If the condensed water level exceeds that of the lower shoulder and bead area, the tire will be undervulcanized, exposing it to the risk of delamination and bubbles. However, the current horizontal injection design of the cylinder head in the center mechanism of the vulcanizer is ineffective in reducing this condensed water level. Utility Model Content

Example 5

[0026] See also Figure 1 、 Figure 2 and Figure 3 A vulcanizing machine central mechanism cylinder head capable of effectively reducing the amount of condensed water is disclosed.

Example 6

[0027] See also Figure 1 、 Figure 2 and Figure 3 A vulcanizing press central mechanism cylinder head that effectively reduces condensate accumulation. Based on the technical solution described in Example 1, the cylinder head 1 has 12 drain holes 5 arranged in three outwardly extending rows, each row with four drain holes evenly distributed in a straight line.

This arrangement effectively collects and disperses water flow, ensuring even distribution, reducing the possibility of blockage and water accumulation, and improving drainage efficiency.

[0028] The basic working principle of this utility model is as follows:

[0029] High-pressure steam and nitrogen enter the cavity formed by the arc-shaped extended groove of the ring seat and the arc-shaped extended groove 6 of the cylinder head 1 through the steam and nitrogen inlet pipe. Five vertical steam and nitrogen injection ports 3 disperse the spray upward, reducing the pressure on the front surface and allowing the medium to fall from the top to the bottom. Water is retained along the sides of the bladder by gravity. Six lateral steam and nitrogen injection ports 7 inject steam and nitrogen diagonally downward from different directions. The steam and nitrogen ejected from the nozzles can directly reach the lowest area of ​​the lower mold, stirring the condensed water at the bottom of the bladder and stirring it into an annular vortex. It enters the drain hole 5 of the cylinder head 1, and then flows through the funnel-shaped collection to the drain pipe. After this process, the amount of condensed water in the bladder is effectively reduced, minimizing its adverse effects on tire vulcanization.
