Description

TECHNICAL FIELD

[0001] The utility model relates to foundry processing equipment field especially relates to a quick cooling air cooling box. BACKGROUND

[0002] In the production of small batch experimental castings, cooling by appropriate speed air cooling not only improves the cooling efficiency, but also has a crucial impact on the microstructure and performance of the castings. Proper air cooling can ensure the formation of fine microstructure during the cooling process of the castings, such as in aluminum alloy castings, high cooling rate can reduce the secondary dendrite arm spacing (SDAS) and refine the eutectic particles, thereby improving the ductility and tensile properties of the castings. In addition, appropriate cooling speed can effectively control the thermal gradient inside the casting and reduce the risk of deformation or cracking caused by uneven cooling. Uniformly reheating the castings and wrapping them with materials that help retain heat, allowing the parts to cool as slowly as possible, can avoid the problem of increased thermal gradient caused by rapid cooling. Therefore, the use of appropriate speed air cooling technology in small batch experimental castings can not only improve production efficiency, but also maintain the quality and performance of the castings, while preventing deformation caused by improper thermal gradient control.

[0003] At present, fans are generally used to cool the castings directly, but the air flow distribution of fan cooling is uneven, resulting in inconsistent cooling speed of the castings, which can cause uneven thermal gradient inside the castings and increase the risk of deformation and cracking of the castings. Secondly, the efficiency of fan cooling is relatively low, because the wind speed and temperature control produced by the fan is not accurate, which can cause the cooling speed to be too fast or too slow, affecting the microstructure and final performance of the castings. Therefore, a cooling device with sufficient cooling capacity is needed to meet the needs of certain experimental high-performance castings, especially in applications that require rapid cooling to obtain specific microstructure.
