An extrusion channel of the mold comprises a downward pressing section, a radial extrusion section and a forming section which are equal in flow, the radial extrusion section is obtained through accurate calculation of a mathematical model, and the flow of the downward pressing section, the flow of the radial extrusion section and the flow of the forming section are gradually reduced; the ejection block is arranged at the bottom of the female die and moves upwards along the axis to eject the formed part so that the formed part can be demolded, and a flow dividing structure protruding out of the bottom face of the female die is arranged on the ejection block. The invention further discloses an annular cylinder piece forming method. According to the extrusion channel, the stress state during forming of the annular cylinder part can be effectively improved, the compactness is improved, and the risk of deformation and cracking is reduced; by means of the flow dividing structure arranged on ...
