Description

Technical Field

[0001] This utility model relates to the field of mold inspection technology, specifically to an adaptive clamping mechanism for mold processing. Background Technology

[0002] Molds are core tools in the product manufacturing process, and their quality directly determines the product's quality and lifespan. Therefore, accurate mold testing is crucial. During mold testing, stable mold fixation and flexible adjustment of the testing equipment are key to ensuring testing accuracy, but existing technologies still have many limitations.

[0003] In some testing equipment, the mold's position is relatively fixed after it is fixed. If multiple positions or angles of the mold need to be tested, it is often necessary to frequently remove the mold from the fixed fixture and re-clamp it, which is cumbersome and prone to errors due to repeated clamping, affecting testing efficiency and accuracy. To solve this problem, adjustable angle positioning devices have emerged in related technologies. For example, Chinese Patent Publication No. CN223000407U discloses a positioning device for mold processing and testing, which achieves angle adjustment of the clamping plate through the cooperation of lifting and rotating components, theoretically changing the testing angle of the mold. However, this structure has obvious drawbacks in practical applications. Its rotating component needs to be lifted by the lifting component before it can engage and drive, making the operation complicated and unable to achieve rapid angle adjustment. Moreover, the clamping plates are mostly rigid structures, which are difficult to adapt to the dimensional differences of different sides for molds with rectangular sides of different lengths and lengths. This can easily lead to local over-clamping or loosening, causing the mold to shift during angle adjustment. In addition, when multiple clamping adjustments are required to detect different positions, the rigid clamping structure cannot accommodate the positional deviation of the mold and still requires manual calibration and clamping. This fails to fundamentally solve the problem of multiple clamping and limits the improvement of detection efficiency. Utility Model Content

[0004] To address the aforementioned issues, an adaptive clamping mechanism for mold processing is provided. Taking into account the inconsistent lengths of the mold's long and short sides, four equidistant first sliding grooves and sliders arranged around the base's centerline, along with synchronously driven connecting rods, enable uniform clamping from all sides of the mold, ensuring balanced force distribution. Furthermore, the mold does not require strict alignment with the positioning area during placement; even with positional deviations, the mechanism can adaptively adjust, improving adaptability to molds of different sizes and clamping stability.

[0005] To address the problems of existing technologies, this utility model provides an adaptive clamping mechanism for mold processing, including a base. A mold positioning area is provided at the top center of the base. The base has four first sliding grooves, which are equidistantly arranged around the center line of the base. Each first sliding groove has a slider that slides in cooperation with it, and the slider is elastically connected to the end of the first sliding groove. A connecting rod is provided on the slider and rotatedly connected to it. The base has a drive mechanism inside for simultaneously driving the connecting rods on the four sliders to rotate. When the end of the connecting rod contacts the edge of the mold, the slider can slide along the first sliding groove to compensate for the positional difference when the connecting rod contacts the edge of the mold.

[0006] Preferably, the connecting rod is provided with a drive shaft that is fixedly connected to it, the drive shaft is rotatably mounted on the slider, and the drive mechanism includes synchronous pulleys respectively sleeved on the bottom of each drive shaft and synchronous belts wound around all the synchronous pulleys.

[0007] Preferably, the base has a second sliding groove extending in the horizontal direction, and a mounting bracket is slidably connected to the second sliding groove. The mounting bracket is elastically connected to the end of the second sliding groove, and the mounting bracket is provided with a mounting wheel for tensioning the timing belt.

[0008] Preferably, the mounting bracket is also equipped with a rotary drive motor for driving the mounting wheels.

[0009] Preferably, each first slide groove is provided with a fixed rod at one end away from the center of the base, and an elastic telescopic rod is provided between the fixed rod and the slider, with the two ends of the elastic telescopic rod being hinged to the fixed rod and the slider respectively.

[0010] Preferably, a rotatable semi-circular abutment block is provided at the end of the connecting rod away from the slider.

[0011] The advantages of this utility model compared to the prior art are:

[0012] 1. This application utilizes four equidistant first sliding grooves and sliders arranged around the center line of the base, along with synchronously driven connecting rods, to achieve uniform clamping from all four sides of the mold, ensuring force balance. It also precisely adapts to the four sides of the mold, addressing the issue of inconsistent lengths between the long and short sides. The synergistic effect of the slider sliding and the elastic connection eliminates the need for strict alignment of the mold with the positioning area during placement; even with positional deviations, the mechanism can adaptively adjust, further enhancing operational convenience. The clamping force provided by the elastic connection ensures that the mold does not shift during processing and avoids mold damage caused by uneven force on the long and short sides, significantly improving adaptability to molds of different sizes and clamping stability.

[0013] 2. This application, through the cooperation of mounting wheels, a sliding mounting bracket, and elastic connections, can automatically adjust the tension of the synchronous belt, effectively avoiding transmission slippage or decreased synchronization caused by belt slack. This ensures the synchronous rotation accuracy of the four drive shafts and connecting rods, thereby guaranteeing the coordination of the clamping action on all four sides of the mold, especially suitable for precise clamping when the long and short sides of the mold are of different lengths. The sliding of the mounting bracket along the second horizontal groove and the deformation of the elastic connection can adapt to the slack of the synchronous belt under different working conditions, eliminating the need for manual adjustment and improving the automation level and ease of use of the mechanism.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 3 and Figure 7 As shown: An adaptive clamping mechanism for mold processing includes a base 1, a mold positioning area is provided at the top center of the base 1, and four first slide grooves 11 are provided on the base 1, which are equidistantly arranged around the center line of the base 1; each first slide groove 11 is provided with a slider 111 that slides and engages with it, and the slider 111 is elastically connected to the end of the first slide groove 11; a connecting rod 112 is provided on the slider 111 and rotates therewith; the base 1 is provided with a drive mechanism 12 for simultaneously driving the connecting rods 112 on the four sliders 111 to rotate. When the end of the connecting rod 112 contacts the edge of the mold 3, the slider 111 can slide along the first slide groove 11 to compensate for the positional difference when the connecting rod 112 contacts the edge of the mold 3.

[0024] In use, the mold 3 to be processed is placed in the mold positioning area at the center of the top of the base 1, without needing to be strictly aligned with the center position. At this time, the drive mechanism 12 inside the base 1 is activated. The drive mechanism 12 simultaneously drives the connecting rods 112 on the four sliders 111 to rotate synchronously, so that the ends of the connecting rods 112 gradually approach the edge of the mold 3. When the ends of the connecting rods 112 contact the edge of the mold 3, since the mold 3 is mostly rectangular, the lengths of the long and short sides of the mold 3 are not the same. The timing and position of the connecting rods 112 contacting the long and short sides will be different. When the end of the connecting rod 112 first contacts a certain side of the mold 3, the corresponding slider 111 will slide along the first slide groove 11. The sliding compensates for the contact position deviation caused by the length difference of the side length of the mold 3, ensuring that the connecting rods 112 that subsequently contact other sides can also be adapted to their respective sides by sliding the sliders 111. Even if there is a certain deviation in the placement position of the mold 3, the sliding of the sliders 111 can further compensate for the position error, and finally make the ends of the four connecting rods 112 fit tightly with the four sides of the mold 3 respectively. Meanwhile, the elastic connection between the slider 111 and the end of the first groove 11 will deform due to the sliding of the slider 111, and apply a continuous and balanced clamping force to the four sides through elastic force. This force can be adaptively adjusted according to the length difference between the long side and the short side to ensure stable clamping of the mold 3.

[0025] The first slide groove 11 and the slider 111, arranged equidistantly around the center line of the base 1, together with the synchronously driven connecting rod 112, can achieve uniform clamping from all four sides of the mold 3, ensuring the force balance of the mold 3. At the same time, it can achieve precise adaptation to the four sides of the mold 3, taking into account the fact that the long side and the short side of the mold 3 are not the same length.

[0026] Meanwhile, the synergistic effect of the sliding block 111 and the elastic connection allows the mold 3 to be placed without strict alignment with the positioning area. Even if there is a positional deviation, the mechanism can adaptively adjust, further enhancing operational convenience. The clamping force provided by the elastic connection ensures that the mold 3 does not shift during processing and avoids damage to the mold 3 caused by uneven force on the long and short sides, significantly improving the adaptability to molds 3 of different sizes and clamping stability.

[0027] It should be noted that the clamping effect can be further optimized by adding auxiliary positioning methods such as fixing mechanism for connecting rod 112, which will not be elaborated here.

[0028] like Figures 1 to 6 As shown: A transmission shaft 1121 is fixedly connected to the connecting rod 112. The transmission shaft 1121 is rotatably mounted on the slider 111. The drive mechanism 12 includes a synchronous pulley 121 respectively sleeved on the bottom of each transmission shaft 1121 and a synchronous belt 122 wound around all the synchronous pulleys 121.

[0029] When the drive mechanism 12 is activated, power is transmitted through the synchronous belt 122 to the synchronous pulleys 121 at the bottom of each drive shaft 1121. The synchronous pulleys 121 rotate synchronously with the synchronous belt 122, thereby driving the drive shafts 1121 fixedly connected to them to rotate. The drive shafts 1121 then drive the connecting rods 112 fixed to them to rotate synchronously, causing the ends of the four connecting rods 112 to move towards the edge of the mold 3 simultaneously. Since the drive shafts 1121 are rotatably mounted on the slider 111, when the slider 111 slides along the first groove 11 to compensate for the difference in length or position of the mold 3, the drive shafts 1121 can move synchronously with the slider 111 while maintaining rotation. This ensures that the rotation of the connecting rods 112 and the sliding of the slider 111 do not interfere with each other, achieving coordinated operation of transmission and position compensation.

[0030] The synchronous pulley 121 and synchronous belt 122 work together to precisely achieve synchronous rotation of the four drive shafts 1121, thereby ensuring that the rotation rhythm of the four connecting rods 112 is completely consistent. This avoids any connecting rod 112 contacting the edge of the mold 3 prematurely or lagging behind due to asynchronous transmission, ensuring coordinated and unified clamping action on all four sides of the mold 3, especially suitable for the characteristic that the long and short sides of the mold 3 are not the same length. The transmission structure of synchronous belt 122 and synchronous pulley 121 is simple and compact, easy to install and maintain, and can reduce the complexity of the mechanism while ensuring transmission accuracy, further enhancing the adaptive clamping effect on molds 3 of different sizes.

[0031] like Figures 1 to 4As shown: A second sliding groove 124 extending horizontally is provided on the base 1. A mounting bracket 123 is slidably connected to the second sliding groove 124. The mounting bracket 123 is elastically connected to the end of the second sliding groove 124. A mounting wheel 1231 for tensioning the synchronous belt 122 is provided on the mounting bracket 123.

[0032] When the synchronous belt 122 experiences slack due to the sliding of the slider 111 during transmission, the elastic connection between the mounting bracket 123 and the end of the second slide groove 124 generates an elastic force, pushing the mounting bracket 123 to slide along the horizontally extending second slide groove 124. This, in turn, causes the mounting wheels 1231 mounted on the mounting bracket 123 to move synchronously, applying a continuous tension force to the synchronous belt 122 and ensuring that the synchronous belt 122 always maintains a tight fit with each synchronous wheel 121. Simultaneously, the mounting wheels 1231 are rotatably mounted on the mounting bracket 123, allowing them to move and adjust their position with the mounting bracket 123 while also rotating flexibly with the transmission of the synchronous belt 122. This avoids obstructing the normal transmission of the synchronous belt 122, achieving coordinated operation of the tensioning and transmission functions.

[0033] Through the cooperation of the mounting wheel 1231, the sliding mounting bracket 123, and the elastic connection, the tension of the synchronous belt 122 can be automatically adjusted, effectively avoiding transmission slippage or decreased synchronization caused by the slack of the synchronous belt 122. This ensures the synchronous rotation accuracy of the four transmission shafts 1121 and the connecting rod 112, thereby guaranteeing the coordination of the clamping action on all four sides of the mold 3, especially suitable for the precise clamping requirements when the long and short sides of the mold 3 are of different lengths. The sliding of the mounting bracket 123 along the horizontal second slide groove 124 and the deformation of the elastic connection can adapt to the slack of the synchronous belt 122 under different working conditions, eliminating the need for manual adjustment and improving the automation level and ease of use of the mechanism. At the same time, this tensioning structure is simple and reliable, reducing clamping errors caused by unstable transmission of the synchronous belt 122, and further enhancing the overall mechanism's adaptive clamping stability and reliability for molds 3 of different sizes.

[0034] like Figures 3 to 6 As shown: The mounting bracket 123 is also equipped with a rotary drive motor 1232 for driving the mounting wheels 1231.

[0035] A rotary drive motor 1232 is mounted on a mounting bracket 123, directly driving the mounting wheel 1231 to rotate. During rotation, the mounting wheel 1231 drives the synchronous belt 122 through friction with it, thereby driving the synchronous pulleys 121 at the bottom of each transmission shaft 1121 to rotate synchronously. Simultaneously, the sliding of the mounting bracket 123 along the second groove 124 and its elastic connection to the end of the second groove 124 ensure that the mounting wheel 1231 applies appropriate tension to the synchronous belt 122 while driving it, keeping the synchronous belt 122 in close contact with each synchronous pulley 121 and preventing slippage or misalignment during transmission.

[0036] The rotary drive motor 1232 provides active driving force to the mounting wheel 1231, directly driving the synchronous belt 122. This enhances the power output and stability of the synchronous belt 122 transmission, especially when clamping molds 3 of different sizes. Stable power transmission ensures the synchronous rotation of the four connecting rods 112, precisely adapting to the length differences between the long and short sides of the mold 3. The combination of active drive and tensioning functions ensures the tension of the synchronous belt 122 and improves transmission efficiency, avoiding potential power shortages or lag issues caused by passive transmission. This further guarantees the coordination and consistency of the clamping action on all four sides of the mold 3. Simultaneously, this structure makes the power source of the transmission system more direct, reducing transmission losses and enhancing the reliability of the mechanism in long-term use, better meeting the adaptive clamping requirements of different molds 3.

[0037] like Figures 3 to 6 As shown: Each first slide groove 11 is provided with a fixed rod 113 at one end away from the center of the base 1. An elastic telescopic rod 1131 is provided between the fixed rod 113 and the slider 111. The two ends of the elastic telescopic rod 1131 are respectively hinged to the fixed rod 113 and the slider 111.

[0038] When the slider 111 slides along the first groove 11, since the two ends of the elastic telescopic rod 1131 are hinged to the fixed rod 113 and the slider 111 respectively, the elastic telescopic rod 1131 can flexibly extend and retract with the sliding of the slider 111. At the same time, the hinge structure adapts to the angle change of the slider 111 during the sliding process, maintaining a stable connection with the fixed rod 113 and the slider 111. When the end of the connecting rod 112 contacts the edge of the mold 3, and the slider 111 slides along the first groove 11 due to the difference between the long and short sides of the mold 3 or the positional deviation, the elastic telescopic rod 1131 will extend or shorten accordingly, generating elastic force through its own deformation. This elastic force acts on the slider 111, pushing the slider 111 to keep the connecting rod 112 in contact with the edge of the mold 3, thereby providing a continuous clamping force for the mold 3.

[0039] As an elastic element, the elastic telescopic rod 1131 can transmit elastic force more stably compared to other elastic structures. Its hinged ends allow for flexible angle adjustment as the slider 111 slides, preventing jamming or damage caused by torque generated by the slider 111's movement and ensuring reliable elastic compensation. The fixed rod 113 is located at the end of the first slide groove 11 furthest from the center of the base 1, providing a stable mounting base for the elastic telescopic rod 1131 and enhancing the overall stability of the elastic connection structure. For the mold 3, the difference in length between the long and short sides results in different sliding distances for the corresponding slider 111. The telescopic amount of the elastic telescopic rod 1131 can adapt to this difference, providing a balanced clamping force through varying degrees of deformation, ensuring consistent clamping effect on all four sides of the mold 3, further improving the mechanism's adaptability and clamping reliability for molds 3 of different sizes.

[0040] like Figure 2 and Figure 7 As shown: A rotatable semi-circular abutment block 1122 is provided at the end of the connecting rod 112 away from the slider 111.

[0041] When the connecting rod 112 approaches the edge of the mold 3 under the drive of the drive mechanism 12, the semi-circular abutment block 1122 at the end of the connecting rod 112 first contacts the edge of the mold 3. Since the abutment block 1122 can rotate, it can automatically adjust its rotation angle according to the angle of the edge of the mold 3 at the moment of contact, so that the semi-circular arc surface or plane fits the edge of the mold 3. As the slider 111 slides along the first slide groove 11 to compensate for the position difference, the abutment block 1122 will continue to rotate to adapt to the contour change of the edge of the mold 3, always maintaining close contact with the edge of the mold 3. With the force of the elastic telescopic rod 1131, stable clamping of the edge of the mold 3 is achieved.

[0042] The semi-circular abutment block 1122's shape increases the contact area with the edge of the mold 3, reducing local pressure and preventing damage to the mold 3's edge. Simultaneously, its curved structure can accommodate any chamfers or minor protrusions on the mold 3's edge, improving the fit of the contact. The rotatable nature of the abutment block 1122 adapts to different contact angles formed between the connecting rod 112 and the edge of the mold 3 during rotation and sliding of the slider 111. Whether it's the long or short side of the mold 3, rotation can adjust to the optimal contact posture, preventing instability or slippage due to angle deviations. This further enhances the mechanism's adaptability to the mold 3, especially when there are differences in the mold 3's dimensions. Adaptive adjustment of the contact angle and area ensures balanced clamping force on all four sides, improving overall clamping stability and reliability.

[0043] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the appended claims.
