of the demolding support plate 6544 inside the lower forming die 53 to complete the preparation work before operation.

[0019] Once preparations are complete, the PLC controller sends a start signal, and the hydraulic cylinder 64 begins operation. Its output pushes the pressure rod 651 downward, causing the upper template 652 and the bottom upper stamping die 653 to move downward synchronously. Simultaneously, the connecting rod 6541 at the bottom of the pressure rod 651 moves downward and passes through the reserved slot 526, thereby causing the base frame 6542 and the demolding ejector rod 6543 and demolding support plate 6544 on the base frame 6542 to move downward together. The upper stamping die 653 gradually approaches and enters the lower forming die 53, applying pressure to the blank to complete the stamping operation. During this process, the pressure sensor detects the stamping pressure output by the hydraulic cylinder 64 in real time and transmits the data to the PLC controller to ensure that the pressure during the stamping process meets the set requirements. The upper stamping die 653 and the lower forming die 53 cooperate precisely, and the demolding support plate 6544 keeps the blank position stable, preventing the blank from shifting during the stamping process.

[0020] After the stamping process is completed, the PLC controller sends a reset signal. The hydraulic cylinder 64 resets and moves the pressure rod 651, upper template 652, and upper stamping die 653 upwards, disengaging them from the lower forming die 53. Simultaneously, the connecting rod 6541 moves upwards with the pressure rod 651, driving the demolding ejector rod 6543 and demolding support plate 6544 upwards via the base frame 6542. The demolding support plate 6544 pushes the formed ceramic seal out of the lower forming die 53, achieving initial demolding. Subsequently, the PLC... The controller sends a running signal to the drive unit 523. The circular seat 5231 in the drive unit 523 is fixed to the middle of the rear side of the stamping table 3, providing mounting support for the drive motor 5233 and the gear 5234. The drive motor 5233 starts and rotates in the forward direction, driving the gear 5234 to rotate through the coupling. Since the gear 5234 meshes with the arc-shaped rack 5232 on one side of the slip ring 524, the rotation of the gear 5234 drives the slip ring 524 to slide in the annular groove 521 in a set direction. The demolding push plate 525 on the top of the slip ring 524 moves synchronously with the slip ring 524, passing over the side of the lower forming mold 53, and pushing the ceramic seal ejected by the demolding support plate 6544 towards the discharge groove 522.

[0021] After the ceramic seal enters the discharge chute 522, it falls along the chute onto the flexible conveyor belt below. The flexible conveyor belt starts and transports the product to the outside of the equipment, completing the product discharge operation. After the product is discharged, the PLC controller controls the drive motor 5233 to rotate in the reverse direction. The gear 5234 drives the arc-shaped rack 5232 to drive the slip ring 524 to slide in the reverse direction. The demolding push plate 525 returns to its initial position with the slip ring 524, waiting for the next work cycle. The housing protects the gear 5234 and the arc-shaped rack 5232 from dust adhesion and lubrication failure, while also preventing injury to the operator from moving parts. The displacement sensor transmits the position data of the slip ring 524 to the PLC controller in real time to ensure accurate reset of the slip ring 524. The reserved slot 526 provides movement space for the connecting rod 6541, ensuring the normal lifting and lowering of the demolding assembly 654. This device is equipped with a PLC. The controller automates all actions, requiring only the operator to place the blank and set parameters, simplifying the operation and solving the inconvenience of existing technologies. The application of pressure sensors ensures the stability of stamping pressure. The precise matching of the upper stamping die 653 and the lower forming die 53, along with the stable support of the blank by the demolding support plate 6544, effectively improves stamping quality and overcomes the shortcomings of low stamping quality in existing technologies. The hydraulic cylinder 64 provides power for both stamping and demolding, working in conjunction with the drive device 523 to drive multiple demolding push plates 525 to operate synchronously, achieving linkage between stamping and demolding and multi-station synchronous processing, significantly improving extraction efficiency and solving the problem of lacking rapid automated demolding. The soft material of the flexible conveyor belt prevents breakage when products fall, improving product qualification rate. Protective structures such as the casing extend the service life of components and ensure operational safety. The coordinated operation of all structures enables fully automated continuous operation, further improving overall production efficiency.

[0022] During the application of this device, the various structures can be fixedly installed using bolts, welding, screws, or some flexible snap-fit ​​installations. If a detachable design is required, bolt or screw installation can be selected. If a stable installation is required, welding installation can be selected. The specific requirements can be flexibly selected according to the application requirements.

[0023] In this technical solution, the controller is a Siemens S7-200 SMART series PLC (model CPU SR40), installed inside the control frame 66. The controller surface is equipped with a 7-inch Weintek TK6071IP touchscreen display for parameter setting and operating status display. The drive motor 5233 is a Panasonic MSMD042G1U servo motor (400W power, rated speed 3000rpm), with a 17-bit absolute encoder (Panasonic A6 series matching encoder) installed on the motor shaft end, enabling stepless speed regulation and precise adjustment of rotation angle. The motor output is connected to a Newcatel PLF60 planetary gearbox 5234 reducer (reduction ratio 5:1-100:1, selected according to requirements) to improve torque and control speed. The pressure sensor is an Omron E8F2 series (range 0-5MPa, output signal 4-20mA), installed at the bottom output end of the hydraulic cylinder 64. The displacement sensor is a Keyence IL-1000. A laser displacement sensor (measuring range 0-300mm, accuracy ±0.01mm) is mounted on the outside of the ring-shaped base 51. The circuit system is powered by AC 220V mains power converted to DC 24V via a Mean Well MW-100-24 switching power supply to power the PLC, sensor, and servo driver. The servo driver (model Panasonic MADHT1507) receives pulse signals from the PLC to control the operation of the drive motor 5233. Specifically, the PLC's digital output terminals are connected to the coil of the hydraulic cylinder 64 electromagnetic directional valve (model 4V210-08) and the servo driver's enable terminal, respectively. The analog output terminals are connected to the servo driver's speed control terminal. The signal output terminals of the pressure sensor and displacement sensor are connected to the PLC's analog input terminals, respectively. The encoder signal terminal is connected to the servo driver's feedback terminal. The display screen communicates with the PLC via an RS485 communication interface. Connections: During use, depending on specific application requirements, a slotted photoelectric sensor (model Omron E3Z-G61) can be installed on the outside of the slip ring 524 to detect the reset position of the slip ring 524. A diffuse reflection photoelectric sensor (model Banner QS18VN6LD) can be installed at the outlet of the discharge chute 522 to detect the product discharge status. Infrared through-beam sensors (model Autonics BEN3M-MFR) can be installed on both sides of the flexible conveyor belt to detect whether the product conveying is off-center. The signals of the above sensors are all connected to the PLC input terminal to realize automatic monitoring of the equipment's operating status and abnormal alarms. All electronic components are connected to the main circuit through waterproof aviation plugs to ensure stable and reliable circuit connections.
