[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] like Figures 1 to 3 As shown, an automotive sheet metal bending die includes a top plate 1, a bottom plate 2, a support column 3, a lifting cylinder 4, a telescopic rod 5, a lifting pressure plate 6, an upper bending die 7, a first socket 8, a rotating baffle assembly 9, a lower bending die 10, a second socket 11, a second slot 12, an insertion support block assembly 13, a positioning rod 14, and a buffer spring 15.

[0023] Several supporting columns 3 are provided between the top plate 1 and the bottom plate 2. A lifting cylinder 4 is fixed on the top plate 1. The bottom of the telescopic rod 5 of the lifting cylinder 4 is connected to a lifting pressure plate 6. An upper bending mold 7 is installed under the lifting pressure plate 6. The top left and right sides of the upper bending mold 7 are provided with first sockets 8. The bottom left and right sides of the lifting pressure plate 6 are provided with first slots. The first sockets 8 are inserted into the first slots. Rotating baffle assemblies 9 are provided on the left and right side walls of the lifting pressure plate 6 corresponding to the first sockets 8. A lower bending mold 10 is installed on the bottom plate 2. The bottom left and right sides of the lower bending mold 10 are provided with second sockets 11. The top left and right sides of the bottom plate 2 are provided with second slots 12. The second sockets 11 are inserted into the second slots 12. Insertion support block assemblies 13 are provided on the bottom plate 2 on the left and right sides of the lower bending mold 10.

[0024] The first slot has a T-shaped structure.

[0025] The second slot 12 has an inverted T-shaped structure.

[0026] The upper bending die 7 and lower bending die 10 of this utility model can be installed more conveniently by plugging them together, and can be limited by corresponding limiting devices to prevent displacement. This allows for easier replacement of the required bending die type and higher efficiency.

[0027] The rotating baffle assembly 9 includes a baffle 901, which is mounted on the left and right side walls of the lifting pressure plate 6 via a rotating shaft 902. The rotating shaft 902 is located directly above the first slot, and a rotating handle 903 is provided on the outer end face of the baffle 901.
