The implementation principle of embodiment 2 of the present application is as follows: when the embedded block 32 needs to be rotated into the inner cavity and the supporting block 31 and then rotated into the curved groove 12, the driving disc II 39 is rotated to drive the gear II 391 to rotate, and the ejector rod II 355 is driven to slide upwards in the sliding groove II 352, so that the length of the sliding groove II 352 is smaller than that of the sliding groove I351. Then the cylinder drives the driving rod 35 to slide upwards, so that the second hinge shaft 341 is firstly abutted against the bottom of the second sliding groove 352, and the second connecting rod 34 is firstly rotated and then drives the embedded block 32 to rotate into the inner cavity. Then, the driving rod 35 continues to slide up, so that the second link 34 slides in the insertion block 32, and the spring 344 is compressed, so that the first link 33 can slide up along with the driving rod 35 to drive the supporting block 31 to rotate into the curved slot 12.
When drawing of patterns to flexible glue limit 14, the cylinder drives actuating lever 35 gliding for articulated shaft one 331 and articulated shaft two 341 slide in spout one 351, spout two 352 respectively, because the length of spout two 352 is less than spout one 351, articulated shaft two 341 and the roof butt of spout two 352 earlier. The second link 34 first drives the embedded block 32 to rotate out of the inner cavity along with the driving rod 35, and then the first hinge shaft 331 abuts against the top wall of the first sliding slot 351, so that the first link 33 drives the supporting block 31 to rotate out of the bent slot 12. Similarly, the length of the first ejector rod 354 in the first sliding groove 351 can be adjusted by rotating the first driving disk 38, so that the length of the first sliding groove 351 is smaller than that of the second sliding groove 352, the supporting block 31 can be firstly rotated into the bent groove 12 and can be firstly rotated out of the bent groove 12, and the embedded block 32 can act after the supporting block 31 acts. So that the supporting block 31 and the embedded block 32 rotate away from the soft rubber edge 14, the driving source during demoulding of the soft rubber edge 14 is reduced, and the demoulding cost of the soft rubber edge 14 is reduced.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
