Hydraulic rotary joints are mainly a general term for fluid medium rotary joints such as oil, water, and chemical agents. They are widely used in engineering hydraulic machinery and plastic molding industries. In hydraulic engineering machinery, they mainly transmit hydraulic oil, which is the hydraulic power for equipment power. In the injection molding machine industry, cooling water can be provided alone, or cooling water and hydraulic oil can be provided at the same time. The hydraulic rotary joint is mainly used in the vertical injection molding machine in the injection molding machine industry. It is widely used in 160T and 200T injection molding machines. It is mainly used for the support shaft of the injection molding machine. When the hydraulic rotary joint is installed in the injection molding machine, it is very troublesome to disassemble, so the requirements for product quality are very high. Some special injection molding machines require a hydraulic rotary joint with two through holes. It is used to cross the double shaft cylinder shaft.
The hydraulic rotary joint is also called the water-passing rotary head in the injection molding machine industry. In fact, the incoming water is mainly used to cool the mold, speed up the production efficiency, and improve the product. The model matches different types of hydraulic rotary joints, adopts U-shaped notch connection, drives the entire casing to rotate through the stop, and the mandrel is locked by long bolts. It is a relatively special hydraulic rotary joint product. Water-type design, multiple through holes for water outlet, meet the requirements of multi-station injection molding machine, widely used in various types of injection molding machine equipment.
