Description
Technical field
The utility model is related to a kind of manufacturing technology of hollow insulator, particularly a kind of hollow insulator flange end bag
Sealing rubber die.
Background technology
Existing hollow insulator includes silicon rubber umbrella, flange and insulation tube, and described silicon rubber umbrella is coated on absolutely
On edge pipe, the two ends of insulation tube set flange.In order to prevent insulation tube from exposing in atmosphere, using RTV (room temperature vulcanized silicon rubbers
Glue) the gap glue between flange and silicon rubber umbrella is sealed.
But this technique has the following disadvantages：
1st, the color of RTV and silicon rubber umbrella has certain difference, and during artificial gluing, it is impossible to very uniform, the meeting of smearing
Influence the aesthetic property of whole product；
2nd, the ageing resistance of RTV is very low, and several Nian Houhui produce the phenomenons such as cracking, and a certain amount of water can be entered from cracking
Point, and performance can significantly decline after insulation tube meets water, therefore the service life of whole insulator can be influenceed.
Utility model content
To solve the above mentioned problem that prior art is present, the utility model will design one kind can be improved outside hollow insulator
See, the hollow insulator flange end encapsulation die of hollow insulator service life can be extended again.
To achieve these goals, the technical solution of the utility model is as follows：Hollow insulator flange end encapsulation die,
Including die main body, contiguous block and guide pillar, described die main body profile is cuboid, and interior die cavity, institute are provided with the middle of cuboid
The interior die cavity stated is made up of small cylindrical opening, conical bore and big cylindrical hole, described small cylindrical opening internal diameter and silicon rubber umbrella end
External diameter is identical, big cylindrical hole internal diameter is identical with the external diameter of flange small-diameter end portions；Described die main body is with cuboid
The separate fixed half and moving half in heart face, fixed half and moving half is symmetrical structure, connects and composes entirety by guide pillar；Described contiguous block has
4 pieces, it is separately mounted to the two ends of die main body two sides；Described interior die cavity is connected by gum-injecting port with glue-injection machine.
Further, the thickness of described die main body is 80-85mm.
Further, the horizontal facial contour of described die main body is square.
Further, described small cylindrical opening length is 14-17mm, and circular cone hole length is 15-18mm, big cylindrical hole length
It is 19-23mm.
Further, described die main body transfer mould and cover half, die main body are fixed on moulding press by contiguous block
When, cover half up, dynamic model in lower section, fixed half and moving half is connected by two guide pillars.
Further, described contiguous block is connected by bolt with die main body.
Compared with prior art, the utility model has the advantages that：
1st, the RTV normal temperature cure silicon rubber that traditional coating technique is used, although silicon rubber can also be played a part of, but
It is the fluid silicone rubber ratio used with the utility model, either ageing resistance, or electric property and durability degree are all poor very
It is many.Therefore the utility model can significantly extend the service life of hollow insulator, and its electric property has obtained very big
Raising.
2nd, during artificial smearing RTV normal temperature cure silicon rubber, it is impossible to well-proportioned by the very perfect of the surface treatment smeared,
Always there is rough place, have a great impact to outward appearance.It is completely in mould when the utility model selects liquid glue encapsulated
Middle shaping, is not in rough place, and product appearance is improved a lot.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the scheme of installation of the utility model and hollow insulator.
In figure：1st, die main body, 2, contiguous block, 3, guide pillar, 4, gum-injecting port, 5, silicon rubber umbrella, 6, flange, 7, insulation
Pipe.
Specific embodiment
The utility model is further described through below in conjunction with the accompanying drawings.As Figure 1-3, hollow insulator flange end
Portion's encapsulation die, including die main body 1, contiguous block 2 and guide pillar 3, the described profile of die main body 1 is cuboid, in cuboid
Between be provided with interior die cavity, described interior die cavity is made up of small cylindrical opening, conical bore and big cylindrical hole, described small cylindrical opening internal diameter with
The external diameter of the end of silicon rubber umbrella 5 is identical, big cylindrical hole internal diameter is identical with the external diameter of the small-diameter end portions of flange 6；Described mould
Main body 1 is that, with the separate fixed half and moving half of cuboid median plane, fixed half and moving half is symmetrical structure, is connected and composed by guide pillar 3
It is overall；Described contiguous block 2 has 4 pieces, is separately mounted to the two ends of the two sides of die main body 1；Described interior die cavity passes through injecting glue
Mouth 4 is connected with glue-injection machine.
Further, the thickness of described die main body 1 is 80-85mm.
Further, the horizontal facial contour of described die main body 1 is square.
Further, described small cylindrical opening length is 14-17mm, and circular cone hole length is 15-18mm, big cylindrical hole length
It is 19-23mm.
Further, the described transfer mould of die main body 1 and cover half, die main body 1 are fixed on moulding press by contiguous block 2
When upper, cover half up, dynamic model in lower section, fixed half and moving half is connected by two guide pillars 3.
Further, described contiguous block 2 is connected by bolt with die main body 1.
Method of work of the present utility model is as follows：As shown in figure 3, existing hollow insulator includes silicon rubber umbrella 5, method
Orchid 6 and insulation tube 7, described silicon rubber umbrella 5 are coated on insulation tube 7, and the two ends of insulation tube 7 set flange 6.This practicality is new
When type works, fixed half and moving half is connected with moulding press respectively by 4 contiguous blocks 2, mould now is in die opening state, fixed
