The Design of the Injection Molding Machine Control System Based on PLC Controller

Abstract:

Control system of the Plastic injection molding machine formed by electric relays and switching valves has many shortcomings, such as complexity wiring, low control accuracy, inconvenience maintenance and lack of flexibility, using the simulation assessment of the actual application method, this paper designs the injection molding machine control systems based on PLC controller, the new control system is composed by PLC, inverter, sensors and other components, with the help of PID control, which according to the given screw barrel temperature deviation value and measured value, automatically adjust and stabilize of the entire control system. Simulation experimental results show this new control system can achieve better performance is effective, which will decrease energy consumption of the stabilization system; the research achievements have certain theoretical and practical value to the design of injection molding machine control system.
