Description

  The present invention relates to an illuminating panel disposed in an air conditioner operating unit, a shift lever operating unit, or the like of an automobile, and having a metallic decoration on its design surface.

  Illuminated panels arranged in an air conditioner operation unit, a shift lever operation unit, and the like of an automobile are well known (for example, Patent Documents 1 and 2). Such an illuminating panel is a resin molded product having a design surface formed on the surface, and has an illuminating part having translucency on the design surface, and the illumination part shines when illuminated from the back side of the panel. It has become.

  Further, some conventional illumination type panels are provided with a metallic decoration having a metallic luster on the design surface. FIG. 10 shows a conventional lighting panel 1a provided with a metallic decoration 6a, which is disposed in a shift lever operation unit of an automobile. Such an illumination panel 1a is provided with a fixing portion 3a for screwing on the outer peripheral portion of a flat panel main body 2a, and a lever opening through which a shift lever L passes in the center of the panel main body 2a. 7a is formed.

  The design surface 4a is formed over the entire top surface of the panel body 2a. On the design surface 4a, a rectangular display area 8a on which the letters “P”, “R”, “N”, and “D” are written is formed on the left side of the lever opening 7a. Each character of the region 8a constitutes the illumination unit 5a. That is, the characters “P”, “R”, “N”, and “D” in the display area 8a are illuminated when the illuminated panel 1 has translucency and is illuminated from the back side. Will shine. On the other hand, the metallic decoration 6a is provided at the peripheral edge of the lever opening 7a.

  As shown in FIGS. 10 and 11, a print film 10a on which a predetermined pattern is printed is laminated and integrated on the upper surface of the panel body 2a, and the design excluding the metallic decoration portion 6a is formed by the print film 10a. A surface 4a is formed. On the other hand, the metallic decoration 6a is formed by metal plating. The reason why the metallic decoration 6a is separately formed in this way is that the glitter ink printed on the printing film cannot obtain a sufficient metallic luster.

  In the conventional illumination type panel 1a, the metallic decoration 6a is formed by metal plating and the remaining design surface is formed by the printing film 10a. Therefore, as shown in FIGS. The resin component 24 laminated on the metal plate and the metal-plated resin component 25 are separately molded, and both components are assembled by screwing or caulking. Moreover, in the conventional illumination type panel 1a, as shown in FIG. 11, the back side of the printing film 10a is lined with a light transmissive resin portion 21c made of a light transmissive resin so that illumination from the back side can be transmitted. Furthermore, a light-impermeable resin portion 22a made of a light-impermeable resin is laminated on the back surface side. In addition, 23a in FIG. 11 is an opening formed in the light-impermeable resin portion 22a in order to apply illumination from the back surface to the illumination portion 5a, and 26 is a screw for assembling the two resin parts 24 and 25.

JP 2007-112196 A JP 2007-331185 A

  As described above, in the conventional illuminating panel 1a, the resin base material 9a is constituted by the resin component 24 laminated with the printing film 10a and the resin component 25 plated with metal. The two resin parts 24 and 25 must be separately molded and further assembled, and many steps are required to manufacture the lighting panel 1a.

  As a result of intensive studies to solve the above problems, the inventor has conceived that a glittering film incorporating a thin metal layer is laminated and integrated on a resin substrate simultaneously with a printed film, instead of a plated resin part. . However, when the film insert injection molding is performed by setting the printing film and the glitter film at the same time in the mold, there is a problem that the injected molten resin is likely to leak to the surface side of the film, and the aesthetic appearance of the design surface is easily impaired. . That is, as shown in FIG. 12, when the printing film 10a and the glitter film 11a are set on the mold surface, the two pieces of films 10a and 11a are placed next to each other in order to form a substantially unbroken design surface. Although it is necessary to set on one mold surface of the molds D4 and D5, when the molten resin P is injected onto the mold surface, between the recess x1 for setting the printing film 10a and the recess x2 for setting the glitter film 11a. A turbulent flow is generated in the portion of the convex portion y formed on the surface, and in the vicinity of the convex portion y, the molten resin P easily enters the gap between the end portions of the films 10a and 11a and the mold surface.

  The present invention is an attempt to solve such a problem, and it is an object of the present invention to provide an easily illuminated panel including a metallic decoration part and a method for manufacturing the same.

  The present invention is a method for manufacturing an illuminating panel having an illumination part that shines by illumination from the back side and a metallic decoration part having a metallic luster on a design surface, and the illumination part is provided on a mold surface of one mold. A film mounting step for setting a printing film on which a predetermined pattern is printed and a glitter film for forming a metallic decoration portion to be adjacent to each other, and after the film mounting step, the mold is closed, Separate cavities are formed on the back side of the printed film and the back side of the glitter film so as to reach at least the adjacent ends of each film, and a light transmissive first resin is injected into each cavity. A first molding step for molding a decorative part formed by laminating the first resin on the printed film, and a bright part obtained by laminating the first resin on the bright film, and the first molding step. After the, While holding the decorative part and the bright part on the mold surface of one mold, replace the other mold, inject the second resin into the cavity containing the decorative part and the bright part, And a second molding step for obtaining an integral molded product obtained by laminating a second resin on a bright part.

  In the present invention, “light transmissive” is a property of transmitting light and includes “transparent” and “translucent”. On the other hand, “light-impermeable” refers to a property that is not “light-transmissive”. Moreover, the surface of a printing film and a brightness film points out the side exposed to the surface of an illumination type panel, and a back surface points out the other side.

  According to the production method of the present invention, the resin base material can be appropriately laminated on the printing film and the glitter film set so as to be adjacent to the mold surface of the mold. That is, as shown in FIG. 1A, after setting the printing film 10 and the glitter film 11 on the mold surface of one mold D1 so as to be adjacent to each other, the other mold D2 is closed, and the printing film 10 and the glitter film 11 are glittered. The film 11 is separated into separate cavities C1 and C2. In this state, the first transparent resin T is injected into each of the cavities C1 and C2, and the decorative component 30 formed by laminating the first resin T on the printing film 10 and the first on the glitter film 11 are provided. A bright component 31 formed by laminating the resin T is molded. In the first molding step, since the cavity C1 including the printing film 10 and the cavity C2 including the bright film 11 are separately formed, turbulence may occur at the boundary portion between the films 10 and 11. Instead, the injected first resin T is laminated without leaking from the end portions of the films 10 and 11 to the surface side.

  Subsequently, in the second molding step, the other mold D3 is replaced, and the second resin U is injected in a state where the decorative component 30 and the bright component 31 are accommodated in the same cavity C3. And the luminous component 31 are laminated to obtain an integral molded product. At this time, as shown in FIG. 1B, since the printing film 10 and the glitter film 11 are firmly backed by the first resin T, even if turbulent flow occurs in the cavity C3, the second resin U does not leak to the front side of each film 10,11.

  In the manufacturing method of the illumination type panel of this invention, it is proposed that a brilliant film is provided with the thin metal layer. Since the thin metal layer is made of approximately 100% metal, this manufacturing method achieves a metallic luster similar to metal plating that cannot be achieved by printing bright ink containing only 20-30% metal. it can. Moreover, when employ | adopting such a brilliant film, it is desirable for a brilliant film to equip the back surface side of the said thin film metal layer with the heat insulation resin layer of thickness 100 micrometers or more. If such a heat insulating resin layer is provided, it is possible to suppress whitening of the thin film metal layer due to the heat of the molten resin laminated on the back surface side during film insert injection molding.

  Another embodiment of the present invention is an illumination type panel having an illumination part that shines by illumination from the back side and a metallic decoration part having a metallic luster on a design surface, and a printed film on which a predetermined pattern is printed And a glitter film having a thin metal layer are laminated and integrated so as to be adjacent to the surface of the resin base material by film insert injection molding, and the resin base material is at least a light-transmitting first material. It is comprised by resin, This 1st resin is an illumination type panel characterized by being separately formed so that it may laminate | stack on each edge part which adjoins at least the said printing film and the said brightness | luminance film. Since this illumination type panel can be manufactured by the above manufacturing method, it can be manufactured at a lower cost than conventional ones, and defective molding can be reduced.

  As described above, according to the method for manufacturing an illuminated panel of the present invention, a printed film and a bright film can be laminated and integrated on a resin base material by a series of film insert injection molding. Compared with the method, it can be manufactured with a smaller number of steps, and the mold cost can be reduced. In addition, according to such a manufacturing method, in the case of film insert injection molding, since there is little risk of molten resin entering the gap between the inserted film and the mold surface and leaking to the surface of the film, molding defects can be reduced. There are advantages.

  Moreover, since the illumination type panel of this invention can be manufactured with a manufacturing method with few processes and few molding defects as mentioned above, it can implement | achieve a cheap and high quality illumination type panel.

  The illuminating panel of the present invention is disposed on an air conditioner operating section or shift lever operating section for an automobile, a smart key, a scuff plate, a meter bezel, a handle bezel, or the like.

  The illumination type panel of the present invention is formed by laminating a print film and a glitter film on the surface of a resin base material. The same thing as the existing illumination type panel is employable as 1st resin and 2nd resin used as the material of a resin base material. Specific examples include ABS resin, polycarbonate ABS, polycarbonate, polypropylene, and acrylic resin. The first resin is used to back the printing film that forms the illumination part, and thus needs to be a light-transmitting resin. However, the second resin does not need to back the printing film directly. It does not need to be transparent. The resin base material can also contain other resins in addition to the first resin and the second resin.

  The printing film is obtained by forming a printing layer on a resinous film substrate, and the same printing film as that for forming the design surface of an existing illumination panel can be employed. The printing layer can be formed by a printing method similar to that for existing printing films, such as gravure printing, flexographic printing, and offset printing. The printing layer can be provided on both the front and back sides of the film substrate, or can be provided on both sides. Further, the formed printing layer may be further covered with a protective layer.

  The glitter film having metallic luster is desirably provided with a thin metal layer. The thin film metal layer is a thin film formed of almost 100% metal, and examples thereof include a vacuum deposited film formed by vacuum deposition on a film substrate, and a sputtered film formed by sputtering on a film substrate. The material for the thin film metal layer is not particularly limited, but preferred examples include aluminum, indium, nickel, chromium, and stainless steel. The thickness of the thin metal layer is not particularly limited, but is preferably 500 mm or more. With such a thickness, a sufficient metallic luster can be obtained.

  Moreover, it is desirable that the bright film has a heat insulating resin layer on the back side of the thin metal layer. If it is set as this structure, in the case of film insert injection molding, it can protect a thin film metal layer from the heat | fever of the molten resin inject | emitted, and can suppress that a thin film metal layer whitens. The material of the heat insulating resin layer is not particularly limited, but ABS resin or polypropylene is preferably used. The heat insulating resin layer may be a multi-layered resin layer. The thickness of the heat insulating resin layer needs to be 100 μm or more, and preferably 150 μm or more. If it is 100 μm or more, the thin film metal layer can be protected from heat during film insert injection molding, and whitening of the thin film metal layer can be sufficiently suppressed. If the thickness is 150 μm or more, the thin film metal layer can be surely whitened. Can be suppressed. From the viewpoint of moldability, the thickness of the heat insulating resin layer is preferably 500 μm or less.

  The design surface according to the illumination type panel of the present invention is not limited as long as at least the illumination part is formed of a printed film and the metallic decoration part is formed of a glitter film, and other parts of the design surface are a print film, a glitter film, Moreover, it can form with another structure. The “metallic decoration part” according to the present invention refers to a decorative part having a metallic luster equivalent to metal plating, and the inferior metallic luster decoration formed by bright ink is referred to as the “metallic decorative part” of the present invention. Is not included.

  In the manufacturing method of the illumination type panel of this invention, it is desirable to shape and cut the printing film and the glitter film set on the mold surface in advance. For forming each film, known methods such as vacuum forming, pressure forming, and vacuum / pressure forming can be used. Also, a known method can be used for cutting each film.

  The film attachment process, the first molding process, and the second molding process can be performed in the same manner as in a normal film insert injection molding unless otherwise specified. In the present invention, in the first molding step, it is sufficient to separately form different cavities on the back side of the print film and the back side of the glitter film so as to extend at least to the adjacent end portions of the films. However, it is desirable to form each cavity separately so as to cover all the ends of each film. According to such a method, in the first molding step, all ends of the printed film and the glitter film are lined with the first resin, respectively. Therefore, in the second molding step, the molten resin leaks from the end of each film. It can prevent more reliably.

  In the present invention, it is desirable that the gap between the end portions of both films be xx to xx mm in the portion where the print film and the glitter film are adjacent to each other. If the gap between the end portions of both films is smaller than xx mm, the manufacture of the mold becomes complicated. On the other hand, if the gap between the end portions of both films is larger than xx mm, the aesthetic appearance of the design surface is impaired by the gap.

  The illumination type panel 1 of a present Example is an illumination type panel used for the shift lever operation part of a motor vehicle. As shown in FIGS. 2 and 3, the illuminating panel 1 has the same outer shape as the conventional illuminating panel 1a shown in FIG. That is, the illumination type panel 1 is mainly composed of a flat panel main body 2 provided with a substantially rectangular lever opening 7 through which the shift lever L passes. The illuminating panel 1 includes a plurality of fixing portions 3 having through holes formed in the outer peripheral portion of the panel main body 2, and is screwed to a shift lever operation portion main body (not shown) via the fixing portions 3. .

  As shown in FIGS. 4 and 5, the resin base material 9 includes a light-transmitting resin portion 21 made of a light-transmitting white resin (first resin) and a light-impermeable black resin (second resin). It is an integrally molded product comprising the light-impermeable resin part 22 made of The light transmissive resin portion 21 is separately formed into a portion 21 a that backs the entire glitter film 11 and a portion 21 b that backs the entire print film 10. The light-impermeable resin portion 22 is laminated on the back side of the light-transmissive resin portion 21, and the two portions 21 a and 21 b formed separately from the light-transmissive resin portion 21 are interposed via the light-impermeable resin portion 22. Connected.

  The resin base 9 is provided with an illumination opening 23 in the light-impermeable resin portion 22 below the illumination portion 5. According to such a configuration, the illumination from the back surface side can be applied to the printing film 10 without being blocked by the light-impermeable resin portion 22.

  As shown in FIGS. 4 and 5, the glitter film 11 is laminated on the surface of the peripheral portion of the lever opening 7 to form a metallic decoration 6. As shown in FIG. 6, the glitter film 11 includes a thin film metal layer 15, a heat insulating resin layer 16 provided on the back surface of the thin film metal layer 15, and a surface resin layer 17 provided on the surface side of the thin film metal layer 15. It consists of.

  The thin film metal layer 15 is an aluminum thin film having a thickness of about 1000 mm formed by vacuum deposition or sputtering. The surface resin layer 17 is composed of a transparent PET resin layer 17b having a thickness of about 30 μm in contact with the surface of the thin film metal layer 15, and a transparent PMMA resin layer 17a in contact with the surface of the PET resin layer 17b. The PET resin layer 17b constitutes a base material when the thin film metal layer 15 is formed, and the PMMA resin layer 17a physically protects the thin film metal layer 15. The heat insulating resin layer 16 is composed of a light-transmitting ABS resin film having a thickness of about 200 μm, and protects the thin metal layer 15 from the heat of the molten resin during film insert injection molding. Work. The glitter film 11 can be manufactured by a well-known and conventional method. For example, it can be manufactured by producing a PET resin film obtained by vacuum-depositing aluminum, further adhering a PMMA resin film to the front surface side, and adhering an ABS resin film to the rear surface side.

  The print film 10 is laminated on substantially the entire upper surface of the panel body 2 and forms the entire design surface 4 excluding the metallic decoration portion 6. As shown in FIG. 7, the printed film 10 includes a transparent base layer 13 made of PMMA resin and having a thickness of about 200 μm, and an opaque back side printed layer 14 formed on the back side of the base layer 13. Composed.

  The back printed layer 14 is made of an opaque ink having a thickness of about 20 μm, and the decoration of the design surface 4 excluding the metallic decoration 6 is formed by the back printed layer 14. Here, as shown in FIG. 7, the portion 14 a of the back surface printed layer 14 that forms the illumination portion 5 is formed of translucent white ink, while the portion that forms the display region 8 around the illumination portion 5. 14b is formed of black ink that does not transmit light. When light is applied to the vicinity of the illumination unit 5 from the back side, only the portion 14a forming the illumination unit 5 is transmitted, and the illumination unit 5 is illuminated. It will be visually recognized. Further, the portion of the back printed layer 14 other than the display region 8 is decorated with light-impermeable silver ink.

  Next, the manufacturing method of the illumination type panel 1 of a present Example is demonstrated. The illumination panel 1 is manufactured by laminating and integrating the printing film 10 and the glitter film 11 on the resin base material 9 by the film insert injection molding described below.

  First, as a pre-process of film insert injection molding, the printing film 10 and the glitter film 11 are each shaped and cut, and preformed into a shape suitable for insertion into a mold. For this preforming, a known preforming method in conventional general film insert injection molding can be suitably employed. For example, each film can be shaped by vacuum forming, pressure forming, vacuum pressure forming or the like.

<Film attachment process>
In the film insert injection molding, first, as shown in FIG. 8A, the shaped and cut print film 10 is set on the lower mold D1 so that the surface is in contact with the mold surface. At the same time, the shaped and cut glitter film 11 is set on the lower mold D1 at a position adjacent to the inside of the printing film 10 so that the surface thereof is in contact with the mold surface.

<First molding process>
Next, as shown in FIG. 8B, the first upper mold D2 is closed with respect to the lower mold D1. At this time, the upper mold D2 and the lower mold D1 separate and form the two cavities C1 including the printing film 10 and the cavity C2 including the glitter film 11, and the set printing film 10 and glitter film 11 are separated from each other. It will be separated into cavities C1 and C2.

  Next, as shown in FIG. 8C, a light-transmitting resin (first resin) T is injected into the cavity C1 in which the printing film 10 is set and the cavity C2 in which the glitter film 11 is set. The decorative component 30 formed by laminating the light transmissive resin T on the back surface side of the printing film 10 and the glittering component 31 formed by laminating the light transmissive resin T on the back surface side of the glitter film 11 are formed.

<Second molding step>
After molding the decorative component 30 and the bright component 31, as shown in FIG. 9D, the upper mold is replaced with the decorative component 30 and the bright component 31 fitted in the lower mold D1, and the lower mold D1 is replaced. On the other hand, the second upper mold D3 is closed. At this time, a single cavity C3 including the decorative component 30 and the bright component 31 is formed between the upper mold D3 and the lower mold D1.

  Finally, as shown in FIG. 9 (e), a light-impermeable resin (second resin) U is injected into the cavity C1 in which the decorative component 30 and the bright component 31 are set. As shown, the illumination type panel 1 formed by laminating and integrating the light-impermeable resin U on the back surfaces of the decorative component 30 and the bright component 31 is obtained.

  According to the above manufacturing method, the printing film 10 and the glitter film 11 can be laminated and integrated with the resin base material 9 by a series of film insert injection molding. For this reason, the illumination type panel 1 of a present Example can be manufactured cheaply and easily compared with the conventional illumination type panel. That is, when manufacturing the conventional illumination type panel 1a (see FIGS. 10 and 11), the resin component 24 on which the printing film 10a is laminated is manufactured by film insert injection molding, and the metal-plated resin component 25 is separately provided. It was necessary to manufacture and attach two resin parts 24 and 25. On the other hand, in the illumination type panel 1 of this embodiment, the glitter film 11 forming the metallic decoration portion 6 is laminated and integrated with the resin base material 9 simultaneously with the printing film 10 by film insert injection molding. Compared with the illumination type panel 1a, it is possible to reduce processes such as molding and assembling of metal-plated resin parts, and to save labor and mold costs.

  In the manufacturing method of the present embodiment, as shown in FIGS. 8 and 9, first, the light-transmitting resin (first resin) is obtained in a state where the printing film 10 and the glitter film 11 are separated into separate cavities C1 and C2. ) The two pieces of films 10 and 11 are separately lined with light-transmitting resin T by injecting T. According to this manufacturing method, when the light transmissive resin T is injected, turbulent flow does not occur at the boundary between the two pieces of the films 10 and 11, and the light transmissive property is appropriately applied to the back side of each of the films 10 and 11. Resin T can be laminated. Moreover, when injecting the light-impermeable resin (second resin) U, the end portions of the two pieces of films 10 and 11 are lined with the light-transmitting resin T, so that turbulence occurs. Also, the molten resin does not enter the surface side from the end portions of both films 10 and 11. Therefore, according to this manufacturing method, there is no possibility that the resin constituting the resin base material 9 leaks to the surface side of the printing film 10 or the glitter film 11, and the aesthetic appearance of the design surface 4 is not impaired, thereby suppressing molding defects. Can do.

  Further, in the illumination type panel 1 of the present embodiment, the glitter film 11 includes the heat insulating resin layer 16 on the back surface side of the thin metal layer 15, so that it is injected onto the back surface of the printing film 10 during film insert injection molding. The heat of the molten resin is not easily transmitted to the thin film metal layer 15, and the thin film metal layer 15 is not whitened by the heat of the molten resin. Therefore, in the illumination type panel 1 of the present embodiment, the thin metal layer 15 can realize the metallic decoration portion 6 rich in metallic luster similar to the metal plating.

  In addition, the illumination type panel in this invention can add a various change in the range which does not deviate from the summary of not only the form of the said Example but this invention. For example, in the illumination type panel of the embodiment, the substantially entire back surface of the printing film and the glitter film is lined with a light-transmitting resin (first resin). In the present invention, at least the printing film and the glitter film are used. It is only necessary that the adjacent end portions are lined with a light-transmitting resin. Further, in the above embodiment, the glitter film has a configuration in which only the metallic decoration part is formed. For example, the surface of the glitter film is partially covered with a printing layer, and the metallic part is covered with the coating part. A design surface other than the decorative portion may be formed.
