摘要： PURPOSE: To throw the molding sand with the required throwing energy while keeping the optimum rotational speed for the sand mulling in a sand mulling and feeding blade of a sand mulling and throwing equipment of the molding sand. CONSTITUTION: A rotary shaft 14 is arranged in a cylindrical casing 12, and a plurality of sand mulling and feeding blades 23 on the outer surface of this rotary shaft 14 along the circumferential and longitudinal direction. A feeding hopper 17 of the molding sand is provided on a base end part 13 of the casing 12, and a throwing port 29 of the molding sand is provided on a forward end part 26 of this casing 12. A throwing blade 31 whose diameter is larger than that of the sand mulling and feeding blade 23 is provided on a part of the rotary shaft 14 at the position of this throwing port 29.

摘要： PURPOSE: To control the pressing force of a squeeze rod according to the condition, etc., of molding sand by elevating and lowering plural squeeze rods with plural motor-driven servo actuators and controlling these actuators. CONSTITUTION: The pressing force, etc., of each squeeze rod 12 corresponding to the pattern shape of a pattern plate 1 is decided and torque, etc., of each servo motor 11a is stored in a controller. Then, the squeeze rod 12 is beforehand risen. Further, after charging the molding sand S into a molding flask 16 and a heap-up flask 17 on the pattern plate 1, an electrically driven cylinder 5 is worked and a squeeze plate 14, etc., is descended through an elevating frame 3 and the squeeze plate 14 is abutted on the upper surface of the molding sand S of the heap-up flask 17. Successively, the servo motor 11a is rotated through a driver based on the command of a controller. By this method, the pressing forces of the squeeze rods are made to be mutually different and the descending distance can be controlled.

摘要： PURPOSE: To make it possible to evenly compress the granular material sealed into a casting mold space and to efficiently advance foundry sand to the narrow region of the casting mold by precompressing the surface of the granular material by two stages of pressure, then subjecting the granular material to final compression. CONSTITUTION: The granular foundry molding material is injected in a laminar form into a molding flask so as to cover the casting mold. The pressure fluctuation of a first rate is applied to the surface of the granular material during the prescribed pressure fluctuation/time by using a gaseous medium, by which the first pressure surge is applied thereto and the material is precompressed. The second pressure surge accompanied by the second pressure fluctuation is applied to the surface of the layer of the granular material. The pressure fluctuation time when the second pressure is applied is made greater than the first pressure fluctuation time. The granular material is subjected to a final compressing stage by a mechanical or pneumatic means. As a result, the compaction of the foundry sand in good follow up to the narrow regions may be executed.
