<p>The present invention relates to a cylinder for supplying a material for foam-molding, which has an improved structure to shorten the total length of the cylinder while making the cylinder have sufficient extrusion force, and prevent the material for foam-molding from agglomerating inside a cylinder cover to enhance extrusion performance. The cylinder for supplying a material for foam-molding according to the present invention comprises: a cylinder body having a cylindrical shape with one side opened to have an air inlet and a material inlet on the outside and a cylinder rod disposed inside to be capable of moving forward or backward; a cylinder cover connected to the opened one side of the cylinder body; and an inner case member connected to make a gap space inside the cylinder cover, through which air flows and to have a hollow inside through which a material passes and multiple through-holes to introduce air flowing from the air inlet through the gap space to the inside of the inner case member.</p> |
