Description

Technical Field

[0001] This utility model relates to the field of shoemaking technology, specifically to a shoemaking mold air hole positioning device. Background Technology

[0002] In the shoe manufacturing process, the precise positioning of the air holes in the shoe mold directly affects the breathability, wearing comfort, and appearance quality of the finished shoe. Traditional manual positioning methods rely on the experience of operators, resulting in low efficiency, large errors, and poor consistency. They are unable to meet the dual demands of modern shoe manufacturing processes for precision and production capacity. Therefore, the industry is gradually promoting the use of automated air hole positioning devices to improve processing quality.

[0003] Existing shoe mold vent positioning devices typically employ a single positioning mechanism, such as simply drawing lines using a height gauge or using mechanical ejectors to directly contact the shoe mold surface for positioning. However, when drawing lines using a height gauge, operators need to repeatedly adjust the gauge height and manually mark the points, which is not only time-consuming and labor-intensive, but also highly susceptible to human error in line accuracy, easily resulting in line deviation or blurred markings. This leads to reliance on blurry reference lines during subsequent machining, further accumulating positioning errors. On the other hand, when using mechanical ejectors to directly contact the shoe mold surface, the rigid contact between the ejector and the mold is prone to displacement due to uneven placement of the mold, causing the positioning point to misalign with the actual vent center, resulting in a continuous decrease in positioning accuracy. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a shoe mold air hole positioning device to solve the technical problems of inaccurate and time-consuming air hole positioning in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shoe mold air hole positioning device for positioning the air holes of the shoe mold, including a support frame, an installation frame on the support frame, a connecting frame in the installation frame, and a sliding ball movably disposed in the connecting frame for moving the shoe mold.

[0007] Preferably, the support frame has a placement slot for mounting the mounting frame, and the connecting frame has a plurality of mounting slots, each mounting slot having a sliding ball movably disposed therein.

[0008] Preferably, the bottom of the mounting frame is provided with an XY axis feed stage, the output end of the XY axis feed stage is connected to a connecting seat, a cylinder is embedded in the connecting seat, and the output end of the cylinder is fixed with a tungsten steel tip that positions the air holes on the shoe mold.

[0009] Preferably, the connecting frame has several clearance grooves. When the tungsten carbide tip moves upward and passes through the clearance grooves, it comes into contact with the air holes on the shoe mold.

[0010] Preferably, the support frame is provided with a support base, the support base is provided with a drive motor, the output shaft of the drive motor is connected to a threaded rod through a coupling, and the threaded rod is externally threaded to a movable seat.

[0011] The top of the movable seat is fixed with a lifting frame, the top of the lifting frame is provided with a guide rail plate, and the infrared generator is movably mounted on the outside of the guide rail plate.

[0012] Preferably, the support frame is provided with a limiting rod, and the movable seat has a through hole for the limiting rod to pass through.

[0013] Preferably, two sets of mounting brackets are fixed to the top of the support frame, each set of mounting brackets has a guide rod fixed in it, and a movable frame is slidably arranged outside the two guide rods. A detachable brush roller is rotatably arranged in the movable frame. A handle is fixed to the top of the movable frame.

[0014] When the movable frame slides outside the guide rod, the brush roller abuts against the top of the support frame.

[0016] 1. This invention achieves precise marking of air hole positions through the coordinated operation of optical positioning and mechanical positioning. First, an infrared generator is used for preliminary optical positioning of the air holes in the shoe mold. After confirming the placement position, a tungsten carbide tip passes through the clearance groove and abuts against the air hole to complete the precise mechanical positioning. This dual verification method of optical and mechanical means effectively reduces the errors that may arise from a single positioning method, ensuring the accuracy and reliability of air hole positioning and providing a high-quality foundation for subsequent processing.

[0017] 2. This utility model features a detachable brush roller.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] Example 1

[0028] Please see Figures 1-5 This utility model provides a technical solution: a shoe mold air hole positioning device for positioning the air holes of a shoe mold 2, including a support frame 1, an mounting frame 31 on the support frame 1, a connecting frame 32 in the mounting frame 31, and a sliding ball 34 movably disposed in the connecting frame 32 for moving the shoe mold 2. The sliding ball 34 reduces the friction between the shoe mold 2 and the connecting frame 32 through rolling contact, facilitating quick adjustment of the position of the shoe mold 2 and avoiding surface scratches.

[0029] An infrared generator 58 is installed on the support frame 1 to locate the air holes on the shoe mold 2. The infrared generator 58 quickly marks the theoretical position of the air holes by emitting visible light spots, providing an initial positioning reference for subsequent mechanical positioning.

[0030] Furthermore, the support frame 1 has a placement groove for mounting the mounting frame 31, and the connecting frame 32 has several mounting grooves 33, each with a sliding ball bearing 34 movably disposed therein. The placement groove structure ensures the stable fitting of the mounting frame 31, and the array distribution of the mounting grooves 33 allows the sliding ball bearing 34 to evenly bear the weight of the shoe mold 2, improving the stability of movement.

[0031] Furthermore, an XY-axis feed stage 41 is provided at the bottom of the mounting frame 31. The output end of the XY-axis feed stage 41 is connected to a connecting seat 42, and a cylinder 43 is embedded in the connecting seat 42. The output end of the cylinder 43 is fixed with a tungsten steel tip 44 for positioning the air holes on the shoe mold 2. The XY-axis feed stage 41 realizes two-dimensional planar fine adjustment, and the cylinder 43 drives the tungsten steel tip 44 to move vertically. The combination of the two can accurately correct the infrared positioning deviation and ensure that the tungsten steel tip 44 is completely aligned with the center of the air hole.

[0032] Furthermore, the connecting frame 32 is provided with several clearance grooves 45. When the tungsten carbide tip 44 moves upward and passes through the clearance groove 45, it comes into contact with the air hole on the shoe mold 2. The clearance groove 45 provides a movement channel for the tungsten carbide tip 44, avoiding interference with the positioning action of the connecting frame 32 body and ensuring unobstructed mechanical positioning process.

[0033] Furthermore, a support base 51 is provided in the support frame 1, and a drive motor 52 is provided on the support base 51. The output shaft of the drive motor 52 is connected to a threaded rod 53 via a coupling. A movable seat 55 is externally threaded onto the threaded rod 53. A lifting frame 56 is fixed to the top of the movable seat 55, and a guide rail plate 57 is provided at the top of the lifting frame 56. An infrared generator 58 is movably mounted outside the guide rail plate 57. The drive motor 52 drives the movable seat 55 to move linearly via the threaded rod 53. The guide rail plate 57 allows for fine adjustment of the position of the infrared generator 58, achieving precise alignment of the infrared light spot with the air hole of the shoe mold 2.

[0034] Furthermore, a limit rod 54 is provided in the support frame 1, and a through hole is provided in the movable seat 55 for the limit rod 54 to pass through. The limit rod 54 and the through hole of the movable seat 55 constitute an anti-rotation structure, ensuring that the movable seat 55 moves only along the axial direction of the threaded rod 53, and preventing the lifting frame 56 from swaying and affecting the infrared positioning accuracy.

[0035] Example 2

[0036] Please see Figure 6 Furthermore, in conjunction with Embodiment 1, it is further found that the top of the support frame 1 is fixed with two sets of mounting brackets 61, each set of mounting brackets 61 is fixed with a guide rod 62, and a movable frame 63 is slidably arranged outside the two guide rods 62. A detachable brush roller 64 is rotatably arranged in the movable frame 63. A handle 65 is fixed to the top of the movable frame 63.

[0037] When the movable frame 63 slides outside the guide rod 62, the brush roller 64 abuts against the top of the support frame 1. During the sliding process, the brush roller 64 can remove debris from the surface of the support frame 1 and keep the device clean; its detachable design facilitates the periodic replacement or replenishment of lubricant, and indirectly lubricates the sliding ball 34 through rolling contact, reducing wear and maintaining the long-term flexibility of the sliding ball 34.

[0038] The working process of the shoe mold air hole positioning device is as follows:

[0039] The operator places the shoe mold 2 to be processed in the connecting frame 32 area at the top of the support frame 1. The bottom of the shoe mold 2 is adjusted horizontally by sliding balls 34 that are movable in multiple mounting slots 33 within the connecting frame 32. Infrared positioning calibration is then performed: the drive motor 52, fixed inside the support frame 1 by the support base 51, is started. Its output shaft drives the threaded rod 53 to rotate via a coupling. The movable seat 55, connected to the external thread of the threaded rod 53, moves axially under the guidance of the limit rod 54, causing the lifting frame 56 fixed at the top to move synchronously. The infrared generator 58, movable on the guide rail plate 57 at the top of the lifting frame 56, moves to a preset position. Infrared light is used to initially locate the air holes on the surface of the shoe mold 2. After confirming the placement of the infrared generator 58, optical positioning is completed.

[0040] After optical positioning is completed, mechanical positioning is performed: the XY-axis feed stage 41 at the bottom of the mounting frame 31 drives the connecting seat 42 to perform two-dimensional planar displacement, which in turn moves the cylinder 43 embedded in the connecting seat 42 to the target position. The output end of the cylinder 43 pushes the tungsten steel tip 44 upward. After the tungsten steel tip 44 passes through the clearance groove 45 opened in the connecting frame 32, it forms an abutment with the air hole on the bottom surface of the shoe mold 2, completing the precise positioning of the air hole, and then related work is carried out.

[0041] In addition, cleaning and lubrication maintenance can be performed: the operator manually pushes the movable frame 63 along the guide rods 62 fixed to the two sets of mounting brackets 61 at the top of the support frame 1. The detachable brush roller 64 rotating in the movable frame 63 abuts against the top of the support frame 1 during movement. The brush roller 64 is controlled by the handle 65 to clean the working area of ​​the device, removing residual debris or dust. Simultaneously, lubricant can be added inside or to the surface of the brush roller 64, which is released during rolling to properly lubricate the sliding balls 34 movable within the connecting frame 32, ensuring the flexibility and service life of the sliding balls 34. The entire workflow, through the coordinated verification of optical positioning and mechanical positioning, combined with cleaning and lubrication functions, achieves efficient and precise positioning of the shoe mold air holes and device maintenance.
