A kind of heat pressing forming machines for wood flour making sheet
Technical field
The present invention relates to a kind of heat pressing forming machines for wood flour making sheet, belong to compressing technical field.
Background technology
At present, top-grade furniture and high-grade household are decorate all based on the selection of wood materials, but continually developing along with the forest reserves, wood raw material seems day by day well sold and in short supply and makes wood raw material price constantly rise;Then people are while exploitation alternative materials, also in the recycling constantly studying waste wood, as wood flour material is made sheet material or shelves material etc.;But how tiny wood flour material is made available sheet material or shelves material, current people it is conceivable that can only be compressing method, but existing moulding press is due to the reason of mould, it is clear that it cannot bring making sheet for wood flour material simply and work;The wherein preparation of of paramount importance mould.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, and provide a kind of by existing hot press is improved, simple in construction, easy to use and reliable, it is possible to suitable in wood flour making sheet, and make the plate intensity produced big, Heavy Weight, it is simple to the heat pressing forming machines of woodworking machinery processing.
It is an object of the invention to complete by following technical solution, a kind of heat pressing forming machines for wood flour making sheet, it includes one with the gate frame of entablature, is provided with a block base in the middle of the bottom of frame, and submounts is configured with under one piece heating hollow sheeting;Described entablature is at least vertically installed with a hydraulic cylinder, and the hydraulic piston of hydraulic jacking cylinder is connected to below one the mould seat of honour with upper heating hollow sheeting, the top peripheral at described lower heating hollow sheeting is equipped with that a square is framed and being formed over by the framed die cavity enclosed of square at lower heating hollow sheeting;This die cavity is corresponding with the upper heating hollow sheeting of top, and is subject at the mould seat of honour after the effect of hydraulic jacking cylinder moves down, and upper heating hollow sheeting can synchronize to move down and be embedded in described die cavity.
Described gate frame is by four columns and is fixedly installed on the entablature on column and sill forms, and described entablature is provided with uniform two hydraulic jacking cylinder;Described square is framed by being circumscribed with a guide holder with vertically-guided hole in the middle of four corners or four limits respectively, and in described pilot hole, it is inserted with the lead being fixed on frame or base, and be also equipped with respectively on lead and support the pressure-bearing spring that square is framed;The hollow cavity of described upper heating hollow sheeting and lower heating hollow sheeting is provided with steam channel or is provided with steam circulation duct, and the two ends of described steam channel or steam circulation duct are respectively communicated with the vapour source in peripheral hardware.
Described entablature and sill are fixed on four columns respectively through the leghole of four arms of angle, described base is fixed on the centre of sill, the centre of sill is provided with under at least one and pushes up compressing cylinder, and this lower top compressing cylinder is connected to the base of top by respective hydraulic piston;Described square is framed to be fixedly mounted on the sill constituting frame by four leads.
The present invention has simple in construction, easy to use and reliable, it is possible to suitable in wood flour making sheet, and makes the plate intensity produced big, Heavy Weight, it is simple to the features such as woodworking machinery processing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: Fig. 1, shown in 2, heat pressing forming machines of the present invention, it includes one with the gate frame of entablature 1, is provided with a block base 2 in the middle of the bottom of frame, is configured with under one piece heating hollow sheeting 3 above base 2;Described entablature 1 is at least vertically installed with a hydraulic jacking cylinder 4, and the hydraulic piston 5 of hydraulic jacking cylinder 4 is connected to below one the mould seat of honour 7 with upper heating hollow sheeting 6, the top peripheral at described lower heating hollow sheeting 3 is equipped with a square framed 8 and is formed over, at lower heating hollow sheeting 3, the die cavity 9 enclosed by square framed 8;This die cavity 9 is corresponding with the upper heating hollow sheeting 6 of top, and is subject at the mould seat of honour 7 after the effect of hydraulic jacking cylinder 4 moves down, and upper heating hollow sheeting 6 can synchronize to move down and be embedded in described die cavity 9.
Shown in figure, gate frame of the present invention is by four columns 10 and is fixedly installed on the entablature 1 on column and sill 11 forms, and described entablature 1 is provided with uniform two hydraulic jacking cylinder 4;Described square framed 8 is by being circumscribed with a guide holder 12 with vertically-guided hole respectively in the middle of four corners or four limits, and in described pilot hole, it is inserted with the lead 13 being fixed on frame or base, and on lead 13, also it is equipped with the pressure-bearing spring 14 supporting square framed 8 respectively;The hollow cavity of described upper heating hollow sheeting 6 and lower heating hollow sheeting 3 is provided with steam channel 15 or is provided with steam circulation duct, and described steam channel 15 or the two ends of steam circulation duct are respectively communicated with the vapour source in peripheral hardware.
Entablature 1 of the present invention and sill 11 are fixed on four columns 10 respectively through the leghole of four arms of angle, described base 2 is fixed on the centre above sill 11, the centre of sill 11 is provided with at least one lower top compressing cylinder 16, and this lower top compressing cylinder 16 is connected to the base 2 of top by hydraulic piston;Described square framed 8 is fixedly mounted on the sill 11 constituting frame by four leads 13.
During use, first promote hydraulic jacking cylinder 4, upper heating hollow sheeting 6 will remove die cavity 9, then pouring in die cavity 9 by the wood flour after mix and blend according to a certain amount of, at this moment move in die cavity again through hydraulic jacking cylinder 4 by upper heating hollow sheeting 6, direct pressing is mixed with the wood flour of binding agent, upper heating hollow sheeting 6 and lower heating hollow sheeting 3 pass into steam simultaneously and are heated, and heat hollow sheetings by upper and lower two pieces the wood flour in middle die cavity is heated pressurization, and after keeping the regular hour, the demoulding.Described lower top compressing cylinder 16 plays demoulding effect, namely after upper heating hollow sheeting 6 removes die cavity, lower heating hollow sheeting 3 under the effect of lower top compressing cylinder 16 on move, along with the sawdust board of molding in die cavity is ejected from die cavity.
Stripping means of the present invention can have multiple selective, including existing arbitrary stripping means, it is also possible to the alternative structure being arranged to framed for square 8 to move up and down, in order to realize the demoulding.
