Description

Technical Field

[0001] This utility model relates to the field of automotive stamping technology, specifically to an automotive stamping die. Background Technology

[0002] Many automotive parts are produced using stamping dies. Stamping dies are special process equipment used in cold stamping to process metal or non-metal materials into parts or semi-finished products. Stamping dies play an indispensable role in the stamping process. Stamping dies generally include an upper pressure plate and a lower pressure plate. During the stamping production process, the upper pressure plate is driven by a cylinder to impact and squeeze the lower pressure plate, thereby processing the parts.

[0003] After the existing parts are stamped, the operator needs to remove them from the lower pressure plate by hand. However, there is a great safety hazard for the operator to place their hands on the upper and lower pressure plates. At the same time, the operator's attention needs to be focused on the upper and lower pressure plates. Working for a long time will consume a lot of time and energy.

[0004] Therefore, there is a need to provide an automotive stamping die. Utility Model Content

[0005] The purpose of this utility model is to provide an automotive stamping die to solve the problem mentioned in the background art that there is a great safety hazard when the operator places his hands on the upper and lower pressure plates, and at the same time, the operator's attention needs to be focused on the upper and lower pressure plates, which consumes a lot of time and energy during long-term work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automotive stamping die, comprising a worktable, with support legs fixedly installed at the four corners of the bottom of the worktable, moving die assemblies fixedly installed on both sides of the top of the worktable, a demolding assembly for demolding installed at the bottom of the moving die assemblies, a fixed die assembly fixedly installed in the middle of the top surface of the worktable, a pushing assembly installed on one side of the worktable, two first through holes opened in the middle of the worktable, and second through holes opened on both sides of the connection between the worktable and the fixed die. Preferably, a control panel is fixedly installed at one end of the top of the worktable, and a stamping switch and a pushing switch are sequentially installed on the surface of the control panel, concentrating various control functions of the stamping process on one control panel, greatly improving the convenience and efficiency of operation, and reducing operation time and labor intensity.

[0007] Preferably, the moving mold assembly includes two hydraulic rods, which are respectively installed on both sides of the top of the worktable. A top plate is fixedly installed at one end between the two hydraulic rods, and a mounting shell is fixedly installed at the center of the bottom of the top plate. The moving mold is fixedly installed inside the mounting shell by screws. The hydraulic rods are electrically connected to an external power supply through a stamping switch. During operation, the hydraulic rods can provide stable pressure output and maintain a nearly constant pressure throughout the entire stamping stroke, making the quality of the stamped parts more uniform and consistent, reducing problems such as part deformation and dimensional deviation caused by pressure fluctuations. The simple fixing method makes the moving mold easy to disassemble and install.

[0008] Preferably, the fixed mold assembly includes a fixed mold, with mounting plates fixedly installed at both ends of both sides of the fixed mold. All four mounting plates are fixed to the top of the worktable by screws. The bottom of the fixed mold has a circular hole corresponding to the first through hole. A sliding plate is slidably installed inside the fixed mold. A demolding module is fixedly installed at the bottom of the sliding plate. The sliding rod of the demolding module is slidably installed inside between the first through hole and the circular hole, which facilitates demolding and allows all parts of the part to be evenly and smoothly removed from the fixed mold. This prevents damage or loss of the internal structure of the part due to poor demolding in some areas, ensuring the integrity of the part structure and the reliability of its function.

[0009] Preferably, the demolding assembly includes two connecting pillars, the tops of which are fixedly installed at both ends of the bottom of the top plate, and the middle parts of which are slidably installed inside the two second through holes. A lifting plate is fixedly installed at the bottom between the two connecting pillars. The lifting plate is movably connected to the bottom of the demolding module. Compared with some manual or traditional demolding methods, this greatly shortens the demolding time, thereby improving the cycle time of the entire stamping production and increasing the output per unit time.

[0010] Preferably, the pushing component includes a mounting frame, which is fixedly installed on one side of the worktable. An electric push cylinder is fixedly installed on the top of the mounting frame. The electric push cylinder is electrically connected to an external power supply through a push switch. It can accurately push the demolded workpiece to a designated position according to a preset program and rhythm, providing strong support for realizing a fully automated production process, reducing manual intervention, and improving the degree of automation and production efficiency.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The fixed mold assembly facilitates demolding, allowing all parts of the part to be evenly and smoothly removed from the fixed mold. This prevents damage or loss of the internal structure of the part due to poor local demolding, ensuring the integrity of the part structure and the reliability of its function.

[0013] Compared to some manual or traditional demolding methods, the demolding assembly greatly shortens the demolding time, thereby improving the cycle time of the entire stamping production and increasing the output per unit time.

[0014] By accurately pushing the demolded workpiece to the designated position using the pusher component, it provides strong support for achieving a fully automated production process, reduces manual intervention, and improves the level of automation and production efficiency.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5 This utility model provides an automotive stamping die, including a worktable 1. Support legs 2 are fixedly installed at the four corners of the bottom of the worktable 1. Moving mold assemblies are fixedly installed on both sides of the top of the worktable 1. A demolding assembly for demolding is installed at the bottom of the moving mold assembly. A fixed mold assembly is fixedly installed in the middle of the top surface of the worktable 1. A pushing assembly is installed on one side of the worktable 1. Two first through holes 15 are opened in the middle of the worktable 1. Second through holes 16 are opened on both sides of the connection between the worktable 1 and the fixed mold 10.

[0023] Furthermore, a control panel 3 is fixedly installed at one end of the top of the workbench 1. A stamping switch and a push switch are sequentially installed on the surface of the control panel 3. The entire stamping process is centrally controlled through the control panel 3. The hydraulic rod 4 is controlled to work through the stamping switch, and the electric push cylinder 8 is controlled to work through the push switch.

[0024] Furthermore, the moving mold assembly includes two hydraulic rods 4, which are respectively installed on both sides of the top of the worktable 1. A top plate 5 is fixedly installed at one end between the two hydraulic rods 4. A mounting shell 6 is fixedly installed at the center of the bottom of the top plate 5. The moving stamping mold 7 is fixedly installed inside the mounting shell 6 by screws. The hydraulic rods 4 are electrically connected to an external power supply through a stamping switch. First, the workpiece material to be stamped is accurately placed into the inside of the fixed mold 10. The hydraulic rods 4 are started to work by controlling the stamping switch, so that the hydraulic rods 4 descend. When the hydraulic rods 4 descend, they drive the top plate 5 to descend. The top plate 5 drives the moving stamping mold 7 fixed at the bottom to descend towards the fixed mold 10 to process the workpiece to be stamped.

[0025] Furthermore, the fixed mold assembly includes a fixed mold 10. Mounting plates 11 are fixedly installed at both ends of both sides of the fixed mold 10. All four mounting plates 11 are fixed to the top of the worktable 1 by screws. The bottom of the fixed mold 10 has a circular hole corresponding to the first through hole 15. A sliding plate 13 is slidably installed inside the fixed mold 10. A demolding module 14 is fixedly installed at the bottom of the sliding plate 13. The sliding rod of the demolding module 14 is slidably installed inside the space between the first through hole 15 and the circular hole. When the lifting plate 12 rises, it squeezes the demolding module 14 at the top, causing the sliding rod of the demolding module 14 to slide and rise inside the space between the two first through holes 15 and the circular hole. When the demolding module 14 slides and rises, it drives the sliding plate 13 fixedly installed at the top to slide and rise inside the fixed mold 10, pushing the workpiece stamped inside the fixed mold 10 upward for demolding.

[0026] Furthermore, the demolding assembly includes two connecting pillars 9. The tops of the two connecting pillars 9 are fixedly installed at both ends of the bottom of the top plate 5, and the middle parts of the two connecting pillars 9 are slidably installed inside the two second through holes 16. A lifting plate 12 is fixedly installed at the bottom between the two connecting pillars 9. The lifting plate 12 is movably connected to the bottom of the demolding module 14. When the top plate 5 descends, it drives the two connecting pillars 9 to move synchronously. After the stamping is completed, the hydraulic rod 4 is controlled to rise by the stamping switch. When the top plate 5 and the stamping moving die 7 rise, the two connecting pillars 9 slide and rise together inside the two second through holes 16. The two connecting pillars 9 drive the lifting plate 12 between the bottoms to rise.

[0027] Furthermore, the pushing component includes a mounting frame 17, which is fixedly installed on one side of the workbench 1. An electric push cylinder 8 is fixedly installed on the top of the mounting frame 17. The electric push cylinder 8 is electrically connected to an external power supply through a push switch. When the sliding plate 13 pushes the processed workpiece to demold, the push switch controls the electric push cylinder 8 to work, pushing the demolded workpiece to a designated position for collection or to enter the next process. This reduces manual intervention and improves the automation level and production efficiency of the production.

[0028] In this embodiment, the workpiece material to be stamped is first accurately placed into the fixed mold 10. The hydraulic rod 4 is activated by the stamping switch, causing it to descend. As the hydraulic rod 4 descends, it drives the top plate 5 to descend as well. The top plate 5 then drives the fixed stamping die 7 to descend towards the fixed mold 10, processing the workpiece. The descent of the top plate 5 causes the two connecting pillars 9 to move synchronously. After stamping is complete, the hydraulic rod 4 is raised by the stamping switch. As the top plate 5 and the stamping die 7 rise, the two connecting pillars 9 slide upward together within the two second through holes 16. The two connecting pillars 9 then drive the bottom... The lifting plate 12 rises, pressing the top ejector module 14, causing the sliding rod of the ejector module 14 to slide and rise inside the two first through holes 15 and the round hole. As the ejector module 14 slides and rises, it drives the top fixed sliding plate 13 to slide and rise inside the fixed mold 10, pushing the workpiece stamped inside the fixed mold 10 upward for demolding. After the sliding plate 13 pushes the processed workpiece to demold, the electric push cylinder 8 is controlled by the push switch to work, pushing the demolded workpiece to the designated position for collection or to enter the next process, reducing manual intervention and improving the automation level and production efficiency of production.
