  In the invention according to claim 1 of the present application,It is only necessary to use an expensive hologram film when forming the mold, and it is not necessary to use the hologram film when forming the substrate with the mold. For this reason, consumption of an expensive hologram film is significantly reduced, and a complicated process of laminating a hologram film on the surface of a previously formed substrate can be omitted. Also,A hologram composed of fine irregularities is formed as the second surface state so as to be superimposed on at least a part of the first surface state having predetermined irregularities. As a result, the degree of freedom for setting the deflection direction of the incident light by the fine unevenness is remarkably increased as compared with the case where a hologram is simply formed on a smooth surface. For this reason, it becomes possible to form a hologram so that the said interference color is visually recognized over a wide angle range. Therefore, the visibility of the interference color on the surface subjected to the hologram processing is improved, and the design property is preferably improved.When producing a decorative molded product, the productivity is remarkably improved.

[0032]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
Hereinafter, a first embodiment in which the decorative molded product of the present invention is embodied in an automobile ornament will be described.
[0033]
First, the specific structure of the ornament of this Embodiment is demonstrated based on FIGS.
FIG. 1 shows a planar structure of the ornament according to the present embodiment, FIG. 2 shows an enlarged end surface structure along line 2-2 in FIG. 1, and FIG. 3 shows a design surface of the ornament. A part of the cross-sectional structure is shown enlarged.
[0034]
As shown in FIGS. 1 and 2, the ornament 10 of the present embodiment largely covers a base 11 formed of a transparent resin (for example, acrylic resin) and the entire back surface 12 of the base 11. And the coating layer 13 formed as described above.
[0035]
Hereinafter, the shape of the substrate 11 will be described in detail.
A recess 14 is formed on the back surface 12 of the substrate 11. A plurality of recesses 15 are formed in the inner bottom surface 14 a of the recess 14. With these recesses 15, a design character, for example, “TG” is engraved on the inner bottom surface 14 a of the recess 14. The inner bottom surface 14a and the plurality of recesses 15 constitute a third surface state having a rectangular cross section. The amplitude in the third surface state is set by the depth of the recess 15 with respect to the average height of the inner bottom surface 14a.
[0036]
Further, in the inner bottom surface 14a of the recess 14, a portion where the recess 15 is not formed is provided with irregularities having a predetermined amplitude on the surface thereof, whereby a first surface state that exhibits high designability A design surface 16 is formed. A plurality of embossed grooves 17 extending in the longitudinal direction of the ornament 10 (left and right direction in FIG. 1) are formed on the design surface 16 as the predetermined unevenness. In addition, as shown in FIG. 3, these embossed grooves 17 have a substantially V-shaped cross section, and are formed so that the inclination angles of the side surfaces are equal. The embossed grooves 17 are formed so that the opening width and depth thereof are not uniform. The amplitude on the design surface 16 is set by the difference in height between the maximum protrusion of the convex portion and the deepest portion of the concave portion in the embossed groove 17.
[0037]
Further, the entire surface of the embossed grooves 17, that is, the entire design surface 16 is subjected to hologram processing. In the present embodiment, as the hologram processing, the hologram 25 having the second surface state is formed on the design surface 16 by unevenness having an extremely fine amplitude compared to the amplitude of the design surface 16. It is formed so as to overlap. Further, a coating layer 13 is formed on the back surface 12 of the substrate 11 so as to cover the whole. In addition, this coating layer 13 is formed, for example with the vapor deposition film of a metal material, and serves also as the reflective layer which improves the reflective efficiency of the incident light which injects from the surface 11a of the base material 11. FIG.
[0038]
Hereinafter, the operation of the ornament 10 will be described.
In the ornament 10, a hologram 25 made of fine irregularities is formed on the design surface 16 on which a plurality of embossed grooves 17 are formed. Thereby, as compared with the case where the hologram 25 is simply formed on a smooth surface, the degree of freedom in setting the deflection direction of the incident light by the fine unevenness is remarkably increased. For this reason, the hologram 25 can be formed so that the interference color is visually recognized over the design surface 16 over a wide angle range.
[0039]
By the way, normally, in a decorative molded product in which a hologram is formed as in the ornament 10 in the present embodiment, the hologram is transferred by pressing a film on which a hologram processing has been performed on the surface of a previously formed substrate. It is formed. Alternatively, a hologram is formed on the surface of a base material formed in advance by attaching a film on which hologram processing has been applied.
[0040]
Each of these methods has a problem that the manufacturing cost increases because an expensive hologram film is used for each decorative molded product. In addition, since it is necessary to make the film adhere to a preformed substrate, it is difficult to process the surface having irregularities, which is troublesome.
[0041]
Therefore, in the present embodiment, the base material 11 is molded using a mold in which the hologram 25 is transferred and molded in advance, and then the coating layer 13 that covers the entire back surface 12 of the base material 11 is formed. The ornament 10 is manufactured.
[0042]
Hereinafter, the manufacturing procedure of such an ornament 10 will be described with reference to FIGS.
This ornament 10 is manufactured through the procedure described below, for example.
[0043]
"Mother formation"
First, the base 18 used for forming the mold cavity is formed (FIG. 4A).
"Wrinkle groove formation"
Next, a plurality of embossed grooves 17 extending in the longitudinal direction are formed on the surface which becomes the back surface 12 of the ornament 10 in the base body 18 (FIG. 4B). Specifically, the plurality of embossed grooves 17 are formed by cutting the surface of the base 18 using diamond cutting. In the present embodiment, a die 23 having a triangular cross-section at the tip is used for such cutting. Then, the depth to be cut by the die 23 is appropriately changed for each embossed groove 17. Accordingly, the embossed grooves 17 are formed so that the opening widths and depths thereof are not uniform.
[0044]
"Hologram formation"
Next, a hologram film 26 on which hologram processing has been applied in advance is brought into close contact and pressure-bonded over the entire surface of the base 18 where the plurality of embossed grooves 17 are formed, whereby the hologram 25 is transferred onto the base 18. (FIG. 4C).
[0045]
"Concavity formation"
Next, the design characters are engraved by forming a plurality of recesses 15 by cutting the surface on which the plurality of embossed grooves 17 and the hologram 25 are formed (FIG. 4D). .
[0046]
"Primary master formation"
Next, a primary master 19 which is a reverse type and a first reverse type of the base 18 subjected to the above-described various processes is formed by using a well-known electroforming technique (FIG. 5A). The primary master 19 is made of a metal such as nickel. For this reason, it is excellent in durability, and it is possible to accurately form a large number of inversion types based on the primary master 19.
[0047]
"Secondary master formation"
Next, a secondary master 20 as a second inversion type that is an inversion type of the primary master 19 is formed from the primary master 19 using a resin material or the like (FIG. 5B).
[0048]
"Mold formation"
Next, a mold 22 having a cavity 21 having a shape corresponding to the secondary master 20 is formed using the secondary master 20 (FIG. 5C).
[0049]
"Base material molding"
Then, the said base material 11 is shape | molded using this metal mold | die 22 (FIG.5 (d)). Thereby, the base material 11 on which the plurality of concave portions 15, the plurality of embossed grooves 17, and the hologram 25 formed in the base 18 are transfer-molded is formed.
[0050]
"Cover layer formation"
And the said coating layer 13 which consists of metal films etc. is formed in the back surface 12 whole of this base material 11 using methods, such as a vacuum evaporation method etc., for example. Thereby, the ornament 10 is completed.
[0051]
Hereinafter, the effect | action by manufacturing the ornament 10 by such a procedure is demonstrated.
In other words, the film 26 for forming the hologram 25 is also necessary for forming the mold 22. However, once the mold 22 is formed using the film 26, the trouble of transferring the hologram 25 to the individual base material 11 using the film 26 or attaching the hologram film 26 is omitted. Is done. Even when the hologram 25 is transferred and formed on a surface that is difficult to adhere to the entire surface of the film 26, such as a surface having irregularities (design surface 16 in the present embodiment), By transferring and forming the hologram 25, the hologram 25 is formed on the design surface 16 of each base material 11.
[0052]
Therefore, according to the present embodiment, the following effects can be obtained.
(1) In this ornament 10, a hologram 25 made of fine irregularities is formed on the design surface 16 on which a plurality of embossed grooves 17 are formed. Thereby, as compared with the case where the hologram 25 is simply formed on a smooth surface, the degree of freedom in setting the deflection direction of the incident light by the fine unevenness is remarkably increased. Therefore, the hologram 25 is formed so that the interference color is visually recognized over a wider angle range of the surface on which the hologram 25 is formed. Therefore, the visibility of the interference color on the surface on which the hologram processing is performed can be improved, and the design property can be preferably improved.
[0053]
(2) In this ornament 10, the plurality of embossed grooves 17 formed on the design surface 16 are formed with uneven opening widths and depths. Thereby, the freedom degree about the setting of the deflection direction of the incident light by the fine unevenness | corrugation which comprises the hologram 25 can be raised suitably.
[0054]
(3) In this ornament 10, a recess 14 is formed on the back surface 12 of the base material 11, and a plurality of recesses 15 are formed on the inner bottom surface 14 a of the recess 14. Then, by the recesses 15, characters are engraved on the inner bottom surface 14 a of the recess 14. Thereby, design property can be improved more suitably.
[0055]
(4) In the ornament 10, the coating layer 13 made of a metal film is formed on the back surface 12 of the base material 11 including the design surface 16 on which the hologram 25 is formed so as to cover the entire surface. For this reason, while the design surface 16 is protected by the coating layer 13, the coating layer 13 itself can exhibit a decorative effect. Further, the coating layer 13 efficiently reflects incident light incident from the surface 11 a of the base material 11 and improves the visibility of the hologram 25. And for these, the design property can further be improved.
[0056]
(5) In this ornament 10, the base material 11 is formed of a transparent material. For this reason, high designability can be exhibited on the surface opposite to the surface on which the coating layer 13 is formed.
[0057]
(6) In the ornament 10, relatively fine irregularities such as a textured groove 17 and a hologram 25 are formed on the design surface 16. The fine unevenness is generated when the resin constituting the base material 11 is cured, and also plays a role of making the sink marks that cause the appearance of the base material 11 to be inconspicuous.
[0058]
(7) In the above embodiment, the hologram 25 is transferred to the mother body 18 by pressing the hologram film 26 on the surface of the mother body 18 on which the plurality of embossed grooves 17 are formed. Thereafter, a mold 22 is formed using the base 18, and the base material 11 is molded by the mold 22. For this reason, the film 26 for forming the hologram 25 only needs to be used for forming the mold 22, and after forming the mold 22, it is necessary to use the film 26 when forming the individual base material 11. Absent. Further, even when the hologram 25 is formed on a surface on which the film 26 is difficult to adhere, such as the design surface 16, the hologram 25 is transferred and formed in advance on the base 18, thereby A hologram 25 can be formed on the design surface 16. Therefore, the consumption of the extremely expensive hologram film 26 and the trouble of forming the hologram 25 can be greatly reduced, and the productivity of the ornament 10 can be significantly improved.
[0059]
(8) In the above embodiment, the design characters are formed by the plurality of concave portions 15 carved on the surface of the base 18 on which the plurality of embossed grooves 17 and the hologram 25 are formed. Thereby, a design character can be made to stand up in the hologram 25, and the ornament 10 with a high design property which has a design character can be manufactured at low cost by mold forming.
[0060]
(9) In the above-described embodiment, after the primary master 19 having excellent durability, which is an inverted type of the base 18 subjected to various types of processing, is formed, the secondary master that is the inverted type of the primary master 19 is formed. 20 is formed, and a mold 22 is formed using the secondary master 20. For this reason, a large number of secondary masters 20 can be formed from the primary master 19 with high accuracy, and as a result, a large number of highly accurate molds 22 can be formed from the single base 18. Thereby, the productivity of the ornament 10 can be further improved, and mass production can be easily handled.
[0061]
(Second Embodiment)
In the following, a second embodiment embodying the present invention will be described with reference to FIGS. 6 and 7, focusing on the differences from the first embodiment.
[0062]
In FIGS. 6 and 7, the same components as those of the first embodiment shown in FIGS. 1 and 2 are denoted by the same reference numerals, and the following description will be repeated. Omitted.
[0063]
As shown in FIGS. 6 and 7, the ornament 30 of the present embodiment and the ornament 10 of the first embodiment are different in that the ornament 30 is curved in the longitudinal direction.
[0064]
And also about this ornament 30, after forming the base material 31 using the metal mold | die 22 by which the hologram 25 was transcription-transferred previously similarly to the ornament 10 of the said 1st Embodiment, the whole back surface 12 is coat | covered. The covering layer 13 to be formed is formed by a procedure.
[0065]
Manufacture of such a curved ornament 30 can be easily realized by slightly modifying the manufacturing procedure of the ornament 10 described in the first embodiment.
[0066]
Specifically, as in the first embodiment, after passing through the steps of “matrix formation”, “texture groove formation”, “hologram formation”, “concave formation”, and “primary master formation”, “Secondary master formation” is performed as follows.
[0067]
"Secondary master formation"
That is, first, the primary master 19 is plastically deformed so as to bend in the longitudinal direction. And the secondary master 20 which is the inversion type is formed from this plastically deformed primary master 19. Thereby, the secondary master 20 is formed in a curved shape. Since the primary master 19 is formed of a thin plate metal by electroforming, it can be easily deformed while holding the hologram 25.
[0068]
Thereafter, similarly to the first embodiment, the ornament 30 is completed through procedures such as “mold formation”, “base material molding”, and “coating layer formation”.
[0069]
Hereinafter, the effect | action by manufacturing the ornament 30 by such a procedure is demonstrated.
In the present embodiment, the mold 22 is formed using the curved primary master 19, and the base material 11 is molded using the mold 22. For this reason, the metal mold | die 22 used for shaping | molding of the curved-shaped base material 11 is formed, without using the preform | base_body 18 previously curvedly formed. That is, even when the curved ornament 30 is formed, the base 18 used for forming the mold 22 can be one that is not curved itself. For this reason, the pressing operation of the hologram film 26 to the base 18 is not complicated. Therefore, the curved ornament 30 can be easily formed by a simple method of deforming the primary master 19 formed prior to the formation of the mold 22.
[0070]
Therefore, according to the present embodiment, in addition to the effects described in the above (1) to (9), the following effects can be obtained.
(10) According to the present embodiment, the curved ornament 30 can be easily formed by a simple method of forming the mold 22 by deforming the primary master 19.
