During extrusion molding, combustible gas filled in the three groups of heating gas transmission pipes 8 is ignited, unheated aluminum materials are inserted into the extrusion channel shell 1, the aluminum materials are pushed to extrude and slide through the extrusion push rod 2, the ignited combustible gas heats the aluminum materials in the sliding process, the heated aluminum materials firstly pass through the conical surfaces formed by all the adjusting blocks 48 before passing through the forming die 3, and extrusion resistance is reduced through the conical surfaces; then extruded and molded by a molding die 3; in the extrusion process, after the push block 6 arranged on the extrusion push rod 2 slides to be matched with the guide chute 5 formed in the extrusion channel shell 1, the push block 6 slides along the guide chute 5, in the sliding process, after the three push blocks 6 are contacted with the three trigger push rods 25, the push block 6 starts to extrude the trigger push rods 25, the trigger push rods 25 press and extrude the sliding ring 30, so that the sliding ring 30 slides along the extrusion pipe 9, therefore, one end of the extrusion pipe 9 with the conical surface 24 is contacted with the conical surface formed by the inner wall surface of the adjusting block 48 in the adjusting module 4, the adjusting block 48 is locked, at the moment, the sliding ring 30 slides relative to the extrusion pipe 9, the extrusion pipe 9 is not driven to move by the first spring 21, and the first spring 21 is stretched; the sliding ring 30 slides to drive the second push plate 31 installed thereon to slide, the second push plate 31 slides to push the corresponding third push plate 41 to slide, the third push plate 41 slides to drive the corresponding first rack 12 to slide, the first rack 12 slides to drive the first gear 42 to rotate, the first gear 42 rotates to drive the second gear 43 to rotate, the second gear 43 rotates to drive the second rack 44 to move, the second rack 44 moves to drive the toothed ring 52 to rotate, the toothed ring 52 rotates to drive the threaded sleeve 53 to rotate, during the rotation of the threaded sleeve 53, when the internal thread notch area 51 on the threaded sleeve 53 is matched with the external thread area at the upper end of the sliding rod 46, the threaded matching between the threaded sleeve 53 and the sliding rod 46 is released, at this time, the aluminum material is also extruded to the tail end, the locking mechanism 23 loses the locking function on the adjusting block 48, the extrusion push rod 2 stops pushing, at this time, the hydraulic rod 7 is controlled to work, so that the hydraulic rod 7 pushes the first push plate 22 to slide, the first push plate 22 drives the extrusion pipe 9 to slide, the extrusion rod slides to extrude the adjusting block 48 through the upper conical surface 24 of the extrusion rod, so that the adjusting block 48 moves towards the inner side of the installation chute 37 until the adjusting block completely slides into the installation chute 37, and then the extrusion push rod 2 continues to push the aluminum material to be extruded and formed; the extrusion resistance when the aluminum material terminal of the present invention is extruded is the same as that when it is extruded by the conventional extruder, and is not decreased.

After the completion, the hydraulic push rod is controlled to reset, the extrusion pipe 9 is controlled to reset through the hydraulic rod 7, the sliding ring 30, the trigger push rod 25 and the second push plate 31 which are installed on the sliding ring reset under the action of the first spring 21, the adjusting block 48 resets under the action of the second spring 49, then the pull ring 45 is manually pushed, so that the pull ring 45 drives the second rack 44 to slide, the second rack 44 slides to drive the first rack 12 to reset through the first gear 42 and the second gear 43, and the first rack 12 drives the third push plate 41 to reset.
