[0032] A cavity of a riser is formed between the Haversian block 2 , the gate mold core 1 , and the core 6 . The top of the riser formed by the cavity can be bent to form a sealing plug 23 or the sealing plug 23 can be formed by welding a pressing sheet 24 .

[0033] The mold cavity includes a bending portion molding cavity 7, a first plug receiving portion molding cavity 8, a first tube neck molding cavity 9 and a first tube body molding cavity 10 which are arranged in sequence from the gate mold core 1 to the core 6. The bending portion molding cavity 7 and the first plug receiving portion molding cavity 8 form a stepped hole structure. The bending portion molding cavity 7 and the first plug receiving portion molding cavity 8 are formed by the first end surface of the gate mold core 1 and the part of the Havers block 2 close to the gate mold core 1.

[0034] The first tube neck forming cavity 9 and the first tube body forming cavity 10 are formed by the core 6 and the Haversian block 2 .

[0035] The bottom of the first rubber plug accommodating portion molding cavity 8 is provided with an upwardly convex annular platform forming groove.

[0036] Among them, this embodiment is used to produce a bent and welded single vertical tube, which includes a bent portion 15, a first rubber plug receiving portion 16, a first tube neck 17 and a first tube body 18 arranged in sequence along the axial direction. The first rubber plug receiving portion 16 is used to install the rubber plug 23 and make the rubber plug 23 seal the first tube neck 17 and the first tube body 18. After the rubber plug 23 is installed in the first rubber plug receiving portion 16, the bent portion 15 is bent inward (radially toward the center of the circle) to press the top of the rubber plug 23 to complete the fixing of the rubber plug 23. Among them, an annular platform (the annular platform is formed by a groove formed by the annular platform) is provided at the bottom of the first rubber plug receiving portion 16, and the annular platform is used to limit the position of the rubber plug 23 to ensure that the rubber plug 23 seals the first tube neck 17.

[0037] When the mold is used, glue is injected into the cavity through the glue injection port of the gate mold core 1, and a single vertical tube before bending is obtained after injection molding. When the single vertical tube is assembled, the rubber plug 23 is placed in the first rubber plug receiving portion 16 and the above steps are followed.

[0038] The single vertical tube formed by the utility model can directly bend the bending portion 15 inwards to press and fix the rubber plug 23. The rubber plug 23 and the single vertical tube are assembled quickly, thereby improving the production efficiency of the single vertical tube. At the same time, there is no need for cumbersome welding or bonding fixation. The rubber plug 23 is squeezed and deformed to automatically seal the opening of the first rubber plug accommodating portion 16 and the first tube neck 17, and the sealing effect is good.

[0039] Embodiment 2:

[0040] like Figure 5-Figure 8As shown, the difference between this embodiment and embodiment 1 is that the mold cavity includes a tablet support molding cavity 11, a second plug accommodating portion molding cavity 12, a second tube neck molding cavity 13 and a second tube body molding cavity 14 which are sequentially arranged from the gate mold core 1 to the core 6, and the tablet support molding cavity 11 and the second plug accommodating portion molding cavity 12 form an inverted "X" structure, and the tablet support molding cavity 11 and the second plug accommodating portion molding cavity 12 are formed by the gate mold core 1 and the Havers block 2;

[0041] The second tube neck molding cavity 13 and the second tube body molding cavity 14 are formed by the core 6 and the Haversian block 2 .

[0042] The outer wall of the first tube neck forming cavity 9 and the outer wall of the first rubber plug accommodating portion forming cavity 8 form a truncated cone structure.

[0043] The outer diameter of the tablet support molding cavity 11 is larger than the outer diameter of the second plug accommodating portion molding cavity 12 . The outer diameter of the second plug accommodating portion molding cavity 12 is larger than the outer diameter of the second tube neck 21 molding cavity. The second neck molding cavity is cylindrical.

[0044] A convex sealing platform forming groove is provided on the top of the tablet pressing support forming cavity 11 .

[0045] The cross section of the sealing platform forming groove is triangular.

[0046] Among them, this embodiment is used to produce a single vertical tube with a press sheet 24 welded, and the single vertical tube with a press sheet welded includes a press sheet support portion 19, a second rubber plug accommodating portion 20, a second tube neck 21, and a second tube body 22 arranged in sequence along the axial direction. The second rubber plug accommodating portion 20 is used to install the rubber plug 23 and make the rubber plug 23 seal the second tube neck 21 and the second tube body 22. After the rubber plug 23 is installed in the second rubber plug accommodating portion 20, the press sheet 24 is welded and bonded to the press sheet 24 support portion 19, and the press sheet 24 is pressed against the rubber plug 23, thereby completing the fixing of the rubber plug 23. Among them, an annular platform (the annular platform is formed by a groove formed by the annular platform) is provided at the bottom of the second rubber plug accommodating portion 20, and the annular platform is used to limit the position of the rubber plug 23 to ensure that the rubber plug 23 seals the second tube neck 21.
