When polytetrafluoroethylene powder needs to be added between the mold core 405 and the pipe fitting, sufficient polytetrafluoroethylene powder is added into the storage bin 50801 through the feeding hole 50806, two sets of check valves 50807 below the storage bin 50801 are made to move downwards to a gap between the mold core 405 and the pipe fitting through the extension and retraction of the second electric push rod 5023, the third screw 50802 is driven to rotate through the column gear 5022, the third screw 50802 drives the transmission plate 50803 to move downwards, the transmission plate 50803 moves downwards, meanwhile, two sides of the third screw 50802 are provided with a set of sliding sleeve 50804 and sliding rod 50805 combination, the sliding sleeve 50804 slides downwards on the outer surface of the sliding rod 50805 to be matched with the downward movement of the transmission plate 50803, the polytetrafluoroethylene powder is extruded downwards through the transmission plate 50803, the check valves 807 50807 are opened, and the polytetrafluoroethylene powder is sprayed into a gap between the mold core 405 and the pipe fitting, and the polytetrafluoroethylene powder is added through the.

Symmetrical curved through grooves are formed in the limiting disc 5034.

The two sets of collecting plates 5025 can move in the two through grooves of the limiting disc 5034 respectively to move the two sets of collecting plates 5025 away, so that the orientation of the mold core 405 and the pipe fitting can be adjusted under the action of the transfer component 409, and the mold core 405 and the pipe fitting are vertically positioned below the feeding component 508.

The material vibrating hammer 5033 is in the shape of a ball.

Damage to the pipe fitting during hammering can be avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
