[0023] A motor 102 is installed on one side of the shell 101, and a rotating rod 103 is installed on the output end of the motor 102 through a coupling. One end of the rotating rod 103 is connected to the linkage wheel 202 through a coupling.

[0027] The rotating rod 103 is connected to the linkage wheel 202 through a coupling, and the side plate 205 is connected to the first connecting plate 201 through a rotating shaft. Because the side plate 205 is connected to the first connecting plate 201 through a rotating shaft, and the rotating block 206 is fixedly connected to the side plate 205, the first connecting plate 201 will not drive the rotating block 206 to rotate.

[0029] The inner wall of the plastic film forming pressing block 406 is adapted to the workbench 302 , and a cavity is provided on one side of the outer wall of the plastic film forming pressing block 406 , and the cavity of the plastic film forming pressing block 406 is connected to the connecting block 403 .

[0030] Two top brackets 104 are provided, a fan 401 is installed on the top of the outer wall of one top bracket 104, and a cylinder 404 is installed on the bottom of the outer wall of the other top bracket 104.

[0031] The working principle and use process of the present invention are as follows: First, when using the mold of the present invention, it needs to be installed on the outer wall of the workbench 302. When the user needs to replace the mold, he only needs to start the motor 102. After the motor 102 is started, it will drive the rotating rod 103 to rotate. When the rotating rod 103 rotates, it will drive the interlocking wheel 202 to rotate. Since the inner wall of the first connecting plate 201 is provided with tooth grooves, when the interlocking wheel 202 rotates, it will drive the first connecting plate 201 to rotate. Because the side plate 205 is connected to the first connecting plate 201 through a rotating shaft, and the rotating block 206 is fixedly connected to the side plate 205, the first connecting plate 201 will not drive the rotating block 206 to rotate. When the first connecting plate 201 rotates, it will drive the connecting rod 203 to rotate. When the connecting rod 203 rotates, it will drive the second connecting plate 204 to rotate. When the connecting rod 203 rotates, it will also drive the connecting block 301 When the connecting block 301 rotates, the rotating wheel 306 movably installed at one end of the bottom chassis 305 thereof will rotate along the outer wall of the internal rotating block 206, and when the connecting block 301 rotates to the top of the internal rotating block 206, it will be lifted up by the protrusion 207, and at this time, the slide groove provided on the outer wall of the connecting block 301 will slide upward along the slide rail 211, and the docking grooves 307 provided on both sides of the bottom of the outer wall of the connecting block 301 will also drive the first telescopic rod 209 and the spring 210 to stretch, and the synchronous rotating wheel 306 will also be stuck in the groove of the protrusion 207, and at this time, the connecting block 301 will drive the workbench 302 to push upward, so that the mold on the outer wall of the workbench 302 is lifted up from the inside of the shell 101 to the top of the shell 101, and the user can install molds of different shapes on each workbench, and when switching molds, it is only necessary to start the motor 102 to drive the workbench 302 to rotate to switch; Finally, when the rest of the workbenches 302 are not at the top, the first telescopic rod 209 and the spring 210 can connect the workbenches 302 with the fixing frame 208, so as to prevent the rest of the workbenches 302 from falling off. When the workbenches 302 are pushed up to the top of the shell 101, the vacuum forming operation steps can be started. The user only needs to start the cylinder 404. After the cylinder 404 is started, it will drive the connecting frame 405 to move. When the connecting frame 405 moves, it will drive the plastic film forming pressing block 406 to move. When the plastic film forming pressing block 406 moves, it will move up and down. When the plastic film forming pressing block 406 moves to the outer wall of the workbench 302, it will cover the workbench 302, and the plastic film forming pressing block 406 will move to the outer wall of the workbench 302. The film is installed on the inner wall of the plastic film-forming pressing block 406. At this time, the plastic film will cover the mold. Since the cavity of the plastic film-forming pressing block 406 is connected to the connecting block 403, the user will start the fan 401 to suck out the air inside the plastic film-forming pressing block 406 through the air pipe 402 and the connecting block 403. The air will enter the air outlet cavity 304 through the suction cavity 303, and then be guided to the cavity of the plastic film-forming pressing block 406. After that, the plastic can be formed, and the heating plate 105 can heat and soften the plastic film on the inner wall of the plastic film-forming pressing block 406 for subsequent operations. After the plastic is formed, the user can take out the plastic inside the plastic film-forming pressing block 406. At this point, the work of the present invention is completed.

[0032] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
