发明名称 Molding process and apparatus
摘要 A molding process and an apparatus wherein the molds produced in a molding machine are sent past a casting apparatus where casting takes place. Thereafter, the molds with the molding boxes surrounding them, pass through a primary cooling line, at the end of which molds and molding boxes are separated. The molding boxes are returned to the molding machine, while the sand molds with the castings pass through a secondary cooling zone for further cooling. The process allows for a substantially smaller number of molding boxes than previously known molding processes.
