[0055] The drive cylinder in the second demolding drive mechanism 7 drives the second demolding connecting rod 71 to move forward, and in the process of moving forward, the second demolding connecting rod 71 drives the adapter drive frame 8 to rotate around the connecting shaft in the second rotary point 83. In this process, the adapter drive frame 8 drives the first slider assembly 4 to retreat away from the sealing strip along the sliding groove of the two limiting plates 131, and at the same time, the second demolding connecting rod 71 drives the second slider assembly 5 to retreat away from the sealing strip to the limit position of the second limiting sliding groove 921, and then the second slider assembly 5 drives the sliding limiting rotary plate 92 to rotate away from the sealing strip around the 1221 rotary point;

[0056] The driving cylinder on the first demolding driving mechanism 6 drives the first demolding connecting rod 61 to move forward, and the first demolding connecting rod 61 drives the adapter assembly 601 to retreat to the side away from the sealing strip during the movement, and the adapter assembly 601 first contacts the lower plug plate assembly 31 during the retreat, and drives the slider 301 in the lower plug plate assembly 31 to retreat together in the plug plate sliding limiting assembly 34 and the sliding limiting block 39, and the lower plug plate assembly 31 drives the guide inclined jacking block 36 to contact the roller assembly 351 on the outer side of the upper plug plate assembly 33 during the retreat, and the guide inclined jacking block 36 applies an upward force to the roller assembly 351 through the inclined jacking surface thereon, and the middle plug plate assembly 32 and the upper plug plate assembly 33 are pre-lifted through the power connecting block 35;

[0057] The adapter assembly 601 drives the lower plug plate assembly 31 to retreat a distance and then contacts the middle plug plate assembly 32, and drives the lower plug plate assembly 31 and the middle plug plate assembly 32 to retreat together until the jacking rod 322 in the middle plug plate assembly 32 contacts the inclined jacking surface 341 on the plug plate sliding limiting assembly 34, and then the middle plug plate assembly 32 and the upper plug plate assembly 33 are gradually lifted through the jacking rod 322 during the retreat of the middle plug plate assembly 32 under the reaction force of the inclined jacking surface 341, and the roller assembly 351 also moves upward along the guide inclined jacking block 36 to further apply an upward force, until the jacking rod 322 completely passes through the inclined jacking surface 341 and the lifting is completed.

[0058] When the power transmission key 323 on the middle plug plate assembly 32 retreats until it abuts against the power connecting block 35 during the retreat of the lower plug plate assembly 31 and the middle plug plate assembly 32 driven by the second adapter block 601, the middle plug plate assembly 32 drives the upper plug plate assembly 33 to retreat together until reaching the demolding position.

[0059] The above only describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make several improvements without departing from the principles of the present application, and these improvements should also be considered as the protection scope of the present application.
