Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an inlaid decorative board and a blade mold used therein.

Decorative plates are being used in a wide range of applications, including furniture, buildings, vehicles, aircraft, musical instruments, stationery, and leisure goods.

Among the above-mentioned applications, decorative plates with inlays are used especially in high-grade products.

Conventionally, such decorative plates have been manufactured by hollowing out a base plate, inserting an inlay therein, and cutting off the protruding parts of the surface to make it flat. However, in recent years, in order to streamline the manufacturing process, a veneer with a different pattern cut into an appropriate shape is placed on top of the veneer, which has been combined with a base plate, using an adhesive, and then pressed and fixed to form an inlaid shape. are being gradually adopted.

According to the manufacturing method described above, the veneer to be used as the inlay is cut into the desired shape in a separate process, and the cut material is then placed by hand at the predetermined locations of the veneer, which is combined with the base plate. The veneer on the base plate and the cut veneer for the inlay must be attached using adhesive even if the veneer is placed in the correct place. When pressing, there is a risk that the cut veneer for the inlay may rub, and if this happens, the balance of the overall pattern, that is, the composition and arrangement, will be disrupted, and in any case, no defective products will be produced. It was very difficult to manufacture ornaments with inlays without them. The present invention aims to eliminate the above-mentioned drawbacks all at once.

In the present invention, adhesive is applied to the surface of the base plate, veneers are layered, and the veneer for inlay is temporarily fixed to the upper surface of the veneer using an adhesive having an appropriate adhesive force, and an inlay is formed using a blade shape. To provide a method for manufacturing a decorative board having an inlay, which is characterized by cutting, molding, and pressing into a desired shape while pressing the part, and a metal annular shape having a substantially rectangular vertical section and having a momme shape at the bottom. The object of the present invention is to provide a blade mold for use in manufacturing a decorative board, characterized by comprising a body and an elastic foam of rubber or plastic fitted into the annular body.

Since the blade mold used in the present invention has a rubber or plastic elastic body fitted into the cavity, the inlay veneer temporarily fixed on the veneer on the base plate surface can be pressed with the blade mold. When cutting and molding into an inlaid shape, the inlaid part is pressed by the elastic body in the cavity of the blade mold and changes from a temporarily fixed state to a state close to fixed, while parts other than the inlaid part remain in a temporarily fixed state because they are not pressed.

In order to change the inlaid part from a temporary state to a state close to a fixed state by pressing, the elastic material fitted into the cavity of the blade mold is usually a foam material with a hardness of 20 (measured with an Asker hardness tester). ) or more is sufficient.

As can be understood from the above, the adhesive used between the veneer on the base plate and the inlay veneer can be easily peeled off with your fingers in the areas where it is not pressed, and it can be easily removed with your fingers when pressed with the elastic body. The adhesive must be strong enough to almost stick to the attached parts. According to the manufacturing method of the present invention, if the base plate is placed at a predetermined position on the lower plate of the press machine, and one or more momme molds having an inlaid shape are fixed at predetermined positions on the upper plate of the press machine, the base plate can be placed on the base plate. When placing an inlay plate larger than the momme type on the veneer surface of the veneer, it is only necessary to place it under the blade type, and the inlay is then automatically cut and typed by a press machine, and the inlay is pressed. It is fixed at a predetermined location according to the arrangement of the momme mold fixed to the machine board, and there is no need to cut the inlay at a separate location and carry it by hand to the predetermined location as in the conventional manufacturing method. No special care or effort is required during the work, and a decorative board that does not disturb the balance as a whole is reliably obtained, and no defective products are produced.

Example As shown in Figure 1, clay 3 is placed on the base plate 1 of the breath board.
Apply 70 g of 50 centipoise vulcanized foamed polyurethane liquid (Toho Kagaku Hicel 0H) 2, layer it with a veneer (Makore) 3, and press for 3 minutes at a pressing pressure of 50 g I in a press machine with a hot plate temperature of 110°C. Breathe.

Next, as shown in Fig. 2, an inlay veneer (Rikirin) 5 is placed on the veneer 3 via a double-sided adhesive tape (Nitto Electric Industrial Knit Tape No. 54O3) 4 with the release paper removed. Temporarily fasten. As shown in FIG. 3, a polyethylene sponge 7 with a hardness of 27 mm (as measured by an Asker hardness tester) and a foaming ratio of 3.0 times is fitted into the hollow part 6 using a momme mold 8, as shown in FIG. 4. The inlay veneer 5 is press molded 9, the portion 11 other than the shape of the inlay 10 is removed, and the hot plate temperature is 110~
The inlay 10 was pressed for 1 minute at a pressure of 40 kgIcT1 in a press machine at 120°C.
A decorative board 12 having the following was obtained.
