[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 4 It can be seen that an aluminum foil lunch box stamping and forming device includes a stamping machine, which includes a workbench 1, on which a corresponding lower mold 2 and an upper mold 3 are installed, and a blowing mechanism located on the side of the upper mold 3 is provided on the workbench 1, and the blowing mechanism includes a bracket 4, on which an air cylinder 5 is provided, and a piston 6 is telescopically provided in the air cylinder 5, and a guide column 7 extending out of the air cylinder 5 is connected to the piston 6, and the guide column 7 is connected to the upper mold 3 via a connecting rod 8, and an air outlet 9 and an air inlet 10 are respectively provided on both sides of the upper end of the air cylinder 5, and the air outlet 9 is connected to the nozzle 12 via a pipeline 11, and the nozzle 12 faces the mold cavity direction of the lower mold 2.

[0018] When the utility model is used in a specific way,

[0019] The blowing mechanism is installed on the workbench 1, and then the equipment is started to perform stamping processing on the aluminum foil lunch box. The upper mold 3 reciprocates vertically during the stamping process, and drives the piston 6 to retract and retract in the air cylinder 5 through the connecting rod 8. When the upper mold 3 moves up, the piston 6 moves up in the air cylinder 5, and the gas in the air cylinder 5 enters the nozzle 12 through the pipeline 11 to blow air in the direction of the mold cavity. At this time, the formed aluminum foil lunch box just falls off from the upper mold 3 and is blown away from the mold cavity position for the next stamping molding.

[0020] A mounting hole 13 is provided on one side of the upper mold 3, and the connecting rod 8 is connected to a screw 14 threadedly connected to the mounting hole 13, forming a structure connecting the piston 6 and the upper mold 3. The screw 14 is detachably installed on the side of the upper mold 3 and is connected to the piston 6 through the connecting rod 8. In this way, the blowing mechanism can be removed for maintenance when it is not in working state, which will not affect the normal use and manufacturing processes of the stamping equipment. It can achieve the blowing effect and can be dismantled when not in use. It is convenient to disassemble and assemble and use.

[0021] A conduit 15 is provided on the bracket 4, and the conduit 15 is in a horizontal state. A gap is provided between the conduit 15 and the workbench 1, and a nozzle 12 is provided on the conduit 15. There are multiple nozzles 12 and they correspond one to one with the mold cavities. The nozzles 12 on the conduit 15 can be set as needed, and a position can be reserved on the conduit 15. Different numbers and positions of nozzles 12 can be installed for different molds, so that the equipment can be universal.

[0022] The air outlet 9 and the air inlet 10 are both provided with rubber plugs 16, so that both the air outlet 9 and the air inlet 10 have a one-way flow structure. The flow direction of the air outlet 9 is from the air cylinder 5 to the pipeline 11, and the flow direction of the air inlet 10 is from the outside to the inside of the air cylinder 5. An exhaust hole 17 is provided at the bottom of the air cylinder 5.

[0023] The structure of the air cylinder 5 is similar to that of the air pump 5 in daily life. The intermittent eruption of gas is achieved through the reciprocating motion of the piston 6. When the gas erupts, the upper mold 3 moves up and is just in the demoulding state, achieving perfect unification, and blowing the formed aluminum foil lunch box out of the mold cavity so that the next stamping can be carried out smoothly.

[0024] Compared with the prior art, the utility model has the following beneficial effects: no external air source is required, the vertical reciprocating motion of the punching machine is converted into the motion of the piston in the air cylinder, intermittent air jet is realized, and it perfectly cooperates with the punching process to blow the formed aluminum foil lunch box away from the mold cavity so as to complete the next punching.
