Description
Technical Field
[0001] The utility model relates to the technical field of lost foam equipment, and more specifically to a high-efficiency and energy-saving lost foam equipment for hammer casting. Background Art
[0002] Lost foam casting, also known as full-mold casting or foam plastic mold casting, is an advanced casting process. It uses a foam plastic mold and is molded by dry sand without a binder and vacuum technology. Then, negative pressure pouring is performed to vaporize the model, and the liquid metal occupies the position of the model. After solidification and cooling, a casting is formed. Lost foam casting has many advantages, such as precise casting size and shape, high surface finish, improved casting tissue density and process yield, etc.
[0003] The existing lost foam equipment, whose mold is a foam plastic mold, is directly placed on the workbench. Since there is no fixing mechanism and the material is light, it is easily moved by the resistance wire during the cutting process and deviates, resulting in a certain gap between the cut shape and the original shape; and the existing lost foam equipment has different heights of the molds required in the working process, so the cutting head often needs to be extended during cutting. When the cutting head is extended, its original rigidity and stability may be affected, which may lead to a loss of precision during the cutting process. Utility Model Content
