Background technology
The casting system of die casting is made up of sprue bush, runner, cast gate, and in casting process, molten metal directly enters mold cavity through sprue bush, runner, cast gate.
A water shutoff circle is provided with outside the sprue bush of the die casting of prior art, sprue bush is provided with the flowing groove of a cooling fluid, cooling fluid is sealed by water shutoff circle and sprue bush close-fitting, when sprue bush work is heated, sprue bush deforms, cooling fluid is easily leaked, and causes die casting product fraction defective to improve.On the sprue bush material that cooling fluid is directly done, the violent change of sprue bush internal-external temperature difference is large, and cause material easily to ftracture, the end falls in the sprue bush life-span.
Summary of the invention
Due to the above-mentioned shortcoming of prior art, the present invention proposes a kind of pouring bushing for die casting die, and it is yielding that it can effectively solve the sprue bush existed in prior art, and cooling fluid is revealed, and the shortcoming of the service life reduction of sprue bush.
The present invention is by the following technical solutions:
A kind of pouring bushing for die casting die, comprise a sprue bush, be arranged with a water shutoff circle outside it, described water shutoff circle comprises a cooling body and the entrance point be located on described cooling body and the port of export, and described entrance point and the described port of export are communicated with the cooling line being located at described cooling body interior respectively.
Described cooling line is the one in copper pipe, aluminum pipe, iron pipe or stainless steel tube.
Described cooling line is spirality.
Described cooling line is equal pitch spirality.
Described cooling line is the passage being located at the some annulars of described cooling body interior, and the two ends of adjacency channel are communicated with respectively by a connection channel, and described interface channel is provided with an entrance point and a port of export.
The spacing of adjacent described passage is equal.
Described cooling line is that a pipeline is first bent into S shape, then is bent into circular rear formation.
Described cooling body is that outside described cooling line, cast aluminium material or copper material are formed.
The described port of export and described entrance point are threaded a condensate circulation system.
The present invention has the following advantages: with copper pipe or iron pipe pitch of the laps, as cooling fluid circulation duct, outside cast aluminium or copper are as Heat Conduction Material, oral area processing tube tooth is twisted and is connect copper pipe soon and be connected with outside cooling recirculation system, can effectively ensure that cooling system does not leak, improve the yield of die-cast product, cooling fluid does not act directly on sprue bush simultaneously, reduce the cold and hot violent change of sprue bush material, reduce material cracks risk, extend sprue bush service life, because cooling passage is opened at water shutoff circle inner, compare biography sprue bush, sprue bush section thickness of the present invention remains unchanged, reduce sprue bush distortion, and risk of breakage.

detailed description of the invention:
Below in conjunction with detailed description of the invention, describe the present invention in detail.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
The present invention discloses a kind of pouring bushing for die casting die, and with copper pipe or iron pipe pitch of the laps, as cooling fluid circulation duct, outside cast aluminium or copper are as Heat Conduction Material, and oral area processing tube tooth is twisted and connect copper pipe soon and be connected with outside cooling recirculation system.
Embodiment 1
As shown in Fig. 3,4 and 5, a kind of pouring bushing for die casting die, comprise a sprue bush 1, a water shutoff circle 2 is arranged with outside it, described water shutoff circle comprises a cooling body 21 and the entrance point 22 be located on described cooling body and the port of export 23, and described entrance point and the described port of export are communicated with the cooling line 24 being located at described cooling body interior respectively.Cooling line is the one in copper pipe, aluminum pipe, iron pipe or stainless steel tube.Cooling line is spirality, and is equal pitch spirality.The port of export and described entrance point are threaded condensate circulation system.Cooling body is that outside cooling line, cast aluminium material or copper material are formed.
The present embodiment in use, water shutoff snare is located at the outside of sprue bush, the port of export and entrance point are threaded connection the external condensation circulatory system, due to the one that cooling line is in copper pipe, aluminum pipe, iron pipe or stainless steel tube, cooling body is that aluminium or copper material are formed, and therefore its heat conductivility is good, and the heat of sprue bush can conduct on cooling line easily via water shutoff circle, by the condensed fluid of cooling line inside, the heat of sprue bush is taken away, thus lower the temperature to sprue bush.
