[0029] A clear and complete description of a punching device of the utility model will be made below in conjunction with the accompanying drawings.

[0030] like Figure 1 As described above, the punching device provided by the utility model includes a base 1, a bottom die mounting seat 2, a die pressing seat 3 and a driving member 4.

[0031] Among them, the surface of the base 1 is installed with a support platform 5 and a gantry 6, and the support platform 5 and the base 1 bracket are supported and fixed by a support rod 7. There are a plurality of bottom mold mounting seats 2, which are evenly installed on the surface of the bottom mold mounting seat 2. The molding seat 3 is located directly above the support platform 5, and an upper mold mounting seat 8 corresponding to the bottom mold mounting seat 2 is installed on its bottom surface. The driving member 4 is installed on the top of the gantry 6, and its driving end is connected to the molding seat 3. The driving member 4 is preferably a driving cylinder.

[0032] When in use, the bottom mold and upper mold of different shapes are respectively installed on the bottom mold mounting seat 2 and the upper mold mounting seat 8, and then the driving member 4 is started to drive the molding seat 3 to drive the molding seat 3 to move to press with the supporting platform 5, and then the punching work is carried out; this device can punch out products of different shapes at one time as needed, effectively improving the punching efficiency and reducing the labor intensity of the staff.

[0033] Specifically, in this embodiment, four groups of bottom mold mounting seats 2 and upper mold mounting seats 8 are preferably provided, and the four groups of bottom mold mounting seats 2 and upper mold mounting seats 8 are distributed in a "cross" shape; Figure 2 As shown, a "cross" shaped slide groove is correspondingly opened on the surface of the supporting platform 5 and the bottom surface of the molding seat 3, and a main bevel gear 10 and a driven bevel gear 11 meshing with the main bevel gear 10 are rotatably connected inside the "cross" shaped slide groove, and the rotating shaft of the driven bevel gear 11 is connected to the side wall of the "cross" shaped slide groove through a ball screw 9, and the bottom mold mounting seat 2 and the upper mold mounting seat 8 are slidably connected to the ball screw 9 through a sliding block 12.

[0034] A driving motor 13 is installed on the top of the molding seat 3, and the driving motor 13 is connected to the main bevel gear 10 in the molding seat 3; at the same time, a positioning column 14 is installed at the bottom of the rotating shaft of the main bevel gear 10 in the molding seat 3, and a positioning groove 15 that matches the positioning column 14 is opened in the middle of the rotating shaft of the main bevel gear 10 in the supporting platform 5.

[0035] When it is necessary to punch films of different sizes, the driving cylinder is started to drive the molding seat 3 downward until the positioning column 14 is engaged with the positioning groove 15, and then the driving motor 13 is started to drive the main bevel gear 10 in the molding seat 3 to rotate. At this time, the main bevel gear 10 in the molding seat 3 drives the main bevel gear 10 in the supporting platform 5 to rotate, and then drives the driven bevel gear 11 meshing with the two to rotate, thereby driving the bottom mold mounting seat 2 and the upper mold mounting seat 8 to slide and change their positions to adapt to the punching of films of different sizes; through the cooperation of the above structure, the present device can perform punching work on films of different sizes, and its functionality is stronger.

[0036] In addition, in this embodiment, an adsorption hole is also provided on the surface of the support platform 5, and a drawer 16 is slidably connected in the adsorption hole. A sliding plate 18 is slidably provided between the support platform 5 and the base 1, and the drawer 16 is mounted on the surface of the sliding plate 18; specifically, the sliding plate 18 is slidably connected to the support rod 7, and a cylindrical spring 17 is sleeved on the outer side of the support rod 7, one end of the cylindrical spring 17 abuts against the sliding plate 18, and the other end abuts against the base 1.

[0037] A lower pressing plate 20 is installed on the side wall of the sliding plate 18, and an upper pressing plate 19 matched with the pressing plate is installed on the side wall of the molding seat 3.

[0038] When the driving cylinder drives the molding seat 3 to press down, the upper pressing plate 19 presses the lower pressing plate 20 to drive the sliding plate 18 downward to evacuate air, thereby adsorbing and fixing the film on the surface of the supporting platform 5, which can effectively prevent the position of the film from changing during the punching process, thereby ensuring the quality of the punched product.
