Abstract
A wood-plastic cladding co-extrusion die comprises a co-extrusion flow channel, and inserts for adjusting the shape of the co-extrusion flow channel are arranged at bypass flow parts of the co-extrusion flow channel and fixed in the co-extrusion flow channel through pin shafts. Through the installation of the inserts in the co-extrusion flow channel, when pressure in the co-extrusion flow channel changes, the inserts can automatically oscillate at different angles to adjust the size and shape of the co-extrusion flow channel in time, thereby achieving relatively accurate and easy pressure adjustment, setting a reasonable flow channel structure for co-extrusion production, increasing local pressure at confluence parts, eliminating confluence traces, improving work efficiency and reducing production cost.
Description
Technical field
The utility model relates to a kind of mould, and particularly a kind of wood is moulded and coated coextrusion mold mouth mould.
Background technology
In the prior art, it all is by virtue of experience that wood is moulded the design that coats the co-extruding flow channel in the coextrusion mold mouth mould, roughly sets a size; In equipment debugging, often need repetition test like this, repeatedly processing; Thereby waste a large amount of manpower and materials, and final effect is also not necessarily desirable.
Summary of the invention
The utility model technical problem to be solved is the deficiency to prior art, provides a kind of wood easy to use, reasonable in design to mould and coats coextrusion mold mouth mould.
The utility model technical problem to be solved is to realize through following technical scheme.The utility model is that a kind of wood is moulded coating coextrusion mold mouth mould, comprises co-extruding flow channel, and be characterized in: shunting place of described co-extruding flow channel is provided with regulates inserting of co-extruding flow channel shape, and inserting is fixed in the co-extruding flow channel through bearing pin.
The utility model technical problem to be solved can also further realize through following technical scheme, and that inserts is shaped as cam-like.
Compared with prior art; The utility model is inserted through in co-extruding flow channel, installing, and when pressure changed during co-extrusion flowed, swings different angles voluntarily through what insert; The size and the shape of in good time adjustment co-extruding flow channel; Make pressure adjustment relatively accurate, easy, can set out the flow passage structure that rational co-extrusion is produced, reach the local pressure that increases river outlet, eliminate the vestige that confluxes.Improve operating efficiency simultaneously, reduced production cost.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is a kind of structural representation of inserting.
The specific embodiment
Following with reference to accompanying drawing, further describe the concrete technical scheme of the utility model, so that those skilled in the art understands the present invention further, and do not constitute restriction to its right.
Insert 1 in time adjust co-extruding flow channel 2 shape, change the physical dimension of co-extruding flow channel 2, can be in control and adjustment material extrusion process the fluid pressure of control co-extruding flow channel 2 coextruded layers; If the fluid pressure that coextruded layer pressure is extruded than major ingredient is big, the thickness of coextruded layer is too thick so, and material cost is too high; If the pressure of coextruded layer is too little; Cause the coextruded layer layering, discharging can not coat the major ingredient surface fully, forms substandard products.Through adjusting insert 1 increase river outlet vertical local pressure, guarantee that coextruded layer can vertically mix at meet to eliminate the interflow vestige of coextruded layer.
Claims (2)
1. a wood is moulded and coated coextrusion mold mouth mould, comprises co-extruding flow channel, it is characterized in that: shunting place of described co-extruding flow channel is provided with regulates inserting of co-extruding flow channel shape, and inserting is fixed in the co-extruding flow channel through bearing pin.
2. wood according to claim 1 is moulded and coated coextrusion mold mouth mould, it is characterized in that: that inserts is shaped as cam-like.
