る。That is, first, in the setup process, only the primary side is injection-molded and the rotary platen is rotated 180 degrees. In this primary side injection molding, the wood decorative board 1 is set in the primary side cavity 56. As shown in FIG. 4, the setting method is as follows. As shown in FIG. 4, the wood decorative board 1 is brought into contact with the fixed die 56a so that the surface thereof faces the cavity portion, and vacuum adsorption 56b is performed from the cavity portion side temporarily. It is done by stopping. At this time, when backing the protective plate, the protective plate coated with an adhesive is attached to the back surface of the wood decorative board 1.

変えて連続的に射出成形が出来るようになっている。After this, the mold clamping process is performed by the mold clamping cylinder 58,
Injection molding is performed simultaneously on the primary and secondary sides. In the primary side cavity 56, as shown in FIG. 4, a synthetic resin is injected from the primary side injection unit 51 through a gate pole 56d of a movable mold 56c, and a synthetic resin layer is formed on the back surface side of the wood decorative board 1. Form 2. At this time, when the protective plate is present, the step of adhering to the wood decorative plate 1 is performed at the same time. In the secondary side cavity 57, the transparent synthetic resin layer 3 is injection-molded on the surface of the wood decorative board 1. As a result, the position can be changed by the rotary platen 55 and injection molding can be continuously performed without removing the mold from the mold.

極薄の場合には、前記のように保護板を裏打ちすること
により十分な補強が可能である。In the composite component 4 thus formed, the wood decorative board 1 can be clearly seen through the transparent synthetic resin layer 3 on the surface, so that the wood decorative board can be finished in a realistic appearance and the back surface of the wood decorative board 1 can be finished. Since the synthetic resin layer 2 is provided, has a strong structure. When the wood decorative board 1 is extremely thin, sufficient protection can be achieved by lining the protective board as described above.
