[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0025] Reference Figure 1-4 A molding die comprises an upper die 2 and a lower die 1, wherein three protrusions 7 are fixedly provided at the bottom of the upper die 2, and three molding grooves 4 corresponding to the protrusions 7 are opened at the top of the lower die 1. Such a design enables the protrusions 7 to be accurately inserted into the molding grooves 4 when the mold is closed, thereby forming a specific shape of the head.

[0026] It is worth noting that the lower mold 1 is a hollow structure with an opening on one side. This design allows the space inside the mold to be utilized, and the opening facilitates the installation and maintenance of the internal parts of the mold. In addition, a disassembly plate 3 is provided on one side of the lower mold 1 and fixed by bolts, so that one side of the lower mold 1 can be easily disassembled when it is necessary to clean or replace internal parts.

[0027] In order to lift the formed head, the mold is also provided with a lifting mechanism, which includes four electric push rods 9 and a movable plate 8. The fixed parts of the four electric push rods 9 are respectively fixedly connected to the four corners of the bottom inner wall of the lower mold 1, and the two sides of the movable plate 8 are slidingly connected to the inner walls of the two sides of the lower mold 1. The telescopic parts of the electric push rods 9 are respectively fixedly connected to the four corners of the bottom of the movable plate 8. When the electric push rods 9 are telescopic, they will drive the movable plate 8 to move up and down in the lower mold 1.

[0028] Two through holes are provided on the inner walls of the three molding grooves 4, and a lifting plate 6 is slidably connected in the through holes. The bottoms of the six lifting plates 6 are connected to the movable plate 8. Therefore, when the movable plate 8 moves upward, the lifting plate 6 will also move upward, thereby lifting the molded head from the molding groove 4 to facilitate demolding.

[0029] The present application is used in the field of large-scale head flap forming, and can also be used in other fields applicable to the present application. Example

[0030] refer to Figure 1-4 , based on the improvement of the first embodiment: a head forming mold, which is used in the field of forming molds,

[0031] In order to facilitate the installation and fixation of the mold, mounting plates 5 are fixedly arranged on both sides of the upper mold 2 and the lower mold 1. The mounting plates 5 are provided with mounting holes, and the mold can be fixed in a suitable position by bolts or other fasteners. In order to enhance the stability and durability of the mold, support plates 10 are fixedly arranged on the inner walls of both sides of the lower mold 1, and the moving plate 8 is located above the two support plates 10. Such a design can ensure that the moving plate 8 always remains stable during the movement process and is not prone to shaking or deformation.

[0032] At the same time, in order to reduce the friction generated by the movable plate 8 when it moves, slide grooves 11 are also opened on the inner walls of both sides of the lower mold 1, and sliders are fixedly set on both sides of the movable plate 8. One side of the slider is slidably connected to the inner wall of the slide groove 11, so that the movable plate 8 moves up and down more smoothly, reducing unnecessary wear and resistance.

[0033] However, as is well known to those skilled in the art, the working principle and wiring method of the electric push rod 9 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
