Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1-3A foldable and portable mold includes an upper mold 1, a base 3 at the bottom of the upper mold 1, and bases 14 slidably connected inside both the upper mold 1 and the lower mold 2. Side plates 4 are fixedly installed on opposite sides of the upper mold 1, and a rotating shaft 6 is fixedly installed between the two side plates 4. The rotating shaft 6 is inserted into the interior of the two side plates 4 and rotatably connected thereto. The lower mold 2 is fixedly installed on the outside of the rotating shaft 6. Insert plates 5 are provided on the top of both side plates 4. The insert plates 5 are inserted into the interior of the side plates 4 and slidably connected thereto. Several tension springs 7 are fixedly installed at the bottom of both insert plates 5. The ends of the tension springs 7 away from the insert plates 5 are fixedly connected to the side plates 4. Several grooves that mate with the insert plates 5 are provided on the top of the side plates 4.

[0026] Two insert rods 8 are fixedly installed at the bottom of each of the two insert plates 5. Several insert rods 8 are inserted into the inside of the rotating shaft 6 and slidably connected to it. Two mutually cooperating buckles 19 are fixedly installed on one side of the upper mold 1 and the lower mold 2.

[0027] T-shaped rotating rods 15 are provided on the opposite sides of the two bases 14. The T-shaped rotating rods 15 are inserted into the bases 14 and rotatably connected to them. The two T-shaped rotating rods 15 are respectively inserted into the upper mold 1 and the lower mold 2 and rotatably connected to them. T-shaped rotating cylinders 16, second worm gears 17 and second worms 18 are rotatably connected to the interiors of the upper mold 1 and the lower mold 2. T-shaped rotating cylinders 16 are inserted into the T-shaped rotating rods 15 and threadedly connected to them. T-shaped rotating cylinders 16 are fixedly connected to the second worm gears 17. The second worm gears 17 mesh with the second worms 18. A first rotating handle is fixedly installed on one side of each of the two second worms 18. The first rotating handle passes through one side of the upper mold 1 and the lower mold 2 and is rotatably connected to them. Rubber pads are fixedly installed at the bottom of several threaded rods 13. A feed port is provided on the lower mold 2. Sealing rings are provided on the side of each base 14 near the upper mold 1 and the lower mold 2.

[0028] By pulling the two insert plates 5, the restriction on the rotating shaft 6 is released, which facilitates the unfixation of the upper mold 1 and the lower mold 2. This further facilitates the replacement and connection of the upper mold 1 and the lower mold 2 according to the needs of the mold, improving the applicability of the device. At the same time, after the upper mold 1 and the lower mold 2 are connected, the lower mold 2 is rotated to contact the top of the upper mold 1, achieving precise positioning of the upper mold 1 and the lower mold 2. With the cooperation of the set buckle 19, the upper mold 1 and the lower mold 2 are combined and connected, improving the stability when using the mold.

[0029] By rotating the first levers on the upper mold 1 and the lower mold 2, the second worm gear 18 meshes with the second worm wheel 17, causing the T-shaped rotating rod 15 on the outside of the T-shaped rotating cylinder 16 to move longitudinally, thereby adjusting the distance between the base 14 and the upper mold 1 or the lower mold 2, which is convenient for adjustment according to the needs of the mold.

[0030] Please see Figure 4 The base 3 is provided with several adjustment structures, including a first worm gear 10, a first worm 11, a connecting cylinder 12, and a threaded rod 13. The first worm gear 10, the first worm 11, the connecting cylinder 12, and the threaded rod 13 are all rotatably connected to the base 3. The first worm gear 10 and the first worm 11 are meshed. The first worm gear 10 is fixedly connected to the connecting cylinder 12. The threaded rod 13 is inserted into the interior of the connecting cylinder 12 and threadedly connected to it. The threaded rod 13 passes through the bottom of the base 3 and is rotatably connected to it. A second lever is fixedly installed on one side of the first worm 11, and the second lever passes through one side of the base 3 and is rotatably connected to it.

[0031] The bottom of the base 3 is provided with several fixing bolts 9, which all pass through the base 3 and are threaded to it. The fixing bolts 9 are also inserted into the interior of the upper mold 1 and are threaded to it.

[0032] The upper mold 1 and the base 3 are connected by the fixed bolts 9. By rotating the second lever, the first worm wheel 10 on one side of the first worm 11 is rotated, causing the threaded rod 13 at the bottom of the connecting cylinder 12 to move longitudinally. The threaded rod 13 moves out of the interior of the base 3 and contacts the operating table surface, making the device easy to adapt to uneven operating table surfaces. At the same time, when the threaded rod 13 moves up into the interior of the base 3, the rubber pad at the bottom of the threaded rod 13 is at the same level as the bottom of the base 3, thereby increasing the friction between the threaded rod 13 and the operating table surface.

[0033] Working principle: The upper mold 1 and the base 3 are connected by the fixed bolts 9. By rotating the second lever, the first worm wheel 10 on one side of the first worm 11 is rotated, causing the threaded rod 13 at the bottom of the connecting cylinder 12 to move longitudinally. The threaded rod 13 moves out of the base 3, so that the base 3 is placed horizontally on the operating table. The appropriate upper mold 1 and lower mold 2 are selected and connected. By pulling the two insert plates 5, the rotating shaft 6 is inserted into it. The insert plates 5 are reset by the tension spring 7, and the insert rod 8 is inserted into the rotating shaft 6 to limit its movement. The upper mold 1 and lower mold 2 are rotated to fit together, and the combination connection of the upper mold 1 and lower mold 2 is achieved by the engagement of the buckle 19. At the same time, by rotating the first lever on the upper mold 1 and lower mold 2, the second worm 18 and the second worm wheel 17 are engaged, causing the T-shaped rotating rod 15 on the outside of the T-shaped rotating cylinder 16 to move longitudinally, thereby adjusting the mold space in the upper mold 1 or lower mold 2.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
