On the lower surface of the upper die 8 of the press machine 7, a fitting recess 9 that fits into the rod-like body 6 is formed. It is also possible to form a ridge on the lower surface of the upper die 8 and to form a groove on the upper surface of the rod-like body 6 to fit the ridge 8. The external dies 2 and 2 'are erected on the same base 33 shown in FIG.

The internal mold 1 is sandwiched between the external molds 2 and 2 '(a space for holding a molding container) so as to be detachable. External mold gussets (reinforcing plates) 11 and 11 ′ are fitted on the outside of the external molds 2 and 2 ′. Reinforcing plates 12 and 12 'having a triangular cross section are provided facing each other at the outer lower end of the gusset plates 11 and 11'.

The board 14 at the upper end of the lower mold 13 of the press machine 7 ′ is in pressure contact with the bottom surface of the molding container 1 during pressing, but when the inner mold 1 is detached from the outer molds 2 and 2 ′, As shown in FIG.

As shown in FIG. 1, the length of the external molds 2, 2 ′ is slightly smaller than the internal mold 1, and both ends of the internal mold 1 protrude from both ends of the external molds 2, 2 ′. As shown in FIGS. 3 and 4, the fixing devices 15 and 15 ′ are provided on the protruding portions 16 and 16 ′ of the internal mold 1 from the external molds 2 and 2 ′. Screw rods 25 are inserted into the through holes of the mold 1 and the rod-shaped body 6, nuts are screwed onto the screw rods protruding from the fixing device, and the rod-shaped body 6 and the molding presser pad 5 are pressed to add the bamboo material 4. The pressure state is maintained.

  The movable plates 3 and 3 'are plate-like, and the outer ridges 17 and 17' are formed in two steps on the outer side, and the ridges are fitted into the concave grooves on the inner surfaces of the outer molds 2 and 2 '. You can slide. In the above embodiment, the ridges 17 and 17 ′ are formed in a substantially triangular shape with a cross section expanding outward, and the concave grooves on the inner surfaces of the outer molds 2 and 2 ′ are concave in the same shape as the ridges. It is formed into a strip. However, this is not necessarily the case. In short, what is necessary is just to form so that it can fit and slide, and especially the shape of a protruding item | line and a concave item is not limited.

  As shown in FIGS. 3 and 4, the fixing devices 15 and 15 ′ include a lower fixing member 18 in which a square concave upper end is horizontally bent outward and an inverted dish-shaped lower end horizontally folded. It consists of a bent upper fixing member 19, and both bent portions (flange portions) 20, 21 are connected and fixed by bolts 22, 22, respectively.

  Through holes 23 and 24 are formed in the center of the bottom surface of the lower fixing member 18 and the center of the upper surface of the upper fixing member 19, and screw rods 25 are fitted into both through holes, and nuts are projected from the fixing member 19. 26 is screwed together.

  Through holes 27, 28, and 29 are formed in the bottom surface of the inner mold 1, the molding retainer pad 5, and the rod-like body 6. In order to pressurize the bamboo material and maintain the pressurized state, the upper fixing member 19 and the lower fixing member 18 are connected and tightened. Although the bamboo material 4 is positioned inside the screw rod, the molding presser pad 5 may be positioned inside the screw rod so that the screw rod is not inserted.

  As shown in FIG. 1, a frame 32 for accommodating the moving plates 3 and 3 ′ is provided on the base 31, and a wall body corresponding to the inner wall of the external molds 2 and 2 ′ is provided on the inner surface of the frame 32. A concave groove 30 ′ having the same shape as the inner wall of the outer mold 2, 2 ′ is also formed in the wall body. Of course, the groove 30 'may be formed directly on the inner surface of the frame 32.

  Since the concave groove 30 ′ of the wall body 32 is provided at substantially the same height as the concave groove 30 of the external molds 2, 2 ′, the movable plates 3, 3 ′ are moved from the external molds 2, 2 ′ to FIG. When it is necessary to insert it into the concave groove of the outer mold 2, 2 ', it is moved in the opposite direction. Thus, it can be easily fitted into the concave grooves of the external molds 2 and 2 '.

  Next, a method of using the bamboo material press molding apparatus of the present invention will be described. First, after the internal mold 1 is mounted on the external molds 2 and 2 ', the movable plates 3 and 3' are inserted into the external molds 2 and 2 'from one end of the external molds 2 and 2'. The raw bamboo material is usually in the form of a bamboo piece or bamboo yarn, but a bonding agent is attached to it.

  When the raw bamboo material to which the bonding agent is attached is installed in the internal mold 1, the bamboo material must be filled up to the position of the moving plates 3 and 3 '. When a presser (for example, a hydraulic pump) is activated, the presser pad 5 is pressurized via the rod 6. As the molding presser pad 5 moves downward, the bamboo material 4 constantly receives pressure, and the surface of the bamboo material 4 moves downward to reach a certain position (at that time, the upper surface of the bamboo material 4 is more than the surface of the internal mold). To reach the predetermined position below).

  Then, as shown in FIG. 1, fixing devices 15 and 15 ′ are attached to internal mold protrusions 16 and 16 ′ protruding from both ends of the external dies 2 and 2 ′, and bolts of both flanges 20 and 21 of the fixing device. By tightening 22 and the central screw rod 25, the rod-shaped body 6 and the internal mold 1 are fixed. This prevents the molded presser pad 5 and the rod-like body 6 from being pushed and moved by tension before the bamboo material bonding agent is completely solidified.

  Thereafter, the movable plates 3 and 3 ′ are moved, the internal mold 1 fixed by the fixing devices 15 and 15 ′ is lifted and taken out between the external molds 2 and 2 ′, and transferred to a hardness work place (heat treatment place). After the molded bamboo material is heated and hardened and stabilized, the flange bolts 22 and 22 'and the central screw rod 25 are removed, the fixing devices 15 and 15' are removed, and then the rod 6 and the molding presser are removed. Remove the pad 5 and take out the molded bamboo material plate.

Those skilled in the art can easily understand that the following modifications can be made based on the above-described embodiments.
1. The movable plates 3 and 3 ′ may not be fixed to the external molds 2 and 2 ′ by fitting. This is because it can be fixed even by its own weight.
2. The moving plates 3 and 3 'may be omitted.
3. The fixing of the upper fixing member 19 and the lower fixing member 18 of the fixing devices 15 and 15 ′ can be performed only by the bolt 22 of the flange or the central screw rod 25. Further, the central screw rod can be fixed by screwing only one of the upper fixing member and the lower fixing member, and the other can be fixed by a spike. If it does in this way, even if the screw rod 25 is tightened, the upper fixing member will not be separated from the spike.
4). Of course, the shape and size of the upper fixing member 19 and the lower fixing member 18 can be changed.
5. The number of the fixing devices 15 and 15 ′ can be changed as necessary.
