摘要： A method of producing a mold core from green sand, wherein green sand is blown into a mold cavity which is sized to be greater than the size of the mold core to be obtained, so that a preformed mold body is prepared. The preformed mold body is then compacted by a compacting die having a cavity recess which is sized in conformity with the size of the mold core to be obtained, until the preformed mold body size is reduced to the final stage. In consequence, the green sand is compacted to develop uniform distributions of strength and hardness over the entire portion of the mold core as the product.

摘要： A molding apparatus having a pattern plate provided with vent through bores, a mold flask adapted to be placed on the pattern plate, an up-set frame adapted to be carried by the mold flask, a cover plate covering the upper end opening of the up-set frame, a squeeze plate disposed in the cover and movable into the up-set frame, and compressed air supplying means adapted to introduce compressed air into the space in the mold flask. After filling the space in the mold flask with the molding sand, the compressed air is introduced into the space in the mold flask by means of the compressed air supplying means. The air flows through the molding sand toward the vent through bores formed in the pattern plate so that the molding sand particles are packed and consolidated in the area around the vent through bores. Then, a squeezing is effected on the molding sand by mechanically or pneumatically depressing the squeeze plate so as to form a mold having sufficient molding condition and even compactness, without necessitating jolting action which has been indispensable in the conventional molding apparatus.

摘要： A molding machine has a base, a pattern provided with a plurality of vent bores formed therethrough and mounted on the base, a molding flask arranged to be combined with the pattern, an upset frame superposed to the molding flask, cover means for making an airtight contact at its lower end with the upper surface of the base, molding flask or of the upset frame. Further, compressed air supplying means are provided for supplying compressed air into the closed space defined by the pattern, the molding flask and the upset frame, the space being filled with molding sand. The cover means include a cylindrical member and cover member. The cylindrical member slidably fits to the outside of the cover member in a telescopic manner, and is provided at its lower end with an inwardly projected flange. In operation, the compressed air for compacting the molding sand acts also on the upper surface of the flange of the cylindrical member so as to depress the latter downward into airtight contact with the upset frame or the like. Consequently, the clamping cylinders, which have been essential in the conventional machine for preventing the floating of the cover means, are completely eliminated to simplify the construction of the molding machine.

To determine the period of time for ejecting the first compressed air, the distance of the movement of the squeeze feet toward the pattern plate is measured when the squeeze of the molding sand in the mold space is completed, and the difference between the measured distance and a target distance is calculated. The period is adjusted to be a shorter or lengthened one based on the result of the calculation.
