Abstract
The invention discloses an integral threaded plastic rope extrusion mould which comprises a hollow cylindrical guide barrel and a hollow cylindrical extrusion barrel, wherein the guide barrel comprises a first smooth inner wall; the extrusion barrel comprises a second inner wall with a spiral groove inside; a positioning groove opening is formed in the head of the guide barrel. According to the integral threaded plastic rope extrusion mould, plastic particles can be re-arranged and extruded after entering the mould by the first smooth inner wall and the second inner wall with the spiral groove inside, so that air entering the mould is greatly reduced, pores in a plastic rope are effectively reduced, and the quality of the threaded plastic rope is effectively improved. The integral threaded plastic rope extrusion mould is simple in structure, convenient to reform and high in practicality.
Description
Technical field
The present invention relates to one and extrude processing unit (plant), or rather, is a kind of integral type screw thread plastic rope extrusion die.
Background technology
Screw thread plastic rope is a kind of novel rope of one that utilizes polymer material extrusion moulding, and surface is provided with antiskid thread, compares traditional kernmantle, and manufacturing cost is lower and intensity is suitable.Existing screw thread plastic rope is in the time extruding, and plastic grain directly enters into mould cylindraceous, because whole section of mould is all screw thread, because particle pushes at once in the time entering, easily entrained air, at the inner pore that easily forms of rope, affect the quality of screw thread plastic rope.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of integral type screw thread plastic rope extrusion die is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of integral type screw thread plastic rope extrusion die, the guide barrel cylindraceous that described integral type screw thread plastic rope extrusion die comprises a hollow and the extruded tube cylindraceous of a hollow, described guide barrel comprises a first smooth inwall, described extruded tube comprises in one establishes spiral fluted the second inwall, and the head of described guide barrel is provided with a locating notch.
As preferred embodiment of the present invention, described integral type screw thread plastic rope extrusion die is that mould steel is one-body molded, and the length of described guide barrel is 1/3rd of described extruded tube.
Integral type screw thread plastic rope extrusion die of the present invention utilize the first smooth inwall and in establish spiral fluted the second inwall, the extruding of can again arranging after plastic grain enters mould, greatly reduce the air of sneaking into, effectively reduce the pore of plastic rope inside, effectively improved the quality of screw thread plastic rope.This integral type screw thread plastic rope extrusion die is simple in structure, and transformation is convenient, practical.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
As shown in Figures 1 to 4, the guide barrel cylindraceous 2 that integral type screw thread plastic rope extrusion die 1 of the present invention comprises a hollow and the extruded tube cylindraceous 3 of a hollow, this guide barrel 2 comprises a first smooth inwall 21, this extruded tube 3 comprises the second inwall 31 of establishing helicla flute 4 in one, and the head of this guide barrel 2 is provided with a locating notch 5.
This integral type screw thread plastic rope extrusion die 1 is that mould steel is one-body molded, and the length of this guide barrel 2 is 1/3rd of this extruded tube 3.
Be not limited to this, any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
