[0023] When the upper mold 2 needs to be replaced, the connecting part 210 is disconnected from the fixing component 100, the movable component 200 can be removed from the fixing component 100, and then the upper mold 2 can be removed from the mounting part 220. When installing the upper mold 2, the replaced upper mold 2 is detachably installed on the mounting part 220, and then the connecting part 210 is connected to the fixing component 100. When disassembling and assembling the upper mold 2, workers no longer need to extend their upper body between the upper mold 2 and the lower mold, and use tools to disassemble and assemble the screws one by one, which saves time and effort.

[0024] As a preferred embodiment, please refer to Figure 1 The fixing assembly 100 includes two fixing blocks 120, which are arranged opposite to each other and at intervals, and can be detachably fixed on the lifting frame 1 of the machine. The fixing block 120 is provided with the card slot 110, and the card slot 110 extends along the length direction of the fixing block 120, so that the connecting portion 210 can be slidably clamped in the card slot 110, thereby realizing the clamping connection with the fixing block 120.

[0025] As a preferred embodiment, please refer to Figure 1 and Figure 2 The connecting portion 210 is a plate-shaped structure, and its two ends are respectively slidably connected to the two slots 110. When the two ends of the connecting portion 210 are respectively slidably engaged in the corresponding slots 110, the connecting portion 210 and the fixing block 120 can be connected. When the two ends of the connecting portion 210 are respectively moved out of the corresponding slots 110, the connecting portion 210 and the fixing block 120 can be separated.

[0026] As a preferred embodiment, please refer to Figure 1 and Figure 2 The mounting portion 220 includes a plurality of mounting rods 221, the upper end of each mounting rod 221 is fixed to a side surface of the connecting portion 210, and the lower end of each mounting rod 221 is detachably connected to the upper mold 2, so that the mounting rods 221 can be detachably connected to the upper mold 2.

[0027] As a preferred embodiment, please refer to Figure 1 and Figure 2 Both ends of the card slot 110 are opened so that the connecting portion 210 can be moved into the card slot 110 from the end of the card slot 110 or moved out from the end of the card slot 110 .

[0035] In order to better understand the present invention, the following Figure 1 - Figure 2 The working principle of the technical solution of the utility model is described in detail:

[0036] When the upper mold 2 needs to be replaced, the two ends of the connecting portion 210 are respectively moved out of the corresponding card slots 110 to separate the connecting portion 210 from the fixing block 120, and then the screws connecting the upper mold 2 and each of the mounting rods 221 are removed one by one using a tool, so that the upper mold 2 can be removed, and the replaced upper mold 2 is installed on the mounting rods 221 via screws, and then the two ends of the connecting portion 210 are respectively slidably clamped in the corresponding card slots 110, so that the connecting portion 210 and the fixing block 120 can be clamped. The two ends of the part 210 are respectively clamped in the corresponding slot 110, and the two limit blocks 230 are respectively abutted against and magnetically attracted to one end of the corresponding fixing block 120, so as to form a limit on one end of the connecting part 210, and prevent the entire positioning device and the upper mold 2 from moving up and down with the lifting frame 1 of the machine. The connecting part 210 is moved out from the other end of the slot 110. When disassembling the upper mold 2, the workers no longer need to stretch their upper body between the upper mold 2 and the lower mold, and use tools to disassemble and assemble the screws one by one, which is more time-saving and labor-saving.

[0037] The upper mold positioning device for processing a blister tray provided by the utility model has the following beneficial effects:

[0038] (1) When the two ends of the connecting portion 210 are respectively clamped in the corresponding clamping slots 110, the two limiting blocks 230 are respectively in contact with and magnetically attracted to one end of the corresponding fixing block 120, thereby limiting one end of the connecting portion 210 and preventing the connecting portion 210 from moving out of the other end of the clamping slot 110 when the entire positioning device and the upper mold 2 move up and down following the lifting frame 1 of the machine platform;

[0039] (2) When the two ends of the connecting portion 210 are respectively slidably engaged in the corresponding engaging slots 110, the connecting portion 210 and the fixing block 120 can be engaged with each other. When the two ends of the connecting portion 210 are respectively removed from the corresponding engaging slots 110, the connecting portion 210 and the fixing block 120 can be separated, which facilitates assembly and disassembly.

[0040] (3) Since different upper molds 2 have different sizes and structures, the positioning device is used to fix the fixed component 100 to the lifting frame 1 of the machine, and different upper molds 2 are installed on the movable component 200. When disassembling and assembling the upper mold 2, workers no longer need to stretch their upper body between the upper mold 2 and the lower mold, and use tools to disassemble and assemble the screws one by one, which saves time and effort.

[0041] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
