[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4As shown, this utility model provides a technical solution: a foldable plastic mold, including a fixed plate 1, a circular slot 2 inside the fixed plate 1, a rotating rod 3 rotatably connected inside the circular slot 2, a folding plate 4 fixedly connected to the outer surface of the rotating rod 3, a spring 5 fixedly connected to one side of the rotating rod 3, a locking block 6 fixedly connected to one end of the spring 5, a telescopic rod 7 fixedly connected to one side of the bottom of the folding plate 4, a connecting plate 8 fixedly connected to the bottom of the telescopic rod 7, an installation groove 9 at the bottom of the connecting plate 8, an installation slider 10 slidably connected inside the installation groove 9, an upper mold 11 fixedly connected to the bottom of the installation slider 10, and a fixing screw 12 threadedly connected inside the installation slider 10. The operator flips the folding plate 4, which causes the rotating rod 3 to rotate inside the fixed plate 1. As the rotating rod 3 rotates, the circular slot 2 limits the rotation of the rotating rod 3. When the rotating rod 3 rotates to a certain angle, the locking block 6 will be locked into the slot inside the circular slot 2 due to the tension of the spring 5, thus fixing the folding plate 4. Flipping the folding plate 4 in the opposite direction can fold it up and store it, thereby reducing the space occupied by the device. The mounting slider 10 is slid into the mounting groove 9, and the mounting groove 9 limits the mounting slider 10. When the mounting slider 10 is completely in contact with the mounting groove 9, the fixing screw 12 is rotated to fix the upper mold 11 to the bottom of the connecting plate 8, thereby completing the replacement and installation of the upper mold 11.

[0023] The circular slot 2 has a slot 13 inside, and the card block 6 fits into the slot 13. When the card block 6 is inserted into the slot 13, the slot 13 applies a limit to the surface of the card block 6.

[0024] A rectangular plate 14 is fixedly connected to one side of the folding plate 4. A servo motor 15 is fixedly connected to the top of the rectangular plate 14. A bidirectional screw 16 is fixedly connected to the output end of the servo motor 15. An adjusting slider is threadedly connected to the outer surface of the bidirectional screw 16. A first limiting plate 17 is fixedly connected to the bottom of the adjusting slider. A first fixing rod 18 is fixedly connected to the inside of the first limiting plate 17. A movable plate 19 is rotatably connected to the outer surface of the first fixing rod 18. A second fixing rod 20 is rotatably connected to the inner side wall of the movable plate 19. A second limiting plate 21 is fixedly connected to the outer surface of the second fixing rod 20. The rectangular plate 14 supports and fixes the servo motor 15. When the device is connected to an external power source, the servo motor 15 is started to run, which drives the bidirectional screw 16 to rotate. The rotation of the bidirectional screw 16 drives the first limiting plate 17 and the first fixing rod 18 to move. The movement of the first fixing rod 18 drives the movable plate 19 to rotate. The rotation of the movable plate 19 drives the second fixing rod 20 and the second limiting plate 21 to move, thereby driving the connecting plate 8 to press down and form the plastic part.

[0025] The top of the connecting plate 8 is provided with a connecting groove, and the second fixing rod 20 is connected to the connecting groove. The second fixing rod 20 is supported and fixed by the setting of the connecting groove.

[0026] A lower mold 22 is fixedly connected to one side bottom of the fixed plate 1. When the upper mold 11 is pressed down into the lower mold 22, the plastic part can be formed and the upper mold 11 and the lower mold 22 fit together.

[0027] A positioning rod 23 is fixedly connected to the bottom of the connecting plate 8, and a positioning hole 24 is opened on the top of the lower mold 22. The positioning rod 23 fits into the positioning hole 24. When the connecting plate 8 is pressed down, it will drive the positioning rod 23 to insert into the positioning hole 24. At the same time, the positioning hole 24 limits the positioning rod 23 to prevent the position of the connecting plate 8 from shifting.

[0028] In this invention, the working steps of the device are as follows:

[0029] First step: The operator flips the folding plate 4. The flipping of the folding plate 4 causes the rotating rod 3 to rotate inside the fixed plate 1. At the same time as the rotating rod 3 rotates, the circular slot 2 limits the rotating rod 3. When the rotating rod 3 rotates to a certain angle, the locking block 6 will be locked into the slot inside the circular slot 2 due to the tension of the spring 5, thus fixing the folding plate 4. Flipping the folding plate 4 in the opposite direction can fold it up and store it, thereby reducing the space occupied by the device. The mounting slider 10 is slid into the mounting groove 9. At the same time, the mounting groove 9 limits the mounting slider 10. When the mounting slider 10 is completely in contact with the mounting groove 9, the fixing screw 12 is rotated to fix the upper mold 11 to the bottom of the connecting plate 8, thereby completing the replacement and installation of the upper mold 11.

[0030] Second step: When the card block 6 is inserted into the card slot 13, the card slot 13 applies a limit to the surface of the card block 6, the rectangular plate 14 supports and fixes the servo motor 15, the device is connected to an external power supply to start the servo motor 15 to run, drive the bidirectional screw 16 to rotate, the bidirectional screw 16 rotates and drives the first limit plate 17 and the first fixed rod 18 to move, the first fixed rod 18 moves and drives the movable plate 19 to rotate, the movable plate 19 rotates and drives the second fixed rod 20 and the second limit plate 21 to move, thereby driving the connecting plate 8 to press down, so that the plastic part is formed, and the second fixed plate 1 rod 20 is supported and fixed by the setting of the connecting groove;

[0031] Third step: When the upper mold 11 is pressed down into the lower mold 22, the plastic part can be formed and the upper mold 11 and the lower mold 22 are in contact. When the connecting plate 8 is pressed down, it will drive the positioning rod 23 to be inserted into the positioning hole 24. At the same time, the positioning hole 24 limits the positioning rod 23 to prevent the position of the connecting plate 8 from shifting.
