A formwork 3 is placed on a surface plate 2 equipped with a master model 1, and inside the formwork 3 are metal cooling pipes 4.4 through which coolants such as cooling water and oil pass, and rod-shaped members with high thermal conductivity. A large number of elongated metal materials 5, 5 formed from and/or tubular members are charged.

Next, cast resin 91 mixed with easily magnetized metal powder, for example, an epoxy resin containing aluminum powder, copper powder, and iron powder,
When the surface plate 2 and the formwork 3 are magnetized, the cooling tube 4.4 and the elongated members 5, 5 are integrally combined with the casting resin 9, and the iron powder is removed in the casting resin 9. The casting resin 9 is disposed with directionality in the direction of the magnetic field, and then the casting resin 9 is solidified.

で、樹脂型の機械的強度が大きくなるとともに耐熱性が
向上する。The cooling tube and the long metal material are embedded in the resin mixed with easily magnetized metal powder, and the resin is solidified in a magnetic field, so the cooling tube and the long metal material and the resin are integrally bonded.
In addition, since the metal powder that is easily magnetized is arranged in a directional manner, the mechanical strength of the resin mold is increased and the heat resistance is improved.

性°が向上する。Since a large number of cooling tubes and long metal materials are embedded in the resin layer and are integrally bonded to the resin, the resin mold and the molten resin injected into the resin mold can be forcibly cooled. The solidification of the molded product becomes faster and the releasability of the molded product improves.
