It is ejected from the micro air outlet to neutralize the static electricity on the waste material and the punch. The ion air directly reaches the interior of the punch to eliminate static electricity. The waste material ejector also serves as an ion jet channel. The waste material ejector pushes the waste material onto the punched parts.

[0023] The working principle of the mold for eliminating static electricity at the end of a punch in a vehicle connector metal terminal provided by this utility model is as follows: First, the workpiece to be processed is placed on the fixed mold 43, which is slidably installed in the fixed mold mounting groove 41 at the upper middle of the operating table 1; after the equipment is started, the solenoid valve 42 embedded in the fixed mold mounting groove 41 is energized, which adsorbs and fixes the fixed mold 43; at the same time, the negative pressure fan 35 of the negative pressure waste collection assembly 3 starts to run, and at this time the solenoid valve inside the feed pipe 31 is usually in the closed state, so that a negative pressure environment is formed in the negative pressure box 32; then, the mold... The output end of the hydraulic press 45 of component 4 pushes the connecting plate 46 downward, causing the four connecting rods 47 to slide downward along the fixed plate 48, thereby driving the punch fixing plate 49 and the punch 410 at its lower center to move downward for punching. The limiting fixing plates 412 at the lower ends of the damping rods 411 on both sides of the punch 410 move downward synchronously and slide along the inner side of the fixed mold 43 to constrain the position of the workpiece. The damping rods 411 buffer the impact vibration. During the punching process, the ion generator 51 of the electrostatic elimination component 5 is also activated to generate ion wind. The generated ionized air is conveyed through the conveying pipe 52 to the limiting and fixing pipe 53, and then enters the interior of the waste ejector head 55 through the movable pipe 54 slidably connected to it. Finally, it is ejected from the micro air outlet 56 on the outside of the waste ejector head 55, enveloping the punch 410 area to neutralize the generated static charge. At this time, the spring 510, which is sleeved on the outside of the movable pipe 54 and located between the circular limiting plate 58 and the spring limiting cylinder 59, releases its elastic force, pushing the waste ejector head 55 downward relative to the punch 410, ejecting the waste generated by stamping from the workpiece or mold cavity; immediately afterwards The solenoid valve inside the feed pipe 31 is opened, and the negative pressure fan 35 runs continuously. The ejected waste material is sucked into the feed pipe 31 under negative pressure, enters the negative pressure box 32, and finally falls into the waste storage box 33 at its front end for collection. After the waste material is collected, the solenoid valve of the feed pipe 31 is closed. The operator can then take out the processed workpiece. When it is necessary to change the mold, the power of the solenoid valve 42 is disconnected to release the adsorption, and the fixed mold 43 can be slid out from the fixed mold mounting slot 41 for replacement. The accumulated waste material in the waste storage box 33 should be cleaned regularly.

[0024] It is worth noting that the input terminals of the negative pressure fan 35, solenoid valve 42, hydraulic press 45 and ion generator 51 disclosed in the above embodiments are electrically connected to the output terminal of an external power supply through an external PLC controller. The external PLC controller controls the operation of the negative pressure fan 35, solenoid valve 42, hydraulic press 45 and ion generator 51 using methods commonly used in the prior art.
