Abstract
The utility model discloses a polyethylene production line aircraft nose mould. Belong to polyethylene forming die technical field. It mainly be solve tubular product that current aircraft nose mould made production exist shaggy, the inside and outside wall is lackluster, and rough problem. Its leading features is: bush and mandrel including the mould steel material, the outer terminal surface of bush is fixed with the polytetrafluoroethylene outer loop, the outer terminal surface of mandrel is fixed with the polytetrafluoroethylene inner ring, this polytetrafluoroethylene outer loop is the same with polytetrafluoroethylene inner ring thickness, is in in the coplanar. The utility model has the characteristics of can make that the tubular product produced surface is smooth, the inside and outside wall is glossy and practice thrift the cost, the outer aircraft nose mould of barrel on the mainly used PE pipe material production line.
Description
Technical field
The utility model belongs to polyethylene formation technical field of mold, is specifically related to the extrusion die outside machine barrel on a kind of polyvinyl piping materials production line.
Background technology
At present, on the polyvinyl piping materials production line producing high density polyethylene (HDPE) (PE) tubing, the extrusion die outside machine barrel is generally adopted by mould steel, and the feature of mould steel to be surface roughness big, coefficient of friction is high, the tube surfaces making production is coarse, inside and outside wall is lackluster, and rough.In polyethylene raw material, add the auxiliary material of brightener etc, though can make that the tube surfaces of production is smooth, inside and outside wall is glossy, but add cost, the performance of tubing may be affected again.
Summary of the invention
The purpose of this utility model is aiming at above-mentioned weak point and provides a kind of and make that produced tube surfaces is smooth, inside and outside wall glossiness polyethylene production line extrusion die.
Technical solution of the present utility model is: a kind of polyethylene production line extrusion die, including mouth die and the core of mould steel material, it is characterised in that: it is fixed with polytetrafluoroethylene (PTFE) outer shroud in the outer face of described mouth die；It is fixed with polytetrafluoroethylene (PTFE) inner ring in the outer face of described core；This polytetrafluoroethylene (PTFE) outer shroud is identical with polytetrafluoroethylene (PTFE) inner ring thicknesses, is in same plane.
Polytetrafluoroethylene (PTFE) outer shroud described in technical solution of the present utility model, polytetrafluoroethylene (PTFE) inner ring are located by connecting with mouth die, core by screw respectively.
The utility model is due on the basis of the extrusion die that the existing mouth die by mould steel material and core are constituted, respectively in mouth die, the outer face of core is fixed with polytetrafluoroethylene (PTFE) outer shroud, polytetrafluoroethylene (PTFE) inner ring, and polytetrafluoroethylene (PTFE) outer shroud is identical with polytetrafluoroethylene (PTFE) inner ring thicknesses, it is in same plane, thus when producing high density polyethylene (HDPE) (PE) tubing, polytetrafluoroethylene (PTFE) can be made full use of high temperature resistant, high lubrication, coefficient of friction is little and does not adhere to the feature of any material, make polyethylene extrusion pass through after mouth die and mandrel molding again with in polytetrafluoroethylene (PTFE), external annular surface rubs, thus increase the fineness of tube surfaces, make tube surfaces smooth, inside and outside wall is glossy.The utility model has can make the feature that produced tube surfaces is smooth, inside and outside wall is glossy and cost-effective.The utility model is mainly used in the extrusion die on polyvinyl piping materials production line outside machine barrel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model polytetrafluoroethylene (PTFE) outer shroud and the structural representation of polytetrafluoroethylene (PTFE) inner ring.
In figure: 1-mouth die, 2-core, 3-polytetrafluoroethylene (PTFE) outer shroud, 4-polytetrafluoroethylene (PTFE) inner ring.
Detailed description of the invention
As shown in Figure 1 and Figure 2.The utility model polyethylene production line extrusion die includes mouth die 1, core 2, polytetrafluoroethylene (PTFE) outer shroud 3 and polytetrafluoroethylene (PTFE) inner ring 4.Wherein, mouth die 1 and core 2 are mould steel material, constitute existing extrusion die.Polytetrafluoroethylene (PTFE) outer shroud 3 is located by connecting by the outer face of screw with mouth die 1, and polytetrafluoroethylene (PTFE) inner ring 4 is located by connecting by the outer face of screw with core 2.Polytetrafluoroethylene (PTFE) outer shroud 3 is identical with polytetrafluoroethylene (PTFE) inner ring 4 thickness, is in same plane, and concentric.Polytetrafluoroethylene (PTFE) outer shroud 3 can determine according to the size of pipe diameter with the thickness of polytetrafluoroethylene (PTFE) inner ring 4.Polytetrafluoroethylene (PTFE) outer shroud 3 inwall, outer wall require bright and clean.
It is little and do not adhere to the feature of any material that the utility model takes full advantage of polytetrafluoroethylene (PTFE) lubrication high temperature resistant, high, coefficient of friction, by the friction with tube surfaces, plays increase tubing surfaces externally and internally brightness effect, and does not affect any performance of product.
Claims (2)
1. a polyethylene production line extrusion die, including mouth die (1) and the core (2) of mould steel material, it is characterised in that: it is fixed with polytetrafluoroethylene (PTFE) outer shroud (3) in the outer face of described mouth die (1)；It is fixed with polytetrafluoroethylene (PTFE) inner ring (4) in the outer face of described core (2)；This polytetrafluoroethylene (PTFE) outer shroud (3) is identical with polytetrafluoroethylene (PTFE) inner ring (4) thickness, is in same plane.
