| PURPOSE: To prevent occurence of brittle rupture in a metal mold for centrifugal casting of cast iron pipes due to occurrence of heat cracks by making the mold of cast steel of a specific compsn. followed by hardening and tempering. CONSTITUTION: A metal mold for centrifugal casting of cast iron pipes is made of steel contg. C; 0.05W0.22%, Si; 0.2W0.8%, Mn; 0.5W1.5%, P<0.04%, S< 0.03%, Ni; 0.05W1.5%, Mo; 0.15W0.6% and V; 0.03W0.12%. By hardening and tempering the mold, occurence of shattered cracks due to repeated thermal impacts is prevented. Accordingly, occurrence of brittle rupture due to propagation of the cracks is also prevented, and hence the endurance life of the mold is elongated. COPYRIGHT: (C)1979,JPO&Japio | ||||||

| PURPOSE:To prevent warp according to cooling of a core extruding from a metallic mold at the time of extrusion the hollow-state core with the metallic mold. CONSTITUTION:By pushing core sand S into inner part of the metallic mold 1 from one end of the heated metallic mold 1 with reciprocative movement of a piston 7, the hollow-state core W is formed, and the core W is extruded from the other end of metallic mold 1 according to the reciprocative movement of piston 7. The core W extruded from the metallic mold 1 is pushed into a cooling jig 13 and outer peripheral face of the core W is forcedly cooled with the cooling jig 13 while restricting this with cylindrical core guiding face 17. | ||||||

| PURPOSE: To make the molding of a thin-walled hollow core easy by providing a discharge port to the lower part of the blow-in port in the upper part of a pair of heated and separable metal molds thereby blowing shell and from the upper part and discharging the same from the lower part. CONSTITUTION: The movable metal mold 8 of metal molds 7, 8 having been heated with a heater is clamped to a stationary metal mold 7 by a cylinder 19. Next, the sand discharge port 13 of the metal molds 7, 9 is closed by a cover 48 with a lever and a blow head 35 is lowered by a cylinder 33 and is allowed to contact closely with the blow-in port. Thence, the compressed air in a tank 41 is supplied to the blow head 35 to blow shell sand into the metal molds 7, 8, after which the blow head 36 exhausts the compressed air and ascends. Next, the cover 48 of the sand discharge port 13 is opened by the lever to allow the unfired shell sand to fall by gravity. Thence, when the metal mold 8 is parted from the metal mold 7 by the cylinder 19, the hollow core moves rightward together with the metal mold 8. The projecting rods 27, 28 of a frame 3 abut on a connecting plate 25 and ejector rods 21, 22 eject the hollow core from the metal mold 8. COPYRIGHT: (C)1981,JPO&Japio | ||||||
