Description

Technical Field

[0001] The utility model relates to the technical field of hardware molds, in particular to a high-precision hardware stamping mold. Background Art

[0002] A mold is a forming device. Stamping molds are mainly used for the forming of metal materials. Generally, metal sheets are placed in the stamping mold and pressure is applied to the sheet to finally form the desired shape.

[0003] However, the prior art still has some shortcomings. In the prior art, there is a lack of a device for automatically lubricating the guide rod. The guide rod will wear out after long-term work, which will cause the punch to shift, thereby reducing the accuracy.

[0004] Therefore, we propose a high-precision metal stamping die to solve this problem. Utility Model Content
