Abstract
The utility model discloses a mold for winding glass fibers on an insulation tube. The mold comprises a mold main body, wherein a Teflon surface coating layer is arranged on the surface of the mold main body. In order to improve the adhesive force of the Teflon surface coating layer, the sand blasting treatment for increasing the surface roughness is implemented for the surface of the mold main body; the Teflon surface coating layer is coated on the surface of the mold main body after the sand blasting treatment. The Teflon surface coating layer can be a polytetrafluoroethylene surface coating layer. The mold for winding the glass fibers on the insulation tube has excellent wear resistance, corrosion resistance and oxidation resistance, and can effectively prolong the service life of the metal mold; in addition, the Teflon material additionally has excellent viscosity, lubricity and very low friction coefficient, and can reduce the mold release difficulty of workpieces; a release agent is not required to apply on the surface of the mold during producing.
Description
Technical field
The utility model discloses a kind of metal die, specifically a kind of mould for glass fiber winding insulation tube.
Background technology
The production metal die of traditional glass fiber winding insulation tube (cylinder), in order to reduce demoulding difficulty, die surface roughness requires high, for improving anti-corrosive properties and the non-oxidizability of mould, generally also will carry out surface treatment (generally electroplating one deck hard chrome coating).And glass fiber material itself has higher wearability, although die surface has sprayed one deck releasing agent when workpiece is manufactured, during the demoulding, die surface also can be subject to damage in various degree, affects the service life of mould.
Summary of the invention
The problem existing in order to overcome prior art, the purpose of this utility model is to provide a kind of mould for glass fiber winding insulation tube, this glass fiber winding insulation tube (cylinder) is produced and has been changed conventional fabrication processes with metal die, the metal cutting requirement on machining accuracy of die surface is not high, surface is after metal processing, carry out again blasting treatment, improve surface roughness to increase the affinity of Teflon coating and mould metal surface.
The purpose of this utility model is achieved through the following technical solutions:
A mould for glass fiber winding insulation tube, comprises die ontology, it is characterized in that: on die ontology surface, be provided with Teflon face coat.
In the utility model, for improving the adhesive force of Teflon face coat, increase the blasting treatment of surface roughness on the surface of die ontology, Teflon face coat is coated in the die ontology surface after blasting treatment.Described Teflon face coat can be ptfe surface coating.
Teflon(Teflon) be that E.I.Du Pont Company is used the registration mark on its a series of fluoropolymer polymer products, polytetrafluoroethylene (PTFE) is most widely used product, has the laudatory title of " King ".There is preferably not viscosity, heat resistance, sliding and moisture resistance, there is excellent corrosion resistance and non-oxidizability simultaneously, apply very extensive.
Different from traditional metal mold production process, after the utility model Surface Machining, first carry out blasting treatment, and then be coated with one deck Teflon (Teflon) coating.Compared with prior art, the utility model covers after one deck PTFE coating at die surface, and for Design of Dies and maintaining bring very big benefit, concrete advantage is:
1, because PTFE has good not viscosity and sliding, has extremely low coefficient of friction simultaneously, make the workpiece depanning position demoulding easier, it is more a little bit smaller that demoulding angle can design, and also need not use releasing agent;
2, improved the anticorrosive and non-oxidizability of die surface, the mould of stainless steel material can consider to use ordinary steel coating to process in the past, reduced die manufacturing cost;
3,, after the workpiece demoulding, mould only need carry out adopting easy clean to process, and need not carry out antirust processing, simplifies maintaining flow process.
The utility model is applicable in the production of glass fiber winding insulation tube (cylinder).
figure of description
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A mould for glass fiber winding insulation tube described in the utility model, is shown in Fig. 1, and this mould comprises die ontology 1, and die ontology is made by ordinary steel.On the surface of die ontology, increase the blasting treatment of surface roughness, the die ontology surface after blasting treatment applies one deck Teflon face coat 2, and this Teflon face coat is ptfe surface coating.Blasting treatment has improved the adhesive force of Teflon face coat.
In the utility model, because PTFE has good not viscosity and sliding, has extremely low coefficient of friction simultaneously, make the workpiece depanning position demoulding easier, it is more a little bit smaller that demoulding angle can design, and also need not use releasing agent; Improved the anticorrosive and non-oxidizability of die surface, the mould of stainless steel material was used ordinary steel coating to process in the past, reduced die manufacturing cost; After the workpiece demoulding, mould only need carry out adopting easy clean to process, and need not carry out antirust processing, simplifies maintaining flow process.
