Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example

[0027] An integrated feed tube for cold chamber die casting, such as Figures 1-10As shown, it comprises a feeding pipe 1, an inlet 2, a pushing port 3 and an injection port 4; the feeding pipe 1 is a hollow pipe with both ends open, one end of the feeding pipe 1 is the pushing port 3, and the other end is the injection port 4;

[0028] It also comprises a circulating lumen and a plugging head 301; the feeding pipe 1 is provided with a circulating lumen, and the circulating lumen penetrates the pipe wall to form a plurality of through holes, and each through hole is plugged by the plugging head 301;

[0029] Each first opening 1011, second opening 1021, third opening 1301 and fourth opening 2011 is plugged by the plugging head 301, and the shape of the plugging head 301 corresponds to the shape of the plugged through hole.

[0030] The circulating lumen is composed of a plurality of cooling pipelines distributed up and down, and the size of the cooling pipeline is adjusted according to the actual setting position;

[0031] The cooling pipeline closest to the pushing port 3 comprises a cooling channel and a connecting channel 103; the feeding pipe 1 wall is provided with two left and right cooling channels; the two cooling channels are connected through the connecting channel 103.

[0032] Each cooling channel comprises a liquid channel 101 and an arc channel; the feeding pipe 1 wall is provided with a liquid channel 101, and the liquid channel 101 penetrates one end of the pushing port 3 of the feeding pipe 1, and the through hole of the liquid channel 101 is the first opening 1011; the feeding pipe 1 wall is provided with an arc channel, and the arc channel is in communication with the liquid channel 101.

[0033] Each arc channel comprises a group connecting channel 102; the feeding pipe 1 is provided with a plurality of group connecting channels 102, one end of the group connecting channel 102 penetrates the outer wall of the feeding pipe 1 to form a second opening 1021, the number of group connecting channels 102 is set according to the actual opening position; and the adjacent two group connecting channels 102 are in communication with each other; the group connecting channel 102 closest to the liquid channel 101 is in communication with the liquid channel 101; the two group connecting channels 102 in the front are connected through the connecting channel 103, and the connecting channel 103 penetrates the outer wall of the feeding pipe 1 to form two third openings 1301.

[0034] It also includes a series channel 201; when viewed from front to back, the liquid channel 101 on the right side of the center line of the feed pipe 1 is the first liquid flow area; the liquid channel 101 on the left side of the center line of the feed pipe 1 is the second liquid flow area; all liquid channels 101 in the first liquid flow area are connected in series through the series channel 201; all liquid channels 101 in the second liquid flow area are connected in series through another series channel 201, and both series channels 201 pass through the outer wall of the feed pipe 1, and each generates a fourth opening 2011.

[0035] Before using the device, remove any one of the plugging heads 301 that blocks the first opening 1011 of the first liquid flow area. The first opening 1011 is the liquid inlet.

[0036] Remove any one of the plugging heads 301 that blocks the first opening 1011 of the second liquid flow area. The first opening 1011 is the liquid outlet.

[0037] Connect the external pump to the liquid inlet, connect the external recovery device to the liquid outlet, then connect the connecting part 5 to the external mold, and insert the external propeller into the propulsion port 3;

[0038] Then, the molten metal is poured from the feed port 2 into the hollow cavity of the feed pipe 1 manually or by machine. Then, the external pusher starts working to press the molten metal from the hollow cavity of the feed pipe 1 into the external mold. In this way, the device realizes the basic work of introducing molten metal.

[0039] At the same time as the molten metal enters the cavity in the feed pipe 1, the external pump starts working to introduce the coolant from the liquid inlet into the corresponding liquid channel 101, and since all the liquid channels 101 in the first liquid flow area are connected in series through the series channel 201, the coolant will pass through the series channel 201 and enter all the liquid channels 101 in the first liquid flow area (for the convenience of description, the coolant in the first liquid flow area is referred to as the "first coolant"). After that, the first coolant in the liquid channel 101 in the first liquid flow area passes through the grouping channel 102 and the connecting channel 103 at the corresponding position and flows into the grouping channel 102 in the second liquid flow area. At this time, the first coolant begins to change to an outflow state (the coolant in the outflow state is referred to as the "second coolant"). After that, the second coolant flows out from the liquid outlet through the grouping channel 102, the liquid channel 101 and the series channel 201 in the second liquid flow area.

[0040] When the coolant flows through the first liquid flow area and the second liquid flow area, it absorbs the heat generated by the device when receiving the molten metal, thereby achieving the cooling work of the device and avoiding the problem of deformation or cracking of the material pipe in the prior art after long-term contact with high-temperature molten metal;

[0041] And through the setting of the group connecting channels 102, it is not necessary to connect each first liquid flow area first opening 1011 with an external pump, and it is not necessary to connect each second liquid flow area first opening 1011 with an external recovery device, thereby greatly reducing the use cost of the device;

[0042] And the liquid channels 101, the group connecting channels 102, the connecting channels 103 and the series connecting channels 201 constituting the circulating cavity of the device can be drilled in the feed pipe 1 through a conventional drilling machine, and the processing mode is very simple, thereby avoiding the problem that the prior art setting of the first example cooling cavity 11 (corresponding to the conventional slotting mode of the prior art) causes the feed pipe wall to be thinned, and the physical properties of the feed pipe to be deteriorated;

[0043] And the problem that the prior art setting of the second example cooling cavity 12 (corresponding to the tubular cooling cavity of the prior art) causes the processing difficulty of the curved part of the second example cooling cavity 12 to be high, and the use cost of the feed pipe to be too high is also avoided.

[0044] The above only describes the preferred embodiments of the present application, and it should be noted that for ordinary skilled persons in the art, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
