Technical Field

[0001] This utility model relates to the field of sheet metal stamping die technology, and in particular to a sheet metal stamping die. Background Technology

[0002] Sheet metal stamping dies are special tools designed specifically for processing sheet metal parts (metal sheets with a thickness of 0.1-6mm, such as steel plates, aluminum plates, copper plates, etc.). By working with stamping equipment (such as punch presses and presses) to apply pressure, the metal sheet undergoes plastic deformation or separation, ultimately obtaining parts with specific shapes, sizes, and precision. To this end, patent CN218283447U discloses a sheet metal stamping die, including a die body. The lower part of the die body is provided with a filling seat, a pneumatic top seat, and an operating body. The filling seat is fixedly installed on the lower part of the die body, and the pneumatic top seat is engaged with the lower part of the die body and penetrates through the die body. The lower part of the operating body is movably sealed inside the pneumatic top seat. The operating body is fixedly connected to the die body. The filling seat includes a seat body and a filling block, which are fixedly connected as a single unit. The filling seat also includes a mounting ring and bolts. The mounting rings are symmetrically fixedly connected to the side ends of the seat body, and the bolts movably penetrate the mounting rings. After stamping, the operating body is pushed by hand, causing it to compress the gas inside the pneumatic top seat, causing the rear part of the pneumatic top seat to extend upwards. The rear part of the pneumatic top seat is used to lift the product upwards, making it easy to grasp and pull out the product. The existing technical solutions described above have the following drawbacks: During use, it is inconvenient to stably align the upper and lower dies. This causes the upper die to easily shift during stamping, thus affecting the quality of sheet metal stamping. Utility Model Content

[0003] The purpose of this utility model is to provide a sheet metal stamping die to solve the defect of existing sheet metal stamping dies that make it inconvenient to stably connect the upper and lower dies.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sheet metal stamping die, including a lower die; The lower mold has a forming groove inside, and a guide post is fixedly connected to the top of the lower mold.

[0014] The sheet metal stamping die provided by this utility model has the following advantages: By setting up a lower mold, forming groove, guide column and stamping mechanism, the hydraulic rod can be activated to make the movable plate slide along the top frame, which drives the supporting rod to slide along the movable groove opened inside the movable plate. This causes the upper mold, which is fixedly connected to the bottom end of the supporting rod, to move down, so that the upper mold can stamp the sheet metal in the forming groove. This facilitates the stable docking of the upper mold and the lower mold, thereby improving the quality of stamping the sheet metal. Furthermore, the stability of the moving plate can be improved by the sliding cooperation between the guide plate and the guide groove. Furthermore, the stability of the upper die's downward stamping can be further improved by the guiding action of the guide pillars; By setting up a forming groove, an upper mold, and a demolding mechanism, the upper mold can move upward, which can cause the sleeve plate to pull the support rod upward, and the ejector rod fixedly connected to the top of the base plate to move upward. This causes the ejector rod to eject the sheet metal parts formed in the forming groove, which facilitates the demolding and removal of the formed sheet metal parts. Furthermore, under the action of the return spring, the ejector rod can be moved down and reset, thereby improving the continuity of stamping processing of sheet metal. Attached Figure Description
