[0024] 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.

[0025] Example

[0026] Please see Figure 1-5 This embodiment provides the following technical solution: a one-time forming aluminum foil lunch box forming mold, including an upper mold plate 1 and a lower mold plate 2, which are movably connected by a guide mechanism 3. A concave mold 4 is fixedly connected to the upper mold plate 1, and a convex mold 5 is fixedly connected to the lower mold plate 2. The convex mold 5 and the concave mold 4 cooperate to form the forming structure of the aluminum foil lunch box. Under the drive of the stamping equipment, the upper mold plate 1 moves closer to or further away from the lower mold plate 2 along the guide mechanism 3, so that the convex mold 5 and the concave mold 4 cooperate to perform stamping forming operation on the aluminum foil lunch box.

[0027] The punch mold 5 includes a mold frame 51, a textured plate 52, and a cooling platform. The top of the mold frame 51 is provided with a first mounting cavity 53 for mounting the textured plate 52, and the bottom of the mold frame 51 is provided with a second mounting cavity 54 for mounting the cooling platform. The side wall of the cooling platform is provided with a cooling groove 55 for supplying coolant to cool the mold frame 51. Through the cooling groove 55, the coolant circulates in the punch mold 5. While the coolant is circulating, it can carry away the heat on the punch mold 5, achieving the effect of rapid cooling of the aluminum foil lunch box. This not only improves the quality and production efficiency of the aluminum foil lunch box, but also increases its production efficiency and service life.

[0028] A ventilation cavity 56 is provided inside the mold frame 51 to connect the first mounting cavity 53 and the second mounting cavity 54. A number of distributed first cooling holes 57 are provided on the textured plate 52, which are connected to the ventilation cavity 56. A second cooling hole 58 is provided on the cooling platform, which is connected to the ventilation cavity 56. Through the ventilation cavity 56, the first cooling hole 57 and the second cooling hole 58, after the convex mold 5 and the concave mold 4 are closed, the air in the mold cavity can circulate with the outside air, achieving the effect of natural ventilation for the aluminum foil lunch box.

[0029] The bottom of the cooling tank 55 is provided with an inlet pipe 511 and a drain pipe 512. The other ends of the inlet pipe 511 and the drain pipe 512 extend to the outside of the cooling platform. In some embodiments, the inlet end of the inlet pipe 511 is connected to a liquid injection device, which allows the coolant to enter the cooling tank 55. The drain end of the drain pipe 512 is connected to a circulating cooling device, which can discharge the coolant that has absorbed excessive temperature from the cooling tank 55, and can also cool the coolant and reuse it.

[0030] The cooling platform includes a boss 59 and an outer plate 510. The boss 59 is movably inserted into the mold frame 51. The bottom of the boss 59 is fixedly connected to the outer plate 510 located on the outside of the mold frame 51. Through the boss 59 and the outer plate 510, the cooling platform can better seal the second mounting cavity 54 and prevent coolant from seeping out of the cooling tank 55.

[0031] The outer plate 510 is provided with a first positioning hole, and a bolt 513 is movably connected in the first positioning hole. The other end of the bolt 513 passes through the boss 59 and is threadedly connected to the second positioning hole on the mold frame 51. The bolt 513 facilitates the installation and removal of the cooling platform on the mold frame 51.

[0032] Sealing rings are fixedly connected to the side wall at the top and bottom of the boss 59. The sealing rings further enhance the sealing between the cooling platform and the inner wall of the second mounting cavity 54, allowing the coolant to circulate better in the cooling tank 55.

[0033] The working principle of this utility model is as follows: When in use, after the aluminum foil sheet is placed on the convex mold 5, the stamping equipment is started, so that the upper mold plate 1 drives the concave mold 4 to move down along the guide mechanism 3, so that the concave mold 4 and the convex mold 5 cooperate to complete the stamping operation of the aluminum foil lunch box.

[0034] During the forming process of the aluminum foil lunch box, the cooperation of the first cooling hole 57, the connecting cavity and the second cooling hole 58 can achieve the effect of natural ventilation for the aluminum foil lunch box.

[0035] At the same time, the liquid injection equipment is started, so that the coolant enters the cooling tank 55 through the liquid inlet pipe 511. The coolant will circulate in the cooling tank 55. The circulating cooling equipment is started, so that the coolant in the cooling tank 55 is discharged from the cooling chamber through the liquid outlet pipe 512. During the process of the coolant being discharged, the coolant can carry away the heat on the mold frame 51 and the textured plate 52, thereby achieving the cooling effect on the aluminum foil lunch box.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
