[0028] As a further illustration of this embodiment, the upper seat 32 is the main part of the upper mold unit 3, and its structure is firm and stable. The well-designed guide groove 38 at the lower part not only provides installation space for the screw 37, the first slide 33 and the second slide 34, but also ensures their precise guidance during movement. When the first motor 35 is started, it can provide stable power to rotate the screw 37 at a predetermined speed and direction. The punching assembly is the core part for performing the punching operation. The reaming assembly, which has a similar structure to the punching assembly, is mainly used for performing the reaming operation. The screw 37 is connected to the first slide 33 and the second slide 34 by threaded transmission, ensuring the stability and accuracy of the punching and reaming operations. When the screw 37 rotates, the first slide 33 and the second slide 34 can slide left and right along the guide groove 38, switch the punching head 31 and the reaming head 36 to align with the lower mold unit 2, and perform the punching and reaming operations.
