There are 5 or 6 kinds of solenoid valves on the injection molding machine, collectively referred to as solenoid valves.
The electromagnetic valve of the injection molding machine mainly controls the liquid path, the control of the plexus, and the movement of the curved rod before and after, the mold clamp can be opened and closed in the injection molding machine.
Solenoid valves are automated basic components used to control fluids and are actuators; not limited to hydraulic and pneumatic. Solenoid valves are used to control the direction of hydraulic flow. The mechanical mechanisms of the plant are generally controlled by hydraulic steel, so solenoid valves are used.
The working principle of the solenoid valve has a closed cavity in the solenoid valve. There are through holes at different positions. Each hole leads to a different oil pipe. The middle of the cavity is a valve. On both sides are two electromagnets. Which side of the magnet coil The electric valve body will be attracted to which side, by controlling the movement of the valve body to block or leak different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then pass The pressure of the oil pushes the piston of the oil, and the piston drives the piston rod, which drives the mechanical device. This controls the mechanical motion by controlling the current of the electromagnet.
