くなる。However, in the case of a mold for forming an aluminum wheel, a gate for filling the molten metal into the cavity is provided at a central portion, a large amount of heat is released from the molten metal at the time of casting. In a part receiving heat from the outer periphery, such as a casting hole for use, the temperature is higher than in other parts.

均等になっていなれけばならない。In general, in die casting or the like, an aqueous solution in which a mold release agent is mixed is sprayed in the form of a mist on the surface of a mold, and the moisture removes heat from the surface of the mold and evaporates, causing solids to adhere to the surface of the mold.
Heat insulation during pouring and prevention of seizure during mold release.
In order to perform good casting, it is necessary to uniformly apply the release agent, but for that purpose, the temperature of the mold surface after release must be uniform.

問題があった。If there is a locally high temperature, it is necessary to apply a large amount of the aqueous solution only to that portion, but it is difficult to locally control the amount of spray in actual operation. Therefore, a hole for cooling is drilled through the mold at the part where the temperature becomes high, and water is passed.If this reduces the dimension of the hole between the water hole and the cavity in terms of structure, the mold release agent becomes too cold. However, there is a problem in that the mold does not adhere well, or a mold crack occurs between the water hole and the cavity due to thermal stress, and the mold life is shortened.

By preventing the local temperature rise of the mold at the place, the cooling time of the casting is shortened, and the temperature of the mold is not uniform, and a good cast product is obtained, and the generation of thermal stress is further reduced. The purpose is to extend the life of the mold.

状の銅棒１５が挿入してある。When the molten metal 11 filled in the cavity 10 solidifies, heat of solidification and sensible heat are released. In particular, since the amount of heat released from the vicinity of the gate portion 8 and the cavity surface 13 having a cast-out shape is large, it is necessary to make the cooling medium passage 12 close to cool this heat. Mold cracking may occur due to poor adhesion and thermal stress. Therefore, in the present invention, as shown in FIG.
A copper rod 15 having a high thermal conductivity and having a circular cross section is inserted therein.

るためである。A hole 16 communicating with the cooling medium passage 12 is formed from the cavity surface 13 side.
A mortar-shaped hole 18 is formed on the side, and the section is continuously connected to the circular hole 16. The root of the copper rod 15 is formed as a flange portion (locking member) 20, and the flange portion 20 engages with the joint between the mortar-shaped hole 18 and the cylindrical hole 16. The stop has a stepped shape. This is because the copper rod 15 is heated when the molten metal is cast into the cavity 10 after the copper rod 15 is first mounted in the hole 16 and the copper rod 15 contracts when cooling the mold after filling the molten metal. , By expanding and contracting the copper rod 15 by heating and cooling
This is to prevent the copper rod 15 from sliding down to the cooling medium passage 12 side.

It is important to mount the copper rod 15 so as to be fitted to the same. By doing so, the molten metal 1 reaching the hub portion 14
The heat of 1 is transmitted to the copper rod 16 and is transmitted through the copper rod 15 having a high thermal conductivity to cool the portion in contact with the cooling medium, thereby promoting the cooling of the hub portion 14.

ようになっている。Further, after the copper rod 15 is attached to the hole 16,
After the copper rod 15 is completely fixed by performing the build-up welding 17 in the mortar-shaped hole 18, the cavity surface 13 is subjected to finish processing. At this time, the welded cavity surface 13 is polished so as to be appropriately smooth. . The tip of the copper rod 15 is formed in a semicircular shape in order to take a large heat receiving area, and projects into the cooling medium passage 12 so that the tip of the copper rod 15 is cooled by the cooling medium. When the tip is cooled, a temperature gradient is formed in the copper rod 15 and a large amount of heat stored in the hub 14 can be removed by the high thermal conductivity.

The distance at which the tip of the copper rod 15 protrudes may cause a large flow resistance in the cooling medium (generally, water is preferable, but oil or liquid N2 may be used) flowing in the cooling medium passage 12. A position that does not exist is desirable.

At this time, since the cooling medium continuously flows through the cooling medium passage 12, the tip of the copper rod 15 is cooled, and a temperature gradient is formed in the copper rod 15. The heat stored in the hub portion 14 can be removed via the copper bar 15 due to the high heat transfer coefficient of the copper bar 15.

する効果もある。According to the present invention, a lower mold for casting an aluminum wheel having a casting hole at the center is divided into a design mold and a backup mold in a disk shape, and a cooling medium passage is provided on the divided surface. At the same time, a copper rod with a protruding tip is arranged so as to face the cooling medium passage, and the heat stored in the hub part is removed by the high heat conduction of the copper rod, so that the local area of the mold is reduced. Unnecessary temperature rise can be prevented. As a result, uniform release of the release agent can be obtained when the release agent is sprayed. Further, by setting the mold surface temperature to an appropriate temperature, the release efficiency of the release agent is extremely improved, and casting defects are obtained. This has the effect of reducing the consumption of the release agent as well as reducing the amount of the release agent.
