The mold temperature machine of the plastic thermoforming machine is also called the mold temperature control machine, which was originally used in the temperature control industry of the injection mold. Later, with the development of the machinery industry, the application became more and more extensive. Now the mold temperature machine is generally divided into a water temperature machine and an oil temperature machine, and the temperature control accuracy can reach ±0.1 °C. Mold temperature machines are widely used in plastic molding, die casting, rubber tires, rollers, chemical reactors, bonding, banburying and other industries.
In a broad sense, it is called temperature control equipment, which includes temperature control in both heating and freezing. There is also a lot of room for the application of mold temperature machines in the die casting industry, especially in the manufacture of magnesium alloys and aluminum alloys. Uneven or inappropriate mold temperature will lead to unstable dimensions of the castings, and the deformation of the castings during the production process. Defects such as thermal pressure, mold sticking, surface depression, internal shrinkage cavities and thermal bubbles are generated. It also affects the production cycle, such as filling time, cooling time and spraying time all produce unstable variables. The life of the mold will also cause hot cracks in the expensive steel due to the impact of supercooling and superheating, accelerating its aging.
The use of mold temperature machine in the plastics industry is relatively common, the main functions are:
1. Speed up production progress, reduce energy consumption and save energy.
2. Reduce the production of defective products.
3. Improve the molding efficiency of the product.
4. Improve the appearance of the product and suppress the defects of the product.
