Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a pressing and beveling side folding forming mold structure. Background Art

[0002] The beveling of parts is generally achieved by stamping with a beveling die. When designing a beveling die, if the tail of the beveled surface of the part is bent, the general beveling die cannot bend the part and can only be bevel the part. In this way, only a single-process die can be added to bend the part, which requires two sets of dies, which increases the mold cost and has low production efficiency. In addition, it is necessary to add a punch press and a worker, which results in high equipment and labor costs and increases electricity costs.

[0003] Therefore, further improvements are necessary. Utility Model Content
