This text have designed one kind of the punched hole die being used to punch the holes on the side wall of the junction box which can divid automatically. The die consists of three parts by punching part ,dividing mechanism and holddown gear. Dividing mechanism has been the key of the design of this die which is mainly posed of ratchet wheel, runner, the pawl, the main axle, the links, and other ponents. Dividing part of the design allows the workpiece in the process of punching an accurate and automatic indexing to the successful pletion of a junction box wall uniform distribution of the 20hole of the system. At the same time the punching part and holddown gear have been designed in this text .For the punching part, female die and male die are designed to the fastchange structure because they are easy to damage. A polyurethane unloading packages is used for unloading. For the holedown gear, the pressure contact with the workpiece is designed to be in the form of rotation, so that the holedown gear can pinch the workpiece but will not hinder the workpiece from rotation.In order to detect the interference of the assembly and display visually such as its overall structure, finally the text uses the PO / E software to establishment of threedimensional model, assemble virtually and make a dynamic simulation for the die .The reasonabless and the correctness of the die’s design is verified.Key word: punched hole die dividing mechanism female die male die threedimensional modeli
