DETAILED DESCRIPTION

[0022] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be further described below with reference to the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0024] Embodiment one: as shown in Figure 1 , Figure 3 and Figure 4 , the present application provides a sealing ring processing press, including support 1, support 1 top is equipped with hydraulic cylinder 3, and support 1 middle part is fixedly connected with mounting frame 4, mounting frame 4 top is equipped with mold 6, mounting frame 4 bottom is equipped with movable mechanism 5, movable mechanism 5 top is equipped with discharging mechanism 7;

[0025] Discharging mechanism 7 includes top plate 71, the bottom center of top plate 71 is fixedly connected with support rod 711, the outer surface of support rod 711 is rotatably connected with rotating sleeve 73, the outer surface of rotating sleeve 73 top end is fixedly connected with rotating frame 74, rotating frame 74 bottom is rotatably connected with four linkage rods 77, the surface of top plate 71 is provided with limit hole 72, the inside of limit hole 72 is slidably connected with moving block 76, the bottom of moving block 76 is rotatably connected with one end of linkage rod 77.

[0026] Movable mechanism 5 includes lifting plate 51, lifting plate 51 top center is fixedly connected with support rod 711, both ends of support rod 711 are fixedly connected with movable rod 53, the outer surface of movable rod 53 bottom end is slidably connected with fixed plate 52.

[0027] The specific settings and effects of the embodiment will be described below. During the processing of the sealing ring, the raw material is first poured into the mold 6, and the raw material is formed in the mold 6 through the extrusion of the upper mold base 2. When the molding is completed, the spring 55 can be used to push the lifting plate 51 upward. With the lifting of the lifting plate 51, the top plate 71 and the support rod 711 will also rise, and in the process, the processed sealing ring is pushed out of the mold 6 through the discharge rod 78. This process not only improves the production efficiency, but also facilitates the operator to quickly take out the molded sealing ring, which provides convenience for the next round of processing.

[0028] When different molds 6 are replaced for processing sealing rings, the rotating sleeve 73 can be adjusted to drive the rotating frame 74 to rotate. During the rotation of the rotating frame 74, the four linkage rods 77 move synchronously, thereby affecting the four moving blocks 76 connected thereto. In this process, the linkage rod 77 will apply a torque to cause the moving block 76 to start moving, and the moving process is controlled by the limiting hole 72. The limiting hole 72 can effectively ensure the accurate movement of the moving block 76 along the straight trajectory, avoiding deviation or misplacement.

[0029] When the rotating frame 74 rotates, the four linkage rods 77 precisely cooperate to make the four moving blocks 76 move synchronously, and gather or disperse as needed. This synchronous movement mechanism can adjust the positions of the four discharge rods 78 according to the size of the mold 6. By adjusting the rotation angle of the rotating frame 74, the positions of the four moving blocks 76 can be quickly adjusted,

[0030] In addition, through the precise control of the linkage rod 77 and the moving block 76, the adjustment process of the mold 6 during the processing of sealing rings of different batches and different specifications can be more accurate, avoiding production problems caused by size mismatch.

[0031] Embodiment two: as shown in Figure 2 and Figure 4 , wherein the bottom of each of the two moving blocks 76 is fixedly connected with a fixed frame 79, and the bottom plate 71 is provided with two telescopic rods 75. The two ends of the telescopic rod 75 are fixedly connected with the fixed frame 79, and the top of the moving block 76 is fixedly connected with the discharge rod 78. The side wall of the fixed plate 52 is fixedly connected with the mounting frame 4, and the spring 55 is arranged between the lifting plate 51 and the fixed plate 52. The spring 55 is sleeved on the outer surface of the movable rod 53, and the bottom end of the movable rod 53 is fixedly connected with the limiting block 56. The inner cavity of the bracket 1 is provided with the upper mold base 2 at the top end, and the upper mold base 2 is fixedly connected with the output end of the hydraulic cylinder 3. The top end of the movable rod 53 is fixedly connected with the pressure plate 54.

[0032] The effect achieved by the whole embodiment is that during the process of the hydraulic cylinder 3 controlling the downward movement of the upper die holder 2, in addition to realizing the extrusion molding of the sealing ring, the downward movement of the hydraulic cylinder 3 will also push the pressure plate 54 to move downward. The downward movement of the pressure plate 54 drives the lifting plate 51 and the movable rod 53 to move downward synchronously, which changes the position of the ejection mechanism 7 and prepares for the rapid removal of the sealing ring.

[0033] During this process, the lifting plate 51 will extrude the spring 55 on the outer surface of the movable rod 53, causing the compression of the spring 55. The spring 55 during compression plays a role of buffering and control, ensuring that the sealing ring will not be subjected to excessive pressure during extrusion, thereby avoiding damage during molding. When the molding of the sealing ring is completed, the hydraulic cylinder 3 will make the upper die holder 2 reset upward, at which time the spring 55 begins to restore its original shape, generating a reverse force to push the lifting plate 51 to move upward.

[0034] With the upward movement of the lifting plate 51, the ejection mechanism 7 rises, pushing the molded sealing ring out of the mold 6. During this process, the springback force of the spring 55 plays a key role in ensuring that the lifting plate 51 can smoothly return to its original position and push the ejection mechanism 7 to smoothly push out the sealing ring, completing the entire processing flow.

[0035] When the rotating frame 74 drives the synchronous movement of the moving block 76 through the linkage rod 77, the two telescopic rods 75 will also extend and retract with the rotation of the rotating frame 74. This design ensures the synchronous movement of the lifting plate 51 and the movable rod 53, while enhancing the stability of the system. When the telescopic rods 75 are extended, they cooperate with the fixed frame 79 to provide additional support and stability, preventing deviation or imbalance during operation.

[0036] The method of using the device and the working principle are as follows: during the process of the hydraulic cylinder 3 controlling the downward movement of the upper die, not only will the material be extruded to form a sealing ring, but also the pressure plate 54 will be pushed. After the pressure plate 54 is stressed, it drives the lifting plate 51 and the movable rod 53 to move downward together, thereby changing the position of the ejection mechanism 7. During this period, the lifting plate 51 will extrude the spring 55 on the outer surface of the movable rod 53, causing the compression of the spring 55. After the molding process is completed, the upper die holder 2 resets upward, at which time the spring 55 loses external pressure and begins to rebound, pushing the lifting plate 51 to move upward in the opposite direction. With the upward movement of the lifting plate 51, the ejection mechanism 7 is driven to move upward synchronously, thereby ejecting the formed sealing ring.

[0037] When the sealing ring of corresponding size is processed according to the mold 6 of different size, the rotation of the rotating sleeve 73 can drive the rotating frame 74 to move. In this process, the rotating frame 74 will synchronously drive the four linkage rods 77, and the linkage rods 77 will in turn exert force on the moving block 76 to make the moving block 76 start to move. During the movement, the moving block 76 is limited by the limiting hole 72 and can only move in a straight line direction, so as to ensure that when the rotating frame 74 rotates, the four linkage rods 77 can accurately control the synchronous movement of the four moving blocks 76, and the four discharge rods 78 realize the gathering or dispersing action, so as to adapt to different types of molds 6.

[0038] During the movement of the rotating frame 74 driven by the linkage rod 77 to move the moving block 76, the two telescopic rods 75 will be correspondingly telescopic. At the same time, the fixed frame 79 can play the effect of stable reinforcement, so as to ensure that the four moving blocks 76 always move synchronously and coordinately, and maintain the stability and accuracy of the operation of the overall structure.

[0039] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments shall still fall within the protection scope of the present application.
