<p>An injection molding machine includes a cylinder (41) that heats a molding material to be filled into a mold unit, a cooling block (44) that cools a molding material supply port (41a) of the cylinder (41), and a cooling gas supply part (45) that blows cooling gas for cooling the cooling block (44). A blow direction of the cooling gas that is blown from the cooling gas supply part (45) is perpendicular or diagonal with respect to a flow direction of the cooling gas that flows along the cooling block (44).</p> |
