1. The heat balance of the injection mold controls the heat conduction of the injection molding machine and the mold is the key to producing injection molded parts.
2. Preliminary conditions for effective control of mold temperature The temperature control system consists of three parts: mold, mold temperature controller, and heat transfer fluid.
3. Working principle The mold temperature machine is composed of water tank, heating and cooling system, power transmission system, liquid level control system, temperature sensor, injection port and other components.
4. The types of mold temperature controllers are classified according to the heat transfer fluid (water or heat transfer oil) used.
5. Control the unevenness of the temperature in the mold, which is also related to the time point in the injection cycle. After injection, the temperature of the cavity rises to the highest, when the hot melt hits the cold wall of the cavity, the temperature drops to the lowest when the part is removed.
6. The configuration of the mold temperature machine and the configuration of the mold temperature machine used should be comprehensively judged according to the material to be processed, the weight of the mold, the required preheating time and the productivity kg/h.
