[0042] As shown in Figure 3 , a cutting die mainly applied to cutting of connecting terminals, as shown in Figure 1 and Figure 2 , the connecting terminal cutting device comprises an upper die set 100, a lower die set 200, a jacking assembly 400 for driving the upper die set 100 to descend and a lifting assembly 300 for driving the lower die set 200 to lift, the lower surface of the upper die set 100 is provided with an upper die 10, the upper surface of the lower die set 200 is provided with an upper die 10, the upper die 10 and the lower die 20 are die sets of the connecting terminal cutting device, as shown in Figure 3 , a guide rod 30 is further installed between the upper die 10 and the lower die 20, as shown in Figure 3 , Figure 4 and Figure 5 , a through material taking groove 16 is formed in the upper die 10, an upper cutter 14 is installed on the upper die 10, the upper cutter 14 is located on the left side of the material taking groove 16, an installation groove 15 is formed in the upper die 10, the installation groove 15 is located on the right side of the material taking groove 16, and the installation groove 15 is communicated with the material taking groove 16, a rotatable cam material pressing block 13 is installed in the installation groove 15, as shown in Figure 6 and Figure 7As shown, the cam pressure block 13 includes a lever 131. The head of the lever 131 is equipped with a pressure head 133 made of soft material. A rotating shaft 135 is located at the bottom corner of the lever 131. Both ends of the rotating shaft 135 are rotatably mounted on the upper mold core 10. An inwardly recessed groove 136 is also formed on the inner side of the lever 131. The rotating shaft 135 passes through the groove 136. A torsion spring 134 is also mounted on the rotating shaft 135 located within the groove 136. One torsion arm of the torsion spring 134 abuts against the bottom of the groove 136, and the other torsion arm abuts against the side wall of the mounting groove 15. A rotatable roller 132 is mounted at the tail of the lever 131. Figure 8 , Figure 9 and Figure 10 As shown, a lower die core 20 is equipped with a lower cutter 24 that cooperates with the upper cutter 14 for cutting. A cam pusher 23, which rotates the cam pressure block 13, is also installed on the lower die core 20. The cam pusher 23 is located on one side of the lower cutter 24. Figure 4 and Figure 5 As shown, the upper mold core 10 has an insertion hole for inserting the cam ejector rod 23 into the mounting slot 15, such as... Figure 5 As shown, when the upper mold core 10 and the lower mold core 20 are closed, the cam ejector 23 is inserted into the mounting slot 15 from the insertion hole. When the cam ejector 23 contacts the roller 132, the cam ejector 23 applies a pushing force to the roller 132, thereby causing the lever 131 to rotate around the rotating shaft 135, which in turn causes the pressure head 133 to press against the middle of the connecting terminal. While the lever 131 rotates, the torsion spring 134 generates torque. When the upper mold core 10 and the lower mold core 20 are demolded, the lever 131 returns to its original position under the action of the torsion spring 134. In this embodiment, as... Figure 4 As shown, a stop surface is provided on the mounting groove 15. When the lever contacts the stop surface under the torque of the torsion spring 134, the lever 131 is completely located within the mounting groove 15. During the mold closing process, when the pressure head 133 contacts the middle of the connecting terminal, the pressure head 133 presses against the connecting terminal. Then, as the upper mold core 10 and the lower mold core 20 close, the pressure head 133 deforms. Preferably, the pressure head 133 is made of rubber or silicone. Through the deformation and compression of the pressure head 133, the pressure head 133 can continuously apply pressure to the connecting terminal, ensuring the clamping force of the connecting terminal. Then, when the upper cutter 14 and the lower mold core 20 close, the pressure head 133 deforms. The lower cutter 24 then moves relative to the material strip, thereby separating the connecting terminal from the material strip and achieving cutting. Since the connecting terminal is pressed during the cutting process, the connecting terminal will not vibrate during the cutting process, thus ensuring the cutting quality of the connecting terminal. Moreover, during demolding, since the pressure head 133 is made of soft material, the pressure of the pressure head 133 on the connecting terminal gradually decreases, thus preventing the connecting terminal from suddenly losing pressure and ensuring that the connecting terminal does not vibrate. This avoids collisions with the connecting terminal, ensures that the position of the connecting terminal is fixed, and facilitates the gripping of the connecting terminal.

[0043] In the embodiment, as shown in Figure 5 When the pressure head 133 contacts the connector middle part, the upper die set 100 continues to go down as the mold closes, preferably, before the mold closes, the roller 132 rolls from the top of the cam ejector pin 23 to the sidewall of the cam ejector pin 23, at this time, although the upper die set 100 goes down, the roller 132 has rolled to the sidewall of the cam ejector pin 23, the pressure of the pressure head 133 on the connecting terminal remains constant, thereby avoiding the pressure head 133 from damaging the connecting terminal, while avoiding the pressure head 133 from deforming too much to cause damage, ensuring the service life of the pressure head 133.

[0044] In the embodiment, as shown in Figure 4 and Figure 5 The upper die set 10 includes a first plate body 11 and a second plate body 12 which are detachably connected, preferably, the first plate body 11 and the second plate body 12 are detachably connected through locking screws, the upper cutter 14 is installed between the first plate body 11 and the second plate body 12, and the cutting edge of the upper cutter 14 protrudes from the lower surface of the second plate body 12, further, as shown in Figure 12 The top of the upper cutter 14 is provided with a limiting block 141, the two sides of the upper cutter 14 are provided with protrusions 142, a limiting slot matched with the protrusions 142 and a slot matched with the upper cutter 14 are formed on the second plate body 12, and a recess corresponding to the limiting block 141 is formed on the bottom of the first plate body 11, when the first plate body 11 and the second plate body 12 are installed, the limiting block 141 is clamped in the recess, and the protrusions 142 are clamped in the limiting slot, thereby avoiding the relative displacement between the upper cutter 14 and the upper die set 10.

[0045] In the embodiment, as shown in Figure 4 and Figure 5 The contact surfaces of the first plate body 11 and the second plate body 12 are both provided with recesses, and the two recesses form an installation slot 15, the second plate body 12 is provided with a plug hole for the cam ejector pin 23 to insert, further, as shown in Figure 13 The recess on the second plate body 12 is a through slot in the up-down direction, then the bottom of the recess is covered by a cover plate 19, the plug hole is formed on the cover plate 19, and the cover plate 19 and the second plate body 12 are locked through locking screws, when the cover plate 19 is installed, the cover plate 19 does not protrude from the lower surface of the second plate body 12, and the corresponding torsion arm of the torsion spring 134 abuts against the cover plate 19.

[0046] In the embodiment, as shown in Figure 8 and Figure 9As shown, the lower die core 20 comprises a detachable third plate body 21 and a fourth plate body 22, the third plate body 21 and the fourth plate body 22 are detachably connected through locking screws, the bottom of the lower cutter 24 and the cam ejector rod 23 are mounted between the third plate body 21 and the fourth plate body 22, the third plate body 21 is provided with a blanking groove 25, the blanking groove 25 extends downward and penetrates through the fourth plate body 22, and the protruding part of the upper cutter 14 can be inserted into the blanking groove 25, so that when the mold is closed, the upper cutter 14 enters the blanking groove 25, and the cutting end of the connecting terminal is received by the lower cutter 24, thereby avoiding deformation of the cutting end of the connecting terminal.

[0047] In this embodiment, as shown in Figure 9 and Figure 10 , the third plate body 21 is provided with a notch near the blanking groove 25, the two side walls of the notch are provided with insertion grooves 215, and the lower cutter 24 is fitted in the notch, as shown in Figure 11 , the lower cutter 24 is provided with clamping blocks 241 on both sides which cooperate with the insertion grooves 215, and the upper surface of the lower cutter 24 is provided with a storage groove 243 on the side away from the blade edge, as shown in Figure 10 , the upper surface of the third plate body 21 is provided with a receiving groove 212, the receiving groove 212 communicates with the storage groove 243, the side wall of the receiving groove 212 near the storage groove 243 is a slope surface 213, and a plurality of partition blocks 214 are arranged on the slope surface 213, thereby forming a plurality of partition grooves on the slope surface 213, the bottom of the lower cutter 24 is provided with a flange 242, and the flange 242 is pressed between the third plate body 21 and the fourth plate body 22, in this embodiment, a piece of material belt has a plurality of parallel connecting terminals, before cutting, the middle part of the connecting terminal is located in the storage groove 243, the shape of the storage groove 243 is set according to the shape and size of the middle part of the connecting terminal, and the spring end part of the connecting terminal is located in the receiving groove 212, and the adjacent two connecting terminals are separated by the partition blocks 214, thereby avoiding collision between the connecting terminals, and the relative position between the two connecting terminals can be ensured during feeding, so that the spring of the connecting terminal can independently enter the corresponding partition groove.

[0048] In this embodiment, as shown in Figure 14As shown, at least two groups of elastic column bodies 18 are arranged on the upper die core 10, and at least one group of elastic column bodies 18 is arranged on the front side of the upper cutter 14, and at least one group of elastic column bodies 18 is arranged on the rear side of the material taking groove 16. The elastic column body 18 includes a stepped column, a compression spring and a plug. The second plate body 12 is provided with a stepped hole, and the stepped column is arranged in the stepped hole in a matched mode. A corresponding through hole is arranged on the first plate body 11, and the plug is arranged in the through hole. Preferably, the plug is in threaded connection with the through hole. The compression spring is compressed between the stepped column and the plug. When the mold is closed, the elastic column body 18 presses the material belt, so that the material belt does not move, thereby ensuring the connection of the terminal end of the terminal. Preferably, each group of elastic column bodies 18 has two, so that when the mold is closed, the four corners of the material belt can be pressed, thereby avoiding the movement of the material belt, and ensuring the cutting quality of the connection terminal.

[0049] In the embodiment, since the connection terminal and the material belt are not in the same horizontal dimension, it is difficult to realize the feeding of the connection terminal during the horizontal movement of the material belt. Further, as shown in the prior art, Figure 15 As shown, the lifting assembly 300 includes a base 500 and a translation cylinder 301. The translation cylinder 301 is arranged on the base 500. The top of the base 500 is provided with a pair of guide grooves 304 extending along the left-right direction. A sliding rail 303 is slidably arranged in the guide groove 304. One end of the sliding rail 303 is connected with a moving plate 302. The extension shaft of the translation cylinder 301 is connected with the moving plate 302. The sliding rail 303 is provided with a climbing slope 305. The front and rear side walls of the lower die core 20 are both provided with a side plate 202. The side plate 202 is provided with a rolling body 203. When the sliding rail 303 moves left and right, the rolling body 203 rolls along the surface of the sliding rail 303. Since the sliding rail 303 has the climbing slope 305, the sliding rail 303 has an upper rail surface and a lower rail surface. When the rolling body 203 moves from the lower rail surface to the upper rail surface, the lower die set 200 rises. When the rolling body 203 moves from the upper rail surface to the lower rail surface, the lower die set 200 falls. Therefore, when feeding, the rolling body 203 is located on the lower rail surface, and at this time, the lower die set 200 is in the downstroke, thereby making the lower die core 20 away from the material belt, so as to provide space for the front and rear movement of the connection terminal. When the material belt drives the connection terminal into the cutting station, the translation cylinder 301 works, so that the rolling body 203 moves from the lower rail surface to the upper rail surface. At this time, the lower die set 200 rises, thereby making the middle part of the connection terminal into the storage groove 243, and the elastic piece of the connection terminal is located in the separation groove, so as to realize the continuous feeding of the material belt driving the connection terminal, and ensure the cutting efficiency of the connection terminal.
