DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments illustrating the present invention will now be described in detail. Reference numeral 1 denotes one mold that can move forward and backward to hold a molding substrate A having large irregularities on the mold surface, and 11 has a mold surface corresponding to the mold surface of the one mold 1. A surface material B is press-bonded on the surface of a molding base A, which is the other mold which is opposed to the mold 1 so as to be able to freely come and go, and which is held on the mold surface of one mold 1 between the mold surfaces of both molds 1 and 11. Although the basic structure described above is not different from the conventional device for covering a skin material on a molding substrate of this type, in the present invention, in particular, the lower mold as the other mold 11 is used in the present invention. The structure is characteristic. That is, the other mold 11 is arranged at a fixed main mold 12 installed at the center, and is arranged so as to surround the periphery thereof. The movable outer mold 13 is provided with a skin set pin 14 supported by a spring 16 so as to be able to protrude and retract from the mold surface. If necessary, the stationary main mold 12 is also provided with a skin set pin 14a similar to the above.

[0006] The one mold 1 and the other mold 1
1 shows the mold opening state shown in FIG. 2 from the mold opening state shown in FIG. 1 where the mold is opened to form a sufficient space between the two molds 1 and 11 so that the molding base material A and the skin material B can be set. like,
FIG. 3 shows an intermediate skin clamping state in which the outer periphery of the skin material b set between the two dies 1 and 11 by the above-mentioned skin set pin 14 is pressed and clamped by the mold surface of one of the dies 1 that has been advanced. As shown in the drawing, the movable outer die 13 is retracted by a pressure exceeding the supporting force of the spring support mechanism 15 by the one of the dies 1 that has been further advanced, and transitions to a mold clamping state in which the skin material B is adhered to the surface of the molding base material A. It is configured to be.

[0007] The above-described structure is one of the molds 1.
In the mold open state shown in FIG. 1 in which the mold material is held, the molding base material A is held on the mold surface of one mold 1, and the skin material B is brought above the other mold 11, and the outer periphery thereof is used as the mold of the movable outer mold 13. This skin material b is set on a skin set pin 14 provided on the surface and a skin set pin 14a provided on a portion of the mold surface of the fixed main mold 12 where a post hole is to be drilled as required. When the setting of the molding base material A and the skin material B is completed in this way, one of the dies 1 is moved to the outer peripheral portion 13
If it is advanced to the position where it comes into contact with the inner circumference of the mold surface,
The outer periphery of the skin material B set between the two molds 1 and 11 by the skin set pin 14 is pressed against the mold surface of the movable outer mold 13 by the mold surface of one of the molds 1 that has been advanced, and then clamped. If the mold 1 of FIG.
When the pressing force of one advanced mold 1 exceeds the supporting force of the spring support mechanism 15, the movable outer mold 13 is retracted while maintaining the clamped state, and the movable outer mold 13 is moved to the final position. When the mold substrate is retracted to a position where the pressing force of one of the molds 1 is held on this mold surface, the fixed base mold 1
A surface material B is attached to the mold surface of the other mold 11 composed of the movable mold 2 and the movable outer mold 13, and when the mold is in a clamped state, the surface material B is adhered to the surface of the molding base material A. During this time, the skin material B is pressed by the surface of the molding base A with its periphery clamped, so that even if the molding base has a large unevenness on the surface, there is almost no skin floating failure As a result, it can be accurately and easily adhered to the surface of the molding substrate A without wrinkling.

Further, the skin set pin 14 is connected to the other mold 1
1, there is no need to provide a skin material clamping device outside the mold because the movable outer mold 13 is a part of the mold 1. In addition, the entire apparatus can be made compact. Further, the movable outer mold 13 is supported by the spring support mechanism 15 and is always in the raised position.
If the apparatus is lowered by pressurization, the apparatus can be provided simply and inexpensively, and it is advantageous in terms of maintenance.

As is apparent from the above description, the present invention relates to one mold for holding a molding substrate on a mold surface and the other mold having a mold surface corresponding to the mold surface of this one mold. A skin material is applied to a molding base material in which a skin material is pressure-bonded to the surface of a molding base material held between two mold surfaces and held on one mold surface so as to be able to freely contact with and separate from each other. In the apparatus, the one mold is movable forward and backward, and the other mold is a split mold comprising a fixed main mold and a movable outer mold movable around the periphery of the fixed main mold, and a skin set on a mold surface of the movable outer mold. A pin is provided, and the outer periphery of the skin material set between the two dies by the above-described skin set pin from the mold open state in which a sufficient space is formed between the two dies with the one mold and the other mold. Through an intermediate skin clamp state pressed by the mold surface of one of the molds advanced, Since the movable outer die is retracted by pressing with one of the molds and the skin material is shifted to a mold clamping state where the skin material is adhered to the surface of the molding substrate, the molding substrate has large irregularities on the surface However, the skin material can be accurately applied without wrinkling, and the skin material can be cut to a size that is not wasteful, so that it is economical, and the skin material is clamped outside the mold. Since there is no need to install equipment,
There is an advantage that the entire apparatus can be made compact. Therefore, the present invention is extremely large in that it contributes to the development of the industry as a solution to the problems of the conventional apparatus for covering the surface of a molding material with a skin material.
