Description

Technical Field

[0001] This invention relates to the field of hot pressing molding technology, specifically to a hot pressing molding equipment for silicone rubber gaskets. Background Technology

[0002] Hot pressing is a simple and common processing method in the plastics industry. It involves heating a mold, injecting a sample, and using pressure to fix the mold to a heating plate. The melting temperature and time of the sample are controlled to allow it to melt, harden, cool, and then the mold is removed to produce the finished product. Compared to other processing methods, hot pressing has advantages such as inexpensive molds and uniform product thickness. Its applications have expanded from early military map models and aircraft hoods to include refrigerator door liners, car mudguards, and other products with uniform thickness.

[0003] Existing silicone rubber gasket thermoforming equipment requires steps such as material injection, pressurization, heating, cooling, and demolding. However, heating consumes significant energy and time to fully melt the raw material, and cooling takes time to form the gasket. During this process, the thermoforming equipment cannot proceed to the next batch of gaskets. This results in substantial time and energy consumption for each product, significantly reducing the overall production efficiency of silicone rubber gaskets. Therefore, we propose a silicone rubber gasket thermoforming equipment. Summary of the Invention

The inner wall of the drive ring is rotatably connected to the outer wall of the bottom end of the hydraulic telescopic rod. The rotation mechanism is used to drive the drive ring to rotate and store force each time the hydraulic telescopic rod extends or retracts. After hot pressing is completed, it drives the rotating ring and the rotating disk to rotate at a set angle, so that the next set of device boxes containing raw materials to be hot pressed rotates to the hot pressing area for hot pressing.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention provides a silicone rubber gasket hot pressing molding device. When the hydraulic telescopic rod moves downward, it drives the connecting rod downward, causing the lower pressure rod to move downward and insert into the mounting frame, pushing the upper module downward. During the downward movement of the upper module, the lifting block slides down within the lifting groove, compressing the first spring. Simultaneously, the pushing rod moves downward, pushing the gas in the sleeve downward to the bottom of the annular groove, thereby pushing the annular baffle upward within the annular groove, blocking the side of the lower module, thus surrounding the raw material. As the upper module moves downward, it compresses the raw material heated by the addition plate, hot pressing the silicone rubber raw material into the specified shape. Simultaneously, when the lower module moves to its lowest point, the high temperature of the device box causes the liquid temperature below the lifting plate to rise and expand, pushing the lifting plate upward, displacing the gas or... The liquid is pushed into the sliding groove, causing the snap-fit ​​block to push the lower module to one side. At this time, due to the upward movement of the annular baffle and the downward movement of the upper module, one end of the snap-fit ​​block is exactly at the same horizontal line as the first and second slots. The snap-fit ​​block is inserted into the first and second slots to limit the annular baffle and the upper module. Then, the hydraulic telescopic rod drives the lower pressure rod to move upward. At this time, the device box rotates to the top of the cooling plate but is not completely cooled. The liquid in the storage chamber will gradually cool down and contract until it is completely cooled down when it rotates to the storage and retrieval position. The air pressure in the sliding groove decreases, and the first tension spring pulls the snap-fit ​​block back to release the insertion of the first and second slots. The upper module can then be moved upward and reset by the elastic force of the first spring. At the same time, the second spring lifts the lower module, causing the molded sealing gasket above the lower module to be ejected upward, completing the discharge.

[0016] 2. The silicone rubber sealing gasket hot pressing molding equipment provided by this invention, when the drive rod moves upward, the drive block slides upward in the vertical groove, and at the top position, it pushes the rotating plate upward and slides to the top of the vertical groove. Afterward, the rotating plate rotates in the opposite direction to reset, blocking the path for the drive block to slide downward, so that the drive block can only enter the inclined groove when sliding down. When the drive block slides to the bottom of the inclined tooth, it similarly pushes the rotating plate, and when it reaches the bottom of the inclined groove, the rotating plate rotates in the opposite direction to reset, preventing the drive block from entering the inclined groove when moving upward. Afterward, the drive block can only slide upward through the vertical groove. This repetition ensures that only the drive ring is driven during each lifting and lowering of the drive block. A unidirectional rotation is performed to set an angle, compressing the spring. When the lower pressure rod moves upward, it is connected to the mounting bracket. At this time, the compressed spring cannot drive the rotating ring and rotating disk to rotate. The limiting effect on the rotating disk is released after the lower pressure rod leaves the mounting bracket. At this time, the spring drives the rotating ring to rotate, causing the rotating disk to drive the device box to rotate by a set angle. Then, the limiting block is inserted into the next set of limiting slots to prevent the rotating ring from rotating too much. By repeating this process, the rotating disk can be driven to rotate by a set angle after each lifting and lowering of the lower pressure rod for hot pressing. This allows the next set of device boxes containing raw materials to be hot pressed to rotate into the hot pressing area for hot pressing operation. Attached Figure Description

A second slot 33 is provided on the side of the upper module 11. The snap-fit ​​block 27 can be inserted into the first slot 32 and the second slot 33.

[0034] The rotating mechanism 8 includes a spring 34 fixedly installed on the outer wall of the drive ring 9. The outer side of the spring 34 is fixedly connected to the inner wall of the rotating ring 4. The drive ring 9 is provided with a drive component 35 for rotating the drive ring 9 by a set angle when the connecting rod 22 is raised or lowered. The base 1 is provided with a control component 36 for controlling the rotating ring 4 to rotate by a set angle each time.

[0035] The driving component 35 includes a driving rod 37 fixedly installed at the bottom of the connecting rod 22. The driving rod 37 is slidably connected to the outer wall of the hydraulic telescopic rod 3. A driving block 38 is fixedly connected to the driving rod 37. The inner wall of the driving ring 9 has multiple sets of vertically distributed vertical grooves 39 at equal intervals. The inner wall of the driving ring 9 has multiple sets of inclined grooves 40 at equal intervals. The lower end and upper end of the inclined groove 40 are respectively connected to two adjacent sets of vertical grooves 39. The driving block 38 is slidably connected to both the vertical grooves 39 and the inclined grooves 40. A rotating plate 41 is rotatably connected to the upper side of the vertical groove 39 and the lower side of the inclined groove 40. The rotation position of the rotating plate 41 is connected to the spring shaft to ensure that one end of the rotating plate 41 is always biased to one side for contact.

[0036] The control component 36 includes a limiting block 42. The side of the rotating ring 4 has multiple limiting grooves 43 that are inserted into the limiting block 42. The top side of the limiting block 42 is arc-shaped, which only serves to initially limit the movement and will not jam the rotating ring 4. The base 1 has a guide groove 44. The limiting block 42 is slidably connected to the guide groove 44. One end of the limiting block 42 is fixedly connected to a third spring 45 that is fixedly connected to the guide groove 44.

[0037] The temperature regulating mechanism 10 includes a cooling plate 46 and a heating plate 47 fixedly installed on the base 1. Both the cooling plate 46 and the heating plate 47 are semi-circular arc-shaped, and the bottom surface of the rotating disk 5 is rotatably connected to the top surface of the cooling plate 46 and the heating plate 47.

[0038] The molding sealing gasket on the lower module 17 is removed by loading / unloading equipment (not shown) or manually at the storage point, and an appropriate amount of raw material to be processed is placed on it. The hydraulic telescopic rod 3 is activated. When the hydraulic telescopic rod 3 moves downward, it drives the connecting rod 22 to move downward, so that the lower pressing rod 23 moves downward and inserts into the mounting bracket 12 and pushes the upper module 11 downward. During the downward movement of the upper module 11, the lifting block 14 slides down in the lifting groove 13, the first spring 15 is compressed, and at the same time the pushing rod 25 moves downward to push the gas in the sleeve 26 downward into the bottom end of the annular groove 21, thereby pushing the annular baffle 20 to slide upward in the annular groove 21, blocking the side of the lower module 17, so that the raw material is in a state of being surrounded. As the upper module 11 moves downward, it squeezes the raw material heated by the addition plate to heat-press the silicone rubber raw material into the specified shape. At the same time, the lower module 17 moves down to the lowest end. At this time, due to the high temperature of the device box 7, the liquid temperature below the lifting plate 31 will rise and expand, pushing the lifting plate 31 upward, thus lifting the lifting block 14. Gas or liquid above plate 31 is pushed into sliding groove 29, causing snap-fit ​​block 27 to push down to one side of module 17. At this time, due to the upward movement of annular baffle 20 and downward movement of upper module 11, one end of snap-fit ​​block 27 is exactly at the same horizontal line as the first slot 32 and the second slot 33. Snap-fit ​​block 27 is inserted into the first slot 32 and the second slot 33 to limit the annular baffle 20 and upper module 11. After that, hydraulic telescopic rod 3 drives the downward pressure rod 23 to move upward. At this time, device box 7 rotates to the top of cooling plate 46 and is not completely cooled. The liquid in storage chamber 28 will gradually cool down and shrink until it is completely cooled after multiple rotations to the storage and retrieval position. The air pressure in sliding groove 29 decreases, and the first tension spring 30 pulls snap-fit ​​block 27 back to release the insertion of first slot 32 and second slot 33. Upper module 11 can then be moved upward and reset by the elastic force of first spring 15. At the same time, second spring 16 lifts lower module 17, causing the molded sealing gasket above lower module 17 to be ejected upward, completing the discharge.

[0039] During the lifting and lowering of the connecting rod 22, the hydraulic telescopic rod 3 also drives the drive rod 37 to lift and lower. When the drive rod 37 moves upward, the drive block 38 slides upward in the vertical groove 39 and slides to the top of the vertical groove 39 after pushing the rotating plate 41 upward at the top position. After that, the rotating plate 41 rotates in the opposite direction to reset, blocking the path for the drive block 38 to slide down. This ensures that the drive block 38 can only enter the inclined groove 40 when it slides down. When the drive block 38 slides to the bottom of the inclined tooth, it also pushes the rotating plate 41. When it reaches the bottom of the inclined groove 40, the rotating plate 41 rotates in the opposite direction to reset, preventing the drive block 38 from entering the inclined groove 40 when it moves upward. After that, the drive block 38 can only slide upward through the vertical groove 39. This process repeats to ensure that the drive block 38 can only slide upward during the lifting and lowering process. The drive ring 9 is rotated unidirectionally to a set angle, causing the spring 34 to compress. When the lower pressure rod 23 moves upward, it is connected to the mounting bracket 12. At this time, the spring 34 is compressed and cannot drive the rotating ring 4 and the rotating disk 5 to rotate. The limit on the rotating disk 5 is released after the lower pressure rod 23 leaves the mounting bracket 12. At this time, the spring 34 drives the rotating ring 4 to rotate, causing the rotating disk 5 to drive the device box 7 to rotate at a set angle. The limit block 42 is inserted into the next set of limit slots 43 to prevent the rotating ring 4 from rotating too much. By repeating this process, the rotating disk 5 can be driven to rotate at a set angle after each lifting and lowering of the lower pressure rod 23 for hot pressing, so that the next set of device boxes 7 containing raw materials to be hot pressed can rotate to the hot pressing area for hot pressing operation.

[0040] It is worth noting that the top of the limiting block 42 only acts as a stop against the limiting groove 43. When the spring 34 has a large rebound force, it will drive the rotating ring 4 to rotate, causing the limiting block 42 to slide out of the limiting groove 43. The limiting block 42 will continue to be inserted into the next limiting groove 43 after the rotating ring 4 rotates to a set angle to complete the limiting. The cooling plate 46 can cool down the half of the device box 7 after hot pressing until it reaches the storage position, at which point the cooling is complete and the sealing gasket is ejected. After that, the raw material is placed on it and rotated to the top of the heating plate 47 for preheating. When it reaches the hot pressing area, the heating reaches the highest temperature, at which point the hot pressing operation can be performed.
