AI Technical Summary
In the existing technology, multiple convex bulges need to be produced using multiple stamping dies, which makes it difficult to adjust the product size, results in poor product size stability, and requires multiple punch presses and frequent manual intervention, increasing production errors.
A mold structure was designed, including a positioning part, a workpiece, a machining part, and a clamping part. Multiple punches are driven by a cutting tool to extrude a bulge on the inner wall of the workpiece. The cover plate and template part keep the workpiece stable, and the clamping part fixes the position of the workpiece, realizing multi-process machining on a single mold.
It enables a single mold to complete multiple processing steps, improves product dimensional stability, reduces manual intervention, lowers production errors, and simplifies equipment requirements.

Abstract
Claims
1. A mold structure characterized by, include: Positioning department; A workpiece fixedly installed at the middle position of the positioning part, the workpiece having a first end, a second end, and an inner cavity; A machining section is disposed in the inner cavity of the workpiece. The machining section has a cutting tool and a plurality of punches. The cutting tool and the plurality of punches abut against each other, and the plurality of punches abut against the inner wall of the workpiece. The inserter moves from the first end toward the second end to press the inner wall of the workpiece by the multiple punches to form multiple protrusions.
2. The mold structure of claim 1, wherein The processing unit includes three punches, and the three punches are spaced 120 degrees apart.
3. The mold structure of claim 1, wherein The positioning part includes a cover plate part and a template part. The cover plate part is fixedly connected to or abuts against the first end, and the template part slides in contact with the middle position of the outer wall of the workpiece.
4. The mold structure of claim 3, wherein A pressure plate is also fixedly connected near the first end, and the pressure plate is fixedly connected to the cover plate.
5. The mold structure of claim 3, wherein The cover plate portion and the template portion are parallel to each other.
6. The mold structure of claim 2, wherein A stripper is also fixedly installed inside the inner wall of the workpiece. The stripper has multiple cavities, and the multiple cavities correspond to multiple punches.
7. The mold structure of claim 6, wherein Each of the punches slides relative to the corresponding inner wall of the cavity.
8. The mold structure of claim 1, wherein The positioning part further includes a clamping part, which includes a plurality of clamping blocks, all of which abut against the second end.
9. The mold structure of claim 8, wherein The locations of the multiple clamping blocks correspond to the locations of the multiple convex hulls.
