There is known a wood decorative mold material obtained by covering the outer surface (b) of the metal mold material (a) with the wood plate material (c). In this case, the metal mold material (a) is an aluminum mold material having a rectangular hollow section, and the wood plate material (c) is attached only to one side surface portion of the outer surface (b) of the metal mold material (a). .
Further, the wooden board material (c) is formed by adhesively laminating a decorative board (e) made of a veneer on the surface of a substrate (d) made of plywood, and the back surface of the substrate (d) is made of a metal mold material (a). The wooden board (c) is attached by being fixedly adhered to the outer surface.

[0003]

However, in the above conventional technique, since the entire back surface of the substrate (d) of the wooden board (c) is adhered and fixed to the outer surface of the metal mold (a), it is made of metal. Due to the difference in expansion and contraction between different materials such as expansion and contraction due to temperature change of mold material (a) or moisture absorption of wood board material (c), expansion and contraction due to drying, bimetal phenomenon occurs between the two materials, and in the longitudinal direction It was prone to warping and bending.

The present invention has been invented to solve the above-mentioned problems in the prior art. That is, the problem is that the bimetal phenomenon between different materials is prevented, and warpage and bending deformation occur in the longitudinal direction. It is to provide a wooden decorative material that is difficult to make.

[0005]

A wood-made decorative mold material of the present invention comprises a metal mold material and a plurality of base plate pieces of equal thickness bonded and fixed to the outer surface of the metal mold material at intervals in the longitudinal direction of the mold material. A wood surface plate is attached to the surface of the base plate piece so as to span between the base plate pieces, and the outer surface of the metal mold is covered by the wood surface plate. The above problems have been solved.

[0006]

In the wood decorative mold material of the present invention, a plurality of base plate pieces of equal thickness are adhered and fixed to the outer surface of the metal mold material at intervals in the longitudinal direction of the mold material. Since the wood surface plate is attached to the surface of the base plate piece so as to bridge it, the difference in expansion and contraction in the longitudinal direction between the metal mold and the wood surface plate is absorbed in the space between the base plate pieces. The bimetal phenomenon does not occur between the two, and therefore warpage and bending deformation in the longitudinal direction are prevented.
