The outlet of the powder runner is connected with a forming runner which is coaxial with the powder runner. The molding runner is divided into a heating area and a cooling area, the heating area is provided with a heating device, and the cooling area is provided with a cooling device. The mould is also provided with a valve needle, the valve needle comprises a rear needle positioned in the powder runner and a front needle positioned in the molding runner, and a channel is arranged at the joint of the rear needle and the front needle.
As a further improvement, the powder runner and the forming runner are detachably connected.
As a further improvement, the heating area and the cooling area are detachably connected.
As a further improvement, a heat insulation layer is arranged between the heating zone and the cooling zone.
As a further improvement, a metal pipe cutting device is arranged after the molding runner.
As a further improvement, a heat treatment device is arranged between the forming runner and the heat treatment device and is used for improving the strength of the metal pipe.
As a further improvement, a first fixing device is provided between the heat treatment device and the cutting device for supporting the metal tube against deformation such as bending.
As a further improvement, a second fixing device is arranged between the forming runner and the heat treatment device.
As a further improvement, a heat insulation layer is arranged between the heating zone and the cooling zone.
As a further improvement, a heat insulation layer is arranged between the powder runner and the molding runner.
When the superfine seamless metal pipe is manufactured, mixed metal powder is pressed into a powder runner through a screw, is continuously heated in the powder runner and enters a forming runner through a channel on a valve needle, the metal powder is heated to be molten in a heating area of the forming runner, and a molten mass is filled in a gap between the forming runner and the front needle of the valve needle and is cooled and formed in a cooling area.
The invention has the advantage that the invention can manufacture the ultra-fine seamless metal pipe with the diameter of more than or less than 0.2 mm.

FIG. 2 is an enlarged view of a portion of the present invention.
Detailed Description
The main body of the apparatus for manufacturing an ultra-fine seamless metal pipe shown in fig. 1 to 2 is a mold 1 including a powder flow passage 2 and a molding flow passage 3. The die 1 is provided with a plurality of powder runners 2 and corresponding molding runners 3 according to production requirements, and the powder runners 2 are provided with preheating devices, so that metal powder entering the molding runners 3 has a certain temperature. And a forming flow channel 3 which is coaxial with the powder flow channel 2 is arranged at the outlet of the powder flow channel 2. The powder flow passage 2 and the molding flow passage 3 may be integrally molded or may be separately manufactured and assembled together. A heat insulation layer 13 is arranged between the powder runner 2 and the molding runner 3. The front part of the forming flow passage 3 is provided with a heating zone, a heating device 4 is arranged on the heating zone, and metal powder is melted through the heating device 4. The rear part of the molding runner 3 is a cooling area, a cooling device 5 is arranged on the cooling area, and the melt can be cooled and molded through the cooling device 5. The heating zone is made of high temperature resistant material. The heating zone and the cooling zone can be integrally formed or can be manufactured separately and then assembled together. Between the heating and cooling zones a thermal insulation layer 12 is installed. The inner bore diameters of the forming runners 3 are different to produce metal pipes of different outer diameters. The mold 1 is further provided with a valve needle 6, the valve needle 6 is a reducing body and is divided into a front needle 61 and a rear needle 62, the front needle 61 is positioned in the molding runner 3, and the rear needle 62 is positioned in the powder runner 2. The diameter of the rear needle 62 is larger than that of the molding runner 3 and is tightly pressed against the outlet of the powder runner 2. The diameter of the front needle 61 corresponds to the inner diameter of the metal tube. The rear needle 62 is provided with a channel 7 at a portion connected with the front needle 61, and two ends of the channel 7 are respectively communicated with the powder flow channel 2 and the molding flow channel 3.
