For all die casting mold factories, die casting mold design and manufacturing technology is an important factor of core technology and key technology, but also the strength of die casting mold factories. Today, we will discuss and learn about the design technology of die casting mold heating and cooling system.
For all die casting die manufacturers, die casting die design and manufacturing technology is an important factor of core technology and key technology, as well as the strength of die casting die manufacturers. Today, we will discuss and learn about the design technology of heating and cooling systems for die casting dies
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 products produced by the die casting mold 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
1、 Thermal system design
1. Flame heating, which is mainly controlled by enterprise gas and natural gas burner technology or using blowtorch
2. The heating device is commonly used for heating
3. Mold temperature controller heating, mold preheating range: zinc alloy (150-200°) Aluminum alloy (180-300°)
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
2、 Cooling system design
1. Mold cooling method
Water cooling, air cooling, alloy cooling with high heat transfer coefficient, heat pipe cooling and mold temperature control device for cooling
2. Layout form of cooling water channel: the diameter of cooling water channel is generally 6-16mm, and the clearance distance is> 15mm。
3. Design calculation of cooling water channel
(1) Calculate the heat flow of molten metal into the mold during die casting
(2) Calculate the length of cooling water channel
The above is how the die casting mold factory introduces the mold heating and cooling system design. I hope it can help you
