By precisely controlling the mold temperature, it ensures that the plastic material reaches the best state during the molding process. This device integrates the functions of the mold temperature controller and the feeder. The mold temperature controller is responsible for heating or cooling the mold to maintain the mold within an appropriate working temperature range, while the feeder is responsible for accurately and stably conveying the plastic raw material into the mold. The two work together, improving the efficiency and product quality of plastic molding, and also helping to reduce energy consumption and production costs. The feeding device of the mold temperature controller is widely used in plastic molding processes such as injection molding, extrusion, and blow molding.

[0026] When working, first, fuel is transported from the first bin 17 to the second bin 15 through the first feeder 16. When the fuel in the second bin 15 reaches the set position, the limiter transmits a signal to the feeder motor 18 at the outer end of the first feeder 16 to stop running.

The auxiliary motor 11 of the second feeder 10 determines the amount of fuel entering the mold temperature controller 13 according to the temperature difference of the set temperature. If a sudden power failure occurs, the liquid outlet solenoid valve 9 of the liquid outlet pipe 7 is activated, and the water tower 1 is connected to the liquid outlet pipe 7 to transmit water flow to the feeder and flow into the mold temperature controller 13 for cooling and extinguishing the fire, quickly reducing the temperature. Moreover, the water tower 1 has a large water storage capacity to ensure sufficient fire extinguishing water source and automatically complete the water injection and fire extinguishing process. Secondly, the cylinder 25 is used to drive the liquid outlet pipe 7 to inject water flow into the second bin 15, effectively wetting the raw materials at the bottom of the bin, ensuring that the internal raw materials reach a non-combustible level, quickly reducing the temperature of the raw materials, and avoiding spontaneous combustion inside the second bin 15. The motor speeds of the two groups of feeders are controlled by the temperature value of the temperature sensor 24. According to the feedback of the temperature sensor 24, the motor speeds are accurately adjusted to ensure the temperature stability inside the mold temperature controller 13, avoid temperature fluctuations, and prevent fuel spontaneous combustion caused by too high temperature. After a power failure, the main electric cabinet 8 can control the alarm 23 to monitor and alarm in real time. When a fire or potential fire risk is detected, an alarm is immediately issued to ensure that the staff can take countermeasures in the first time, reducing the risk of equipment damage and production interruption, reasonably allocating and adjusting the operation parameters of each device, realizing the optimal allocation of resources, and ensuring the safety of the equipment.

Moreover, the water storage capacity of the water tower 1 is large, ensuring sufficient fire extinguishing water source. The water injection and fire extinguishing process is automatically completed without manual intervention, improving the fire extinguishing efficiency and safety. Secondly, the liquid outlet pipe 7 can inject the water flow into the second bunker 15, effectively wetting the raw materials at the bottom of the bunker, ensuring that the internal raw materials reach the non-combustible level, rapidly reducing the temperature of the raw materials, and avoiding spontaneous combustion inside the second bunker 15. The motor speeds of the two groups of conveyors are controlled by the temperature value of the temperature sensor 24.
