[0024] Working principle and usage process of this utility model:

[0025] In use, liquid metal or liquid plastic is injected into the diversion pipe 5, which then distributes the liquid to the first injection pipe 4, the first inlet pipe 6, and the second inlet pipe 7. Liquid can be injected into the first injection channel 10 through the first injection pipe 4, into the second and third injection channels 11 and 12 through the first inlet pipe 6, and into the fourth and fifth injection channels 13 and 14 through the second inlet pipe 7. The diameters of the first, second, third, fourth, and fifth injection channels 10 and 14 decrease sequentially, allowing for the simultaneous processing of wires of different diameters. The first valve 8 and the second valve 9 control the flow rate of the liquid within the first injection pipe 4, the first inlet pipe 6, and the second inlet pipe 7, respectively. After forming, the processed part is ejected by the ejector pin 20.
