Description

  The present invention relates to a casting apparatus that includes a melting furnace having a hot water outlet for melting a metal to form a molten metal and pouring the molten metal into a mold to produce a cast product.

  Conventionally, for example, when manufacturing an industrial product or the like with a cast product, the metal is melted in a melting furnace to form a molten metal, and the cast product is manufactured by pouring the molten metal into a mold disposed below the melting furnace. With respect to the casting apparatus, for example, a technique described in Patent Document 1 is disclosed (for example, see Patent Document 1).

Thus, when manufacturing industrial products etc. with cast products, it is common to pour the molten metal into the mold gently in a short time and fill the molten metal to every corner of the mold to obtain a healthy and homogeneous metal structure. For this reason, when pouring molten metal into a mold, the mold is moved, the molten metal is poured over a wide range, and the molten metal is poured gently in a short time.
JP 2001-304767 A

  However, since the molten metal poured into the mold is deprived of heat from the contact portion of the mold and gradually solidifies from the contact portion, when the molten metal solidifies as a cast product, when the inside of the cast product becomes the final solidified part, There was a problem that the molten metal could not be replenished to the final solidified portion, a cast hole was formed in the final solidified portion, making it difficult to produce a homogeneous cast product, and the strength of the cast product was reduced.

  On the other hand, when pouring while moving the mold, it is possible to transfer the molten metal to the mold quietly in a short time, but the molten metal transferred to the mold vibrates as the carriage moves, so Since hot water wrinkles and the like due to vibrations are likely to occur, there is a technical need to be able to manufacture a cast product with a healthy metal structure by suppressing the shaking of the molten metal after pouring.

  In addition, when casting a metal material having a low melting point and easily oxidized characteristics, or when manufacturing a casting that does not allow small defects in quality, the space for melting and pouring is reduced, for example, in a reduced pressure state. There is a case where casting is required. In such a case, since it is difficult to transfer the molten metal while relatively moving the melting furnace and the mold, such technical technical demand is particularly great.

  The present invention has been made in consideration of such circumstances, and suppresses the formation of a void in a cast product when a molten product melted in a melting furnace is poured into a mold to produce a cast product. It is an object of the present invention to provide a casting apparatus capable of producing a cast product having a healthy metal structure.

In order to achieve the above object, the present invention proposes the following means.
The invention according to claim 1 is a casting apparatus comprising a melting furnace for melting a metal to form a molten metal, and a mold for pouring the molten metal into a cast product by pouring the molten metal below the melting furnace. And a cooling means capable of moving relative to the mold and capable of contacting the mold.

According to the casting apparatus of the present invention, the casting apparatus is provided with a cooling means that is movable relative to the mold and cools the mold in contact with the mold, so that the molten metal is poured into the mold at an appropriate timing. The mold can be cooled by advancing the cooling means.
As a result, it is possible to heat the mold before casting in order to facilitate filling of the molten metal into the mold.
Also, when pouring the molten metal into the mold before pouring the molten metal into the mold, the molten metal can be cooled at a desired timing after the pouring of the molten metal into the mold is completed. A sound metal structure can be formed in the casting.

  The invention according to claim 2 is the casting apparatus according to claim 1, wherein the cooling means comprises a cooling jacket through which a cooling medium can flow, and can be brought into contact with the lower part of the mold. Characterized by

According to the casting apparatus of the present invention, since the cooling means is the cooling jacket, it can be easily separated from the outside by circulating the refrigerant inside the cooling jacket. Exposure to the atmosphere is suppressed.
As a result, it is possible to easily control the refrigerant and use a refrigerant having a large cooling capacity.
In addition, since the cooling jacket comes into contact with the lower part of the mold where the molten metal first starts solidification to cool the molten metal held in the mold, it is possible to stably perform directional solidification of the molten metal. In addition, it is possible to manufacture a cast product with few internal defects.
