In the invention, the temperature rise accelerates the oxidation reaction rate between water and oxygen, and according to the chemical kinetics theory, as the average kinetic energy of molecules increases with the temperature rise, the collision frequency and energy between molecules also increase, thereby promoting the reaction, so that the temperature rise can increase the reaction rate; for the oxidation reaction between water and oxygen, the temperature rise can increase the conversion rate of the dissolved oxygen in the water to the oxygen, which means that the dissolved oxygen in the water is more easily oxidized at high temperature, so that the possibility of raising the PH value of the water is increased, the temperature of the mold is high, when the circulating water cools the mold, the circulating water in the waterway of the mold is rapidly raised, and the PH value of the circulating water is raised;
high PH water may cause corrosion of the metal on the mold surface, resulting in mold damage or failure; dissolved substances in water are easier to separate out and form sediment at a high pH value, and problems such as pipeline blockage, filter blockage and the like can be caused in a cooling system; high PH water may provide a suitable environment for bacterial growth, which may lead to bacterial contamination and bio-corrosion problems in the cooling system;
the water inlet pipe 13 is communicated with the water channel of the die, when the circulating water in the water channel of the die enters the water inlet pipe 13, the electronic PH meter 15 firstly measures the PH value of the water, if the PH value is increased, an acid solution (such as citric acid, acetic acid and the like) is added into the water inlet pipe 13 through the feeding pipe 14 to reduce the PH value of the water, and the diameter and the water flow speed of the water inlet pipe 13 are known, and an appropriate acid solution can be accurately added through calculation, so that the PH value of the circulating water is prevented from being increased, the shunt pipe 23 and the water channel of the die are blocked and scaled, and the cooling efficiency is reduced.
