Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leather cutting technology, and in particular relates to a leather shoe upper cutting mold. Background Technology
[0002] Leather shoe upper cutting dies are tools used to cut various parts of leather shoe uppers. They are usually made according to shoe design drawings or patterns to improve cutting efficiency, precision, and consistency. Cutting dies are a crucial part of the shoemaking process, especially in mass production.
[0003] When cutting leather, the upper mold is usually pushed by a hydraulic rod to move the cutting blade to the lower mold, thereby completing the cutting of the leather. However, during the cutting process, the leather is elastic or has strong sliding properties and may slide into the cutting groove, causing the cutting position to deviate and affecting the accuracy of the cutting. Therefore, we have proposed a leather shoe upper cutting mold. Utility Model Content
[0004] The purpose of this utility model is to provide a leather shoe upper cutting mold. The cutting mechanism descends, causing the spring to be stretched. The reaction force of the spring will apply a downward force to the limiting plate. The limiting plate transmits the force to the pressure plate, and the pressure plate transmits the force to the limiting rod, which can fix the leather. This solves the problem that the leather has elasticity or strong sliding properties and slides into the cutting groove, causing the cutting position to deviate and affecting the cutting accuracy.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a leather shoe upper cutting mold, including an operating table, a lower mold fixedly connected to the top of the operating table, a cutting groove at the top of the lower mold, a cutting mechanism above the operating table, a smoothing mechanism above the lower mold, and a feeding mechanism above the operating table.
[0007] The cutting mechanism includes a fixed frame, the bottom of which is fixedly connected to the top of the operating table. A first groove is formed on the fixed frame, and a first sliding rod is fixedly connected inside the first groove. A sliding plate is slidably connected to the outer wall of the first sliding rod. A hydraulic rod is rotatably connected to the top of the fixed frame, and the output end of the hydraulic rod is sleeved inside the fixed frame. A fixed plate is fixedly connected to the output end of the hydraulic rod. The outer wall of the fixed plate is fixedly connected to the side of the sliding plate closest to the center of the fixed frame. An upper mold is fixedly connected to the side of the fixed plate closest to the lower mold. A cutting blade is fixedly connected to the top wall of the upper mold. A limiting rod is slidably connected inside the upper mold, and its top end penetrates the top of the upper mold and extends thereafter. A pressure plate is fixedly connected to the end of the limiting rod closest to the lower mold. A limiting piece is fixedly connected to the end of the limiting rod away from the pressure plate. A first spring is fixedly connected to the end of the limiting piece closest to the limiting rod, and the limiting rod is located inside the first spring. The end of the first spring away from the limiting piece is fixedly connected to the top of the upper mold.
[0008] Furthermore, the smoothing mechanism includes a second slide bar, which is fixedly connected to the inner wall of the fixed frame, and a first slider is slidably connected to the outer wall of the second slide bar. A mounting bracket is fixedly connected to the top of the first slider.
[0009] Furthermore, the mounting bracket has a second sliding groove, a third sliding rod is fixedly connected inside the second sliding groove, and a second slider is slidably connected to the outer wall of the third sliding rod.
[0010] Furthermore, a second spring is fixedly connected to the top of the second slider, and the end of the second spring away from the second slider is fixedly connected to the inside of the second groove. A smoothing roller is rotatably connected to the side of the second slider near the lower mold.
[0011] Furthermore, a connecting rod is rotatably connected to the top of the mounting frame, and the end of the connecting rod away from the mounting frame is rotatably connected to the bottom of the slide plate.
[0012] Furthermore, the feeding mechanism includes a mounting plate, and a mounting rod is rotatably connected to the front of the mounting plate.
[0013] Furthermore, there are two mounting plates. A one-way brake motor is fixedly connected to the back of the right mounting plate, and the output end of the one-way brake motor is rotatably connected inside the right mounting plate.
[0014] Furthermore, the output end of the unidirectional brake motor is fixedly connected to the right mounting rod via a coupling, a support frame is fixedly connected to the top of the operating table, and a guide roller is rotatably connected to the inner wall of the support frame.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model uses the downward movement of the hydraulic rod output end to drive the fixed plate downward. The fixed plate drives the slide plate downward along the first slide rod. When the fixed plate descends, it also drives the upper mold downward. The upper mold drives the cutting blade downward, and the limiting rod, pressure plate, limiting piece, and spring also descend accordingly. Since the bottom height of the pressure plate is lower than the height of the cutting blade, the pressure plate will contact the leather first. As the hydraulic rod output end continues to descend, the pressure plate will be blocked by the leather, while the upper mold of the cutting blade will continue to descend, thus stretching the spring. The reaction force of the spring will apply a downward force to the limiting piece, which is transmitted to the pressure plate, and then to the limiting rod. Thus, the leather can be fixed by the pressure plate, effectively preventing the leather from sliding into the cutting groove during the cutting process due to its elasticity or strong sliding properties, which would cause the cutting position to shift and affect the cutting accuracy.
[0017] 2. This utility model uses a fixed plate to drive the slide plate down along the first slide bar. The descent of the first slide bar will cause the top of the connecting rod to descend, and the bottom of the connecting rod will push the mounting frame to move the first slider along the second slide bar. At the same time, the mounting frame will drive the second slider to move, and the second slider will drive the smoothing roller to move, thereby moving the smoothing roller along the leather, which can effectively smooth the leather, prevent the leather from wrinkling, and further improve the accuracy of leather cutting.
[0018] 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

[0029] Please see Figure 1-6 As shown, this utility model is a leather shoe upper cutting mold, including an operating table 1, a lower mold 11 fixedly connected to the top of the operating table 1, a cutting groove 12 starting from the top of the lower mold 11, a cutting mechanism 2 provided above the operating table 1, a smoothing mechanism 3 provided above the lower mold 11, and a feeding mechanism 4 provided above the operating table 1.
[0030] The cutting mechanism 2 includes a fixed frame 201, the bottom of which is fixedly connected to the top of the operating table 1.

An upper mold 207 is fixedly connected to the fixed plate 206 near the lower mold 11, and a cutting tool is fixedly connected to the top wall of the upper mold 207. The blade 208 can be moved to the lower mold 11 by the upper mold 207. The upper mold 207 has a sliding connection of a limit rod 209. The top of the limit rod 209 passes through the top of the upper mold 207 and extends thereto. The end of the limit rod 209 near the lower mold 11 is fixedly connected to a pressure plate 210, which can fix the leather. The end of the limit rod 209 away from the pressure plate 210 is fixedly connected to a limit piece 211, which can prevent the limit rod 209 from separating from the upper mold 207. The end of the limit piece 211 near the limit rod 209 is fixedly connected to a first spring 212. The limit rod 209 is located inside the first spring 212.

[0031] The smoothing mechanism 3 includes a second slide rod 301, which is fixedly connected to the inner wall of the fixed frame 201. A first slider 302 is slidably connected to the outer wall of the second slide rod 301. The second slide rod 301 can limit the movement of the first slider 302. A mounting frame 303 is fixedly connected to the top of the first slider 302. The movement of the mounting frame 303 can drive the first slider 302 to move, improving the stability of the mounting frame 303 during movement. A second groove 304 is formed on the mounting frame 303. A third slide rod 305 is fixedly connected inside the second groove 304. The outer wall of the third slide rod 305 is slidably connected to... A second slider 306 is connected, and a second spring 307 is fixedly connected to the top of the second slider 306. The second spring 307 can be moved by the movement of the second slider 306. The end of the second spring 307 away from the second slider 306 is fixedly connected to the inside of the second slide groove 304. A smoothing roller 308 is rotatably connected to the side of the second slider 306 near the lower mold 11. The smoothing roller 308 can smooth the leather and prevent wrinkles from forming.

The end of the connecting rod 309 away from the mounting bracket 303 is rotatably connected to the bottom of the slide plate 204.
[0032] The feeding mechanism 4 includes a mounting plate 401. A mounting rod 402 is rotatably connected to the front of the mounting plate 401. There are two mounting plates 401. A one-way brake motor 403 is fixedly connected to the back of the right mounting plate 401. The output end of the one-way brake motor 403 is rotatably connected inside the right mounting plate 401. The operation of the one-way brake motor 403 can drive the right mounting rod to rotate, thereby feeding. The output end of the one-way brake motor 403 is fixedly connected to the right mounting rod 402 through a coupling. A support frame 404 is fixedly connected to the top of the operating table 1. A guide roller 405 is rotatably connected to the inner wall of the support frame 404.
[0033] One specific application of this embodiment is:
[0034] In use, the roll containing leather is fixed to the left mounting rod 402, and the blank roll is fixed to the right mounting rod 402. The leather is then passed over the guide roller 405 and under the smoothing roller 308 and fixed to the blank roll. As the leather passes over the smoothing roller 308, it pushes the smoothing roller 308 downwards. The smoothing roller 308 moves the second slider 306, thereby compressing the second spring 307. The reaction force of the second spring 307 allows the smoothing roller 308 to adhere to the leather. Because the height of the smoothing roller 308 is level with the top of the lower mold 11, and the height of the smoothing roller 308 is higher... At the height of the mounting rod 402, the leather can be given a certain tension to reduce wrinkles. Then, the output end of the hydraulic rod 205 is lowered. The lowering of the output end of the hydraulic rod 205 drives the fixing plate 206 to descend. The fixing plate 206 drives the slide plate 204 to descend along the first slide rod 203. The descent of the first slide rod 203 will drive the top end of the connecting rod 309 to descend. The bottom end of the connecting rod 309 will push the mounting frame 303 to drive the first slider 302 to move along the second slide rod 301. At the same time, the mounting frame 303 will drive the second slider 306 to move. The second slider 306 will drive the smoothing roller 308 to move, thereby causing the smoothing roller 308 to move. 8. Moving along the leather effectively smooths it out, further preventing wrinkles that could affect the accuracy of cutting. As the fixed plate 206 descends, it also lowers the upper mold 207, which in turn lowers the cutting blade 208. The limiting rod 209, pressure plate 210, limiting piece 211, and spring 212 also descend accordingly. Since the bottom of the pressure plate 210 is lower than the cutting blade 208, it will contact the leather first. As the hydraulic rod 205 continues to descend, the pressure plate 210 will be blocked by the leather, while the upper mold 207 will continue to descend, thus causing the spring 208 to... When spring 212 is stretched, the reaction force of spring 212 will apply a downward force to the limiting plate 211. The limiting plate 211 transmits the force to the pressure plate 210, and the pressure plate 210 transmits the force to the limiting rod 209. Thus, the leather can be fixed by the pressure plate 210, which effectively prevents the leather from sliding into the cutting groove during the cutting process due to its elasticity or strong sliding properties, which would cause the cutting position to deviate and affect the cutting accuracy. After the cutting is completed, the one-way brake motor 403 is started. The one-way brake motor 403 drives the drum on the right mounting rod 402 to rotate, thereby moving the uncut part of the leather onto the lower mold 11.
