The mold 4 provides a template for the product shape, and the heated plastic film is adhered to the mold surface by negative pressure adsorption to form the shape of the final product. A vacuum pump 5 is set in the lower part of the bracket 1, and the extraction end of the vacuum pump 5 is connected to the bottom of the mold 4. The vacuum pump 5: extracts air through the vents on the mold 4 to create a negative pressure environment so that the softened plastic film is close to the surface of the mold 4. Electric push rods Ⅰ6 are set on both sides of the lower part of the bracket 1. Electric push rods Ⅰ6: are used to adjust the position of the adapter 7, and then control the up and down movement of the mold 4 and the cover plate 11 to realize heating, molding and other processes. The telescopic ends of the side electric push rods Ⅰ6 are each provided with an adapter frame 7. The adapter frame 7 is used in conjunction with the electric push rod Ⅰ6 to slide on the guide rail 8 to adjust the position of the mold 4 to adapt to products of different sizes. Guide rails 8 are provided on both sides of the middle of the bracket 1. Guide rails 8 provide linear guidance for the adapter frame 7 to ensure the precise positioning of the mold 4. The middle parts of the adapter frames 7 on both sides are slidably connected to the adjacent guide rails 8, and an assembly frame 9 is commonly provided between the sides of the adapter frames 7 that are close to each other. The assembly frame 9 is in sliding contact with the mold 4. Electric push rods Ⅱ10 are provided on both sides of the assembly frame 9. A cover plate 11 is provided between the telescopic ends of the electric push rods Ⅱ10 on both sides. The bottom of the cover plate 11 fits tightly with the top of the assembly frame 9. Both the plate 11 and the front side of the assembly frame 9 are provided with empty slots, and the empty slots of the two are connected to form a matching clamping port. The cover plate 11 and the assembly frame 9 together form a closed space to facilitate molding operations, and are provided with a clamping port for separating the molded products. A winding wheel 12 is provided on the rear side of the assembly frame 9 for storing and unfolding the plastic film to be processed, providing raw materials for the molding process. An electric slide rail Ⅰ13 is provided on the crossbeam on the front side of the middle part of the bracket 1 for controlling the position of the film cutting knife 14 to ensure the accuracy of the cutting action.

A mold removal part for clamping the molding template is provided on the front side of the middle part of the bracket 1.

[0023] like Figure 1 、 Figure 6 and Figure 7As shown, the mold removal part includes an electric slide rail II 131, a rodless cylinder 16, a guide block 17, an electric cylinder 18, a wedge frame, a clamping claw 20, an articulated frame 21 and a spring 22. The two folding rods of the bracket 1 are provided with electric slide rails II 131 to provide the mold removal part with horizontal movement capability. The slide seats 15 of the two electric slide rails II 131 are provided with rodless cylinders 16 to provide the mold removal part with vertical movement capability. The rodless cylinders 16 are slidably provided with guide blocks 17, and the guide blocks 17 are provided with electric cylinders 18. The electric cylinders 18 drive the clamping claws 20 to open and close to realize the grasping of the product. The piston rod of the electric cylinder 18 is provided with a guide block 17. A tripod 19 is provided, and an articulated frame 21 is provided on both sides of the electric cylinder 18. The articulated frame 21 is located between the middle parts of the clamping jaws 20 on both sides. The clamping jaws 20 are hinged on both sides of the articulated frame 21.

A spring 22 is provided on one side of the middle part of the clamping jaws 20 on both sides close to the articulated frame 21 to provide a reset force so that the clamping jaws 20 remain in a closed state when there is no external force. When the electric cylinder 18 drives its piston rod to extend, the tripod 19 moves synchronously and drives the clamping jaws 20 on both sides to slide and cooperate and be in an open state, so that the spring 22 stretches and deforms, and after the spring 22 is reset, the clamping jaws 20 are tightly closed.

[0024] First, the plastic film roll is placed on the winding wheel 12, and then it is pulled out, and at the same time, the electric push rod II 10 is started to drive the cover plate 11 to rise, and then fall, so that the adapter 7 and the cover plate 11 are fitted together. At this time, the electric push rod I6 is started to drive the two to rise linearly along the guide rail 8, and heat them through the heating cover 3. The heating element built into the heating cover 3 evenly distributes heat, so that the plastic film reaches the softening point and enters the plastic state, preparing for the next step of forming; once the plastic film reaches the appropriate softening degree, the electric push rod I6 is driven to drive the two to fall, and the adapter 7 is closed on the mold 4, and the plastic film is also synchronously lowered to cover the surface of the mold 4. At this time, the vacuum pump 5 starts to work, and air is extracted from the pre-designed vents at the bottom of the mold 4 to generate sufficient negative pressure so that the softened plastic film is tightly adsorbed on the mold. The surface of the mold 4 is formed into the required three-dimensional shape; then, it undergoes natural cooling or external forced air cooling; when the product is completely cooled and shaped, the electric push rod I6 starts, driving the adapter frame 7 to move smoothly along the guide rail 8, and the assembly frame 9 also moves accordingly, until the cover plate 11 is accurately docked with the top of the mold 4; the electric push rod II 10 pushes the cover plate 11 downward, and after the cover plate 11 is tightly fitted with the mold 4, the clamping port automatically opens, thereby separating the formed product from the mold 4; then, the film cutting knife 14 moves along the electric slide rail I 13, accurately cutting off the excess part to make the edge of the finished product neater. After cutting, the finished product falls into the collection box 2 below; finally, the rodless cylinder 16 in the mold removal part drives the guide block 17 to move, and the electric cylinder 18 controls the opening and closing of the clamping jaws 20 to realize automatic grabbing of the finished product and move it to the designated location for storage.
