A plurality of upper and lower mold positioning components 5 are provided on both the upper mold positioning plate 31 and the lower mold positioning plate 41. Each upper and lower mold positioning component 5 includes a magnet 51 and a magnet buckle 52. The magnet buckles 52 of the plurality of upper and lower mold positioning components 5 are respectively arranged on the upper mold positioning plate 31 and the lower mold positioning plate 41.

The magnetic poles of the magnets 51 on the upper mold positioning plate 31 are different from the magnetic poles of the magnets 51 on the lower mold positioning plate 41; when the upper mold 1 and the lower mold 2 are closed, the magnets 51 on the upper mold positioning plate 31 attract the magnets 51 on the lower mold positioning plate 41 so that the upper mold 1 and the lower mold 2 are accurately closed.

[0029] During the process of closing the upper mold 1 and the lower mold 2, the magnets 51 on the upper mold positioning plate 31 attract the magnets 51 on the lower mold positioning plate 41 so that the upper mold 1 and the lower mold 2 can be accurately closed. The closing accuracy of the upper mold 1 and the lower mold 2 is high, and the blister products are not prone to deformation and error, ensuring the quality of the blister products. The magnet buckle 52 firmly buckles the magnet 51 on the upper mold positioning plate 31 and the lower mold positioning plate 41, enabling the magnet 51 to work stably. At the same time, the upper mold positioning component 3 and the lower mold positioning component 4 are detachable. The upper mold positioning component 3 and the lower mold positioning component 4 are equivalent to general positioning accessories and can be applied to different blister molds.

[0031] In actual use, first connect the upper die positioning plate 31 to the upper die 1, and connect the lower die positioning plate 41 to the lower die 2. Then press a plurality of magnets 51 into the magnet accommodating grooves 53 of the upper die 1 and the magnet accommodating grooves 53 of the lower die 2 respectively via a plurality of magnet avoidance grooves 522. During the process of pressing the magnets 51 into the magnet accommodating grooves 53, the magnets 51 press against and deform a plurality of clamping strips 521, and the free ends of the deformed plurality of clamping strips 521 protrude into the magnet accommodating grooves 53, preventing the plurality of clamping strips 521 from affecting the clamping of the upper die 1 and the lower die 2. At the same time, the magnet accommodating grooves 53 are clamped into the annular clamping grooves 511 of the magnets 51, and the plurality of clamping strips 521 tightly lock the magnets 51 to the upper die 1 and the lower die 2.

[0032] As Figures 1 to 8 shown, in this embodiment, the upper die positioning plate 31 is convexly provided with a plurality of tooth-shaped positioning members 311, the lower die positioning plate 41 is provided with a plurality of tooth-shaped positioning member avoidance grooves 411, the plurality of tooth-shaped positioning member avoidance grooves 411 respectively penetrate through the lower die positioning plate 41, and the lower die 2 is recessed with a plurality of tooth-shaped positioning member accommodating grooves 21 for accommodating the tooth-shaped positioning members 311.

[0033] During the process of clamping the upper die 1 and the lower die 2, the plurality of tooth-shaped positioning members 311 respectively protrude into the tooth-shaped positioning member accommodating grooves 21 via the plurality of tooth-shaped positioning member avoidance grooves 411, thereby ensuring the clamping accuracy of the upper die 1 and the lower die 2.

[0036] In actual use, multiple locking screws 42 lock the lower die positioning plate 41 to the lower die 2, thereby fixing the position of the lower die positioning plate 41. At the same time, during the mold closing process of the upper die 1 and the lower die 2, the screw heads of the locking screws 42 protrude into the screw receiving grooves 11 through the screw avoidance grooves 312, thereby ensuring the mold closing accuracy of the upper die 1 and the lower die 2. The thermoformed products are not prone to deformation and error, and thus the quality of the thermoformed products is ensured.

[0037] As Figures 1 to 8 shown, in this embodiment, the lower die positioning plate 41 is provided with multiple positioning protrusions 43, and the upper die positioning plate 31 is provided with multiple protrusion avoidance grooves 313 for avoiding the positioning protrusions 43. The multiple protrusion avoidance grooves 313 respectively penetrate through the upper die positioning plate 31; the upper die 1 is recessed with multiple protrusion receiving grooves 12 for receiving the positioning protrusions 43.

[0038] During the mold closing process of the upper die 1 and the lower die 2, the multiple positioning protrusions 43 respectively protrude into the protrusion receiving grooves 12 through the multiple protrusion avoidance grooves 313, thereby ensuring the mold closing accuracy of the upper die 1 and the lower die 2. The thermoformed products are not prone to deformation and error, and thus the quality of the thermoformed products is ensured.

[0039] As Figures 1 to 8 shown, in this embodiment, both the upper die positioning plate 31 and the lower die positioning plate 41 include two short sides 32 of the positioning plate and three long sides 33 of the positioning plate.

[0040] In actual use, multiple locking screws 42 lock the lower die positioning plate 41 to the lower die 2, thereby fixing the position of the lower die positioning plate 41. The upper die positioning plate 31 is buckled to the upper die 1 through the buckle bending portions 321, thereby fixing the position of the upper die 1. Then, the upper die positioning plate 31 and the lower die positioning plate 41 are respectively welded to the upper die 1 and the lower die 2 in the order from the middle to the outside, so that the upper die positioning plate 31 and the lower die positioning plate 41 are further fixed to the upper die 1 and the lower die 2, enabling the upper die positioning plate 31 and the lower die positioning plate 41 to work stably.
