Continuous extrusion device with double right-angle channels

The invention relates to a continuous extrusion device with double right-angle channels. The continuous extrusion device comprises a second extrusion mold (35) which comprises a second extrusion cavity (36). The front side of the second extrusion cavity (36) is provided with a second feed channel (37), an upper feed pressurization channel (42), a lower feed pressurization channel (42), a left feed pressurization channel (42) and a right feed pressurization channel (42), and the rear side of the second extrusion cavity (36) is provided with a central discharge channel (38). Certain include angles are formed between the four feed pressurization channels (42) and the central line of the second extrusion cavity (36). The central discharge channel (38) is provided with the first right-angle channel (39) and the second right-angle channel (40) which are each internally provided with a plunger chip. By adoption of the continuous extrusion device, continuous production of copper-chromium-zirconium alloy contact lines
