Mode for Carrying Out the Invention

[0012] Embodiments of the present invention will be described below based on the accompanying drawings. In the description, left and right refer to left and right with reference to the vehicle occupant, and front and rear refer to front and rear with reference to the vehicle traveling direction. The form shown in the accompanying drawings is an example of the present invention, and the present invention is not limited to this form.

[0013] <Example> Referring to FIG. 1. The resin molded product 10 is, for example, a decorative part provided in front of the vehicle occupant and constituting a part of the dashboard.

[0014] Referring to FIG. 2. The resin molded product 10 includes two first resin parts 20 and 30 made of a transparent resin through which light passes, a second resin part 40 made of a transparent resin that is provided separately between these first resin parts 20 and 30 and is irradiated with the light guided to the first resin parts 20 and 30, and a resin support part 50 that integrally supports these first resin parts 20 and 30 and the second resin part 40.

[0015] Refer to Figure 3. Ink 15i (see Figure 2) is transferred to a portion of the back surface of the first resin parts 20 and 30, and to the entire back surface of the second resin part 40. In Figure 3, the areas to which ink 15i has been transferred are indicated by coloring.

[0016] Refer to Figure 1. The first resin parts 20 and 30 can be made of polycarbonate (PC) or acrylic resin (PMMA). The same material is used for the two first resin parts 20 and 30. The first resin parts 20 and 30 are provided along the long side of the second resin part 40.

[0017] Each of the first resin parts 20 and 30 is connected to a light source such as an LED at least at one end (in this embodiment, the left end in the drawing). Light emitted from the light source passes through the inside of the first resin parts 20 and 30, which are light guides, and is reflected toward the second resin part 40, and incident upon the second resin part 40.

[0018] Furthermore, the first resin parts 20 and 30 may have edges or the like formed on them to reflect light toward the second resin part 40. This allows the entire second resin part 40 to be illuminated more evenly.

[0019] One of the first resin parts 20 (the first resin part 20 on the upper side of the drawing) is formed in a generally straight shape. The other first resin part 30 (the first resin part 30 on the lower side of the drawing) has a shape that is gently curved in part. The first resin parts 20 and 30 are shaped to follow the outer edge of the second resin part 40.

[0020] Furthermore, the first resin parts 20 and 30 may have the same shape. Also, depending on the size and shape of the second resin part 40, there may be one first resin part 20 or three or more first resin parts 20 and 30.

[0021] Refer to Figure 2. Hereinafter, the back surfaces of the first resin parts 20 and 30 may be referred to as the first support surfaces 21 and 31 supported by the support part 50.

[0022] Refer to Figure 3. The first resin parts 20 and 30 must have at least a portion where the ink 15i (see Figure 2) has not been transferred. That is, the first resin parts 20 and 30 are parts that include a portion where it is necessary to prevent the ink 15i from being transferred. Of the first resin parts 20 and 30, the portion where the ink 15i has not been transferred is called the first resin part main body 22 and 32, and the portion where the ink 15i has been transferred is called the first resin part extension 23 and 33.

[0023] The first resin component main bodies 22 and 32 are formed in the area where the second resin component 40 is provided between them. On the other hand, the first resin component extensions 23 and 33 are formed in the area where the second resin component 40 is not provided between them. The first resin component extensions 23 and 33 extend from both ends of the respective first resin component main bodies 22 and 32.

[0024] Furthermore, the first resin parts 20 and 30 may consist only of the main body portions 22 and 32 of the first resin parts. In other words, the first resin parts 20 and 30 may be formed only of the parts to which the ink 15i has not been transferred. By forming parts of the first resin parts 20 and 30 that have not had the ink 15i transferred on them, the absorption of light incident on the first resin parts 20 and 30 by the ink is suppressed, allowing them to shine brightly over a greater distance from the light source.

[0025] Refer to Figure 2 as well. In the areas of the first support surfaces 21 and 31 where the ink 15i has not been transferred, the resin constituting the first resin parts 20 and 30 is exposed to the outside. The areas where the resin is exposed to the outside can also be described as areas where printing has not been applied.

[0026] Refer to Figure 1. The material of the second resin part 40 can be polycarbonate (PC) or acrylic resin (PMMA). The material of the second resin part 40 is the same as that of the first resin parts 20 and 30.

[0027] By spaced apart the first resin parts 20 and 30 and the second resin part 40, which are made of the same material, it is possible to suppress the fact that light is not sufficiently reflected and transmitted within the first resin parts 20 and 30, and that the light immediately enters the second resin part 40. This suppresses the loss of energy of the emitted light and allows the second resin part 40 to be efficiently illuminated from a distance away from the light source. The second resin part 40 is a roughly trapezoidal plate-shaped member with one side gently curved. The shape of the second resin part 40 does not have to be all straight or roughly trapezoidal.

[0028] Refer to Figure 2. The second resin part 40 is formed with a thinner outer edge portion 42 than the thickness of the general portion 41. The edge portion 42 is formed over the entire outer circumference of the general portion 41.

[0029] When light is incident on the second resin part 40 from the first resin parts 20 and 30, the patterns formed by the ink 15i transferred to the back surface are illuminated, thereby enhancing the aesthetic appeal.

[0030] Hereinafter, the back surface of the second resin part 40 may be referred to as the second support surface portion 43, which is supported by the support part 50.

[0031] Refer to Figure 3. The back surface (second support surface 43) of the second resin part 40 is printed over its entire surface.

[0032] Furthermore, the second resin part 40 may have patterns or other designs printed on it, in which case a portion of the back surface of the second resin part 40 may be exposed. In this regard, it can be said that at least a portion of the back surface of the second resin part 40 has an area where ink 15i (see Figure 2) has been transferred.

[0033] Refer to Figure 1. It is preferable to use a resin such as ABS resin for the material of the support component 50. The melting point of the ABS resin is preferably lower than the melting point of the resin used for the first resin components 20, 30 and the second resin component 40. The support component 50 is made of a colored resin that does not transmit light.

[0034] The support component 50 has a frame-shaped frame portion 51 provided along the back surface of the edge portion 42 of the second resin component 40, and a connecting portion 52 that extends from the frame portion 51 toward the first resin components 20 and 30 and connects the first resin components 20 and 30 with the second resin component 40. The connecting portion 52 is connected to the portion of the first resin components 20 and 30 where the second resin component 40 is not positioned between them. That is, the connecting portion 52 extends to the extensions 23 and 33 of the first resin components.

[0035] Refer to Figure 2. Since the connecting portion 52 of the support component 50 is formed lower than the frame portion 51, the first resin components 20 and 30 are also positioned lower than the second resin component 40. As a result, the light emitted from the first resin components 20 and 30 is mainly incident from the edge portion 42.

[0036] The support component 50 has ribs 53 extending from the back surface of the frame portion 51 so as to be spaced apart from the second resin component 40. The resin molded product 10 is attached to the vehicle body or the like via the ribs 53.

[0037] The resin molded product 10 described above is formed by injection molding. A resin mold for forming the resin molded product 10 and a method for manufacturing the resin molded product 10 will be described below.

[0038] Refer to Figure 4. First, the resin molding die 60 will be described. The resin molding die 60 includes a first fixed die 61 which is immovable, a movable die 62 which is vertically movable (displaceable in one direction) and horizontally rotatable relative to the first fixed die 61, a slide die 63 which is slidably mounted relative to the movable die 62, and clamp members 64, 64 for pressing the film 15 to which the ink 15i is attached onto the first fixed die 61.

[0039] Refer to Figure 5. The resin molding die 60 further includes a second fixed die 65, which is an immovable mold.

[0040] Refer to Figure 4. The first fixed mold 61 has a mounting portion 61a on which the film 15 is placed. The first fixed mold 61 may also have holes formed therein for adsorbing the film 15 to the mounting portion 61a.

[0041] Refer to Figure 5 as well. For example, the movable type 62 moves above the second fixed type 65 by rotating it from above the first fixed type 61. Furthermore, rotating the movable type 62 returns it to above the first fixed type 61.

[0042] There may be two movable types 62. In this case, the sliding types 63 are also provided to match each movable type 62. By providing the first fixed type 61 and the second fixed type 65 180° apart, and the two movable types 62 (and the sliding types 63 corresponding to each movable type 62) 180° apart, both the first fixed type 61 and the second fixed type 65 can be operated simultaneously.

[0043] Furthermore, there may be three or more movable types 62 (and sliding types 63 corresponding to each movable type 62). In addition, the movable types 62 may be configured to reciprocate linearly between the first fixed type 61 and the second fixed type 65, or three or more movable types 62 may be configured to pass through positions opposite the first fixed type 61 and the second fixed type 65, each of which has one movable type 62.

[0044] The second fixed mold 65 may be provided integrally with the first fixed mold 61, or it may be composed of a separate mold independent of the first fixed mold 61. In other words, the first fixed mold 61 and the second fixed mold 65 each only need to be capable of forming a cavity different from that of the movable mold 62, and they may be a single unit or separate parts.

[0045] Next, the manufacturing method for the resin molded product 10 (see Figure 1) will be described.

[0046] Refer to Figure 4. First, prepare the first fixed type 61, the movable type 62, the slide type 63, the film 15 to which the ink 15i is attached, the clamp members 64, 64, and the second fixed type 65 (see Figure 5) (preparation step).

[0047] Refer to Figure 6. Next, place the film 15 on the mounting section 61a of the first fixing mold 61 with the ink 15i attached side facing upwards, and fix the film 15 using the clamp members 64, 64 (film fixing step).

[0048] Refer to Figures 7A and 7B. By lowering the movable mold 62, the first fixed mold 61 and the movable mold 62 form a second cavity C2. Also, before forming the second cavity C2, the sliding mold 63 is slid toward the movable mold 62, and the first cavity C1 is formed by the movable mold 62 and the sliding mold 63. The process of forming these first cavity C1 and second cavity C2 is called the first cavity formation process.

[0049] The first cavity C1 may be formed before the film fixing process (see Figure 6). On the other hand, the second cavity C2 must be formed by aligning it with the first fixed mold 61 on which the film 15 is fixed.

[0050] Refer to Figure 8A. Molten resin is poured into the first cavity C1 and the second cavity C2 (first resin pouring step), and the resin poured into the first cavity C1 and the second cavity C2 is cured (first resin curing step). As the poured resin hardens, the first resin parts 20, 30 and the second resin part 40 can be obtained.

[0051] Refer to Figure 3 as well. Of the first resin parts 20 and 30, the main body portions 22 and 32 of the first resin parts are formed by the first cavity C1, and the extension portions 23 and 33 of the first resin parts are formed by the second cavity C2. On the other hand, the second resin part 40 is formed only by the second cavity C2.

[0052] Refer to Figure 8B. Once the resin has hardened, the movable mold 62 is raised while the slide mold 63 remains slid toward the movable mold 62 (movable mold and slide mold raising process). Since the ink 15i has been transferred to the second resin part 40, it moves away from the backing paper 15m and rises together with the movable mold 62.

[0053] The movable type 62 may be provided with retractable claws or the like (not shown) to hold the second resin part 40.

[0054] Refer to Figure 5. Next, the movable mold 62 and the sliding mold 63 are rotated (moved) above the second fixed mold 65 (resin part moving process).

[0055] Furthermore, if two movable type 62s and two sliding type 63s are provided, the other movable type 62 and sliding type 63 will move above the first fixed type 61 (see Figure 4).

[0056] Refer to Figures 9 and 10A. The movable mold 62 and the sliding mold 63 are lowered and aligned with the second fixed mold 65 to form the third cavity C3 (second cavity formation step).

[0057] Refer to Figure 10B. Molten resin is poured into the third cavity C3 (second resin pouring step), and the resin poured into the third cavity C3 is cured (second resin curing step). The support part 50 can be obtained through the second resin curing step, and the resin molded product 10 is completed.

[0058] Refer to Figure 11A. After the second resin curing process is complete, the slide mold 63 is retracted (slide mold retraction process), and the movable mold 62 and slide mold 63 are raised as shown in Figure 11B (movable mold retraction process). This allows the resin molded product 10 to be removed from the second fixed mold 65.

[0059] Alternatively, the resin molded product 10 may be moved to a specific location to retract the slide mold 63 and the movable mold 62.

[0060] The manufacturing technologies for the resin molded product 10 described above are summarized below.

[0061] Refer to Figure 7A. Firstly, the method for manufacturing a resin molded product includes a preparation step of preparing a first fixed mold 61 that is immovable, a movable mold 62 that is displaceable in one direction (up and down) relative to the first fixed mold 61, a sliding mold 63 that is slidable in a direction different from one direction relative to the movable mold 62, and a film 15 to which the ink 15i to be transferred is attached, and a film fixing step of fixing the film 15 to the first fixed mold 61 such that the surface to which the ink 15i is attached faces the movable mold 62.

[0062] Refer to Figure 7B. Furthermore, the process includes a first cavity forming step in which the slide mold 63 is slid to form a first cavity C1 with the movable mold 62 and the slide mold 63, and the movable mold 62 is aligned with the first fixed mold 61 on which the film 15 is fixed to form a second cavity C2 with the first fixed mold 61 and the movable mold 62.

[0063] Refer to Figure 8A. Furthermore, the process includes a first resin pouring step of pouring molten resin into a first cavity C1 and a second cavity C2, and a first resin curing step of curing the resin poured into the first cavity C1 and the second cavity C2 to obtain a first resin part 20 cured in the first cavity C1 and a second resin part 40 cured in the second cavity C2.

[0064] Refer to Figure 7B. In the first cavity formation step, the ink 15i faces only the second cavity C2.

[0065] The ink 15i faces only the second cavity C2, and not the first cavity C1. The ink 15i is not transferred to the first resin part 20 (first resin part body portions 22, 32) formed in the first cavity C1, and is transferred only to the area formed by the second cavity C2. Therefore, the first resin part 20, which includes areas where it is necessary to prevent the transfer of ink 15i, and the second resin part 40, which needs to be printed on at least a part of it, can be formed simultaneously. The resin molded product 10 (see Figure 1) can be manufactured in fewer steps.

[0066] Refer to Figure 10B. Secondly, a method for manufacturing a first resin molded product, comprising: a preparation step in which a second immovable fixed mold 65 separate from the first fixed mold 61 (see Figure 4) is prepared, a resin component moving step in which the movable mold 62 and the sliding mold 63 are moved to a position facing the second fixed mold 65 while holding the first resin component 20 and the second resin component 40; a second cavity forming step in which the movable mold 62, which has been moved to the second fixed mold 65, is aligned with the second fixed mold 65 to form a third cavity C3; a second resin pouring step in which molten resin is poured into the third cavity C3; and a second resin curing step in which the resin poured into the third cavity C3 is cured to obtain a support component 50 that supports the first resin component 20 and the second resin component 40.

[0067] Since the first resin part 20 and the second resin part 40 can be formed simultaneously, they can be moved together to the second fixed mold 65 and supported and connected by the support part 50. Compared to the case where the first resin part 20 and the second resin part 40 are moved separately to the second fixed mold 65 to form the support part 50, the resin molded product 10 (see Figure 1) can be manufactured in fewer steps.

[0068] Refer to Figure 7B. Thirdly, the resin mold 60 includes a first fixed mold 61 that is immovable, a movable mold 62 that is displaceable in one direction relative to the first fixed mold 61, and a sliding mold 63 that is slidable in a direction different from one direction relative to the movable mold 62. The first fixed mold 61 has a mounting portion 61a on which the film 15 with the ink 15i attached is placed. By sliding the sliding mold 63, it is possible to pour resin between the movable mold 62 and the sliding mold 63, and when the poured resin hardens, a first cavity C1 is formed which will become the first resin part 20 (see Figure 8A). By aligning the movable mold 62 with the first fixed mold 61, it is possible to pour resin into the area facing the mounting portion 61a, and when the poured resin hardens, a second cavity C2 is formed which will become the second resin part 40.

[0069] The ink 15i can be directed only to the second cavity C2, and not to the first cavity C1. The ink 15i is not transferred to the first resin part 20 (first resin part body parts 22, 32, see Figure 8A) formed in the first cavity C1, and is transferred only to the area formed by the second cavity C2. Therefore, the first resin part 20, which includes areas where it is necessary to prevent the transfer of ink 15i, and the second resin part 40 (see Figure 8A), which needs to be printed on at least a part of it, can be formed simultaneously. By using the resin mold 60, the resin molded product 10 (see Figure 1) can be manufactured in fewer steps.

[0070] Refer to Figure 10A. Fourth, the third resin mold 60 further includes a second immovable fixed mold 65 separate from the first fixed mold 61 (see Figure 7B). By combining the movable mold 62, on which the first resin part 20 and the second resin part 40 are formed, with the second fixed mold 65, it is possible to pour in resin, and as the poured resin hardens, a third cavity C3 is formed which becomes a support part 50 that supports the first resin part 20 and the second resin part 40.

[0071] Since the first resin part 20 and the second resin part 40 can be formed simultaneously, they can be moved together to the second fixed mold 65 and supported and connected by the support part 50. Compared to the case where the first resin part 20 and the second resin part 40 are moved separately to the second fixed mold 65 to form the support part 50, the resin molded product 10 (see Figure 1) can be manufactured in fewer steps. By using the resin molding die 60, the resin molded product 10 (see Figure 1) can be manufactured in fewer steps.

[0072] Refer to Figure 2. Fifth, the resin molded product 10 includes first resin parts 20 and 30 which are made of resin, a second resin part 40 which is made of resin and is spaced apart from the first resin parts 20 and 30, and a support part 50 which integrally supports the first resin parts 20 and 30 and the second resin part 40. When the surfaces of the first resin parts 20 and 30 facing the support part 50 are designated as first support surfaces 21 and 31, and the surface of the second resin part 40 facing the support part 50 is designated as the second support surface 43, at least a portion of the first support surfaces 21 and 31 has the resin constituting the first resin parts 20 and 30 exposed to the outside, and at least a portion of the second support surface 43 has printing applied to it.

[0073] Because at least a portion of the first support surfaces 21 and 31 exposes the resin constituting the first resin parts 20 and 30 to the outside, it is possible to suppress the absorption of light reflected from within the first resin parts 20 and 30 by the printed ink 15i, allowing the product to illuminate further from the light source. Furthermore, the second support surface 43 is printed on its entire surface. If the first resin parts 20 and 30 and the second resin part 40 were formed individually and then printed after being attached to the support part 50, it would not be possible to print on the entire second support surface 43. However, because the first resin parts 20 and 30 and the second resin part 40 are molded simultaneously and the support part 50 is integrally formed as a resin molded product 10, it is possible to print on the entire second support surface 43. With the resin molded product 10 manufactured in this way, the resin molded product 10 can be manufactured in fewer steps.

[0074] Although the manufacturing technology for resin molded products according to the present invention has been described using a component used in a vehicle's dashboard as an example, it is applicable to other parts of the vehicle interior and to resin molded products other than those for vehicle use, and is not limited to these types. In other words, the present invention is not limited to the examples, as long as it achieves the function and effect of the present invention. [Industrial applicability]
