Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a foam with an integral skin material, and to explain it in more detail, it includes a lower mold in which a shaped portion consisting of ridges is formed, and a mold on the lower mold. A skin material is placed along the lower mold of the foam molding mold, which is made up of an upper mold to be matched, 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 present invention relates to a skin integral foam formed by molding.

[Conventional technology]

Foams with integral skin materials have been known for use in seats of vehicles, etc., and these foams with integral skin materials 5 are used for the seat cushion 2 and seat back 3 of the seat 1, as shown in FIGS. 4 and 5. Applied. A shaped recess 9 is formed on the side of the skin integrally foamed body 5 .

The integral skin foam 5 having this recess 9 is the sixth
Foam molding is performed using a foam mold 11 as shown in the figure. A shaping section 14 consisting of a protrusion is formed on the lower mold 12 of the foaming mold 11, and the sewing section 7 of the skin material 6 and other parts to be shaped are aligned with this shaping section 14 to form the skin material 6. Arrange.
In this case, the skin material 6 is attached to the shaping part 14 with double-sided tape or the like so that it does not shift from the shaping part 14, and then the stock solution of foamed synthetic resin is injected into the lower mold 12 which is inside the skin material 6, and the upper mold 13 are mold-matched and foam cured, and a foam 8 integrated with the skin material 6 is foam-molded to form a skin material-integrated foam body 5 having a concave portion 9 shaped by the shaping section 14.
This is done so that you can obtain the following.

[Problem that the invention attempts to solve]

However, when forming the conventional skin material-integrated foam 5, it is difficult to securely attach the skin material 6 to the shaping part 14 of the foam mold 11. When installing,
If misalignment occurs, it is necessary to peel off the double-sided tape and reposition it again, and if the surface of the skin material 6 becomes dirty with double-sided tape, etc., or if double-sided tape is not used, This had the disadvantage that the skin material 6 was in a floating state, making it impossible to obtain the desired shape of the skin material integrated foam 5 with the recesses 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, it is an object of the present invention to provide a foam integral with a skin material that is free from the risk of staining the surface of the skin material.

[Means for solving problems]

The present invention has been made in view of the above-mentioned problems, and includes a lower mold formed with a shaped portion consisting of a protrusion, and an upper mold that is matched to the lower mold. A skin material-integrated foam is formed by disposing a skin material along the skin material, injecting a stock solution of foamed synthetic resin into the inside of the skin material, and foam-molding the foam integrally with the skin material. It is characterized in that it has a clip for attaching the material to the shaping part, and the foam is foam-molded with the clip sandwiching the skin material.

[Effect]

According to the present invention, the skin material can be clipped to the shaping part of the lower mold, and the desired shape can be formed reliably, and if wrinkles etc. occur in the skin material, it can be immediately disposed. It can be reinstalled and there is no risk that the surface of the skin material will be soiled by adhesives such as double-sided tape.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the skin-integrated foam according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an outline of an embodiment of the skin-integrated foam body according to the present invention. A recess 2 formed on the side of the skin integral foam 21.
5 is formed. Then, a clip 2 is attached to the inside of the skin material 22 on the foam 26 side of this recess 25.
7 is provided. The skin material 22 is formed from a skin 23 on the front side and wading 24 on the back side.

The clip 27 is made of a synthetic resin material such as acrylic resin or nylon, and has an appropriate width. is foam molded.

FIG. 2 shows a skin material integrated foam 2 according to the present invention.
1 foam mold 31 is shown, and this foam mold 31 consists of a lower mold 32 and an upper mold 33 that is fitted to the lower mold 32. A shaped portion 35 is formed. Further, a core mold 34 for holding down the end of the skin material 22 is provided at the mold matching portion of the lower mold 32 and the upper mold 33.

Therefore, when disposing the skin material 22 on the lower mold 32, the part of the skin material 22 to be shaped is placed on the lower mold 32.
The skin material 22 can be attached and fixed to the shaping part 35 with the clips 27.

After disposing the skin material 22 on the lower mold 32, the upper mold 33
If the molds are matched, a stock solution of foamed synthetic resin is injected through the injection port 36 of the upper mold 33, and the foam is cured to form the foamed body 26, a skin material-integrated foamed body 21 as shown in FIG. 1 can be obtained. I can do it.

[Effect of idea]

The above is the structure of one embodiment of the skin material-integrated foam according to the present invention. According to this structure, the skin material can be securely attached with clips along the shaping part of the foam mold, The work of arranging the skin material can be done extremely easily and quickly, and even if wrinkles occur in the skin material during the work of arranging the skin material, it can be easily repositioned. The shape of the skin can be formed by uniformly shaped recesses without the risk of contamination, and since the clips are still holding the skin material even after the foam is molded, the shape retention of the skin material can be improved. A material-integrated foam can be obtained.
