Thermal system design
1. Flame heating. The flame heating is mainly controlled by the enterprise gas, and is heated by natural gas burner technology or blowtorch.
2. Heating device is used for heating, and resistance heater is commonly used.
3. Mold temperature controller heating, mold preheating range: zinc alloy (150-200 °), aluminum alloy (180-300 °).
4. Device design of electric heating system: mainly through the type and number of electric heating rods to select and install the position of holes and temperature measurement holes.
Cooling system design
1. Mold cooling method
Water cooling, air cooling, cooling with high heat transfer coefficient alloy, heat pipe cooling and mold temperature control device.
2. Arrangement of cooling channel: the diameter of cooling channel is generally 6-16mm, and the clearance distance is>15mm.
3. Design and calculation of cooling channel
(1) The heat flux of liquid metal entering the die casting process is calculated.
(2) Calculate the length of the cooling channel.
The above is the introduction of die casting mold factory on how to design the mold heating and cooling system. I hope I can help you.
(2) Metallographic examination: check the shrinkage, distribution, grain size and intergranular impurities of cementite on the dislocation of the main material.
(3) Ultrasonic flaw detection is mainly used to check the internal defects and dimensions of materials.
