ていた。(Problem to be solved by the invention) The mold 53 used in this molding method is of various types, such as a wooden mold, a plaster mold, a resin mold, and a metal mold. The molds are used differently, and the wooden mold 9
Gypsum molds are inexpensive and easy to manufacture, and are widely used primarily as prototype molds for small-scale production. However, when used repeatedly, these wooden molds and plaster molds are susceptible to rapid temperature changes such as rapid heating and cooling, and breakage occurs after 20 to 30 uses.
It becomes unusable. On this point, as a result of advances in the improvement of epoxy resin materials in recent years, resin molds can be manufactured with great strength, are easy to mold, and are
It can withstand ten thousand uses and can be produced at a low price, so its range of use is expanding. but,
This resin mold is manufactured using epoxy resin and glass cloth as the main raw materials, mixed with silica particles as a reinforcing agent, so the entire mold is made of heat insulating material, as shown in Figure 2. There is a problem in that the temperature of the mold cannot be controlled when molding the plastic shown above, and for this reason, molds with good heat conductivity are currently often used as molds for vacuum molding. However, in order to manufacture molds made of aluminum, etc., it is necessary to use cutting machinery such as copy milling machines and numerical control methods, which increases the manufacturing cost.
Furthermore, there is a drawback that it takes a considerable number of days to manufacture, and it has been desired to improve the thermal conductivity of the resin mold, which is inexpensive and easy to manufacture.

である。(Means for Solving the Problems) The present invention was devised in view of the above-mentioned conventional problems, and aims to provide a molding die that has good heat conduction, is easy to manufacture, and is inexpensive. The gist is that a mold for plastic molding is made by embedding multiple pipes in an excellent heat conductive layer formed using aggregates such as metal powder and carbon powder. In addition, the manufacturing method is to use a semi-sludgy material obtained by stirring and mixing aggregates such as metal powder and carbon powder with a binder containing components that evaporate during the hardening process. A heat conductive layer with excellent heat conductivity is formed on the surface of the replica mold by injection or lamination on the surface, and a plurality of pipes through which cold water or hot water can pass are buried in the heat conductive layer, and The method is characterized in that the heat transfer layer is hardened by applying pressure.

的強度の大なる成形型とすることができる。(Function) There are multiple pipes buried in the heat transfer layer, and since the heat transfer layer is made of metal powder, carbon powder, etc. as aggregate, the heat conduction is effective. By passing cold water or hot water through the pipe, the heat of the cold water or hot water is well transmitted through the heat transfer layer, and the heat is well transmitted to the plastic, resulting in good temperature control. This makes it possible to mold plastic products. In addition, in the manufacturing method of such molds, an adhesive containing ingredients that evaporate during the hardening process, such as alcohol, is mixed with the aggregate of metal powder and carbon powder, and the mixture is stirred to form a semi-sludgy mixture. This can be injected or laminated onto the surface of a replica mold to easily form a heat transfer layer, and when forming this heat transfer layer, multiple pipes can be easily buried within the heat transfer layer. Then, by pressurizing and hardening the heat transfer layer, the evaporated components are removed and the metal powder and carbon powder are firmly bonded, resulting in a mold with high mechanical strength.
