Novel composite die for producing anode plate and production method thereof

The invention discloses a novel composite die for producing an anode plate and a production method of the novel composite die, which solve the problems that the existing cast iron die is easy to crack, short in service life and the like, and is characterized in that heat dissipation reinforcing ribs (7) are arranged at the middle upper part of the periphery of a die body (1), and a heat dissipation groove (10) is additionally formed in the local part of a die bottom (6); thick-wall seamless steel pipes (8) are uniformly arranged at the middle stress concentration part; the die body (1) is provided with a thick-wall seamless steel pipe (8), a lower die bottom (6) is made of a medium silicon cast iron material, an upper cavity bottom, a die cavity frame and other parts are made of a heat-resistant cast iron material, a special process material formula is selected, molten iron eutectic is achieved when two kinds of molten iron are mixed in a crossed mode, and a pouring process is adopted for two-time connection
