When installing,
If misalignment occurs, it is necessary to peel off the double-sided tape and reposition it again, and if the thickness of the shaped portion 14 is thick, the recess 9 will be in an open state and the desired appearance will not be achieved. It has the disadvantage that the strength becomes weaker when thinner. Further, as shown in FIG. 9, if the protruding length of the shaped portion 14 is shortened, the depth of the recess 9 is not determined, and the skin material 6 is moved up and down when disposing the skin material 6 and when foaming the foam 8. This has the disadvantage that there is a risk of deviation in the direction, which deteriorates the appearance and makes it impossible to obtain the desired shape of the concave portion 9.

The purpose of the present invention is to obtain a desired recessed portion at a desired position in a foam integral with the skin material, to easily and quickly arrange the skin material in the shaping section of the lower die of the foam molding mold, Moreover, to provide a foaming mold for a foam integral with a skin material, which allows wrinkles, etc. on the surface of the skin material to be confirmed from the outside, and allows molding with the recesses sufficiently closed.

[Means for solving problems]

The present invention has been made in view of the above-mentioned problems, and consists of a lower mold in which a shaping part is formed and an upper mold that is matched to the lower mold, and includes the lower mold and the shaping part. In a foaming mold for a skin material-integrated foam, a skin material is disposed along the skin material, and a stock solution of foamed synthetic resin is injected into the inside of the skin material to form a foam integrally with the skin material. The shaping part includes a first shaping part consisting of a protrusion fixed to the lower mold, and a second shaping part provided along the tip of the first shaping part and at an appropriate interval in the shaping direction. It is characterized by being formed from a shaped part.

[Effect]

According to the present invention, the skin material is applied to the first and second parts of the lower mold.
By disposing it in the first and second shaping parts, it is possible to form the desired shape reliably, and it is also possible to check whether wrinkles etc. have occurred in the skin material from the gap between the first and second shaping parts. If wrinkles or the like occur, it can be repositioned immediately, and the skin material on both sides of the shaped part can be brought into close contact with the foam during foam molding. It can be molded into a closed state.
