  The present invention relates to a method for insert-molding a cabinet of an electronic device such as a portable communication device and an electronic device such as a portable communication device having a cabinet covered with a leather cover.

  2. Description of the Related Art Conventionally, mobile communication devices, particularly mobile phones, have been widely spread not only for younger age groups but also for older age groups. And each manufacturer is not only equipped with various new functions, but also has a new idea on the appearance of the product. Appearance colors start from gray, white, and silver, and bright colors such as red, orange, blue, and yellow have emerged. And now, products with leather or synthetic leather attached are being born. Products with leather or synthetic leather attached are generally formed by insert molding when the cabinet is molded. In this case, leather or synthetic leather is attached to a mold in advance at the time of cabinet molding, and a molten resin is allowed to flow at the same time.

  Patent Document 1 inserts a print sheet on which a state display unit that displays an operation state of a panel on an operation panel of an electric device and a function display unit that represents an operation function is printed with resin, and uses an opening of the print sheet Thus, the positional accuracy of the coating printing of the matte ink layer and the solid ink layer is improved, and the positional deviation from the display window is prevented.

  However, as in Patent Document 1, in order to insert-mold a flat printed sheet, it is necessary to pay attention to the printing misalignment. However, when leather or synthetic leather is insert-molded into a cabinet having a curved surface, a flat shape is required. When the leather or synthetic leather is affixed to the curved surface portion, excess meat of the leather or synthetic leather protrudes, and there is a problem that wrinkles occur after molding and the appearance is poor.

  In order to improve this, even if a curved surface is formed on the leather or synthetic leather in advance by a press mold, the leather or synthetic leather cannot completely retain the curved surface and returns to a certain extent. Even if insert molding is performed in this state, wrinkles are generated on the curved surface of the corner.

  On the other hand, the above-described wrinkle can be prevented to some extent by the insert molding method of Patent Document 2, but if a decorative sheet with a textured leather wrinkle pattern is used to give a leather feel, In some cases, a gap is formed in the resin, resulting in insufficient adhesion to the synthetic resin.

  In addition, there is a problem in that the leather wrinkles of the decorative sheet are crushed by the molding pressure during insert molding, and the touch feel becomes hard.

  In view of the above-described problems, an object of the present invention is to insert-mold leather or synthetic leather while maintaining adhesion so that wrinkles are hardly formed, and to maintain a soft tactile sensation even in a curved cabinet.

  In order to achieve the above object, in the present invention, a leather cover in which leather or synthetic leather and a plastic sheet are bonded with a double-sided tape is insert-molded.

−Cabinet insert molding method−
Next, an insert molding method for the back cabinet 2a of the mobile phone 1 will be described.

  FIGS. 3 to 6 are views showing the order of manufacturing the synthetic leather cover 9 that covers the external appearance of the first housing 2.

  First, as shown in FIG. 3, the 1st double-sided tape 43 is affixed on the nonwoven fabric layer 42 side of the planar synthetic leather main body 30. The planar plastic sheet 21 is bonded to the first double-sided tape 43.

  Next, a second double-sided tape 44 is attached to the side of the plastic sheet 21 opposite to the synthetic leather body 30. This 2nd double-sided tape 44 is utilized for adhesion | attachment with the base material 20 at the time of insert molding. The surface of the second double-sided tape 44 is covered with a separator (not shown). In this way, the flat synthetic leather cover 9 is formed in advance.

  Next, as shown in FIGS. 4 and 5, the flat synthetic leather cover 9 of FIG. 3 is made to have the curved shape of the first housing 2 while applying temperature with a press molding machine (not shown). Provide irregularities on the surface. In addition, since the surface of the 2nd double-sided tape 44 is covered with the separator, the synthetic leather cover 9 does not stick to the press mold. At this time, the sub display portion recess 18 is recessed at a position corresponding to the sub display portion 7, and the speaker portion recess 19 is recessed at a position corresponding to the speaker sound emitting portion 8 (see a cross-sectional view taken along line XX). Also, the corner portion 23 is formed at the same time. In the molding of the corner portion 23, when only the synthetic leather main body 30 is press-molded, it is almost restored to the plane after being removed from the press-molding machine, and the effect of press molding is reduced. By pressing the plastic sheet 21 together, it is held in the form of a press mold. Further, since the plastic sheet 21 is molded while being softened by applying a temperature, the wrinkles are stretched and become inconspicuous from the appearance.

  Next, as shown in FIG. 6, the curved synthetic leather cover 9 of FIG. 5 is cut into the outer shape of the shape of the first housing 2 and necessary holes are punched out. Here, in making holes in the speaker sound emitting unit 8 and the sub display unit 7, holes are made along the recesses on the inner side of the recess side surfaces of the sub display unit recesses 18 and the speaker unit recesses 19. For this reason, the sub display portion hole 24 and the speaker portion hole 25 are formed so that the cut surface is bent so as to bend downward (see a cross-sectional view taken along the line YY). Thus, the cut surface around the hole is covered with the synthetic leather main body 30, so that it looks good.

  Next, as shown in FIG. 8, the synthetic leather cover 9 of FIG. 5 is attached so that the synthetic leather main body 30 side contacts the molding surface 32a of the lower mold 32 of the injection mold 31, and the separator of the second double-sided tape 44 is attached. Remove. The synthetic leather cover 9 is attached to the lower mold 32 through the sub display portion hole 24 and the speaker portion hole 25. Then, the upper mold 33 is closed to form the cavity 34. A molten resin is poured into the cavity 34 and insert molding is performed by injection molding. At this time, the second double-sided tape 44 is in close contact with the substrate 20. Further, due to the cushioning properties of the nonwoven fabrics 43a and 44a of the first and second double-sided tapes 43 and 44, the leather wrinkle pattern of the urethane layer 41 is not easily crushed by the pressure during molding. Thereby, the back side cabinet 2a of the 1st housing | casing 2 shown in FIG. 7 is completed (refer ZZ sectional drawing).

-Effect of the embodiment-
Therefore, according to the method of insert-molding the cabinet of the electronic device according to the present embodiment, when the synthetic leather main body 30 is insert-molded in the back-side cabinet 2a having a curved surface, the generation of wrinkles in the corner portion 23 is reduced, Since the appearance can be improved and the adhesion can be maintained, the synthetic leather main body 30 is hardly peeled off. Furthermore, the soft touch feeling of the surface of the synthetic leather main body 30 can be maintained by adhering with the first and second double-sided tapes 43 and 44 provided with the soft nonwoven fabrics 43a and 44a.
