[0025] Reference Figures 1-6 During the heating and forming process of the vacuum forming machine, both the product and the vacuum forming film need to be positioned. If displacement occurs during operation, it will affect the overall vacuum forming effect. The first hydraulic rod 203, the connecting strip 202, and the operating table 3 are connected by bolts. The connecting strip 202 and the pressure ring 201 are connected by bolts. The lower pressure block 4 and the insertion groove 204 are connected by insertion. The pressure ring 201 and the lower pressure block 4 form a clamping structure between the upper and lower ends of the vacuum forming film. The machine box 1, the lower pressure block 4, and the second hydraulic rod 401 are connected by bolts. In use, the vacuum forming film can be placed between the pressure ring 201 and the lower pressure block 4. Then, the second hydraulic rod 401 drives the lower pressure block 4 to press down and initially press the edge of the vacuum forming film. Then, the first hydraulic rod 203 drives the pressure ring 201 to rise, forming a secondary pressing. The pressure ring 201 is partially pressed into the lower end of the lower pressure block 4, making the edge of the vacuum forming film more stable. This ensures the positioning of the edge of the vacuum forming film and effectively improves the stability of the edge of the vacuum forming film during vacuum forming.
