step two: during feeding, an output rod of the second driving oil cylinder (35) extends to push the feeding mechanism (5) to rotate by taking the central rotating shaft (33) as a circle center, the feeding mechanism (5) inclines, a metal bar material leaks from the inner structure of the material storage mechanism (1), the metal bar material enters the second feeding hopper (12) through the feeding metal hose (6), directly beats on the buffer plate (9), slides on the conveying rotating roller (21) after being buffered by the buffer spring (11), slides downwards to one side of the material blocking rotating plate (27) along the inclined conveying rotating roller (21), and stops leaking from the inner structure of the material storage mechanism (1);
step three: feeding metal bar materials according to the requirement of a die casting machine, driving a rotating screw rod (17) to rotate by a first driving motor (18), sliding a sliding block (22) along a rectangular sliding groove (16) under the action of threads until a tip part (31) is positioned between two metal bars, keeping the metal bar materials between a material blocking vertical plate (30) and a material blocking rotating plate (27) in a required amount, extending an output rod of a first driving oil cylinder (28) to push a connecting horizontal plate (29) and the material blocking vertical plate (30) to move downwards, and inserting the tip part (31) between the two metal bars;
step four: an output rod of the second driving oil cylinder (35) extends to push the feeding mechanism (5) to rotate by taking the central rotating shaft (33) as a circle center, the feeding mechanism (5) further inclines, the second driving motor (25) drives the material blocking rotating shaft (26) to rotate, the material blocking rotating plate (27) is opened outwards, the metal bar slides to an opening of a metal melting part of the die casting machine, the second driving motor (25) drives the material blocking rotating shaft (26) to rotate, and the material blocking rotating plate (27) rotates inwards to reset;
step five: the output rod of the first driving oil cylinder (28) contracts to drive the connecting horizontal plate (29) and the material blocking vertical plate (30) to move upwards, the metal bar slides to one side of the material blocking rotating plate (27) again, the first driving motor (18) acts again, and the needed metal bar material is cut again;
step six: feeding of all metal bars at the upper end of the conveying rotating roller (21) is completed, an output rod of the second driving oil cylinder (35) contracts to push the feeding mechanism (5) to rotate by taking the central rotating shaft (33) as a circle center, the inclination angle of the feeding mechanism (5) is reduced, and the metal bars are leaked out again by the inner structure of the material storing mechanism (1).
