Description

Technical Field

[0001] The utility model belongs to the technical field of metal molds, and in particular relates to a metal seamless forming mold structure. Background Art

[0002] At present, the common structure of metal sheet bending in hardware molds is to set a lower support block on the lower mold, and set an upper pressure block and forming punch on the upper mold. The metal sheet is clamped by the upper pressure block and the lower support block, and the forming punch moves up and down with the upper mold to press the edge of the metal sheet from the side of the lower support block, so that the edge of the metal sheet is bent. After the bending contact, the upper pressure block and the forming punch rise and reset directly, and demold at the same time. However, because the forming punch rubs the outer surface of the metal sheet vertically downward, there are obvious scratches on the outer area of ​​the metal sheet, which affects the appearance of the sheet.

[0003] After searching, a document with publication number (CN217290052U) discloses a metal seamless forming mold structure, including an upper mold and a lower mold. The upper mold can move up and down and is located directly above the lower mold. It also includes an upper pressure block, a forming block, a stop block and a lower support block. The upper pressure block is elastically fixed on the upper mold along the longitudinal direction, and the lower support block is fixed on the lower mold. The upper pressure block and the lower support block are arranged opposite to each other to achieve clamping and fixation of the non-bending part of the metal sheet.

[0004] The above device changes the straight-up and straight-down downward punch bending structure. By designing the forming block to be able to rotate around a horizontal axis, the slider mechanism on the lower die drives it to rotate to achieve bending of the edge of the metal sheet, thereby avoiding friction between the forming block and the bending edge of the metal sheet during bending. When the forming block rises and resets, it automatically opens under the action of the upper ejector and does not contact the bending edge of the metal sheet, thereby avoiding wear marks on the bending edge of the metal sheet caused by friction with the forming block.

[0005] The above device does not have the function of fixing metal sheets of different sizes, so the device can only fix and clamp metal sheets of the same size, which limits the types of metal sheets that can be stamped. When stamping different metal sheets, the stamping base plate needs to be replaced.

[0006] In view of this, the present utility model is proposed. Utility Model Content
