We adopted a method consisting of a step of molding, a step of clamping the same mold, a step of forming a base resin layer on the back side of the skin by blow molding or injection molding, and a step of opening the mold and taking out the molded product. By doing so, it is possible to manufacture a skin insert molded product with good appearance of the boundaries between multiple skins without using a member such as a molding that hides the boundaries.

きる。(Function) After connecting the skins by bringing the end surfaces of the plurality of skins into close contact with the fixed plate protruding into the molding recess, the mold is closed and a base resin layer is formed on the back side of the skins by blow molding or injection molding. Since the mold is formed by forming a mold, opening the mold, and molding, it is possible to manufacture a skin insert molded product with a good-looking boundary between multiple skins without waviness at the boundary.

The mold is opened and the molded product is taken out. Therefore, the joint end of the skin is rolled up to the back side, and the joint is hidden by the surface of the skin, and since the joint end is formed after the fixed plate, there is no undulation at the boundary.
（実施例）
以下、本発明をドアトリムボードに具体化した第１実施
例を第１〜３図に従って説明する。(Example) Hereinafter, a first example in which the present invention is embodied in a door trim board will be described with reference to FIGS. 1 to 3.

する。At each bent end of the skins 1 and 2, the skins 1 and 2 are bent.
They are sandwiched and connected by clamps 3 made of extruded polypropylene resin and having a U-shaped cross section and having the same length as the width of 2. Note that the ends of the skins 1 and 2 sandwiched by the clamp 3 and the portion where the ends of the skins 1 and 2 are bent so that they touch or come close to each other are referred to as a joint A.

きるようになっている。6d has a thickness of 0.5 to 0.5 which protrudes into the molding recesses 6a and 6b by the same length and depth as the joint A of the skin 1.2.
Fixed plates 7a and 7b each having a 3 mm long and narrow plate shape are fixed. Note that the fixed plates 7a and 7b are made of a highly rigid material such as metal, for example. The molds 5a, 5b
An air blowing nozzle 8 is movably arranged in the middle of the gap, and around the nozzle 8 are the molds 5a, 5.
An elliptical cylindrical parison 11 made of thermoplastic resin such as polypropylene, polyethylene, ABS resin, etc. can be supplied hanging from a die 10 of an extrusion device 9 installed above b.
次に、製造方法を説明する。Next, the manufacturing method will be explained.

Fold the surface of each end so that they fit together, then
The rain shelters 1a and 2a are clamped together with the fixed plate 7a by the clamp 3, and the cloths la and 2a are locked and connected.
また、金型５ｂの固定板７ｂにも上記と同様にクランプ
３によって布１ｂ、２ｂを係止して接続しておく。Furthermore, the cloths 1b and 2b are secured and connected to the fixing plate 7b of the mold 5b with the clamp 3 in the same manner as described above.
次に、エアー吹き出し用のノズル８を前記両金型５ａ、
５ｂ間に進出させるとともに押出装置９のダイス１０か
ら前記ノズル８を囲むようにパリソン１１を供給する。Next, the air blowing nozzle 8 is attached to both the molds 5a,
5b, and the parison 11 is supplied from the die 10 of the extrusion device 9 so as to surround the nozzle 8.
そして、ノズル８からエアーを放出させておき、パリソ

せる。Then, air is released from the nozzle 8, and the molds 5a and 5b are closed with the nozzle 8 in between, while slightly inflating the parison 11. Therefore, the elliptical cylindrical parison 1
When the mold is closed, the mold 1 is held between the nozzle 8 and both molds 5a and 5b so as to be divided into left and right parts. After the mold is closed,
The parison 11 is inflated by further blowing out air from the nozzle 8, and the cloths 1a, 2a are aligned with the bottom surface of the molding recess 6a of the mold 5a, and the cloths 1b, 2 are
b along the bottom surface of the molding recess 6b of the mold 5b, and bonded to the back surface of the clamp 3a and the back surfaces of the cloths 1a, 2a, and cloths 1b, 2b as base resin layers 4a, 4b.
パリソン１１が基材樹脂ｊｉ４ａ、４ｂとして冷却完了
後、型開きを行い固定板７ａ、７ｂより接合部Ａを引き

取り外せばよい。After the parison 11 is completely cooled as a base resin ji4a, 4b, the mold is opened, the joint A is separated from the fixing plates 7a, 7b, and the door trim board is removed from the molding recesses 6a, 6b.
上記のように形成されたドアトリムボードの作用効果を
述べる。The effects of the door trim board formed as described above will be described.

るので、その接合部Ａはより強固なものとなっている。The surfaces of each end of the cloths 1a, 2a, lb, 2b are placed in contact with fixing plates 7a, 7b, respectively, and are connected by a clamp 3, as well as at the joint A of the cloths 1a, 2a, la, 2b. Since the base resin layer 4 is formed by integrally bonding the base resin to the back surfaces of the fabrics 1a, 2a, lb, and 2b by blow molding, the joint A of the skin 1.2 is fixed to the IJ
A linear boundary with good appearance is formed along i7a, 7b, and the joined ends of each of the skins 1.2 are bent toward the back side, so that the bent parts of the skins 1.2 are not close to each other or are joined together. Therefore, there is no need to weld using a molding or the like to hide the joint A. Furthermore, since the joint A of the skin 1.2 is lined with the base resin layer 4 during blow molding, the joint A is stronger.
更にまた、表皮１．２の裏面と基材樹脂とをブロー成形
により、成形と同時にアンカー効果などによって接合す

This embodiment differs from the first embodiment in that a needle 21 is provided protruding from the tip of a fixing plate 70 as shown in the figure. That is, the needles 20 are provided protruding from the tip of the fixing plate 70 at regular intervals. The end of the epidermis 21 is pierced and locked by the placing needle 20, and then the end of the epidermis 22 is overlaid and pierced from above to be latched, and the epidermis 21. A base resin layer 40 is formed on the back surface of 22, and the mold is released from the mold to produce an insert molded product.
上記のことから、この第２実施例も第１実施例と同様な
