Description

Technical Field

[0001] The utility model relates to the technical field of precision casting shell making, in particular to a surface coating device for precision casting shell making. Background Art

[0002] Precision casting shell making is a key step in the precision casting process. It involves injecting the molten metal solution into a pre-prepared shell mold to form a high-precision casting. The shell mold can be improved to have sufficient strength and air permeability to ensure that the metal solution can be smoothly filled and solidified. The shell mold surface also needs to be coated with one or more layers of special coatings to improve the quality and performance of the casting.

[0003] After the shell production of precision castings, surface coating is required. The coating can fill the gaps on the surface of the sand mold and sand core, forming an effective fire-resistant barrier to avoid problems such as mechanical sand adhesion, chemical sand adhesion and surface roughness of the casting. After using the coating, the surface roughness of the casting can be significantly reduced; the coating can reduce the burrs on the casting caused by surface cracking of the sand mold or sand core, and reduce the incidence of defects such as sand blasting, sand falling, and sand holes.

[0004] In the existing technology, the structure of the precision casting shell is relatively complex, which makes it inconvenient to apply paint to the internal surface layer. The precision casting shell needs to be clamped in the paint so that the paint is adsorbed on the surface of the precision casting shell. However, the application is not uniform and the paint easily stays inside the precision casting shell. Here we provide a surface coating device for precision casting shell. Utility Model Content
