Biological disc cutting die

The invention relates to a biological disc cutting die. The biological disc cutting die comprises an upper die body (1) and a lower die body (2). The upper die body (1) comprises a fan-shaped pressing plate (1.1). A fan-shaped frame (1.2) is arranged on the edge of the fan-shaped pressing plate (1.1). A plurality of pressing circular platforms (1.3) are evenly arranged on the fan-shaped pressing plate (1.1). The lower die body (2) comprises a fan-shaped bottom plate (2.1). A second fan-shaped frame (2.2) is arranged on the edge of the fan-shaped bottom plate (2.1). A fan-shaped cutting edge (2.3) is arranged on the second fan-shaped frame (2.2). A plurality of positioning circular platforms (2.4) are evenly arranged on the fan-shaped bottom plate (2.1). Annular cutting edges (2.5) are arranged on the positioning circular platforms (2.4). According to the biological disc cutting die, the cutting efficiency of the edge of a fan-shaped disc and the trepanning position can be greatly improved, and the final fan-shaped disc trepanning precision is guaranteed.
