Description
Technical field
This utility model relates to field of plastics manufacture, is specifically related to a kind of expanded material extrusion mould-outlet adjusting means.
Background technology
At present, major part PS(polystyrene) foam sheet extruder, it is all by changing that the thickness of its extrusion sheet adjusts
Become what interior local gap between die lip 5, outer die lip 4 realized.Concrete structure is shown in Fig. 4.Uniform on the outer ring circumference of die lip 4 outside
There are 12 location hole, outside uniform 12 screws on the inner ring relevant position of die lip 4, screw built-in regulation bolt, regulate bolt
Through the screw on inner ring, and insert in hole, location.When there is the phenomenon of became uneven the sheet material local of extrusion, adjusted by rotation
Joint bolt, regulation bolt acts on the active force of the outer ring of outer die lip 4 and will change, the inner ring of outer die lip 4 can be made to produce small
Elastic deformation so that outer die lip 4 changes with the gap of interior die lip 5 corresponding position, so that the thickness of extrusion sheet obtains
To adjust.The mode major defect of this regulation thickness is: needing to make outer die lip 4 inner ring produce elastic deformation, metal produces bullet
Property deformation need bigger external force, relatively elaborate when therefore adjusting.It addition, regulation regulates bolt repeatedly, outer die lip reaches tired
After the limit, inner ring is easily broken off, and the service life of mouth die is the longest.
Utility model content
The purpose of this utility model is to provide a kind of expanded material extrusion mould-outlet adjusting means, to solve existing extruder
Outer die lip easily rupture because of tired, and the problem shortening the mouth die life-span.
For reaching above-mentioned purpose, base case of the present utility model is as follows:
Expanded material extrusion mould-outlet adjusting means includes die body, core body, interior die lip and outer die lip；It is also associated with on die body supplying
The union joint that adventitia lip connects, described outer die lip connects with being connected head shoot, and described union joint is provided with flange, and flange is provided with many
Individual and outer die lip end face offsets and circumferential equally distributed pressure regulating mechanism；Described die body, union joint, outer lip mould, core rod and
Epipharynx module synthesis runner.
The principle of this programme expanded material extrusion mould-outlet adjusting means is:
Owing to outer die lip connects with being connected head shoot, outer die lip can rotate towards each side；Pressure regulating mechanism and outer die lip
End face offset, be controlled with the position of external die lip, the power of the most a certain pressure regulating mechanism die lip end face outside produces and becomes
During change, the stressing conditions of adventitia lip will change, the relative position change of outer die lip and interior die lip.
When became uneven occurs in the foam sheet of extrusion, according to the thickness situation of its extrusion sheet, corresponding adjustment pressure
Power governor motion is added in the pressure of outer die lip end face, and outer die lip will be relative to rotating with union joint, and outer die lip and interior die lip
Position relatively also will change；Therefore by regulation pressure regulating mechanism, then the gap at runner exit can be made to reach consistent,
So that the thickness of the foam sheet of extrusion is uniform.
This programme produces and provides the benefit that:
In this programme, outer die lip can rotate on union joint, and the active force on pressure regulating mechanism die lip outside changes, outward
Die lip will relatively and union joint produce fine rotation, the most compared with prior art the outer die lip in this programme will not produce relatively
Big elastic deformation, thus avoid outer die lip and easily rupture because of tired, the problem shortening the mouth die life-span.
Preferred version one: as the further optimization to base case, described pressure regulating mechanism includes regulating bolt, institute
Stating and offer screwed hole on flange, regulation bolt is screwed in screwed hole, and regulation bolt screw rod end offsets with outer die lip end face；
By screwing regulation bolt, generation is changed, so that adventitia lip is relative to union joint by the pressure of regulation bolt die lip end outside
Deflection；This preferred version simple in construction, owing to regulation bolt rigidity is relatively big, so applying the power strengthened about during regulation, the most excellent
Scheme one is selected to be applicable to regulate the less occasion of probability.
Preferred version two: as the further optimization to preferred version one, the end of described regulation bolt is provided with elastic component；
In preferred version one, the direct contacts side surfaces with outer die lip of screw rod of regulation bolt, owing to the rigidity of regulation bolt is very big, because of
This only regulates a certain regulation bolt, and outer die lip is only capable of a minute angle of deflection, therefore when needs outer die lip deflection larger angle
Time, it is necessary to multiple regulation bolts cooperate；And elastic component is set in the end of regulation bolt, regulation spiral shell can be reduced accordingly
Bolt and the rigidity of external mold lipped joint contravention so that externally the regulation of die lip is more convenient.
Preferred version three: as the further optimization to base case, described pressure regulating mechanism includes screw rod, and screw rod is solid
It is scheduled on described flange, and screw rod is relative with the end of described outer die lip；Screw rod is provided with the elastic component offseted with outer die lip end face,
The adjusting nut between flange and elastic component it is additionally provided with on screw rod.In preferred version three, by regulation adjusting nut, adjust
The pressure of elastic component will be changed by joint nut, and then the pressure of elastic component external die lip end face also changes, thus reach outside regulation
The effect of die lip；Owing to elastic component rigidity is relatively small, then the required power applied can reduce, therefore lighter during regulation.
Preferred version four: as the further optimization to base case, described pressure regulating mechanism is provided with 12 altogether, to carry
Top adjustment precision；But pressure regulating mechanism continues to increase, then can increase assembly difficulty, and then increase cost.
Preferred version five: as the further optimization to preferred version four, the sidewall of described outer die lip is provided with locking screw holes,
Lock-screw it is provided with in locking screw holes；After die lip is adjusted in place outside, outer die lip can be locked by lock-screw；Especially in pressure
When the rigidity of power governor motion is less, lock-screw can effectively prevent outer die lip by External force interference.
Preferred version six: as the further optimization to preferred version five, be provided with compact heap in described locking screw holes, described
Lock-screw screw rod offsets with compact heap upper surface, and compact heap lower surface is set to match with the sphere of described union joint bulb
Concave surface；The concave surface of compact heap contacts with the bulb of union joint can increase contact area, and then strengthens locking effect.
Preferred version seven: as the further optimization to preferred version six, described compact heap lower surface is provided with anti-skidding lines,
Anti-skidding lines can optimize the locking effect of lock-screw further.
