Description

Technical Field

[0001] This utility model belongs to the field of air spring vulcanization, specifically an air spring vulcanization device. Background Technology

[0002] With the rapid development of the automotive industry, customers have increasingly higher demands for the comfort and handling of vehicles. Air springs, using air as the damping cutoff, can achieve very low stiffness and provide superior comfort compared to coil springs. The air spring's crucial component, the bladder, requires a vulcanizing bladder as an inner mold for vulcanization due to its unique structure. 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 to fit against the inner surface of the mold, creating appropriate vulcanization pressure. The vulcanizing bladder ensures the most critical link in the air spring bladder's performance. The structure and lifespan of the vulcanizing bladder directly affect the vulcanization quality and efficiency of the air spring.

[0003] In existing vulcanization equipment, the air spring bladder skin is mostly vulcanized using a bladder inflation and shaping method. However, this method results in poor uniformity, and the size of the bladder skin is affected by the inflation pressure.

[0004] In summary, this utility model provides an air spring vulcanizing device to solve the above problems. Utility Model Content

The vulcanizing outer mold includes an outer shell and an inner wall. An outer cavity air chamber is provided between the outer shell and the inner wall. An outer cavity air inlet pipe is connected to one side of the outer shell. The outer cavity air inlet pipe penetrates the outer shell and communicates with the inner wall of the outer cavity air chamber. The vulcanizing inner mold includes an inner mold shell. The inner mold shell has a hollow structure and an air inlet hole is opened at the bottom of the inner mold shell. An upper tooling is installed on the top of the vulcanizing outer mold. A lower tooling is connected to the bottom of the vulcanizing inner mold. An inner cavity air inlet pipe is fixedly connected to the bottom of the lower tooling. The inner cavity air inlet pipe communicates with the vulcanizing inner mold.

[0007] Furthermore, the lower tooling includes a tooling base, the surface of which is provided with an inner mold groove, the middle of which is provided with a connecting air hole, and the bottom of the inner mold shell is fixedly connected to the inner mold groove.
