Description
Technical field
The present invention relates to a kind of heat-shrinkable T bush processing mold.
Background technology
Heat-shrinkable T bush has a very wide range of applications in productive life, little of electronic products such as mobile phones, has use heat-shrinkable T bush greatly in aircraft and boats and ships.But in the production of heat-shrinkable T bush, there are some problems, outward appearance, chemical property and other mechanical property can be affected as extruded rough surface.
Summary of the invention
The technical problem to be solved in the present invention is: the shaggy defect overcoming traditional heat-shrinkable T bush, there is provided a kind of heat-shrinkable T bush bright extrusion die, the surface of the heat-shrinkable T bush of extrusion molding is brighter, careful, reduce the impact of outward appearance and the chemical property brought due to rough surface, heat-shrinkable T bush quality is better and reliable and stable.
In order to solve the problems of the technologies described above, the present invention proposes following technical scheme: a kind of heat-shrinkable T bush bright extrusion die, and it comprises plug, plug polytetrafluoroethylene (PTFE) cover, pad, plug lock-screw, mouth mould, mouth mould polytetrafluoroethylene (PTFE) cover, several mouthful of mould lock-screw;
Plug is a revolving body, is made up of metal material;
The leading section of plug digs the plug mounting groove of an annular;
The forward end of lateral surface of plug has a core rod forming surface;
The front end face center of plug has dug a bolt apertures;
Plug polytetrafluoroethylene (PTFE) cover is annular, is made up of polytetrafluoroethylmaterial material;
Plug polytetrafluoroethylene (PTFE) cover is arranged in plug mounting groove;
The outer surface of plug polytetrafluoroethylene (PTFE) cover and the core rod forming surface smoothing transition of plug;
Pad is set on plug lock-screw;
Plug lock-screw is locked in the bolt apertures of plug, and pad is securely fixed in the front end of plug plug polytetrafluoroethylene (PTFE) cover;
The centre drill of plug lock-screw is provided with steam vent;
Mouth mould is the revolving body of an inner hollow, is made up of metal material;
Mouth die sleeve is located at around plug;
The leading section of mouth mould digs the mouth mould mounting groove of an annular;
The forward end of medial surface of mouth mould has a mouth mold forming surface;
The front end face of the mouth mould mounting groove of mouth mould several bolt apertures have been dug;
Mouth mould polytetrafluoroethylene (PTFE) cover is annular, is made up of polytetrafluoroethylmaterial material;
Mouth mould polytetrafluoroethylene (PTFE) puts and offers several installing holes;
Mouth mould polytetrafluoroethylene (PTFE) cover is arranged in mouthful mould mounting groove;
Several mouthful of mould lock-screw, through several installing holes, is then locked in several bolt apertures of mouthful mould, mouth mould polytetrafluoroethylene (PTFE) cover is securely fixed in the front end of mouthful mould;
The inner surface of plug polytetrafluoroethylene (PTFE) cover and the mouth mold forming surface smoothing transition of mouth mould;
The coefficient of friction of the outer surface of plug polytetrafluoroethylene (PTFE) cover and the inner surface of plug polytetrafluoroethylene (PTFE) cover is less than the coefficient of friction on core rod forming surface and mouth mold forming surface.
Compared with prior art, the present invention has following beneficial effect: PUR is after core rod forming surface and mouth mold forming surface, finally arrive between the outer surface of plug polytetrafluoroethylene (PTFE) cover and the inner surface of plug polytetrafluoroethylene (PTFE) cover shaping, because the coefficient of friction of the outer surface of plug polytetrafluoroethylene (PTFE) cover and the inner surface of plug polytetrafluoroethylene (PTFE) cover is much smaller than core rod forming surface and the coefficient of friction on mouth mold forming surface, therefore the surface of the heat-shrinkable T bush of last extrusion molding is brighter, careful, reduce the impact of outward appearance and the chemical property brought due to rough surface, heat-shrinkable T bush quality is better and reliable and stable.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of heat-shrinkable T bush of the present invention bright extrusion die.
Detailed description of the invention
Refer to Fig. 1, the present invention proposes a kind of heat-shrinkable T bush bright extrusion die, and it comprises plug 1, plug polytetrafluoroethylene (PTFE) cover 2, pad 3, plug lock-screw 4, mouth mould 5, mouth mould polytetrafluoroethylene (PTFE) cover 6, several mouthful of mould lock-screw 7.
Plug 1 is a revolving body, is made up of metal material.
The leading section of plug 1 digs the plug mounting groove 12 of an annular.
The forward end of lateral surface of plug 1 has a core rod forming surface 14.
The front end face center of plug 1 has dug a bolt apertures 16.
Plug polytetrafluoroethylene (PTFE) cover 2 is annulars, is made up of polytetrafluoroethylmaterial material.
Plug polytetrafluoroethylene (PTFE) cover 2 is arranged in plug mounting groove 12.
The plug polytetrafluoroethylene (PTFE) cover outer surface of 2 and the core rod forming surface 14 of plug 1 seamlessly transit.
Pad 3 is set on plug lock-screw 4.
Plug lock-screw 4 is locked in the bolt apertures 16 of plug 1, and pad 3 is securely fixed in the front end of plug 1 plug polytetrafluoroethylene (PTFE) cover 2.
The centre drill of plug lock-screw 4 is provided with steam vent 41.
Mouth mould 5 is revolving bodies of an inner hollow, is made up of metal material.
Mouth mould 5 is set in plug 1 around.
The leading section of mouth mould 5 digs the mouth mould mounting groove 52 of an annular.
The forward end of medial surface of mouth mould 5 has a mouth mold forming surface 54.
