A mold supporting the is used. Each of the cavity molds 6.7 can be filled with molten resin using an injection nozzle 8.9, and the first cavity mold 6 has a finely uneven surface in order to draw a self-patterned line pattern on the decorative surface. 6a is formed on the cavity surface. In addition, each core type 3a,
3b, 3c, and 3d are equipped with an eject bin 10 for removing the decorative molded product 20 in the final step.

いるとよい。Using this injection mold, the base layer side and the surface layer side are laminated and molded using different synthetic resins. As for the synthetic resin, a colored opaque synthetic resin such as a mixture of polycarbonate resin and ABS resin is used for the base layer side, and decorativeness can be further improved by mixing a light-reflecting substance such as metal powder with this synthetic resin. can. Furthermore, a colorless or colored transparent or semitransparent synthetic resin such as methyl methacrylate resin can be used for the surface layer side. Each of the synthetic resins is filled into the cavity mold 6.7 from the injection nozzle 8.9 in a molten state, but in order to avoid mixing with each other during stacking, the synthetic resins that are injection molded first have a melting temperature of 250 to 270. It is preferable to use a synthetic resin having a melting temperature of about 230 to 240°C, which is relatively abrasive temperature, as the synthetic resin to be laminated and molded later.

Then, as shown in FIG. 2, a colored and opaque synthetic resin 21' is filled to form a base layer side 21 like that of the core mold 3b.

用する。One side of the base layer side 21 is shaped as a small uneven surface 21a with an uneven surface 6a on the inner surface of the cavity, and the other side has a fixing means 21b such as a boss for bearing a stud bolt or a fixing means 21b for attaching to the object to be attached. The fixture can be integrally molded. When the cavity mold 6 moves away from the mold after forming the base layer side 21, the base 2 rotates 90 degrees and moves upward in FIG. 1 like the core mold 3b while holding the base layer side 21 and stops. An identification member 22 formed into a relatively rigid sheet shape is temporarily fixed to the base layer side 21 as shown in FIG. As the identification member 22, a metal plate made of aluminum or stainless steel or a hard synthetic resin film or sheet cut into a desired shape can be used, or as shown in FIG. A printing unit 22b4 may be provided. Adhesive can be attached to the back surface for temporary fixing, and even if the uneven surface 21a is formed on one side of the base layer side 21 during this temporary fixing, the identification member 22 is relatively rigid. It can be formed as a flat identification pattern. After the identification member 22 is attached, the base 2 is rotated by 90 degrees, thereby moving to the right side in FIG. Face to face with 7. When the cavity mold 7 moves in close proximity to the core mold 3C and fills the space between it and the core mold 3C with a colored and transparent synthetic resin 23' from the injection nozzle 9, the synthetic resin 23' fills the irregularities of the base layer side 21. It can be formed as the surface layer side by extending the surface into the cavity space. When injecting this synthetic resin 23', in addition to using a material with a relatively low melting temperature as described above, the molten resin 23' is injected onto the uneven surface 21a of the base layer side 21.
It is preferable to fill the molten resin 23' through a gate 12 through which the molten resin flows upward from the sprue 11 located away from the cavity surface, as shown in FIG. 5, so as not to apply the injection pressure 23' directly. When the molten resin 23' moves in the cavity space so as to cover the upper side of the identification member 22, as shown in FIG. The uneven surface 21a of the identification member 22 is slightly deformed so as to be crushed, and the adhesive 22c of the identification member 22 is filled in the recesses to firmly adhere the identification member 22.

２３を積層成形することもできる。Instead of this, as shown in Figure 7, the first molding 2
1 is formed as a flat surface, and an identification pattern is formed flatly on the flat surface by the above-mentioned identification member 22, hot stamping, printing, etc., and then molten resin 23' is filled and the surface layer side is 23 can also be laminated.

できる。When the base 2 is further rotated by 90 degrees after forming the surface layer side 23, the eject pin 10 of the core mold 3d protrudes from the lower position in FIG. 1, so that the base layer side 21 and the surface layer side 23 are The identification member 22 is sandwich-molded between the base layer side 21 and the surface layer side 23, and the decorative molded product 20 can be removed from the core mold 3d.

付形で所定位置に平坦な枠部等を形成しなくてもよい。In the decorative molded product manufactured in this manner, the identification member 22 can be seen through from the surface layer side 23 as a flat identification pattern X exhibiting a different color tone from the base layer side 21, as shown in FIG. Cut-like line pattern x2
Even if the identification pattern X is drawn, the identification pattern X can be seen through flatly, so there is no need to form a flat frame portion or the like at a predetermined position by molding.
また、裏面側には第１０図で示すような表面側から目視

。In addition, a boss portion 21b that is not visible from the front side as shown in FIG. 10 can be integrally molded on the back side, so if the stud bolt 24 is fixed to the bearing, it can be attached as a mounting tool to the object to be attached. can. The mounting tool is formed as a rib in the shape of an inverted letter, T-shape, or box shape, and is used for fixing to the object to be attached by fitting a clip or the like to be attached to the object to be attached to this rib. can.

るだけでも足りる。In the above-described embodiment, the layers were laminated in the order of the base layer side 211 and the surface layer side 23, but this may be reversed. Also,
In the mold, the base 2 has four core molds 3a, 3b, 3c,
I equipped 3d, but it is enough to equip two of them on opposite sides of base 2.

とよい。Furthermore, although each of the core molds 3a, 3b, 3c, and 3d was formed by laminating the base layer side 211 and surface layer side 23 in the same mold, it was possible to transfer this to a different mold and integrally mold the base layer side 21 and the surface layer side 23. You can also do it. Further, even when the base layer side 21 and the surface layer side 23 are formed of materials having different melting temperatures, it is preferable to select the same or similar solubility parameters (SP values).
