Abstract

The utility model relates to a hollow blowing forming discharging synchronizing moving sealing device, which comprises a lifting mechanism and a sealing mechanism, wherein, the lifting mechanism is connected with a lifting rod and actuates and drives the lifting rod to be operated through a driving part, and the sealing mechanism is arranged on the lifting rod. A clamping wheel actuator is arranged on the sealing mechanism, and the edge of the clamping wheel actuator is provided with a detector. An inductor can induce discharging, and two draw rod actuators push draw rods to be convexly extended into a feed opening. Two traverse motion actuators simultaneously draw in a shrinking mode and drive the two draw rod actuators to move toward both sides, so that the two draw rods extended into the feed opening stretch the circular feed opening into the shape of a straight line. The feed opening is started following the clamping wheel actuator to convexly extend a toothed plate to move into a tunnel, the toothed plate drives two clamping wheels to be rotated, and cranks which are connected with one side end of each clamping wheel and are opposite drive a clamping rod to clamp and close the feed opening in the shape of a straight line. Simultaneously, by the rotation of the lifting rod, the whole sealing mechanism moves following the continuous decline of material parts.
