In the process of blow molding, the hollow blow molding machine can bring high operating efficiency for users, so as to have relatively high economic benefits. If the hollow blow molding machine is used for a long time, the current temperature of the blow molding machine will be relatively high. Many users will ask whether it is necessary to take the active cooling after using the hollow blow molding machine for a long time.
HUAN machinery to tell you that in the process of blow molding, hollow blow molding machine in the process of work needs to be prepared raw materials on the feeder by feeder to the cylinder, the raw material again by cylinder preheating and heat, the temperature of the hollow blow molding machine will be relatively high, only after the thermoplastics melt completely can continue to use, Although blowing machine equipment for a long time without active cooling, so blowing machine heat by what divergence? That's right. The blow molding machine has its own cooling system.
First, what is the effect of the cooling water used in the cooling system of the hollow blow molding machine on the products
Accelerate cavity cooling
Cooling water accelerates the cooling of the mold cavity. After the product is finished forming, the cooling water enters the mold cavity in order to make the product better separated from the mold cavity and complete the demold after forming.
After entering the mold interior and forming preliminally, cooling water is needed to cool the mold. Cooling water can accelerate forming. In addition to accelerating forming, the cooling water of the hollow blow molding machine also ensures the geometric shape and internal structure of the product. Of course, not all products can be cooled with the same cooling water. We also need to consider the material of the products. If the products are made of non-crystalline materials, cooling water can be used to cool them directly. If the products are made of crystalline materials, cooling water can be used to cool them directly, which will not only ensure the quality of the products, but also cause quality problems. Next, it is time to say what effect does the cooling water of the hollow blow molding machine have on the equipment itself
Reduce the temperature of device components
In the production process of hollow blow molding machine, the operation and production needs of blow molding equipment will make the temperature of some parts too high. The role of cooling water in this case is to reduce the temperature of these parts, so as to avoid overheating and failure of the equipment;
When the screw is working, it will produce a lot of heat because of high-speed rotating stirring. The role of cooling water here is to eliminate the phenomenon of friction overheating of the screw, so as to stabilize the plasticizing ability of the screw. But the cooling process of the screw needs to be gradual. Long-term use of hollow blow molding machine, in order to ensure the operational efficiency, prolong the service life of hollow blow molding machine, even with the corresponding response, but before operation or the need for the corresponding inspection, used for maintenance after completion of work, should also be hollow blow molding machine, such as the temperature of the cooling after maintenance and maintenance, to avoid dangerous accidents.
