[0040] Reference Figures 4 to 6 The first base also includes a first bearing 114 for supporting the first screw thread insert 103 and a plurality of springs 115 for assisting the screw thread demoulding.

[0041] Reference Figure 7 The second screw thread module includes a second row 202, a second driving member 201, and second screw thread track inserts 203 of the same number as the first screw thread inserts 103. One end of the second screw thread track insert 203 is connected to the second row 202 and moves back and forth under the drive of the second row 202. The second driving member 201 provides power for the second row 202. A fixing block 204 is installed at the front end of the second row 202 for fixing the second screw thread track insert 203. A third through hole 205 is provided on the fixing block 204 in a direction perpendicular to the second screw thread track insert 203. A second glass bead fixing block 206 is installed in the third through hole 205. A second spiral groove 207 is provided on the surface of the second screw thread track insert 203. A second glass bead 208 is installed at the position where the second glass bead fixing block 206 and the second spiral groove 207 contact. The second screw thread track insert 203 rotates under the joint action of the second glass bead 208 and the second spiral groove 207 to achieve reciprocating motion.

[0042] Continue to refer to Figures 7 and 8 The second screw thread module also includes a screw thread track connecting block 209 and a spiral position insert 210. The spiral position insert 210 is connected to the screw thread track connecting block 209 and is fixed inside the second screw thread track insert 203 through a fixing strip 211.

[0047] Reference Figure 11 to Figure 12 Under the action of the third oil cylinder 301 , the third position 302 separates the inner needle 303 and the outer needle 304 of the sleeve from the inside of the product 4 and buckles them upside down.

[0048] Reference Figure 12 to Figure 13 When the second screw thread module 2 and the third needle shrinking module 3 complete all actions, the first oil cylinder 101 of the first screw thread module 1 drives the first slide 102 to move, and the first screw thread insert 103 rotates along the first spiral groove 112 to separate from the screw thread rubber position of the product 4. The spring 115 in the first slide 102 assists the first screw thread insert 103 to perform the thread stripping movement. After the first oil cylinder 101 moves 25mm, the screw thread is completely separated.

[0049] Reference Figure 13 to Figure 14 The first oil cylinder 101 continues to move to drive the first row insert 106 to separate from the product 4 and then to complete all the mold actions.
