When the mold trolley 5 collides with the baffle plate 505, the lifting cylinder 520 raises the limit column 521 to fix the mold frame 9, so as to prevent the mold frame 9 from moving in series when the mold changing trolley 5 moves, and the speed reducer 1 504 acts in reverse, so that The mold changing trolley 5 reversely moves to directly below the lifting frame 806, and the motor 1107 on a mold base library 11 moves, driving the chain three 1103 to push the moving frame to move to the mold changing trolley 5, the hook two 1106 hooks the mold base 9, and the motor 1107 Reverse action, moving frame 2 1102 pulls formwork 9 to formwork guide rail 2 1104, another motor 1107 on the formwork warehouse 11 moves, moving frame 2 1102 pushes new formwork 9 to the mold changing trolley 5 Move in the same direction, place the new formwork 9 on the mold changing trolley 5, the speed reducer 1 504 moves, so that the mold changing trolley 5 moves to the bottom of the transport plate 714, and place the new formwork 9 on the transport plate 714, The linear driver 702 drives the vertical support seat 701 to move to the left. When the transport plate 714 moves horizontally to the front of the press table 1 on the left, the new formwork 9 is replaced in the press, and the press can start working immediately; Simultaneously with the mold base 9, the lifting hydraulic cylinder 801 acts and drives the lifting frame 806 to descend. When the lifting frame 806 is close to the upper mold base, the lifting frame 806 and the upper mold base are fastened together, and the lifting hydraulic cylinder 801 acts in reverse. , drive the lifting frame 806 to move up, and when it moves up to a suitable position, the lifting hydraulic cylinder 801 stops, and the lifting frame 806 is still; another transmission device 7 moves, and a new mold core is placed on the transport plate 714, and the joint arm 710 is bent. The transport plate 714 is placed directly below the upper mold frame, and the lifting rod of the lifting hydraulic cylinder 718 is continuously stretched out, and the lifting hydraulic cylinder 718 drives the vertical sliding seat 715 to slide upward along the vertical guide rail 705, and a new mold core is replaced on the upper mold frame. On the formwork, the joint arm 710 can be bent to the outside of the elevator, and the lifting hydraulic cylinder 801 drives the lifting frame 806 to move down until the upper formwork and the lower formwork cooperate again, thereby completing the mold change, and the replaced formwork 9 is to be lowered The present invention can complete the transmission of the mold frame 9 in the workbench 1 of different presses according to the actual needs through the setting of the transmission device 7, and the mold changing trolley 5 can automatically move and transport the mold frame 9, which has a high degree of automation and improves the mold changing process. Efficiency, the setting of the mold base library 11 realizes the replacement of the new mold base 9, and transports the new mold base 9 to the press while replacing the mold core, further improving the efficiency of mold change; the present invention can be applied to the mold base 9 in the press replacement work.
