品に関するものである。[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a resin molded product that is used as various interior and exterior parts of automobiles, for example, and has a skin for decoration or heat insulation on its outer surface. It is.

は射出成形によるインモールド成形とがある。(Prior Art) Conventionally, as a method of integrally providing a sheet-like skin on the outer surface of a base material made of synthetic resin, there are skin attachment by vacuum forming or in-mold molding by injection molding.

なるという問題があった。However, applying the skin using vacuum forming requires two steps: forming the base material into a predetermined shape and pasting the skin on the outer surface of the base material, which reduces production efficiency. There was a problem.

その作業が面倒であった。Additionally, in this method, it is necessary to interpose an adhesive between the base material and the skin. For example, if the base material is made of a non-polar resin material such as polypropylene, the bonding strength of the adhesive to the non-polar material may be reduced. There was a problem that the epidermis easily peeled off because the surface was not very high. Moreover, since the base material is pre-formed into a predetermined shape, when adsorbing the epidermis to the base material, air must be extracted from the base material side. It was necessary to process it, and that work was troublesome.

った。In addition, in the case of in-mold molding by injection molding, high pressure (usually 50 kg/cm) and high temperature (usually 160 to 2
Since the base material and the skin are bonded together at a temperature of 40° C., for example, when a raised or flocked fabric is used as the skin, there is a problem in that the hairs come off due to the pressure and heat during bonding. Furthermore, when a porous sheet such as a rough cloth of Comparative Approximately 1 was used as the skin, there was a drawback that the flow of resin during molding appeared as an irregular pattern on the skin after processing.

によって強固に固着されている。FIG. 2 shows an enlarged view of the bonding state between the base material 1 and the skin 2, and shows that the base material 1
The molten resin permeates between the threads 4 constituting the skin 2 and hardens. If a thermoplastic synthetic fiber yarn such as polyester is used as the yarn 4 of the skin 2, the molten synthetic resin of the base material 1 will melt a portion of the yarn 4 and fuse them. Therefore,
Even without interposing an adhesive between the base material 1 and the skin 2, the skin 2 is firmly fixed to the outer surface of the base 1 by mechanical anchoring effect or fusion.

る。First, a pipe-shaped parison 9 that forms the base material 1 is extruded by a die 8 between a pair of molds 6 and 7, and a sheet-like skin 2 is formed between the parison 9 and one of the molds 6.
are placed with a slight margin to accommodate the increase in surface area during blowing. Then, an air blowing nozzle 10 is inserted into the lower end of the parison 9, and as shown in FIG. 4, compressed air is blown from the air blowing nozzle 10 while the image forming molds 6 and 7 are aligned. Then, the parison 9 is expanded in the cage between the drawing molds 6 and 7, and the molten resin of the parison 9 is penetrated between the threads 4 of the skin 2 by the air pressure of the compressed air, and a portion of the resin is injected into the threads 4. is fused with
A skin 2 is integrally fixed to the outer surface of the parison 9. after that,
The resin molded product shown in FIG. 1 can be manufactured by cooling, releasing the drawing mold 6.7, and finishing the joint edges of the molded product.

ムラ等を隨すこともできる。In the resin molded product of this example constructed and manufactured as described above, the outer surface of the base material 1 is covered with the skin 2 made of cloth, so that it is possible to obtain the soft feel and appearance peculiar to cloth. This makes it possible to enhance the decorative effect of the product compared to when molding only from synthetic resin. In addition, scratches that occur on the outer surface of the base material 1 during molding due to the skin 2,
It is also possible to eliminate unevenness.

は、ブロー成形による固着法が非常に有利である。Moreover, according to the manufacturing method, molding of the base material 1 and fixing of the skin 2 can be performed simultaneously in one process by blow molding, unlike the case of bonding using a conventional adhesive. The production efficiency can be improved. Moreover, since the skin 2 is fixed to the base material 1 by the above-mentioned mechanical anchoring effect and fusion, there is no fear that it will peel off or be damaged by external forces during use. In particular, l, which is relatively inexpensive but does not have polar groups,
When the base material 1 is formed of a polyolefin resin such as a polypropylene resin, which is difficult to adhere with an adhesive, a fixing method using blow molding is very advantageous.

それがない。It is composed of a foam layer 14 made of polyester or the like, and a flocked pile 16 adhered to the surface of the foam layer 14 via an adhesive 15. Therefore, this skin 2 is applied to the outer surface of the base material 1.
According to the resin molded article provided with this, the cushioning properties and heat retention/insulation effects of the foam layer 14 can be obtained, and the feel and appearance unique to the flocked pile 16 can be obtained. Further, during blow molding, the molten resin of the base material 1 permeates not only into the cloth 12 but also into the foam layer 14, so that the foam layer 14 further strengthens the adhesion between the base material 1 and the skin 2. Moreover, the air pressure of compressed air during blow molding is usually relatively low at 2 to 3 kg/am, so unlike when the base material 1 and the skin 2 are integrally bonded by injection molding, the foam layer 14 The void is crushed! There is no fear that the hair in the stiff flocked pile 16 will curl.
