Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a shoelace head processing mold. Background Art

[0002] In order to prevent the threads at both ends of the shoelace from unraveling and to facilitate the shoelace to be threaded through the shoelace holes on the shoes, shoelace heads with a diameter smaller than the shoelace body are provided at both ends of the shoelace. The shoelace heads are made of plastic or metal. Currently, metal shoelace heads are all processed by punching machines.

[0003] For example, a shoelace head processing mold with patent number CN214442351U includes an upper mold and a lower mold, wherein the upper mold is provided with a side tooth forming head, and the lower mold is provided with a side tooth forming groove matching the size of the side tooth forming head for the side tooth forming head to be inserted, the upper mold is provided with a positioning hole forming column, and the lower mold is provided with a column groove for the positioning hole forming column to be inserted, the upper mold is provided with a cutting head, and the lower mold is provided with a cutting groove for the cutting head to be inserted. The above documents still have shortcomings. When in use, the mold is designed to directly cut off the thin plate, and the thin plate is formed by single-sided cutting. Compared with the traditional one-time stamping, the generation of waste between the thin plates is avoided, and the reduction of 20 compared with the traditional % of waste, saving material costs. Single-sided cutting of the thin plate will only produce single-sided burrs, which reduces the generation of burrs compared to one-time stamping.

When the shoelace head processing mold in the above document is used to process the shoelace head, it is not convenient to pre-roll the metal plate for shoelace head processing. At the same time, if the metal plate for shoelace head processing is offset during placement, it will affect the processing effect of the shoelace head.
