[0012] Optionally, two connecting rods are provided along the axial direction of the eccentric shaft and are respectively hinged to opposite sides of the floating plate.

[0013] Optionally, at least two groups of the elbow rods are spaced apart in the arrangement direction of the connecting rods.

[0014] Optionally, the frame further comprises an intermediate plate fixed between the top plate and the bottom plate and a guide rod connected to the intermediate plate;

[0034] Please also read Figures 1 to 4 Now, a double-elbow lever force-enhancing aluminum-plastic aluminum-aluminum blister forming device provided in the embodiment of the present application is described. The double-elbow lever force-enhancing aluminum-plastic aluminum-aluminum blister forming device comprises a frame, a mold assembly, a driving assembly and a force-enhancing assembly. Among them:

[0035] The frame includes a top plate 101 and a bottom plate 102 which are arranged in a spaced-apart manner in the height direction. The mold assembly includes an upper mold base 201 and a lower mold base 202 which are arranged relatively to each other, and the upper mold base 201 is arranged below the top plate 101 and close to the top plate 101. In this embodiment, the upper mold base 201 and the lower mold base 202 are respectively used to install the upper mold and the lower mold required for blister molding. During the blister molding process, the upper mold base 201 and the lower mold base 202 complete the blister molding process by approaching or moving away from each other. The usual upper mold base 201 can be set as a structure fixedly connected to the top plate 101, that is, the upper mold base 201 is a fixed structure, or it can be set as a movable structure in which the upper mold base 201 can move up and down. Both of these structural modes can adopt the existing technology and are not required in this embodiment. The drive assembly includes an eccentric shaft 301 and a connecting rod 302 which is hinged on the eccentric shaft 301 and can be driven by the eccentric shaft 301 to reciprocate in the horizontal direction. The eccentric shaft 301 can be driven by a servo motor. The force-enhancing assembly includes a floating plate 401 hinged on the connecting rod 302 and two elbow rods 402 hinged on the floating plate 401. The ends of the two elbow rods 402 away from the floating plate 401 are hinged on the lower mold base 202 and the bottom plate 102 respectively. The floating plate 401 is horizontally arranged relative to the rotation axes of the connecting rod 302 and the elbow rod 402, and the connecting rod 302 is longer than the elbow rod 402.

[0036] According to the above structure provided in this embodiment, when the eccentric shaft 301 drives the connecting rod 302 to reciprocate in the horizontal direction, the floating plate 401 connected to the connecting rod 302 can also reciprocate in the horizontal direction. In this process, the elbow rod 402 hinged on the floating plate 401 can rotate relative to the floating plate 401 and make the lower mold base 202 and the bottom plate 102 move away from or closer to each other, thereby achieving the technical effect of the upper mold base 201 and the lower mold base 202 moving closer to or away from each other. Since the elbow rod 402 and the connecting rod 302 hinged on the floating plate 401 form a lever structure, when the connecting rod 302 pushes the floating plate 401 to the horizontal front, the corresponding angle of the two elbow rods 402 becomes larger, which produces a force-enhancing effect while pushing the lower mold base 202 to rise, and the length of the connecting rod 302 is longer than the elbow rod 402, so the driving force applied to the connecting rod 302 can make the lower mold base 202 connected to the elbow rod 402 obtain a greater lifting force, so that the double elbow rod force-enhancing aluminum-plastic aluminum-aluminum blister forming device provided in this embodiment has a greater blister forming force, which is far superior to the prior art. In addition, the movement of the connecting rod 302 can be converted into the rotation of the two elbow rods 402, which can increase the moving speed of the lower mold base 202 and improve the forming efficiency of the double elbow rod force-enhancing aluminum-plastic aluminum-aluminum blister forming device in this embodiment.

[0037] In another embodiment provided in this application, please refer to Figures 1 to 4, one end of the two elbows 402 connected to the floating plate 401 is arranged along the relative direction of the upper mold base 201 and the lower mold base 202. According to the above structure provided in this embodiment, the two elbows 402 can be rotated to the same vertical direction, so that the force applied to the connecting rod 302 can be converted to the lower mold base 202 to the greatest extent, which is conducive to further improving the forming force of the double elbow force-enhancing aluminum-plastic aluminum-aluminum blister forming device in this embodiment.

[0038] In another embodiment provided in this application, please refer to Figures 1 to 4 , at least two groups of elbows 402 are arranged at intervals along the moving direction of the connecting rod 302. The force-increasing assembly also includes an upper connecting seat 403 connected to the lower mold base 202 and a base 404 connected to the bottom plate 102. Some of the elbows 402 used to connect with the lower mold base 202 are connected to the lower mold base 202 through the upper connecting seat 403, and some of the elbows 402 used to connect with the bottom plate 102 are connected to the bottom plate 102 through the base 404. According to the above structure provided in this embodiment, the floating plate 401 can be hinged to the lower mold base 202 through the multiple elbows 402 connected to the upper connecting seat 403 and connected to the bottom plate 102 through the multiple elbows 402 connected to the base 404, which is conducive to improving the moving stability of the lower mold base 202 and providing greater blister forming force.

[0039] In another embodiment provided in this application, please refer to Figures 1 to 4 Two connecting rods 302 are provided along the axial direction of the eccentric shaft 301 and are respectively hinged on opposite sides of the floating plate 401. According to the above structure provided in this embodiment, the two connecting rods 302 connected to the eccentric shaft 301 can provide a greater horizontal driving force for the floating plate 401 on the one hand, and can also improve the movement stability of the floating plate 401 in the horizontal direction on the other hand, thereby facilitating further improving the movement stability of the lower mold base 202 and providing a greater blister forming force.
