| titleOfInvention | Manufacturing Process of Inorganic Vacuum Shell Mold for Foundry |
| abstract | The invention discloses a manufacturing process of an inorganic vacuum shell mold for casting. After using an inorganic binder and adding a pearl sand, adding a mixed sand of the pearl sand and sea sand, or pure sea sand, the special equipment of the inorganic vacuum shell mold is used to form, Heating and curing, vacuumizing, drying, spraying paint, and assembling the shell mold after it is out of the mold to obtain an inorganic vacuum shell mold for casting. The process modeling and casting of the present invention has the following advantages over traditional lost wax modeling and casting. : There is no smoke and poisonous gas emission during the molding and casting process. The gas volume of the shell mold is about 1.5 ml/g, which greatly reduces the pores in the product and improves the quality of the shell mold. There is no need to bake the shell mold at high temperature before casting, and it can be directly cast. , The sand mold after casting is easy to collapse, which is convenient for sand cleaning. After the collapse, the sand mold can be recycled, and it can be cast on the same day of modeling, which greatly shortens the modeling and casting time. |
