Description

Technical Field

[0001] This utility model relates to the technical field of cooling equipment for die castings, specifically an air-cooling device for rapid cooling of products after die casting. Background Technology

[0002] In modern industrial production, die casting technology is widely used in many fields such as automobiles, electronics, and aerospace due to its advantages of high efficiency and high precision. With the continuous growth in demand for die-cast parts, how to cool die-cast parts quickly and efficiently has become a key link in improving production efficiency and product quality. Traditional natural cooling, while simple to operate, results in extremely low production efficiency due to its lengthy cooling time. Furthermore, variations in storage conditions and environmental factors lead to inconsistent cooling rates in die-cast parts, causing unstable mechanical properties and even localized cracks, severely impacting product quality. While water cooling can accelerate cooling to some extent, the excessive temperature difference can easily generate strong internal stresses within the die-cast parts, leading to cracking and failing to meet the demands of high-quality production. Existing air-cooling systems also have many drawbacks. For example, some systems use methods such as stacking die-cast parts for air cooling or simply setting up air-cooling devices on both sides of the production line, resulting in severe uneven cooling, difficulty in accurately controlling the cooling time of the workpieces, and unsatisfactory cooling effect on the internal die-cast parts. Some air-cooling systems rely on axial flow fans, which have insufficient air volume and pressure, resulting in low cooling efficiency and difficulty in cooling the die-cast parts to the appropriate temperature in a short time. At the same time, some air-cooling systems lack or fail to implement adequate safety protection measures, posing a potential threat to operators during production. Furthermore, some air-cooling systems have unreasonable feeding rhythm and cycle settings, resulting in significant energy waste and a substantial increase in production costs. Therefore, there is an urgent need to improve the air-cooling equipment for rapid cooling of die-cast products to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This air-cooling equipment for rapid cooling of die-cast products, through the design of its cooling mechanism, first performs air cooling, which can initially and quickly remove a large amount of heat from the die-cast parts, reducing their temperature peak and avoiding sudden cooling. Then, water cooling can further reduce the temperature efficiently. The combination of the two significantly shortens the cooling time and increases the cooling rate. At the same time, cooling gas is injected into the hollow conveyor rollers, which can cool the die-cast parts from the bottom, achieving all-round cooling, making the cooling more uniform, effectively reducing internal stress and deformation caused by uneven cooling, improving the quality of die-cast parts, and optimizing the overall cooling effect.

[0012] 2. This air-cooled equipment for rapid cooling of die-cast products, through its drying mechanism design, can quickly remove residual moisture from the surface of die-cast parts, significantly shortening drying time, improving production efficiency, and avoiding process delays caused by waiting for natural drying. Furthermore, the strong airflow ensures uniform and rapid moisture removal, preventing localized water accumulation and effectively reducing defects such as water stains and rust spots, thus improving the appearance quality of die-cast parts. Moreover, rapid drying reduces the risk of corrosion to the die-cast material caused by moisture, extending the service life of the die-cast parts. In addition, the efficient drying process can better integrate with subsequent processing steps, optimizing the overall production process and ensuring stable product quality.
