摘要： PROBLEM TO BE SOLVED: To provide a structure reforming method which surely prevents the surface of a casting and a casting defect from being communicated with each other. SOLUTION: A rotary tool 20 having a base part 31, and a projecting part 32 extending by inclining from a front end 31a in an axial line direction of the base part 31 in a direction approaching a rear end 31b in the axial line direction as the projecting part protrudes in the radial direction of the base part 31 and progresses in one R1 of the peripheral direction around the rotary axis L1 is used to conduct friction stirring by rotating the rotary tool 20 in the one R1 of the peripheral direction. Thereby a fluid 38 with a softened part plastically flowing is formed in a prepared hole 36. The fluid 38 moves in the rotating direction R1 and also in the axial line direction Z1 and thereby the fluid 38 is made easier to stir and the amount of the fluid 38 plastically flowing can be increased. As a result, the fluid 38 can increase the solidified reforming layer 39 and can increase the amount of dissipation of the casting defects, and the inner peripheral surface of the prepared hole of the casting 19 is more surely prevented from being communicated with the casting defect.

摘要： PROBLEM TO BE SOLVED: To prevent the oxidation of molten metal in a stoke by shutting off the outer air and to improve the quality of a casting by arranging a means for automatically covering to an opening hole at the upper part of the stoke after shifting a die and supplying inert gas in the stoke. SOLUTION: At the time of coming a sub-truck to a prescribed position, an elevating/lowering cylinder 22 is extended and a cover 21 is lowered and covered on the opening hole 6a at the upper part of the stoke. At this time, the lower surface of the cover 21 is press-attached to seal packings 25, 26 arranged in grooves on the upper surface of the stoke 6 and sealed. Successively, inert gas is supplied into the upper space of the stoke 6 through an inert gas supplying hose 24 and sealed in the stoke 6. The seal packings 25, 26 are brought into contact with the lower surface of a lower die and worked so as to improve the sealness. The durable term is lengthened by using a graphite base packing to the seal packing 25 and a metal-made packing to the seal packing 26. In such a way, the prevention of temp. lowering of molten metal and the stabilization of the temp. can be obtd. by using the cover 21.

摘要： PROBLEM TO BE SOLVED: To reduce a gap between the lower surface of a lower die and the laying surface at a fixed plate side, to prevent molten metal from being infiltrated into the gap and to prevent a packing from coming into contact with the molten metal by inserting the packing into an annular groove part. SOLUTION: The annular groove part 40A is formed on the lower surface 21A of the lower die or the laying surface 7A at the fixed plate side for laying the lower die 2 or on the both of the lower surface 21A of the lower die and the laying surface 7A at the fixed plate side. This annular grove part 40A is formed so as to surround the opening hole part 32A at the upper part of a stoke 3A. Then, the packing 50A is inserted into the annular groove part 40A. In such a way, the gap 6A between the lower surface 21A of the lower die and the laying surface 7A at the fixed plate side can be reduced by inserting the packing 50A into the annular groove part 40A, and the molten metal is prevented from being infiltrated into the gap 6A.

摘要： PROBLEM TO BE SOLVED: To improve the sealability between a mold and a fixed plate during the casting, to collect dropped slug without scattering, to enable the finish- cleaning after oxide scales are removed if an air blow means is arranged on the downstream side by pressing a scraper against a lower side of a mold while the mold is moving to remove and clean oxide scales such as aluminum adhered to the lower side of the mold. SOLUTION: A truck is moved in a horizontal direction along a rail while holding a mold with a casting under solidification therein. When a lower side of the mold under movement is moved sliding on a tip 10a of a scraper 10, oxide film of aluminum on the lower side of the mold adhered during the casting is scraped, and dropped on a receiving pan 1 therebelow, and collected in a U-shaped collection groove 6 along an inclined bottom wall 5. The mold after passing through the scraper 10 is finish-cleaned by blowing the air ejected from a nozzle 3a against the lower side of the mold when the mold passes the position of an air blow pipe 3.
