Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a stamping forming mold for stainless steel corner grooves, comprising: a base 1, a lower mold structure 2 and a stamping structure 3 fixedly connected to the outer wall of the top of the base 1, the outer wall of the lower mold structure 2 being fixedly connected to the outer wall of the stamping structure 3; the lower mold structure 2 includes a lower mold base 21, the outer wall of the top of the lower mold base 21 being symmetrically provided with positioning grooves 22, the inner wall of the lower mold base 21 being symmetrically rotatably connected with threaded rods 23, the outer wall of the threaded rods 23 being threadedly connected with positioning plates 24, the outer wall of the top of the lower mold base 21 being provided with buffer grooves 25, the inner wall of the buffer grooves 25 being slidably connected with a lower module 26, and the outer wall of the bottom of the lower module 26 being fixedly connected with a buffer pad 27.

[0026] The outer wall of the bottom of the buffer pad 27 is fixedly connected to the inner wall of the bottom of the buffer groove 25. The outer wall of the bottom of the positioning plate 24 is slidably connected to the inner wall of the positioning groove 22. The outer wall of the bottom of the lower mold base 21 is fixedly connected to the outer wall of the top of the base 1. When the threaded rod 23 is rotated, since the threaded rod 23 is threadedly connected to the positioning plate 24 and the outer wall of the bottom of the positioning plate 24 is slidably connected to the inner wall of the positioning groove 22, the rotation of the threaded rod 23 will drive the positioning plate 24 to move along the positioning groove 22.

[0027] The inner wall of the lower module 26 is provided with a demolding groove 261. An extrusion plate 262 is slidably connected to the inner wall of the demolding groove 261. A demolding module 263 is fixedly connected to the outer wall of the top of the extrusion plate 262. A pressure spring 264 is fixedly connected to the outer wall of the bottom of the extrusion plate 262.

[0028] The demolding groove 261 is arranged horizontally along the inner wall of the lower module 26. The outer wall of the pressure spring 264 away from the extrusion plate 262 is fixedly connected to the inner wall of the bottom of the demolding groove 261. The outer wall of the demolding module 263 is slidably connected to the inner wall of the lower module 26. When the demolding module 263 is squeezed, it will push the extrusion plate 262 to move downward along the demolding groove 261, and at the same time, the pressure spring 264 is squeezed and stored.

[0029] The stamping structure 3 includes a support frame 31, a hydraulic cylinder 32 is fixedly connected to the outer wall of the top of the support frame 31, an upper module 33 is fixedly connected to the outer wall of the bottom of the hydraulic cylinder 32, and a sliding groove 34 is provided on the outer wall of the side of the support frame 31.

[0030] The outer wall of the side of the upper module 33 is slidably connected to the inner wall of the slide groove 34. The outer wall of the bottom of the upper module 33 is in contact with the inner wall of the top of the lower module 26. The outer wall of the side of the support frame 31 is fixedly connected to the outer wall of the side of the lower mold base 21. The outer wall of the bottom of the support frame 31 is fixedly connected to the outer wall of the top of the base 1. The hydraulic cylinder 32 is activated, and the piston rod of the hydraulic cylinder 32 extends, driving the upper module 33, which is fixedly connected to it, to move up and down along the slide groove 34 opened on the outer wall of the side of the support frame 31.

[0031] In use, the base 1 serves as the support for the entire device. The stainless steel plate is placed on the lower mold structure 2 and fixed by the positioning plate 24. Then, the upper module 33 is driven by the hydraulic cylinder 32 on the stamping structure 3 to stamp the stainless steel plate on the lower module 26.

[0032] First, the stainless steel slab to be stamped is placed on the lower die base 21. By rotating the threaded rod 23, since the threaded rod 23 is threadedly connected to the positioning plate 24 and the bottom outer wall of the positioning plate 24 is slidably connected to the inner wall of the positioning groove 22, the rotation of the threaded rod 23 will drive the positioning plate 24 to move along the positioning groove 22. According to the size of the slab, the position of the two positioning plates 24 is adjusted to accurately position the slab in the horizontal direction, ensuring that the slab is accurately positioned during the stamping process.

[0033] Next, the hydraulic cylinder 32 in the stamping structure 3 is activated. The piston rod of the hydraulic cylinder 32 extends and drives the upper module 33, which is fixedly connected to it, to move downward along the slide groove 34 opened on the outer side wall of the support frame 31. The upper module 33 moves downward and gradually approaches and contacts the inner top wall of the lower module 26, applying pressure to the blank between the upper module 33 and the lower module 26 to stamp it, so that the blank is gradually formed into the shape of a stainless steel corner groove. A buffer pad 27 is fixedly connected to the bottom outer wall of the lower module 26, and the bottom outer wall of the buffer pad 27 is fixedly connected to the bottom inner wall of the buffer groove 25. During the stamping process, when the blank is deformed by the pressure of the upper module 33, the lower module 26 will be subjected to a certain reaction force. At this time, the buffer pad 27 can play a buffering role, absorbing part of the impact force, reducing the instantaneous impact on the lower die base 21, and protecting the lower die base 21 and the entire mold structure.

[0034] As the blank is gradually formed, the outer wall of the bottom of the blank will contact the outer wall of the top of the demolding module 263, causing the demolding module 263 to push the extrusion plate 262 downward along the demolding groove 261. At the same time, the pressure spring 264 is compressed and stored. When the stamping is completed, the piston rod of the hydraulic cylinder 32 retracts and drives the upper module 33 to return to its original position. At this time, the pressure spring 264 located in the demolding groove 261 on the inner wall of the lower module 26 plays a role. After the stamping is completed, the pressure spring 264 releases its elastic potential energy, pushes the extrusion plate 262 upward, and then drives the demolding module 263 to move upward, pushing the formed stainless steel corner groove out of the forming groove of the lower module 26, completing the demolding process, and making it convenient for the operator to take out the formed part.
