Description

Technical Field

[0001] The invention relates to the technical field of rubber sealing ring production, in particular to a flat plate vulcanizing machine for producing rubber sealing rings and a vulcanizing method thereof. Background Art

[0002] As an important sealing element, rubber sealing rings are widely used in many fields such as machinery, automobiles, aerospace, etc. In the production process of rubber sealing rings, the flat plate vulcanizer is one of the key equipment. The traditional flat plate vulcanizer plays an important role in the production of rubber sealing rings. However, with the continuous growth of market demand and higher requirements for production efficiency, it has gradually exposed some significant shortcomings in the loading and unloading links, which seriously affects the overall processing efficiency. At present, most flat plate vulcanizers mainly rely on manual operation when unloading. Workers need to manually take out the finished products after vulcanization is completed. This manual unloading method is not only labor-intensive, but also slow in operation. Human errors are prone to occur, resulting in unstable production rhythm. In addition, due to the limitations of manual operation, the time interval in the unloading process is difficult to accurately control, resulting in a lot of idle waiting time when the flat-plate vulcanizer is working, and continuous and efficient production cannot be achieved. This not only reduces the effective utilization rate of the equipment, but also increases production costs. At the same time, in some flat-plate vulcanizers with a slightly higher degree of automation, although simple mechanical conveying devices are used for unloading, these devices often have problems such as poor flexibility and insufficient adaptability, and cannot meet the rapid unloading requirements of rubber sealing rings of different specifications and shapes, so in actual applications, it is still impossible to effectively improve processing efficiency.

[0045] The movable connector 4 is located directly above the fixed connector 10, and an air supply connector is provided on the upper side surface of the movable connector 4. The supporting plate 5 is of arc-shaped design, and the upper surface of the supporting plate 5 fits the lower surface of the lower mold 9.

[0046] The limiting plate 13 is located on the side of the angle gear 14 facing the lower die 9, and the limiting plate 13 and the angle gear 14 are concentrically arranged;

[0047] The adjusting gear rod 16 is of arc-shaped design, and the adjusting gear rod 16 is meshed and connected with the angle gear 14, and the adjusting gear rod 16 is located on the side of the angle gear 14 facing the center of the functional plate 6;

[0048] The positioning rod 17 is slidably connected to the mounting ring 7, and one end of the positioning rod 17 is engaged with the limit plate 13, and the end of the positioning rod 17 engaged with the limit plate 13 is an isosceles trapezoidal design, and a spring is connected between the positioning rod 17 and the mounting ring 7;

[0049] The rotating plate 19 is slidably connected to the upper die 8, and a spring is connected between the rotating plate 19 and the upper die 8, a spring is connected between the upper die 8 and the lower die 9, a spring is connected between the sliding seat 20 and the anti-rotation plate 21, and one end of the anti-rotation plate 21 is in contact with the upper surface of one end of the upper die 8;

[0050] During the vulcanization process, the anti-rotation plate 21 facing the adjusting gear rod 16 is pulled, and the anti-rotation plate 21 slides relative to the sliding seat 20 to stretch the spring between the sliding seat 20, so that the anti-rotation plate 21 releases the limit on one end of the upper mold 8, so that the upper mold 8 can be opened and rotated. At this time, the operator puts the raw material into the material trough of the lower mold 9, and then rotates and closes the upper mold 8 and releases the anti-rotation plate 21, so that the anti-rotation plate 21 restores the limit on the upper mold 8, and then starts the central motor 11 on the side surface of the mounting plate 2, and the central motor 11 drives the mounting ring 7 to rotate relative to the functional plate 6, so that the material to be vulcanized is placed in the lower mold 9. The mounting ring 7 and the upper die 8 of the material can rotate to the support plate 5 to obtain the support of the support plate 5. In the process of the mounting ring 7 and the upper die 8 making circular motions, the angle gear 14 rotates by meshing with the adjusting gear rod 16, and the angle gear 14 drives the upper die 8 and the lower die 9 to rotate through the rotary rod 12, thereby ensuring that the upper die 8 and the lower die 9 can keep the fixed connector 10 facing upward when they move to the top of the mounting ring 7, so as to achieve the purpose of driving the movable connector 4 to engage with the fixed connector 10 through the hydraulic rod 3 to inject the heating medium and extrude the upper die 8 and the lower die 9;

[0051] After the vulcanization of the rubber sealing ring between the upper mold 8 and the lower mold 9 is completed, the hydraulic rod 3 drives the movable connecting head 4 to move up and disengage from the clamping connection with the fixed connecting head 10. At this time, the central motor 11 drives the mounting ring 7 to rotate so that the upper mold 8 and the lower mold 9 are driven to rotate until the upper mold 8 and the lower mold 9 with the vulcanized rubber sealing ring are driven to the bottom of the functional plate 6. At this time, the electromagnet 18 is energized when it rotates to the bottom through the setting of a predetermined control program, so that the electromagnet 18 can adsorb the anti-rotation plate 21 so that the anti-rotation plate 21 slides to release the limit on the upper mold 8, so that the upper mold 8 passes through under the action of gravity. The rotating plate 19 flips downward relative to the lower die 9 for automatic discharge, and when the upper die 8 and the lower die 9 gradually rotate to a horizontal state, the electromagnet 18 is powered off through the setting of a predetermined control program. At this time, the anti-rotation plate 21 squeezes the upper die 8 under the support of the spring between the sliding seat 20, so that the upper die 8 gradually rotates and closes with the lower die 9. After the angle gear 14 disengages from the adjusting gear rod 16, the mounting ring 7 supports the positioning rod 17 through the spring between the positioning rod 17 and the positioning groove 15 to engage with the limit plate 13, so that the upper die 8 and the lower die 9 can maintain a stable vertical or horizontal state.

[0052] Embodiment 2: Based on Embodiment 1, this embodiment discloses that an automatic discharging mechanism is provided on the upper surface of the base 1, and the vulcanized rubber sealing ring can be automatically discharged by rotating the upper mold 8 to the bottom and then automatically flipping open. The automatic discharging mechanism includes: a sliding rod 22, the sliding rod 22 is fixedly arranged on the upper surface of the base 1, and a rotating displacement rod 23 is installed on the upper surface of the base 1, and a driving motor 24 is fixedly installed on the side surface of one end of the base 1, and a discharging brush 25 is installed on the outer surfaces of the sliding rod 22 and the displacement rod 23, and a support seat 26 is fixedly arranged on the upper surface of one end of the base 1, and a discharging groove 27 is opened on the upper surface of the base 1 on one side of the support seat 26;

[0053] The sliding rod 22 is slidably connected to the material removal brush 25, and the outer surface of the material removal brush 25 facing the upper mold 8 is evenly provided with bristles, the displacement rod 23 is threadedly connected to the material removal brush 25, and the rotating shaft of the displacement rod 23 is fixedly connected to the output shaft of the driving motor 24, the upper end of the support seat 26 is inclined, and the upper end side surface of the support seat 26 is in contact with the outer surface of the upper mold 8;

[0054] When the upper mold 8 rotates to the bottom and flips downward, the outer surface of the lower end of the upper mold 8 fits with the upper side surface of the support seat 26, and then the drive motor 24 is started. The drive motor 24 drives the displacement rod 23 to rotate so that the displacement rod 23 drives the discharge brush 25 to slide on the sliding rod 22 through the threaded connection with the discharge brush 25. During the sliding process, the discharge brush 25 discharges the rubber sealing ring through the contact friction between the bristles on the surface and the rubber sealing ring inside the upper mold 8. The rubber sealing ring taken away from the upper mold 8 falls downward and is collected through the discharge groove 27 on the surface of the base 1.
