Analysis of the working principle of the mold temperature machine


The mold temperature control machine is used to control the temperature of the injection molding machine mold, heat oil or water to the optimal temperature required for product molding, and send it into the mold loop to quickly increase the mold temperature to improve the molding efficiency and shorten the mold temperature. Machine principle time. The Guansheng mold temperature machine manufactured by our company uses the principle of heat exchange. The internal mold temperature heater and cooler of the machine can precisely adjust the temperature of water or heat medium oil, and quickly circulate through the mold to maintain stability during the molding time. Temperature to improve product quality and efficiency.
The main purpose of the mold temperature machine:
1. Plastic has the physical properties of thermal expansion and contraction. During the molding process, products often see some shrinkage, distortion, bubbles, silver streaks, deformation, cracks, poor transparency of plastic mold thermostats, poor smoothness, defects and other undesirable phenomena. The main reason for this bad phenomenon is that the mold temperature of the product is not stable before the molding and the mold temperature cannot reach the product molding temperature during the molding process. Engineering plastics such as PC, PA, PBT, etc. have relatively high temperature requirements. The heat of the injection molding machine itself cannot meet the optimal temperature required in the molding process, and the mold temperature control machine can quickly increase the temperature of the mold and can be based on the requirements of different raw materials. The temperature can be adjusted freely and the temperature stability of the mold is guaranteed. The Kawamoto mold temperature machine can reduce the defective rate of the product.
2. In the die-casting work, the mold temperature is kept in the optimal range, the mold will not overheat and reduce the sticking mold, and the production can be performed at a constant temperature.
3. Matching rubber machine and extruder temperature control Guansheng mold temperature machine to survive by quality, service and development.
PID system control, using imported temperature controller, temperature difference is ± 1 ℃.
Imported high temperature resistant pump, high pressure, large flow, to achieve the best exchange efficiency.
The electric heating tube made in Taiwan is selected for long life.
The main control electronics and operating elements inside the machine are imported brand-name.
Prepare to replace the media valve, easy to use.
Excellent sturdy frame, extremely easy to maintain.

Purpose of mold temperature machine
A. Improve molding efficiency:
1. Before molding, CBE automatically controls the mold temperature, quickly reaches the required temperature and always maintains constant temperature, reducing the man-hours required for mold preheating.
2. Continuous operation without worrying about too high mold temperature, and stop on the way without waiting for temperature rise due to lower mold temperature, which can improve production efficiency.
B. Improve product quality:
1. Plastic has the physical characteristics of thermal expansion and contraction, so if the mold temperature is unstable or improperly controlled, it will produce watermarks, shrinkage, distortion, deformation, and poor surface gloss, which can be solved by using TMC models. Such problems.
2. It can promote the mold to maintain an appropriate temperature, greatly reduce the number of molds and the defective rate of the molded product, and ensure product quality.
C. Structural characteristics:
1. You can choose water or medium oil as the heat transfer medium according to your needs.
2. Select the equipped PID intelligent automatic calculation temperature controller, which can accurately display and control the temperature difference of the mold within ± 1 ℃ of the required temperature.
3. The two-stage heating structure design can increase or decrease the power according to the required temperature, and cooperate with the special heating structure to save time and power.
4. A variety of thoughtful protection devices, such as: no fuse switch, water or oil shortage, temperature abnormality and automatic overload warning system, the circuit can be automatically cut off to ensure safety.
