The upper end of the pipeline main (P,T,P) is the executive loop system, and the lower end is the main loop system and the auxiliary loop system. Drive ring system: mainly composed of each drive mechanism (cylinder) and command and control device (main control valve). Its function is to enter the high pressure oil into the vertical two-color injection molding machine pipeline P into the left and right cavities of the cylinder according to the program, and push the oil rod to complete the action. Electromagnetic directional valve is used to realize the time, order and position of high pressure oil intake.
The electromagnetic solenoid valve transmits its working instructions to the solenoid valve through the telecommunication number, and the solenoid valve controls its spool action, infuses the high-pressure oil of the control oil circuit (P) into the high-pressure oil of the control oil circuit (P), and connects the high-pressure oil to the solenoid valve. Main loop system: including power supply and control module; The oil pressure (P) and flow rate (Q) generated by the power source system (motor, oil pump) are composed of the command (CU) and control (CM) modules (pressure valves, laser valves, etc.).
The high-pressure oil sent by the pump, the time of entering the main road, the sequence, the pressure and the flow rate, the vertical disc injection molding machine are all through a flow valve, the pressure valve obtained by the electromagnet, indicating the time, the sequence, the strength, the strength, the strength, the strength, the pressure, the flow rate, the pressure of the spool and the opening. A "network" is formed between the executive circuit and the main circuit through the inlet pipe P(high pressure), the return pipe T(low pressure) and the control loop P(high pressure).
