Description

Technical Field

[0001] This utility model belongs to the field of aluminum foil lunch box processing technology, and in particular relates to an ejection structure of an aluminum foil lunch box processing mold. Background Technology

[0002] Aluminum foil lunch boxes are a widely used type of tableware. The thickness of aluminum foil lunch boxes is generally between 0.03mm and 0.20mm, and they can be divided into wrinkled and unwrinkled types, as well as disposable and reusable types. In China, they are often called tin foil lunch boxes. In reality, they are made from 3-series or 8-series aluminum ingots, which are cold-rolled or hot-rolled into aluminum foil master rolls with uniform thickness, a smooth surface, no pinholes, no dust particles, and no odor. These are then produced through a fully automated one-time cold stamping process using specialized equipment and molds.

[0003] Existing equipment has limitations in its use, making it difficult to quickly and conveniently change the processing mold according to different size requirements. This results in insufficient flexibility to meet subsequent processing standards and makes it difficult to eject the processed aluminum foil lunch boxes from the mold frame for recycling, thus affecting processing efficiency to some extent. Therefore, we propose an ejection structure for aluminum foil lunch box processing molds. Utility Model Content

[0004] The purpose of this utility model is to provide an ejection structure for an aluminum foil lunch box processing mold. Through a snap-fit ​​mechanism, it solves the problem that it is not convenient to quickly and easily change the processing mold according to different size requirements, which leads to insufficient flexibility in responding to subsequent processing standards and makes it difficult to eject the processed aluminum foil lunch box from the mold frame for recycling, thus affecting the processing efficiency to a certain extent.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an ejection structure for an aluminum foil lunchbox processing mold, comprising a processing base, a mold groove formed on the inner wall of the processing base, several support legs fixedly connected to the bottom outer wall of the processing base, several support rods fixedly connected to the top outer wall of the processing base, a top plate fixedly connected to the bottom outer wall of the support rods, a replacement mechanism provided on the inner wall of the top plate, the replacement mechanism including a telescopic rod, the outer wall of the telescopic rod being fixedly connected to the inner wall of the top plate, a mounting base fixedly connected to the bottom outer wall of the telescopic rod, and an ejection mechanism provided on the bottom outer wall of the processing base, the ejection mechanism including a rotating shaft seat, a transmission rod rotatably connected to the inner wall of the rotating shaft seat, and a handle fixedly connected to the outer wall of the transmission rod.

[0007] The above technical solution allows the transmission rod to be fixed in one position and rotated using a rotating shaft seat.

[0008] Furthermore, the inner wall of the mounting base is provided with a mounting groove, and a pressure plate is slidably connected to the inner wall of the mounting groove.

[0009] The above technical solution allows the pressure plate to slide within a fixed range using the mounting groove.

[0010] Furthermore, a sliding rod is fixedly connected to the inner wall of the mounting groove, and several buckles are slidably connected to the outer wall of the sliding rod.

[0011] The above technical solution allows several latches to slide within a fixed range using a sliding rod.

[0012] Furthermore, the outer wall of the buckle is slidably connected to the inner wall of the mounting groove, a spring is fixedly connected to the outer wall of the buckle, and a mold frame is slidably connected to the inner wall of the mold groove.

[0013] The above technical solution allows the mold frame to slide within a fixed range using the mold groove.

[0014] Furthermore, a crankshaft is fixedly connected to the outer wall of the end of the transmission rod away from the throttle, and a slider is rotatably connected to the outer wall of the crankshaft.

[0015] The above technical solution allows the crankshaft to transmit the power of the transmission rod's rotation to the slider, causing it to rotate.

[0016] Furthermore, a second sliding rod is slidably connected to the inner wall of the slider, and several connecting plates are fixedly connected to the outer wall of the second sliding rod.

[0017] By using the above technical solution, the slider can be made to slide within a fixed range using the second slider.

[0018] Furthermore, a fixed shaft is fixedly connected to the outer wall of the connecting plate, and a top rod is fixedly connected to the top outer wall of the fixed shaft.

[0019] The above technical solution allows the force on the connecting plate to be transmitted to the push rod via a fixed shaft, enabling it to slide.

[0020] Furthermore, the inner wall of the mold frame is provided with a push rod groove, and the inner wall of the push rod groove is slidably connected to the outer wall of the push rod.

[0021] The above technical solution allows the push rod to slide within a fixed range by utilizing the push rod groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model, by setting up buckles, firstly moves the mold frame directly upward from the mold groove, then places the replacement mold frame in, ensuring it fits snugly against the mold groove. Then, several buckles are pinched together and brought close to each other. When the buckles are close together, they compress the spring, at which point the pressure plate is no longer held in place by the buckles. Then, the pressure plate is moved outward to replace the appropriate pressure plate. The buckles will keep each other away under the action of the spring, thus holding the pressure plate in place and preventing it from sliding. This achieves the function of quickly and conveniently changing the processing mold according to different size requirements to meet subsequent processing standards.

[0024] 2. This utility model incorporates a push rod. Once the pressure plate rises and no longer presses down on the aluminum foil, rotating the handle drives the transmission rod, which in turn drives the crankshaft. The crankshaft then drives the slider, which rotates around the transmission rod. The slider then drives the slide rod to rotate, which in turn drives several connecting plates to rise. These connecting plates then drive the fixed shaft to rise, which in turn drives the push rod to rise. During this upward movement, the push rod ejects the formed aluminum foil lunch box from the mold frame. This design allows the formed aluminum foil lunch box to be ejected from the mold frame for easy recycling, saving manpower and improving processing efficiency.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Several support rods 103 are fixedly connected to the top outer wall of the processing base 1. A top plate 104 is fixedly connected to the bottom outer wall of the support rods 103, primarily supporting and fixing the top plate 104. A replacement mechanism 2 is provided on the inner wall of the top plate 104, including a telescopic rod 201. The outer wall of the telescopic rod 201 is fixedly connected to the inner wall of the top plate 104. The top plate 104 mainly serves to fix and limit the telescopic rod 201, ensuring that the telescopic rod 201 is in a fixed position. The bottom outer wall of the telescopic rod 201 is fixedly connected to the mounting base 202. The bottom outer wall of the processing base 1 is provided with an ejection mechanism 3. The ejection mechanism 3 includes a rotating shaft seat 301. The inner wall of the rotating shaft seat 301 is rotatably connected to the transmission rod 302. The rotating shaft seat 301 mainly serves to fix and limit the transmission rod 302. The transmission rod 302 can only rotate in a fixed position. The outer wall of the transmission rod 302 is fixedly connected to the handle 303.

[0036] Several support legs 102 support and fix the processing base, and several support rods 103 mainly support and fix the top plate 104. The top plate 104 ensures that the telescopic rod 201 is in a fixed position, and the rotating shaft seat 301 allows the transmission rod 302 to rotate only in a fixed position.

[0037] The inner wall of the mounting base 202 is provided with a mounting groove 203. A pressure plate 204 is slidably connected to the inner wall of the mounting groove 203. A slide rod 205 is fixedly connected to the inner wall of the mounting groove 203. The outer wall of the pressure plate 204 fits very closely with the inner wall of the mounting groove 203. The mounting groove 203 restricts the pressure plate 204 to slide at a fixed angle. Several buckles 206 are slidably connected to the outer wall of the slide rod 205. The outer wall of the buckles 206 is slidably connected to the inner wall of the mounting groove 203. The buckles 206 can only slide within the mounting groove 203. A spring 207 is fixedly connected to the outer wall of the buckles 206. A mold frame 208 is slidably connected to the inner wall of the mold groove 101. The spring 207 continuously applies a supporting force between the several buckles 206 due to its own physical properties.

[0038] The mounting slot 203 restricts the pressure plate 204 to slide at a fixed angle, and the mounting slot 203 restricts the buckle 206 to slide within a fixed range. The spring 207 continuously applies a supporting force between several buckles 206.

[0039] A crankshaft 304 is fixedly connected to the outer wall of the end of the transmission rod 302 away from the throttle 303. A slider 305 is rotatably connected to the outer wall of the crankshaft 304. When the crankshaft 304 rotates, the slider 305 will rotate together with it. A second slider 306 is slidably connected to the inner wall of the slider 305. Several connecting plates 307 are fixedly connected to the outer wall of the second slider 306. A fixed shaft 308 is fixedly connected to the outer wall of the connecting plate 307. When the connecting plate 307 moves, the fixed shaft 308 will move together with the connecting plate 307. A top rod 309 is fixedly connected to the top outer wall of the fixed shaft 308. A top rod groove 310 is opened on the inner wall of the frame 208. The inner wall of the top rod groove 310 is slidably connected to the outer wall of the top rod 309. The outer wall of the top rod 309 will fit very closely with the inner wall of the top rod groove 310. The top rod 309 can only move within a fixed range.

[0040] The slider 305 rotates together with the crankshaft 304, and the fixed shaft 308 moves together with the connecting plate 307. The push rod groove 310 restricts the push rod 309 to move only within a fixed range.

[0041] One specific application of this embodiment is:

[0042] When the operator needs to use the equipment, the mold can be changed according to different size requirements. First, the mold frame 208 is moved upwards directly from the mold slot 101. Then, the replacement mold frame 208 is placed in, ensuring it fits snugly against the mold slot 101. Next, several buckles 206 are pinched together and brought closer to each other. When the buckles 206 are close together, they will compress the spring 207. At this time, the pressure plate 204 is no longer held in place by the buckles 206. Then, the pressure plate 204 is moved outwards and replaced with a suitable pressure plate 204. The buckles 206 will be kept apart from each other under the action of the spring 207 to hold the pressure plate 204 in place, preventing it from sliding. The unprocessed aluminum foil is placed on the mold frame 208, ensuring that the pressure plate 204 is directly above the aluminum foil. The telescopic rod 201 is then activated. The mounting base 202 moves downward, which in turn moves the pressure plate 204 downward. The pressure plate 204 applies pressure to the aluminum foil sheet, pressing it into the mold frame 208 to form the aluminum foil. Once the pressure plate 204 rises and no longer presses down on the aluminum foil sheet, the handle 303 is rotated. The handle 303 drives the transmission rod 302 to rotate, which in turn drives the crankshaft 304 to rotate. The crankshaft 304 drives the slider 305 to rotate, which then rotates around the transmission rod 302. The slider 305 drives the slide bar 306 to rotate, which in turn drives several connecting plates 307 to rise. The connecting plates 307 drive the fixed shaft 308 to rise, which in turn drives the push rod 309 to rise. During the rising process, the push rod 309 pushes the formed aluminum foil lunch box out of the mold frame 208.
