[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0020] like Figures 1 to 3As shown, in this embodiment, a multifunctional punching jig includes an upper die base 1 and a lower die base 2, a lower die base 3 and a side cutting punch 4 are provided on the lower die base 2, a product cutting fixing block 5 is installed on the lower die base 3, the side cutting punch 4 moves along the horizontal direction, and a lower inclined surface 6 is provided on one side of the side cutting punch 4, a push rod 7 is fixed on the upper die base 1, and an upper inclined surface 8 is provided on the lower end of the push rod 7, a side incision 9 is provided on the lower die base 3, the push rod 7 is inserted into the side incision 9, and the upper inclined surface 8 is in sliding contact with the lower inclined surface 6, a film cutting knife 10 is fixed on the upper die base 1, and the lower end of the upper die base 1 is elastically connected to the upper die base 11, and the lower end of the film cutting knife 10 passes through the lower die base 3.

[0021] The product is placed on the lower template 3 and fixed by the product cutting fixing block 5. The upper mold base 1 moves toward the lower mold base 2, and the lower end of the push rod 7 is inserted into the side cut 9 of the lower template 3. At this time, the upper inclined surface 8 begins to contact the lower inclined surface 6. After the inclined surface is squeezed, the side cutting punch 4 is forced to move horizontally to cut the side of the product. The film cutting knife 10 of the upper mold base 1 also passes through the upper template 11 when the upper template 11 is pressed on the lower template 3 to vertically cut the film of the product on the lower template 3. Then the upper mold base 1 rises upward. Under the action of elasticity, the upper template 11 first maintains vertical pressure on the lower template 3. When the push rod 7 leaves the side cut 9, the side cutting punch 4 is reset horizontally, and the film cutting knife 10 also leaves the lower template 3, the upper template 11 leaves the lower template 3 to ensure that the product will not be affected by the moving parts.

[0022] An upper pad 12 is fixed to the lower end of the upper die base 1, and the upper end of the push rod 7 is fixed on the upper pad 12. A first guide column 13 is connected between the upper pad 12 and the upper template 11. Moreover, a downward pressure spring 14 is connected between the upper die base 1 and the upper template 11. The downward pressure spring 14 passes through the upper pad 12. Under the action of the first guide column 13, the upper template 11 can be expanded and contracted by the downward pressure spring 14 to perform stable vertical movement.

[0023] A second guide column 15 is fixed to the lower end of the upper die base 1, and a guide sleeve 16 is installed around the lower die plate 3. The lower end of the second guide column 15 is inserted into the guide sleeve 16. Under the relative action of the second guide column 15 and the guide sleeve 16, the upper die base 1 and the lower die base 2 can be accurately docked, and the cutting position is more precise.

[0024] A limiting column 17 is fixed at the lower end of the upper die base 1, and the lower end of the limiting column 17 contacts the upper surface of the lower die base 2. Under the action of the limiting column 17, the stroke of the upper die base 1 is limited to the extreme position to prevent the product from being crushed.

[0025] A linear bearing 18 is fixed to the side of the upper die base 1, and an optical axis 19 is fixed to the side of the lower die base 2. The optical axis 19 passes through the linear bearing 18 and is slidably connected to the linear bearing 18. When the optical axis 19 and the linear bearing 18 are relative to each other, the upper die base 1 can move downward smoothly and dock onto the lower die base 2.

[0026] A spring cavity is provided on the inner side of the side cutting punch 4, and a cutter spring 20 is provided in the spring cavity. The outer end of the cutter spring 20 is connected to the lower die base 2. When the push rod 7 squeezes the side cutting punch 4, the cutter spring 20 contracts and the side cutting punch 4 side-cuts the product. When the push rod 7 leaves the side incision 9, the cutter spring 20 expands and resets the side cutting punch 4 to facilitate the removal of the product.

[0027] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be included in the scope of protection of the present invention.
