The operation principle of the jig 100 of the present invention: the push mold motor M is started under the control of the control cabinet 4, and pushes the push device 2 along the chain guide 1 to the direction of the exchange bottom plate 200 placed on the punching bed, that is, forwards in the pushing process. When the chamfered surface 232 of the latching member 23 hits the sloped surface 32 of the latching block 3, it automatically slides along the sloped surface 32, even if the latching portion 231 rises until the latching portion 231 is inserted into the socket 31, That is, the pushing device 2 snaps the card block 3, and the in-position sensor 41 senses the sensing point 71 to be triggered, and the in-position sensor 41 transmits the triggered information to the control cabinet 4, and the control cabinet 4 controls the pushing die motor M. Stop pushing forward of the pushing device 2, and reversely changing to backward movement to pull out the exchange bottom plate 200 on which the mold to be laid off is placed; when the exchange bottom plate 200 on which the mold to be laid is placed is pulled out of the punching table by the pushing device 2 And moving to the shifting arm, and the pushing device 2 is pulled onto the zipper rail 1, when the first in-position sensor 42 senses the sensing point 71 and is triggered, the in-position sensor 42 transmits the triggered information to the control cabinet 4 , control cabinet 4 controls the push mold horse M stops running, stopped pusher 2 is moved in the chain guide 61, the release plate 24 the vertical edge 242 of the sliding block 6 is inserted immediately (provided in the top of the cylinder 52) 61 in the notch, Then, the control cabinet 4 controls the ejector cylinder 52 to lift the sliding block 6 upward, and the trip plate 24 is lifted up synchronously with the sliding block 6 to lift the latching member 23 upward until the latching portion 231 is completely separated from the socket 31. That is, the pushing device 2 releases the buckle of the snap block 3; after that, the push die motor M is restarted under the control of the control cabinet 4, and the push device 2 is along the chain guide 1 to the direction of the exchange substrate 200 on which the die to be wound is mounted. That is, pushing forward, and during the pushing process, the buckle portion 231 is inserted into the socket 31, the pushing device 2 snaps the snap block 3, and then the pushing device 2 pushes the exchange substrate 200 with the mold to be loaded onto the punching machine (not shown). ), until the exchange bottom plate 200 is pushed onto the punching table, when the in-position sensor 41 senses the sensing point 71 and is triggered, the in-position sensor 41 transmits the triggered information to the control cabinet 4, and the control cabinet 4 controls the pushing mold. The motor M stops running, the pushing device 2 stops moving on the chain guide rail 1, and the vertical side 242 of the trip plate 24 is just inserted into the notch 61 of the sliding block 6 (disposed on the ejection cylinder 51), and the control cabinet 4 Controlling the ejector cylinder 51 to lift the sliding block 6 upwards The plate 24 is lifted up synchronously with the sliding block 6 to lift the latching member 23 upward until the latching portion 231 is completely disengaged from the socket 31, that is, the pushing device 2 releases the latching of the latching block 3; finally, the control cabinet 4 controls the pushing The mold motor M reversely drives the pushing device 2 to move backward until it returns to the origin, that is, the tail end of the chain guide 1; thereby completing the operation of pulling the mold to be pulled out from the punching table and pushing the mold to be pushed onto the punching table.

In summary, the jig for mold change of the punching machine of the present invention can mechanically and automatically pull the mold to be laid out from the punching table surface, and push the mold to be loaded onto the punching table surface, thereby improving the operation efficiency and solving the problem. The safety hazard of manual work.
