Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0022] See Figures 1-4This embodiment provides a punching mold for blister packaging, including a lower mold 1 with a groove for accommodating the blister product. A guide post 2 is fixedly connected above the lower mold 1, and an upper mold 3 is movably fitted onto the outer surface of the guide post 2. A protruding structure is provided below the upper mold 3, which inserts into the groove on the lower mold 1. A rubber layer is provided along the outer edge of the protruding structure for fitting the blister product. The upper mold 3 can slide up and down on the outer surface of the guide post 2. A cutting hole 4 is provided at the bottom of the inner surface of the lower mold 1. The cutting hole 4 is through-hole, and a cutting blade 5 is fixedly installed on the inner surface of the cutting hole 4. The cutting blade 5 is annular in shape, with its cutting edge facing upward and protruding from the bottom of the inner surface of the lower mold 1. A tamping assembly 6 is provided above the upper mold 3, including a tamping post 601 that movably passes through the upper mold 3. The upper mold 3 has a through hole for the tamping post 601 to pass through, which is adapted to the cutting blade 5. A top plate 602 is fixedly connected to the upper end of 601. A second rack 603 is fixedly connected to the lower part of the top plate 602. A second gear 604 is meshed with the front of the second rack 603. A first gear 605 is meshed with the front of the second gear 604. The first gear 605 and the second gear 604 are rotatably connected to the outer surface of the upper mold 3. The tamping component 6 also includes a support block 606. The support block 606 is fixedly connected to the outer surface of the lower mold 1. A first rack 607 is fixedly connected above the support block 606. Only one section of teeth is provided on the first rack 607. The first rack 607 meshes with the first gear 605 from the front. A connecting rod 608 is fixedly connected between the first rack 607 and the outer surface of the lower mold 1. There are two of the following components: the second rack 603, the second gear 604, the first gear 605, the support block 606, the first rack 607, and the connecting rod 608. They are symmetrically arranged on the left and right sides of the upper mold 3 and the lower mold 1, respectively.

[0023] In practical use, the aforementioned equipment is first placed under the upper mold 3, and then the push handle 702 is lowered by an external pushing device. At this time, the push handle 702 will drive the support base 701 to lower the upper mold 3 on the guide post 2. As the upper mold 3 lowers, it will push the vacuum-formed product into the lower mold 1. Simultaneously, the lowering of the upper mold 3 will drive the first gear 605 to lower, and the first rack 607 will push the first gear 605 to roll backward. The first gear 605 will drive the second gear 604 to roll forward, and the second gear 604 will drive the second rack 603 to rise. The second rack 603 will drive the top plate 602 to raise the tamping post 601, and the tamping post 601 will retract into the upper mold. Inside mold 3, the cutting tool 5 will work with the through hole at the tamping post 601 to punch holes in the thermoformed product. After punching, the rising of the upper mold 3 will drive the first gear 605 to rise. When the first gear 605 contacts the teeth on the first rack 607, the first rack 607 will push the first gear 605 to roll forward. The first gear 605 will drive the second gear 604 to roll backward. The second gear 604 will drive the second rack 603 to fall. The second rack 603 will drive the top plate 602 to lower the tamping post 601. The tamping post 601 will protrude from below the upper mold 3, thereby tamping the punched part of the thermoformed material on the upper mold 3 and pushing the waste material out of the punch, thus improving the punching quality. Example

[0024] See Figures 1-4 Based on Embodiment 1, a support assembly 7 is provided above the upper mold 3. The support assembly 7 includes a support base 701, which is shaped like a door frame. The support base 701 is fixedly connected to the upper part of the upper mold 3. A push handle 702 is fixedly connected above the support base 701. The push handle 702 is used to connect to an external pushing device. The external pushing device pushes the push handle 702 downward, thereby driving the support base 701 to lower the upper mold 3. An adsorption assembly 8 is provided below the support assembly 7. The adsorption assembly 8 includes... Metal sheet 801, made of iron, is fixedly connected to the top of top plate 602. Adsorption assembly 8 also includes magnet sheet 802, which can attract metal sheet 801. Magnet sheet 802 is fixedly connected to the top of inner surface of support base 701. When top plate 602 rises, magnet sheet 802 will attract metal sheet 801. Magnet sheet 802 and metal sheet 801 are magnetically connected. The magnetic force between magnet sheet 802 and metal sheet 801 can support the various structures in tamping assembly 6.

[0025] In practical use, when the second rack 603 drives the top plate 602 to raise the tamping column 601, the metal sheet 801 will also rise as the top plate 602 rises. When the upper mold 3 descends and the first gear 605 just passes the first rack 607, the top plate 602 will drive the metal sheet 801 to rise and fit against the magnet 802. At this time, the magnet 802 will attract the metal sheet 801, thereby fixing the top plate 602. This prevents the top plate 602 from falling under gravity when the first gear 605 loses support after passing the first rack 607, thus preventing the tamping column 601 from being pushed downwards when the upper mold 3 descends.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
