Abstract (en)
[origin: EP1228826A1] This invention provides a method and an apparatus for taking out an as-cast product from a greensand mold that has been provided with molten metal such that the as-cast product is not damaged. The method of the invention is one that separates an as-cast product from a greensand mold that has been provided with molten metal, comprising the steps of transferring a greensand cope and a greensand drag that have been filled with molten metal at an casting line from the casting line to a predetermined place; surrounding airtightly within a chamber at least either one of the greensand cope and drag and an as-cast product in the at least one greensand mold, both of which are located at the predetermined place; and evacuating the chamber to lower the boiling point of the moisture in the moisture-condensed layer of the at least one greensand mold, to boil the moisture in the moisture-condensed layer to collapse the at least one greensand mold, thereby separating the as-cast product from the at least one greensand mold. <IMAGE>
