Abstract
The invention discloses a supercharge mixed flow perforated plate for a wood plastic profiled bar extrusion mold. The perforated plate is a circular plate (1) in which a plurality of circles of concentric rings are formed; the center of the circular plate (1) is fixedly connected with a spindle-shaped mixed flow hammer (2) perpendicular to the plate surface; and the two ends of the mixed flow hammer (2) are conical, wherein one end is inlayed in the through hole in the circular plate. By adopting the supercharge mixed flow perforated plate, the smoothness of the large face of the sectional bar and the simulation degree of wood grain shape are effectively enhanced, and the physical property and surface quality of the sectional bar are improved.
Description
Technical field
The present invention relates to wood and mould the transition apparatus that the extruder of profiled bar extrusion die is connected with mould interface, is exactly the mixed flow porous plate for supercharging.
Background technology
Plastic extruding forming field, plastic extruding forming machine mainly contains extruder, extrusion die, stock mould, water tank and hauling machine.In extrusion molding process, the Main Function of die head, makes material further plasticizing in die head exactly, makes it to have rheological characteristic, produces necessary pressure, guarantees that goods are closely knit.The molten base of shaped article section configuration, molten base surrounding is answered uniformity, makes its internal stress little.Porous plate is exactly a transition apparatus of material and die head, is called again constant-current stabilizer.Its effect is as follows: 1, increase extrusion pressure, further plasticizing material stream; 2, the impurity not plastified in can filter material; 3, make the material of the screw of extruding from extruder become rectilinear motion.Better because of conventional plastic material mobility, after filtering out impurity, can well complete even plasticizing and then steady production.But wood plastic product is the mixture of wood powder and resin, it has following characteristics: 1, wood powder has stronger water imbibition, and polarity is very strong, plastics are nonpolar, have hydrophobicity, compatibility is very poor between the two, and interfacial adhesion is also very little, compared with other packing material, it is more difficult with mixing of resin matrix.2, hydrophilic wood-fibred has intermeshing tendency, but and between hydrophobic polymer, does not have a this tendency.Therefore wood-fibred is easy to produce when the less charge door by most of process equipments again and piles up, and polymer is easy to add in extruder.It is uneven that this not only causes wood-fibred to disperse in resin matrix, and sometimes also can cause windrow, stops up extruder.For addressing the above problem, conventional technical scheme is to increase transition apparatus, i.e. porous plate at material and die head at present.Though the impurity of conventional porous plate in can filter material, also make wood plastic product material become rectilinear motion from screw, but the mixing that wood is moulded and plasticizing effect is little desirable, the section bar of extruding like this may not reach the requirement of Wood-plastic profiles in outward appearance.Therefore for evenly reinforced, feed rate must be controlled, and the obstruction in reinforced process will be prevented.Greatly reduce production efficiency.
Summary of the invention
Object of the present invention be exactly solve porous plate between material and die head due to gloomy mould mix and plasticizing effect undesirable, wood is moulded the mixing lack of homogeneity of material, material flowing pressure is low, can not improve smoothness and the wood grain shape fidelity of large of section bar, physical property and the surface quality of section bar do not reach appearance requirement simultaneously, affect the problem of production efficiency.
For addressing the above problem, the technical solution used in the present invention is: mould profiled bar extrusion die supercharging mixed flow porous plate for wood, this porous plate is circular slab, on circular slab, offer the concentric annular distance of some circles, the center that it is characterized in that described circular slab is fixed with the spindle like mixed flow hammer vertical with plate face, the two ends of mixed flow hammer are taper, and one end is embedded in the interior middle inner via hole of circular slab.
For reaching better effect, described mixed flow hammer middle part is cylinder, and diameter is less than tapered cross-section, two ends maximum gauge, and cylinder is connected with junction, two ends arc-shaped transition.
For further increasing effect, above-mentioned mixed flow hammer is greater than other end maximum cross-section diameter away from circular slab end maximum cross-section diameter.
Further improve, described mixed flow hammer is involute away from sideline, circular slab end longitudinal section.
Beneficial effect of the present invention is: the mixed flow hammer protruding by increasing feed end, by adjusting the extrusion pressure of the large inner material stream of its size or increasing length, the built-in end of mixed flow hammer is for increasing pressure, the other end can play further mixed flow effect, quote colored shape material simultaneously and flow through the mixing uniformity of crossing moulding and strengthen material stream, thereby effectively improve smoothness and the wood grain shape fidelity of large of section bar, and improved physical property and the surface quality of section bar.

The specific embodiment
As shown in Figure 1, mould profiled bar extrusion die supercharging mixed flow porous plate for wood, this porous plate is circular slab 1, on circular slab 1, offer the concentric annular distance of some circles, aperture, the front and back place of each annular distance is inner small and outside big taper hole, as shown in Figure 2, the center of circular slab 1 is fixed with the spindle like mixed flow hammer 2 vertical with plate face, the two ends of mixed flow hammer 2 are taper, and one end is embedded in the interior middle inner via hole of circular slab, and this end being embedded in circular slab plays pressurization to the material by side.It is cylinder that mixed flow is hammered 2 middle parts into shape, and diameter is less than tapered cross-section, two ends maximum gauge, and cylinder is connected with junction, two ends arc-shaped transition.Mixed flow hammer 2 is greater than other end maximum cross-section diameter away from circular slab end maximum cross-section diameter.Mixed flow hammer 2 is involute away from sideline, circular slab end longitudinal section, makes this taper show slightly sturdy, and the material of energy process plays better mixed flow effect like this.
Simultaneously also can be by adjusting the extrusion pressure of the large inner material stream of mixed flow hammer size or increasing length.
The present invention uses as shown in Figure 3, and it is in the spacer shell 3 between mould flange and lathe flange, and mould flange 6 is connected on die head machine neck 7, and lathe flange 5 is connected to the output of extruder 4.
