Place the single-layer solid wood board in the mold box 61, stack the cushion frame and the mold box 61 in sequence, and finally install the pressing plate 64, and connect all the mold boxes 61 and the pressing plate 64 with bolts; b. Place the pressing mold 6 on the lower plate 4, start the hydraulic cylinder 1 to press the pressing mold 6 down until the gap between the mold box 61, the cushion frame, and the pressing plate 64 is zero, tighten the bolts between all the mold boxes 61 and the pressing plate 64, and control the hydraulic cylinder 1 to rise and reset; c. Open the valve 66 connected to the high-pressure water source, and the high-pressure water will soak the single-layer solid wood board until it is saturated, and close it. Close the valve 66 connected to the high-pressure water source; d. After removing the cushion frame, restart the hydraulic cylinder 1 to press down the pressing mold 6 until the gap between the mold box 61 and the mold box 61 and the gap between the mold box 61 and the pressing plate 64 is zero, the solid wood board is compressed, and the moisture in the solid wood board is squeezed out. Tighten the bolts between the mold box 61 and the pressing plate 64, and control the hydraulic cylinder 1 to rise and reset; e. Start the valve 66 connected to the hot air source to dry the compressed solid wood, and close the valve 66 connected to the hot air source; f. Repeat steps c and e several times to force the shrinkage rate of each part of the wooden board to be uniform.

[0034] The device can be used to perform moisture-proof treatment on a single-layer solid wood board. By setting a pressing mold 6, and the thickness of the single-layer solid wood board is less than or equal to the depth of the inner cavity of the mold box 61 plus the thickness of the cushion frame, the single-layer solid wood board is placed in the pressing mold 6 for shaping and then soaked in water, the force of the wood board deformation is released to the inside of itself, and the shrinkage rate inside the wood board is uniform; then the wood board is compressed and dried to make its internal structure dense and improve its strength; and then soaked and dried several times to release the internal stress. A solid wood board with high strength and uniform internal shrinkage rate is obtained, and the complex processes of making thin boards, splicing, applying adhesives, and pressing are omitted, the cost is reduced, and it is more environmentally friendly without using adhesives. By setting the cushion frame, the shaping of the single-layer solid wood board by the pressing mold 6 can be realized. After removing the cushion frame, the solid wood board can be shaped when it is compressed. The treatment of the solid wood board can be completed by fixing it once, and there is no need to change the mold and repeatedly disassemble and assemble, which improves work efficiency.

[0035] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention.
