At this time, negative pressure will be formed in the rodless cavity of the air groove 15, so that the lower mold 1 is firmly adsorbed on the table of the punching machine. After the pressing plate 17 is rotated to a certain extent, the pressing plate 17 will be stuck by the clamping plate 110, making it difficult for the pressing plate 17 and the bolt 16 to rebound. Then the upper mold 12 and the pressing assembly of the punching machine are connected by the connecting piece 13 to complete the installation of the mold. When the mold needs to be disassembled, the connection between the connecting piece 13 and the pressing assembly of the punching machine is released, and then the clamping plate 110 is moved to release the restriction on the pressing plate 17. The bolt 16 will slide downward under the action of negative pressure, so that negative pressure is no longer formed inside the air groove 15, so that the mold can be conveniently removed from the table of the punching machine for replacement. Through the above structure, there is no need to use bolts to fix the mold, which reduces the occurrence of bolt rust, and the mold can be disassembled and assembled conveniently and quickly.

[0024] like Figures 1 to 4As shown, the side wall of the lower mold 1 is symmetrically arranged with multiple slide grooves 2; the middle part of the slide groove 2 is slidably connected to a top plate 21; the bottom of the side wall of the top plate 21 is fixedly connected to an elastic plate 22; the side of the elastic plate 22 facing the top plate 21 is fixedly connected to a limiting block 23; the top of the elastic plate 22 is fixedly connected to a first hook 24; the bottom of the side wall of the connecting member 13 is fixedly connected to multiple fixed plates 25; the fixed plate 25 is arranged above the multiple elastic plates 22; the bottom of the side wall of the fixed plate 25 is fixedly connected to a second hook 26; during operation, when stamping the automobile panel, the edge of the stamping raw material is located above the top plate 21, and when the upper mold 12 descends for stamping, the fixed plate 25 will extend between the side wall of the lower mold 1 and the elastic plate 22, and when it is completed After the automobile panel is stamped, the upper mold 12 will rise. At this time, the first hook 24 and the second hook 26 will be staggered and stuck to each other, so that the elastic plate 22 and the top plate 21 will rise together with the upper mold 12. At this time, the rising top plate 21 will lift the stamping part stuck on the lower mold 1. After moving to a certain height, the limit block 23 will be blocked by the top of the slide groove 2, so that the elastic plate 22 will produce elastic deformation in the direction away from the top plate 21, so that the limit block 23 and the fixed plate 25 are no longer stuck to each other, and the top plate 21 and the stamping part fall down. Through the above structure, when the automobile panel is stamped and stuck on the lower mold 1, the stamping part stuck on the lower mold 1 can be automatically peeled off, thereby facilitating the transfer of the automobile panel stamping parts and improving the convenience of the device.

[0025] like Figures 1 to 5 As shown, a plurality of liquid passing grooves 3 are provided in the middle of the lower mold 1; the plurality of liquid passing grooves 3 are connected to the mold pit above the lower mold 1; mounting grooves 31 are provided on both sides of the lower mold 1; a collecting box 32 is detachably installed in the middle of the mounting groove 31; during operation, before stamping, it is necessary to spray lubricating liquid on the top of the lower mold 1, so as to reduce the friction between the lower mold 1 and the stamping part and improve the service life of the lower mold 1. At this time, excess lubricating liquid will flow along the plurality of liquid passing grooves 3 to the inside of the collecting box 32, so as to reduce the residual lubricating liquid in the mold groove above the lower mold 1, thereby reducing the influence of the residual lubricating liquid on the stamping accuracy, and the excess lubricating liquid can be collected to reduce the waste of lubricating liquid.

[0026] like Figures 1 to 5 As shown, a fixed frame 4 is fixedly connected to the middle of the liquid passage groove 3; a filter plate 41 is fixedly connected to the middle of the fixed frame 4; when the lubricating liquid flows out from the end of the liquid passage groove 3, the lubricating liquid first falls on the top of the filter plate 41, and at this time, the impurities in the lubricating liquid will be filtered by the filter plate 41, so that the relatively clean lubricating liquid passes through the filter plate 41 and falls into the interior of the collecting box 32, thereby reducing the influence of impurities on the use effect when the lubricating liquid is reused.

[0027] like Figure 1 to Figure 2As shown, a pull rope 5 is fixedly connected to the side wall of the card plate 110; the other end of the pull rope 5 is fixedly connected to a pull ring 51; through the above structure, the card plate 110 can be easily pulled, thereby quickly releasing the restriction of the card plate 110 on the pressing plate 17, thereby improving the convenience of use of the device.

[0028] like Figures 1 to 3 As shown, a plurality of magnets 6 are fixedly connected to the bottom of the lower mold 1; the bottom surfaces of the plurality of magnets 6 are arranged higher than the bottom surface of the rubber pad 14; during operation, after the lower mold 1 is placed on the table of the punching machine, the magnets 6 will be adsorbed toward the metal table of the punching machine, so that the rubber pad 14 and the table of the punching machine fit more closely, thereby reducing the occurrence of external gas entering the air groove 15 when the pressing plate 17 is rotated.

[0030] During operation, the mold is placed on the table of the punching machine. At this time, the rubber pad 14 will fit with the table of the punching machine, and then the pressing plate 17 is rotated. The top of the support frame 19 is used as a fulcrum by using the lever principle to drive a pair of bolts 16 to rise. At this time, negative pressure will be formed in the rodless cavity of the air groove 15, so that the lower mold 1 is firmly adsorbed on the table of the punching machine. After the pressing plate 17 is rotated to a certain extent, the pressing plate 17 will be stuck by the clamping plate 110, so that the pressing plate 17 and the bolts 16 are difficult to rebound, and then the upper mold 12 and the lower pressing assembly of the punching machine are connected by the connecting piece 13. The mold is connected to the upper plate 21 to complete the installation of the mold. When the mold needs to be disassembled, the connection between the connecting member 13 and the pressing assembly of the punching machine is released, and then the card plate 110 is toggled to release the restriction on the pressing plate 17. The bolt 16 will slide downward under the action of the negative pressure, so that the negative pressure is no longer formed inside the air groove 15, so that the mold can be easily removed from the punching machine table for replacement. When punching the automobile panel, the edge of the punching part raw material is located above the top plate 21. When the upper mold 12 is lowered for punching, the fixing plate 25 will extend into the side of the lower mold 1. The upper mold 12 is between the wall and the elastic plate 22. After the stamping of the automobile panel is completed, the upper mold 12 will rise. At this time, the first hook 24 and the second hook 26 will be staggered and stuck to each other, so that the elastic plate 22 and the top plate 21 will rise together with the upper mold 12. At this time, the rising top plate 21 will lift the stamping part stuck on the lower mold 1. After moving to a certain height, the limit block 23 will be blocked by the top of the slide 2, so that the elastic plate 22 will produce elastic deformation in the direction away from the top plate 21, so that the limit block 23 and the fixed plate 25 are no longer stuck to each other, so that the top plate 21 As the stamping parts fall, before stamping, it is necessary to spray lubricating liquid on the top of the lower mold 1 to reduce the friction between the lower mold 1 and the stamping parts and improve the service life of the lower mold 1. At this time, excess lubricating liquid will flow along the multiple liquid grooves 3 to the inside of the collecting box 32, thereby reducing the residual lubricating liquid in the mold groove above the lower mold 1, and the excess lubricating liquid can be collected. After placing the lower mold 1 on the table of the stamping machine, the magnet 6 will be adsorbed toward the metal table of the stamping machine, so that the rubber pad 14 fits more closely with the table of the stamping machine.
