How do die casting plants design the heating and cooling of molds?
We must know the heating and cooling system of the compression mold, mold temperature is an important factor affecting the quality of the products produced by the die casting plant, so we must strictly control the mold temperature, and the temperature of the casting mold is determined by the control and regulation of its heating and cooling system.
For alldie casting plants, the design and manufacturing technology of die casting die is an important factor in the core technology and key technology, as well as the strength of the die casting plant. Today, I will discuss and learn about the design technology of the heating and cooling system of die casting die< br>
First of all, we must know the heating and cooling system for compressing the mold. The mold temperature is an important factor affecting the quality of the products produced by the die casting factory. Therefore, we must strictly control the mold temperature, and the temperature of the casting mold is determined by the control and adjustment of its heating and cooling system. Its main function is to achieve better heat balance and improve the solidification conditions of die castings. Die castings with improved internal and surface quality. Stabilize dimensional accuracy of die castings. Improve the productivity of die castings. Reduce the thermal alternating stress of the die. To improve the life of die casting die< br>
1、 Thermal system design
1. Flame heating, which is mainly controlled by enterprise gas and natural gas burner technology or using blowtorch< br> 2. The heating device is commonly used for heating< br> 3. The mold temperature controller heats the mold. The preheating range of the mold is zinc alloy (150-200 °) and aluminum alloy (180-300 °)< br> 4. The electric heating system device is designed mainly through the model and quantity of the electric heating rod and the position of the installation hole and temperature measurement hole< br> 2、 Cooling system design
1. Mold cooling method (1) Water cooling (2) air cooling (3) alloy cooling with high heat transfer coefficient (4) heat pipe cooling (5) mold temperature control device for cooling< br> 2. Layout form of cooling water channel: the diameter of cooling water channel is generally 6-16mm, and the gap distance is ＞ 15mm< br> 3. Design calculation of cooling channel (1) The heat flux of molten metal into the die casting process is calculated< br> (2) Calculate the length of the cooling channel< br> The above isThe die-casting factoryintroduced how to design the mold heating and cooling system.
