摘要： An apparatus and method for making cores from green sand continuously and automatically. The method comprises blowing the green sand together with compressed air into a die cavity formed by a pair of dies, stabbing the green sand filled in the die cavity by stabbing rods to compact the green sand thereby to form a core, and applying a surface stabilizing agent to the surface of the core taken out from the dies, followed by drying of the core. Disclosed also is an apparatus suitable for carrying out this method.

摘要： Molding sand (5) is fed into a space defined by a pattern plate (2) and a flask (3) mounted on the pattern plate (2), and the space is enclosed at the upper part of the flask (3) by a cover (6). The air in the enclosed space is evacuated to reduce the air pressure between the grains of the molding sand in the enclosed space to 1 Torr to 150 Torr, and then air is introduced into the enclosed space from the upper part of the space so that the pressure in the space can increase at the rate of 15 atm/s to compress the molding sand (5). The method eliminates the need for vent holes and enables the mold to be crack-free since the air flow is not reflected.

摘要： A method and apparatus are provided to process collected sand. This method and apparatus allow the moisture content to be adjusted and the addition of a binder to be facilitated to renew the collected sand as casting sand for future use. Also, defective castings are prevented when they are made by a main mold using the renewed casting sand. The sand-collecting means can be compact. The method is performed and the apparatus is operated by separating a main mold of green sand, after casting is conducted, into parts unaffected and affected by the molten metal heat, adjusting the moisture content of the part unaffected by molten metal heat for use as facing sand in the next main mold making, and adding a binder and adjusting the moisture content of the part affected by the molten metal heat for use as back sand in making the next main mold.

摘要： Molding sand filled in a space defined by a pattern plate and a flask is pre-compacted before the molding sand is completely pressed. A pre-compacting member is inserted into the molding sand toward the pattern plate, and then is stopped based on a predetermined depth of the pre-compacting member in the molding sand or a predetermined pressure caused by the pre-compacting member in the molding sand.

摘要： Given green sand is obtained by a mixing operation that is carried out for a short period of time. Discarded sand is supplied as supplementary sand to a sand processing line, so that molding sand can be recycled. Green sand for a molding is used for facing sand or the pocket sand. Bentonite-covered sand is made by mixing reproduced sand, new sand, and discarded sand or any or all of them. The bentonite-covered sand is added to collected sand to supplement it. Also, the bentonite-covered sand is mixed with water, and used for facing sand or the pocket sand.
