。<Means for Solving the Problems> The present invention provides a skin material fixing device which is movably attached to the female mold or male mold of a molding device consisting of a female mold and a male mold, and has an opening through which the convex portion of the male mold passes. After the peripheral edge of the skin material is held between the fixed frame and the female mold by the frame, a core material molten resin is supplied between the skin material and the female mold or the male mold, and the female mold and the male mold are In the production of a multilayer molded product consisting of a skin material and a core resin that are molded together, the sliding resistance of the fixed frame and the female mold against the periphery of the skin material can be adjusted depending on the location of the fixed frame and/or the shaping of the skin material. The present invention relates to a method for producing a multilayer molded product, which is characterized by arbitrarily controlling the time during the process.

のためには表皮材の周縁を適切な力で挾持して表皮材に
対するすべり抵抗を制御することが効果的である。In order to realize a skin material lamination method that maintains the nice texture of the skin material even in the production of complex-shaped molded products and does not cause wrinkles or tears, it is necessary to
It is necessary to keep the stretching of the skin material to a minimum and to prevent excess skin material from slipping into the cavity. For this purpose, it is effective to control the sliding resistance against the skin material by clamping the periphery of the skin material with an appropriate force.

時間円において、時間により表皮材に対するすべり抵抗
を変化させる仁とにより表皮の風合のすぐれた成形品を
得ることができる。When the shape of the molded product is relatively simple, the slip resistance of the skin material is almost uniform around the entire periphery of the skin material, and there are no wrinkles or tears, and the texture of the skin material is maintained even if no control is performed during the shaping process. However, as the shape of the molded product becomes more complex, the slip resistance against the skin material will vary depending on the location, and if necessary, the time required for the shaping process will be changed. By changing the sliding resistance against the skin material, it is possible to obtain a molded product with an excellent skin texture.
雌型と表皮材固定枠により挾持される表皮材周縁の場所
によるすべり抵抗の調整は次のような方法で実施するこ
とができる。The sliding resistance can be adjusted by the location of the peripheral edge of the skin material held between the female mold and the skin material fixing frame by the following method.
単一の固定枠を用いて、場所によってすべり抵抗を胴筒

接面側の必要個所にすべり抵抗の閏なる面材を貼合わせ
る方法を用いることができる。A method of increasing slip resistance depending on the location using a single fixed frame is to attach a surface material with increased slip resistance to the necessary locations on the skin material fixing frame or the female skin material contact surface side. can be used.

ャビティ内への滑り込みを抑制することが好ましい。ま
た、絞りの深い部分には絞りの浅い部分よりすべり抵抗
を小さくすることが好ましい。For example, when molding a box-shaped molded product with skin material laminated on the outside, the square parts of the box are areas where the skin material is left over, so the slip resistance is made greater than other parts. It is preferable to suppress sliding into the cavity. Further, it is preferable that the slip resistance be lower in the deep part of the aperture than in the shallow part.
他方、表皮材固定枠を分割して、各分割固定枠の表皮材
挾持力を別個に制御することもできる。On the other hand, it is also possible to divide the skin material fixing frame and separately control the skin material clamping force of each divided fixing frame.
各分割固定枠には空気圧または油圧で作動するシリンダ
ーを１つ以上設け、それぞれの空気圧または油圧を各部
の表皮材に対するすべり抵抗に見合りた値に設定するこ
とによって達成せられる。This is achieved by providing each divided fixed frame with one or more cylinders operated by pneumatic pressure or hydraulic pressure, and setting the respective pneumatic pressure or hydraulic pressure to a value commensurate with the sliding resistance of each part to the skin material.
また、前者の面材を貼合または載置する方法及び後者の
固定枠を分割し、空気圧または油圧を場所によって変更
することを併用することもできる。Furthermore, the former method of bonding or placing the face materials and the latter method of dividing the fixing frame and changing the air pressure or oil pressure depending on the location can also be used together.

る。■ When the lifting mechanism is further operated to lower the female mold 8 and the skin material fixing frame 4, the molten resin 11 flows and the skin material lO
is pressed against the female mold 8 side, and as a result, the peripheral edge 12 of the skin material 10 is sliding between the skin material fixing frame 4 and the female mold 8, and the skin material 10 is being stretched into the recess of the female mold 8. (Figure 4). At this time, the ratio of sliding and elongation at each time during the shaping process of each part of the skin material is
It is determined by the sliding resistance of the skin material between the mold 8 and the female mold 8. In this embodiment, a face material 6 with high slip resistance is attached to a part of the upper surface of the skin material fixing frame 4. This changes the sliding resistance to the skin material depending on the location, and also allows the expansion and contraction device 5
．． By controlling the oil pressure at 6' in multiple stages depending on the position of the female die 8, the sliding resistance against the skin material can be changed depending on the time during the forming process of the skin material. The slip resistance against the skin material is increased and controlled at certain points and timings.

ずしも前述のタイミングに限定されるものでない。(2) As the female mold 8 continues to descend further, both molds 2.8 are completely clamped, the skin material 10 and the synthetic resin 13 are integrated, and the molding is completed. (FIG. 5) In the method of the present invention, the timing of supplying the molten resin 11 is not necessarily limited to the above-mentioned timing.

力の設定が特に重要である。In the method of the present invention, as shown in FIGS. 8 to 5, the peripheral edge (2) of the skin material αO gradually moves inward of the female mold (3) as molding progresses, so that the slip resistance against the skin material is exerted. The settings are particularly important.
すなわち、表皮材ＱＯは雌型（３）の降下に伴い雌型（
３）の形状にほぼ沿った形状に変形しようとする。In other words, the skin material QO changes to the female type (3) as the female type (3) descends.
It attempts to deform into a shape that roughly follows the shape of 3).

。Here, if the slip resistance against the skin material due to the formation of the skin material fixing frame (4) is too small, the skin material αO will cause a large slip between the female die (3) and the skin material fixing frame (4), and the laminate (1
The skin material αQ having an area larger than that required for step 4) is supplied into the female mold (3), causing wrinkles. On the other hand, if the surface constant force is excessive, the skin material OO will not be able to withstand this tension and will be damaged.

化するように設定する。In order to obtain a molded product with a good texture without wrinkles and with minimal elongation of the skin material during the production of complex-shaped products, it is necessary to improve the slip resistance of the skin material and the process of shaping the skin material. It is important to have detailed and precise control by the time within. The slip resistance of the skin material at each time during the skin material shaping process for each part of the skin material is determined by the material properties, that is, the elongation of the skin material lO, or the structural properties of the molded product, such as the shape of the molded product, each vertex, and each side. It is also necessary to set the curvature to the optimum value. Generally, first, the hydraulic pressure of the expansion device is set to a low level so that the whole body has a small sliding resistance, and in this state, the state of wrinkles is confirmed, and the skin material fixing frame corresponding to the part where the wrinkles are generated is Depending on the degree of wrinkles on the surface, a surface material with high slip resistance is attached to adjust the slip resistance of each part. Also, if necessary, the oil pressure of the expansion and contraction device is set to purple depending on the location and time during the skin material shaping process.
