The injection molding machine controller is an important part of the injection molding machine. It is responsible for controlling various parameters during the injection molding process to ensure product quality and production stability. The control system of a modern injection molding machine usually includes a temperature control system, a motion control system, etc., to achieve precise control and adjustment of parameters such as time, position, pressure, and speed during the injection molding process of the injection molding machine.
Injection molding machine controller type
There are three main types of injection molding machine controllers: traditional relay type, programmable controller type and microcomputer control type.
Programmable computer controller (PCC) combines the characteristics of PLC and industrial control computers, can provide more powerful data calculation and processing capabilities, and has been widely used in injection molding machine control systems.
Basic usage methods and precautions for injection molding machine controller:
Emergency mold opening function:
In an emergency, you can press the emergency mold opening button to immediately stop the mold closing process and open the mold instead.
Safety electric eye:
Injection molding machine controllers are usually equipped with safety electric eyes to ensure that if there is an object blocking the mold during the closing process, the controller will stop the mold closing process.
Display and setting of working parameters:
There will be an LED digital tube display on the controller panel to display segment timing, full time, output and other information. The displayed content can be selected through the "Timing/Counting" key. In addition, working parameters such as pressure, temperature and time can also be set through the controller.
Operation panel:
The indicator lights on the operation panel are used to indicate the corresponding time and pressure items. When an indicator light is on, the corresponding digital tube will display the corresponding time or pressure value.
Manual key area:
The bottom of the operation panel is the manual key area. Each key has a corresponding indicator light. When the light is on, it means that the corresponding action has output.
PLC control: PLC (programmable logic controller) control of injection molding machines is the mainstream method of modern injection molding machine control, which can provide higher control accuracy and convenience.
Operating procedures:
When using the injection molding machine controller, correct operating procedures should be followed, including startup operations, shutdown operations and precautions.
System analysis and maintenance:
Regularly analyze and maintain the injection molding machine control system to ensure its stable and reliable operation.
Intelligent control:
Modern injection molding machine controllers may include intelligent features, such as the CC300 control system, which provides modern operating logic, at-a-glance navigation and personalized configuration options.
Training and Support:
Before using an injection molding machine controller, operators should receive appropriate training to ensure they understand all functions and operating requirements of the controller.
Development of injection molding machine controllers
Injection molding machine controllers are constantly developing towards higher precision and higher efficiency. For example, some advanced injection molding machine controllers have 5 to 10 levels of injection speed, multi-stage pressure holding and sol back pressure control. Through the combined use of displacement/speed sensors, pressure sensors, closed-loop injection controllers and high-response servo valves, Achieve precise control of sol back pressure, injection speed and pressure holding conditions during the injection molding process.
Injection molding machine controllers are a key factor in ensuring the efficient operation of injection molding machines. With the continuous advancement of technology, controllers are becoming more intelligent and automated to improve production efficiency and product quality.
