Abstract
The invention discloses a die head of a plastic extruding machine. The die head comprises an outer sleeve (1) and an inner sleeve (8), wherein the inner sleeve (8) is sleeved in the outer sleeve (1) to form a material channel (7). The die head is characterized in that an inner lantern ring (3) and an outer lantern ring (2) are connected with the front ends of the inner sleeve (8) and the outer sleeve (1) respectively; the outer lantern ring (2) is fixed on the outer sleeve (1) in an interference fit way; the inner lantern ring (3) and the outer lantern ring (2) are both made from polytetrafluoroethylene plastic; the inner lantern ring (3) is fixed on the inner sleeve (8) through a gasket (6) and a bolt (5). The die head provided by the invention has the characteristics of simple structure, convenience in replacement, high resistance to corrosion and good stability.
Description
Technical field
The invention belongs to field of mechanical technique, relate in particular to a kind of extruder die.
Background technology
In plastic extruding forming equipment, plastic extruder is referred to as main frame conventionally, and the follow-up equipment plastic extruding forming machine supporting with it is called subsidiary engine.Die head is exactly plastic extruder " machine thorax ", is to realize the vitals of extruding.Die head is comprised of inner sleeve and outer sleeve.Inner sleeve is except jointly accepting electrical heating with outer sleeve, by conduct radiation, fuselage is play outside " thermal source " effect, most important effect is to coordinate with extruding screw, realization is to the fragmentation of plastics, softening, melting, exhaust preliminary compacting, bearing the effect of carrying continuously and equably sizing material to formation system, thereby inner and outer sleeves is subject to HTHP for a long time, rubbed for a long time and be operated under the effect of Korrosionsmedium.Thereby die head front end is to be vulnerable to most these impacts and to deform or be corroded affected the smoothness of die head, and stationarity makes the product processing not reach desirable index.In prior art, inner sleeve and outer sleeve are all formed in one, and corrosion resistance is poor.After the front end of inner sleeve and outer sleeve damages, get to know and scrap, necessary integral replacing, production cost is high.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and provide a kind of simple in structure, change convenient, anticorrosive strong, die mechanism that stationarity is good.The smoothness that the product of producing is produced than common die head is better, and without regularly clearing up die head residue, saving of work and time, saves the electricity charge, and in start process, waste product is few, cost-saving.Due to the equal sizing not of mouth core rod mould, more mold exchange is more convenient.
Object of the present invention and solve its technical problem underlying and realize by the following technical solutions:
Extruder die of the present invention, comprise outer sleeve, inner sleeve, this inner sleeve is placed on formation circulation road in outer sleeve, and wherein: described inner sleeve, outer sleeve are connected with the front end of inner sleeve and outer sleeve respectively, its outer sleeve is by the fixing outer sleeve of interference fit.
Above-mentioned extruder die, wherein: described inner sleeve is screwed on inner sleeve by pad.
Above-mentioned extruder die, wherein: the material of described inner sleeve and outer sleeve all adopts polytetrafluoroethylplastic plastic.
The present invention compared with prior art, there is obvious beneficial effect, as can be known from the above technical solutions: inner sleeve, outer sleeve are connected with the front end of inner sleeve and outer sleeve respectively, its outer sleeve by interference fit be fixed on outer sleeve, inner sleeve is screwed on inner sleeve by pad.The inside and outside collar replaceable, need not change whole outer sleeve or inner sleeve while making inner and outer sleeves that wearing and tearing or corrosion occur, and has saved the replacement cost of die head.Inside and outside sleeve adopts polytetrafluoroethylene (PTFE) as material, increased the smoothness of die head inwall, chemical stability due to polytetrafluoroethylene (PTFE), corrosion resistance, it is one of decay resistance optimal material in the world today, in water, boil also and do not change, have sealing, high lubricated not viscosity, electrical insulating property and good ageing resistance, heatproof excellent (can long-term work at the temperature of+250 ℃ to-180 ℃).Polytetrafluoroethylene (PTFE) itself does not have toxicity to people.Improve the performance of high temperature resistant, high pressure resistant, the hole corrosion of die head, improved the stability of die head.In a word, the present invention has feature simple in structure, that replacing is convenient, anticorrosive by force, stationarity is good.
Accompanying drawing explanation
Fig. 1 is that of the present invention cuing open shown structure intention.
Mark in figure:
1, outer sleeve; 2, outer sleeve; 3, inner sleeve; 4, hole; 5, screw; 6, pad; 7, logistics corridor; 8, inner sleeve.
the specific embodiment:
Below in conjunction with accompanying drawing and preferred embodiment, the extruder die specific embodiment, structure, feature and effect thereof to proposing according to the present invention, be described in detail as follows.
Referring to Fig. 1, extruder die of the present invention, comprise outer sleeve 1, inner sleeve 8, this inner sleeve 8 is placed on the interior formation circulation road 7 of outer sleeve 1, wherein: described inner sleeve 3, outer sleeve 2 are connected with the front end of outer sleeve 1 with inner sleeve 8 respectively, its outer sleeve 2 is by the fixing outer sleeve of interference fit 1.Described inner sleeve 3 is fixed on inner sleeve 8 by pad 6 use screws 5.The material of described inner sleeve 3 and outer sleeve 2 all adopts ABS plastic.
During use, from the material of extruding machine, by logistics corridor 7, i.e. extruding between outer sleeve 1 and inner sleeve 8, evacuate, then uniform discharge.And in this process, be the most easily stressed, the part of high temperature, corrosion is outer sleeve 2 and inner sleeve 3, because outer sleeve 2 is by the fixing outer sleeve of interference fit 1, inner sleeve 3 is fixed on inner sleeve 8 by pad 6 use screws 5, and all adopt ABS to mould manufacture, so outer sleeve 2 and the replaceable collar of inner sleeve 3, and corrosion resistance is strong.In a word, the present invention has replaced the die head of one, has improved the stability of die head, changes timely the precision that the collar has also improved die head, makes the product accuracy of discharging higher, and reliability is stronger.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any content that does not depart from technical solution of the present invention, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
Claims (3)
1. an extruder die, comprise outer sleeve (1), inner sleeve (8), this inner sleeve (8) is placed on the interior formation circulation road of outer sleeve (1) (7), it is characterized in that: described inner sleeve (3), outer sleeve (2) are connected with the front end of outer sleeve (1) with inner sleeve (8) respectively, its outer sleeve (2) is by the fixing outer sleeve of interference fit (1).
2. extruder die as claimed in claim 1, is characterized in that: the material of described inner sleeve (3) and outer sleeve (2) all adopts ABS plastic.
