Mold temperature machines play a crucial role in industrial production, especially in processes such as injection molding. The following is a detailed explanation of the function and working principle of the mold temperature machine: I. The function of the mold temperature machine
1. Adjusting mold temperature: The main function of the mold temperature machine is to heat or cool the mold, keeping its temperature within the set range. This is crucial for the quality and production efficiency of injection molded parts.
2. Ensuring the quality of injection molded parts: By precisely controlling the mold temperature, the mold temperature machine can ensure that the injection molded parts have stable quality and consistent dimensions. Constant mold temperature helps reduce deformation, shrinkage, and cracking of injection molded parts.
3. Optimize processing time: The mold temperature machine can quickly heat the mold to the required working temperature and maintain this temperature stability, thereby shortening the injection molding cycle and improving production efficiency.
4. Energy saving and consumption reducing: Automatic mold temperature machine can effectively shorten the start-up time and save energy costs, thereby reducing production costs.
5. Reduce manual intervention: The fully automated control function of the mold temperature machine reduces the frequency of manual intervention, reducing the pressure and intensity of operational work. 2、 Working principle of mold temperature machine
The working principle of the mold temperature machine is mainly based on the principle of cyclic heat transfer, which achieves precise control of the mold temperature through heating, cooling, and cyclic processes. The specific steps are as follows:
1. Heating process: The mold temperature machine heats the medium (usually thermal oil or water) to the set temperature through heating elements (such as electric heating tubes). The heated medium becomes a hot fluid with high thermal conductivity.
2. Cycle process: The pump in the power transmission system transports hot fluid from the water tank equipped with heaters and coolers to the mold. The hot fluid releases heat in the mold, heating it to the desired temperature. The heated hot fluid returns from the mold to the water tank, completing one cycle.
3. Cooling process: When the mold needs to be cooled, the cooling system in the mold temperature machine starts working. The refrigerant in the cooling system cools the medium and forms a cold fluid. The cold fluid is transported into the mold, absorbs heat from the mold, and then returns to the water tank.
4. Temperature control: The temperature sensor is responsible for monitoring the actual temperature of the mold and transmitting the data to the controller. The controller calculates the required heating or cooling amount based on the difference between the set temperature and the actual temperature. The controller sends instructions to the actuator, which controls the operation of the heating element or cooling system to adjust the temperature of the mold.
5. Safety protection: Mold temperature machines are usually equipped with various safety protection functions, such as overheating protection, overload protection, and leakage protection, to ensure their safety and stability during operation.
The mold temperature machine ensures the quality and production efficiency of injection molded parts by precisely controlling the mold temperature. Its working principle is based on the principle of cyclic heat transfer, achieving precise control of mold temperature through heating, cooling, and cyclic processes. At the same time, the mold temperature machine is also equipped with various safety protection functions, ensuring its safety and stability during operation.
