The invention provides a vertical extruding machine which is used for integrating feeding, extruding and heating forming and is high in production efficiency. The vertical extruding machine is especially suitable for producing a PTFE pipe. The vertical extruding machine comprises an outer mould which is fixed on a rack and provided with a center hole, and a core mould, wherein the core mould penetrates through a center hole of the outer mould, a mould cavity is formed between the core mould and the center hole of the outer mould; the mould cavity comprises an upper extruding section and a lower forming section; an induction heater used for heating the outer mould is arranged on the outer periphery of the outer mould of the forming section; a press mould arranged at the outer periphery of the core mould in a sliding manner is arranged above the mould cavity, the press mould is connected with a main drive device used for driving the press mould to slide along the core mould up and down to enter and exit the extruding section, and the core mould is connected with a core mould drive mechanism used for driving the core mould to move in the direction of an axial line.
