[0002] Bending dies are a type of process equipment used for sheet metal processing. They are mainly used to form specific shapes and sizes by changing the physical state of the material. In sheet metal processing, bending dies are particularly suitable for bending stainless steel and aluminum plates, which require no scratches during processing. Bending dies are usually composed of a variety of parts, which vary depending on the specific purpose and design of the mold. Under the action of the bending machine, the mold is driven up and down by the slider to achieve the forming of the sheet. Since plates of different materials, thicknesses, lengths and widths require different shapes and angles, there are bending machines of different tonnages and sizes used with corresponding dies.

[0003] At present, the existing bending molds for grooved parts with outward angles still have some defects when used. They are often not convenient for demolding. After bending and forming, they need to wait for cooling and manually demold after cooling, and the demolding efficiency is low. For this reason, we propose a bending mold for grooved parts with outward angles. Utility Model Content
