Description

Technical Field

[0001] This utility model relates to the field of hot pressing of eyelet pieces, specifically a male and female mold hot pressing device. Background Technology

[0002] Eyelet hot pressing refers to using a hot pressing machine to bond the eyelet to the upper material under appropriate temperature and pressure to ensure the accuracy and firmness of the eyelet position. Special eyelet male and female molds are required when performing eyelet hot pressing.

[0003] However, when the existing male and female molds are placed under the hot press, they will be displaced due to the downward pressure of the hot press, which will cause defects in the finished eyelet pieces. This requires workers to remake them, which wastes production materials and also affects production efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a male and female mold hot pressing device that can provide a more stable clamping function for the male and female molds of shoe eyelets, thereby effectively reducing the probability of defective products during hot pressing, saving production raw materials, and increasing the production efficiency of the factory.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a male and female mold hot pressing device, comprising a hot pressing device base and a movable plate. A support platform is fixed to the top of the hot pressing device base, and two sets of movable plates are arranged inside the support platform. Two sets of sliding rods pass through the top of the two sets of movable plates, and a clamping plate is fixed to one end of the two sets of sliding rods near the vertical central axis of the hot pressing device base. A rubber pad is attached to one end of the clamping plate near the vertical central axis of the hot pressing device base. Springs are sleeved on the outside of the two sets of sliding rods, and one end of the two sets of springs is fixedly connected to the movable plate, and the other end of the two sets of springs is pressed against the clamping plate.

[0006] By adopting the above technical solution, the movable plate is used to drive the two sets of sliding rods, two sets of springs, two sets of clamping plates and rubber pads inside to move synchronously. The clamping plates provide clamping function for the eyelet mold through the rubber pads. Two sets of springs are sleeved on the outside of the two sets of sliding rods to provide relative pressure when the clamping plates clamp the eyelet mold. In addition, the two sets of sliding rods have an elastic telescopic structure inside the movable plate, so that the clamping plates have better clamping adaptability.

[0007] Furthermore, the bottom of the hot pressing device base is fixed with several sets of support feet, the inner side of the load-bearing platform is fixed with a workbench, and a first fixing plate is fixed on one side of the inner side of the load-bearing platform, and a second fixing plate is fixed on the other side of the inner side of the load-bearing platform.

[0008] By adopting the above technical solution, several sets of support feet can provide stable support for the base of the hot pressing device. The worktable is used to place the eyelet mold, and the first and second fixing plates can provide installation space for the adjusting rod, the limiting rod and the drive motor.

[0009] Furthermore, an adjusting rod is rotatably installed through one side of the inside of the workbench, and a limiting rod is installed through the other side of the inside of the workbench.

[0010] By adopting the above technical solution, the adjusting rod can be located inside the worktable and will not interfere with the stability of the worktable when it rotates. In addition, the limiting rod runs through the inside of the worktable, which can limit the movement of the adjusting rod and the moving plates on both sides of the limiting rod.

[0011] Furthermore, the two ends of the adjusting rod are provided with two sets of threads in opposite directions, which are respectively threaded to two sets of moving plates, and the two sets of moving plates are slidably connected to the limiting rod.

[0012] By adopting the above technical solution, the two ends of the adjusting rod are provided with two sets of threaded groups in opposite directions. This arrangement allows the threaded groups at both ends of the adjusting rod to be threadedly connected to the two sets of moving plates when the adjusting rod rotates, thereby driving the two sets of moving plates to move synchronously in opposite directions. The two sets of moving plates are slidably connected to the limiting rod. This arrangement ensures that the moving plates can move stably along the axis of the limiting rod during the movement process.

[0013] Furthermore, a drive motor is provided on the side of the first fixed plate away from the worktable, and the output end of the drive motor is connected to the adjusting rod, and the other end of the adjusting rod is rotatably connected to the second fixed plate. A limit rod is fixed on the side of the first fixed plate close to the worktable, and the other end of the limit rod is fixedly connected to the second fixed plate.

[0014] By adopting the above technical solution, the driving motor can automatically drive the adjusting rod. The limiting rod is fixed at both ends to the first fixed plate and the second fixed plate, respectively, so that the moving plate can be limited by the limiting rod during the movement, preventing the moving plate from deviating during the movement.

[0015] Furthermore, two sets of support blocks are fixed at both ends of the load-bearing platform, and two sets of support columns are fixed at the top of the two sets of support blocks respectively. A top plate is installed on the top of the four sets of support columns, and a cylinder is provided on the top of the top plate. A hot pressing assembly is installed at the output end of the cylinder.

[0016] By adopting the above technical solution, the two sets of support blocks and four sets of support columns can achieve the function of stabilizing the top plate, and the cylinder and hot pressing assembly can achieve the function of automatically hot pressing the eyelet mold.

[0017] Furthermore, four sets of auxiliary rods are fixed to the top of the workbench and are slidably connected to the hot pressing assembly.

[0018] By adopting the above technical solution and using the four sets of auxiliary rods, the hot-pressed assembly can be stably guided, thus increasing the stability of the device.

[0019] Furthermore, both the cylinder and the drive motor are electrically connected to the control center.

[0020] By adopting the above technical solution and through the set control center, the function of automatic control of cylinders and drive motors can be realized. The working status of cylinders and drive motors can be controlled simply through the control center, which is simple and convenient to operate and improves the working efficiency of the device.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. In this utility model, the adjusting rod is threadedly connected to two sets of moving plates, and the threads on the outer sides of both ends of the adjusting rod are set in opposite directions, so that the two sets of moving plates can move synchronously in opposite directions, thereby allowing the clamping plates at the inner ends of the two sets of sliding rods inside the moving plates to provide a stable clamping function for the male and female eyelet molds above the worktable.

[0023] 2. By setting a rubber pad, this utility model can provide a more stable frictional force when the clamping plate holds the male and female molds through the rubber pad, thereby preventing the male and female molds from sliding and displacing when they come into contact with the clamping plate.

[0024] 3. By incorporating a spring, this utility model allows the clamping plate to have an elastic telescopic structure when clamping the male and female molds via the rubber pad. This enables the clamping plate to provide thrust to the male and female molds through the spring, resulting in better stability for the male and female molds. Attached Figure Description

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] In this embodiment:

[0035] A male and female mold hot pressing device, such as Figures 1-4As shown, the device includes a hot press base 1 and a movable plate 9. A load-bearing platform 3 is fixed on the top of the hot press base 1, and two sets of movable plates 9 are arranged inside the load-bearing platform 3. Two sets of sliding rods 10 pass through the top of the two sets of movable plates 9, and a clamping plate 11 is fixed at one end of the two sets of sliding rods 10 near the vertical central axis of the hot press base 1. A rubber pad 13 is attached to one end of the clamping plate 11 near the vertical central axis of the hot press base 1. Springs 12 are sleeved on the outside of the two sets of sliding rods 10, and one end of the two sets of springs 12 is fixedly connected to the movable plate 9, and the other end of the two sets of springs 12 is pressed against the clamping plate 11.

[0036] One end of the spring 12 is fixedly connected to the movable plate 9, and the other end is pressed against the clamping plate 11. Through the elastic extension and contraction function of the spring 12, the clamping plate 11 can provide buffer clamping when holding the eyelet mold, preventing wear on the outer wall of the eyelet mold caused by direct hard clamping. This improves the effectiveness of the device. Simultaneously, the spring 12 also provides a reset function for the clamping plate 11, allowing it to quickly reset after being released from the eyelet mold, facilitating subsequent use. The clamping of the eyelet mold increases the convenience of the device. The slide bar 10 is used to limit the extension and retraction of the spring 12. In addition, a rubber pad 13 is attached to one end of the clamping plate 11 near the central axis of the hot pressing device base 1. The rubber pad 13 is soft and has high friction, which increases the friction between the clamping plate 11 and the eyelet mold when clamping it. This prevents the eyelet mold from slipping during clamping, which would affect the hot pressing effect and improve the practicality of the device.

[0037] See Figure 1 and Figure 2 The bottom of the hot press base 1 is fixed with several sets of support feet 2, the inner side of the load-bearing platform 3 is fixed with a worktable 4, and the inner side of the load-bearing platform 3 is fixed with a first fixing plate 5, and the inner other side of the load-bearing platform 3 is fixed with a second fixing plate 6.

[0038] The base 1 of the hot press device is stably supported by several sets of support feet 2. The first fixing plate 5 and the second fixing plate 6 are provided, and the adjusting rod 7 is movably installed inside the first fixing plate 5 and the second fixing plate 6 through bearings. The adjusting rod 7 can rotate stably. At the same time, the inner side of the first fixing plate 5 and the second fixing plate 6 is fixed with a limit rod 8, which can provide a good fixing environment for the limit rod 8.

[0039] See Figure 1 , Figure 2 and Figure 3 An adjusting rod 7 is rotatably installed through one side of the inside of the workbench 4, and a limiting rod 8 is installed through the other side of the inside of the workbench 4.

[0040] The adjusting rod 7, which is rotated inside the worktable 4, and the limiting rod 8, which passes through the inside of the worktable 4, can reduce the impact on the space above the worktable 4 by passing through the inside of the worktable 4.

[0041] See Figure 2 , Figure 3 and Figure 4 The two ends of the adjusting rod 7 are provided with two sets of threads in opposite directions, which are respectively threaded to two sets of moving plates 9, and the two sets of moving plates 9 are slidably connected to the limiting rod 8.

[0042] The adjusting rod 7 has two sets of threads in opposite directions at both ends, which are threaded to the two sets of moving plates 9 respectively. By utilizing the transmission characteristics of the threads, the precise control of the two sets of moving plates 9 is achieved, thereby driving the two sets of moving plates 9 to move synchronously in opposite directions. The two sets of moving plates 9 are slidably connected to the limiting rod 8, which can prevent the moving plates 9 from deviating or shaking during the movement, thereby further improving the stability and clamping accuracy of the device.

[0043] See Figure 1 , Figure 2 and Figure 3 A drive motor 14 is provided on the side of the first fixed plate 5 away from the worktable 4, and the output end of the drive motor 14 is connected to the adjusting rod 7. The other end of the adjusting rod 7 is rotatably connected to the second fixed plate 6. A limit rod 8 is fixed on the side of the first fixed plate 5 close to the worktable 4, and the other end of the limit rod 8 is fixedly connected to the second fixed plate 6.

[0044] In this device, simply turning on the drive motor 14 via the control center will cause the drive motor 14 to rotate the adjusting rod 7. During the rotation of the adjusting rod 7, the two sets of reverse threads at both ends will drive the two sets of moving plates 9 to move synchronously in opposite directions. This will cause both sets of moving plates 9 to move the clamping plate 11 towards the vertical central axis of the worktable 4, thereby quickly clamping the eyelet mold and improving the working efficiency of the device. The first fixed plate 5 is fixed with a limit rod 8 on the side near the worktable 4, and the other end of the limit rod 8 is fixedly connected to the second fixed plate 6, giving the limit rod 8 better stability.

[0045] See Figure 1 Two sets of support blocks 15 are fixed at both ends of the load-bearing platform 3, and two sets of support columns 16 are fixed at the top of the two sets of support blocks 15 respectively. A top plate 17 is installed on the top of the four sets of support columns 16, and a cylinder 18 is provided on the top of the top plate 17. A hot press assembly 19 is installed at the output end of the cylinder 18.

[0046] The two sets of support blocks 15 and four sets of support columns 16 can prevent the top plate 17 from shaking during use, thus affecting the normal use of the device. By opening the cylinder 18 through the control center, the cylinder 18 can push the hot pressing assembly 19 downward to hot press the eyelet mold on the worktable 4.

[0047] See Figure 1 Four sets of auxiliary rods 20 are fixed on the top of the workbench 4 and are slidably connected to the hot press assembly 19;

[0048] The auxiliary rod 20 is slidably connected to the hot pressing assembly 19, which allows the hot pressing assembly 19 to be limited by the auxiliary rod 20 during movement, preventing the hot pressing assembly 19 from shaking during movement and affecting the hot pressing effect on the eyelet mold, thus improving the stability and practicality of the device.

[0049] See Figure 1 , Figure 2 and Figure 3 Both cylinder 18 and drive motor 14 are electrically connected to the control center;

[0050] Both cylinder 18 and drive motor 14 are electrically connected to the control center, which ensures that cylinder 18 and drive motor 14 can stably receive commands from the control center and work stably, thus improving the stability and practicality of the device.

[0051] The implementation principle of this utility model is as follows: First, the hot pressing device base 1 is stably placed in the designated position by the support foot 2. Then, the eyelet mold is placed above the workbench 4. The drive motor 14 is turned on by the control center, causing it to drive the adjusting rod 7 to rotate. The adjusting rod 7 drives the two sets of moving plates 9 to move synchronously in opposite directions through two sets of reverse threads at both ends, so that both sets of moving plates 9 move towards the vertical central axis of the workbench 4. At the same time, the limiting rod 8 provides a limiting assistance function by slidingly connecting with the moving plate 9. Then, the moving plate 9 moves inward so that the rubber pad 13 on the inner side of the clamping plate 11 provides a clamping function for the eyelet mold. The rubber pad 13 can increase the friction when the clamping plate 11 clamps the eyelet mold, preventing the eyelet mold from sliding and becoming displaced. The clamping plate 11 and the slide rod 10 form an integrated structure. At the same time, one end of the spring 12 is fixedly connected to the moving plate 9, and the other end of the spring 12 is pressed against the clamping plate 11, so that the spring 12 can provide elastic extension and contraction function for the clamping plate 11 and reset the clamping plate 11 when releasing the eyelet mold. The spring 12 is sleeved on the outside of the slide rod 10, which provides a limiting and stabilizing function for the spring 12. After the clamping plate 11 clamps the eyelet mold through the rubber pad 13, the cylinder 18 is opened through the control center to move the hot pressing assembly 19 downward. At the same time, the hot pressing assembly 19 is guided and limited by the auxiliary rod 20, so that the hot pressing assembly 19 can stably heat and press the eyelet mold on the lower worktable 4. Finally, after the heat pressing is completed, the eyelet mold can be removed.

[0052] Furthermore, the hot-pressed assembly 19 can be referred to as the prior art "200-hot-pressed assembly" in patent publication number: CN 209602371 U, and will not be elaborated further here.

[0053] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
