Patent ID: 8235692

Claim:
A nozzle structure for spraying a lubricant at least toward a tip of a punch prior to filling a powder material in a compression molding machine that compresses, using the punch, the powder material filled into dies to manufacture a compressively molded product, the nozzle structure comprising: a guide path that guides the lubricant; a spraying portion that is provided above an uppermost surface of the guide path so as to communicate therewith, and that sprays the lubricant guided along the guide path so as to be substantially aligned with a predetermined straight line intersecting at least in a direction of a relative displacement of the punch, the spraying portion comprising a groove whose longitudinal direction is formed substantially perpendicular to a trajectory of centers of the dies; a through hole that inflects from the uppermost surface of the guide path perpendicular to a direction of an extension of the guide path to connect a bottom surface of the groove to the uppermost surface of the guide path; and an electrode comprising a tip portion exposed inside the through hole, said tip portion of the electrode being located below the bottom surface of the groove and above the uppermost surface of the guide path.
