DETAILED DESCRIPTION

[0014] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0015] like Figure 1It is a structural schematic diagram of the utility model, a punching machine for color-coated plates, the punching machine comprises a frame 1 and a workbench 2, a hydraulic pump 3 and a punching plate 4 mounted on the frame 1, the punching plate 4 is used for the installation of the punching head, the punching plate 4 is located above the workbench 2, the output end of the hydraulic pump 3 is fixedly connected to the punching plate 4, the hydraulic pump 3 can be replaced by a hydraulic cylinder, and the application does not make specific restrictions on this. A card slot 21 for fixing the mold 5 is provided on the top surface of the workbench 2, and a receiving groove 22 is provided on the bottom surface of the card slot 21. The design of the card slot 21 facilitates the direct sliding installation of the mold and can realize the lateral limiting effect on the mold. The card slot 21 is an inverted T-shaped structure, and the card slot 21 matches the bottom of the mold 5.

[0016] like Figure 1 , Figure 2 As shown, a first fixing assembly 6 is arranged in the receiving groove 22, and the first fixing assembly 6 includes a lifting block 61 elastically arranged in the receiving groove 22, and the lifting block 61 is slidably connected to the receiving groove 22. The lifting block 61 has an introduction surface, which is convenient for the mold to slide directly into so that the lifting block 61 retracts into the receiving groove 22. A limiting groove 51 is provided on the bottom surface of the mold 5. When the mold 5 is installed on the workbench 2, the upper part of the lifting block 61 is located in the limiting groove 51. Through the cooperation of the first fixing assembly 6 and the slot 21, the vertical and longitudinal limiting of the mold is realized. The first fixing assembly 6 is provided with a plurality of guide surfaces, and the mold 5 is provided with a plurality of guide surfaces. The component 6 includes an elastic element 62 and a pull rod 63. The elastic element 62 is located in the receiving groove 22. One end of the elastic element 62 abuts against the lifting block 61, and the other end abuts against the receiving groove 22. The elastic element 62 provides elastic potential energy to make the lifting block 61 enter the limiting groove 51. In the initial state, the top surface of the lifting block 61 is higher than the bottom surface of the slot 21. One end of the pull rod 63 is fixedly connected to the lifting block 61, and the other end passes through the workbench 2. When the mold needs to be replaced, the pull rod 63 is pulled to make the lifting block 61 drop out of the limiting groove 51, thereby releasing the lock of the first fixed component 6.

[0017] like Figure 1 , Figure 2 As shown, there are two guide pillars 7, so that both ends of the mold 5 have a second fixing component 8, which further fixes the mold firmly and balances the fixing force to avoid unilateral warping.

[0018] like Figure 1 , Figure 2As shown, a guide column 7 is installed on the top surface of the workbench 2, and a second fixing component 8 is arranged on the guide column 7. The second fixing component 8 includes a sliding sleeve 81 and a fixing block 82. The sliding sleeve 81 is slidably installed on the guide column 7, and the fixing block 82 is rotatably connected to the sliding sleeve 81. The fixing block 82 has a stepped docking surface, and the mold 5 has a fixing groove 52 matching the fixing block 82. Through the cooperation of the second fixing component 8, the card slot 21 and the first fixing component 6, the limitation of the mold is further improved, which is convenient for the user to assemble directly. The sliding sleeve 81 is moved up and the fixing block 82 is rotated to make it disengage from the fixing groove 52, thereby releasing the lock of the second fixing component 8. The fixing groove 52 of the mold 5 is located in the middle of the mold 5, and the front and rear sides of the fixing groove 52 have side walls, and there is no moving space for the fixing block 82 along the sliding direction of the mold 5.

[0019] A plurality of bolts 9 are installed on the workbench 2, and the bolts 9 are threadedly connected to the mold 5. The connection strength is enhanced by installing the threaded connector.

[0020] When in use, the mold slides into the slot 21, and the lifting block 61 enters the accommodating groove 22 through the introduction surface or the pull rod 63 to avoid the mold, until the limiting groove 51 moves to the top of the lifting block 61, and then enters the limiting groove 51 under the elastic force of the elastic element 62, and the fixing block 82 enters the fixing groove 52 by moving the sliding sleeve 81, and finally fixed with bolts 9 to complete the docking installation of the mold.

[0021] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
