Application of Hydraulic Rotary Joints in Injection Molding Machines

Hydraulic rotary joints are 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 to provide equipment power and hydraulic power. In the injection molding machine industry, they can provide cooling water separately or simultaneously. Hydraulic rotary joints are mainly used in vertical injection molding machines and are widely used in 160T and 200T injection molding machines. They are designed with through holes, mainly for the support shaft of the injection molding machine. After the hydraulic rotary joint is installed in the injection molding machine, it is very difficult 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 on it. Used for dual axis oil cylinder shafts

Hydraulic rotary joints, also known as over water rotary joints in the injection molding machine industry, are mainly used to cool molds, accelerate production efficiency, and improve products. Some require over mold temperature oil, mainly to provide molding temperature for products. Different types of hydraulic rotary joints are matched according to different models, using U-shaped groove connections to drive the entire outer sleeve to rotate through the stopper. The core shaft is locked by an elongated bolt, making it a relatively special hydraulic rotary joint product. It adopts a water separation design, with multiple through holes for water discharge, meeting the requirements of multiple workstations in injection molding machines,
