The local cooling of the mold was designed by taking into account the arrangement of cooling water passages in a normal cooling method so that the mold temperature fell within the range. However, forming cooling water passages using such a normal cooling method is extremely difficult, especially when forming an object with a complicated shape, such as forming a water channel in a very small area. For this purpose, we rely on macroscopic cooling methods that take into account cooling in extreme locations.
A highly accurate and uniform cooling effect cannot be obtained.

In order to make extreme cooling possible with extremely easy work, a cylindrical heat exchange chamber is provided in which the tip of the metal tube 1 is inflated to rapidly diffuse the compressed refrigerant liquid, and the compressed refrigerant liquid is introduced. A metal tube 2 that is extremely thinner than the diameter of the heat exchange chamber is provided inside the metal tube 1, and an opening of the metal tube 2 is installed near the inner bottom surface of the heat exchange chamber, and these are configured to perform heat exchange. By forming an extremely small heat exchange device that enables cooling, the cooling device is embedded in the part of the mold that is to be cooled at a local area, and the cooling system is used to cool each local area of the mold, and as a result, it is intended to compensate for normal cooling. This allows the mold to be cooled uniformly and with extremely high precision.

The present invention will be explained in detail with reference to the drawings. FIG. 1 is a side sectional view of one embodiment of the present invention. Diameter φA
A metal tube 2 having a diameter φB which is extremely smaller than the diameter of the large metal tube 1 is provided inside the metal tube 1, and the tip portion 1a of the metal tube 1 is expanded to a desired length L to provide a heat exchange chamber 1c having an outer diameter φC. , an opening 2a of the metal tube 2 is provided near the inner bottom surface 1b of the heat exchange chamber 1c to constitute a local cooling device 1c . The compressed refrigerant liquid 3 is sent to the metal tube 2 and rapidly diffused into the heat exchange chamber 1c from the opening 2a of the tube to perform heat exchange. FIG. 2 is a side sectional view of one implementation of cooling in which the local cooling device 1c of FIG. 1 is embedded in a convex portion of a mold. The mold 5 is cooled in the usual macroscopic manner by the cooling channel 6, but the protruding convex portion 5 of the mold 5
A local cooling device 1c is buried in the portion a to perform local cooling of that portion 5a. The compressed refrigerant liquid 3 obtained by the compressor 4 is sent to the metal tube 2 (see Figure 1), and the refrigerant 3b after heat exchange in the extreme cooling device 1c is recovered to the compressor 4 and converted into refrigerant liquid 3. Then, it is sent to the heat exchange chamber 1c via the metal tube 2, and the heat exchange cycle is performed.
