た。However, when press molding is performed by the above-described conventional technique, the upper mold 4 is moved downward as shown in FIG. 4 because the asphalt sheet 3 is impregnated with a resin component or the like. After lowering and pressurizing, when ascending the upper mold 4 upward, the asphalt sheet 3 does not completely peel off from the upper mold 4 and a part of the asphalt sheet 3 is raised with the rise of the upper mold 4. Raised, work 2 and asphalt sea
A space 5 is formed between the asphalt sheet 3 and the work 2, and the asphalt sheet 3 may not be sufficiently bonded to the work 2. Further, even if the release agent is applied to the surface of the upper mold that comes into contact with the asphalt sheet, the function cannot be maintained for a long time, which is not practical.

Is a sub cover 7 which is attached to a dash panel (not shown) of the vehicle by spot welding after the asphalt sheet 3 is bonded, and which has been processed in a predetermined shape in advance. Next, the asphalt sheet 3 is placed on the sub cover 7. Then, the upper mold 4 is lowered, and the asphalt sheet 3 is pressurized and adhered to the sub cover 7. afterwards,
The upper die 4 is lifted upward. At this time, the upper die 4 is pulled upward while blowing air toward the surface of the asphalt sheet 3 from a hole 6 provided in the upper die 4.

The number, diameter, position, and the like of the air supply holes 7 provided in the upper mold 4 may be appropriately determined in consideration of the surface area, thickness, shape, and the like of the asphalt sheet 3. Then, the sub-cover 7 to which the asphalt sheet 3 is adhered is taken out of the lower mold 1, and the press forming operation is completed. Then, the sub cover 7 to which the asphalt sheet 3 is adhered

アスファルトシ−トが確実にワ−クに接着されるので、
その遮音効果は大きい。According to the present invention, since only air is blown onto the asphalt sheet from the upper mold, the asphalt sheet can be securely bonded to the work with a low capital investment. It is more efficient if air is supplied by utilizing the exhaust pressure of the press.
Also, since the mold is merely provided with holes, it can be immediately applied to existing equipment, and its practical effect is extremely large. Furthermore,
As the asphalt sheet is securely bonded to the work,
Its sound insulation effect is great.
