<p>PROBLEM TO BE SOLVED: To provide a small-sized injection molding machine capable of handling an ordinary-sized resin material.SOLUTION: An injection molding machine 1 includes a cylindrical cylinder 10 having a raw material supply port 12 from which a resin material 30 is supplied, and a screw 20 rotatable in the cylinder 10. The resin material 30 supplied from the raw material supply port 12 is plasticized by the rotation of the screw 20. Crushing blades 24 are formed at the base end side of the screw 20. The resin material 30 supplied from the raw material supply port 12 to the cylinder 10 when the screw 20 rotates is caught in between an edge of the raw material supply port 12 and the crushing blades 24 and crushed.</p> |
