Positioning jacking-out device used for punching mold

The utility model discloses a positioning jacking-out device used for a punching mold. The positioning jacking-out device comprises a jacking mechanism, a material supporting plate, positioning jacking-out blocks, a lower mold seat and a guide rod, wherein the bottom surface of the material supporting plate is arranged on the jacking mechanism, the jacking mechanism can jack up or put down the material supporting plate, the positioning jacking-out blocks are respectively arranged at the two ends of the top surface of the material jacking plate, the lower mold seat is arranged at the lower end of the jacking mechanism and is detachably connected with the punching mold, the guide rod passes through the lower mold seat to be connected with the material supporting plate. The positioning jacking-out device has the advantages that the two-way positioning and flanging are realized through positioning jacking-out mechanisms arranged at the two ends of the material supporting plate, and the occupation on the space can be reduced. The two-way positioning and flanging are realized, so that the use number of the positioning jacking-out devices can be reduced, the installing and debugging time of the mold is reduced, the damage possibility of the material support plate is reduced, and the service life of the mold is prolonged. In addition, through the dismounting connection between the lower mold seat and the punching mold, the positioning jacking-out device can be selected according to punching molds in different dimensions, and the installation and the repair of the positioning jacking-out devices are convenient.
