[0002] Currently, when assembling a new mold or replacing a worn insert, the original insert must often be removed for reassembly. This can be difficult to remove. Traditionally, the insert has a threaded hole. To remove the insert, a matching threaded rod is screwed into the hole, providing a fulcrum for removal.

[0003] However, the threaded rod can only provide a small fulcrum point, so when pulling out the insert, it takes a lot of force to pull it out. This operation is not only inefficient, but it is also difficult to ensure that the force applied is vertically upward when pulling out the threaded rod, making it more difficult to pull out the insert and the connection between the threaded rod and the insert is prone to breakage.

Two limit rods 10 are fixed on the iron rod 9, and a slide groove 11 for sliding the limit rod 10 is opened on the fixed cylinder 8. The traction assembly is used to drive the iron rod 9 to move in the longitudinal direction. Two moving assemblies are provided on the base plate 1, and the two moving assemblies are used for auxiliary movement of the base plate 1.

[0022] The iron rod 9 is pulled out and inserted into the inside of the card slot 6, so that the iron rod 9 can hook the carrier rod 2. In this way, when the iron rod 9 is driven upward by the traction assembly, the iron rod 9 can drive the carrier rod 2 to move upward accordingly, which not only ensures that the force of the carrier rod 2 is vertically upward, but also makes it more time-saving and labor-saving when the insert is pulled out with the carrier rod 2, and better meets the operational requirements of insert extraction. With the help of the limit rod 10 and the slide groove 11, the iron rod 9 can be prevented from being completely separated from the fixed tube 8.

The worker holds the auxiliary rod 5 and drives the first threaded rod 3 to rotate, so that the first threaded rod 3 is continuously screwed into the inside of the threaded hole, completing the connection between the first threaded rod 3 and the mold insert. Then, the worker turns the knob 26, so that the knob 26 drives the second threaded rod 24 to rotate. The second threaded rod 24 pushes the stop plate 25 downward, forcing the stop plate 25 to rest on the ground. In this way, the stop plate 25 can prevent the rollers 22 from moving further, so that the device can maintain a stable position.

[0029] The rocker 20 is rotated in the reverse direction, so that the rocker 20 pulls the worm 18 to rotate, and the worm 18 drives the worm wheel 17 to rotate, so that the worm wheel 17 pulls the screw rod 14 to drive the iron rod 9 downward in the form of a screw drive, until the iron rod 9 and the lowest slot 6 on the carrier rod 2 are at the same horizontal plane, and the limit rod 10 is used to push the iron rod 9 to extend to the outside of the fixed tube 8, so that the iron rod 9 is inserted into the inside of the slot 6. The magnet 7 can attract the iron rod 9 to ensure that the iron rod 9 will not retract into the inside of the fixed tube 8 on its own. The rocker 20 is rotated in the forward direction, so that the rocker 20 drives the screw rod 14 to pull the iron rod 9 upward in the form of a screw drive, and the iron rod 9 drives the carrier rod 2 upward, so that the carrier rod 2 pulls out the mold insert.
