Description

Technical Field

[0001] This utility model belongs to the field of casting mold spraying technology, specifically relating to an automatic casting mold spraying device. Background Technology

[0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. Because the molding materials used in sand casting are inexpensive and readily available, and the mold making is simple, it is suitable for single-piece production, batch production, and mass production of castings, and has long been a fundamental process in casting production. Sand casting molds generally include wooden molds and iron molds. Large castings generally use iron molds. The mold is filled with casting sand, and the surface of the casting sand is usually sprayed with a binder. To facilitate mold cleaning after casting, a release agent or other treatment liquid is sprayed onto the inner wall of the mold for easy demolding. In current processes, workers typically move the mold and use a handheld spray gun to spray the mold in a designated area. This method is not only inefficient and has low efficiency in using the treatment liquid, but it also easily leads to omissions or uneven spraying. Furthermore, for large iron molds, moving the mold is time-consuming and labor-intensive, and the process can easily cause secondary contamination inside the mold. Utility Model Content
