[0002] The static press is an indispensable piece of equipment in the compression process of electrical materials. During use, the electrical materials to be compressed are added into the processing chamber. Then, the hydraulic station is operated to make the hydraulic cylinder move the plug equipped with a wireless temperature sensor to seal the top of the processing chamber. Then, oil is injected for compression. The wireless temperature sensor transmits the temperature changes of the inner processing chamber to the temperature receiver for observation.

[0003] The existing plug and hydraulic cylinder output end are fixed with multiple bolts. The wireless temperature sensor is placed between the plug and the hydraulic cylinder. When the wireless temperature sensor is damaged after long-term use, it needs to be replaced with a new one. When replacing it, the bolts fixing the plug and the hydraulic cylinder need to be removed, and then the wireless temperature sensor needs to be taken out for replacement. The plug is relatively heavy and needs to be supported and moved by hand, which makes the disassembly and assembly process time-consuming and laborious, and replacing the wireless temperature sensor is inconvenient. Utility model content:

[0004] Therefore, the purpose of this utility model is to provide a static pressure sealing mechanism to overcome the problems of existing technology where the existing plug and hydraulic cylinder output end are fixed with multiple bolts, the wireless temperature sensor is placed between the plug and the hydraulic cylinder, and when the wireless temperature sensor is damaged after long-term use, it needs to be replaced with a new wireless temperature sensor. When replacing it, the bolts fixing the plug and the hydraulic cylinder need to be removed, and then the wireless temperature sensor needs to be taken out for replacement. The plug is relatively heavy and needs to be supported and moved by hand, which makes the disassembly and assembly process time-consuming and laborious, and the replacement of the wireless temperature sensor inconvenient.

[0005] This utility model is implemented by the following technical solution:

[0006] A hydrostatic press plugging mechanism includes a hydraulic cylinder and a plug. The output end of the hydraulic cylinder has an oblique hole. The hydraulic cylinder and the plug are slidably connected by a connecting assembly. The side end of the plug has a placement hole with the same diameter as the oblique hole. A positioning assembly is slidably fitted inside the placement hole. A slider is fixedly connected to the bottom surface of the positioning assembly. The slider is slidably disposed in a groove. The groove is located on the surface of the plug and communicates with the placement hole. A compression spring is fixedly connected between the plug and the slider and disposed in the groove. A wireless temperature sensor is slidably disposed inside the positioning assembly. The sensing end of the wireless temperature sensor protrudes from the plug and is slidably connected to it. A sealing ring is slidably fitted onto the sensing end of the wireless temperature sensor. The sealing ring is embedded in the placement hole and fixedly connected to the plug. The compression spring can push the positioning assembly into the oblique hole through the slider to limit the position of the plug.

[0007] Preferably, the placement hole is inclined and the vertical plane containing the straight line connecting the centers of the placement holes is the same as the vertical plane containing the straight line connecting the centers of the inclined holes.

[0008] Preferably, the connecting assembly includes two vertically arranged dovetail grooves, the dovetail grooves are formed on the side wall of the plug, the placement hole is disposed between the two dovetail grooves, and a dovetail block is slidably fitted inside the dovetail groove, the side wall of the dovetail block is fixedly connected to the output end of the hydraulic cylinder.

[0009] Preferably, the positioning component includes a fixed frame that is slidably disposed within the placement hole, the wireless temperature sensor being slidably disposed within the fixed frame, a baffle being hinged to one end of the fixed frame via a pin, one side wall of the baffle being in contact with the side wall of the wireless temperature sensor, the other side wall of the baffle being in contact with the side wall of the hydraulic cylinder, and the sensing end of the wireless temperature sensor extending out of the fixed frame and through the plug.

[0010] Preferably, the center of gravity of the baffle is located directly below the line containing the center of the placement hole.

The pulley is rolled in a groove, which is formed on the surface of the fixed frame.

[0012] The advantages of this invention are: the hydraulic cylinder and the plug are slidably connected by a connecting component. When the wireless temperature sensor needs to be replaced, the plug only needs to be slid to move a distance so that the placement hole coincides with the inclined hole. At this time, the compression spring pushes the positioning component with the wireless temperature sensor through the slider to move and slide from the placement hole to limit the plug. This facilitates the replacement of the wireless temperature sensor while supporting the plug. There is no need to repeatedly move the plug.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1-5 As shown, this utility model provides the following technical solution: a static pressure machine sealing mechanism, including a hydraulic cylinder 1 and a plug 3. The output end of the hydraulic cylinder 1 has an oblique hole 2. The hydraulic cylinder 1 and the plug 3 are slidably connected by a connecting component. The side end of the plug 3 has a placement hole 6. The placement hole 6 has the same diameter as the oblique hole 2. A positioning component is slidably disposed in the placement hole 6. A slider 10 is fixedly connected to the bottom surface of the positioning component. The slider 10 is slidably disposed in a slide groove 9. The slide groove 9 is opened on the surface of the plug 3 and communicates with the placement hole 6. A compression spring 11 is fixedly connected between the plug 3 and the slider 10 and disposed in the slide groove 9. A wireless temperature sensor 12 is slidably disposed in the positioning component. The sensing end of the wireless temperature sensor 12 passes through the plug 3 and is slidably connected to it. A sealing ring 13 is slidably sleeved on the sensing end of the wireless temperature sensor 12. The sealing ring 13 is embedded in the placement hole 6 and fixedly connected to the plug 3. The compression spring 11 can push the positioning component into the oblique hole 2 through the slider 10 to limit the plug 3.

[0025] Please combine Figure 1As shown, during use, the electrical material to be compressed is added to the processing chamber. Then, the hydraulic station is operated to move the hydraulic cylinder 1, which moves the plug 3 fitted with the wireless temperature sensor 12, to seal the top of the processing chamber. Oil is then injected for compression. The wireless temperature sensor 12 transmits the constant temperature changes inside the processing chamber to the temperature receiver for observation. When the wireless temperature sensor 12 is damaged after long-term use and needs replacement, the operator pushes the plug 3 upwards. The plug 3 moves the connecting component, which in turn moves the positioning component in the placement hole 6. When the placement hole 6 gradually moves and aligns with the inclined hole 2, the compression spring 11 pushes the slider 10 to slide in the groove 9. The slider 10 moves the positioning component, which gradually slides into the inclined hole 2. The positioning component causes the wireless temperature sensor 12 to gradually slide out of the inclined hole 2. At this point, the positioning component does not completely slide out of the placement hole 6, providing support and limiting for the plug 3. Figure 5 As shown, open the positioning component, remove the wireless temperature sensor 12 that needs to be replaced, insert the new wireless temperature sensor 12, and then close the positioning component. Then, use a screwdriver to push the positioning component to move. When the positioning component slides out of the inclined hole 2, the positioning component with the wireless temperature sensor 12 has slid into the placement hole 6. The plug 3 moves downward to reset due to its own gravity. The plug 3 drives the positioning component to move and reset, and the positioning component drives the wireless temperature sensor 12 to move and reset. This makes it easy to replace the wireless temperature sensor 12 while supporting the plug 3. There is no need to repeatedly move the plug 3. The disassembly and assembly process is time-saving and labor-saving, and it is convenient to replace the wireless temperature sensor 12.

[0026] The placement hole 6 is set at an angle, and the vertical plane containing the straight line connecting the centers of the placement hole 6 and the vertical plane containing the straight line connecting the centers of the inclined hole 2 are the same plane. This makes it easy for the positioning component in the placement hole 6 to slide into the inclined hole 2 to limit the stopper 3 when the placement hole 6 moves to coincide with the inclined hole 2.

[0027] Please combine Figure 2 As shown in the embodiment of the connecting component, the connecting component includes two vertically arranged dovetail grooves 4, the dovetail grooves 4 are opened on the side wall of the plug 3, the placement hole 6 is arranged between the two dovetail grooves 4, and the dovetail block 5 is slidably attached to the dovetail groove 4. The side wall of the dovetail block 5 is fixedly connected to the output end of the hydraulic cylinder 1.

[0028] Please combine Figure 2 As shown, during use, when the worker pushes the plug 3 upward, the plug 3 causes the dovetail groove 4 to slide on the dovetail block 5. When the positioning component is inserted into the inclined hole 2, the plug 3 stops moving.

[0029] When the positioning component is pushed to slide completely into the placement hole 6, the plug 3 descends due to its own gravity. The plug 3 drives the dovetail groove 4 to slide on the dovetail block 5. When the top surface of the dovetail groove 4 is in contact with the top surface of the dovetail block 5, it stops moving. At this time, the plug 3 also moves to its original position.

[0030] Please combine Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown in the embodiment of the positioning component, the positioning component includes a fixed frame 7 that is slidably disposed within the placement hole 6, and a wireless temperature sensor 12 that is slidably disposed within the fixed frame 7. One end of the fixed frame 7 is hinged to a baffle 8 via a pin. One side wall of the baffle 8 is in contact with the side wall of the wireless temperature sensor 12, and the other side wall of the baffle 8 is in contact with the side wall of the hydraulic cylinder 1. The sensing end of the wireless temperature sensor 12 extends out of the fixed frame 7 and out of the plug 3.

[0031] Please combine Figure 1 As shown, during use, when the plug 3 moves upward, the plug 3 drives the fixing frame 7 to move, the fixing frame 7 drives the baffle 8 to move, and the fixing frame 7 drives the internal wireless temperature sensor 12 to move. When the placement hole 6 corresponds to the inclined hole 2, the compression spring 11 pushes the slider 10 to move, the slider 10 drives the fixing frame 7 to move, and the fixing frame 7 drives the baffle 8 to move and gradually pass through the inclined hole 2. The fixing frame 7 also gradually passes through the inclined hole 2. Figure 5 As shown, the baffle 8 is then rotated to separate from the wireless temperature sensor 12 in the mounting bracket 7. After replacing the wireless temperature sensor 12, the baffle 8 is rotated to block the wireless temperature sensor 12. Then, the operator pushes the baffle 8 with a screwdriver to move it. The baffle 8 drives the mounting bracket 7 to move and gradually slide out of the inclined hole 2. The mounting bracket 7 drives the replaced wireless temperature sensor 12 inside to gradually insert into the placement hole 6. When the baffle 8 is fully inserted into the placement hole 6, the plug 3 moves downward due to gravity. The plug 3 drives the mounting bracket 7 to move and reset. The mounting bracket 7 drives the wireless temperature sensor 12 to move and reset.

[0032] The center of gravity of the baffle 8 is directly below the line containing the center of the placement hole 6, keeping the baffle 8 in a vertical position so that it can limit the wireless temperature sensor 12.

[0033] A counterweight ring 14 is slidably sleeved on the sensing end of the wireless temperature sensor 12. The counterweight ring 14 is set on the fixed frame 7. A connecting rod 15 is fixedly connected to the bottom and top surfaces of the counterweight ring 14. A pulley 16 is rotatably connected to the other end of the connecting rod 15. The pulley 16 is rolled in the groove 17, which is formed on the surface of the fixed frame 7.

[0034] Please combine Figure 1 , Figure 4 , Figure 5 As shown, during use, when the baffle 8 slides through the inclined hole 2, the rotating baffle 8 separates from the wireless temperature sensor 12. Due to gravity, the counterweight ring 14 slides tilted in the placement hole 6. The placement hole 6 drives the connecting rod 15 to slide, and the connecting rod 15 drives the pulley 16 to roll in the groove 17. The counterweight ring 14 causes the wireless temperature sensor 12 to slide partially out of the fixing bracket 7, facilitating the removal of the wireless temperature sensor 12. Then, the wireless temperature sensor 12 is manually pulled out for replacement with a new wireless temperature sensor 12. Sensor 12 is inserted into the mounting bracket 7. The output end of the wireless temperature sensor 12 passes through the counterweight ring 14 and pushes the counterweight ring 14 to move. The counterweight ring 14 drives the connecting rod 15 to move. The connecting rod 15 drives the pulley 16 to roll in the groove 17, reducing the friction between the pulley 16 and the mounting bracket 7, which facilitates the sliding of the counterweight ring 14. When the baffle 8 is completely slid into the placement hole 6, the plug 3 moves downward due to gravity. When the top surface of the dovetail groove 4 is in contact with the top surface of the dovetail block 5, it stops moving. At this time, the plug 3 also moves to its original position.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
