Abstract
The utility model provides a PVC -U tubular product extrusion tooling's die sleeve, includes: constitute T type structure by cylinder and the ring flange that sets up in cylinder one end, the cylinder center is equipped with the circular channel that runs through its both ends, and the ring flange end of circular channel is described for loudspeaker, the parcel has ring heater, its characterized in that on the cylinder: the tail end of cylinder is equipped with and improves this section temperature to about 300 degrees high temperature heating regions. Utilize the high temperature heating who sets up at the die sleeve tail end regional, can improve die sleeve tail end temperature to 300 degrees left and right sides. Make tubular product extrude the process in the completion, the high temperature heating who increases on former zone of heating basis distinguishes, makes PVC -U type tubular product break away from pipe box brush to the tail end zone of heating, improves the heating temperature of bush, reaches and improves the surperficial degree of becoming more meticulous of PVC -U type tubular product to improve PVC's shearing force, increase its soffening ability, make surface gloss promote. This kind of improvement can not exert an influence to the physics mechanical properties of die sleeve itself.
Description
Technical field
Newly what relate to is extrusion die with novel for this, especially a kind of PVC-U tube extrusion dieDie sleeve.
Background technology
At present, pipe production producer is more and more, and market competition becomes a flash point increasingly; How to make certainlyOneself product has market competing more in the case of not raising the cost or paying less costStriving power, is pendulum problem in the urgent need to address in face of each producer. Existing PVC-U tubing squeezesThe die sleeve that goes out mould is generally T-shaped structure, that is: by cylinder be arranged on cylinder one endRing flange forms, and described cylinder center is provided with the circular channel that runs through its two ends, circular channelRing flange end be horn-like. Though the die sleeve of the PVC-U tube extrusion die of this structure can be fullThe requirement of foot PVC-U tube extrusion, but the PVC-U outer pipe wall glossiness of its extrusion molding is low,Affect the outward appearance of product.
Utility model content
The technical problems to be solved in the utility model is to make up above-mentioned the deficiencies in the prior art, providesA kind of die sleeve of the PVC-U tube extrusion die that improves outer pipe wall glossiness.
Technical problem of the present utility model is solved by the following technical programs.
The die sleeve of this PVC-U tube extrusion die, comprising: by cylinder be arranged on cylinderThe ring flange of body one end forms T-shaped structure, and described cylinder center is provided with runs through its two endsCircular channel, the ring flange end of circular channel is horn-like, on described cylinder, is enclosed with electric heatingCircle.
The die sleeve feature of this PVC-U tube extrusion die is:
Described cylindrical tail end is provided with and can improves this section of temperature to 300 degree left and right high-temperature heatingsRegion.
The technical problem of the die sleeve of the utility model PVC-U tube extrusion die is by entering below oneThe technical scheme of step is solved.
Described heating region is by the annular groove around the setting of cylinder tail end lateral wall and settingHigh-temperature electric hot line therein, is at least provided with one for tail end electricity perpendicular to cylinder breech faceThe tail end temperature sensing hole of hot line conduction.
Described cylinder breech face is also provided with a temperature sensing hole for subsequent use. Due to the aperture of tail end temperature sensing holeLess, connect for a long time tail end heating wire,, wearing and tearing aging at tail end heating wire, when fracture in, mayStop up, cause and cannot normally use, so temperature sensing hole for subsequent use is set.
The utility model beneficial effect is compared with prior art:
The die sleeve of the utility model PVC-U tube extrusion die is on existing die sleeve basisImprovement, utilize and be arranged on the high-temperature heating region of die sleeve tail end, can improve die sleeve tail end temperatureTo 300 degree left and right. Make tubing complete injection moulding process, the height increasing on basis, the former thermal treatment zoneThe temperature thermal treatment zone, makes PVC-U type tubing touch the tail end thermal treatment zone in disengaging pipe box moment, improvesThe heating-up temperature of mouth mould, reaches the degree of becoming more meticulous that improves PVC-U type tube surfaces, to improveThe shearing force of PVC, increases its plasticizing capacity, and surface gloss is promoted. This improvement is rightThe physical and mechanical property of die sleeve itself can not exert an influence. The improvement of this die sleeve is simple,Very easily operation, does not need additionally to increase cost. And increase tubing outward appearance score value, be beneficial to similarThe competitiveness of product in market.
Below in conjunction with detailed description of the invention and contrast accompanying drawing the utility model is described.
Brief description of the drawings
Fig. 1 is the die sleeve structure schematic diagram of PVC-U tube extrusion die.
Detailed description of the invention
Embodiment: the die sleeve that can be clear that PVC-U tube extrusion die from Fig. 1 is basicStructure is identical with existing die sleeve: by cylinder 1 and the ring flange 2 that is arranged on cylinder 1 one endForm T-shaped structure, described cylinder 1 center is provided with the circular channel 3 that runs through its two ends,Ring flange 2 ends of circular channel 3 are horn-like 4, on described cylinder 1, are enclosed with electric heating coil5, cylinder 1 is provided with temperature sensing hole 6.
Difference is: the tail end 7 of described cylinder 1 is provided with and can improves this section and spend to temperature 300High-temperature heating region, left and right. Described heating region by around cylinder tail end 6 lateral walls arrangeAnnular groove 8 and set tail end heating wire 9 therein, and perpendicular to cylinder breech face11 tail end temperature sensing holes 10 that conduct for tail end heating wire 9 that are provided with form.
Described cylinder breech face 11 is also provided with a temperature sensing hole 12 for subsequent use. Temperature sensing hole 12 for subsequent useThe reason that arranges be: because the aperture of tail end temperature sensing hole is less, connect for a long time tail end heating wire,Tail end heating wire is aging, may stop up when wearing and tearing, fracture, causes and cannot normally use.
The design principle of the die sleeve of the utility model PVC-U tube extrusion die is: utilize and arrangeIn the high-temperature heating region of die sleeve tail end, can improve die sleeve tail end temperature to 300 degree left and right. MakeTubing completes extrusion, and the high-temperature heating district increasing on basis, the former thermal treatment zone, makes PVC-UTubing touches the tail end thermal treatment zone in disengaging pipe box moment, improves the heating-up temperature of mouthful mould, reachesThe degree of becoming more meticulous that improves PVC-U type tube surfaces, to improve the shearing force of PVC, increases itPlasticizing capacity, promotes surface gloss.
Above content be in conjunction with concrete preferred embodiment, the utility model is done enter oneStep describes in detail, can not assert that concrete enforcement of the present utility model is confined to these explanations. RightIn the utility model person of an ordinary skill in the technical field, not departing from, this practicality is newUnder the prerequisite of type design, its framework form can be flexible and changeable, can subseries product. OnlyBe to make some simple deduction or replace, all should be considered as belonging to the utility model by submitted toThe scope of patent protection that claims are definite.
