[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figs. 1-3 A stamping die for an automotive frame component includes a frame body 1. A lower die cavity 2 is formed on the bottom inner wall of the frame body 1, and an ejection assembly for ejecting the formed part is provided within the lower die cavity 2. An upper die 7 is provided on the top of the frame body 1 via a lifting assembly. Slide grooves 3 are formed on both sides of the bottom inner wall of the frame body 1, and slide plates 4 are slidably connected within the slide grooves 3. Slots 12 are formed on opposite sides of the two slide plates 4, and the height of the slots 12 is the same as the thickness of the sheet metal. Extrusion assemblies are provided on both sides of the upper die 7 to move the two slide plates 4 towards the center. Extrusion assemblies are provided on the top of the two slide plates 4 to move the slide plates 4 towards the center. The pull assembly for resetting the plate frame 4 is used to place the plate between the two slots 12, thereby limiting the left and right positions of the plate and improving the accuracy of plate stamping. The lifting assembly drives the upper mold 7 to move downward. With the cooperation of the lower mold cavity 2 and the upper mold 7, the plate is stamped and formed. At the same time, the extrusion assembly will drive the two slide frames 4 to move synchronously to the middle point, so that the plate is always in the slot 12. After extrusion forming, the plate will be pushed out of the lower mold cavity 2 by the push assembly, and the slide frame 4 will be reset by the pull assembly, which facilitates the next processing.

[0023] In this utility model, the ejector assembly includes two sliding holes 15, both of which are opened on the bottom inner wall of the lower mold cavity 2. A top cylinder 13 is slidably connected in each of the two sliding holes 15. The height of the top cylinder 13 is the same as the depth of the sliding hole 15. A spring 14 is fixed to the top inner wall of the top cylinder 13 by bolts, and the other end of the spring 14 is fixed to the sliding hole 15. During stamping, the sheet metal will squeeze the top cylinder 13 and slide into the sliding hole 15. When the top cylinder 13 is completely inserted into the sliding hole 15, the stamping is completed. When the upper mold 7 is reset upward, the upper mold 7 is disengaged from the sheet metal, the sheet metal loses downward pressure, and the compressed and deformed spring 14 will push the top cylinder 13 to move upward, thereby lifting the sheet metal and creating a gap between the sheet metal and the frame 1, which facilitates the removal of the formed sheet metal.

[0024] The lifting assembly includes a hydraulic cylinder 8, which is bolted to the top outer wall of the frame 1. The piston rod of the hydraulic cylinder 8 passes through the frame 1 and is fixed to the upper mold 7. The top of the upper mold 7 is bolted to a guide frame 9, which passes through the frame 1 and is slidably connected to the frame 1. When the hydraulic cylinder 8 is activated, it drives the upper mold 7 to move downward, thereby stamping the sheet metal. The guide frame 9 limits the movement of the upper mold 7, preventing the upper mold 7 from rotating during movement and improving the stability of the upper mold 7's movement.

[0025] The extrusion assembly includes two clamps 10, which are welded to both sides of the upper mold 7. The tops of the two slide frames 4 are fixed with connecting frames 6 by bolts. One side of the connecting frame 6 does not extend beyond the side of the slide frame 4 where the slot 12 is opened. The outer walls of both sides of the connecting frame 6 are provided with guide grooves 16, and one end of the clamp 10 can slide in the guide groove 16. When the upper mold 7 moves downward, it will drive the two clamps 10 to move downward, so that the clamps 10 fall into the slot 12 and squeeze the slot 12, thereby pushing the slide frame 4 to move towards the middle, so that the slide frame 4 moves synchronously with the stamping of the sheet metal, avoiding displacement of the sheet metal during the stamping process, and further improving the positioning effect of the device.

[0026] The pulling component includes a limiting frame 5, which is fixed to the bottom inner wall of the frame 1 by bolts. A tension spring 11 is fixed to one side of the limiting frame 5 by bolts, and the other end of the tension spring 11 is fixed to the slide frame 4. After stamping, the deformed tension spring 11 will pull the slide frame 4 to assist in resetting, so that the slide frame 4 can be in its original position. At the same time, it can limit the position of the slide frame 4, so that the card holder 10 can fall into the card slot 12 next time, improving the smoothness of the device operation.

[0027] Working principle: During use, the sheet metal is placed between the two slots 12, thereby limiting the left and right positions of the sheet metal. The hydraulic cylinder 8 is activated, causing the upper mold 7 to move downwards. With the cooperation of the lower mold cavity 2 and the upper mold 7, the sheet metal is stamped. During the downward movement of the upper mold 7, the two clamping brackets 10 move downwards, causing them to fall into the slots 12 and press against them. This pushes the sliding plate frame 4 towards the center, ensuring that the sliding plate frame 4 moves synchronously with the stamping of the sheet metal, preventing displacement of the sheet metal during stamping. During stamping, the sheet metal will be squeezed... The top cylinder 13 slides into the sliding hole 15. When the top cylinder 13 is fully inserted into the sliding hole 15, the stamping is completed. After the stamping is completed, the deformed tension spring 11 will pull the slide frame 4 to assist in the reset, so that the slide frame 4 can be in its original position. At the same time, it can limit the position of the slide frame 4, so that the next clamp 10 can fall into the clamp slot 12. When the upper mold 7 resets upward, the upper mold 7 disengages from the plate, the plate loses the downward pressure, and the compressed and deformed spring 14 will push the top cylinder 13 to move upward, thereby lifting the plate and creating a gap between the plate and the frame 1, which makes it easier to remove the formed plate.

[0028] Finally, it should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
