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 utility model 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, the utility model sprue bush section thickness 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 utility model in detail.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
The utility model 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.
Embodiment 2
As shown in Fig. 6,7,8 and 9, 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.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 25, and described interface channel is provided with an entrance point and a port of export.The spacing of adjacent described passage is equal.Cooling body is cast aluminium material or copper material shape outside cooling line.。
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.As shown in Figure 9, condensate liquid enters from openend the flow direction of condensate liquid, enters into the cooling line of bottom, enters into the cooling line of last layer from interface channel, until the cooling line of top layer, flows out, thus lower the temperature to sprue bush from the port of export.Because cooling road is equally spaced cooling line, cooling line outside sprue bush arrange evenly, thus make sprue bush be heated evenly, there will not be inequality of being heated, thus by situation that sprue bush damages.
