Description

Technical Field

[0001] The utility model relates to the technical field of water purification for injection molding machines, in particular to a water purification system for an ice water machine for injection molding. Background Art

[0002] Injection molding machine is also called injection molding machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Because the injection molding machine needs to turn on the electric heat to heat each section of the barrel before production and processing, the injection molding machine has certain requirements for the working temperature.

[0003] However, if the temperature of the injection molding machine is too high, it will cause thermal deformation of the machine, reduce the viscosity of the oil, deform the rubber seals, and accelerate the oxidation and deterioration of the oil. In addition, the injection molding machine uses pressure oil, and the working temperature of the pressure oil cannot exceed the specified range. The ideal working temperature should be maintained between 45℃-50℃, and 35℃-60℃ is also more appropriate. Therefore, when the injection molding machine is working, it is necessary to use cooling water to cool it down.

[0004] However, the existing cooling water supply device, such as CN113199714A, provides a constant pressure water supply system for cooling injection molding machines. However, this device is mainly equipped with a water chiller for refrigeration, supplies cooling water of different temperatures, and sets a stable flow balance in the water supply pipe and the return pipe. The cooling water is often industrial water, which often contains too many impurities. The existing technology does not purify the water quality, resulting in blockage of the water chiller pipe. In the long run, the service life of the water chiller is greatly reduced.

[0005] Therefore, it is urgent to provide a water purification system for an injection molding ice water machine to solve the above technical problems. Utility Model Content
