Rubber injection molding machine production process

Date:2016/8/15 16:40:27

        Rubber injection molding machine is a process and injection molding. The process is plastic pellets or powder placed inside the rubber injection molding machine barrel, after delivery, compression, shear, tensile, mixing, heating and so on, so that the material melted and homogenized, and then by means of a column plug or screw injection pressure is applied to melt the good polymer melt through the nozzle and mold runner system injection locked cryogenic mold, and then through the cooling dwell, stereotypes, open the top of the toilet to give a certain geometry and precision plastic products.
Servo-hydraulic drive and control system 2 rubber injection molding machine configuration
        rubber injection molding machine hydraulic servo drive system principle, rubber injection molding machine hydraulic servo drive and control system mainly by the permanent magnet synchronous servo motor, servo drives, hydraulic pumps, pressure sensors, encoder or resolver constituted. This system offers a new concept of rubber injection molding machine drive and control systems, energy efficiency can be close to all-electric rubber injection molding machine.
        When the system works, rubber injection molding machine machine controller setpoint speed of the machine operation and the pressure is converted into an analog signal or digital signal output to the servo drive, servo drive according to claim command signal to drive the servo motor driven hydraulic pump to work, machine operation speed and pressure control requirements, and speed control and torque control servo motor corresponds. In the rubber injection molding machine process, high pressure clamping and packing process requires pressure control, speed control are the other course of action. When pressure control, pressure servo drive press machine controller gives a control signal to drive the servo motor torque control, hydraulic pump installed in the outlet of the pressure sensor PH pressure output line real-time detection system, the detection signal is fed to the servo drive, machine controllers for a given signal is compared to the immediate correction of the deviation. When the speed control, the speed servo drive press machine controller gives a control signal to drive the servo motor speed control, servo motor or shaft encoder or resolver PG online real-time detection of changes in the angle servo motor operation, the detection signal is fed back to the servo drive operation, and machine controllers for a given signal is compared to the immediate correction of the deviation.
