PROBLEM TO BE SOLVED: To remove burrs and mustaches at the cut face in the remaining part of a gate. SOLUTION: In a multipoint-picked molding 3, a lens 6 is molded to the tip part of a runner 5 formed with a runner shaft part 5a as the center via a gate 4. A control part 27 drives a movement plate moving mechanism 23, and moves a movement plate 15 in such a manner that the lens 6 is placed on a placing stand 11. The control part 27 drives a duct moving mechanism 25, so as to move an air duct 24 to a position at which the lens 6 is pressed down, and controls the driving of an air control part 26 in such a manner that air is sprayed on the lens 6 through the inside of the air duct 24. The control part 27 drives the cutter moving mechanism 21, so as to move a cutter edge 13 from a retreat position to a cut position, and thereafter moves the same to the retreat position once more. The control part 27 moves the movement plate 15 to a cleaning position in the upper part while rotating a cleaning board 17 by a cleaning motor 16. COPYRIGHT: (C)2009,JPO&INPIT |
