[First Embodiment]
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the metal-like molded sheet 10 of the present embodiment includes a thermoplastic resin layer 11, an adhesive layer 12, a metal layer 13, a transparent thermoplastic resin layer 14, a primer layer 18, The blue pigment ink layer 15, the transparent weather-resistant ink layer 16, the release layer 22, and the masking film 23 are laminated in order.

  The thermoplastic resin layer 11 is made of, for example, an ABS (acrylonitrile-butadiene-styrene resin) film. The thickness of this thermoplastic resin layer 11 is 50-1500 micrometers, for example. An adhesive layer 12 is formed on one surface of the thermoplastic resin layer 11 by applying a urethane or acrylic adhesive to a thickness of, for example, 1 to 20 μm.

  In addition to the ABS, the thermoplastic resin layer 11 may be appropriately changed to a thermoplastic resin such as polyvinyl chloride, polyolefin, polystyrene, polyacryl, polyurethane, polyamide, or polycarbonate.

  The transparent thermoplastic resin layer 14 is made of, for example, a film made of PET (polyethylene terephthalate), and has a thickness of, for example, 25 to 300 μm. Moreover, for example, indium is vapor-deposited so as to have a thickness of 5 to 300 nm on one surface of the front and back surfaces of the transparent thermoplastic resin layer 14, and the metal layer 13 is formed. The layer 13 constitutes a metal vapor deposition film 21. Then, the metal layer 13 side of the metal vapor-deposited film 21 is brought into close contact with the above-described adhesive layer 12, thereby forming a so-called laminate structure in which the metal layer 13 is sandwiched between a pair of thermoplastic resin layers 11 and 14. . Further, a primer layer 18 is formed on the surface of the transparent thermoplastic resin layer 14 opposite to the metal layer 13 by applying a primer for increasing the adhesion strength of the paint.

  The blue pigment ink layer 15 is obtained by screen-printing a commonly used urethane-based or acrylic-based ink containing an industrial blue pigment on the surface of the transparent thermoplastic resin layer 14 provided with the primer layer 18. It is formed with. The weather resistant ink layer 16 is formed by screen-printing a commonly used urethane or acrylic weather resistant ink on the blue pigment ink layer 15.

Here, each thickness of the blue pigment ink layer 15 and the weather-resistant ink layer 16 is 5 to 8 μm. Therefore, the total thickness of the blue pigment ink layer 15 and the weather-resistant ink layer 16 is 10 μm. It is ˜16 μm. Each thickness of the blue pigment ink layer 15 and the weather-resistant ink layer 16 can be adjusted by the number of meshes of the screen used for screen printing. Specifically, by using a screen of 150 to 350 mesh, the blue pigment ink layer 15 and the weather resistant ink layer 16 having a thickness of 5 to 8 μm can be formed by one screen printing.
Note that it is preferable to perform screen printing using a 150 to 350 mesh screen depending on the target thickness. Further, the thickness of the blue pigment ink layer 15 and the weather-resistant ink layer 16 may be adjusted by performing screen printing a plurality of times.

  The masking film 23 is formed, for example, by forming an acrylic resin into a film shape having a thickness of 25 to 300 μm. In addition, one surface of the masking film 23 is subjected to, for example, an etching process, and the release layer 22 is formed by applying an acrylic pressure-sensitive adhesive thereto. The release layer 22 is in close contact with the weather-resistant ink layer 16. Thereby, the masking film 23 can be peeled from the weather-resistant ink layer 16 together with the peeling layer 22.

The plurality of locking claws 53 project from the lower end of the peripheral wall 52, and these locking claws 53 are inserted into a hole formed at the center of a wheel cap (not shown) and fixed.

  On the surface 50 </ b> A of the wheel decorative component 50, a ring portion 54 protrudes upward from its peripheral edge. Further, an emblem portion 55 shaped like a letter “P” (see FIG. 2) is raised upward in the center of the surface 50A. The wheel decorative component 50 is made of a thermoplastic resin (for example, ABS, modified PPE, PC, PC + ABS, PP, PA, etc.) as a whole, and is a decoration using the metal-molded sheet 10 only on the emblem portion 55. The surface of the surface 50A excluding the emblem portion 55 is coated with a predetermined color.

The wheel decorative component 50 is manufactured through a manufacturing process described below.
In the metal-forming sheet heating step according to the present invention, the metal-forming sheet 10 is gripped by a clamp (not shown), and both surfaces of the metal-forming sheet 10 are heated and softened by a heater (not shown).

  Next, as a forming step according to the present invention, a three-dimensional shape corresponding to the uneven shape on the surface of the wheel decorative component 50 is formed. For this reason, the metallic tone forming sheet 10 is laid on the upper surface of the vacuum mold 60 shown in FIG.

When both pressing dies 81 and 86 are closed, the flat portion 10A and the dome of the metallic tone forming sheet 10 are formed by the edge portion 87 of the opening edge of the punching recess 89 and the edge portion 88 of the step portion 84. The boundary part with the part 10B is cut. In this way, a plurality of dome portions 10B are punched out from the metal-molded sheet 10, and these punched out dome portions 10B become decorative structures 10K.

  Next, as an insert molding step according to the present invention, the wheel decorative component 50 is insert-molded using the metal-tone molded sheet 10 trimmed as described above (that is, the decorative structure 10K). For this purpose, the decorative structure 10K is inserted between the pair of injection molds 65 and 66 shown in FIG. Specifically, a molding recess 63 corresponding to the surface shape of the circular base 51 (see FIG. 3) in the wheel decorative component 50 is formed in one injection mold 65, and the back of the molding recess 63 is formed. A decorative body holding recess 64 for holding the decorative structure 10K is provided at the center of the part. Further, the other injection mold 66 is provided with a circular protrusion 68 corresponding to the back surface shape of the circular base 51. Further, a pair of slide molds 71 and 72 that are opened and closed in the left-right direction in FIG. When the slide molds 71 and 72 are closed, a locking claw molding space 73 is formed between the slide molds 71 and 72 and the side surface 68C of the circular protrusion 68.

  To perform insert molding, the metal-like molded sheet 10 is fitted and fixed in the decorative body holding recess 64 of one injection mold 65, and the injection molds 65 and 66 and the slide molds 71 and 72 are closed. The molten resin is filled from the runner portion 75 into a molding space formed between the injection molds 65 and 66 and the slide molds 71 and 72. Then, after the injection molds 65 and 66 and the slide molds 71 and 72 are cooled and the molten resin is solidified, the injection molds 65 and 66 and the slide molds 71 and 72 are opened. As a result, as shown in FIG. 9, only the emblem portion 55 that is a part of the wheel decorative component 50 is covered with the metallic tone forming sheet 10 (decorative structure 10 </ b> K).

  Next, as a painting process according to the present invention, as shown in FIG. 10, a paint 59 is attached to the surface 50 </ b> A of the wheel decorative component 50 that has been insert-molded. Specifically, a plurality of wheel decoration components 50 are held on a holding plate (not shown) provided with a plurality of holes into which the latching claws 53 of the wheel decoration components 50 can be loosely fitted, and the plurality of wheels. The coating material 59 is sprayed toward the entire decorative part 50. Thereby, the whole surface 50A of the circular base 51 of the wheel decorative component 50 can be painted. At this time, the coating material 59 also adheres to the metallic tone forming sheet 10 exposed on the surface 50A of the wheel decorative component 50.
