Description
Technical field
The utility model relates to wire and cable manufacturing fields, squeeze out covered electric cable cable surface more particularly, to a kind of raising
The device of finish.
Background technique
Cable cladding mould refers to overmolded for wire and cable, and the technique for assigning certain geometrical shape and size is set
Standby, cable cladding mould belongs to annular space mouth mold, and metal core wire need to use machine to coat one layer of plastics as insulating layer on extruder
The molding of head basis.When metal core wire is monofilament or multiply metal wire, extruded product is electric wire；When metal core wire is a branch of mutual
When the conducting wire of insulation or irregular core wire, extruded product is cable, therefore it is extremely heavy in cable production process for squeezing out cladding
The single stepping wanted.
In the prior art, plastic tube extrusion production mouth mold and core model used is that steel material is process, with system
Contact surface-forming surface of product is required to polishing or chromium plating process.This structure makes the product surface finish to be formed not high；
And in use for some time, the finish of mould surface due to wear also cause under meeting drop or chrome layer local shedding,
Abrasion, can also generate scuffing trace, keep the finish of product surface worse, and the fluid transportation energy consumption of pipeline is made to increase or convey
Amount decline；Seriously affect the sale of product and beyond alignment requirements.Maintenance mouth mold and core model need the off-time also longer, and take
With also higher, serious abrasion (such as larger scratch or collision) also results in mouth mold and core model is scrapped.
Notification number CN103538234B discloses the mouth mold and core mold structure of plastics extrusion die, including mouth mold and core model,
The mouth mold be it is hollow cylindric, the core model and mouth mold coaxial arrangement are placed in the mouth mold, in the mouth mold
Surface and the core model outer surface form the first annular access of fluid flowing, also, on the outlet end of the mouth mold along with
The parallel direction of mouth mold axis is equipped with mouth mold inserts, installs on the outlet end of the core model along the direction parallel with mouth mold axis
Core model inserts forms the second annular access of fluid flowing between the mouth mold inserts and the core model inserts；Wherein, mouth mold is embedding
Part and core model inserts are all made of polytetrafluoroethylene material.It, can be with using the mouth mold and core mold structure of the plastics extrusion die
Greatly improve the finish and flatness of the inside and outside wall surface of plastic pipe.
The principle of the technology is the melt fracture in order to prevent when cable covering material polyvinyl chloride is squeezed out and coated, in mouth mold
The middle some fluoropolymers of addition, are squeezed out by a period of time, and fluoropolymer precipitate into extrusion neck ring mold surface, form lubricating film,
For improving the surface quality for squeezing out covered electric cable cable.It follows that mouth mold is intact to guarantee cable surface in process of production
Quality plays the important and pivotal role, and how to guarantee that mouth mold is intact always in process of production becomes heavy to closing in cable production
The work wanted.
Utility model content
In view of this, the purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of raising extrusion cladding electricity
The device of line cable surface finish makes mouth mold complete replacement in the case where cable is not truncated using the die geometry of split,
It remains intact, solves in cable production process, the mouth mold damage that especially whole disk happens suddenly during cable processing causes packet
Cover quality decline.
In order to achieve the above objectives, the utility model uses following technical scheme:
It is a kind of to improve the device for squeezing out covered electric cable cable surface finish, including squeeze out coating machine handpiece body, the machine
Head setting in vivo is improved the mouth mold of cable surface finish, and the mouth mold includes prod cast, gland made of metal and polytetrafluoro
Die sleeve made of ethylene, the prod cast and gland are provided with external screw thread, are fixed by the internal screw thread that handpiece body is arranged with handpiece body
Connection；The die sleeve rearward diameter is greater than front diameter, is crimped to prod cast by gland, the die sleeve is provided with circular arc in exit
Chamfering；The die sleeve and gland from least 2 parts that center line is radially divided by forming.
Further, the die sleeve is the hollow cylinder for having boss.
Further, the die sleeve is hollow round table.
Further, the length of the die sleeve is at least the 1/2 of mouth mold length.
The beneficial effects of the utility model are:
The utility model utilizes the die geometry of split, and after damaging mouth mold in process of production, cable be not truncated
In the case of can complete to replace, continue to remain intact, the quality of whole disk cable be effectively guaranteed, solve raw in cable
During production, during cable processing, the mouth mold damage of burst causes cladding quality decline to especially whole disk, causes whole disk cable
Processing failure even scrap, the huge loss that can not be retrieved caused by enterprise.
The present apparatus only uses the polytetrafluoroethylene (PTFE) material being easily lost to critical component die sleeve, for fixed and position-limiting action
Prod cast and gland still use conventional metal material, can not only effectively guarantee the processing quality of cable epidermis, be also beneficial to
The fixed effect of prod cast is improved, and keeps the stability of product and durability more preferable, and be more readily processed manufacture.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
