[0002] Sheet metal forming refers to a processing method that obtains the desired shape and size by applying external force to the sheet metal to cause plastic deformation or separation. A common method is stamping: using a press and a mold to apply external force to the sheet metal to cause it to undergo plastic deformation or separation to obtain a workpiece of a specific shape and size.

[0003] When the mold is stamping sheet metal, some products have small negative angles. During the processing, it needs to be divided into flanging and side shaping, which are completed in two steps. There are many processing steps, which affects the processing efficiency. Different molds are required to complete the corresponding steps, which increases the customization cost of the mold.

[0004] In order to reduce the number of processes and reduce mold costs, a structure is required in which the flanging and side shaping of the plate are completed in the same sequence. Utility Model Content

[0022] In a specific embodiment, the upper mold 5 moves downward, and the upper mold side insert 501 contacts the lower mold forming insert 7 and starts to flanging. Before flanging to the bottom, the upper mold side insert 501 contacts the lower mold forming insert 7, and the lower mold forming insert 7 starts to move downward. Finally, the lower mold forming insert 7 and the upper mold side insert 501 are in place at the same time to achieve the effect of flanging side shaping. At the same time, the lower mold anti-side block 8 can constrain the outer side of the upper mold side insert 501 to eliminate the lateral force generated when the product is flanging.

[0023] The technical effect achieved by the above-mentioned embodiment is: the structure of flanging and side shaping can be completed in the same sequence, which occupies a small space and reduces the number of mold processes, which can effectively save mold costs and production costs, reduce waste of resources, make the mold lightweight, and promote the development of the mold industry.
