Description

Technical Field

[0001] This utility model relates to a vulcanized capsule and tooling for air spring bladders, belonging to the field of vulcanized capsules. Background Technology

[0002] With the rapid development of the automotive industry, customers have increasingly higher requirements for the comfort and handling of vehicles. Air springs, using air as the damping cutoff, can achieve very low stiffness and provide a level of comfort superior to coil springs. The bladder, a crucial component of air springs, requires a vulcanized bladder as an inner mold for vulcanization due to its unique structure.

[0003] The main function of the vulcanizing bladder is to be filled with high-pressure nitrogen or steam during the vulcanization process, causing it to expand and stretch the pre-formed bladder skin to fit against the inner surface of the mold, thus creating the appropriate vulcanization pressure. The vulcanizing bladder is the most crucial component ensuring the integrity of the air spring's bladder skin. The structure and service life of the vulcanizing bladder directly affect the vulcanization quality and efficiency of the air spring. Summary of the Invention

An upper clamping edge is provided at the upper port of the vulcanized capsule, and a lower clamping edge is provided at the lower port of the vulcanized capsule. The upper clamping edge faces the inside of the port, and the lower clamping edge faces the outside of the port. The upper and lower ends of the upper clamping edge protrude outward to form an upper clamping edge sealing surface, and the upper and lower ends of the lower clamping edge protrude outward to form a lower clamping edge sealing groove and a lower clamping edge sealing surface.

[0025] like Figure 1 A vulcanized capsule for air spring bladders includes a vulcanized capsule 3, which is a hollow structure. The upper port of the vulcanized capsule 3 is provided with an upper clamping edge 3-1, and the lower port of the vulcanized capsule 3 is provided with a lower clamping edge 3-5. The upper clamping edge 3-1 faces the inside of the port, and the lower clamping edge 3-5 faces the outside of the port.

[0026] The sulphurized capsule 3 is divided into three sections: an upper expanding working surface 3-2, a middle expanding working surface 3-3, and a lower expanding working surface 3-4. The upper expanding working surface 3-2 has the same inner diameter, the middle expanding working surface 3-3 has an inner diameter that gradually increases from top to bottom, and the lower expanding working surface 3-4 has the same inner diameter.

[0027] Example 2

[0028] like Figures 2 to 4A vulcanizing device for air spring bladders includes a vulcanized bladder 3 as described in Embodiment 1, as well as an upper cover 1, a central rod 2, a holding device 4, and a fixing device 5. The upper ends of the upper cover 1 and the central rod 2 cooperate with the upper clamping edge 3-1 to seal and limit the upper end of the vulcanized bladder 3. The central rod 2 penetrates the interior of the vulcanized bladder 3 and its lower end is connected to the fixing device 5. The holding device 4 and the fixing device 5 cooperate with the lower clamping edge 3-5 to seal and limit the lower end of the vulcanized bladder 3, thereby forming a sealed cavity inside the vulcanized bladder 3.

[0029] In this embodiment, the lower end face of the upper cover 1 and the upper end face of the central rod 2 are respectively provided with an upper cover sealing groove 1-1 and a central rod sealing groove 2-1, which respectively cooperate with the two upper flange sealing surfaces. The upper cover 1 and the central rod 2 are fixedly connected by bolts.

[0030] In this embodiment, the front end of the central rod 2 is provided with a central rod connector 2-2, which is engaged and locked with a threaded hole 5-4 opened on the fixing device 5.

[0031] In this embodiment, the fixing device 5 is provided with an air intake channel 5-1, which is connected to the internal cavity of the vulcanizing capsule 3.

[0032] In this embodiment, the clamping device 4 is provided with a first clamping sealing surface 4-2, a second clamping sealing surface 4-3, and a clamping sealing groove 4-1. The first clamping sealing surface 4-2 and the second clamping sealing surface 4-3 are located on both sides of the clamping sealing groove 4-1. The fixing device 5 is provided with a fixing sealing groove 5-3 and a fixing mating surface 5-2. The fixing sealing groove 5-3 and the clamping sealing groove 4-1 respectively mate with the two lower clamping edge sealing surfaces.

[0033] In this embodiment, the clamping device 4 and the fixing device 5 are fixedly connected by bolts.

[0034] The working principle of this fixture is as follows: The upper cover sealing groove 1-1 of the upper cover mates with the sealing surface A3-1-1 of the upper clamping edge of the vulcanizing capsule; the central rod sealing groove 2-1 of the central rod mates with the sealing surface B3-1-2 of the upper clamping edge of the vulcanizing capsule; the upper cover 1, central rod 2, and upper clamping edge 3-1 work together to seal and limit the upper end of the vulcanizing capsule. The first sealing surface 4-2 mates with the sealing groove 3-5-1 of the lower clamping edge; the sealing groove 4-1 mates with the sealing surface A of the lower clamping edge; and the sealing surface B3-5-3 of the lower clamping edge mates with the fixing sealing groove 5-3; all these work together to seal and limit the lower end of the vulcanizing capsule. The second sealing surface 4-3 is fastened to the fixing device by bolts and the fixing mating surface 5-2, limiting the position of the fixing device. Then, the central rod connector 2-2 mates with the threaded hole 5-4 to lock, limiting the position of the central rod. In summary, the vulcanizing capsule and various tooling components form a sealed space. During vulcanization, high-pressure gas is introduced through the air inlet channel 5-1, causing the expanded working surface to expand and adhere the inserted empty spring capsule blank to the inner wall of the molding die, thus achieving product molding and vulcanization. After vulcanization, the high-pressure lifting is completed, and the gas is discharged through the air inlet channel, allowing the empty spring capsule to be removed.

Those skilled in the art should understand that the above embodiments do not limit the scope of protection of this utility model in any way, and all technical solutions obtained by equivalent substitution or other means fall within the scope of protection of this utility model. Parts not covered by this utility model are the same as or can be implemented using existing technology.
