Filed: 2019-01-23
Abstract: To provide a sand-mold caster for a differing-shaped tube allowing for positioning and setting a core 4 to and in molds 2a, 2b with easiness and simplicity.SOLUTION: A sand-mold caster A for a differing-shaped tube consists of upper and lower molds 2a, 2b in which sand a is molded in metal frames 1a, 1b, a core 4 inserted in a cavity 3 of the upper and lower molds laid together, and means for fixing both ends of the core respectively to the metal frames. The core 4 is provided by molding sand a around a core-metal 5 and fixing a horizontal rod 7 to one end of the core-metal 5 at a central portion thereof. The fixing means at one end of the core 4 supports/fixes one end of the horizontal rod 7 at between upper and lower long-nosed portions 8, 8 on a side face of the metal frame 1a, 1b by screw jacks 9 and supports/fixes the other end of the horizontal rod 7 to the other long-nosed portions 8, 8 on the side face of the metal frame 1a, 1b, with the other end of the core-metal 5 fixed to a side face of the metal frame 1a by a fixed clamp 12. In this supporting/fixing state, the inclination angle (attaching angle) relative to the other end of the horizontal rod 7 can be adjusted by the upper and lower screw jacks 9 at the one end of the horizontal rod, and hence it is comparatively easy to rotate/fix the core in a cylindrical shape or the like about its axis without restriction.SELECTED DRAWING: Figure 1
