[0016] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0017] like Figures 1 to 3 As shown, in this embodiment, a core-pulling deformation mold includes an upper mold base 1, a lower mold base 2, two non-deformable rods 3 and a plurality of deformable blocks 4. A forming position is provided between the upper mold base 1 and the lower mold base 2. The two non-deformable rods 3 are respectively located on both sides of the forming position. An arc groove is provided at the inner end of the non-deformable rod 3. An arc strip 5 is provided on the side of the deformable block 4 close to the non-deformable rod 3. The arc strip 5 is located in the arc groove, and the deformable block 4 swings around the middle of the arc strip 5.
[0018] At the position where the square tube needs to be bent, the non-deformable rod 3 controls the entry and exit of the deformable block 4 laterally. When the position of the deformable block 4 changes, the arc strip 5 rotates a certain angle in the arc groove to change the orientation position of each of the deformable blocks, thereby meeting the bending requirements inside the square tube product and the tolerance can also be met.

The driving end of the driving cylinder is hinged with a driving block 7, and the driving block 7 is connected to the outer end of the non-deformable rod 3. During the movement of the non-deformable rod 3, the driving cylinder controls the insertion and extension of the driving block 7, thereby driving the non-deformable rod 3 forward and backward.
[0020] An upper die punch 8 is arranged in the middle of the upper die base 1 . The upper die punch 8 moves on the upper die base 1 along the vertical direction. The upper die punch 8 is used to perform punching processing on square tube products.
[0021] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used.
