Abstract
The utility model discloses a lightning -proof insulator column type die mould, including external mold and centre form, about being, runs from opposite directions by the external mold structure to be equipped with upper and lower end cover, its inside insulator castable chamber that is equipped with, the chamber wall setting in insulator castable chamber is hugged closely to the centre form, be provided with the inlet pipe on the external mold, the external mold outside is provided with the blast pipe, the one end of blast pipe with insulator castable chamber communicates with each other, the other end of blast pipe links to each other with the air pump, and be provided with open/close valve on the blast pipe. The utility model discloses a be provided with the air pump, pour into the reason into before the sub - castable chamber at the lightning -proof insulator blank, will discharge along the air of sub - castable intracavity portion is whole through the air pump, then open the governing valve, produce the blank with the insulator and pour into the sub - castable chamber of reason into, because the air of having discharged completely can prevent insulator surface formation blowhole, improve the yields of insulator.
Description
Technical field
This utility model is related to technical field of mold, more particularly, to a kind of anti-thunder insulator pillar compression mod.
Background technology
Insulator is the main body of transmission line insulator, and its effect is to hang wire and so that wire is kept absolutely with shaft tower, the earth
Edge.Insulator not only running voltage to be born and overvoltage effect, still suffer from simultaneously the vertical load of wire, horizontal loading and
Wire tension.Therefore, insulator must have good insulating properties and enough mechanical performances.Insulator mainly by insulating part,
Metal-ware and adhesive are constituted, wherein: 1, insulating part, and conventional is electroceramics, is a kind of inorganic insulating material, by quartz, length
Stone and clay are fired and are formed, in addition also glass, casting epoxy resin, composite insulator；2nd, metal-ware, mainly by cast iron and
Steel is made, and the guide rod of sleeve pipe typically uses copper bar or copper pipe；3rd, adhesive, will be glued to insulating part and adnexa, and the material of connection is commonly used
No. 500 portland cements.
In insulator production technology, insulator molding mould is used for the sheath of injection protection plug outside core rod of insulator
And the full skirt of increase creep age distance, mainly include the charging aperture that die cavity is connected with die cavity, by the charging aperture connecting with die cavity
The quantitative sizing material of injection completes the molding of insulator.Anti-thunder insulator, in forming process, remains air in die cavity at present, empty
Gas when being extruded by insulator blank it is not easy to be excluded completely, thus easily forming pore in insulator surface.
Utility model content
This utility model is in order to overcome deficiency of the prior art, there is provided a kind of anti-thunder insulator pillar compression mod.
This utility model is to be achieved through the following technical solutions:
A kind of anti-thunder insulator pillar compression mod, including external mold and internal model, described external mold is in split around structure, and is provided with
Upper and lower end cap, is internally provided with insulator cast die cavity, and described internal model is close to the cavity wall setting that insulator pours into a mould die cavity, described
It is provided with feed pipe on external mold, outside described external mold, be provided with exhaustor, one end of described exhaustor and described insulator cast
Die cavity communicates, and the other end of described exhaustor is connected with exhaust pump, and is provided with keying valve on described exhaustor.
As optimal technical scheme of the present utility model, one end diameter of described feed pipe is big, and other end diameter is little, diameter
Outwardly, the little one end of diameter is connected with external mold for big one end.
As optimal technical scheme of the present utility model, described feed pipe is provided with regulating valve.
As optimal technical scheme of the present utility model, the bottom of the bottom of described external mold and described exhaust pump is same flat
On face, and described exhaust pump is arranged on the side of described external mold.
Compared with prior art, the beneficial effects of the utility model are: this utility model is provided by exhaust pump,
Before anti-thunder insulator blank is injected into edge cast die cavity, by exhaust pump, the air in edge casting type intracavity portion is all arranged
Go out, be then turned on regulating valve, insulator production blank is injected in edge cast die cavity, due to being completely exhausted out air, energy
Enough prevent insulator surface from forming pore, improve the yields of insulator.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of described anti-thunder insulator pillar compression mod, including external mold 1 and internal model 2, described external mold 1 is in split around knot
Structure, and it is provided with upper and lower end cap, it is internally provided with insulator cast die cavity 3, described internal model 2 is close to the chamber that insulator pours into a mould die cavity 3
Wall is arranged, and described external mold 1 is provided with feed pipe 4, and one end diameter of described feed pipe 4 is big, and other end diameter is little, and diameter is big
Outwardly, the little one end of diameter is connected with external mold 1 for one end；And it is provided with regulating valve 8 on described feed pipe 4.
It is provided with exhaustor 5, die cavity 3 phase is poured into a mould with described insulator in one end of described exhaustor 5 outside described external mold 1
Logical, the other end of described exhaustor 5 is connected with exhaust pump 6, and is provided with keying valve 7, described external mold 1 on described exhaustor 5
Bottom and described exhaust pump 6 bottom at grade, and described exhaust pump 6 is arranged on the side of described external mold 1.
When using, it is provided by exhaust pump 6, before anti-thunder insulator blank is injected into edge cast die cavity 3, lead to
Cross exhaust pump 6 all to discharge the air that edge is poured into a mould within die cavity 3, be then turned on regulating valve 8, insulator is produced blank note
Enter and pour into a mould in die cavity 3 to edge, due to being completely exhausted out air, be prevented from insulator surface and form pore, improve insulator
Yields.
Above are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
