Both the limiting ring 74 and the connecting plate 75 are in contact with the stabilizing frame 711. The assembly plate 79 corresponds to the slider 72.

[0033] Meanwhile, pull the grip rod 710, and make the grip rod 710 drive the pin 78 to move through the assembly plate 79, so that the pin 78 moves out of the inner side of the limiting hole 77. Then, pull up the upper mold 8, so that the upper mold 8 drives the slider 72 to slide inside the stabilizing frame 711 through the docking plate 76, and make the slider 72 slide upward along the control rod 73. At the same time, drive the limiting ring 74 and the connecting plate 75 to move upward. And through the slider 72 sliding upward along the control rod 73, the limiting ring 74 and the connecting plate 75 sliding upward, so that the upper mold 8 can move upward smoothly. At this time, make the slider 72 contact the inner top of the stabilizing frame 711. Then, insert the pin 78 into the inner side of the limiting hole 77, and make the pin 78 located below the slider 72, so that the pin 78 limits the position of the slider 72. By the slider 72 sliding along the control rod 73, and making the limiting ring 74 and the connecting plate 75 move closely against the stabilizing frame 711, the purpose of facilitating the smooth movement of the slider 72 inside the stabilizing frame 711 can be achieved, and the slider 72 can drive the docking plate 76 to move upward stably. At the same time, insert the pin 78 into the inner side of the limiting hole 77, and make the slider 72 contact the pin 78, so as to facilitate the limitation of the height of the slider 72, so that the slider 72 remains stationary.

[0034] The lower end of the lower mold 1 is fixedly connected to a base 5. The front end of the docking plate 76 is fixedly connected to an upper mold 8. An injection hole 9 is opened at the upper end of the upper mold 8. The upper mold 8 corresponds to the lower mold 1, and the injection hole 9 corresponds to the injection inner shell 4.

[0035] Through the function of the base 5, the purpose of facilitating the support of the lower mold 1 can be achieved.

[0036] Working principle: During replacement, the worker first pulls the grip rod 710, and makes the grip rod 710 drive the bolt 78 to move through the assembly plate 79, so that the bolt 78 moves out of the inner side of the limiting hole 77. Then, the upper mold 8 is pulled upward, so that the upper mold 8 drives the slider 72 to slide inside the stabilizing frame 711 through the docking plate 76, and makes the slider 72 slide upward along the control rod 73. At the same time, the limiting ring 74 and the connecting plate 75 are driven to move upward. And through the slider 72 sliding upward along the control rod 73, the limiting ring 74 and the connecting plate 75 sliding upward, the upper mold 8 can move upward smoothly. At this time, the slider 72 contacts the inner top of the stabilizing frame 711. Then, the bolt 78 is inserted into the inner side of the limiting hole 77, and the bolt 78 is located below the slider 72, so that the bolt 78 limits the position of the slider 72. By the slider 72 sliding along the control rod 73, and making the limiting ring 74 and the connecting plate 75 move closely along the stabilizing frame 711, the purpose of facilitating the smooth movement of the slider 72 inside the stabilizing frame 711 can be achieved, and the slider 72 can drive the docking plate 76 to move upward stably. At the same time, the bolt 78 is inserted into the inner side of the limiting hole 77, and the slider 72 contacts the bolt 78, which can achieve the purpose of facilitating the limitation of the height of the slider 72, so that the slider 72 remains stationary, thus limiting the position of the upper mold 8. At this time, the knob 6510 is rotated, so that the threaded shaft 652 rotates inside the support frame 6511. At the same time, the pushing block 653 moves downward along the threaded shaft 652, and the pushing block 653 pushes the regulating frame 651 to one side, so that the sliding block 655 slides inside the sliding groove 654, and the pushing block 653 drives the linkage frame 656 to slide downward along the moving block 659, so that the pushing block 653 can push the regulating frame 651 to one side smoothly, and the regulating frame 651 pulls the limiting rod 64 to move. At the same time, the limiting rod 64 drives the sliding rod 69 to slide along the sliding rod 69, and the control frame 68 stretches the spring 610, and the control frame 68 contacts the limiting ring 611, so as to limit the moving distance of the limiting rod 64, thus preventing the excessive movement of the limiting rod 64. Then, the injection inner shell 4 is pulled, and the injection inner shell 4 drives the docking block 66 to move upward, so that the injection inner shell 4 is disengaged from the inner side of the lower mold 1. Then, the knob 6510 is rotated in the reverse direction, so that the pushing block 653 moves upward. At the same time, the spring 610 pulls the control frame 68 to move in the reverse direction under the elastic action, so that the limiting rod 64 moves back to its original position. At this time, a new set of injection inner shells 4 is replaced, and the docking block 66 is placed inside the docking groove 3, and the docking block 66 is located between the two sliding plates 61. Then, the injection inner shell 4 is pressed downward, so that the docking block 66 slides downward inside the docking groove 3. At the same time, the docking block 66 contacts the slope surface of the limiting rod 64, and the docking block 66 pushes the limiting rod 64 to move by means of the slope surface of the limiting rod 64, so that the limiting rod 64 stretches the spring 610 through the control frame 68. At the same time, the docking block 66 moves into the inner side of the limiting frame 62,And make the docking block 66 drive the limiting rod 67 to be stuck inside the limiting hole 63. At the same time, the spring 610 pushes the limiting rod 64 to move in the reverse direction under the elastic action. Therefore, the lower end of the limiting rod 64 contacts the upper end of the docking block 66, so that the limiting rod 64 limits the regulating part 65 inside the limiting frame 62. At the same time, because the limiting rod 67 is stuck inside the limiting hole 63, the injection molded inner shell 4 is accurately installed inside the lower mold 1, thus avoiding the situation that when the upper mold 8 fits on the upper end of the lower mold 1, the injection molded inner shell 4 cannot be in the correct position. By placing the docking block 66 between the two sliding plates 61 and then pressing down the injection molded inner shell 4, the docking block 66 pushes the limiting rod 64 to move by means of the inclined plane of the limiting rod 64, so as to move the docking block 66 inside the limiting frame 62. And the spring 610 pushes the limiting rod 64 to move in the reverse direction under the elastic action, so that the lower end of the limiting rod 64 contacts the docking block 66, which can achieve the purpose of facilitating the limitation of the docking block 66, thus facilitating the installation of a new set of injection molded inner shells 4, and the installation method is simple, avoiding the situation of needing to screw multiple sets of screws. Secondly, by rotating the threaded shaft 652 and making the pushing block 653 move downward, the pushing block 653 pushes the regulating frame 651 to move, and the regulating frame 651 drives the limiting rod 64 to move, so that the limiting rod 64 separates from the surface of the docking block 66, which can achieve the purpose of facilitating the removal of the docking block 66, thus facilitating the replacement of the injection molded inner shell 4, and improving the efficiency of the worker's replacement. And through the sliding block 655 sliding inside the sliding groove 654 and making the pushing block 653 drive the linkage frame 656 to slide downward along the moving block 659, the pushing block 653 can stably push the regulating frame 651 to one side, so as to improve the stability of the overall operation of the pushing block 653, thus ensuring that the pushing block 653 accurately controls the movement of the regulating frame 651, and thus ensuring the stability of disassembling the docking block 66.,
