It is characterized by that.

In addition, as described in claim 3, the method for producing a simultaneous molding double-sided decorative product according to the present invention uses the mold simultaneous double-sided decorative mold according to claim 1, and uses the mold bottom of the first mold. The end of the first decorative film is sandwiched by the sandwiching member and the end opposite to the end of the first decorative film is sandwiched by the rear sandwiching member. pinching the other hand placed along a second decorative film into a mold bottom of the second type, the first type and the second type and closed type, then the first decorative film between the second decorative film A molding resin is injected from the injection port of the first mold to mold a resin molded product, and at the same time, a decorative film is adhered to both the front and back surfaces of the resin molded product to obtain a molded simultaneous double-sided decorative product.

According to a fourth aspect of the present invention, there is provided a method for producing a simultaneous molding double-sided decorative product according to the present invention, wherein the mold bottom of the first mold is formed using the simultaneous molding double-sided decorative mold according to the second aspect. The end of the first decorative film is sandwiched between the first decorative film and the end of the first decorative film is sandwiched by the first sandwiching member, and the end opposite to the end of the first decorative film is sandwiched rearward sandwiched between members, sandwiched by second gripping members to exit end of the second decorative film causes the other hand along the second decorative film into a mold bottom of the second type, the first type and the second type The mold is closed and a molding resin is injected between the first decorative film and the second decorative film from the injection port of the first mold to form a resin molded product. At the same time, the decorative film is formed on both the front and back surfaces of the resin molded product. Are bonded to form a double-sided decorative article.

  In this invention, in order to prevent the molding resin injected to the injection port side end portion of the first decorative film along the mold bottom of the portion not covering the injection port of the first mold having the injection port from colliding. The molding simultaneous double-sided decorating mold has a sandwiching member for sandwiching the exit side end of the decorative film in the first mold.

  Therefore, the following effects are produced. Since the injection port side end of the decorative film on the first mold side is fixed by the sandwiching member, the fixing force is strong and stable, and the injection film side end of the decorative film is caused by the flow force of the injected molding resin. Can be prevented completely, and the molding resin does not sink between the first mold and the decorative film. The same effect can be obtained even when the decorative film has a large thickness.

  The molding simultaneous double-sided decorative mold of this invention will be described.

  The molding simultaneous double-sided decorative mold of this invention has a first decorative film along the bottom of the mold that does not cover the injection port of the first mold having the injection port and a second decoration on the bottom of the second mold. After aligning the film, the first mold and the second mold are closed, and a molded resin is injected between the first decorative film and the second decorative film through the injection port of the first mold, and the resin molded product. Is a molding simultaneous double-sided decoration mold used in the simultaneous molding and decorating method in which a decorative film is adhered to both the front and back surfaces of the resin molded product, and the first decorative film is shot along the first mold. The first mold has a sandwiching member that prevents the molded resin injected by sandwiching the outlet side end portion from colliding with the injection port side end portion of the first decorative film.

  More specifically, as shown in FIGS. 1 to 3, the mold includes a first mold and a second mold. The first mold has an injection port, a fitting recess having a slope for sandwiching a film at the mold bottom, and a first process. It has a pinching member that has a shape that can be fitted into the fitting recess via a decorative film, and the pinching member can be fitted into the fitting recess and detached from the fitting recess via an air cylinder via a rod. There are things that are characterized by that.

  The 1st type | mold 1 and the 2nd type | mold 2 are the 1st decorating film 4 and the 2nd decorating film 5 by sandwiching the 1st decorating film 4 and the 2nd decorating film 5, and closing the type | mold. A molded resin is injected into the space formed between the injection port 3 of the first mold 1 to form a resin molded product, and a decorative film is adhered to both the front and back surfaces of the resin molded product to obtain a molded simultaneous double-sided decorative product. It is a mold. Examples of the mold including the first mold 1 and the second mold 2 include an injection mold.

  The 1st type | mold 1 is a metal mold | die which has the injection port 3, Comprising: The 1st decorating film 4 is put along the type | mold bottom of the part which does not cover the injection port 3. FIG. The injection port 3 is an opening for injecting molten molding resin between the first decorative film 4 and the second decorative film 5. The injection port 3 is formed at a position that is not covered by the injection port side end 6 of the first decorative film 4. This is to prevent the first decorative film 4 from blocking the injection port when the molding resin is injected. The surface of the mold bottom along which the first decorative film 4 of the first mold 1 is aligned may be a flat surface or a concave surface. It is designed appropriately according to the required three-dimensional shape of the resin molded product. As a concrete 1st type | mold 1, there exists what has the fitting recessed part 14 which has the slope for film clamping on the type | mold bottom (refer FIG. 2).

  The first mold 1 has a sandwiching member 7 that sandwiches the injection port side end portion 6 of the first decorative film 4 so that the injected molding resin does not collide with the injection port side end portion 6 (FIG. 8). reference). The specific sandwiching member 7 has a shape that can be fitted into the fitting recess 14 via the first decorative film 4, and the sandwiching member 7 is fitted into the fitting recess by the air cylinder 10 via the rod 11. There are some which can be fitted and detached from the fitting recess (see FIG. 2).

  The sandwiching member 7 has a substantially trapezoidal cross section (see FIGS. 1 to 4 and FIGS. 7 to 8). For example, when the width of the resin molded product to be obtained is 50 mm, the length of the sandwiching member 7 is preferably 70 mm. This is to counter the tension in the longitudinal direction of the decorative film. The reason why the shape of the sandwiching member 7 is as described above is that the decorative film can be easily sandwiched against the tension of the decorative film, and the generation of wrinkles can be suppressed. The sandwiching member 7 can be shaped so that the surface of the sandwiching member 7 is flush with the surface of the first mold 1 by sandwiching a decorative film (FIGS. 1, 2, and 4). reference). Of the sandwiching member 7, the width of the slope corresponding to the slope 13 for film sandwiching is preferably 3 to 5 mm (see FIG. 2). If it is less than 3 mm, the pinching force will be weak, and it will be easy for floating and turning up. If it exceeds 5 mm, the surface area of the decorative film will need to be increased by that amount, which is not economical. This is because the displacement of the decorative film increases. The angle of the film sandwiching slope 13 can be 10 to 45 °. In particular, 25 ° is preferable. If the angle is less than 10 °, the strength of the sandwiching member 7 is weakened and the tip is easily broken and easily damaged. If the angle exceeds 45 °, the decorative film needs to be bent at a large angle. This is because it becomes easy to apply to a decorative film that is particularly rigid and difficult to deform. In order to increase the strength of the sandwiching member 7, the sandwiching member 7 can be made thick (see FIG. 3). In this case, the space 12 itself into which the molding resin is injected is deformed. However, this may be done in a portion where the sandwiching member 7 is present in the space 12 in which the molding resin is injected. This is because it is the part that is cut out after the molded double-sided decorative product is obtained (see FIG. 6). The molding simultaneous double-sided decorative product in FIG. 6 is a combination of decoration (characters and frame-shaped light colored portion) by the first decorative film 4 and decoration (frame-shaped dark colored portion) by the second decorative film 5. It is a simultaneous molding double-sided decorative product in which the decoration (characters and frame-like light colored part) by the 1 decorative film 4 is observed through the translucent part of the second decorative film 5.

  As a pinching member, you may have the back pinching member 73 which pinches | interposes the edge part on the opposite side instead of the injection port side edge part 6 of the 1st decorating film 4 (refer FIG. 7). Since the decorative film can be firmly fixed by the first mold by sandwiching not only the injection port side end portion 6 but also the opposite end portion of the decorative film simultaneously or non-simultaneously, the decorative film It is possible to prevent the generation of wrinkles and fluttering, and to prevent the injected molding resin from entering between the first decorative film 4 and the first mold.

  As a driving mechanism of the sandwiching member 7, there are an air cylinder system, a cam system, a mold closing force utilization system, and the like. 1 to 5 illustrate an air cylinder system, which includes an air cylinder 10 and a rod 11 incorporated in a fixed mold 1, and a sandwiching member 7 is fixed to the tip of the rod 11. This is a mechanism in which the rod 11 is pushed up by the compressed air in the air cylinder 10. In order to make the decorative film less likely to be scratched, it is effective to adopt a cam system. This is because the degree of movement of the sandwiching member 7 can be finely adjusted. In particular, it is suitable when a decorative film using a base sheet that is rigid and hardly deforms is softly sandwiched. In addition, the decorative film is sandwiched by the air cylinder method when the first mold 1 and the second mold 2 are opened. When the mold is closed, the cam structure contributes to the mold closing force of the mold, and the decorative film is sandwiched. It is also possible to make the structure stronger. In particular, a decorative film using a base sheet that is rigid and difficult to deform prevents the decorative film from floating due to insufficient pinching force and secures a wider passage for molding resin such as polycarbonate resin with low fluidity. This is preferable.

  The second mold 2 is a mold that allows the second decorative film 5 to follow. The surface along which the second decorative film 5 of the second mold 2 is aligned may be a flat surface or a concave surface. It is designed appropriately according to the required three-dimensional shape of the resin molded product.

  You may have the said pinching member 7 in both the 1st type | mold 1 and the 2nd type | mold 2. In other words, in this aspect, the first decorative film 4 is placed along the mold bottom of the portion that does not cover the injection port 3 of the first mold 1 having the injection port 3 and the second decorative film is formed on the mold bottom of the second mold 2. 5, the first mold 1 and the second mold 2 are closed, and a molding resin is injected from the first mold injection port 3 between the first decorative film 4 and the second decorative film 5. And a molding simultaneous double-sided decorative mold used in a simultaneous molding method for molding a resin molded product and simultaneously adhering a decorative film to both the front and back surfaces of the resin molded product, the injection port of the first decorative film 4 The first mold has a first sandwiching member 71 that prevents the molded resin injected by sandwiching the side end portion 6 from colliding with the injection port side end portion 6 of the first decorative film 4, and the second decoration. The molded resin injected by sandwiching the injection port side end 6 of the film is the second decoration. The second gripping members 72 so as not to impinge on the exit-side end portion 6 of Irumu 5 having the second type 2. The shape and driving mechanism of the first sandwiching member 71 and the second sandwiching member 72 can be the same as those of the sandwiching member 7 described above. The formation positions of the first sandwiching member 71 and the second sandwiching member 72 may be formed at positions facing directly in front (see FIG. 4) or at positions not facing each other.

  The manufacturing method of the simultaneous molding double-sided decorative article of this invention is demonstrated.

  A manufacturing method in the case of using a mold having the sandwiching member 7 only in the first mold 1 will be described. First, the first decorative film is placed along the bottom of the first mold, and the injection opening side end 6 of the first decorative film is sandwiched by the sandwiching member, while the second decorative film is placed on the bottom of the second mold. 5 along. The first decorative film 4 is placed along a portion that does not cover the injection port 3 of the first mold 1. This is to prevent the first decorative film 4 from blocking the injection port 3 when the molding resin is injected. Further, the second decorative film 5 is placed along the second mold 2 so as to cover the part corresponding to the first decorative film 4 and the part corresponding to the injection port 3 of the first mold 1. The reason for covering the portion corresponding to the first decorative film 4 is to form the decorative film on both the front and back surfaces of the resin molded product. The part corresponding to the injection port 3 of the first mold 1 is also covered by the second mold 2 and the second mold 2 because the injection port side end of the second decorative film 5 is floated or turned up by the molding resin. This is to prevent the molding resin from entering between the decorative film 5. More specifically, the first decorative film 4 is placed along the mold bottom of the first mold 1 and the sandwiching member released from the fitting recess is operated by operating the air cylinder 10 via the rod 11 to thereby perform the first processing. The injection port side end portion 6 of the decorative film 4 is sandwiched between the fitting recess and the sandwiching member 7.

  In order to set the first decorative film 4 and the second decorative film 5 to the first mold 1 and the second mold 2, the long decorative film is continuously fed by the decorative film feeder. Alternatively, decorative films cut into a predetermined shape by a Thomson mold or the like may be set one by one. A vacuum suction hole (not shown) is formed on the slope 13 for sandwiching the first film of the fitting recess 14 of the first mold 1 to assist the first mold 1 with the injection port end 6 of the first decorative film 4. Alternatively, suction adhesion may be performed. Further, the first decorative film 4 may be fixed to the first mold 1 with a clamp member (not shown). Moreover, you may heat the 1st decorating film 4 with a heating means (not shown).

  The position where the second decorative film 5 is placed along the second mold 2 is as described above.

  The relative arrangement of the decorative portions of the first decorative film 4 and the second decorative film 5 is the character or design of the second decorative film 5 on the portion having the translucency of the first decorative film 4. Etc. should be arranged. By doing so, when viewed from the first decorative film 4 side, the design of the first decorative film 4 (for example, a black frame) and the design of the second decorative film 5 (for example, a white frame and characters) are combined. Therefore, it looks as if the design of the first decorative film 4 (for example, a black frame) and the design of the second decorative film 5 (for example, a white frame and characters) are formed on the same plane. Because.

  Next, the first mold and the second mold are closed, and then a molded resin is injected between the first decorative film and the second decorative film from the injection port of the first mold to obtain a resin molded product. At the same time as molding, a decorative film is adhered to both the front and back surfaces of the resin molded product to obtain a molded simultaneous double-sided decorative product. When the molding resin is injected from the injection port 3, the injection port side end portion 6 of the first decorative film 4 is sandwiched between the mold bottoms of the first mold 1 by the sandwiching member. The side end does not float or turn up, and molding resin does not sink. When the first decorative film 4 is a type that is used by peeling the base sheet, the base sheet is peeled off when the first mold 1 and the second mold 2 are opened or after the mold is opened. Examples of the molding resin include acrylic resin, ABS resin, polycarbonate resin, polypropylene resin, and polylactic acid resin. Molding resin may have translucency. The reason is that the design of the second decorative film 5 can be seen through from the first decorative film 4 side, and the design of the first decorative film 4 can be seen through from the second decorative film 5 side. is there.

In addition, as a specific example of the basic layer structure of the first decorative film 4 and the second decorative film 5 used in the present invention, a base sheet, a release layer, a release layer, a design layer, and an adhesive layer are sequentially laminated. There is something. Note that when the base sheet is used without being peeled, the release layer and the release layer are unnecessary. Examples of the material for the base sheet include resin sheets such as acrylic resin, polycarbonate resin, polyolefin resin, polyester resin, and ABS resin. Alternatively, there are composites obtained by laminating each of the above sheets. As the film thickness of the substrate sheet, a film having a thickness of 10 μm to 200 μm can be used. More specifically, a biaxially stretched polyester film having a film thickness of 38 μm, 70 μm, or 188 μm and a biaxially stretched polylactic acid film having a film thickness of 100 μm are available. Examples of the material of the release layer include melamine resin release agents and silicone resin release agents. Examples of the material for the release layer include acrylic resins, polyester resins, and polyvinyl chloride resins. As a peeling layer, there exists what provided the hard-coat function using the urethane acrylate resin. The design layer is usually formed as a printing layer. As a material of the printing layer, it is preferable to use a colored ink containing a resin such as an acrylic resin, a polyvinyl resin, a polyamide resin, or a polyester resin as a binder and a pigment or dye of an appropriate color as a colorant. The dry film thickness of the printed layer is generally 1 μm to 50 μm. The pattern layer may be a metal thin film layer or a combination of a printed layer and a metal thin film layer. The metal thin film layer is formed by a vacuum deposition method, a sputtering method, an ion plating method, or the like. The material of the adhesive layer includes acrylic resin and vinyl resin. A heat-sensitive or pressure-sensitive resin suitable for the molding resin is appropriately used. For example, when the material of the molding resin is a polyacrylic resin, a polyacrylic resin may be used. In addition, when the molding resin material is polyphenylene oxide / polystyrene resin, polycarbonate resin, styrene copolymer resin, or polystyrene blend resin, polyacrylic resin, polystyrene resin, polyamide having affinity with these resins A series resin or the like may be used. The dry film thickness of the adhesive layer is 1
Generally, it is set to μm to 10 μm. The adhesive layer has translucency. This is because the design of the second decorative film 5 can be seen through from the first decorative film 4 side, and the design of the first decorative film 4 can be seen through from the second decorative film 5 side.

  A manufacturing method in the case where both the first mold 1 and the second mold 2 have sandwiching members will be described. That is, the first decorative film 4 is placed along the mold bottom of the first mold 1 using the molding simultaneous double-sided decorative mold having the sandwiching member between both the first mold 1 and the second mold 2 described above. The injection port side end 6 of the first decorative film 4 is sandwiched by the first sandwiching member 71, and the second decorative film 5 is placed along the mold bottom of the second mold 2 and the injection port of the second decorative film 5. The side end 6 is sandwiched by the second sandwiching member 72, the first mold 1 and the second mold 2 are closed, and the first mold 1 is sandwiched between the first decorative film 4 and the second decorative film 5. A molded resin is injected from the injection port 3 to mold a resin molded product, and at the same time, a decorative film is adhered to both the front and back surfaces of the resin molded product to obtain a molded simultaneous double-sided decorative product.

  More specifically, as shown in FIG. 4, the first mold 1 comprises a first mold 1 and a second mold 2, and the first mold 1 has a first fitting having an injection port 3 and a slope 13 for sandwiching the first film at the mold bottom. It has the 1st pinching member 71 which exhibits the shape which can be fitted to the 1st fitting recessed part 14 via the joint recessed part 14 and the 1st decoration film 4, and the 1st pinching member 71 is the air cylinder 10 via the rod 11.
