[0028] It should be noted that in the embodiment, the elastic force of the springs 41 can separate the formed product from the die body 36, facilitating the formed product to fall automatically when the die body 36 flips.

[0029] For the embodiments, please refer to Figure 2 , on one side of the hole body of the rectangular hole, there is a first T-shaped sliding groove 111;

[0030] On one side of the sliding rack 34, a first T-shaped slider 341 is fixed, and the first T-shaped slider 341 is slidably connected to the groove body of the first T-shaped sliding groove 111.

[0038] It should be noted that, in the embodiments, the limit plates 12 facilitate restricting the position of the mold body 36 and prevent the mold body 36 from rotating. The inclined edges facilitate increasing the space for the mold body 36 to enter between the limit plates 12.

[0039] The specific operation method of the present utility model is as follows:

[0040] The demolding mechanism of the above-mentioned thermoforming die drives the forming block 22 to descend through the air cylinder 21, thereby performing a forming operation on the product. When the forming block 22 ascends, the elastic force of the spring 41 can separate the formed product from the mold body 36. Then, the rotation motor 31 drives the first gear 33 to rotate, thereby driving the sliding rack 34 to ascend.
