Detailed Implementation

[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. Example

[0022] Please see Figure 1-4 This embodiment provides the following technical solution: a forming mold for producing disposable aluminum foil lunch boxes, including an upper stamping mold and a lower stamping mold disposed below the upper stamping mold. The upper stamping mold includes an upper template 1, a concave mold body 2 disposed below the upper template 1, a concave mold cover plate 3 disposed above the concave mold body 2, a feeding cylinder 4 disposed between the concave mold cover plate 3 and the upper template 1, the piston rod of the feeding cylinder 4 extending into the concave mold body 2 and fixedly connected to a feeding plate 5, and the feeding plate 5 being slidably connected to a feeding groove disposed at the top of the concave mold body 2.

[0023] In some embodiments, the feeding cylinder 4 and feeding plate 5 can smoothly push the aluminum foil lunch box out of the concave mold body 2, avoiding the problem of deformation of the aluminum foil lunch box when it is pushed out of the concave mold body 2 due to the deviation of the pushing direction, thereby improving the production effect of the aluminum foil lunch box.

[0024] It also includes a mounting template 6, which is fixedly installed on the stamping equipment. The upper stamping die is fixedly connected to the mounting template 6, and the upper stamping die and the lower stamping die are movably connected by several sets of guide rod mechanisms 7.

[0025] In some embodiments, the upper stamping die moves along the direction of the guide rod mechanism 7, so that the upper stamping die and the lower stamping die cooperate to stamp the aluminum foil.

[0026] The stamping die includes a lower die plate 8, and a convex die body 9 adapted to the concave die body 2 is provided above the lower die plate 8. The concave die body 2 and the convex die body 9 work together to form the stamping structure of the aluminum foil lunch box. In some embodiments, there are multiple concave die bodies 2 and convex die bodies 9. By setting a batch of concave die bodies 2 and convex die bodies 9, aluminum foil lunch boxes can be stamped in batches, which improves the production efficiency of aluminum foil lunch boxes.

[0027] A positioning sleeve 10 is fixedly connected to the piston rod of the feeding cylinder 4. The positioning sleeve 10 is provided with a first screw hole. The first screw hole is adapted to the first screw 11 that passes through the feeding plate 5. The other end of the first screw 11 is inserted into the first screw hole and threadedly connected to the first screw hole. Through the positioning sleeve 10 and the first screw 11, the feeding plate 5 can be quickly installed and removed from the feeding cylinder 4, so that the feeding plate 5 on the concave mold body 2 can be quickly replaced according to the different types of aluminum foil lunch boxes.

[0028] The bottom of the positioning sleeve 10 is fixedly connected to a positioning post 12. The positioning post 12 is movably inserted into the positioning groove 13 provided on the ejector plate 5. Through the positioning post 12 and the positioning groove 13, when the die cover plate 3 is closed on the die body 2, the positioning post 12 on the positioning sleeve 10 is inserted into the positioning groove 13 on the ejector plate 5, which increases the horizontal limiting effect of the ejector plate 5, thereby increasing the stability of the positioning sleeve 10 on the ejector cylinder 4, and further improving the stability of the vertical reciprocating motion of the ejector plate 5 driven by the positioning sleeve 10.

[0029] A limiting component 14 is provided above the die body 2 to limit the ejector plate 5. In some embodiments, several limiting components 14 are provided, and the array of several limiting components 14 is distributed above the die body 2. The limiting component 14 includes a sliding sleeve 141 and a second screw 142. The sliding sleeve 141 is movably inserted into the sliding groove provided on the die body 2. The second screw 142 is movably inserted through the sliding sleeve 141 and is detachably connected to the second screw hole provided on the ejector plate 5. By the sliding sleeve 141 sleeved on the outside of the second screw 142, while the second screw 142 is fixed on the ejector plate 5, the threads on the second screw 142 are prevented from engaging with the sliding groove, which increases the smoothness and stability of the sliding sleeve 141 when moving in the sliding groove, thereby further improving the stability of the ejector plate 5 when sliding vertically.

[0030] A limiting sleeve 143 is also fixedly connected to the outer side of the top of the sliding sleeve 141. The limiting sleeve 143 can limit the vertical downward movement distance of the sliding sleeve 141 and play a buffering effect when the top of the second screw 142 contacts the die cover plate 3.

[0031] 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.
