摘要： The casting process includes the steps of: preparing an upper mold assembly (20) by securing a core to an upper mold; pouring a necessary minimum amount of a molten metal for obtaining a casting in the hollow of the lower mold; moving downwardly the upper mold assembly at a predetermined first speed to a predetermined height level just before the upper mold assembly comes into contact with a surface of the molten metal in the hollow of the lower mold; further moving downwardly the upper mold assembly, from the predetermined height level, at a predetermined second speed by changing the descending speed of the upper mold assembly from the first speed to the second speed; detecting a status information of the upper mold assembly in a state when the upper mold assembly is superimposed on the lower mold, or arrived at the lower mold; and stopping the descending movement of the upper mold assembly after detecting that the status information comes at a predetermined state. The upper mold assembly is prepared by securing the core to the upper mold with a mechanical means, an adhesive, frictional engagement of a projection (24a,24b) with a recess (22a,22b) or engagement of a projection (24C) with stamped molding sand of the upper mold.

摘要： This invention provides a casting method for a casting of high quality and a press for casting such a casting by controlling the speed of the press that presses a mold in the pressing process, after a upper mold overlaps a lower mold.
The invention provides a casting method for a casting and the press for that casting method. They use the lower mold having a concave portion that has a shape of a casting, and the upper mold having a convex portion that has a shape of the casting, which convex portion forms a cavity to produce the casting by overlapping the lower mold.
A casting method to produce a casting and a press used for the casting method, using a mold which forms a cavity in a shape of a casting, so as to produce a casting by overlapping a lower mold with an upper mold, which molds are molded by a molding method, said casting method comprises steps of:
pouring into the lower mold a quantity of molten metal required to produce a casting;
lowering the upper mold at a predetermined first speed until the upper mold reaches a predetermined position just before the upper mold starts contacting a surface of the molten metal;
lowering the upper mold at a predetermined second speed after the upper mold is further lowered beyond the predetermined position ;
detecting and obtaining information on the status of the upper mold which overlaps the lower mold; and,
stopping the lowering of the upper mold when detecting the information on the status of the upper mold that shows that the predetermined conditions are met.
