Description

Technical Field

[0001] This invention relates to the field of vulcanization equipment technology, specifically to a vulcanization device for rubber tire processing. Background Technology

[0002] In industrial production, vulcanization is commonly used to improve the overall hardness of certain materials. Taking tire vulcanization as an example, this process refers to the vulcanization of the outer tire, typically achieved through a mold-pressurization method. Before vulcanization, the tire is a viscoelastic, malleable rubber, easily deformable, with low strength, and unusable. Through vulcanization, the malleable rubber solidifies and transforms into a highly elastic rubber with usable value. Tire vulcanization equipment mainly consists of a mold and a central mechanism. The mold determines the tire tread pattern, while the central mechanism is responsible for filling and shaping the bladder. After the mold closes, the bladder is filled with a heat medium. Once the tire is shaped, it enters the vulcanization stage, ultimately achieving the transformation from malleable rubber to highly elastic rubber.

[0003] Existing tire vulcanizing equipment has gradually revealed its shortcomings during use, mainly in the following aspects:

[0004] The bladder replacement process is complex. Specifically, during tire vulcanization, the bladder is filled with a heat medium, which serves two purposes: shaping the tire and completing the vulcanization process. In the initial preparation stage, the central mechanism vertically stretches the bladder to prevent interference during tire loading. After tire loading, the central mechanism resets the bladder, ensuring it is fully inside the tire. The bladder is then filled with a heat medium, extending and pressing against the tire's interior. After the mold closes, the tire is shaped and vulcanized. After vulcanization, the bladder needs to be vertically stretched again to avoid the tire. Because the bladder is easily damaged by repeated stretching and contraction at high temperatures, its airtightness is crucial. Both ends of the bladder are clamped and fixed to the central mechanism. The upper fixed side is directly exposed, while the lower fixed side, which needs to cooperate with the lower mold to form the tire side-shaping structure, is located inside the lower mold. Therefore, replacing the bladder requires completely removing the lower mold, making the process extremely cumbersome.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a vulcanization equipment for rubber tire processing. This equipment enables rapid replacement of the bladder without disassembling the mold, significantly improving the practicality and convenience of the equipment.

[0007] To address the above problems, the present invention provides the following technical solution:

[0008] A vulcanizing device for rubber tire processing includes a base, a supporting circular plate fixedly mounted on the top of the base, an upper connector and a lower connector arranged vertically on the top of the supporting circular plate, the upper connector being vertically movable, a capsule being provided between the upper and lower connectors, the upper and lower openings of the capsule correspondingly clamping the upper and lower connectors, a plurality of sliding arc-shaped plates arranged circumferentially along the top of the supporting circular plate, each sliding arc-shaped plate having a cavity at its top, the plurality of sliding arc-shaped plates limiting the lower connector when they slide to abut against each other, a plurality of hollow fixing blocks being provided at the bottom of the upper connector, sliding blocks being slidably mounted on the inner wall of each hollow fixing block, and a plurality of fixing columns being provided at the top of the lower connector, the upper and lower connectors being able to be quickly connected and separated through the sliding blocks and fixing columns.

[0009] As an optimized solution, the fixed column is divided into a spherical structure, a column structure and a boss structure from top to bottom. A reset ring is slidably sleeved on the column structure. The top and bottom surfaces of the reset ring are both inclined surfaces. The edge of the reset ring protrudes from the edge of the spherical structure. The bottom of the spherical structure is provided with a clearance groove to avoid the reset ring.

[0010] As an optimized solution, the upper side of one end of the sliding block is an inclined surface and the lower side is an arc surface. A limiting rod is fixedly provided at the end of the sliding block. The limiting rod passes through the hollow fixed block and is slidably connected to it. A compression spring is sleeved on the limiting rod, and the two ends of the compression spring abut against the sliding block and the hollow fixed block respectively.

[0011] As an optimized solution, the upper connecting member includes an upper clamping plate and an upper pressure plate, and the lower connecting member includes a lower clamping plate and a lower pressure plate. The upper clamping plate and the upper pressure plate, as well as the lower clamping plate and the lower pressure plate, are detachably connected by fastening bolts. The hollow fixing block is fixedly connected to the upper clamping plate, and the fixing column is fixedly connected to the lower clamping plate. The upper opening of the capsule is clamped between the upper clamping plate and the upper pressure plate, and the lower opening of the capsule is clamped between the lower clamping plate and the lower pressure plate.

[0012] The inner wall of the sliding arc plate is fixedly provided with a limiting ring, and the peripheral wall of the lower pressure plate is provided with a limiting groove. The limiting groove and the limiting ring are set in accordance with the shape.

[0013] As an optimized solution, the bottom of the upper clamping plate is fixedly provided with several positioning posts, and the top of the lower clamping plate is fixedly provided with several positioning cylinders.

[0014] As an optimized solution, a lifting shaft is provided through the top of the supporting circular plate. The top end of the lifting shaft passes through the lower pressure plate and the lower clamping plate and is fixedly connected to the upper clamping plate. A hydraulic push rod is fixedly provided on the top of the base. The telescopic end of the hydraulic push rod is fixedly connected to the lifting shaft. The lower clamping plate and the lower pressure plate are both slidably and sealingly connected to the lifting shaft.

[0015] As an optimized solution, the lifting shaft is provided with an air intake channel and an air exhaust channel inside, and the outer wall of the lifting shaft is provided with an air exhaust port and an air intake port arranged vertically. The air intake port is connected to the air intake channel, and the air exhaust port is connected to the air exhaust channel.

[0016] As an optimized solution, the lower clamping plate is provided with a guide plate at its top, and the fixing column and positioning cylinder both pass through the guide plate and are fixedly connected to it, and the lifting shaft is in frictional contact with the guide plate.

[0017] As an optimized solution, a plurality of drive telescopic cylinders are fixedly provided at the bottom of the supporting circular plate, and the telescopic ends of the drive telescopic cylinders are fixedly connected to the sliding arc plate.

[0018] As an optimized solution, a fixed crossbeam is provided above the base, and the fixed crossbeam is fixedly connected to the base through a support frame. An upper mold assembly is provided at the bottom of the fixed crossbeam. The upper mold assembly includes an upper module. A hydraulic push cylinder is provided on the fixed crossbeam. The upper module is slidably connected to the support frame. The telescopic end of the hydraulic push cylinder is fixedly connected to the upper module. An upper mold cavity is provided at the bottom of the upper module. An array of opening and closing molds is provided inside the upper mold cavity.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. When replacing the capsule, the lifting shaft moves downwards. When the sliding block contacts the spherical structure of the fixed column, it slides inwards, compressing the spring. When the sliding block disengages from the spherical structure, it resets with the help of the compression spring (e.g., Figure 9 As shown), at this time, the upper clamping plate and the lower clamping plate are connected, and the sliding arc plate slides outward, thereby releasing the restriction on the lower pressure plate. The lifting shaft moves upward, thereby driving the upper pressure plate and the lower pressure plate to move upward. The capsule is lifted, and the bottom of the lower pressure plate is exposed, thus enabling quick capsule replacement. After the capsule is replaced, the lifting shaft drives the lower pressure plate to reset, and the sliding arc plate resets to limit the lower pressure plate. Then, the upper clamping plate continues to move downward, and the sliding block contacts the top surface of the reset ring and slides inward. The sliding block moves downward to below the reset ring, and the upper clamping plate moves upward. The sliding block drives the reset ring to slide upward. After the reset ring enters the clearance groove, it is limited. When the sliding block moves upward, it contacts the bottom surface of the reset ring and slides inward. When the end of the sliding block contacts the edge of the reset ring, part of the sliding block faces the spherical structure (as shown). Figure 10 As shown), after the sliding block separates from the reset ring, the reset ring resets under the action of gravity, and the sliding block contacts the spherical structure under the cooperation of the compression spring. The upper clamping plate continues to rise until it is reset, and the upper clamping plate and the lower clamping plate are separated. This equipment can realize the quick replacement of capsules without disassembling the mold, which significantly improves the practicality and convenience of the equipment.

[0021] 2. When the sliding block moves to the lower position of the spherical structure, the positioning pin is inserted into the positioning cylinder. The positioning pin and positioning cylinder can prevent the lower clamping plate and lower pressure plate from moving circumferentially when the bladder is disassembled and installed, thereby preventing the bladder from twisting and wrinkling, which would affect the tire's shape.

[0022] 3. The baffle plate prevents short-circuit flow of the heat medium inside the capsule, ensuring uniform temperature distribution inside the tire.

[0023] 4. The lower side of the end of the sliding block is set as an arc surface. When the sliding block moves downward, the arc surface contacts the spherical structure and the upper inclined surface of the reset ring in sequence, thereby driving the sliding block to slide inward. The upper side of the end of the sliding block is set as an inclined surface. When the sliding block moves upward, the inclined surface contacts the lower inclined surface of the reset ring, similarly driving the sliding block to slide inward. The reset ring can be limited by the boss structure. Attached Figure Description

[0041] A limiting ring 22 is fixedly provided on the inner wall of the sliding arc plate 9, and a limiting groove 11 is provided on the periphery of the lower pressure plate 21. The limiting groove 11 and the limiting ring 22 are set in accordance with each other.

[0042] Several positioning posts 18 are fixedly provided at the bottom of the upper clamping plate 17, and several positioning cylinders 14 are fixedly provided at the top of the lower clamping plate 13.

[0043] A lifting shaft 15 is provided through the top of the supporting circular plate 8. The top of the lifting shaft 15 passes through the lower pressure plate 21 and the lower clamping plate 13 and is fixedly connected to the upper clamping plate 17. A hydraulic push rod 40 is fixedly provided on the top of the base 1. The telescopic end of the hydraulic push rod 40 is fixedly connected to the lifting shaft 15.

[0044] The lifting shaft 15 has an air intake channel 35 and an exhaust channel 38 inside. The outer wall of the lifting shaft 15 has an exhaust port 37 and an air intake port 36 arranged vertically. The air intake port 36 is connected to the air intake channel 35, and the exhaust port 37 is connected to the exhaust channel 38.

[0045] The top of the lower clamping plate 13 is provided with a guide plate 27. The fixed column 28 and the positioning cylinder 14 both pass through the guide plate 27 and are fixedly connected to it. The lifting shaft 15 is in frictional contact with the guide plate 27.

[0046] Several drive telescopic cylinders 39 are fixedly provided at the bottom of the supporting circular plate 8, and the telescopic ends of the drive telescopic cylinders 39 are fixedly connected to the sliding arc plate 9.

[0047] A fixed crossbeam 4 is provided above the base 1. The fixed crossbeam 4 is fixedly connected to the base 1 through the support frame 2. An upper mold assembly 3 is provided at the bottom of the fixed crossbeam 4. The upper mold assembly 3 includes an upper module 6. A hydraulic push cylinder 5 is provided on the fixed crossbeam 4. The upper module 6 is slidably connected to the support frame 2. The telescopic end of the hydraulic push cylinder 5 is fixedly connected to the upper module 6. An upper mold cavity is provided at the bottom of the upper module 6. An array of opening and closing molds 7 are provided inside the upper mold cavity.

[0048] The structure and principle of the upper mold component 3 are similar to those of existing vulcanizing equipment, and will not be elaborated on here.

[0049] The working principle of this device is as follows:

[0050] The lifting shaft 15 moves upward, the capsule 16 stretches vertically to avoid obstruction, and the tire to be vulcanized is placed through the capsule 16 into the top cavity 10 of the sliding arc plate 9. The lifting shaft 15 returns to its original position, and the capsule 16 is completely inside the tire. The heat medium enters the air intake channel 35 and is discharged into the capsule 16 through the air intake port 36. The capsule 16 expands and comes into contact with the inside of the tire (the above changes of the capsule are as follows). Figure 8 As shown), the upper module 6 moves downward, and after the opening and closing mold 7 abuts against the sliding arc plate 9, the opening and closing mold 7 retracts. After the opening and closing mold 7 retracts, it squeezes and contacts the tire tread and forms tire tread. With the cooperation of the air intake channel 35 and the exhaust channel 38, the circulating heat medium continuously flows through the inside of the capsule 16 to vulcanize the tire. After vulcanization, the circulating heat medium inside the capsule 16 is extracted, the opening and closing mold 7 opens, the upper module 6 resets, the lifting shaft 15 moves upward to avoid stretching the capsule 16, and finally the vulcanized tire is taken out.

[0051] When replacing capsule 16, lifting shaft 15 moves downward, sliding block 25 slides inward when it contacts the spherical structure 32 of fixed column 28, compression spring 31 is compressed, and when sliding block 25 disengages from spherical structure 32, it resets with the cooperation of compression spring 31 (e.g. Figure 9 As shown), at this time, the upper clamping plate 17 and the lower clamping plate 13 are connected, and the sliding arc plate 9 slides outward, thereby releasing the restriction on the lower pressure plate 21. The lifting shaft 15 moves upward, thereby driving the upper pressure plate 19 and the lower pressure plate 21 to move upward. The capsule 16 is lifted, and the bottom of the lower pressure plate 21 is exposed, thus enabling the capsule 16 to be quickly replaced. After the capsule 16 is replaced, the lifting shaft 15 drives the lower pressure plate 21 to reset. The sliding arc plate 9 resets and limits the lower pressure plate 21. Then, the upper clamping plate 17 continues to move downward. The sliding block 25 contacts the top surface of the reset ring 26 and slides inward. The sliding block 25 moves downward to below the reset ring 26. The upper clamping plate 17 moves upward, and the sliding block 25 drives the reset ring 26 to slide upward. The reset ring 26 is limited after entering the relief groove 29. When the sliding block 25 moves upward, it contacts the bottom surface of the reset ring 26 and slides inward. When the end of the sliding block 25 contacts the edge of the reset ring 26, part of the sliding block 25 faces the spherical structure 32 (as shown). Figure 10As shown), after the sliding block 25 separates from the reset ring 26, the reset ring 26 resets under the action of gravity. The sliding block 25 contacts the spherical structure 32 with the cooperation of the compression spring 31. The upper clamping plate 17 continues to rise until it is reset. The upper clamping plate 17 and the lower clamping plate 13 are separated. This device can realize the quick replacement of capsules without disassembling the mold, which significantly improves the practicality and convenience of the device.

[0052] When the sliding block 25 moves to the position below the spherical structure 32, the positioning pin 18 is inserted into the positioning cylinder 14. The positioning pin 18 and the positioning cylinder 14 can prevent the lower clamping plate 13 and the lower pressure plate 21 from moving circumferentially when the capsule 16 is disassembled and installed, thereby preventing the capsule 16 from twisting and wrinkling, which would affect the tire's shape.

[0053] The deflector plate 27 prevents short flow paths from forming when the heat medium flows inside the capsule 16, ensuring uniform temperature distribution inside the tire.

[0054] The lower side of the end of the sliding block 25 is set as an arc surface. When the sliding block 25 moves downward, the arc surface contacts the spherical structure 32 and the upper inclined surface of the reset ring 26 in sequence, thereby driving the sliding block 25 to slide inward. The upper side of the end of the sliding block 25 is set as an inclined surface. When the sliding block 25 moves upward, the inclined surface contacts the lower inclined surface of the reset ring 26, similarly driving the sliding block 25 to slide inward. The reset ring 26 can be limited by the boss structure 34.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
