Detailed Implementation

[0010] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example

[0011] like Figures 1 to 3 As shown; a mold for high-pressure forming of a variable branch pipe diameter and branch pipe angle inside a tee pipe includes a lower mold group 1, an upper mold group 2, a mold core 5, a right punch 6, a balancing punch 7, and a left punch 8. The mold core 5 is disposed between the lower mold group 1 and the upper mold group 2. The right punch 6 and the left punch 8 are respectively disposed on both sides of the mold core 5 and used for stamping the tee pipe. The balancing punch 7 is disposed below the lower mold group 1 and used for stamping the tee pipe. The mold core 5 includes a lower mold core 9, an upper mold core 10, and a branch mold 14. Both the lower mold core 9 and the upper mold core 10 have intuitive cavities 12. The lower mold core 9 has an mounting... The branch mold 14 has a branch mold positioning hole 17. The branch mold 14 has a connecting intuitive cavity 15 that communicates with the intuitive cavity 12. The connecting intuitive cavity 15 has a branch hole 16. The lower mold group 1 and the upper mold group 2 both include a base plate 3 and a positioning plate 4. The positioning plate 4 is connected to the base plate 3. The positioning plate 4 has a positioning groove 13 that connects to the mold core 5. The positioning plate 4 in the lower mold group 1 has a forming hole 11 that cooperates with the balance punch 7 in the positioning groove 13. The lower mold core 9 and the upper mold core 10 are respectively provided with a number of mutually cooperating mold closing pins 18 and pin holes.

[0012] The lower die 1 and upper die 2 are respectively installed on the base and hydraulic head of the hydraulic press. The hydraulic head of the hydraulic press drives the upper die 2 to descend, causing the lower die core 9 and upper die core 10 of the die core 5 to close. The right punch 6, the balancing punch 7, and the left punch 8 are respectively installed on the corresponding hydraulic presses. When extruding the T-shaped pipe, the aluminum alloy pipe is placed in the intuitive cavity 12. The balancing punch 7 is inserted into the forming hole 11 and the branch hole 16 through the hydraulic press. The right punch 6 and the left punch 8 are inserted into the intuitive cavity 12 through the corresponding hydraulic presses to extrude the aluminum alloy pipe inside. The excess material of the aluminum alloy pipe enters the branch hole 16 and is formed by the branch hole 16 and the balancing punch 7. When processing T-shaped pipes of different diameters or T-shaped pipes of different branch angles, only the lower die core 9 and the upper die core 10 or the branch die 14 need to be replaced, which greatly reduces the mold production cost and mold replacement time.
