[0020] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0021] like Figures 1 to 3 The U-shaped package welding mold shown includes an upper plate 4; the upper plate 4 is provided with a positioning groove for positioning the U-shaped package diode during firing.

[0022] There are multiple positioning grooves, which are staggered on the left and right.

[0023] A lower plate 5 is fixed to the bottom of the upper plate 4 .

[0024] The upper plate 4 and the lower plate 5 are fixed by screws 6 .

[0025] The screw 6 is located between every two positioning grooves.

[0026] The screws 6 are located near the left and right sides.

[0027] The positioning grooves are composed of an electrode positioning groove 1, a tube body positioning groove 2, and a lead positioning groove 3.

[0028] The tube body positioning grooves 2 are located on both sides of the electrode positioning grooves 1 , and the lead wire positioning grooves 3 are located on both sides of the tube body positioning grooves 2 .

[0029] The lead wire positioning groove 3 extends to the outside of the side edge of the upper plate 4 .

[0030] The upper plate 4 is made of alloy aluminum; the lower plate 5 is made of alloy aluminum.

[0031] The electrode positioning groove 1 is used to position the electrode sheet. Its width is about 0.05-0.1 mm wider than the thickness of the electrode sheet. When the mold is installed, there is a small gap between the electrode sheet and the electrode sheet can be easily placed in, which well ensures the size accuracy and position accuracy of the electrode sheet.

[0032] The tube body positioning groove 2 is used to position the tube body. The length and width ensure that the tube body can be easily inserted without leaving a large gap, thus ensuring the verticality of the tube body, electrode sheet and lead wire, avoiding skew during the firing process, thereby ensuring the consistency of the entire product.

[0033] The lead wire positioning grooves 3 are used for positioning the lead wires. The two lead wire positioning grooves 3 are perpendicular to the tube body positioning grooves 2 to prevent the lead wires from being skewed during the firing process.

[0034] Since the grooves of each lead are opened to the edge, the U-shaped packaged diode requires high temperature during firing. In order to prevent the upper plate from deforming and ensure the size and shape accuracy of the diode, screws are used to fix it on both sides of the groove.

[0035] Thus, the present invention:

[0036] ① The upper and lower plates are made of alloy aluminum. The entire mold is simple and quick to process, and can be processed in batches. After being assembled with screws, it can be used all the time;

[0037] ② The U-shaped packaged diode can be fired in one go, which ensures the size and shape accuracy of the tube body;

[0038] ③ In the upper plate part, by processing different sizes of the electrode positioning groove 1, the tube body positioning groove 2, and the lead positioning groove 3, the firing requirements of various models of U-shaped packaged diodes can be met.
