[0002] Die stamping is a crucial processing technology in modern manufacturing, widely used in numerous fields such as automobile manufacturing, electronic equipment production, and aerospace. In automobile manufacturing, a large portion of the various sheet metal parts for the car body, such as doors, hoods, and roofs, are formed using die stamping. In electronic equipment production, the metal casings and some internal metal structural components of products like mobile phones and computers also rely on die stamping to ensure their shape accuracy and dimensional consistency. This processing method can efficiently and quickly process sheet metal into various complex shapes, meeting the demands of large-scale production.
[0003] The existing positioning mechanisms used in die stamping are not convenient for users to adjust the positioning according to the size of the die, and have certain limitations. It is difficult to ensure accurate positioning between dies. In view of this, we propose a new type of die stamping positioning mechanism to solve the above problems. Utility Model Content

The end of the rotating rod passes through the interior of the worktable and connects to the third bevel gear, and the outer surface of the third bevel gear meshes with the fourth bevel gear. The fourth bevel gear is located on the outer surface of the guide rod. The end of the guide rod is connected to the threaded rod. A clamping block is fixedly connected to the top of the threaded rod. A limiting sleeve is fitted onto the outer surface of the threaded rod, and the limiting sleeve is mounted on a mold base.
[0007] Furthermore, the workbench has a connecting groove inside, and the outer walls of the two rotating rods are fitted with sleeve shafts, which are located inside the connecting groove.
[0008] Furthermore, the mold base includes a base, a groove, a lower mold, a stop plate, and a spring. The base is fixedly connected to the middle of the worktable. The base has a groove, and the upper mold is disposed in the groove. The stop plate is slidably disposed on the front and rear sides of the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through its positioning mechanism, further utilizes a motor-driven lead screw to achieve rotation, thereby driving the first bevel gear and the second bevel gear to mesh and rotate. The third bevel gear located at the other end of the rotating rod can then mesh with the fourth bevel gear, achieving relative rotation of the guide rod. The guide rod is connected to the threaded rod, and the outer wall of the threaded rod slides against the limiting sleeve, facilitating relative clamping of the top clamping block during rotation. When used in conjunction, it can autonomously control the clamping effect on different mold sizes, ensuring accurate mold positioning and meeting requirements.
