（産業上の利用分野）
この発明は、表面に軟質の表皮材が積層された樹脂成形
品の成形方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for molding a resin molded product having a soft skin material laminated on its surface.
（従来の技術）
例えば、自動車のコンソールボックスは合成樹脂による
一体成形品が通常であるが、質感向上のため、最近では
表面に軟質の表皮材を貼り付けたものも開発されている
。第４図はこういったものにおける表皮材の貼り付けの
手法を示すものである。(Prior Art) For example, automobile console boxes are usually integrally molded from synthetic resin, but recently, console boxes with a soft skin material pasted on the surface have been developed to improve texture. FIG. 4 shows a method of pasting the skin material on such items.
成形にあたり、表皮材２は一方の金型５にセットされ、
この後両金型５．６間にパリソン（基材１）を押出す。During molding, the skin material 2 is set in one mold 5,
After this, the parison (base material 1) is extruded between both molds 5.6.
この場合、基材１は成形コストとの関係からオレフィン
系樹脂原料が使用される。In this case, an olefin resin raw material is used for the base material 1 in view of molding cost.
そして、表皮材２は塩化ビニル材よりなるソリッド層３
と、その発泡層４および不織布よりなるバッキング材８
を順に積層したものが使用される。The skin material 2 is a solid layer 3 made of vinyl chloride material.
, the foam layer 4 and a backing material 8 made of nonwoven fabric.
A stack of layers is used.
このように、バッキング材８が必要となる理由は、基材
１への貼り付けの場合、異種材料間では良好な接着性が
期待できないからである。The reason why the backing material 8 is necessary in this manner is that good adhesion cannot be expected between different materials when pasting on the base material 1.
このバッキング材８を基材１に向かい合わせた状態で型
開じしてブロー成形を行ない、冷却固化後、再び型開き
することにより、表皮材２の貼り付けられた成形品Ｓを
得ていた。The mold was opened with this backing material 8 facing the base material 1 and blow molding was performed, and after cooling and solidifying, the mold was opened again to obtain a molded product S to which the skin material 2 was attached. .
（発明が解決しようとする問題点）
上記のようにして成形品を得る場合には、次のような問
題点がある。(Problems to be Solved by the Invention) When obtaining a molded article as described above, there are the following problems.
０表皮材２の貼り付けのために、バッキング材８が特に
必要となる。したがって、表皮材２がコスト高となり、
成形品Ｓ全体の製造コストが高くなる。A backing material 8 is particularly required for pasting the skin material 2. Therefore, the cost of the skin material 2 is high,
The manufacturing cost of the entire molded product S increases.
■バッキング材８の展開能力が乏しく、成形品Ｓの形状
自由度が制約される。(2) The expansion ability of the backing material 8 is poor, and the degree of freedom in the shape of the molded product S is restricted.
■上記した■、■の点はいずれもバッキング材８の持っ
ている欠点であるため、これを除去するためには、バッ
キング材８を廃止できればよい。このためには、表皮材
２を基材１と同様の材質、すなわちオレフィン系樹脂材
料にて製作することが考えられる。しかし、オレフィン
系樹脂自体も展開能力が乏しいことから、やはり形状自
由度に制約を受ける結果となる。(2) The above-mentioned points (2) and (2) are both drawbacks of the backing material 8, so in order to eliminate them, it is sufficient to abolish the backing material 8. For this purpose, it is conceivable to manufacture the skin material 2 from the same material as the base material 1, that is, from an olefin resin material. However, since the olefin resin itself has poor expansion ability, the degree of freedom of shape is still limited.
そこで、本発明は表皮材と基材との接着性を確保しなが
らバッキング材を廃止し、製造コストの低減と成形品の
形状自由度の向上を図らんとしたのである。Therefore, the present invention aims to reduce the manufacturing cost and improve the degree of freedom in the shape of the molded product by eliminating the backing material while ensuring the adhesion between the skin material and the base material.

側に食込む接続の足とすることとしたのである。(Means for Solving the Problems) In order to achieve the above-mentioned technical problem, the present invention provides a method for pasting a skin material on the surface of a synthetic resin base material, in which the skin material is pasted on the surface of a synthetic resin base material prior to molding. The side to which it is attached is brushed, and it is fixed to the mold so that it faces inside the mold. After molding, the parison, which serves as the base material, is extruded between the molds and blow molded. In this case, the nap is used as a connection foot that bites into the base material side.

す。(Operation) Prior to blow molding, the outer skin material is brushed to make the back side stand up. By doing so, these naps will dig into the base material after blow molding and will serve as the connection legs. In addition, part of the nap is molded in a bent state. This kind of nap plays a role of preventing the skin material from being pulled out in the direction of peeling.
（実施例）
以下、本発明を具体化した実施例を図面にしたがって詳
細に説明する。(Example) Hereinafter, an example embodying the present invention will be described in detail with reference to the drawings.

４側を接着面として接着されている。FIG. 1 shows its cross-sectional structure. The base material 1 is made of an olefin resin material (for example, polypropylene), and the skin material 2 is made of a solid B3 made of vinyl chloride material and a foam layer 4 of vinyl chloride laminated thereon. There is. The base material 1 is adhered to the skin material 2 with the foam layer 4 side as the adhesive surface.
次に、成形品Ｓの製造過程について詳細に説明する。Next, the manufacturing process of the molded product S will be explained in detail.
表皮材２は基材１への貼り付けに先立ち、発泡層４の表
面（接着面）に対する処理工程を経る。Prior to being attached to the base material 1, the skin material 2 undergoes a treatment process on the surface (adhesive surface) of the foam layer 4.

。After being pretreated in this manner, the material is moved to a molding process. In the molding process, blow molding is performed in the same manner as in the conventional method. That is, of the two molds 5.6 in the open state, the skin material 2 is placed in advance on one side of the mold 5. In this case, the foam layer 4 side is made to face the base material 1. The parison (base material 1) is placed between both molds 5 and 6.
extrude. Then, by closing the mold and blowing air into the parison, the parison is molded into a predetermined shape following the mold surface. At this time, as the parison expands and deforms, the skin material 2 is pressed against the mold surface and adhered to the surface of the base material 1, so after opening the mold, the molded product S with the skin material 2 attached is taken out. Ru.
ところで、基材１と表皮材２との接着面について考察す
ると、その接着状況は次のようである。By the way, when considering the adhesion surface between the base material 1 and the skin material 2, the adhesion situation is as follows.
第２図はその状況を拡大して示すものである。Figure 2 shows the situation enlarged.

止する。According to the figure, the naps 7 of the raised layer 4 dig into the resin on the base material 1 side and become "connecting legs." Therefore, peeling of the skin material 2 is prevented by increasing the contact area. In addition, some of the naps 7 are molded in a bent state, and in these cases, undercuts (
It plays the role of a pull-out prevention function) and further prevents peeling of the skin material 2.

よい。The present invention is widely applicable in the field of adhesion between resin molded products and the skin material 2, and various modifications can be made to the materials of the skin material 2 and the base material 1. Also,
In this example, the foamed layer 4 was subjected to the napping treatment, but the solid layer 3 may be subjected to the same treatment if the foamed layer 4 does not have this.

As the skin material can be selected from a different material from the sealing material,
For example, it is possible to use a material such as vinyl chloride, which has a high expansion ability, so that the degree of freedom in the shape of the molded product can be increased.
