[0003] Such a casting method has been used for a long time, but in recent years, a shell mode method has been adopted as a molding method of a mold which is strong and can be formed quickly. In this shell mode method, a mold model is preheated, and molding sand made of silica sand or the like using a thermosetting synthetic resin such as a thermosetting phenol resin as a binder is sprinkled, and the heat of the resin is heated. This is a casting method in which a rigid main mold and a core are formed by a hardening action, and a molten metal is poured into an inner space of a mold formed by combining these to form a casting.

The method of taking out the core 3 in the above embodiment will be described in further detail. First, as shown in FIG. 1, a flexible material is formed in the opening 7 of the hollow portion 1 of the casting 2 where the core 3 remains. When the high-pressure water supplied from the high-pressure pump 4 is injected to face the injection nozzle 6 at the tip of the hose 5, the core 3 in the opening 7 is crushed by the injection force and discharged from the opening 7 together with the water. You. Then, as shown in FIG. 2, when the flexible hose 5 and the injection nozzle 6 are further inserted into the inside, the inner core 3 is also crushed for the same reason and discharged from the opening 7 together with the water. In this way, by inserting the flexible hose 5 and the injection nozzle 6 sequentially into the back, all the cores 3 in the hollow portion 1 can be completely removed, and at the same time, the inner surface of the hollow portion 1 can be cleaned cleanly. do it,

FIG. 5 relates to an apparatus embodying the above method, in which an opening 7 of a casting 2 continuously fed by a conveyor 8 is connected to a high-pressure pump 4 via a flexible hose 5. A device fixed to a conveyor 8 with a locking tool 9 so as to face forward of an injection nozzle 6 is shown. Insertion of the flexible hose 5 and the injection nozzle 6 from the opening 7 of the casting 2 into the inside may be performed by a separate mechanical operation or by hand, and is not particularly limited. Further, instead of transferring the casting 2 by the conveyor 8, another transfer device may be used, and when the amount is small, the transfer may be performed one by one.
The transfer means and the fixing means of the casting 2 are not limited at all. Thus, the device of this embodiment is minimal,
A high-pressure pump 4 that generates high-pressure water and supplies the high-pressure water from a discharge side thereof; and a flexible hose 5 that guides the high-pressure water supplied from the high-pressure pump 4 and that can be inserted into the hollow portion 1 where the core 3 remains. It suffices to provide an injection nozzle 6 that is provided at the tip of the flexible hose 5 and that injects high-pressure water that can be inserted into the hollow portion 1 where the core 3 of the casting 2 remains. The means for generating high-pressure water by the high-pressure pump 4 may be any means.

In the above-described method and apparatus for removing a core, the high-pressure water has a pressure that can pulverize the hardened core sand, but is desirably in a range that does not damage the metal surface of the casting. Specifically, it is usually in the range of 20 MPa (200 kgf / cm 2 ) to 400 MPa (4000 kgf / cm 2 ), more preferably in the range of 30 MPa to 300 MPa, though it varies depending on the type of metal of the casting.
However, since these water pressures also affect the distance between the injection nozzle 6 and the core 3, it is generally difficult to limit the water pressure. For example, in the case of 100 MPa, the shell mode from the tip of the injection nozzle 6 to about 5 cm It is possible to pulverize the core 3 made by the method.
In the case of 0 cm and 300 MPa, respectively, it can be up to about 15 cm. However, as described above, depending on the metal of the casting 2, the surface strength is weak and the inner wall surface is damaged. Therefore, the metal is appropriately selected so as to match the type and shape of the metal of the casting 1.

According to the present invention, since high-pressure water can be injected from the opening side of the hollow portion of the casting to the back by the flexible hose and the injection nozzle at the tip thereof, the present invention is applied to a casting having a hollow portion having a long depth. There are advantages that can be done. And, even when the hollow part of the casting is bent or meandering, the flexible hose itself also bends and meanders in accordance with the bending and meandering by pushing in from the opening side, and adapts to the end. Since it can enter, it can be applied to hollow portions of various shapes. or,
It can be applied even when the length of the hollow portion is long.

Also, since the core removing device is a device including a high-pressure pump, a flexible hose, and a jet nozzle for jetting high-pressure water provided at the tip of the flexible hose,
Since the flexible hose and the injection nozzle can be inserted into the hollow portion of the casting, even when the depth inside the hollow portion is long, the inner core can be removed cleanly. In addition, not only straight hollow parts but also bent or meandering hollow parts are bent and meandered according to the shape of these hollow parts, so even deep cores can be inserted. Can be removed. Further, the inner surface of the hollow portion is not damaged due to the flexibility of the hose.
