Good temperature function of injection molds can accelerate the crystallinity and uniform structure of formed products. Make the molding shrink sufficiently, and then reduce the shrinkage. That is to say, the product contracts in the later stages of production. Improve the strength and heat resistance of production products. Prevent product cracking and fragility. Reduce residual internal stress, molecular alignment, and deformation. Reduce common ripples or ripples in PP materials. Reduce the flow resistance during filling and reduce pressure loss. Make the appearance of formed products more shiny and better.
The purpose of injection mold warming machine:
1.During die casting work, the mold temperature should be maintained within a good range, and the mold should not overheat to reduce mold viscosity and produce sustainable temperature positioning. At the same time, it can improve the dimensional accuracy and surface finish of castings, prevent shrinkage and crack formation of castings, and better produce complex thin-walled castings.
2. Plastics have the physical properties of thermal expansion. During the molding process, products often exhibit some undesirable phenomena, such as shrinkage, distortion, bubbles, silver lines, deformation, poor transparency, unsmooth performance, defects, etc. The main reason for this undesirable phenomenon is the unstable temperature of the mold, which cannot reach the temperature required for product molding before molding.
3. The heat of the injection molding machine itself cannot meet the good temperature required during its molding process, and the mold temperature control function can quickly increase the mold temperature and freely adjust according to the temperature required for different raw materials, ensuring the temperature stability of the mold and reducing the defect rate of the product.
The mold temperature control machine is used to control the temperature of the injection molding machine mold, heating oil or water to the desired temperature for product molding, and sending it into the mold loop to quickly increase the mold temperature, improve molding efficiency, and shorten molding time. The mold temperature machine is the principle of controlling thermal exchange. The heaters and coolers in the machine can accurately adjust the temperature of water or heat medium oil, and quickly circulate during mold forming to maintain a stable temperature, thereby improving the quantity and efficiency of products.
The installation requirements for the injection mold temperature controller are as follows:
Before installing the injection mold heater, please choose a stable foundation, open and unobstructed surroundings, and avoid corrosion Pollution, exposure to sunlight, and rain, making it easy to install and maintain the site;
2. Select a matching cooling tower based on the cooling capacity of the injection mold temperature machine. Please install the piping for the injection mold temperature machine according to the size of the body. Do not reduce the size of the cooling water pipe, as it may cause high pressure overload, affect the cooling effect, and increase power consumption;
Please ensure that the air-cooled injection mold heater is installed at a distance of 1 away from the wall. The above spatial location is designed to avoid high voltage overload caused by poor heat dissipation, which can affect the cooling effect and increase power consumption.
