FIG. 1 is a sectional view showing a state in which a protrusion is provided directly below the protrusion of the lower die of the mold of the present invention, and a thin film for preventing protrusion is placed on the protrusion. FIG. 2 is an enlarged sectional view showing the state in which the thin film is placed on the protruding portion of FIG. 1. FIG. 3 is an enlarged cross-sectional view showing the state in which the thin film of the protruding portion of FIG. 1 is brought into close contact with the upper mold by the foaming pressure of the synthetic resin mixture. Figure 4 shows the upper and lower molds showing the state in which the thin film placed on the protrusion directly above the protrusion of the upper mold is tightly attached to the lower mold by the foaming pressure of the synthetic resin mixture. Cross-sectional view. FIG. 5 and FIG. 6 are state diagrams showing a cutting section provided for adhering a thin film to a mold in order to prevent wrinkles in a curved portion. 1...Lower die, 2...Upper die, 3...Protrusion for placing film, 4...Upper die/lower die protrusion, 5...
