Abstract
A plastic-wood vibration extruding-out die is composed of extruder flange, cavity, washer and vibrating plate. The outlet part of die has guide posts, guide sleeves, spring, vibration source and lubricant injecting orifice. It features use of vibration to make material be easily separated from die.
Description
Technical field
The present invention relates to a kind of injection moulding die head, particularly relate to a kind of wood vibrations extrusion die of moulding.
Background technology
In the prior art, because when macromolecule extrusion process, it is not high to mould wooden degree of refinement, and material is in being squeezed into type mouth mould the time, between material and the mold wall, because frictional resistance, material generation shear action causes material extrusion die difficulty, the material that is extruded, because its density unevenness is even, and causes material surface rough.
Summary of the invention
The objective of the invention is to design a kind of wood vibrations extrusion die of moulding, increase vibroseis and lubricant medium inlet thereon, vibroseis can be according to the numerical value feedback regulation vibration frequency of pressure measxurement monitor, the lubricant medium lightening material with the frictional resistance between mold wall so that material is thrown off die orifice smoothly.
The wood vibrations extrusion die of moulding that the present invention relates to is realized as follows: it includes extruder, ring flange, cavity volume, it also comprises the mould outlet position of being made up of backing plate, concussion plate, the mould outlet position is equipped with guide pillar, guide pin bushing, spring respectively, vibroseis, lubricant medium inlet; Screw is arranged on the backing plate, and trip bolt is by the through hole of ring flange, cavity volume, screws on the backing plate in the screw, make ring flange, cavity volume, backing plate three parts are fastening is an integral body, the flange of ring flange and extruder flange are connected to a fixed.
Described moulding in the wood vibrations extrusion die, the lubricant medium inlet is arranged on the outer surface of backing plate cross section.
Described moulding in the wood vibrations extrusion die, vibroseis is arranged on the interior recess in the concussion plate outer face.
Described moulding in the wood vibrations extrusion die at outlet of extruder end inwall, is embedded with the pressure measurement probe.
When work, mould extruder screw in the wood vibrations extrusion die because the reaction of material, the interior pressure increases, lubricant medium injects dies cavity, lightening material is with the frictional resistance between mold wall, and vibroseis can be regulated vibration frequency according to the numerical value feedback of pressure probe, so that material is thrown off die orifice smoothly.
The good effect of moulding wood vibrations extrusion die that the present invention relates to is: when macromolecule extrusion process, it is not high to mould wooden degree of refinement, increase vibroseis and lubricant medium inlet thereon, lubricant medium injects dies cavity, vibroseis provides vibration frequency, significantly reduce plastic-wood material with the frictional resistance between the mold wall, the feasible plastic-wood material that is in fluid state, in the middle of moulding the outlet of wood vibrations extrusion die, locate to reduce greatly with the relative velocity of exit wall vicinity, reduce loss, improved product quality.
Description of drawings
Accompanying drawing is a Y sectional structure schematic diagram of the present invention.
In the accompanying drawing:
1 extruder, 2 pressure measurement probe, 3 ring flanges, 4 cavity volumes, 5 backing plates, 6 concussion plates,
7 vibroseises, 8 guide pillars, 9 guide pin bushings, 10 springs, 11 lubricant medium inlets.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further.
As shown in drawings, an embodiment who moulds wood vibrations extrusion die of the present invention: it includes extruder 1, ring flange 3, cavity volume 4, it also comprises the mould outlet position of being made up of backing plate 5, concussion plate 6, the mould outlet position is equipped with guide pillar 8, guide pin bushing 9, spring 10 respectively, lubricant medium inlet 11, on the backing plate 5 screw is arranged, trip bolt is by the through hole on ring flange 3, the cavity volume 4, screw on the backing plate 5 in the screw, make ring flange 3, cavity volume 4, backing plate 5 three parts are fastening is an integral body, the flange of ring flange 3 and extruder 1 flange are connected to a fixed.Lubricant medium inlet 11 is arranged on the outer surface of backing plate cross section, and vibroseis 7 is arranged on the interior recess in concussion plate 6 outer faces, is embedded with pressure measurement probe 2 at extruder 1 port of export inwall.
When work, mould extruder 1 screw rod in the wood vibrations extrusion die because the reaction of material, the interior pressure increases, lubricant medium injects dies cavity, lightening material is with the frictional resistance between mold wall, and vibroseis 7 can be regulated vibration frequency according to the numerical value feedback of pressure probe 2, so that material is thrown off die orifice smoothly.
The present invention moulds the vibroseis 7 in the wood vibrations extrusion die, can adopt electromagnetic type or mechanical vibroseis 7, and what adopted in the present embodiment is the electromagnetic type electromagnetic shaker.
