The positioning groove 4 is opened on the upper end face of the fixed base 3, and the limit block 5 is slidably arranged inside the positioning groove 4. The forming mold 6 is arranged above the fixed base 3, and the heat sealing strip 7 is provided on the upper end face of the forming mold 6. Several sets of air holes 8 are opened on the upper end face of the forming mold 6, and the first diversion pipe 9 is arranged inside the forming mold 6. This design solves the problem that the replacement of the original hot press forming mold for gourd film production is inconvenient.

[0022] As the first embodiment of this utility model: Both ends of the molding mold 6 are provided with wiring plates 71. A heating wire is embedded inside the heat-sealing strip 7, and both ends of the heating wire are electrically connected to the wiring plates 71 via wires. The wiring plates 71 are used to supply power to the heat-sealing strip 7. The outer surface of the heat-sealing strip 7 is provided with a nano-level ceramic coating. This design can reduce the friction coefficient of the heat-sealing strip 7 surface, thereby improving the smoothness of demolding. A conductive base 31 is provided on the upper end face of the fixed base 3, and a conductive plug 72 is provided on the lower end face of the molding mold 6. The conductive base 31 and the conductive plug 72 are matched. When the plugs 72 are plugged in, they can supply power to the heat-sealing strip 7. An air inlet 91 is located in the center of the first branch pipe 9. An air pump nozzle 32 is located on the upper surface of the fixed base 3. The air pump nozzle 32 engages with the air inlet 91, allowing the air pump nozzle 32 to inflate the first branch pipe 9 through the air inlet 91. A second branch pipe 92 is located inside the molding mold 6. Several sets of second branch pipes 92 are arranged according to their specifications. The first branch pipe 9 is connected to several sets of second branch pipes 92, and the second branch pipes 92 are connected to several sets of air holes 8. The first branch pipe 9 can supply power to the second branch pipe 9. 2. Inflation is performed. The second diversion pipe 92 can discharge air from several sets of air holes 8, thereby enabling demolding. The lower end face of the molding mold 6 is provided with positioning blocks 61. Four sets of positioning blocks 61 are provided, and the four sets of positioning blocks 61 are located at the four corners of the lower end face of the molding mold 6. The positioning blocks 61 and positioning grooves 4 engage with each other. The positioning blocks 61 and positioning grooves 4 can be used for positioning when installing the molding mold 6. The outer side of the positioning block 61 is provided with a limiting groove 62. The limiting groove 62 engages with a limiting block 5. The limiting block 5 and limiting groove 62 can limit and fix the positioning block 61. The base 3 has a sliding groove 41 inside, which is connected to the positioning groove 4. The limiting block 5 slides tightly along the inner wall of the sliding groove 41. The outer side of the fixed base 3 is provided with a handle 52. The end of the limiting block 5 that is relatively away from the positioning groove 4 is provided with a connecting rod 51. The limiting block 5 is connected to the handle 52 through the connecting rod 51. The outer side of the connecting rod 51 is provided with a return spring 53. The two ends of the return spring 53 abut against the limiting block 5 and the inner wall of the sliding groove 41, respectively. The handle 52 and the connecting rod 51 facilitate pulling the limiting block 5, and the return spring 53 helps the limiting block 5 to reset.

[0023] As a second embodiment of this utility model: The user places the double-layer plastic film on the upper surface of the molding mold 6, then operates the control panel 2 to control the pressure plate on the upper surface of the hot press body 1 to move downwards and cooperate with the molding mold 6 to press the plastic film. Then, the user controls the heating wire embedded in the heat sealing strip 7 to turn on and heat the heat sealing strip 7. The heat sealing strip 7 melts and adheres the corresponding positions of the double-layer plastic film, forming a gourd shape between the heat sealing strips 7. After hot pressing, the pressure plate rises, and the air pump nozzle 32 inflates the first diversion pipe 9 through the air inlet 91. The first diversion pipe 9 sprays air through the second diversion pipe 92 into several air holes 8, thereby separating the plastic film from the surface of the molding mold 6, reducing the mechanical contact damage caused by traditional demolding methods. Depending on the application scenario, the required size of the gourd-shaped air bubbles varies. When it is necessary to replace the molding mold 6 with a different specification, the user pulls the handle 52 outward. The handle 52 drives the limiting block 5 to slide along the inner wall of the sliding groove 41 through the connecting rod 51. While compressing the reset spring 53, the mutual engagement between the limiting block 5 and the limiting groove 62 is released, so that the positioning block 61 is no longer limited. Then, the molding mold 6 is lifted upward, so that the conductive plug 72 is disengaged from the conductive base 31 and the air pump nozzle 32 is disengaged from the air inlet 91, thus completing the disassembly. The same applies to the installation. The positioning block 61 is aligned with the positioning groove 4 and inserted. Then, the limiting block 5 is engaged with the limiting groove 62 to fix the position of the positioning block 61. At the same time, the conductive plug 72 is inserted into the conductive base 31 and the air pump nozzle 32 is inserted into the air inlet 91.
