Description

Hot press forming mould for wooden furniture

The utility model relates to a kind of hot pressing die of woodenware moulding, is a kind of hot pressing die that culled wood and wood chip once is pressed into the moulding woodenware specifically.

At present, wood working industry mainly adopts spontaneous growth timber.Because the wood grows cycle is long, the source is difficult for, and not only can not satisfy flourishing wood-processing industry, and the price order becomes expensive.Machining process such as wound is cut, cutter are adopted in the imitative woodenware processing that passes, and often produce blankings such as a large amount of culled woods, wood chip, waste wood sheet.For solving the utilization of this part waste material, people develop a kind of method of suppressing the wood chip flat board.This method adopts a kind of mould that is made of upper die and lower die, and the wood chip that will pulverize is stacked between the upper and lower mould, adds to be pressed into the wood chip flat board, and upper and lower surface pastes facing.This method is simple to operate, but its weak point is: (1) adopts the dull and stereotyped edge of the wood chip part of this mould compacting all can't cover, outside the wood chip material is exposed to, generally be coated with dead color paint and whitewash, not only not attractive in appearance, and also the edge part material is more loose, intensity, hardness is not high, and as easy as rolling off a log breaking fallen to consult, and reduced value of the product widely; (2) because the wood chip material is loose, if the compacting high density, high-intensity woodenware has only when the wood chip stacking height to be higher than counterdie groove 3--8 doubly.The wood chip of q.s promptly satisfies above-mentioned requirements but the employing existing mold can not be banked up between upper and lower mould, and the wood chip flat board relatively approaches and quality is loose so suppress; (3) it is better simply tabular to adopt this mould generally can only suppress, the product dullness.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of and can once be pressed into the complete closely parcel wood chip of the wooden thin slice of fineness, and is handsome in appearance, intensity hardness height, and can reach the hot pressing die of the moulding woodenware of adequate thickness.

The die assembly that experiment showed, the utility model can be finished above-mentioned purpose.

The utility model is to improve to form on the basis of the dull and stereotyped compacting tool set of existing wood chip.It is characterized in that being equipped with between patrix and counterdie mould in, middle mould pars intermedia has an open-work, and open-work internal diameter profile shape is identical with counterdie groove outer rim shape.The height of middle mould is higher than more than three times of counterdie depth of groove, and according to the thickness of institute's compacted products, middle mould height is higher than counterdie depth of groove 3--8 doubly.Between middle mould and counterdie, leave a gap.The external diameter profile of patrix is identical with middle mould internal diameter profile, and mould internal diameter in being slightly less than.The patrix height should be greater than middle mould height and counterdie depth of groove summation.

During use, the veneer that one or more layers is treated is put between Yu Zhongmo and the counterdie earlier, fills up wood chip then in middle mould, one or more layers veneer is covered on the middle mould again.Mould is installed on the operating position of hydraulic press, patrix and counterdie is given being heated to 100 ℃ earlier earlier--200 ℃, the hydraulic press operating pressure is 100kg/cm ²--200kg/cm ²In pressing process, patrix is extruded onto the counterdie groove with former veneer and the wood raw material that is arranged in mould.Because the restriction of middle mould is arranged, loose wood chip can be along diffusion all around, and simultaneously, wooden thin slice under the effect of HTHP plastic deformation takes place, and then hardened forming.In patrix passes its outer rim of mould and counterdie groove inner edge up and down two veneer thin slices extruding combines in same contact place, and its redundance is cut off at same contact place, thick wood raw material fully closely is wrapped among the veneer.Utilize this mould to suppress the defective that woodenware can be avoided the exposed wood chip in edge of existing wood chip flat board fully, one-shot forming.Woodiness touch is extremely strong, and is handsome in appearance, simple to operate.And owing to can contain the wood chip of q.s in the middle mould, can not spread, so it is big to suppress product density, the intensity height.Not only water-fast, anti-ly damage by worms and have excellent impact.Do not have simultaneously waste material in process of production and produce, help raw-material making full use of.
