Timing-controlled hot runner system
The timing-controlled hot runner system is a hot runner system that uses a time controller to control the movements of the various components in the hot runner system to achieve the desired molding effect. The time controller typically consists of a microprocessor, sensors, actuators, and control software.
Main components of a timing-controlled hot runner system:
1. Timing controller: the timing controller is the core of the timing-controlled hot runner system, responsible for controlling the movements of the components in the hot runner system.
2. Sensors: sensors are used to detect the status of the hot runner system, such as temperature, pressure, and position.
3. Actuators: actuators are used to execute the control instructions of the timing controller, such as opening and closing valves, changing temperature or pressure, etc.
4. Control software: control software is used to compile the control program of the timing controller.
Working principle of the timing-controlled hot runner system:
1. After the injection molding machine is locked, the timing controller detects the locking signal, and then controls the hot runner to open according to the preset program, and the molten plastic begins to flow into the cavity.
2. After the molten plastic fills the mold cavity, the timing controller controls the hot runner to close and controls the temperature and pressure of the hot runner to meet the molding requirements.
3. After the injection molding is finished, the timing controller controls the hot runner to cool down to ensure the molding quality of the product.
Advantages of the timing-controlled hot runner system.
1. can improve injection molding efficiency and quality.
2. can reduce waste.
3. can extend the service life of the mold.
4. can meet the processing needs of complex molded products.
