Abstract
The invention discloses a water stop cock. The water stop cock comprises a cock body, an elastic sheet, an O-shaped ring and a cock screw, wherein a cock screw hole is formed in the cock body and is provided with a chamfer; the cock screw is mounted in the cock screw hole, and the shape of the cock screw is a trapezoid; the elastic sheet is mounted on the cock body and is of an unconnected circular ring; the O-shaped ring is mounted on the cock body and is made from water-swellable rubber. Through the manner, the water stop cock disclosed by the invention has no need of tooth tapping, never gets rusty, can be subjected to random tightness adjustment, has no need of a leakage stopping belt, can be moved randomly and be placed at any position in a water flow passage and is good in heat conductivity.
Description
Technical field
The present invention relates to mould applications, relate in particular to a kind of water stop bolt.
Background technique
Water stop bolt is to be used in the cooling or heating system of mould water channel, the flow direction of water channel is played to the metal parts of wad act.In order effectively to control the flow direction of water channel, industry has proposed higher requirement to the sealability of water stop bolt, in addition, when can water stop bolt be operated in environment its sealability that remain valid of lower time colded and heat succeed each other, be also the major criterion whether check water stop bolt performance meets the requirements.Yet in use, its sealability is difficult to reach desirable and requires or standard existing water stop bolt usually, correspondingly, water stop bolt water leakage phenomenon may occur in use, to production, brings negative effect, and may cause product yield to descend.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of water stop bolt, and this water stop bolt does not need tapping, and Never-rusty can arbitrarily be adjusted degree of tightness, without the antidiarrheal band, can arbitrarily move, and is positioned over the arbitrary position in the water channel runner, and thermal conductivity is good.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of water stop bolt comprises: key, shell fragment, O type ring and peg are provided with a peg hole in described key;
Described peg is arranged in described peg hole;
Described shell fragment is arranged on described key;
Described O type ring is arranged on described key.
In a preferred embodiment of the present invention, described shell fragment is disjunct annulus.
In a preferred embodiment of the present invention, the material of described O type ring is hydro-expansive rubber.
In a preferred embodiment of the present invention, described peg aperture is provided with chamfering.
In a preferred embodiment of the present invention, being shaped as of described peg is trapezoidal.
The invention has the beneficial effects as follows: water stop bolt of the present invention does not need tapping, and Never-rusty can arbitrarily be adjusted degree of tightness, without the antidiarrheal band, can arbitrarily move, and is positioned over the arbitrary position in the water channel runner, and thermal conductivity is good.
The accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of water stop bolt of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, key; 2, shell fragment; 3, O type ring; 4, peg; 5, peg hole.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises: a kind of water stop bolt, comprise: key 1, shell fragment 2, O type ring 3 and peg 4, be provided with a peg hole 5 in described key 1,5 mouthfuls, described peg hole is provided with chamfering, the inclination of the inclination of chamfering and described peg 4 always, contributes to described peg 4 to coordinate closely with described peg hole 5.
Described peg 4 is arranged in described peg hole 5, and being shaped as of described peg 4 is trapezoidal, and along with external temperature increases, temperature more high pressure is larger, and the pressure of 4 pairs of water stop bolt walls of described peg is larger, better tightness.
Described shell fragment 2 is arranged on described key 1, and described shell fragment 2 is disjunct annulus, and along with going deep into of described peg 4, described shell fragment 2 can constantly increase, and makes sealability strengthen.
Described O type 3 rings are arranged on described key 1, and the material of described O type ring 3 is hydro-expansive rubber, and hydro-expansive rubber is met volume inflatable 1 times or several times after water, thereby block the water of seepage, reach the purpose of waterproof.
Below the working principle of water stop bolt of the present invention described in detail.
The water channel of water stop bolt being put into to mould during use is located, make peg 4 match with peg hole 5 on key 1, along with external temperature increases, temperature more high pressure is larger, the pressure of 4 pairs of water stop bolt walls of peg is larger, thereby make shell fragment 2 constantly increase and block water channel, if while using for the first time, O type ring 3 chance water can constantly expand, make sealing more remarkable.
Compared with prior art, water stop bolt of the present invention does not need tapping, and Never-rusty can arbitrarily be adjusted degree of tightness, without the antidiarrheal band, can arbitrarily move, and is positioned over the arbitrary position in the water channel runner, and thermal conductivity is good.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
