The technology is disclosed in Patent Document 1.

Japanese Patent No. 3472403

  Since the base sheet 112 is a resin film, its thermal conductivity is inferior to that of the mold, but it is usually as thin as about 25 to 300 μm. Therefore, when the primary molding resin 131 is injected (see FIG. 6A), heat conducted to the primary decorative layer 113 can be dissipated toward the primary molding cavity mold 102 through the base sheet 112. . As a result, the primary decorative layer 113 can withstand the flow resistance of the primary molded resin 131 without being heated and softened by the primary molded resin 131, and can maintain the position. There will be no problem.

  However, the primary molded resin portion 132, which is similarly inferior in thermal conductivity to the mold, usually has a thickness of 500 μm or more. Therefore, when the secondary molding resin 141 is injected (see FIG. 6C), heat conducted to the primary decoration layer 113 cannot be dissipated toward the core mold 101 through the primary molding resin portion 132. As a result, the primary decorative layer 113 is heated and softened by the secondary molding resin 141 and flows without resisting the flow resistance of the secondary molding resin 141, resulting in the appearance defect of the two-color molded decorative product 143. (See FIG. 7).

  An object of the present invention is to provide a method for producing a two-color molded decorative product so as not to cause the above problem.

  In order to achieve the above object, the present invention has the following features.

The manufacturing method of the two-color molded decorative article of the present invention includes a core mold, a primary mold cavity mold in which a primary decorative sheet in which a primary decorative layer is laminated on a base sheet, and secondary molding. Using a two-color molded decorative mold with a cavity mold for

It is sectional drawing which shows the two-color molded ornament formed by the manufacturing method of the conventional two-color molded ornament.

  Embodiments of the present invention will be described in detail with reference to the drawings.

  First, the two-color molded decorative mold, the primary decorative sheet 11 (and the secondary decorative sheet 21) used in the method for producing a two-color molded decorative product of the present invention, the primary molded resin 31 and the secondary molded. The resin 41 will be described.

  The two-color molding decorative mold includes a core mold 1, a primary molding cavity mold 2, and a secondary molding cavity mold 3 (see FIG. 1). The core mold 1 is used to form the back surface shape of the two-color molded decorative article 43 to be finally formed. In the primary molding cavity mold 2, the primary decorative layer 13 is laminated on the surface of the primary molded resin portion 32 to form the surface shape of the primary molded decorative product 33 that becomes the base of the two-color molded decorative product 43. Used for. The primary molding cavity mold 2 forms the primary molding cavity mold 4 by closing the mold with the core mold 1. In the primary mold cavity mold 2, a primary decorative sheet 11 in which a primary decorative layer 13 is laminated on a base sheet 12 is disposed. The secondary mold cavity mold 3 is used to form the surface shape of the two-color molded decorative product 43 in which the secondary molded resin portion 42 is laminated on the surface of the primary molded decorative product 33. The cavity mold 3 for secondary molding is designed to have a larger outer shape than the cavity mold 2 for primary molding and to form a portion that does not contact the primary molded decorative product 33. This non-contact portion corresponds to the secondary molding cavity 5.

  The primary decorative sheet 11 (secondary decorative sheet 21) has a primary decorative layer 13 (secondary decorative layer 23) laminated on at least the base sheet 12 (base sheet 22), and is peeled off as necessary. Layer 14 (peeling layer 24), adhesive layer 15 (adhesive layer 25), and the like are provided (see FIG. 2).

  As the base sheet 12 (base sheet 22), polyester resin, polypropylene resin, vinyl chloride resin, polyethylene resin, polyethylene terephthalate resin, polycarbonate resin, nylon resin, vinylon resin, acetate resin, polyethylene resin, polyamide resin, Plastic sheets such as polyacrylic resin and polyvinyl chloride resin can be used. The thickness of the base sheet 12 (base sheet 22) may be 10 to 500 μm.

  When the base sheet 12 (base sheet 22) is peeled off, the primary decorating sheet 11 (secondary decorating sheet 21) becomes a transfer sheet. In this case, you may form the peeling layer 14 (peeling layer 24) as needed. The peeling layer 14 (peeling layer 24) is a layer that peels from the base sheet 12 (base sheet 22) and becomes the outermost surface of the transfer object. Examples of the material of the release layer 14 (release layer 24) include acrylic resin, polyester resin, polyvinyl chloride resin, cellulose resin, rubber resin, polyurethane resin, polyvinyl acetate resin, and vinyl chloride. -Copolymers such as vinyl acetate copolymer resin and ethylene-vinyl acetate copolymer resin may be used. As will be described later, when the secondary decorative sheet 21 is used to form a two-color molded decorative product 43 and the release layer 24 that is the outermost surface of the two-color molded decorative product 43 requires hardness, ultraviolet curable A photocurable resin such as a resin, a radiation curable resin such as an electron beam curable resin, a thermosetting resin, or the like may be selected and used. As a method for forming the release layer 14 (release layer 24), there are a coating method such as a gravure coating method, a roll coating method and a comma coating method, a printing method such as a gravure printing method and a screen printing method.

  As a material of the primary decoration layer 13 (secondary decoration layer 23), polyvinyl resin, polyamide resin, polyester resin, acrylic resin, polyurethane resin, polyvinyl acetal resin, polyester urethane resin, cellulose A colored ink containing a resin such as an ester resin or an alkyd resin as a binder and a pigment or dye of an appropriate color as a colorant may be used. As a method for forming the primary decorative layer 13 (secondary decorative layer 23), a normal printing method such as a gravure printing method, a screen printing method, or an offset printing method may be used. As thickness of the decoration layer 4, 1-20 micrometers is preferable. If it exceeds 20 μm, it becomes difficult for the heat conducted to the primary decorative layer 13 to be dissipated toward the core mold 1 through the primary molding resin portion 32 when the secondary molding resin 41 is injected. The primary decorative layer 13 is softened and cannot withstand the flow resistance of the secondary molded resin 41, so that the appearance defect of the two-color molded decorative product 43 may occur. If it is thinner than 1 μm, the concealment necessary for the design cannot be obtained. The primary decorative layer 13 (secondary decorative layer 23) is not limited to colored ink, but may form a metal vapor deposition layer or the like to express a design with metallic luster. Aluminum, chromium, copper, tin, or the like is used as the material for the metal deposition layer. The metal vapor deposition layer may be formed by using a vacuum vapor deposition method, a sputtering method, an ion plating method, or the like.

  Moreover, you may form the contact bonding layer 15 (adhesion layer 25) as needed. The adhesive layer 15 (adhesive layer 25) is a layer for adhering to the primary molding resin part 32 (secondary molding resin part 42). When the material of the primary molding resin part 32 (secondary molding resin part 42) is a polyacrylic resin, it is preferable to use a polyacrylic resin as the material of the primary molding resin part 32 (secondary molding resin part 42). . Also, when the material of the primary molding resin part 32 (secondary molding resin part 42) is polyphenylene oxide / polystyrene resin, polycarbonate resin, styrene copolymer resin, or polystyrene blend resin, it has an affinity for these resins. Polyacrylic resin, polystyrene-based resin, polyamide-based resin, or the like having a certain property may be used as the material for the adhesive layer 15 (adhesive layer 25). As a method for forming the adhesive layer 15 (adhesive layer 25), a coating such as a gravure coating method, a roll coating method, or a comma coating method, a gravure printing, a screen printing method, or the like may be used. The dry film thickness of the adhesive layer 15 (adhesive layer 25) is generally 1 to 5 μm.

  The primary molding resin 31 is obtained by mixing aluminum, tungsten, zinc, silver, gold, platinum, iron, copper, carbon, or the like as a high thermal conductivity material into a molding resin. Therefore, the thermal conductivity of the primary molded resin portion 32 is higher than that of a normal resin molded product. The molding resin is not particularly limited, such as a normal thermoplastic injection molding resin and engineering plastic, and a thermosetting molding resin material. Specific examples include acrylonitrile butadiene styrene resin (ABS resin), polyamide resin, polyethylene resin, polyester resin, polypropylene resin, polybutylene terephthalate resin, and polycarbonate resin (PC resin). . The heat conductivity of a general ABS resin or PC resin is 0.1 to 0.2 W / m · K. By mixing a high heat conductivity material, the heat conductivity of the primary molded resin portion 32 can be increased. It can be improved by an order of magnitude or more. However, if the ratio of the high thermal conductivity material is excessively increased, there is a problem that the impact resistance is lost. Therefore, attention should be paid to the distribution ratio of the high thermal conductivity material.

  As the secondary molding resin 41, a molding resin similar to the primary molding resin 31 can be used except that the secondary molding resin 41 is different from the primary molding resin 31 in that a high thermal conductivity material is not included.

  A method for manufacturing the two-color molded decorative article 43 using the above-described apparatus and materials will be described.

  First, the primary molding cavity mold 2 on which the primary decorative sheet 11 is disposed and the core mold 1 are closed to form a primary molding cavity 4, and a high thermal conductivity is formed in the primary molding cavity 4. The primary molded resin 31 containing the product is injected to form a primary molded decorative product 33 in which the primary decorative layer 13 is laminated on the surface of the primary molded resin portion 32 (see FIG. 1A).

  Here, the arrangement of the primary decorative sheet 11 on the cavity mold 2 for primary molding will be described in detail.

  When an insert sheet from which the base sheet 12 is not peeled is used as the primary decorative sheet 11, the primary decorative cavity 11 has a cavity surface on the base sheet 12 side or the primary decorative layer. Either of the 13 sides may be arranged. If the base sheet 12 side is disposed on the cavity surface, the base sheet 12 can prevent ink flow when the secondary molding resin 41 described later is injected. When the primary decorative layer 13 side is arranged on the cavity surface, the base sheet 12 is injected during the injection of the primary molding resin 31 even if the primary molding resin 31 contains a high thermal conductivity material and the fluidity is deteriorated. Can prevent ink flow. Here, if the primary decorative layer 13 is sandwiched between two sheets as the primary decorative sheet 11, the primary decorative layer is formed from both the primary molded resin 31 and the secondary molded resin 41. 13 can be protected by a sheet. The problem of cost increase and 2. Note that the thickness of the primary molding cavity 4 and the later-described secondary molding cavity 5 is reduced by increasing the thickness of the sheet, which may cause a problem of poor filling of the primary molding resin 31 and the secondary molding resin 41.

  When a transfer sheet is used as the primary decorating sheet 11, the primary decorating sheet 11 is disposed on the side of the base sheet 12 on the cavity surface of the primary molding cavity mold 2, and the primary sheet is peeled off even if the base sheet 12 is peeled off. The decorative layer 13 is left on the primary molded decorative product 33.

  After forming the primary molding ornament 33, the mold for opening the primary molding cavity mold 2 and the core mold 1 in a state where the core mold 1 holds the primary molding decoration 33, and facing the core mold 1. Is switched from the primary molding cavity mold 2 to the secondary molding cavity mold 3 and the secondary molding cavity mold 3 and the core mold 1 holding the primary molding decoration 33 are closed to form the primary molding decoration. A secondary molding cavity 5 is formed on the surface 33 by a gap. (See FIG. 1 (b)).

  Here, a transfer sheet is used as the primary decorative sheet 11, and the secondary molding cavity mold 3 and the primary molded decorative product 33 are held from the mold opening between the primary molding cavity mold 2 and the core mold 1. The base sheet 12 of the primary decorative sheet 11 may be peeled off from the primary molded decorative product 33 until the core mold 1 is closed.

  A secondary molding resin 41 is injected into the secondary molding cavity 5 to form a two-color molded decorative article 43 in which the secondary molded resin portion 42 is laminated on the surface of the primary molded decorative article 33 (FIG. 1 (c). )reference). Since the thermal conductivity of the primary molded resin portion 32 is higher than that of a normal resin molded product, the heat conducted to the primary decorative layer 13 is injected into the core mold through the primary molded resin portion 32 when the secondary molded resin 41 is injected. It can be dissipated towards one. As a result, the primary decorative layer 13 can withstand the flow resistance of the secondary molding resin 41 without being heated and softened by the secondary molding resin 41, and can maintain the position. Defects can be prevented.

  Finally, when the core mold 1 and the secondary molding cavity 3 are opened, a two-color molded decorative article 43 can be obtained (see FIG. 4A).

  Further, the secondary decoration sheet 21 in which the secondary decoration layer 23 is laminated on the base sheet 22 is used for the secondary decoration using a two-color molding decoration mold in which the secondary molding cavity mold 3 is disposed. The secondary mold cavity mold 3 on which the sheet 21 is arranged and the core mold 1 holding the primary molded decorative product 33 are closed to form the secondary mold cavity 5, and the secondary mold cavity 5 is formed. The secondary molded resin 41 may be injected to form a two-color molded decorative product 43 in which the secondary molded resin portion 42 and the secondary decorative layer 23 are sequentially laminated on the surface of the primary molded decorative product 33 ( (Refer FIG. 3, FIG.4 (b)).

  Here, a transfer sheet may be used as the secondary decorative sheet 21, and the base sheet 22 of the secondary decorative sheet 21 may be peeled from the two-color molded decorative article 43 after the two-color molded decorative article 43 is formed. Of course, in this case, the base sheet 22 side of the secondary decorative sheet 21 is arranged on the cavity surface of the cavity mold 3 for secondary molding.

  Other embodiments that the present invention can take are described below.

  The resin flow path of the primary molding resin 31 into the primary molding cavity 4 may be in the core mold 1 (see FIG. 1) or in the primary molding cavity mold 2 (see FIG. 5). ). The resin flow path of the secondary molding resin 41 into the secondary molding cavity 5 may be in the core mold 1 (see FIG. 1) or in the secondary molding cavity mold 3 (see FIG. 5). ).

  In the production of the two-color molded decorative article 43, a two-color molded decorative mold is provided with a plurality of core molds 1, and the movable plate or the rotary plate attached to the movable plate rotates. Can be placed (not shown). As the mold arrangement in the injection molding machine, the surface forming mold 1 and the coating film forming mold 2 are fixed to a stationary platen, and the core mold 1 is fixed to the movable platen of the injection molding machine or the rotating plate attached to the movable platen. That's fine. Alternatively, the core mold 1 may be fixed to a stationary platen, and the surface forming mold 1 and the coating film forming mold 2 may be fixed to a movable plate of an injection molding machine or a rotating plate attached to the movable platen. When installed in this manner, the core mold 1 and the secondary molding cavity for holding another primary molding decoration 33 while the primary molding decoration 33 is formed by a certain core mold 1 and the primary molding cavity mold 2. The two-color molded decorative article 43 is formed by the mold 3, that is, the two-color molded decorative article 43 can be manufactured simultaneously with the formation of the primary molded decorative article 33, which is preferable.

  A two-color molding decorative mold including a core mold 1, a primary molding cavity mold 2, and a secondary molding cavity mold 3 is prepared, and a primary color ink is formed on a base sheet 12 made of polyethylene terephthalate resin. The primary decorative sheet 11 which is a transfer sheet on which the decorative layer 13 is laminated, the ABS resin primary molding resin 31 containing 70 wt% of aluminum powder as a high thermal conductivity material, and a transparent acrylic resin 2 A two-color molded decorative article 43 was formed using the next molding resin 41.

  First, the primary molding cavity mold 2 and the core mold 1 in which the primary decorative sheet 11 is disposed so that the base sheet 12 faces the cavity surface are closed to form the primary molding cavity 4. The primary molding resin 31 is injected into the primary molding cavity 4 to form a primary molding decoration 33 in which the primary decoration layer 13 is laminated on the surface of the primary molding resin portion 32 (FIG. 1A )reference).

  Next, the cavity mold 2 for primary molding and the core mold 1 are opened while the core mold 1 holds the primary molded decorative article 33, and the base sheet 12 is peeled off from the primary molded decorative article 33. The mold opposite to the core mold 1 is switched from the primary molding cavity mold 2 to the secondary molding cavity mold 3 and the secondary molding cavity mold 3 and the core mold 1 holding the primary molding decoration 33 are molded. Closed to form a secondary molding cavity 5 (see FIG. 1B).

  Then, the secondary molding resin 41 is injected into the secondary molding cavity 5 to form a two-color molded decorative article 43 in which the secondary molded resin portion 42 is laminated on the surface of the primary molded decorative article 33 (FIG. 1). (See (c)).

  Finally, when the core mold 1 and the secondary molding cavity 3 are opened, a two-color molded decorative product 43 can be obtained (see FIG. 4A).

  When the secondary molding resin 41 was injected, the heat conducted to the primary decorative layer 13 could be dissipated toward the core mold 1 through the primary molding resin portion 32. As a result, the primary decorative layer 13 was able to withstand the flow resistance of the secondary molding resin 41 without being heated and softened by the secondary molding resin 41, so that the obtained two-color molding was obtained. The decorative product 43 was a beautiful product having no appearance defect due to the ink flow of the primary decorative layer 13.
