The invention provides an injection molding machine which can restrain thermal degradation of a molding material. The injection molding machine is provided with a cylinder body (11); a material feeding device (81) for feeding the molding material into the cylinder body (11); a threaded rod (20) configured to freely rotate in the cylinder body (11) and proceed or step back freely along the axial direction; and a driving device (60) for driving the threaded rod (20). The material feeding device (81) feeds the molding materials equivalent to one dosage into the cylinder body (11) every other molding cycle. |
