The present application will be further described with reference to the following drawings and specific embodiments.

Please refer to fig. 1 to 7, a pin puller capable of rapidly removing a mold includes a force-bearing rod 1, a force-borrowing cylinder 2 sleeved on the force-bearing rod 1 and capable of sliding back and forth along the force-bearing rod, and a limiting mechanism 3 for connecting between a mold to be removed and the force-bearing rod 1 to prevent the force-borrowing cylinder from separating from the force-bearing rod, wherein the force-borrowing cylinder 2 slides along the force-bearing rod 1 to knock the end of the force-bearing rod to force a part in the mold to separate from the mold. Specifically, the tip of atress pole 1 is equipped with atress head 11, borrow a power section of thick bamboo 2 and be close to the one end of atress head 11 is equipped with the head of knocking of atress head 11.

This application embodiment, thereby borrow a power section of thick bamboo and can slide along the atress pole and strike the part in the tip of atress pole and break away from the mould in forcing the mould, stop gear is used for connecting between mould and the atress pole that awaits measuring, can make borrow a power section of thick bamboo and can only make a round trip to slide on the atress pole, prevent that it breaks away from the atress pole, thereby utilize borrow the effort that a power section of thick bamboo slides and produce and strike the cup head position drive part of atress pole, make it break away from the mould, the dismantlement process is light swift.

Further, the limiting mechanism 3 comprises a limiting barrel 31, a threaded connector 32 and an exchangeable bolt 33, the threaded connector 32 is arranged at one end of the limiting barrel 31 adjacent to the stress rod 1 and is in threaded connection with the stress rod, and the exchangeable bolt 33 is arranged at one end of the limiting barrel 31 adjacent to the mold and is in threaded connection with the mold. In this embodiment, the threaded connector is an M8 screw, one end of which is clamped in the limiting cylinder, and the other end of which extends out of the limiting cylinder and is in threaded connection with the stress rod.

Furthermore, a mounting hole 311 penetrating through two ends of the limiting cylinder is formed in the limiting cylinder 31, a step part 312 is formed in the mounting hole 311, one end of the threaded connector 32 extends out of the mounting hole 311, a connecting thread 321 is formed at the extending end, the other end of the threaded connector 32 is clamped on the step part 312, and a screw hole 12 connected with the connecting thread is formed in the end face, corresponding to the connecting thread 321, of the stress rod 1.
