ムを接合させて車両用の内装材を製造していた。Traditionally, armrests, hemrests, back garnishes for seatbacks, door panels, etc. (7) In the case of interior materials for vehicles, a synthetic resin frame that serves as the core material is manufactured in advance, and urethane, etc. are coated on the outside. The cushioning material is bonded using adhesive or the like, or the molded frame is inserted into the foaming mold, and the stock solution of the foaming synthetic resin is injected into the foaming mold, and the cushioning material is synthesized by foaming. The company manufactured interior materials for vehicles by bonding resin frames together.

述する所より明らかとなるであろう。The purpose of the present invention is to provide an economical manufacturing method for interior materials for vehicles, etc., which allows the cushioning material and the synthetic resin frame to be joined without a separate joining process, which significantly improves work efficiency. It will become clear from the detailed description below with reference to the drawings.

形成されている空気吹込口１３より圧縮空気を吹込む。Next, as shown in FIG. 2, a bebe ring 12' made of heated and melted thermoplastic synthetic resin is extruded from the die 11 of an extruder placed at the top of the blow molding machine 1, and then molded as shown in FIG. The molds 2 and 3 are matched, and compressed air is blown into the mold through an air blowing port 13 formed at the tip of the die 11.

合された緩衝材５が得られる。The parison 12' is brought into close contact with the mold 2°3 by compressed air, but the parison 12' is heated in the existing portion of the unfoamed synthetic resin sheet 5' placed in the mold 2. As a result, the unfoamed foamed synthetic resin sheet 5' is heated, foaming progresses, and as the parison 12' is formed into the synthetic resin frame 12 as a core material, the synthetic resin frame 12 is heated. A cushioning material 5 that is integrally joined is obtained.

It will be done.

両等の内装材の製造方法を得る事が出来る。The above is an outline of an embodiment in which the present invention is applied to an armrest. According to this method, an unfoamed synthetic resin sheet is placed in a mold, and a synthetic resin frame is molded. When the heated parison is pressed into the mold, the heat of the parison causes the foamed synthetic resin sheet to expand and form the cushioning material, so the synthetic resin frame and the cushioning material are firmly joined, and the synthetic resin frame is formed. It is possible to significantly improve manufacturing efficiency without requiring a separate bonding process for bonding a cushioning material to the interior of a vehicle, and to obtain an economical method for manufacturing interior materials for vehicles, etc.

す事が出来る。、In addition, although the case where the unfoamed synthetic resin sheet 5' is disposed only on the inside of the mold 2 has been described above, it is also possible to arrange it over the entire inner surface of the molds 2 and 3. Alternatively, if it is applied to products such as Basokuga 12 Sonyu that do not require blow molding, the same method as described above can be achieved by simply molding using a thermoplastic synthetic resin heated and melted without using Parinon 12'. It is possible to obtain an interior material having the structure and effect, and furthermore, if the molds 2 and 3 are formed with grains for graining treatment in advance, the surface of the integrally molded product can be grained at the same time. ,
