At this time, under the action of the first guide rod, the first movable plate can be made to move vertically up and down along the surface of the first threaded rod, thereby driving the connecting plate at one end and the second mounting plate to move accordingly, until the second mounting plate contacts the surface of the bottom plate, stop the rotation of the first driving motor, and at this time, the sealing cap tube can be placed inside the shaping mold, and then under the action of the expansion mechanism, the sealing cap tube can be effectively placed inside the shaping mold to complete the automatic expansion effect.

[0014] 2. By starting the motor to drive the screw to rotate, under the action of the slider and the limit rod, the threaded plate can move vertically up and down along the surface of the screw, thereby driving the threaded plate to slowly move up along the surface of the screw, so that the top plate slowly moves up inside the shaping mold until the shaped sealing tube is slowly pushed out of the shaping mold. This setting can effectively remove the sealing tube after expansion, prevent the sealing tube from sticking to the shaping mold during use, affecting the production quality of the sealing tube, and quickly expand the next sealing tube, thereby improving the overall production efficiency and production quality of the equipment.
