| titleOfInvention | Water glass type copper mold casting process |
| abstract | The invention discloses a water glass type copper mold casting process which comprises the steps of wax mold production, shell surface course production, shell casting, shell finishing, and copper part casting and cleaning. Water glass is firstly casted, and a mold is produced by a vacuum heat treatment process, so that the mechanical property of castings is improved, the castings are easily cleaned, the surface roughness of the castings is low, the dimensional accuracy of the castings is high, the production period of the castings is short, the surface quality of copper castings cast by the castings is good, the phenomena of sand penetration, shakeout and pores are obviously reduced, the cracks and pores defects of the copper castings are greatly eliminated, the quality of steel castings is improved, and the cost is obviously reduced. |
