[0015] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 4 It can be seen that a stamping die for producing aluminum foil lunch boxes includes a lower die 1 and an upper die 2 that cooperate with each other, the lower die 1 is provided with a plurality of die cavities 3, the upper die 2 is correspondingly provided with a plurality of punches 4, a top plate 5 is telescopically provided at the bottom of the die cavity 3, the plurality of top plates 5 are connected to a connecting plate 6 located inside the lower die 1, the connecting plate 6 is controlled to rise and fall by a first hydraulic cylinder 7, a chamber 8 connected to an air compressor is provided in the upper die 2, an outlet 9 connected to the chamber 8 is opened on the punch 4, and a stop rod 10 cooperating with the outlet 9 is telescopically provided in the punch 4.

[0017] When the utility model is used in a specific way,

[0018] Fix the mold on the punching machine, feed the aluminum foil into the punching position, start the punching machine to punch and form it, and the formed aluminum foil lunch box is located on the mold cavity 3. At this time, the upper mold 2 moves up. During the upward movement, the baffle 10 is retracted to make way for the outlet 9 position, and the air compressor generates negative pressure in the chamber 8 to adsorb the adjacent lunch box on the punch 4. At the same time, the top plate 5 at the bottom of the mold cavity 3 moves upward to push the aluminum foil lunch box upward. After rising to a certain height, the air compressor blows the aluminum foil lunch box in the opposite direction, and the top plate 5 no longer moves up, so that the aluminum foil lunch box falls from the punch 4 and is taken out. Then the top plate 5 and the baffle 10 are reset and the punching process is performed again.

[0019] A plurality of guide posts 11 are provided on the lower die 1, a plurality of guide sleeves 12 are provided under the upper die 2, springs 13 are sleeved on the guide posts 11, the guide posts 11 and the guide sleeves 12 cooperate to complete the positioning of the upper die 2 and the upper die 2, so that the stamping position is accurate, the springs 13 reduce the impact force when the upper die 2 moves downward, and assist the upper die 2 to move upward in the release stage.

[0020] A cavity 14 is provided in the lower mold 1. When the connecting plate 6 contacts the bottom of the cavity 14, the upper end surface of the top plate 5 fits with the mold cavity 3. When the punch 4 is pressed down, the connecting plate 6 can withstand the force to avoid damage to the plating liquid hydraulic cylinder. After the top plate 5 fits with the mold cavity 3, it is ensured that the stamped aluminum foil lunch box meets the requirements.

[0021] A plurality of baffle rods 10 are connected to a fixed plate 15 located in the chamber 8. When the fixed plate 15 contacts the bottom of the chamber 8, the lower surface of the baffle rod 10 is flush with the lower surface of the punch 4. The fixed plate 15 is raised and lowered by a second hydraulic cylinder 16. The outlet 9 is an inverted cone structure with a small outside and a large inside. The lower end of the baffle rod 10 matches the shape of the outlet 9.

[0022] During stamping, the second hydraulic cylinder 16 controls the fixed plate 15 to move down and contact the bottom of the chamber 8. At this time, the lower end of the baffle rod 10 is flush with the lower surface of the punch 4, and the bottom of the stamped aluminum foil lunch box is flat. The inverted cone structure of the outlet 9 is conducive to the retraction of the baffle rod 10 to open the outlet 9 and close the outlet 9 when the baffle rod 10 moves down.

[0023] Compared with the prior art, the utility model has the following beneficial effects: unloading mechanisms are simultaneously arranged on the lower mold and the upper mold, which act together on the formed aluminum foil lunch box to enable it to be demoulded smoothly without damage or deformation, thereby ensuring the integrity of the product and smoothly demoulding it, thereby improving production efficiency.
