[0021] like Figure 2 , Figure 3 , Figure 4 As shown, the lower mold 1 includes a lower mold base plate 101. Fixing holes 3 are formed through both sides of the upper surface of the lower mold base plate 101. A clearance groove 102 is formed through the middle of the upper surface of the lower mold base plate 101. Clearance holes 103 are formed through both sides of the clearance groove 102 on the upper surface of the lower mold base plate 101. A lower mold fixing plate 104 is mounted on the upper surface of the lower mold base plate 101. A slot 105 is formed on the upper surface of the lower mold fixing plate 104. A limiting groove 1 is formed on the inner wall of one end of the slot 105. 06. A lower mold forming plate 107 is installed inside the slot 105. A limiting protrusion 108 is provided on one end surface of the lower mold forming plate 107. The limiting protrusion 108 can cooperate with the limiting groove 106. A cutting groove 109 is provided in the middle of the upper surface of the lower mold forming plate 107. A punching hole 110 is provided on both sides of the upper surface of the lower mold forming plate 107 and located in the cutting groove 109. The positions of the cutting groove 109 and the punching hole 110 correspond to the positions of the clearance groove 102 and the clearance hole 103 and have the same shape.

[0022] The position of the lower mold forming plate 107 inside the slot 105 can be limited by the cooperation between the limiting protrusion 108 and the limiting groove 106, making the assembly operation of the lower mold 1 more convenient. The lower mold base plate 101 is provided with a relief groove 102 and a relief hole 103, and the waste generated after stamping and cutting will fall directly.

[0023] like Figure 5 As shown, the upper mold 2 includes an upper mold base plate 201, a cutting module 202 is installed in the middle of the surface of the upper mold base plate 201, and punching modules 203 are installed on both sides of the surface of the upper mold base plate 201 and on both sides of the cutting module 202.

They can simultaneously complete the cutting and punching of the workpiece, making the processing steps simpler and more efficient.

[0025] Working principle of a rear wheel strut punching and cutting die:

[0026] In use, the lower mold 1 is composed of a lower mold base plate 101, a lower mold fixing plate 104, and a lower mold forming plate 107. Positioning is achieved through the positioning holes 4 during assembly, ensuring greater accuracy. The positioning holes 4 also provide positioning during the closing process of the lower mold 1 and the upper mold 2, preventing positional shifts. The workpiece is passed through the through groove 5, ensuring that the punching and cutting positions are below the cutting groove 109 and the punching hole 110. After fixing the positions of both ends of the workpiece, the upper mold 2 punches the workpiece inside the lower mold 1. During the mold closing process, the cutting module 202 and the punching module 203 move to the inside of the cutting groove 109 and the punching hole 110 respectively, and then move to avoid... Inside the groove 102 and the clearance hole 103, during the downward movement, the cutting module 202 will cut the workpiece located inside the through groove 5 according to its shape. The punching module 203 can punch holes on the surface of the workpiece. The punching module 203 is symmetrically arranged on both sides of the cutting module 202. In the process of cutting the workpiece into two sections, the punching of the two cut workpieces is also completed at the same time. The cutting and punching of the workpiece can be completed at the same time using a single mold, avoiding multiple transfer, disassembly and clamping operations of the workpiece, which can effectively save processing time and improve processing efficiency. The material punched off by the cutting module 202 and the punching module 203 will fall down through the clearance groove 102 and the clearance hole 103 for easy collection.
