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. The cooling tubes 4, 4 are supported by the formwork 3, the long metal materials 5, 5 are arranged in parallel in the formwork 3 via the support member 6, and the surface plate 2 and the formwork 3 are made of metal materials that are easily magnetized. formed by

指向性をもつて配設されるので、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 buried 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. Since the easily magnetized metal powder is arranged in a directional manner, the mechanical strength of the resin mold is increased and its heat resistance is improved.

に冷却することができるので、成形品の固化が早
くなるとともに成形品の離型性が向上する。 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.
