For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the utility model provides a technical solution for a graphite mold suitable for welding high-power special-shaped gas discharge tubes: it includes an upper mold, a middle mold and a lower mold, and heating electrode positioning holes 1 are provided on the edges of both sides of the upper mold, the middle mold and the lower mold. A plurality of equalizing holes 3 are provided on the adjacent sides of the heating electrode positioning hole 1, and a plurality of lower mold assembly areas 4 are provided between the equalizing holes 3 on the lower mold, and a temperature monitoring hole 6 is installed at the edge.

A plurality of electrode second lead-out holes 9 are provided on the upper mold, and the plurality of electrode second lead-out holes 9 correspond one-to-one to the middle mold assembly areas 7.

[0027] Among them, positioning bosses 5 are installed on the lower mold and the middle mold, and positioning holes 8 that are compatible with the positioning bosses 5 are provided on the lower mold, the middle mold and the upper mold.

[0028] Among them, a plurality of fixing holes 2 are provided at the edges of the upper mold, the lower mold and the middle mold for fixing the mold.

[0029] Among them, the lower mold assembly area 4 is composed of the upper area 41 of the lower mold assembly area, the middle area 42 of the lower mold assembly area and the lower area 43 of the lower mold assembly area. The upper area 41 of the lower mold assembly area, the middle area 42 of the lower mold assembly area and the lower area 43 of the lower mold assembly area are distributed in a high and low stepped manner. The lower area 43 of the lower mold assembly area is used to place electrode 2, the middle area 42 of the lower mold assembly area is used to place the porcelain tube, and the upper area 41 of the lower mold assembly area is used to place electrode 1.

[0030] The middle mold assembly area 7 is composed of an upper middle mold assembly area 71, a middle middle mold assembly area 72 and a lower middle mold assembly area 73. The upper middle mold assembly area 71, the middle middle mold assembly area 72 and the lower middle mold assembly area 73 are distributed in a high and low stepped manner. The lower middle mold assembly area 73 is used to place electrode 1, the middle middle mold assembly area 72 is used to place the porcelain tube, and the upper middle mold assembly area 71 is used to place electrode 2.

[0031] The working principle and usage process of this utility model are as follows: First, electrode 1, the porcelain tube, and electrode 2 are placed in the upper area 41, the middle area 42, and the lower area 43 of the lower mold assembly area in a predetermined order.

Before welding begins, the temperature of the welding area is monitored in real time through the temperature monitoring hole 6 to ensure that the temperature during the welding process is controlled within the optimal range.

[0033] During welding, the electrode is heated through the heating electrode positioning hole 1, and the heat is evenly distributed using the flow equalization hole 3, thus achieving high-quality welding results. The stepped layout of the lower and middle mold assembly areas ensures more uniform heat distribution during welding, helping to reduce welding defects and improve welding quality.

[0034] After welding is complete, the mold is disassembled and the welded workpiece removed. Thanks to the sophisticated and rational mold design, the entire welding process is both fast and efficient, significantly improving production efficiency. Furthermore, the mold's versatility and flexibility allow it to accommodate welding of gas discharge tubes of varying shapes, meeting diverse production needs.
