  Hereinafter, an example of an embodiment is explained about a manufacturing method of a decoration article of the present invention.

<First embodiment>
In the method for producing a decorative product according to the present invention, a decorative sheet in which a plurality of holes are formed is arranged on one or both molding surfaces of a pair of molds, the molds are closed, and the molds are melted in the mold cavities. The molten resin is integrally formed with the decorative sheet so that the seams formed by injecting the resin and blocking the holes of the decorative sheet are aligned on the decorative surface side, and the mold is opened and the mold is opened. A decorative product in which a plurality of stitch-like portions exposed on the surface of the decorative sheet is formed is taken out.

  First, the decorative sheet 2 in which the plurality of holes 5 are formed is disposed on the molding surface of the movable mold 30 of the mold 3 (see FIG. 1). The decorative sheet 2 may be a laminate obtained by laminating a decorative layer 21 including a protective layer, a design layer, an adhesive layer and the like on the base sheet 20. As the decorative sheet 2, a sheet in which a plurality of holes 5 penetrating both the base sheet 20 and the decorative layer 21 is formed is used.

  The material of the base sheet 20 is not particularly limited, and examples thereof include a polypropylene resin, a polyethylene resin, a polyamide resin, an acrylic resin, an olefin resin, a polyester resin, a vinyl resin, a polycarbonate resin, and an ABS resin. A thermoplastic resin and these laminated products can be mentioned. The thickness of the base sheet 20 can be 20 μm to 600 μm.

  As a method for forming the protective layer, the design layer, and the adhesive layer, a normal printing method such as a gravure printing method, a screen printing method, an offset printing method, or a coating method such as a gravure coating method, a roll coating method, or a die coating method is used. Good.

  In the case where the base sheet 20 is not peeled from the decorative article, the protective layer, the design layer, and the adhesive layer may be formed separately on the front and back of the base sheet 20. For example, only the protective layer may be formed on one side of the base sheet using an ionizing radiation curable resin, and the design layer and the adhesive layer may be formed on the other side of the base sheet. If it does in this way, since the protective layer whose hardness is higher than a base sheet will be the surface of a decorative article, abrasion, damage, etc. of a decorative article can be prevented more effectively. In addition, a soft tactile layer similar to the epidermis can be formed on the protective layer, and fingerprint resistance and antireflection can be imparted.

  In addition, the drying temperature at the time of forming each said layer can be 50 degreeC-200 degreeC, for example.

  The decorative sheet 2 is placed on the molding surface of the movable mold 30 (see FIG. 1). A suction hole may be provided on the molding surface of the movable mold 30 (not shown). If it does in this way, the air between the movable mold | type 30 and the decorating sheet 2 can be attracted | sucked from a suction hole, and the decorating sheet 2 can be closely_contact | adhered to the molding surface of the movable mold | type 30. The decorative sheet 2 is supplied as a single sheet. In addition, the decorating sheet 2 can also be supplied in a metal mold | die using the apparatus which sends the decorating sheet 2 to a molding surface by elongate, for example. The contents described above can also be applied when the decorative sheet 2 is arranged on the molding surface of the fixed mold 31. The suction hole may be formed in a slit shape on the outer periphery of the molding surface so that no trace remains on the decorative sheet 2.

  The decorative sheet 2 may be preliminarily shaped outside the mold and then placed in the mold, or may be arranged by heating and shaping the decorative sheet 2 after being supplied into the mold. Good.

  Moreover, when supplying the decorating sheet 2 to the molding surfaces of both the movable mold 30 and the fixed mold 31 in a long length, the direction of feeding the decorating sheets may be shifted by 90 degrees. That is, the decorative sheet on the movable mold 30 side is sent from the top to the bottom of FIG. 1, and the decorative sheet on the fixed mold 31 side is sent from the back of FIG. 1 to the front (or the front to the back).

  Next, the movable mold 30 and the fixed mold 31 are closed (see FIG. 2). At this time, the cavity 4 is formed between the movable mold 30 and the fixed mold 31.

  Next, molten resin is injected into the cavity 4 (see FIG. 3). Examples of the resin include general-purpose resins such as polystyrene resin, polyolefin resin, ABS resin, AS resin, and AN resin. Also, general engineering resins such as polyphenylene oxide / polystyrene resins, polycarbonate resins, polyacetal resins, acrylic resins, polycarbonate-modified polyphenylene ether resins, polybutylene terephthalate resins, ultrahigh molecular weight polyethylene resins, polysulfone resins, polyphenylene sulfide Super engineering resins such as resins, polyphenylene oxide resins, polyarylate resins, polyetherimide resins, polyimide resins, liquid crystal polyester resins, and polyallyl heat-resistant resins can also be used. Furthermore, composite resins to which reinforcing materials such as glass fibers and inorganic fillers are added can also be used.

  The injected molten resin passes through the plurality of holes 5 formed in the decorative sheet 2 and reaches the molding surface of the movable mold 30. That is, the molten resin closes the plurality of holes 5 and is integrally formed with the decorating sheet 2 so that the plurality of stitch portions 11 are arranged on the decorating layer 21 side (see FIGS. 3 and 6).

  Next, the mold is opened (see FIG. 4). On the fixed mold 31, the decorative product 1 in which the molten resin is integrally formed with the decorative sheet 2 remains. A plurality of seam-like portions 11 formed by the plurality of holes 5 of the decorative sheet 2 are arranged on the decorative surface side of the decorative article 1 (see FIG. 6).

  Finally, the decorative article 1 is taken out from the mold (see FIG. 5). In this embodiment, the base sheet 20 of the decorative sheet 2 does not peel from the decorative layer 21. Therefore, the base sheet 20 becomes the outermost surface of the decorative article 1. Moreover, since the some stitch-shaped part 11 does not jump out from the surface of the decorating sheet 2 as shown in figure, the surface of the decorating goods 1 becomes smooth. In addition, in 2nd embodiment etc. which are mentioned later, when the base sheet 20 is peeled from the decorating layer 21, the several stitch-like part 11 protruded from the decorating layer 21 by the thickness of the base sheet 20. The ornament 1 can be obtained.

  Moreover, as a modification of the method for manufacturing a decorative product according to the present invention, the concave portion 30a is formed at a position where the plurality of holes 5 formed in the decorative sheet 2 on the molding surface on which the decorative sheet 2 is arranged. (See FIGS. 7 and 8). Furthermore, the molten resin injected into the cavity 4 is a thermoplastic elastomer.

  The decorative sheet 2 is the same as that in the above embodiment, and is arranged on the molding surface of the movable mold 30. At this time, the recessed part 30a is formed in the location in which the some hole 5 formed in the decorating sheet 2 is located in the molding surface where the decorating sheet 2 is arrange | positioned. Next, mold clamping is performed, and a thermoplastic elastomer resin is injected into the cavity 4. In the aspect of FIG. 7, since the recessed part 30a is formed in the shaping | molding surface of the movable mold | type 30, from the surface of the decoration 1 obtained, the some stitch-like part 11 protrudes by the depth of the recessed part 30a. . Since the stitched portion 11 is formed by molding a flexible thermoplastic elastomer, the stitched portion 1 has a softer tactile feel than the conventional decorated product in which the stitched portion is formed of a thread. Can be obtained. In the aspect of FIG. 8, it is possible to obtain the decorative product 1 in which the top portion of the stitch portion 11 is formed at the same position as or lower than the surface of the decorative product 1. In this way, it is possible to form a seam-like portion having a shape in which the seam bites into the skin when the skin is tightly stitched. That is, it is possible to form a seam-like portion that is closer to the seam formed by the thread.

  Moreover, if the thermoplastic elastomer which has translucency is used, the several stitch-shaped part 11 will be light-emitted by arrange | positioning the electronic component etc. which contain a light source on the opposite side to the decorating surface side of the decorating goods 1. FIG. Can do. For example, if an electronic component including a plurality of LEDs is combined with the decorative article 1 and used as an audio panel, the audio user can arbitrarily change the color of the stitch-like portion depending on the mood at that time. Moreover, if the electronic component containing several LED and a temperature sensor is combined with the decorating goods 1, and it uses as an interior member of a motor vehicle, the color of a stitch-like part can be changed according to the change of the temperature in a vehicle. When using the thermoplastic elastomer which has translucency, it is preferable that the decorating sheet 2 is colored. The colored base sheet 20 may be used, or the decorative layer 21 may be formed of a colored resin. If it does in this way, it can control that the light from a light source leaks from decoration 1.

  As a modification of the decorative sheet 2 used in the present embodiment, different symbols are formed in two or more regions divided by a plurality of holes 5 (see FIG. 9). In FIG. 9A, a symbol 21b is formed in a substantially rectangular region surrounded by the plurality of holes 5, and a symbol 21c is formed outside the region. In this aspect, it is possible to obtain a decorative sheet 2 in which different symbols 21b and 21c are stitched together. In addition, the area | region of the pattern 21b may be larger than the area | region formed by the several hole 5, and may be small. In this way, since a plurality of symbols can be combined, various expressions are possible.

  Further, as a modification of the mold used in the present embodiment, different concave and convex shapes are formed on the molding surface of the movable mold 30 on the boundary where the plurality of holes 5 formed in the decorative sheet 2 are located. (See FIGS. 9 and 10). Concave portions 30a are formed at locations where the plurality of holes 5 formed in the decorative sheet 2 on the molding surface are located. An uneven shape 30b is formed in the region formed by the recess 30a, and an uneven shape 30c is formed outside the region (see FIGS. 10A, 10B, and 10C). The uneven shape 30b and the uneven shape 30c are different from each other. In the present specification, a smooth surface without unevenness is also included in the uneven shape. When, for example, the decorative sheet 2 shown in FIG. 9A is arranged on the molding surface of the movable mold 30 shown in FIG. 10A, a plurality of holes 5 formed in the decorative sheet 2 are formed into the movable mold 30. Located in the recess 30a formed on the surface. At this time, the pattern 21b is arranged on the molding surface on which the concavo-convex shape 30b is formed, and the design 21c is arranged on the molding surface on which the concavo-convex shape 30c is formed. For example, when the pattern 21b is leather-like and the concavo-convex shape 30b is a textured shape, and the pattern 21c is metallic and the concavo-convex shape 30c is a smooth surface, the leather-like member and the metal-like member are stitched together. An unexpected decorative item 1 can be obtained. As described above, by synchronizing the uneven shape of the molding surface with the design of the decorative sheet, a decorative product with higher texture can be obtained.

  Note that the molding surface on which the concavo-convex shape 30b is formed and the molding surface on which the concavo-convex shape 30c are formed do not necessarily have to be formed in the same plane. For example, referring to FIG. 10B, the molding surface on which the concavo-convex shape 30b is formed may be formed deeper overall than the molding surface on which the concavo-convex shape 30c is formed. If it does in this way, the molding surface in which the uneven | corrugated shape 30b was formed will become a convex shape, and a decorative article with a three-dimensional effect can be obtained.

  In addition, the some hole 5 formed in the decorating sheet 2 does not necessarily need to be cyclic | annular. If such a decorating sheet 2 is used, for example, a decorating product 1 as shown in FIG. 11 can be obtained. The decorative article 1 in FIG. 11A has symbols 21b and 21c in regions divided by one linear stitch portion 11, respectively. The decorative article 1 in FIG. 11B has symbols 21b and 21c in three regions divided by two oblique seam-like portions 11, respectively. The decorative article 1 in FIG. 11 (c) has symbols 21b, 21c, 21d, and 21e in four regions divided by straight intersecting stitch portions 11, respectively.

  In the present embodiment, the decorative sheet 2 having a plurality of holes 5 penetrating both the base sheet 20 and the decorative layer 21 is arranged on the molding surface of the movable mold 30, and then the stitch-like portion 11 is formed by molten resin. To do. Therefore, since the two-color molding method as in the conventional manufacturing method is not used, the stitch-like portion 11 is not easily deformed in the manufacturing method of the present embodiment.

<Second embodiment>
Next, a second embodiment of the present invention will be described. The method for producing a decorative product of the present invention is a method of arranging a molded product formed of a decorative sheet and a molding resin and having a plurality of holes formed on one or both molding surfaces of a pair of molds, and closing the mold. The molten resin is injected into the mold cavity, and the molten resin is integrally molded with the molded product so that the seams formed by blocking the holes in the molded product are lined up on the decorative surface. The mold is opened, and a decorative product in which a plurality of stitch-like portions exposed on the surface of the molded product is formed is taken out.

  First, the molded product 6 made of the decorative sheet 2A and the molded resin 10A and having a plurality of holes 5A is arranged on the molding surface of the movable mold 30A (see FIG. 12). The same decorative sheet 2A as in the first embodiment can be used. As the molded product 6, a product obtained by integrally molding the decorative sheet 2A and the molded resin 10A is used. In the molded product 6, a plurality of holes 5A penetrating both the decorative sheet 2A and the molded resin 10A are formed. The molded product 6 can be fixed to the molding surface of the movable mold 30A through a suction hole provided on the molding surface of the movable mold 30A or using a fixing jig or the like. In addition, after shape | molding the molded product 6, you may use the molded product 6 which peeled the base sheet of the decorating sheet 2A.

  Next, the movable mold 30A and the fixed mold 31A are closed (see FIG. 13). At this time, a cavity 4A is formed between the movable mold 30A and the fixed mold 31A.

  Next, molten resin is injected into the cavity 4A (see FIG. 14). As the resin, the same resin as in the first embodiment can be used. The injected molten resin passes through the plurality of holes 5A formed in the molded product 6 and reaches the molding surface of the movable mold 30A. That is, the molten resin is integrally formed with the molded product 6 so as to close the plurality of holes 5A and to arrange the plurality of stitch-like portions 11A on the decorative sheet 2A side (see FIGS. 14 and 17).

  In the present embodiment, it is preferable to form a recess 30a ′ on the molding surface of the movable mold 30A at a position where the plurality of holes 5 formed in the molded product 6 are located (see FIGS. 19A and 19B). ). In the aspect of Fig.19 (a), the decoration 1A in which the top part of the stitch-like part 11A was formed in the same position as the surface of the decoration sheet 2A or lower than that can be obtained. In this way, it is possible to form a seam-like portion having a shape in which the seam bites into the epidermis when the epidermis piece is sewn tightly. That is, it is possible to form a seam-like portion that is closer to the seam formed by the thread. In FIG. 19A, it can also be said that there is a portion protruding from the molding surface of the movable mold 30A at a position corresponding to the hole 5A, and a recess 30a ′ is formed on the end surface. Therefore, it is possible to arrange the molded product 6 on the molding surface of the movable mold 30A by using the protruding portion including the recess 30a ′ as the positioning means for the hole 5A. In the embodiment of FIG. 19 (b), it is possible to obtain a decorative product 1A in which the seam-like portion protrudes by the depth of the recess 30a ′. In any embodiment, it is possible to obtain a high-quality decorative product in which a stitch is formed with a thread on the skin piece.

  Next, the mold is opened (see FIG. 15). In the fixed mold 31A, the decorative product 1A in which the molded resin 10B is integrally formed with the molded product 6 remains. On the decorative surface side, a plurality of seam-like portions 11A formed by a plurality of holes 5A are arranged (see FIG. 17).

  Finally, the decorative article 1A is taken out from the mold (see FIG. 16).

  As a modification of the method for manufacturing a decorative product of the present invention, the molten resin injected into the cavity 4A is a thermoplastic elastomer. In particular, when the decorative product is used in a vehicle, a polyester-based or polyamide-based elastomer having a heat resistant use temperature of 100 ° C. or higher is effective. In the conventional manufacturing method, a plurality of seam-shaped portions are formed with a primary resin, and then formed with a secondary resin. Therefore, when the thermoplastic elastomer is used as the primary resin in the conventional manufacturing method, the thermoplastic elastomer is deformed by the resin pressure or the resin heat in the secondary molding. On the other hand, in the manufacturing method of the present invention, after forming a plurality of through holes in the molded article 6, a thermoplastic elastomer is used as a secondary resin to form a plurality of stitched portions 11A. Accordingly, the plurality of seam-like portions 11A formed of the thermoplastic elastomer are not easily deformed.

  Moreover, when using the thermoplastic elastomer which has translucency, it is preferable that at least one of the decorating sheet 2A or the molding resin 10A is colored. When the decorative sheet 2A includes a base sheet, a colored base sheet may be used. When 2 A of decorating sheets do not contain a base sheet, you may form a decorating layer with colored resin. Alternatively, a colored molding resin 10A may be used. Colored decorative sheet 2A and colored molding resin 10A may be used. If it does in this way, it can control that the light from a light source leaks from decoration 1A.

  In the second embodiment, the molding resin 10B is formed in a casing shape on the entire back surface of the molding resin 10A. The shape of the molded resin 10B is not limited to this, and the molded resin 10B can be formed on a part of the back side of the molded product 6 as shown in FIG.

  In the molding of the molded resin 10B, the deformation of the molded product 6 occurring at the time of injection can be more effectively suppressed by combining the compression molding with the low pressure molding.

  As described above, the decorative product of the present invention can be obtained.
