The principle and function of special mold temperature machine for injection molding

The special mold temperature machine for injection molding is widely used in the plastic industry. Its main function is to heat the mold and maintain its working temperature, to ensure the quality of the injection molded parts and optimize the processing time. To ensure the quality of the injection molded parts and optimize the processing time. Injection molding special mold temperature machine, injection temperature control machine, injection water temperature machine, injection oil temperature machine, etc.

In the injection molding industry, the temperature of the mold has a decisive effect on the quality of the injection molded part and the injection time. Uneven or inappropriate mold temperature will lead to unstable casting size, and the casting will be deformed during the production process. Produces defects such as heat pressure, adhesive mold, surface depression, shrinkage cavity and thermal bubble. It also affects the production cycle, such as filling time, cooling time and spraying time. It also produces unstable variables. In addition, the life of the mold will also Due to the impact of overheating and overheating, the expensive steel material is thermally cracked and accelerates its aging. The injection mold temperature machine is used to adjust the equilibrium modulus of the mold temperature, and can be heated or cooled. The heat transfer medium with high heat transfer is used to In a short period of time, the excess heat in the mold is sent away. After setting the heat balance temperature, the temperature can be automatically controlled within a very small error, and the fixed value can be maintained. After setting the heat balance temperature, it can automatically Control its temperature within a very small error, and can maintain a fixed value.

Pre-conditions for the effective control of mold temperature by injection molding temperature control system The temperature control system is formed by three parts: mold, mold temperature machine and heat transfer fluid. In order to ensure that heat can be added to the mold or removed, the requirements of each part of the system must be: first Inside the mold, the surface area of the cooling passage must be large enough, the curved path of the flow path should match the power of the pump (the pressure of the pump), and the temperature distribution outside the cavity has no significant influence on the deformation of the whole machine and the pressure inside the machine. The cooling channel can reduce the pressure inside, thus improving the quality of the injection molded parts.

The special mold temperature machine for injection molding makes the mold temperature reach the suitable temperature required by the molding process, so that the temperature of each part in the cavity is basically the same, that is, the mold temperature is balanced in the production process. The temperature can be adjusted according to the required temperature of the product. The temperature control range of the special mold temperature machine for injection molding; the heat transfer medium is water, the highest use is 180 degrees, the heat transfer medium is heat transfer oil, and the maximum use temperature is 350 degrees. Temperature control accuracy; within ±1 °C. Various special models can be developed according to the customer's production process. The article was edited by Bo Sheng.
