[0004] In order to solve the above technical problems, the technical scheme adopted by the utility model is as follows: an axial diode pre-shaping device has a base die and a pressing die. The base die is installed on a base die bracket, and the pressing die is installed on a pressing die bracket. A die closing mechanism is installed on the pressing die bracket, and the die closing mechanism can push the pressing die to close with the base die. The base die is provided with a horizontally arranged positioning groove and a vertically arranged shaping groove. The pressing die is provided with a positioning boss, and the positioning boss can be embedded into the positioning groove on the base die during die closing. Both sides of the shaping groove are guiding slopes, which are inclined from the groove opening to the groove bottom.

[0005] In the above technical scheme, the die closing mechanism includes a cylinder, a slider and a track. The pressing die bracket is installed on the slider, and the slider can move along the track under the push of the cylinder.

[0006] In the above technical scheme, the depth of the shaping groove is greater than the height of the positioning boss.

[0007] In the above technical scheme, the shaping groove is a conical groove.

[0008] In the above technical scheme, the width of the bottom of the shaping groove is 5.35 - 6.35 mm.

[0009] In the above technical scheme, the base die is provided with two shaping grooves and two positioning grooves.

[0010] In summary, the beneficial effects of adopting the technical scheme of the utility model compared with the traditional technical means are:

[0011] The utility model is applied to a vertical forming taping machine, and an additional pre-shaping process is added to the original forming mode. When in use, the pins of the diode are placed in the shaping grooves of the base mold, and the pressing mold pushes the pins to the bottom of the grooves when the mold is closed, so as to realize shaping. In this way, the two pins are parallel to each other, and the sides are also on the same line. The pins can better enter the subsequent forming mold, effectively solving the phenomenon that the pins explode after forming, effectively improving the product quality, reducing the workload of personnel, and saving costs.
