For the interior of an elongated casting to form an elongated core, it is ultimately necessary to form a cavity of elongated core structure. However, the support is needed when the strip-shaped mold core is formed, the support mode is that the iron support is formed at the bottom of the mold core, but the support is made of iron, so that when molten iron is poured, the support can be melted along with the high temperature of the molten iron, and the mold core can be dropped; a group of support claws formed by graphite rods are horizontally inserted on the vertically arranged mold core, and the support claws provide strength for the strip mold core; then injecting molten iron into the sand box for solidification; after solidification, a cavity is formed at the position of the strip-shaped mold core part, the graphite rod is disassembled due to the fact that the outside of the graphite rod is wrapped by molten iron, and the through hole is formed at the position of the graphite rod and communicated with the position of the original strip-shaped mold core, so that the strip-shaped through hole required by the casting is formed finally.
As can be seen from the above process, the through-holes of the long castings are realized by the core frame formed by the support claws and the frame formed by the graphite rods. It should be noted that the position degree of the through holes is completely determined by the position degree of the core skeleton, the parallelism of the graphite rod, the connection angle of the skeleton and the graphite rod and the like, so that the quality of the casting is ensured. For example, if a casting needs to form inclined through holes, the angle between the skeleton and the graphite rod in the core skeleton is ensured.
In the prior art, the connection of the framework and the graphite rod needs to be welded by a large amount of manpower, and the defects that the welding accuracy cannot be ensured even if most of the manpower is adopted, the manual error is easy to occur, and the rejection rate is high; therefore, welding with higher accuracy is required to be achieved by means of special tools, and labor is saved.
