[0028] As shown in Figure 1 and Figure 2 The utility model discloses a kind of electrode post wafer type cap back cutting moulds, including the main mould plate 1 and the die plate 2 of opposite arrangement, the main components of the above-mentioned utility model will be specifically described as follows:

[0029] As Figure 1 , Figure 2 and Figure 3 shown, the upper end of the main template 1 is provided with a trimming die core 11, the trimming die core 11 is provided with an inner cutting hole 11a, the inner cutting hole 11a is slidably connected with a main mold push tube 12, the rear end of the main mold push tube 12 is provided with an empty slot 13 between the main template 1, the bottom of the empty slot 13 is connected with the bottom of the main mold push tube 12 through a spring 14, the main mold push tube 12 is provided with a positioning hole 12a for positioning and arranging the electrode column 100, and the positioning hole 12a is slidably connected with a top rod 15.

[0030] As Figure 1 , Figure 2 and Figure 3 shown, the die plate 2 is provided with a cutting bar 21 at the position corresponding to the inner cutting hole 11a, and the cutting bar 21 is provided with a cutting bar 21, and the cutting bar 21 is provided with a cutting bar 21.

[0031] Referring to Figure 1 , Figure 2 and Figure 3 shown, the utility model uses the following method and principle: when the punching operation is carried out, the top rod 15 moves backward, and the electrode column 100 is arranged in the positioning hole 12a; then the die plate 2 moves downward to carry out the punching operation, and the inner cutting hole 11a and the cutting bar 21 are aligned with the edge of the head sheet type cap 101 of the electrode column 100 during punching; the front end of the cutting bar 21 presses the sheet type cap 101 and presses downward, and in this process, the pressure on the front end of the main mold push tube 12 is greater than the thrust of the spring 14, so that the electrode column 100, the sheet type cap 101 and the main mold push tube 12 move downward along the inner cutting hole 11a, the cutting bar 21 and the cutting bar 21 are cut off, the cutting bar 21 is cut off, and the cutting bar 21 is cut off. The cutting process, because the sheet type cap 101 moves with the main mold push tube 12, the extrusion force received by the sheet type cap 101 is greatly reduced, thereby protecting the flatness of the sheet type cap 101, and the sheet type cap 101 is cut off simultaneously from the upper and lower sides, so that burrs are not easily generated at the edge of the sheet type cap 101; after the punching is completed, the excess waste is cut off by the cutting bar 21, and then the excess waste is separated from the cutting bar 21 through the ejection mechanism 23, so that the operator can clean up conveniently.

[0032] As Figure 1 , Figure 2 and Figure 3To ensure the cleaning efficiency of the waste material, the ejection mechanism 23 includes a first push plate 23a arranged at the rear end of the die push tube 22, the first push plate 23a being sleeved on the outer periphery of the cutting rod 21 in a slidable manner, the rear end of the first push plate 23a being connected with a ejector pin 23b, the ejector pin 23b being connected with a second push plate 23c through the rear end of the die plate 2, the rear end of the die plate 2 being provided with a guide groove 24, and the outer periphery of the second push plate 23c being slidably connected with the sidewall of the guide groove 24.

[0033] As shown in Figure 1 , Figure 2 and Figure 3 , to improve the movement stability of the ejection mechanism, the ejector pin 23b is provided with three, and the three ejector pins 23b are uniformly arranged along the circumference of the first push plate 23a.

[0034] As shown in Figure 1 , Figure 2 and Figure 3 , to improve the service life of the ejection mechanism, a protective pad 23d is arranged between the second push plate 23b and the bottom of the guide groove 24, and the three ejector pins 23b are slidably connected with the protective pad 23d.

[0035] As shown in Figure 1 , Figure 2 and Figure 3 , to facilitate the disassembly and assembly of the mold, the bottom of the clearance groove 13 is detachably provided with a tooth cover 16, and the ejector rod 15 is slidably connected with the tooth cover 16.

[0036] As shown in Figure 1 , Figure 2 and Figure 3 , to improve the service life of the mold, the outer diameter of the cutting rod 21 is 0.03-0.05mm smaller than the inner diameter of the inner cutting hole 11a, so that a gap is left between the two, which avoids friction and collision between the two without affecting the punching effect.

[0037] As shown in Figure 1 , Figure 2 and Figure 3 , to facilitate the installation, debugging and adjustment of the mold, the front end surface of the main mold push tube 12 is 2-3mm higher than the front end surface of the trimming mold core 11 after the main mold push tube 12 is reset.

[0038] Finally, it should be pointed out that the above is only a preferred embodiment of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement of some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
