Abstract
The utility model discloses a design cover that contour machining of plastics tubular product was used, including the body that has the entrance with export the section be equipped with stepped section on the inner wall of the entrance of body, be equipped with in stepped section the surface with the polytetrafluoroethylene or the modified ultrahigh molecular weight polyethylene coating of body export section inner wall parallel and level. The utility model has the advantages that: simple structure can effectual assurance tubular product outward appearance precision, conveniently realizes continuous production, and production efficiency improves.
Description
Technical field
The utility model relates to a kind of plastic pipe process equipment, especially relates to the shaping cover for plastic pipe molding.
Background technology
The shaping cover used in the molding process of plastic pipe mostly at present is steel or copper material, and its inwall machining accuracy is higher, can ensure shaping after plastic pipe external diameter meet standard-required.The thermoplastic materials pipe extruded from extruder moves continuously along shaping cover, and in motion process cool, shaping.Due to can the low molecule auxiliary agents such as paraffin be separated out when thermoplastic materials pipe cools, be easy to stick on the inwall of shaping cover, thus cause shaping after tube surfaces have cut, affect tubing outward appearance, interval cleaning in 2 hours is needed once when serious, not only significantly reduce production efficiency, and increase percent defective.
Summary of the invention
The purpose of this utility model be to provide a kind of tube forming effective, can quantity-produced plastic pipe molding processing shaping cover.
Technical solution of the present utility model is: a kind of shaping cover of plastic pipe molding processing, comprise the body with entrance and outlet section, the inwall of the entrance of described body is provided with end difference, in end difference, is provided with the outer surface polytetrafluoroethylene (PTFE) concordant with described body outlet section inwall or modified ultra-high molecular weight polyethylene coating.
Polytetrafluoroethylene (PTFE) or modified ultra-high molecular weight polyethylene coating have self-lubricating effect, the low molecule auxiliary agents such as the paraffin that not easily during the cooling of plastic adherent tubing, surface is separated out, coating surface can keep level and smooth, and it is concordant with outlet section inwall, the moulding plastics tube surfaces extruded from shaping cover does not have cut, tube outer diameter is even, can realize continuous seepage.
The outlet section of described body is provided with the cooling water hole of through outlet section inside and outside wall.Can cooling effectiveness be improved, and can continue to discharge the low molecule auxiliary agents such as the surperficial paraffin of separating out of plastic pipe, be conducive to realizing continuous seepage.
The entrance of described body is provided with the cooling water hole of pass-through entry section inside and outside wall and polytetrafluoroethylene (PTFE) or modified ultra-high molecular weight polyethylene coating.Improve the cooling effectiveness of entrance, and the low molecule auxiliary agents such as the paraffin of in time plastic pipe surface being separated out, be conducive to realizing continuous seepage.
The utility model has the advantages that: structure is simple, effectively can ensure tubing outward appearance precision, conveniently realize continuous seepage, production efficiency improves.

Detailed description of the invention
Embodiment:
Consult Fig. 1-2, a kind of shaping cover of plastic pipe molding processing, comprise the body 1 with entrance 5 and outlet section 6, the inwall of the entrance 5 of body 1 is provided with end difference 3, in end difference 3, is provided with the outer surface polytetrafluoroethylene (PTFE) concordant with outlet section 6 inwall of body 1 or modified ultra-high molecular weight polyethylene coating 2.The outlet section 6 of body 1 is provided with the cooling water hole 4 of through outlet section 6 inside and outside wall, the entrance 5 of body 1 is provided with the cooling water hole 4 of pass-through entry section 5 inside and outside wall and polytetrafluoroethylene (PTFE) or modified ultra-high molecular weight polyethylene coating 2.
After thermoplastic materials tubing enters from the entrance 5 of body 1, can move along polytetrafluoroethylene (PTFE) or modified ultra-high molecular weight polyethylene coating 2, and be shaped by outlet section 6.In motion process, the low molecule auxiliary agents such as the paraffin of separating out are discharged outside main body 1 by the cooling water hole 3 being arranged on entrance 5 place, can not accumulate at polytetrafluoroethylene (PTFE) or modified ultra-high molecular weight polyethylene coating 2 surface, namely cooling water hole 4 on outlet section 6 can discharge the low molecule auxiliary agent of precipitation, can pass into again cooling water and improve cooling effectiveness.Plastic pipe smooth surface after sizing, external diameter indicator consilience is high, and shaping cover main body 1 inwall is not easy stuck foreign matter, can keep higher smoothness, be conducive to continuous seepage.
Above-listed detailed description is illustrating for one of the utility model possible embodiments, this embodiment is also not used to limit the scope of the claims of the present utility model, allly do not depart from the equivalence that the utility model does and implement or change, all should be contained in the scope of the claims of this case.
Claims (3)
