Abstract
The utility model relates to the field of machinery, and particularly relates to a pipe extrusion mould which comprises a mouth mould and a core mould, wherein a pipeline-shaped pipe wall channel is formed between the mouth mould and the core mould. The pipe extrusion mould is characterized by also comprising a core mould slide sleeve and/or mouth mould slide sleeve, wherein the mouth mould slide sleeve is mounted on one side of the mouth mould, the core mould slide sleeve is mounted on one side of the core mould, and the inner wall of the core mould slide sleeve and/or mouth mould slide sleeve is smooth. The core mould slide sleeve and/or mouth mould slide sleeve is made of polytetrafluoroethylene. Compared with the prior art, the pipe extrusion mould provided by the utility model has the beneficial effects that the roughness and surface brightness of the outer surface and inner surface of a pipe are greatly improved by adding a section of polytetrafluoroethylene to the tail ends of the existing mouth mould and core rod according to experiments.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of tube extrusion die.
Background technology
The mouth mould of mould has determined the outer surface of pipe, and plug has determined inner surface.The mouth mould of existing mold, plug are all that die steel is made, and the surface roughness of strengthening existing mouthful of mould, plug is little to the luminance raising of tube surface.The tubing that present PE, PPR pipe mold are produced, rough surface, gloomy, affects pipe outer surface attractive in appearance, and inner surface of tube is coarse can produce certain resistance to the current of tube interior.
Utility model content
The object of utility model: a kind of pipe interior of preparing is smooth in order to provide, the tube extrusion die of outer smooth.
In order to reach as above object, the utility model is taked following technical scheme:
A kind of tube extrusion die; described mould comprises mouthful mould and core; between mouth mould and core, form the tube wall channel of pipe shape; it is characterized in that; also comprise core sliding sleeve and/or mouthful mould sliding sleeve; described mouthful of mould sliding sleeve is installed on mouthful mould one side, and described core sliding sleeve is installed on core one side, described core sliding sleeve and/or mouthful mould sliding sleeve inner wall smooth.
The further technical scheme of the utility model is, described core sliding sleeve and/or a mouthful mould sliding sleeve are polytetrafluoroethylene (PTFE).
The further technical scheme of the utility model is, described core sliding sleeve and/or a mouthful mould sliding sleeve are detachably installed on mouthful mould and core.
The further technical scheme of the utility model is, described core sliding sleeve and/or a mouthful mould sliding sleeve are annular.
The further technical scheme of the utility model is, described core sliding sleeve and/or mouthful mould sliding sleeve length are identical.
The further technical scheme of the utility model is, described core sliding sleeve and mouthful mould sliding sleeve press-fit on core and mouthful mould by core sliding sleeve platen and a mouthful mould sliding sleeve platen separately.
The further technical scheme of the utility model is, also comprises core sliding sleeve platen and a mouthful mould sliding sleeve platen are press-fited to the screw on core and mouthful mould.
The further technical scheme of the utility model is, described core sliding sleeve and mouthful mould sliding sleeve are installed on core and mouthful mould by shaggy block separately.
Adopt as above the utility model of technical scheme, with respect to prior art, there is following beneficial effect: we add one section of polytetrafluoroethylene (PTFE) existing mouthful of mould, mandrel tip, through test, show, at mouth mould, plug, add after polytetrafluoroethylene (PTFE), pipe is outer surface, inner surface no matter, and roughness, surface brightness have had significantly and promote.
Accompanying drawing explanation
In order to further illustrate the utility model, below in conjunction with accompanying drawing, further describe:
Fig. 1 is the structural representation of utility model;
Wherein: 1. mouthful mould; 2. core; 3. mouthful mould sliding sleeve; 4. core sliding sleeve; 5. mouthful mould sliding sleeve platen; 6. core sliding sleeve platen.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
A kind of tube extrusion die; described mould comprises mouthful mould 1 and core 2; between mouth mould 1 and core 2, form the tube wall channel of pipe shape; it is characterized in that; also comprise core sliding sleeve 4 and/or mouthful mould sliding sleeve 3; described mouthful of mould sliding sleeve 3 is installed on mouthful mould 1 one sides, and described core sliding sleeve 4 is installed on core 2 one sides, described core sliding sleeve 4 and/or mouthful mould sliding sleeve 3 inner wall smooths.
Any one technical scheme more than noting, provides three kinds of technical schemes, because at least can guarantee that the tubing on face is smooth.Such as, be separately core sliding sleeve 4, pipeline external is smooth.This kind of structure can be used for the pipe mold of PE, all specifications of PPR.But be not limited to this two kinds of materials.
Described core sliding sleeve 4 and/or a mouthful mould sliding sleeve 3 are polytetrafluoroethylene (PTFE).Described core sliding sleeve 4 and/or a mouthful mould sliding sleeve 3 are detachably installed on mouthful mould 1 and core 2.Therefore can also change in use for some time.
Described core sliding sleeve 4 and/or a mouthful mould sliding sleeve 3 are annular.Described core sliding sleeve 4 and/or mouthful mould sliding sleeve 3 length are identical.Therefore it is convenient to coordinate.
Described core sliding sleeve 4 and mouthful mould sliding sleeve 3 press-fit on core 2 and mouthful mould 1 by core sliding sleeve platen 6 and a mouthful mould sliding sleeve platen 5 separately.Also comprise core sliding sleeve platen 6 and a mouthful mould sliding sleeve platen 5 are press-fited to the screw on core 2 and mouthful mould 1.Therefore remove and install all very convenient.
Described core sliding sleeve 4 and mouthful mould sliding sleeve 3 are installed on core 2 and mouthful mould 1 by shaggy block separately.Known fixing means has more than one, therefore can have multiple implementation.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
