Description

Technical Field

[0001] This utility model relates to the field of automotive mold processing technology, and in particular to a replacement structure for automotive parts stamping dies. Background Technology

[0002] Automotive parts are a collective term for all the components that make up a car. Automotive parts stamping dies are tools used to manufacture automotive parts. They process metal sheets into the required shapes and sizes through stamping processes. The principle is to use a die mounted on a press to apply pressure to the metal sheet placed in the die cavity, causing it to undergo plastic deformation under the action of the die, thereby obtaining automotive parts stampings that conform to the shape of the die cavity.

[0003] To this end, patent CN221657663U discloses an automotive parts stamping die that facilitates die replacement. The die includes a processing table, with a vertically pushing hydraulic rod positioned below it. A vertically pushing rod is fixedly connected to the telescopic end of the hydraulic rod, and its top end extends through the processing table and into its interior. A vertically pushing plate is fixedly connected to the top end of the pushing rod and slidably connected to the interior of the processing table. This automotive parts stamping die, which facilitates die replacement, allows for easy upward movement of the lower stamping die through the cooperation of the processing table, the vertically pushing hydraulic rod, the vertically pushing rod, the vertically pushing plate, and the lower stamping die. Furthermore, the cooperation of the horizontally pushing hydraulic rod, the horizontally pushing rod, and the horizontally pushing plate facilitates die replacement when the lower stamping die is moved to the appropriate position.

[0004] The existing technical solutions mentioned above have the following drawbacks: although the lower stamping die can be replaced, it is inconvenient to quickly disassemble and replace the upper stamping die, which affects the efficiency of the overall replacement of the stamping die and thus reduces the efficiency of stamping processing of automotive parts. Utility Model Content

[0005] The purpose of this utility model is to provide a replacement structure for stamping dies of automotive parts, so as to solve the defects of existing replacement structures for stamping dies of automotive parts, which make it inconvenient and difficult to quickly disassemble and replace the upper stamping die.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a replacement structure for stamping dies of automotive parts, including a base;

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 The present invention provides a replacement structure for stamping dies for automotive parts, including a base 1.

[0031] Reference Figure 1 and Figure 2 As shown, a guide rod 2 is fixedly connected to the top of the base 1, a top plate 3 is fixedly connected to the top of the guide rod 2, a hydraulic rod 4 is fixedly connected to the top of the top plate 3, the output end of the hydraulic rod 4 is fixedly connected to the top of the movable plate 61, and the top plate 3 is set parallel to the base 1.

[0032] By activating the hydraulic rod 4, the movable plate 61 can slide down along the guide rod 2, which can stabilize the movable plate 61 during the stamping process.

[0033] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a first magnetic block 5 is fixedly connected to the bottom of the top plate 3. A replacement mechanism 6 is installed on the outer wall of the guide rod 2. The replacement mechanism 6 includes a movable plate 61 movably installed on the outer wall of the guide rod 2. A docking groove 62 is opened inside the movable plate 61. A docking block 63 is installed inside the docking groove 62. An upper stamping die 64 is fixedly connected to the bottom of the docking block 63. A support rod 65 is fixedly connected to the top of the movable plate 61. A T-shaped locking block 66 is movably connected to the outer wall of the support rod 65. A first spring 67 is fixedly connected to the top of the T-shaped locking block 66. A second magnetic block 68 is fixedly connected to the top of the T-shaped locking block 66. The movable plate 61 and the guide rod 2 form a sliding structure. The movable plate 61 is engaged with the docking block 63 through the docking groove 62. The T-shaped locking block 66 and the support rod 65 form a sliding structure. The first spring 67 is sleeved on the outer wall of the support rod 65. The T-shaped locking block 66 and the movable plate 61 form a sliding structure. The second magnetic block 68 is magnetically attracted to the first magnetic block 5.

[0034] By activating the hydraulic rod 4, the movable plate 61 slides upward along the guide rod 2. When the movable plate 61 approaches the top plate 3, under the magnetic attraction of the second magnetic block 68 and the first magnetic block 5, the T-shaped locking block 66 can slide upward along the support rod 65, causing the second magnetic block 68 and the first magnetic block 5 to magnetically adhere. At this time, the T-shaped locking block 66 slides along the movable plate 61 and releases the obstruction limit on the docking block 63. Pulling the upper stamping die 64 outward, the docking block 63 can slide out along the docking groove 62, allowing the upper stamping die 64 to be disassembled. Similarly, the required upper stamping die 64 can be replaced, and the docking block 63 can be inserted into the docking groove 62. Activating the hydraulic rod 4 causes the movable plate 61 to slide along the guide rod 2, causing the second magnetic block 68 to separate from the first magnetic block 5. Under the action of the first spring 67, the T-shaped locking block 66 can slide back to its original position along the support rod 65 and obstruct the docking block 63.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a disassembly mechanism 7 is installed inside the base 1. The disassembly mechanism 7 includes a slot 71 opened inside the base 1, a plug 72 installed inside the slot 71, and a lower stamping die 73 fixedly connected to the top of the plug 72. The disassembly mechanism 7 also includes a limiting plate 74 movably installed inside the base 1. A second spring 75 is fixedly connected to the bottom of the limiting plate 74, and a receiving plate 76 is fixedly connected to one side of the limiting plate 74. The base 1 is engaged with the plug 72 through the slot 71. The limiting plate 74 and the base 1 form a sliding structure. The second spring 75 is symmetrically arranged about the central axis of the limiting plate 74.

[0036] By pressing down the receiving plate 76, the limiting plate 74 can slide down along the base 1 and release the blocking limit on the insert 72. Pulling the lower stamping die 73 can make the insert 72 slide out along the slot 71, disassemble the lower stamping die 73, replace the required lower stamping die 73, and slide the insert 72 into the slot 71. Release the receiving plate 76, and under the action of the second spring 75, the limiting plate 74 can be reset and block the insert 72.
