Patent ID: 7909596

Claim:
A resin molding machine, comprising: a press unit including a resin molding die; and a cleaning unit having a cleaning head movable to and away from the resin molding die for cleaning a molding face thereof, wherein the cleaning head includes: an energy ray irradiation section including a plurality of energy ray sources, arranged to form into a plurality of lines for irradiating energy rays to the molding face of the resin molding die; a moving mechanism moving the energy ray irradiation section, along the molding face, so as to scan the molding face; a swinging mechanism swinging the energy ray irradiation section in a direction perpendicular to the scanning direction of the energy ray irradiation section; and a release agent feeding section spraying mist of a release agent toward the molding face; wherein the energy ray sources, which are arranged to form into the plurality of lines, are mutually shifted in a direction perpendicular to the scanning direction of the energy ray irradiation section; and wherein the energy ray irradiation section scans the molding face with irradiating energy rays and the swinging mechanism swings the energy ray irradiation section, which is scanning with irradiating energy rays, in the direction perpendicular to the scanning direction without changing a distance to the molding face when the cleaning unit enters the molding die, the release agent feeding section sprays mist of the release agent when the cleaning unit returns, every time one or a plurality of the resin molding actions are performed, thereby the contamination of the molding die is stuck onto resin of a molded product when the next product is resin-molded, so that the next molded product is released from the resin molding die together with the contamination.
