Abstract
PURPOSE: To obtain the sand for the mold of high strength at the casting and superior collapsing property after molding by substituting part of the molding sand of the portion not in direct contact with molten metal with the specific bagged sand.
CONSTITUTION: Ordinary binder-containing sand 4 is packed around the portions in direct contact with molten metal, such as the cavity 2 and cross gate 3 formed by patterns in flasks 1 and the sand 4' which is sealed in the bag composed of material readily breakable by heat or artificially and which does not contain any binder is packed in the other portions. Even when a core 5 is required, the bagged sand 4' is used for its central part. The packing pressure in the bag is regulated to positive or negative pressure depending upon the object. This method enables the mold of the sufficient strength at the casting to be formed and makes the taking out of the casting easy because the bags break after the molding.
