Technical Field

[0001] This utility model belongs to the field of stamping die technology, and specifically relates to an easily disassembled stamping die for automotive parts. Background Technology

[0002] Stamping dies for automotive parts are special process equipment used in cold stamping to process metal or non-metal materials into parts of the required shape and size. They use dies mounted on a press to apply pressure to the material, causing it to separate or plastically deform, thereby obtaining the desired parts. Stamping dies are an indispensable and important tool in the automotive manufacturing industry.

[0003] For example, Chinese patent CN217451784U discloses an easily detachable stamping die for automotive parts, including a base plate. Two protective plates are symmetrically arranged above the base plate, and the base plate is fixedly connected to the two protective plates. A top plate is fixedly connected above the protective plates, and a hydraulic rod is arranged below the top plate. Two automotive part molds are opened above the base plate. Two mold grooves are symmetrically opened at the bottom of the automotive part molds, and the automotive part molds are located in the mold grooves. Movable grooves are opened on both sides of the mold grooves.

[0004] Although the aforementioned patents have solved the problem that existing automotive parts stamping dies are difficult or impossible to disassemble after use, automotive dies are often complex in structure and heavy in weight. Relying on manual force to push the dies for disassembly is extremely time-consuming and laborious, which greatly affects production efficiency. In addition, the dies are usually placed directly below the stamping head. This special placement not only limits the operating space, but also increases the inconvenience and complexity of the disassembly process, making the disassembly of the dies particularly difficult.

[0012] In summary, the present invention has the following main advantages:

[0013] First, in this utility model, by setting a placement plate and installing a first power component on the placement plate, the first power component drives the first lead screw to rotate inside the placement plate, driving the transmission block on its surface to move, so that the transmission block drives the mounting frame to move, thereby causing the mounting frame to push the mold seat to move. This eliminates the need for manual sliding and pushing out, reducing the time and labor required for manual disassembly, reducing employee fatigue and potential work injury risks caused by long-term physical labor, and the mold seat can be installed externally afterward, eliminating the need for installation in the original location, thus reducing the difficulty of operation.

[0014] Secondly, in this utility model, after the mold base is pushed down from the placement plate, the mold base can be quickly separated from the mounting frame by using the second power component and the connecting component. Then, the mold base can be pulled to move, and the pulley at its bottom can slide in the groove of the placement plate, so that the mold base can be easily removed and replaced with a new automotive parts mold base. This makes the disassembly process smoother and more convenient. This not only improves the flexibility of operation, but also reduces the risk of errors and damage caused by inconvenient operation.

A transmission block 6 is threadedly connected to the outer surface of the first lead screw 5. A first power assembly 11 is provided on one side of the placement plate 1 at the first lead screw 5. One side of the transmission block 6 is slidably connected to the placement plate 1. A mounting frame 7 is fixedly connected to one side of the transmission block 6. A die seat 8 is provided on the placement plate 1. A connecting assembly 12 is provided between the die seat 8 and the mounting frame 7. A second power assembly 13 is provided on one side of the connecting assembly 12 on the mounting frame 7.

[0023] refer to Figure 1 The first power assembly 11 includes a first motor 111, which is fixedly connected to one end of the placement plate 1. A first driving gear 112 is fixedly connected to the output end of the first motor 111. A first driven gear 113 is meshed with one side of the first driving gear 112. The first driven gear 113 is fixedly connected to the first lead screw 5. By setting the first power assembly 11, the first motor 111 drives the first driving gear 112 to rotate, and the first driving gear 112 drives the first driven gear 113 to rotate, so that the first driven gear 113 drives the first lead screw 5 to rotate, thereby achieving a smooth transmission and driving the transmission block 6 to move.

[0024] refer to Figure 4-5 The connecting assembly 12 includes a connecting groove 121, which is formed inside the mounting bracket 7. A connecting block 122 is inserted into the connecting groove 121. One end of the connecting block 122 is fixedly connected to one end of the mold base 8. A positioning hole 123 is formed inside the connecting block 122. A positioning rod 124 is inserted into the positioning hole 123. The positioning rod 124 is slidably connected to the mounting bracket 7 through the second power assembly 13. A limit block 1241 is fixedly connected to one side of the positioning rod 124. The limiting block 1241 is slidably connected inside the mounting frame 7. By setting the connecting component 12, the connecting block 122 on one side of the mold base 8 is inserted into the connecting groove 121 of the mounting frame 7. The second power component 13 drives the positioning rod 124 to move, so that the positioning rod 124 is inserted into the positioning hole 123, and the connecting block 122 is connected and fixed to the connecting groove 121. This fixes the mold base 8 to the mounting frame 7, allowing the mold base 8 to move with the mounting frame 7. The limiting block 1241 limits the sliding distance of the positioning rod 124.

[0025] refer to Figure 5The second power assembly 13 includes a second motor 131, which is fixedly connected to the top of the mounting bracket 7. A second drive gear 132 is fixedly connected to the output end of the second motor 131. A second driven gear 133 is meshed with one side of the second drive gear 132. A second lead screw 134 is fixedly connected to one side of the second driven gear 133. The second lead screw 134 is rotatably connected inside the mounting bracket 7. The positioning rod 124 is threadedly connected to the second lead screw 134. By setting the second power assembly 13, the second motor 131 drives the second drive gear 132 to rotate, the second drive gear 132 drives the second driven gear 133 to rotate, and the second driven gear 133 drives the second lead screw 134 to rotate, thereby driving the positioning rod 124 to move and insert it into the positioning hole 123, fixing the connecting block 122 and the connecting groove 121, thus fixing the mold base 8. Conversely, the mold base 8 can be disassembled and removed from the mounting bracket 7.

[0026] refer to Figure 4 The mounting bracket 7 has grooves 14 on both sides near the mold base. A spring 15 is fixedly connected inside the groove 14, and an assist block 16 is fixedly connected to one end of the spring 15. One side of the assist block 16 is attached to one side of the mold base 8. By setting the groove 14, the assist block 16 is connected to the groove 14 through the spring 15. When the mold base 8 is fixed to the mounting bracket 7, the assist block 16 compresses the spring 15 to make it contract within the groove 14. Once the connecting block 122 and the connecting groove 121 are no longer fixed, the spring 15 resets the assist block 16, pushing the mold base 8 to separate from the mounting bracket 7, which provides certain convenience for the operator to remove the mold base 8 for work.

[0027] Operating principle and advantages: The cylinder 3 drives the stamping head 4 to stamp the automotive parts placed in the mold base 8. When the mold base 8 needs to be replaced, the first motor 111 drives the first drive gear 112 to rotate, which in turn drives the first driven gear 113 to rotate. This causes the first driven gear 113 to drive the first lead screw 5 to rotate, which in turn drives the transmission block 6 to move. The transmission block 6 then drives the mounting bracket 7 to move, thus providing power for the mold base 8 to move. The pulley 9 slides in the slide groove 10, causing the mold base 8 to move outward on the placement plate 1, reducing the burden of manual mold disassembly. Because the mold base 8 is offset... The stamping head 4 facilitates the removal and subsequent replacement of the mold base 8. When the mold base 8 needs to be removed, the second motor 131 drives the second drive gear 132 to rotate, which in turn drives the second driven gear 133 to rotate. The second driven gear 133 then drives the second lead screw 134 to rotate, which in turn drives the positioning rod 124 to move, causing the positioning rod 124 to leave the positioning hole 123. At this time, the connecting block 122 and the connecting groove 121 are no longer fixed. Pulling the mold base 8 causes the pulley 9 to slide in the sliding groove 10, which allows the mold base 8 to be removed without lifting it, saving time and effort and making the disassembly process smoother and more convenient.
