The fifth assembly plate 219 has a through groove inside. The second thrust spring 222 passes through the through groove and is positioned between the fourth assembly plate 218 and the sixth assembly plate 224. The through groove restricts the position of the second thrust spring 222, preventing it from disengaging and affecting the sliding of the sixth assembly plate 224 and the ejector core 213. The fifth assembly plate 219 has a placement groove at the relative position of the sliding rod 220. The sliding rod 220 is positioned inside the placement groove. The placement groove restricts the position of the sliding rod 220 while preventing the sliding rod 220 from protruding and affecting the assembly of the fifth assembly plate 219 and the fifth fastening bolt 221.

[0027] During operation, after aligning the threaded hole of the base plate 215 with the through holes of the third assembly plate 216 and the first assembly plate 21, the fourth fastening bolt 217 is threaded through the through hole and connected to the base plate 215. Then, after aligning the through holes of the limiting cylinder 227 and the connecting cylinder 229 with the corresponding threaded holes on the first assembly plate 21, the eighth fastening bolt 228 is threaded through the through hole of the limiting cylinder 227, and the ninth fastening bolt 230 is threaded through the through hole of the connecting cylinder 229 to complete the assembly of the lower half of the mold. Next, the upper half is assembled. Then, after aligning the threaded hole of the ejector core 213 with the through hole of the sixth assembly plate 224, the third fastening bolt 214 is threaded through the third fastening bolt 214 and connected to the ejector core 216. 3. Threaded connection: Align the lower threaded hole of the sixth assembly plate 224 with the through hole on the sixth assembly plate 224. Thread the seventh fastening bolt 226 through the second assembly plate 210 and thread it onto the connecting sleeve 223. Align the upper threaded hole of the connecting sleeve 223 with the through hole of the fifth assembly plate 219. Thread the sixth fastening bolt 225 through the fifth assembly plate 219. Place the sliding rod 220 inside the receiving groove of the fifth assembly plate 219. Align the threaded groove of the fifth assembly plate 219 with the through hole of the fourth assembly plate 218. Thread the fifth fastening bolt 221 through the through hole of the fourth assembly plate 218 and thread it onto the fifth assembly plate 219. This completes the mold assembly.

[0028] After assembling the mold, the sheet metal is placed on the first stamping base 22. When the second assembly plate 210 is pressed down, the internal through hole contacts the first stamping base 22, thereby trimming the material. After rough stamping, the second assembly plate 210 continues to press down, causing the push block 211 to contact the chamfer of the first connecting block 24, pushing the first connecting block 24 to slide inward. When the first connecting block 24 slides, it cooperates with the second connecting block 27, causing the fine stamping mold plate body 29 to be lifted up, and then cooperates with the ejector core 213. After the fine blanking of the material is completed, the mold rises, and the first thrust spring 26 provides a thrust to the first connecting rod 25, pushing the first connecting block 24 to slide outward, causing the fine blanking die plate body 29 to retract. The second thrust spring 222 provides a thrust to the sixth assembly plate 224, causing the sixth assembly plate 224 to slide downward. The downward sliding of the sixth assembly plate 224 causes the ejector core 213 to slide inside the punching hole of the second assembly plate 210, causing it to slide out of the punching hole, thus making it easier for the staff to pick up.

[0029] Through the above steps, compared to the traditional method of separating rough and fine stamping, stamping is performed by contacting the first stamping base 22 with the second assembly plate 210, and fine stamping is performed by lifting the fine stamping die plate body 29. This solves the problem that the method of performing rough and fine stamping separately by two machine tools is too cumbersome and reduces production capacity when processing some special irregular parts.
