Claim:
An injection molding machine comprising: a nozzle receiving section configured on a fixed metal mold side of a cavity formed of the fixed metal mold and a movable metal mold so as to slightly protrude toward the movable metal mold, a core section facing the nozzle receiving section provided in the movable metal mold in a manner movable forward/backward, an end of the nozzle being placed on substantially the same plane as that of an end of the nozzle receiving section; and a protruding part provided at a position of the core section facing the end of the nozzle that injects melted resin, wherein a gate of the resin injected into the cavity is cut by moving the core section forward and moving backward the nozzle receiving section and the nozzle pressed by the core section which has been moved forward so that the gate cutting causes a film of the resin to remain at the ends of the nozzle receiving section and the nozzle.
