Rubber joint

Rubber joint is also called rubber flexible joint, rubber joint, rubber soft joint, rubber shock absorber, etc. It belongs to a kind of flexible connection. It is made of rubber sphere and inner and outer rubber layer, cord fabric and steel wire frame as reinforcement. It is a new kind of flexible connection device for transporting various media. It is a kind of high elasticity, high air tightness, medium resistant and weather resistant pipe joint. It can reduce the vibration, noise, and displacement caused by the change of pressure and the deformation of the pipeline. It is widely used in chemical industry, construction, water supply, drainage, oil, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, power and aviation.
The rubber joint mold is mainly composed of upper mold, lower mold, parallel strip, positioning pin, inner core, and other components. The mold is opened and closed by the action of the upper mold and the lower mold. When opening or closing the mold, a parallel strip is provided on one of the upper or lower molds, and a positioning pin is provided on the other mold.
The mold design principle of rubber joint is to determine the main parameters such as the size, shape, and structure of the rubber joint according to the shape, size, and technical requirements of the final product. In the design process, the mold structure, parting surface, mold core pulling, and ejector system of the mold should be fully considered to ensure the quality of the product. The mold structure should be easy to process, manufacture, and assemble.
In the rubber joint molding process, the rubber raw material is firstly plasticized and heated in the rubber joint mold to maintain its shape and size. The plasticizing process is crucial as it determines the final product's performance. A well-designed and manufactured mold can greatly reduce defects and improve the quality and efficiency of the rubber joint production. Regardless of the complexity of the rubber joint design, a well-designed mold can result in an efficient and accurate manufacturing process.
In summary, the mold for rubber joints is an essential tool in the production process, which needs to be designed and manufactured with precise craftsmanship to meet the technical requirements for producing high-quality rubber joints.
