Hollow block is sector structure；Hollow block is formed by following structure：Two side shapes positioned at this inside and outside side of the sealing ring
Into through hollow-core construction, the left and right sides be adjacent solid slug, up and down both sides be articulamentum, articulamentum and adjacent solid slug
Integration connection, the inward flange for being vertically connected with layer is connected to laminating upper lip and laminating lower lip；With sky on the outside of the solid slug
Heart block is concordant, inner side is longer than on the inside of hollow block and is shorter than the vertical projection length of laminating upper lip and lower lip of fitting.
It is preferred that, the thickness of the articulamentum is 2-9mm.
The present invention also provides a kind of sealing ring production mould, and the above-mentioned sealing ring for producing, the production mould includes
The external mold of internal model and annular, the internal model is identical with the center of circle of external mold, and the internal model includes cylindrical stent and annular
Shaping mould, shaping mould socket is fixed on the center of the stent, the excircle of shaping mould and the external mold
The distance between inner periphery is equal to the distance between internal and external circumference of the sealing ring body, and the shaping mould, which is provided with, is used for shape
Into the groove of the solid slug, the groove is spaced apart, and is respectively equipped with through hole at the top and bottom of the groove, it is described into
Above and below the inner periphery of pattern, stent be provided with the lip groove for forming the laminating upper lip and lower lip of fitting, it is described logical
Hole is connected with the lip groove.
Technical scheme provided in an embodiment of the present invention can include following beneficial effect：
The present invention provides a kind of sealing ring and sealing ring production mould, and the sealing ring includes the sealing ring body of annular
The sealing ring body includes solid slug and sky of annular array, mutual integrally connected centered on the circle of sealing ring body
Heart block, the solid slug and hollow block are spaced, and the top edge and lower edge of the inner periphery of the solid slug are connected to
Laminating upper lip and laminating lower lip；Above-mentioned solid slug and hollow block are sector structure；Hollow block is formed by following structure：Position
Form the hollow-core construction run through sideways in two of this inside and outside side of the sealing ring, the left and right sides be adjacent solid slug, on
Lower both sides are articulamentum, and articulamentum connection integrated with adjacent solid slug, the inward flange for being vertically connected with layer is connected to patch
Close lip and laminating lower lip；, inner side concordant with hollow block is longer than on the inside of hollow block and is shorter than upper lip of fitting on the outside of the solid slug
With the vertical projection length of laminating lower lip.The sealing ring that the present invention is provided, the design of laminating upper lip and laminating lower lip makes sealing ring
Fitted with by sealed object closer, sealing effectiveness is more preferable；When there is the situation of local upperlip failure, due to hollow block energy
Water is separated, under the water of passive state is acted under the surface tension of water, water still can not can not be penetrated into by sealer, close
Envelope property is good, and be particularly suitable for use in anhydrous pressing-type waterproof.

Embodiment
In order that those skilled in the art more fully understand the technical scheme in the present invention, below in conjunction with of the invention real
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described implementation
Example only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, art technology
The every other embodiment that personnel are obtained under the premise of creative work is not made, should all belong to the protection model of the present invention
Enclose.
Referring to Fig. 1 to Fig. 3, Fig. 1 show a kind of overlooking the structure diagram of sealing ring provided in an embodiment of the present invention.
From Fig. 1 to Fig. 3, the sealing ring includes the sealing ring body 10 of annular, and the sealing ring body 10 is wrapped
Solid slug 11 and hollow block 12 of annular array, mutual integrally connected centered on the circle of sealing ring body 10 are included, it is described
Solid slug 11 and hollow block 12 are spaced, and the top edge and lower edge of the inner periphery of the solid slug 11 are connected to laminating
Upper lip 13 and laminating lower lip 14；Above-mentioned solid slug 11 and hollow block 12 are sector structure；Hollow block 12 passes through following structure
Formed：Two of outside form the hollow-core construction run through sideways in the sealing ring body 10, and the left and right sides is adjacent
Solid slug 11, up and down both sides are articulamentum 15, and the thickness of articulamentum 15 is 2mm, articulamentum 15 and the adjacent one of solid slug 11
Change connection, the inward flange for being vertically connected with layer 15 is connected to laminating upper lip 13 and laminating lower lip 14；The outside of solid slug 11
Concordant with hollow block 12, the described inner side of solid slug 11 is longer than the inner side of hollow block 12 and is shorter than fit upper lip 13 and lower lip 14 of fitting
Vertical projection length.
In the present embodiment, the top edge and lower edge of the inner periphery of the solid slug 11 and the hollow block 12 are connected respectively
There are laminating upper lip 13 and laminating lower lip 14, in use, laminating upper lip 13 and laminating lower lip 14 can be with closely being pasted by sealed object
Close, sealing effectiveness more preferably, and has certain elasticity；During for waterproof sealing, during use, even if laminating upper lip 13 and patch
Close lower lip 14 and breakage occur, because sealing ring body 10 is spaced by solid slug 11 and hollow block 12, water can enter hollow block
In 12, hollow block 12 separates water, and water in an unstressed state, due to the effect of surface tension, still can not be passed through close
Seal, therefore, sealing ring of the invention is particularly suitable for use in no pressing-type waterproof.
The embodiment of the present invention also provides a kind of sealing ring production mould, above-mentioned sealing ring, such as Fig. 4 and Fig. 5 for producing
