摘要

"METHOD AND APPARATUS TO SEPARATE PRODUCT IN THE GROSS STATUS OF FUSION OF THE GREEN SAND MOLD PROVIDED WITH THE MELTED METAL". This invention provides a method and apparatus for removing a raw melting product from a green sand mold that has been provided with the molten metal in such a way that the raw melting product is not damaged. The method of the invention is characterized by separating a product in the raw melting state from a green sand mold that has been provided with the molten metal, comprising the steps of transferring an upper component from the green sand molding box and a lower component from the box molding green sand that have been filled with molten metal in a casting line from the casting line to a predetermined location; hermetically encircle within a chamber at least one of the upper or lower components of the green sand and a product in the raw state of melting in at least one mold of green area, both of which are located in the predetermined location and evacuate the chamber to lower the point boiling moisture in the condensed layer by the moisture of at least one green sand mold, to boil the moisture in the moisture condensed layer to cause collapse in at least one green sand mold, thereby separating the product in the raw melting state of at least one green sand mold.
