Abstract
The utility model relates to an extruding hole mold sleeve which comprises a stainless steel outer ring and a polytetrafluoroethylene inner ring fixedly arranged on a hole mold body, wherein the polytetrafluoroethylene inner ring is buckled on the inner wall of the stainless steel outer ring; an annular water tank is arranged between the polytetrafluoroethylene inner ring and the stainless steel outer ring; a first sealing ring and a second sealing ring are respectively arranged on two sides of the annular water tank; a water inlet and a water outlet communicated with the outside are formed in the annular water tank. The extruding hole mold sleeve has the beneficial effects that the structure is reasonable, the design is novel, through the improvement of an existing mold sleeve, the length of a flow pass is prolonged, the melt hole mold expansion is reduced, so that the smooth flow and forming of materials are facilitated; through the improvement of a front end material of the hole mold, the polytetrafluoroethylene inner ring is additionally arranged, the surface smoothness of a pipe material is greatly improved by using good lubrication anti-attrition performance under a high-load condition.
Description
Technical field
The utility model relates to a kind of extrusion die sleeve.
Background technology
At present, when producing TPO plastic pipe, on market, using the mouth die body of extruder is all the copper-plated stainless steel of pure stainless steel or top layer, plastics high-temperature fusant is through mouthful cooling extrusion modling of mould, high viscosity due to TPO high-temperature fusant, with and and stainless steel between frictional property, not only, even there is cut in shaping pipe outward appearance.
Utility model content
The purpose of this utility model is to provide a kind of extrusion die sleeve, the problems referred to above that exist to solve existing product.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of extrusion die sleeve, comprise the stainless steel outer ring and the polytetrafluoroethylene (PTFE) inner ring that are fixed on mouthful mould body, described polytetrafluoroethylene (PTFE) inner ring is snapped on the inwall of described stainless steel outer ring, between polytetrafluoroethylene (PTFE) inner ring and described stainless steel outer ring, be provided with annular tank, annular tank is provided with water inlet and the delivery port being communicated with outside.
Further, be along the circumferential direction equidistantly provided with some screws on described stainless steel outer ring, described stainless steel outer ring is fastenedly connected by hexagon socket head cap screw and described mouthful of mould body.
Further, described annular tank both sides are respectively equipped with sealing ring one and sealing ring two.
The beneficial effects of the utility model are: rational in infrastructure, modern design, by the improvement to existing die sleeve, has extended the length of runner, have reduced melt mouth mould and have expanded, and are beneficial to smooth flow and the sizing of material; By the improvement of counterpart mould front end material, increase polytetrafluoroethylene (PTFE) inner ring, utilize its lubricated Wear vesistance good under top load condition, greatly promoted tube surfaces smoothness.
