Description

Technical Field

[0001] This utility model relates to the field of mold positioning technology, specifically a positioning device applied to high-precision self-calibrating molds. Background Technology

[0002] In the field of mold processing, mold positioning and clamping are crucial for ensuring processing accuracy and efficiency. Traditional mold positioning methods typically employ mechanical or magnetic clamping, but these methods often suffer from low positioning accuracy, difficulty in controlling clamping force, and complex operation. With the development of modern manufacturing, the demands for precision and efficiency in mold processing are increasing, making traditional mold positioning methods insufficient for practical needs. To address these issues, researchers both domestically and internationally are continuously exploring new mold positioning technologies. Among these, high-precision self-calibrating mold positioning devices, as a novel mold positioning technology, have attracted considerable attention due to their advantages such as high positioning accuracy, controllable clamping force, and ease of operation. These devices typically achieve precise mold positioning and clamping through a series of sophisticated mechanical structures and sensors.

[0003] However, existing high-precision self-calibrating mold positioning devices still have some problems in their design and application. For example, the positioning accuracy and stability of some devices need to be improved; the operation process of some devices is too complicated, making it difficult for technicians to quickly learn; and the structure of some devices is too large or complex, making it difficult to quickly replace and maintain them on the production line.

[0004] Therefore, a positioning device for high-precision self-calibrating molds is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning device for high-precision self-calibrating molds. It can precisely adjust the position of the mold by moving the positioning plate and clamp the mold by using the reset action of the spring. At the same time, the setting of scale bars and indicator marks allows technicians to intuitively read and set the precise position of the mold, thereby greatly improving the positioning accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for a high-precision self-calibrating mold, comprising a mounting base plate, a mold mounted on the upper end of the mounting base plate, a groove carved on the upper end of the mounting base plate, slide rods fixedly connected to the four mutually distant inner walls of the groove, a movable ring sleeved on the outer end of the slide rod, a positioning plate fixedly connected to the upper end of the movable ring, a spring fixedly connected between the movable ring and the inner wall of the groove, the spring being located outside the slide rod, a fixing plate fixedly connected to the outer end of the positioning plate, a screw threadedly connected to the fixing plate, a pressure plate rotatably connected to the bottom end of the screw, and a rubber sleeve fixedly connected to the bottom end of the pressure plate. The mounting base plate has four evenly distributed positioning grooves carved on its upper end. These positioning grooves are located outside the slide groove. Multiple evenly distributed teeth are fixedly connected to the bottom of each positioning groove. An indicator mark is fixedly connected to the end of the positioning plate away from the fixed plate. Four evenly distributed scale bars are fixedly connected to the upper end of the mounting base plate. The indicator mark is located above the scale bars. This allows for precise adjustment of the mold's position by moving the positioning plate, and the mold is clamped using the spring's reset action. Furthermore, the scale bars and indicator marks enable technicians to intuitively read and set the mold's precise position, thus greatly improving positioning accuracy.

[0007] Preferably, the outer end of the slide rod is threaded with a limiting nut. By setting the limiting nut, the movable ring can slide continuously on the slide rod without easily separating from it.

[0008] Preferably, two mutually symmetrical auxiliary blocks are fixedly connected to the outer end of the movable ring. The auxiliary blocks are located in the slide groove and are in contact with the inner wall of the slide groove. A polished layer is provided at the contact points between the auxiliary blocks and the slide groove. By setting the auxiliary blocks, the movable ring is less likely to rotate when sliding along the slide rod, thereby improving the stability of the positioning plate when it moves.

[0009] Preferably, a handle is fixedly connected to the outer end of the positioning plate, and a finger groove is carved into the inner wall of the handle. By setting the handle, technicians can easily move the positioning plate, thereby improving the work efficiency of technicians.

[0010] Preferably, the spring is made of stainless steel and the surface of the spring is coated with anti-rust paint. By using stainless steel to make the spring and coating its surface with anti-slip texture, the spring is less likely to be damaged during long-term use, thereby improving the service life of the spring.

[0011] Preferably, a limiting ring is fixedly connected to the outer end of the fixed plate, and a limiting rod is fixedly connected to the upper end of the pressure plate. The limiting rod is located inside the limiting ring and is slidably connected to the limiting ring. By setting the limiting rod, it is possible to prevent the screw from easily driving the pressure plate to rotate when the technician rotates the screw, so that the pressure plate can be smoothly inserted into the positioning groove.

[0012] Preferably, a hand gripping block is fixedly connected to the upper end of the screw. The surface of the hand gripping block is engraved with anti-slip texture. By setting the hand gripping block, technicians can easily rotate the screw. By setting the anti-slip texture, technicians are less likely to slip when rotating the screw.

[0013] Compared with the prior art, this utility model provides a positioning device for high-precision self-calibrating molds, which has the following beneficial effects:

[0014] 1. This device, through the ingenious cooperation of components such as slide rails, slide rods, movable rings, positioning plates, and springs, forms a clamping mechanism that can move flexibly along the slide rails. Technicians can precisely adjust the position of the mold by moving the positioning plate according to the size of the mold, and achieve clamping of the mold with the help of the spring's reset action. At the same time, the setting of scale bars and indicator marks allows technicians to intuitively read and set the precise position of the mold, thereby greatly improving the positioning accuracy.

[0015] 2. The device features a combination of a fixing plate and a screw at the outer end of the positioning plate, providing a reliable solution for mold locking. The screw is threaded into the fixing plate, and its bottom end is rotatably connected to a pressure plate and a rubber sheath. This allows the screw to move downwards as it rotates until the rubber sheath tightly adheres to and engages with the positioning groove on the mounting base plate, simultaneously pressing against the teeth within the positioning groove. This locking mechanism is not only stable and reliable but also effectively prevents the mold from moving or shifting during processing, thus ensuring the accuracy and stability of mold processing.

[0016] 3. The device is equipped with components such as a limit nut, auxiliary block, handle, limit ring, and hand gripping block. The addition of these components greatly simplifies the operation process and improves work efficiency. For example, the limit nut makes it difficult for the movable ring to separate from the slide rod, ensuring the integrity of the clamping mechanism; the auxiliary block and polished layer reduce friction during sliding, improving the stability of the positioning plate during movement; the handle facilitates the movement of the positioning plate by technicians; the limit ring and limit rod prevent the screw from driving the pressure plate to rotate during rotation, thus ensuring that the pressure plate can be smoothly engaged in the positioning groove. In addition, the spring is made of stainless steel and coated with anti-rust paint, improving its service life and durability.

[0017] 4. The device is designed to be widely applicable and can be used for molds of different sizes and shapes. By adjusting the position of the positioning plate and the clamping force, it can achieve precise positioning and clamping of different molds. At the same time, due to its compact structure and ease of disassembly and cleaning, it is also convenient for quick replacement and maintenance on the production line. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1 - Figure 4 The positioning device for a high-precision self-calibrating mold in this embodiment includes a mounting base plate 1. A mold 2 is mounted on the upper end of the mounting base plate 1. A groove 3 is chiseled on the upper end of the mounting base plate 1. Each of the four mutually spaced inner walls of the groove 3 is fixedly connected to a slide rod 4. A movable ring 5 is sleeved on the outer end of the slide rod 4. A positioning plate 6 is fixedly connected to the upper end of the movable ring 5. A spring 7 is fixedly connected between the movable ring 5 and the inner wall of the groove 3. The spring 7 is located outside the slide rod 4. A fixing plate 8 is fixedly connected to the outer end of the positioning plate 6. The fixing plate 8 is internally threaded. A screw 9 is connected, and a pressure plate 10 is rotatably connected to the bottom end of the screw 9. A rubber coating 11 is fixedly connected to the bottom end of the pressure plate 10. Four evenly distributed positioning grooves 12 are chiseled on the upper end of the mounting base plate 1. The positioning grooves 12 are located outside the slide groove 3. Multiple evenly distributed teeth 13 are fixedly connected to the bottom end of the positioning grooves 12. An indicator mark 14 is fixedly connected to the end of the positioning plate 6 away from the fixed plate 8. Four evenly distributed scale bars 15 are fixedly connected to the upper end of the mounting base plate 1. The indicator mark 14 is located on the upper side of the scale bars 15.

[0027] Based on the mounting base plate 1, the upper end of which not only supports the mold 2, but also has a groove 3. The four sides of the groove 3 are fixedly connected to the sliding rods 4. These sliding rods not only serve as sliding tracks, but are also connected to the positioning plate 6 through the movable rings 5 ​​sleeved on their outer ends, forming a clamping mechanism that can move flexibly along the groove. The spring 7 added between the movable ring 5 and the inner wall of the groove 3 is located on the outside of the sliding rods 4, ensuring that when the positioning plate 6 is pushed outward by external force, it can automatically return under the reset action of the spring, thereby achieving the clamping effect on the mold.

[0028] The combination of the fixing plate 8 and the screw 9 added to the outer end of the positioning plate 6 provides a reliable solution for locking the mold. The screw is threaded into the fixing plate, and the pressure plate 10 and rubber sheath 11 rotatably connected to its bottom end can move downwards when the screw rotates until the rubber sheath fits tightly into the positioning groove 12 on the mounting base plate, while pressing the teeth 13 in the positioning groove, thereby achieving precise locking of the mold position. The ingenious cooperation of this series of structures and components not only achieves high-precision positioning of the mold, but also ensures the stability of the mold during processing through the reset action of the spring and the locking mechanism of the screw, greatly improving the accuracy and efficiency of mold processing.

[0029] Please see Figure 2 and Figure 4 The outer end of the slide rod 4 is threaded with a limit nut 401. By setting the limit nut 401, the movable ring 5 can slide continuously on the slide rod 4 without easily separating from the slide rod 4. The outer end of the movable ring 5 is fixedly connected with two mutually symmetrical auxiliary blocks 501. The auxiliary blocks 501 are located in the slide groove 3 and are in contact with the inner wall of the slide groove 3. The contact points between the auxiliary blocks 501 and the slide groove 3 are provided with a polished layer. By setting the auxiliary blocks 501, the movable ring 5 is not easy to rotate when sliding along the slide rod 4, thereby improving the stability of the positioning plate 6 when moving.

[0030] Please see Figure 3 and Figure 4 The outer end of the positioning plate 6 is fixedly connected to a handle 601. The inner wall of the handle 601 is chiseled with finger grooves. By setting the handle 601, technicians can easily move the positioning plate 6, thereby improving the work efficiency of technicians. The spring 7 is made of stainless steel and the surface of the spring 7 is coated with anti-rust paint. By using stainless steel to make the spring 7 and coating its surface with anti-slip texture, the spring 7 is not easily damaged during long-term use, thereby improving the service life of the spring 7.

[0031] Please see Figure 4A limiting ring 801 is fixedly connected to the outer end of the fixed plate 8, and a limiting rod 1001 is fixedly connected to the upper end of the pressure plate 10. The limiting rod 1001 is located inside the limiting ring 801 and is slidably connected to the limiting ring 801. By setting the limiting rod 1001, it is possible to prevent the screw 9 from driving the pressure plate 10 to rotate when the technician rotates the screw 9, so that the pressure plate 10 can be smoothly inserted into the positioning groove 12. A hand gripping block 901 is fixedly connected to the upper end of the screw 9. The surface of the hand gripping block 901 is engraved with anti-slip texture. By setting the hand gripping block 901, it is possible to make it easy for the technician to rotate the screw 9, and by setting the anti-slip texture, it is possible to prevent the technician from slipping when rotating the screw 9.

[0032] The working principle of the above embodiments is as follows:

[0033] In use, the technician places the mold 2 on the mounting base plate 1. According to the size of the mold 2, the positioning plate 6 is moved outward so that the positioning plate 6 abuts against the side wall of the mold 2. With the reset action of the spring 7, the four positioning plates 6 clamp the mold 2. With the sliding action of the movable ring 5 and the slide rod 4, the technician can adjust the locking position of the mold 2 on the mounting base plate 1. The technician can also refer to the scale bar 15 and the indicator mark 14 to accurately set the position of the mold 2. After setting, the screw 9 is rotated so that the pressure plate 10 moves downward, thereby causing the rubber layer 11 at the bottom of the pressure plate 10 to engage in the positioning groove 12 and press the rubber layer 11 down to press against the teeth 13, thus locking the position of the mold 2. The position of the mold is accurately adjusted by moving the positioning plates, and the clamping of the mold is achieved with the reset action of the spring. At the same time, the setting of the scale bar and the indicator mark allows the technician to intuitively read and set the precise position of the mold, thereby greatly improving the positioning accuracy.

[0034] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0035] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
