The utility model can separate the upper die and the lower die after the stamping is completed, which is conducive to the rapid removal and placement of the stamped parts after the stamping is completed, and is also conducive to the cleaning effect of the die after the stamping process, greatly improving the convenience of use.

[0004] The high-precision stamping dies in the above-mentioned comparative documents have the following shortcomings: it is difficult to stamp parts continuously, and after stamping, the stamped parts need to be manually removed from the stamping dies, which is cumbersome and reduces the production speed of stamping parts. In addition, there are risks in manually removing stamped parts.

[0005] For this purpose we designed a high-precision stamping die. Utility Model Content

[0006] The technical problem solved by the utility model is to provide a high-precision stamping die with high practicality, simple operation and relatively simple structure, which solves the problem of difficulty in continuously stamping parts raised in the above-mentioned background technology and the need to manually remove the stamped parts from the stamping die after the stamping is completed.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a high-precision stamping die, comprising a base, one side of the base is fixedly connected to an L-shaped rod, one side of the L-shaped rod is fixedly connected to a first cylinder, the surface of the first cylinder is rotatably connected to a guide rod, one end of the guide rod is rotatably connected to a second cylinder, one end of the second cylinder is fixedly connected to a material guide plate, one side of the surface of the guide rod is rotatably connected to a first round rod, one end of the first round rod is fixedly connected to a movable rod, one side of the movable rod is fixedly connected to a second round rod, and the surface of the second round rod is rotatably connected to a connecting block.

[0008] Optionally, a lower mold is fixedly connected to the top center of the base, and a groove is opened at the top center of the lower mold, and the groove is convenient for stamping parts.

[0009] Optionally, support columns are fixedly connected to the top of the base, a movable plate is slidably connected to one side of the surface of the support column, a connecting block is fixedly connected to one side of the movable plate, an upper mold is fixedly connected to the bottom center of the movable plate, and the upper mold cooperates with the lower mold to stamp the parts.

[0010] Optionally, a raised block corresponding to the top groove of the lower mold is provided at the bottom center of the upper mold, and springs are fixedly connected around the bottom of the upper mold. A buffer rod is sleeved inside the spring, and a pressure plate is fixedly connected to one end of the spring. The pressure plate can first support the part to make it difficult to move during stamping.

[0011] Optionally, a fixed plate is fixedly connected to the other side of the surface of the support column, and a ejector pin is fixedly connected to the bottom of the fixed plate. The ejector pin can eject the stamping part stuck on the upper mold, and one end of the ejector pin passes through the movable plate and the upper mold.

[0012] Optionally, a rectangular plate is fixedly connected to the top of the support column, a hydraulic rod is fixedly connected to the bottom of the rectangular plate, the hydraulic rod can move up and down on the movable plate, and one end of the hydraulic rod passes through the fixed plate and is fixedly connected to the movable plate.

[0013] The utility model provides a high-precision stamping die, which has the following beneficial effects:

[0014] The high-precision stamping die places the part on the lower die through the arrangement of the L-shaped rod, the first cylinder, the guide rod, the second cylinder, the guide plate, the first round rod, the movable rod, the second round rod, the connecting block, the fixed plate and the ejector pin, and opens the hydraulic rod to drive the movable plate to descend. While descending, the connecting block on one side of the movable plate drives the movable rod to move, so that the movable rod drives one end of the guide rod to move toward the outside of the device, and drives the guide plate to leave between the upper die and the lower die, so as to stamp the part. After stamping, the hydraulic rod is opened to drive the movable plate to rise. While rising, the guide rod is driven to move toward the inside of the device through the movable rod, and then the guide plate is driven to move to the bottom of the upper die. While rising, the ejector pin ejects the stamping part stuck on the surface of the upper die, so that it falls to the middle of the guide plate for easy collection, thereby playing a role in continuously stamping the part, improving the stamping speed of the part, and reducing the danger of manually taking out the stamping part.
