Through the cooperation of the cylinder, the inclined block plate, the first square inclined groove and the first spring, the composite movement of the movable seat moving back horizontally and lifting vertically is realized. Only a single cylinder is required to drive it, which simplifies the structure while ensuring the positioning accuracy error of the movable seat. The circular mold can be clamped in the center by the clamping mechanism, which utilizes the linkage of the second tension spring, the drive plate, the L-shaped movable plate and the second inclined slot. This not only firmly clamps the mold but also prevents damage to the mold surface due to excessive pressure. The mechanism is linked to the movement of the movable seat. When the movable seat is lifted upward, the drive plate is limited and stationary, automatically triggering the clamping mechanism to clamp the mold. No additional power source or control program is required, reducing failure points. The mold loading and unloading process is simple and fast. After placing the mold, the cylinder is activated to complete the clamping. After the grinding is completed, the cylinder retracts and automatically releases, greatly shortening the loading and unloading time and the single-cycle clamping time. By setting up the matching mechanism and the grinding mechanism, and through the mechanical structure of the linkage rod, the polished rod, the L-shaped path groove and the guide column, the linkage between the moving mechanism and the grinding mechanism is realized. When the moving seat is lifted, the grinding mechanism will move downward under the action of the matching mechanism. The two-way movement can significantly improve production efficiency. The stepper motor drives the rotating bar to drive the grinding disc to rotate, which can accurately control the grinding force and fineness according to different grinding requirements. At the same time, the grinding disc is connected to the positioning bar by bolts, which is convenient for quick replacement of grinding discs of different materials and particle sizes to meet various processing technologies such as coarse grinding, fine grinding, and polishing. The moving mechanism, clamping mechanism, grinding mechanism and matching mechanism work closely together to realize the automation of the entire process from mold clamping, positioning, grinding to loosening and unloading, reducing manual intervention and improving production efficiency. The various mechanisms work together, the moving mechanism accurately positions, the clamping mechanism stably clamps, the grinding mechanism accurately grinds, and the matching mechanism ensures synchronous movements to ensure the mold grinding accuracy.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

A circular mold is placed inside the discharge trough 12, and a clamping mechanism is provided inside the movable seat 8. The clamping mechanism is used to position the circular mold. A grinding mechanism 25 is provided above the fixed frame 5, and a matching mechanism is provided on the side of the fixed frame 5. The movable mechanism 7 is linked with the grinding mechanism 25 through the matching mechanism. The movable mechanism 7, the clamping mechanism, the grinding mechanism 25 and the matching mechanism cooperate closely to realize the automation of the entire process from mold clamping, positioning, grinding to loosening and unloading, reduce manual intervention, and improve production efficiency. The various mechanisms work together, the movable mechanism 7 accurately positions, the clamping mechanism stably clamps, the grinding mechanism 25 accurately grinds, and the matching mechanism ensures synchronous action to ensure the grinding accuracy of the mold.

[0019] The front end of the fixed frame 5 is provided with a connecting plate, and the surface of the connecting plate is provided with a cylinder 15. A rectangular groove is provided under the movable seat 8, and a first square oblique groove 9 is provided on both sides of the rectangular groove. An inclined block plate 13 is provided inside the rectangular groove, and the end of the inclined block plate 13 is movably engaged in the first square oblique groove 9. A first spring 10 is installed inside the first square oblique groove 9. The top of the first spring 10 is connected to the inclined block plate 13, and the output end of the cylinder 15 is connected to the center of the inclined block plate 13. A straight groove 16 is provided on the surface of the auxiliary plate 6, and a first boss 14 is installed at the end of the inclined block plate 13. The surface of the first boss 14 is slidably arranged in the straight groove 16. When the cylinder 15 is not started, the first spring 10 is in a naturally extended state, pushing the inclined block plate 13 upward so that its end is engaged with the top of the first square oblique groove 9. At this time, the inclined block plate 13 is fitted with the inclined surface of the first square oblique groove 9 through the top inclined surface to form a self-locking structure. When the outgoing end extends out, it will push the center of the inclined block plate 13. At this time, the inclined block plate 13 will push the moving seat 8 to move under the elastic force of the first spring 10 and its inclined surface, and the moving seat 8 will move toward the rear of the fixed frame 5. When the moving seat 8 moves to the extreme rearward movement position inside the fixed frame 5, the cylinder 15 continues to apply thrust. At this time, the inclined block plate 13 can no longer push the moving seat 8 to move horizontally, and its inclined surface and the inclined surface of the first square inclined groove 9 will slide relative to each other, forcing the inclined block plate 13 to compress the first spring 10, and the inclined block plate 13 has an extrusion force on the first square inclined groove 9, so that the moving seat 8 is lifted upward as a whole, so that the circular mold placed in the discharge trough 12 is tightly fitted with the grinding mechanism 25 above, entering the precise grinding state, and the first protrusion 14 at the end of the inclined block plate 13 slides in the linear groove 16 of the auxiliary plate 6, ensuring that the inclined block plate 13 only moves back and forth along a straight line, and at the same time provides a horizontal guide for the moving seat 8 to ensure movement accuracy.

[0020] The clamping mechanism includes a driving plate 18, a central groove 17 is provided inside the movable seat 8, the driving plate 18 is movably installed in the central groove 17, the driving plate 18 is movably installed in the central groove 17, a second tension spring 24 is provided inside the central groove 17, the second tension spring 24 is above the driving plate 18, the bottom end of the second tension spring 24 is connected to the driving plate 18, and connecting strips 19 are provided at both ends of the top of the driving plate 18. L-shaped movable plates 20 are movably provided at both ends of the top of the central groove 17, the top of the L-shaped movable plate 20 movably passes through the discharge trough 12, and a clamping surface 23 is installed on the top of the L-shaped movable plate 20, and the clamping surface 23 is movably located in the discharge trough 12. The bottom of the L-shaped movable plate 20 A second inclined groove 21 is provided, and a second boss 22 is provided on the top of the connecting bar 19. The surface of the second boss 22 is movably engaged with the surface of the second inclined groove 21. The second tension spring 24 is in a natural pulling state, and the driving plate 18 is fixed downward on the top of the center groove 17 by tension. The driving plate 18 pushes the L-shaped movable plate 20 outward through the connecting bars 19 and the second boss 22 at both ends. At this time, the clamping surface 23 is away from the center of the discharge trough 12, which is convenient for placing the circular mold. When the driving plate 18 moves downward, the second boss 22 slides downward along the inclined surface of the second inclined groove 21. Due to the inclination of the inclined groove, the L-shaped movable plate 20 is forced to move inward, driving the clamping surface 23 to clamp the outer periphery of the mold.

[0021] A protrusion 39 is provided on the middle end surface of the driving plate 18, and the protrusion 39 is movable through the movable seat 8. A groove 40 is provided at the rear end inside the fixed frame 5, and the groove 40 corresponds to the protrusion 39. When the movable seat 8 reaches the extreme rearward position inside the fixed frame 5, the protrusion 39 is aligned with the groove 40 at the rear end of the fixed frame 5 and inserted therein, forming a mechanical limit. Then, when the movable seat 8 is lifted upward, the position of the protrusion 39 is limited due to the obstruction of the groove 40. Therefore, when the movable seat 8 is lifted upward, the driving plate 18 remains stationary, so that the second boss 22 slides downward along the inclined surface of the second inclined groove 21, and the L-shaped movable plate 20 is forced to move inward, driving the clamping surface 23 to clamp the outer periphery of the mold.

[0022] The bottom end of the L-shaped main frame 26 is provided with a recycling frame 27 at the rear of the fixed frame 5. The grinding mechanism 25 includes an L-shaped main frame 26. The bottom end of the L-shaped main frame 26 is movably mounted inside the recycling frame 27. A third spring 28 is provided inside the recycling frame 27. The top end of the third spring 28 is connected to the bottom surface of the L-shaped main frame 26. A circular matching groove 29 is provided on the top of the L-shaped main frame 26. A grinding component is provided inside the circular matching groove 29. A slider is provided at the bottom end of the L-shaped main frame 26, which cooperates with the inner wall of the recycling frame 27. The L-shaped main frame 26 is at the top end in the recycling frame 27 under the elastic force of the third spring 28. The grinding component in the circular matching groove 29 keeps a certain distance from the mold to be processed and does not contact. When the movable seat 8 drives the clamping mechanism and the mold to move backward to the limit position inside the fixed frame 5, the movable seat 8 is lifted upward, and the L-shaped main frame 26 overcomes the elastic force of the third spring 28 and moves downward, so that the grinding component in the circular matching groove 29 contacts the mold surface and starts the grinding operation.

[0023] The grinding assembly includes a rotating bar 31, which is rotatably installed in the circular matching groove 29. A positioning bar 32 is provided at the end of the rotating bar 31, and a grinding disc 33 is installed at the bottom end of the positioning bar 32 through bolts. A stepping motor 30 is provided at the top of the L-shaped main frame 26, and the output end of the stepping motor 30 is connected to the middle part of the rotating bar 31. After the stepping motor 30 is started, the output shaft drives the rotating bar 31 to rotate around the central axis in the circular matching groove 29. The rotating bar 31 drives the grinding disc 33 to rotate synchronously through the positioning bar 32 at the end to form the circular motion required for grinding. The positioning bar 32 fixes the grinding disc 33 through bolts to ensure that the grinding disc remains stable during rotation to avoid falling off due to centrifugal force. The bolt connection method facilitates the rapid replacement of different types of grinding discs to meet different grinding needs.

[0024] The cooperating mechanism includes a linkage rod 37, the middle end of the linkage rod 37 is connected to the fixed frame 5 through a rotating shaft, and the rear ends of the two linkage rods 37 are connected to a polished rod 38. A connecting groove 34 is provided on the surface of the L-shaped main frame 26, and the surface of the polished rod 38 is movably installed in the connecting groove 34. The linkage rod 37 uses the rotating shaft on the side of the fixed frame 5 as a fulcrum to form a lever structure. If the front end moves upward and the rear end swings downward, the polished rod 38 slides along the connecting groove 34 of the L-shaped main frame 26, pushing the L-shaped main frame 26 to move downward, so that the grinding assembly approaches the mold surface and triggers the grinding action. If the front end moves downward and the rear end swings upward, the polished rod 38 drives the L-shaped main frame 26 to reset upward under the elastic force of the third spring 28, so that the grinding assembly moves away from the mold and stops grinding.

[0025] An L-shaped path groove 35 is provided on the surface of the fixed frame 5, and a guide column 36 is fixedly installed on the side of the movable seat 8. The surface of the guide column 36 is movably engaged in the L-shaped path groove 35, and the end of the guide column 36 protrudes from the L-shaped path groove 35. The front end of the linkage rod 37 cooperates with the guide column 36. When the movable seat 8 moves horizontally, the guide column 36 will simultaneously move along the horizontal section of the L-shaped path groove 35. When the movable seat 8 reaches the extreme rearward position inside the fixed frame 5 and is lifted upward, the guide column 36 will simultaneously move upward along the tail end of the L-shaped path groove 35. At this time, the guide column 36 has an upward squeezing effect on the front end of the linkage rod 37, so that the front end of the linkage rod 37 will move upward.

[0026] Working principle: First, in the initial state, the cylinder 15 is not started, the first spring 10 pushes the inclined plate 13 upward, and its end is clamped on the top of the first square inclined groove 9, and the movable seat 8 is fixed to the front end of the fixed frame 5 by the inclined self-locking. The second tension spring 24 is in a natural pulling state, and the driving plate 18 is fixed downward on the top of the center groove 17 by tension. The driving plate 18 pushes the L-shaped movable plate 20 outward through the connecting strips 19 and the second protrusion 22 at both ends. At this time, the clamping surface 23 is away from the center of the discharge groove 12. Then, the circular mold is placed in the discharge groove 12. Then, the output end of the cylinder 15 extends to push the center of the inclined plate 13 backward. Since the inclined surface at the end of the inclined plate 13 is matched with the first square inclined groove 9, the inclined surface of the first square inclined groove 9 is fixed to the front end of the fixed frame 5. When the movable seat 8 is closed, it pushes the movable seat 8 to move horizontally toward the rear of the fixed frame 5 through the inclined surface when it moves backward. The guide column 36 slides along the horizontal section of the L-shaped path groove 35 to ensure the linear movement of the movable seat 8. The first boss 14 is guided in the linear groove 16 of the auxiliary plate 6 to prevent the inclined block plate 13 from deflecting. When the movable seat 8 reaches the rear end limit position of the fixed frame 5, the protrusion 39 is inserted into the groove 40 to form a mechanical limit to ensure positioning accuracy. The cylinder 15 continues to apply thrust, and the inclined block plate 13 can no longer push the movable seat 8 to move horizontally. Its inclined surface slides relative to the first square inclined groove 9, compressing the first spring 10 and moving downward, and lifting the movable seat 8 upward by the reaction force. When the movable seat 8 is lifted, the protrusion 39 is limited by the groove 40 , the driving plate 18 remains stationary, the second protrusion 22 slides downward along the second inclined groove 21, forcing the L-shaped movable plate 20 to move inward, and the clamping surface 23 hugs the outer periphery of the mold to complete the centering positioning and clamping. During the lifting process of the movable seat 8, the guide column 36 enters the vertical section along the L-shaped path groove 35, and its protruding end presses the front end of the linkage rod 37 upward. The linkage rod 37 swings with the rotating shaft as the fulcrum, and the rear end pushes the L-shaped main frame 26 downward through the light rod 38, compressing the third spring 28 to make the grinding sheet 33 contact the mold surface. Finally, the stepping motor 30 starts, driving the rotating bar 31 to drive the grinding sheet 33 to rotate at high speed. The lifting height of the movable seat 8 matches the swing amplitude of the linkage rod 37 to ensure that the grinding sheet 33 The mold is fitted with the set pressure. After the grinding is completed, the cylinder 15 retracts, the first spring 10 pushes the inclined block plate 13 to reset, the movable seat 8 drops and moves forward with the cylinder pull, the guide column 36 returns to the horizontal section along the L-shaped path groove 35, the front end of the linkage rod 37 loses extrusion, and the L-shaped main frame 26 resets upward under the action of the third spring 28. The grinding sheet 33 is separated from the mold. When the movable seat 8 moves forward, the protrusion 39 is separated from the groove 40, the driving plate 18 moves with the movable seat 8, the second tension spring 24 pulls the driving plate 18 upward, the second protrusion 22 is reset along the second inclined groove 21, the L-shaped movable plate 20 is stretched outward, the clamping surface 23 releases the mold, the polished mold is taken out manually or mechanically, and enters the next processing cycle.
