What should you pay attention to when cooling castings in gravity casting machines?

     Gravity Casting Machine is a kind of casting equipment for casting products, which can be used to produce products in many industries, such as medical equipment, tableware, auto parts, electrical accessories, etc. The main structural components of the gravity Casting Machine support the production work of the gravity casting machine and also determine the good application effect in actual use. The main structural components supporting the production of the gravity casting machine include the main lifting cylinder, three-dimensional electrical box, flipping cylinder, flipping module, lower lifting and discharging module and mold clamping module. The gravity casting machine relies on the flip module to flip from 0 to 90 degrees. The invention has high guiding precision, strong balance and high mold closing precision, which is beneficial to processing and production and improves the quality and output of castings.

　　We know that gravity casting machines can produce products in many industries. Although different castings have different properties according to the needs of the manufacturers, and their processing techniques will also be different, they all have one thing in common, which is the cooling process of the castings. Casting cooling is an indispensable process anyway. Let the editor tell you what you should pay attention to when casting is cooling.

 

　　Before cooling the casting in the gravity casting machine, pay attention to whether the temperature of each part of the casting is the same. If the temperatures are the same, the cooling operation can proceed normally. If the temperature difference between different parts of the casting is large, the thick-walled part will undergo a phase change during the continuous cooling process and the volume will become larger. The thin-walled part will be elastically stretched by the inner layer to form tensile stress, while the thick-walled part will be elastically contracted by the outer layer. Create compressive stress.

 

　　This cooling process of the casting can lead to uneven wall thickness, deformation of the casting, and even problems with the overall quality of the casting. Therefore, the editor reminds everyone that before cooling the gravity casting machine, you should pay attention to whether the temperature of each part of the casting is consistent and whether there is a large temperature difference to avoid the cooling process affecting the quality of the casting.
