Technical Field
[0001] The invention relates to the technical field of casting, and in particular to a high-efficiency demoulding device for castings. Background Art
[0002] Metal castings have a profound impact on industrial development. As one of the basic processes in the manufacturing industry, casting technology can produce parts with complex shapes and precise dimensions, and is widely used in the fields of automobiles, aerospace, machinery manufacturing, energy, etc. It not only improves production efficiency and reduces costs, but also promotes the progress of materials science and process technology. Through casting, metal materials can be used efficiently, which promotes the diversification and performance improvement of industrial products, provides important support for the scale, automation and precision of modern industry, and becomes a key driving force for the industrial revolution and the development of the modern industrial system.
[0003] The demoulding process after casting is crucial in the casting process and directly affects the quality, production efficiency and cost of the casting. Demolding refers to the process of removing the solidified casting from the mold. Improper demoulding operation may cause surface damage, cracks or deformation of the casting, affect its dimensional accuracy and appearance quality, and even cause waste. Reasonable demoulding methods can reduce wear and damage to the mold, extend the service life of the mold, and reduce production costs. The demoulding process is closely related to mold design, cooling system, lubricant use, etc. Optimizing the demoulding process helps to improve the overall level of the casting process.
[0004] A Chinese invention patent with announcement number CN110918949B discloses a demoulding device for sand mold casting. The device generates vibrations between the sand box, the molding sand and the casting, causing the molding sand and the casting in the sand box to fall off, and controls the demoulding direction at the same time to avoid damage to the casting due to excessive force during demoulding. However, the device cannot remove the casting from a large amount of molding sand. When processing multiple castings, it is easy to cause collisions between the castings, reducing the accuracy and yield of the castings. At the same time, the molding sand cannot be effectively recovered, reducing the demoulding efficiency of the casting. In addition, the cleaning of the sand box by this device is not thorough enough, and a large amount of molding sand is likely to remain on the sand box, reducing the demoulding efficiency.
