Abstract
The utility model relates to an electric wire Teflon coating and plastic extruding mold comprising a mould core (1) and a mold chase (2), wherein, the outer wall of the mold core (1) and the inner wall of the mold chase (2) are respectively coated with a layer of non-stick anticorrosive coating (3) composed of Teflon. The electric wire Teflon coating and plastic extruding mold has the advantages that the self lubricity during plastic extruding is good, the quality of the plastic extruding surface is better than that of the common mold, the anticorrosive performance of the mold is good, the service life is long, plastic materials cannot stick on the surface of the mold, the cleaning of the mold is very convenient, and the operating time is saved.
Description
Technical field
The utility model relates to the electric wire extruded mould.
Background technology
Because polytetrafluoroethylene (PTFE) (being Teflon) molecule has the fluorine-containing shell of one deck inertia outward, make it have outstanding not viscosity can with low coefficient of friction.Have outstanding high temperature resistance and chemical stability.Its purposes relates to industrial circles such as Aero-Space, petrochemical industry, machinery, electronics, building, light textile.Therefore polytetrafluoroethylene (PTFE) has the laudatory title of " plastics king ".Teflon coating is to be the coating of the specific use of base material with the polytetrafluoroethylene (PTFE), has been widely used at present in non-stick pan coating layer and the injection mold, has well utilized polytetrafluoroethylene (PTFE) not viscosity energy and resistance to elevated temperatures.My company is used for the exploitation of electric wire Teflon coating extruded mould, mainly is the principle of having used for reference non-stick pan, utilizes the not viscosity energy of polytetrafluoroethylene (PTFE), low coefficient of friction and outstanding high temperature resistance and chemical stability, and exploitation forms.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of electric wire Teflon coating extruded mould, and perishable to solve in the prior art, high defective rubs.
Technical scheme
The utility model provides a kind of electric wire Teflon coating extruded mould, comprises being divided into core rod and die sleeve two parts, and coated inner wall one deck of the outer wall of described core rod and die sleeve is not stained with anticorrosive coat, and this layer is made of Teflon.
Described Teflon is selected from polytetrafluoroethylene (PTFE), ethylene fluoride third rare copolymer, crosses the copolymer of fluoroalkylation thing or ethene and tetrafluoroethene.
Beneficial effect
Extruded mould belongs to shaper, be divided into core rod and die sleeve two parts, the sizing material of extruding machine extrusion plasticizing is extruded the adhesive tape of tubulose continuously or strip by die surface, and is coated on the cable element, so the sizing material surface quality influence of the surface action of mould after product is extruded is bigger.Its surface lubrication that die surface greatly improves after applying by Teflon is improved the sizing material surface.In extrusion process, because the effusion corrosive gas can appear decomposing in plastic material material in plasticizing process, certainly will produce corrosion to die surface, cause die life to shorten, after die surface applies by Teflon, the iron and steel material quality that easily is corroded does not directly contact with the extrusion molding sizing material, and Teflon itself has excellent corrosion resistance, has therefore guaranteed the service life of mould.In addition, conventional mould uses the back sizing material attached on the mould, manual cleanup, will bake heating with fire sometimes during cleaning, and strike off gradually with scraper, and is time-consuming.Can clearly easily remove at hot state by the mould sizing material after the Teflon coating, the back sizing material that turns cold can not stick on the mould yet, has saved the time of cleaning mould.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, 2, 3, a kind of electric wire Teflon coating extruded mould comprises being divided into core rod 1 and die sleeve 2 two parts, the outer wall of described core rod 1 and, coated inner wall one deck of die sleeve 2 is not stained with anticorrosive coat 3, this layer is made of polytetrafluoroethylene (PTFE).
As shown in Figure 1, 2, 3, a kind of electric wire Teflon coating extruded mould comprises being divided into core rod 1 and die sleeve 2 two parts, the outer wall of described core rod 1 and, coated inner wall one deck of die sleeve 2 is not stained with anticorrosive coat 3, this layer is made of ethylene fluoride third rare copolymer.
As shown in Figure 1, 2, 3, a kind of electric wire Teflon coating extruded mould comprises being divided into core rod 1 and die sleeve 2 two parts, the outer wall of described core rod 1 and, coated inner wall one deck of die sleeve 2 is not stained with anticorrosive coat 3, this layer is made of mistake fluoroalkylation thing.
Embodiment 4
As shown in Figure 1, 2, 3, a kind of electric wire Teflon coating extruded mould comprises being divided into core rod 1 and die sleeve 2 two parts, the outer wall of described core rod 1 and, coated inner wall one deck of die sleeve 2 is not stained with anticorrosive coat 3, the copolymer of this layer ethene and tetrafluoroethene constitutes.
Claims (2)
1. an electric wire Teflon coating extruded mould comprises being divided into core rod (1) and die sleeve (2) two parts that it is characterized in that: coated inner wall one deck of the outer wall of described core rod (1) and die sleeve (2) is not stained with anticorrosive coat (3), and this layer is made of Teflon.
2. electric wire Teflon coating extruded mould as claimed in claim 1 is characterized in that: described Teflon is selected from polytetrafluoroethylene (PTFE), ethylene fluoride third rare copolymer, crosses the copolymer of fluoroalkylation thing or ethene and tetrafluoroethene.
