After long-term use, when it is necessary to replace the injection molding block 13, hold the rotating block 30 and rotate it to make the screw rod 29 rotate backward inside the convex block 27 through the threaded groove 28. When the screw rod 29 completely rotates out of the inside of the convex block 27 through the threaded groove 28 and completely rotates out of the inside of the injection molding block 13 through the fixing groove 26, then hold the injection molding block 13 and pull it to the right, so that the injection molding block 13 can be completely slid out of the inside of the installation block 24 through the limiting groove 25 and then replaced, thus preventing the situation where tools are needed for disassembly when the injection molding block 13 needs to be replaced. The injection molding block 13 slides inside the installation block 24 through the limiting groove 25, the screw rod 29 rotates inside the convex block 27 through the threaded groove 28, and the screw rod 29 rotates inside the injection molding block 13 through the fixing groove 26, making it more convenient for the screw rod 29 to rotate and avoiding the situation where the screw rod 29 is stuck by the convex block 27 or the injection molding block 13 during use, resulting in the screw rod 29 being unable to continue rotating.

[0037] At least one of the above embodiments of the present utility model can at least achieve the following: when in use, first place the base 1 in the required position, so that the support pad 2 firmly supports the base 1. Then fix the pipeline on the right side of the connector 4. Then start the hydraulic cylinder 9 inside the installation groove 8, so that the sliding plate 10 slides on the surface of the fixed rod 7 through the sliding groove 11. At this time, the sliding plate 10 drives the right side of the fixing plate B6 of the injection molding block 13 to slide towards the left side of the fixing plate A3.
