型により取り出すことの必要があった。Conventionally, integral foam molding of a skin body and a foam such as polyurethane foam has been known, and one of these known methods is
One is to form the skin material in advance by vacuum forming, slush molding, rotational molding, etc., and on the other hand, to form the core material by press molding or injection molding, and then bond the two together with an adhesive.
Another method is to pre-form a skin of a predetermined size after the urethane foam shrinks using a holding mold that is large enough to take into account molding shrinkage of the urethane foam, and then place this skin in the foaming holding mold. , vacuum is applied from the outer periphery of the holding mold until it reaches the size of the holding mold, it expands elastically, and in this state, the urethane foam raw material is injected while holding the epidermis inside the holding mold.
After completing foaming, the foamed molded product is taken out of the holding mold to obtain a product of a predetermined size. However, in all of these methods, the mold for molding the skin and the mold for foam molding are separate, and it is necessary to take out the skin material once using the mold.

形品の製造方法にある。The present invention focuses on the above-mentioned facts, and uses only a single mold without preforming the skin material and the core, and also forms the mold for the skin material (= eliminating the need for a JT culm). The purpose is to obtain molded products, and its characteristics are that a soft thermoplastic resin sheet, which will become the skin 4, 1, is placed in the lower mold of a split mold (multiple upper molds are combined, and then Place the molded product in a state that allows RIM molding, and add the raw resin to the above.
A method for manufacturing a molded article with a skin body A-1 in which a skin body and a core body are integrated by injecting between the surface of the mold II and a soft thermoplastic sheet and reaction hardening.

After sealing (see Figure 1), the mold (4) is assembled and the thermoplastic resin sheet 1 (1) is pressed and clamped, and the sheet (]) is pressed against the flank surface (3) of the mold. Clamp and fix.

It is injected at high pressure into the interior and instantly mixed to fill the void (5
). In this case, the temperature of the resin liquid is 80℃~1
The temperature is 80°C, and at this temperature, the soft thermoplastic 4F・I resin sheet (]) becomes soft, and due to the injection pressure of the resin liquid, it does not stick tightly to the inner surface of the lower mold (2). At the same time, it is integrated with the core body (6) made of resin liquid.

+”B化がはかれる。In the method of the present invention, the soft thermoplastic resin sheet 1 serving as the skin material is installed on the lower mold, and then the mold is assembled into the lower mold.
RI in the space formed between the sheet and the upper mold at 114 degrees.
In order to inject the resin liquid using the M-molding method, the sheet mentioned above easily adheres to the inner surface of the lower mold due to the temperature of the mold, the temperature of the resin liquid, and the injection pressure of the resin liquid, and the sheet can be easily adhered to the inner surface of the lower mold, and the sheet can be easily adhered to the inner surface of the lower mold due to the temperature of the mold, the temperature of the resin liquid, and the injection pressure of the resin liquid. Adhesively integrate with the core body. As a result, the method of the present invention uses only one mold and there is no need to preform the epidermis, thereby reducing mold costs and simplifying the process.
