摘要： A first quantity of all the molding sand necessary to produce a mold is fed in the mold space, the first quantity being one of at least two parts divided from the total molding sand. The mold space is evacuated and then air is introduced into the mold space at the air-pressure rising rate of 30--to 500 kg/cm.sup.2 /sec. Another quantity of the molding sand is fed into the mold space, the mold space is evacuated and then air is introduced into the mold space at the air-pressure rising rate of 30--to 500 kg/cm.sup.2 /sec. The apparatus includes a sand passage through which each quantity of sand is fed into the mold space, and a gate for closing the sand passage thereby closing the mold space to allow the mold space to be evacuated and then subjected to a pressure increase.

摘要： A method of filling a core cavity, wherein the entire core cavity is uniformly filled with highly compacted sand for molding the core without the need of providing many ventholes. The method is characterized in that sand for molding the core is drawn into the core cavity through an inlet to preparatorily fill the cavity, and then the thus prepared sand is repeatedly and sequentially compacted by impulsively pressurizing the sand, starting with the sand farthest from the inlet and ending with the sand nearest to the inlet.

摘要： A method for connecting a plurality of cores in an assembly through adjacent surfaces of the adjacent cores is disclosed. This method includes the steps of: (a) forming a plurality of cavities between adjacent surfaces of two adjacent cores, the plurality of cavities being horizontally aligned and spaced apart along the adjacent surfaces; (b) arranging the plurality of cores in a row; (c) filling a hopper nozzle with a predetermined amount of connecting sand; (d) indexing the hopper nozzle above one of the cavities; (e) supplying compressed air into the hopper nozzle that contains the connecting sand, thereby projecting and charging the mass of the connecting sand from the hopper nozzle into the cavity; and (f) repeating steps (c), (d), and (e).

摘要： A method and apparatus is provided for increasing the packing density and strength of sand for gas-hardening casting molds. The method is characterized by the steps of filling spaces defined by a pattern plate 1 and a mold frame with gas-hardening casting sand 4, depressurizing a closed container 3 after the filled assembly has been conveyed thereinto, introducing air into the container 3, applying a pressure to the upper surface of the casting sand to increase its packing density, and hardening the casting sand by a hardening gas.

摘要： Cores have a plurality of cavities defined by adjacent vertical side surfaces of two adjacent cores. These cavities are arranged horizontally and spaced apart along the surfaces. Providing such a plurality of cavities in the surfaces produces an increased total surface area extending in the direction where the cores mate or separate.
