[0020] See also Figure 1-3 As shown, the utility model provides a technical solution:

[0021] Embodiment 1: A hot extrusion diverter die with a protective ring comprises an upper die 1 and a lower die 3, a core 12 is fixedly arranged in the middle of the upper die 1, a diverter hole 11 is provided in an annular array around the core 12 on the upper die 1, a diverter bridge is provided on the upper die 1 between the diverter hole 11 and the core 12, a protective ring 13 is fixedly provided on the top of the upper die 1 outside the diverter hole 11, a positioning hole 15 is provided in an annular array around the core 12 on the bottom of the upper die 1, a side groove 16 is provided in an annular array on the side wall of the upper die 1, the side groove 16 corresponds to the positioning hole 15 one by one, and the side groove 16 is connected to the positioning hole 15, and the inside of the side groove 16 is rotatably connected to the rotating shaft 6 The movable card 7 and the two ends of the rotating shaft 6 are rotatably connected to the inner wall of the side groove 16 through bearings. The movable card 7 is sleeved and fixed on the rotating shaft 6. A metal spring 8 is arranged between the pressing end of the movable card 7 and the inner wall of the side groove 16. One end of the metal spring 8 is fixedly connected to the pressing end of the movable card 7, and the other end of the metal spring 8 is fixedly connected to the inner wall of the side groove 16. An annular protrusion 14 is arranged at the edge position of the bottom of the upper mold 1. A movable sleeve 2 is movably sleeved on the upper mold 1 above the annular protrusion 14. A toggle portion 21 is symmetrically arranged on the outer wall of the movable sleeve 2. A positioning column 4 is arranged in a ring array on the top of the lower mold 3, and an outflow hole is opened in the middle of the lower mold 3. A card slot 41 is provided on the outer wall of the positioning column 4, the positioning column 4 is connected with the positioning hole 15, and the hook end of the movable card 7 is connected with the card slot 41. By moving the movable ring 2 upward along the outer wall of the upper mold 1, the pressing ends of the four movable cards 7 can be pressed synchronously, so that the hook ends of the four movable cards 7 are moved out of the card slot 41, and the positioning column 4 can be taken out from the positioning hole 15, so as to realize the rapid separation of the upper mold 1 and the lower mold 3, and the operation is more convenient. When using the hot extrusion diversion mold with the protective ring 13, the burned metal rod is loaded from the top of the upper mold 1 by the machine. The metal rod is very easy to melt under high temperature. The protective ring 13 mitigates the impact force of the metal rod on its diverter bridge and protects the diverter bridge. The molten material enters the interior of the diverter mold through the diverter hole 11 and flows out through the lower mold 3 to finally form a hollow profile. When maintenance or repair is required, it needs to be separated. The staff can manually push the toggle part 21 upward to drive the movable sleeve 2 to move upward along the outer wall of the upper mold 1, so that the pressing ends of the four movable cards 7 can be pressed synchronously to compress the metal spring 8. At this time, the hook end of the movable card 7 can be moved out of the card slot 41, so that the positioning column 4 can be taken out of the positioning hole 15, and the upper mold 1 and the lower mold 3 can be quickly separated.

[0022] Embodiment 2: The difference between this embodiment and embodiment 1 is that, a locking bolt 5 is symmetrically threaded on the movable collar 2, and one end of the locking bolt 5 abuts against the outer wall of the upper mold 1, which can lock the movable collar 2 to a certain extent and prevent the movable collar 2 from moving easily. An arc-shaped protrusion 71 is provided on the outer wall of the pressing end of the movable card 7, which can avoid direct friction between the movable collar 2 and the corners on both sides of the movable card 7, thereby better protecting the movable card 7.

[0023] Working principle: When using the hot extrusion diversion die with a protective ring 13, the burned metal rod is loaded from the top of the upper die 1 by a machine. The metal rod is very easy to melt under high temperature. The protective ring 13 alleviates the impact of the metal rod on its diversion bridge and protects the diversion bridge. The molten material enters the interior of the diversion die through the diversion hole 11 and flows out through the lower die 3 to eventually form a hollow profile. When maintenance or repair is required, it is necessary to separate them. The staff can manually push the toggle part 21 upward to drive the movable sleeve 2 to move upward along the outer wall of the upper die 1, so that the pressing ends of the four movable cards 7 can be pressed synchronously to compress the metal spring 8. At this time, the hook end of the movable card 7 can be moved out of the card slot 41, so that the positioning column 4 can be taken out of the positioning hole 15, and the upper die 1 and the lower die 3 can be quickly separated.
