Abstract
The utility model belongs to the technical field of manufacturing of PE (polyethylene) pipe molds, and aims at providing a PE pipe extruding mold which is simple to manufacture and produce and low in cost. A high-temperature-resisting bush is respectively installed on a mandrel and an extrusion die, so that the smooth finish of the inner surface and outer surface of a PE pipe can be guaranteed. The technical scheme is as follows: the PE pipe extruding mold with a bush respectively on a mandrel and an extrusion die comprises an extrusion die, a mandrel, a high-temperature-resisting extrusion die bush and a high-temperature-resisting mandrel bush, wherein the mandrel is installed inside the extrusion die, an extrusion passage is formed between the interior of the mandrel and the extrusion die, the inner wall of the extrusion end part of the extrusion die is provided with an annular groove, the high-temperature-resisting extrusion die bush is fixedly embedded in the annular groove, the outer wall of the extrusion end part of the mandrel is provided with an annular groove, the high-temperature-resisting mandrel bush is fixedly embedded in the annular groove, and an extrusion passage is also formed between the high-temperature-resisting extrusion die bush and the high-temperature-resisting mandrel bush. The PE pipe extruding mold is mainly used for producing the PE pipe with a smooth inner wall and a smooth outer wall.
Description
Technical field
A kind of plug of the utility model and mouthful mould are provided with the PE tube extrusion die of lining, belong to PE pipe mold manufacturing technology field.
Background technology
PE extruding pipe material purposes is extremely wide, such as the blow-off pipe in city; The giving of mine, drainpipe, pressure ventilation pipe, drainage gas pipe and shotcrete pipe; The protection tubes of the power cable of mine, optical cable and communication cable etc., all will use PE extruding pipe material.But because existing stainless steel mould chrome-faced layer (particularly plug and mouthful mould), because of the impact of natural environment, often gets rusty and comes off, make the inside and outside fineness of PE pipe of extruding not reach standard-required; And PE product is higher to the precision prescribed of mould, stainless steel mould just needs artificial polishing regularly, not only time-consuming but also require great effort, and has increased production cost.And the preservative oil price of die surface is high, not environmental protection again.
Utility model content
The utility model overcomes the deficiency that prior art exists, and it is simple that technical problem to be solved is to provide a kind of processing and fabricating, and PE tube extrusion die, installs resistant to elevated temperatures lining at plug and a mouthful mould cheaply, guarantees the surfaces externally and internally fineness of PE pipe.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of plug and mouthful mould are provided with the PE tube extrusion die of lining, comprise a mouthful mould, plug, high temperature resistant mouthful of die bush cover and high temperature resistant plug lining, plug be arranged on mouthful mould inside and and mouth mould between form and to extrude passage, the inwall of die extrusion end end has and in annular groove and annular groove, fixedly is inlaid with high temperature resistant mouth die bush cover, the outer wall of plug extruding end end has and in annular groove and annular groove, is fixedly inlaid with high temperature resistant plug lining, and also form and extrude passage between high temperature resistant mouthful of die bush cover and high temperature resistant plug lining.
High temperature resistant mouthful of described die bush cover and the making material of high temperature resistant plug lining are polytetrafluoroethylmaterial material, or are graphite material.
Described high temperature resistant mouthful of die bush cover and high temperature resistant plug lining are that polyfluortetraethylene plate or teflon rod fine finishining are made.
Described high temperature resistant mouthful of die bush cover and high temperature resistant plug lining are fixed in the annular groove on mouthful mould and plug by 4-8 trip bolt respectively.
The utility model compared with the existing technology has following beneficial effect.
1, the utility model is slotted and fixedly inlays high temperature resistant lining at the extruding end inside and outside wall of mouth mould and plug respectively, PE pipe can be extruded passage aftershaping through what form between two high temperature resistant linings when extruding, avoided the impact of stainless steel mould on shaped article, improved the inside and outside wall fineness of product, reduce cleaning and the polishing number of times of mould, extended the service life of mould.
2, the utility model is inlayed high temperature resistant lining respectively after the inside and outside wall fluting of mouth mould and plug, and processing is simple, easy for installation, has saved labour cost and production cost.
3, the utility model is installed high temperature resistant lining after the inside and outside wall fluting of mouth mould and plug, it is convenient when not only workman installs, also play in use positioning action, prevent that lining is subjected to displacement, high temperature resistant lining is fixed on mouthful mould and plug with 4-8 trip bolt respectively simultaneously, further to lining location, prevent from that it is in use subjected to displacement production precision is impacted.
4, high temperature resistant mouthful of die bush cover in the utility model and the making material of high temperature resistant plug lining are polytetrafluoroethylmaterial material, that this material has is high temperature resistant, corrosion-resistant, high the characteristic such as lubricate, do not adhere to, and is embedded on the plug of common stainless steel mould and mouth mould and can has greatly improved to the inside and outside wall fineness of product.
5, high temperature resistant mouthful of die bush cover in the utility model and high temperature resistant plug lining can be selected to make with polyfluortetraethylene plate or teflon rod fine finishining according to mould size dimension, have saved manufacturing cost and processing cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is a mouthful mould, and 2 is plug, 3 is high temperature resistant mouthful of die bush cover, and 4 is high temperature resistant plug lining, and 5 for extruding passage, and 6 is trip bolt.
The specific embodiment
As shown in Figure 1, a kind of plug of the utility model and mouthful mould are provided with the PE tube extrusion die of lining, comprise mouthful mould 1, plug 2, high temperature resistant mouthful of die bush cover 3 and high temperature resistant plug lining 4, plug 2 be arranged on mouthful mould 1 inside and and mouth mould 1 between form and to extrude passage 5, the inwall of mouthful mould 1 extruding end end has and in annular groove and annular groove, fixedly is inlaid with high temperature resistant mouthful of die bush and overlaps 3, the outer wall of plug 2 extruding end ends has and in annular groove and annular groove, is fixedly inlaid with high temperature resistant plug lining 4, and also form and extrude passage 5 between high temperature resistant mouthful of die bush cover 3 and high temperature resistant plug lining 4.
High temperature resistant mouthful of described die bush cover 3 and the making material of high temperature resistant plug lining 4 are polytetrafluoroethylmaterial material, or are graphite material.
Described high temperature resistant mouthful of die bush cover 3 and high temperature resistant plug lining 4 are made for polyfluortetraethylene plate or teflon rod fine finishining.
