Description

Square box structure wood pattern

Technical Field

The invention relates to the field of moulds, in particular to a square box structure wood mould.

Background

The traditional square box wood pattern is the same as a cylinder structure wood pattern, a pure wood is used as a framework, solid wood is superposed to be used as an outer edge working surface of the wood pattern, and the wood pattern ensures the rigidity of the wood pattern, but has the following defects: the solid wood stack of outer fringe can consume more timber, and timber stack can consume a large amount of man-hours with machine-shaping, because ligneous stack causes the faying face between the panel to increase and influence the drawing of patterns, and timber causes the timber moisture content to be difficult to the stable control because of the change of air humidity and causes the wood pattern to split or warp.

s2: uniformly stirring and dissolving silicon dioxide nanoparticles in aqueous glue, maintaining the temperature of the aqueous glue at 50-60 ℃, then placing the wood board and the brass plate in the aqueous glue, enabling the wood board to be positioned at two sides of the brass plate and tightly attached to the brass plate, clamping the brass plate and the wood board together by using the pressure of 50-60 Mpa, and applying the pressure for 20-25 min;

s3: and drying the glue by using 10-15 ℃ air flow, and polishing the glue smoothly.

This scheme adopts brass board, plank (can also be the compoboard for the wood), nanometer silica granule and water-based glue to prepare the multiply wood, for traditional three splint or five-ply board (three splint are the common type of multiply wood with five layers of boards), the intermediate layer that this scheme made not only has good elasticity, has intensity height moreover, difficult fracture, and has the hydrophobicity, can not absorb water the fracture, and application temperature range is wide, and it is little to be influenced by expend with heat and contract with cold.

The brass plate has good rigidity relative to the wood plate, and the brass plate is slightly affected by thermal expansion and cold contraction, so that the whole multilayer plate has higher hardness and is not easy to break by adopting the brass composite template relative to a pure wood plate structure.

Meanwhile, the brass plate and the wood plate are bonded together by using the water-based glue, and the characteristics of the water-based glue and the hydrophobicity of the nano silicon dioxide particles are utilized again, so that the whole multilayer plate is not easy to absorb water and deliquesce.

Optionally, the shape of the brass plate is consistent with that of the wood plate, the thickness of the brass plate is 3-4 mm, and the thickness of each wood plate is 5-10 mm.

Optionally, the mass ratio of the aqueous glue to the silicon dioxide nanometer is 300: 1.

optionally, the number of the wood boards is two, the two wood boards are respectively located on two sides of the brass plate, the thickness of the brass plate is 3mm, the thickness of the wood board is 10mm, and the thickness of the water-based glue is 0.2 mm.

Optionally, the oxygen volume of the gas stream is less than 15% and the humidity of the gas stream is less than 35%.

The oxygen content in the air flow is lower than 15 percent, so that the purpose is to ensure that the oxygen content in the solidified bubbles is low, and the low oxygen content in the bubbles can reduce the oxidation effect of the bubbles on the brass plate and the wood plate, and prolong the practical life of the whole multilayer plate. The humidity of the gas stream was less than 35% to allow rapid moisture wicking of the gas to dry the multilayer monolith.

Optionally, the speed of the airflow is 6-8 m/s.

The air speed blow-drying is used for ensuring that excessive burrs are not left on the surface of the glue while the glue is blow-dried, and convenience is provided for next polishing.

The wood board in this scheme can be the plank of making by the wood, also can be the plywood that saw-dust and glue mix made, also can be other composite sheets, the plank of preferred wood making in this scheme.

The invention has the beneficial effects that: for the wood, the multiply wood is more difficult to absorb water, can not ftracture during the use, and the precision is higher, and for the wood stack more convenient, practice thrift more.
