An air spring vulcanizing device

Abstract

The invention discloses an air spring vulcanizing device, which includes an upper and a lower clamp plate and an outer cylinder that can be detachably connected, wherein, the outer cylinder is provided with an inner cylinder, an annular enclosed vulcanization cavity is formed between the inner and outer cylinders, a two-terminal positioning vulcanized rubber sheath and a vulcanization drum sheathed on the inner cylinder is provided in the vulcanization cavity, vulcanized air spring capsule coats outside the vulcanization drum, which has features that the inner and outer cylinders are respectively wrapped with electric heating chips which are controlled by a circuit control system for controlling the heating temperature, the vulcanization pressure is provided by high-pressure compressed air, the air spring capsule is vulcanized and molded under the control of heating temperature and pressure conditions. The vulcanizing device has advantages of high thermal efficiency, fast curing speed, large vulcanization pressure, low temperature in the vulcanization process, high producing efficiency, simple equipment, stable product dimensions, and high pass rate.

Description

technical field [0001] The invention relates to a vulcanizing device for a one-time molding rubber product, in particular to a one-time molding air spring vulcanizing device. Background technique [0002] Air spring is a kind of anti-vibration and shock-absorbing parts used for vehicle seats to keep the seat state stable, reduce the impact of the vehicle's bumps and vibrations caused by sudden force on the driver, and improve the seat's comfort and anti-overturning performance. To improve the protection of the human body, the air spring adopts an air bag made of elastic material and fabric material and stores compressed air. The airbag frame material is made of polyethylene terephthalate fiber cord fabric with high modulus and low shrinkage and vulcanized chloroprene copolymer rubber. The production process of the existing rubber air spring adopts the production process of tires, and its process includes raw collagen material inspection, mixing, sheeting, calendering, moldi...
