[0002] In the field of automotive mold processing, high-precision and high-stability clamping and positioning are key to ensuring processing quality. Traditional mold fixing methods often involve manually adjusting the position of the clamps and rigidly locking them with bolts or pressure plates. Although this method is simple in structure, it has obvious drawbacks in practical applications.

[0003] For example, common manual screw clamping devices require operators to adjust the positions of the clamping blocks on both sides one by one according to the mold size, and then tighten the fixing bolts. This process relies on manual experience, is time-consuming, and it is difficult to ensure the symmetry and synchronization of the clamping positions on both sides. At the same time, the rigid pressure plate acts directly on the mold surface, which can easily cause local pressure damage or stress deformation for molds with high surface precision requirements, affecting the final accuracy and service life of the mold.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-4 In the first embodiment of this utility model, a support component 1 is provided, including a support column 101 and an operating table 102. The upper end of the support column 101 is fixedly connected to the lower end of the operating table 102. An adjustment mechanism 2 is provided at both ends of the operating table 102. A limit mechanism 3 is provided at both ends of the adjustment mechanism 2. The adjustment mechanism 2 is used to adjust the distance between the limit mechanisms 3. The limit mechanism 3 is used to limit and fix the automobile mold.

[0022] Specifically, the support component 1 provides a solid foundation for the entire mold clamping system through the stable connection between the bearing column 101 and the operating table 102, ensuring the structural rigidity and stability during the processing. The adjustment mechanism 2 and the limiting mechanism 3 set on the operating table 102 work together to solve the problems of poor adaptability to molds of different sizes, low adjustment efficiency, and inaccurate positioning in traditional clamping methods. By automatically adjusting the spacing of the limiting mechanism 3, it realizes rapid adaptation and reliable fixation of various specifications of automotive molds, improves clamping efficiency and positioning accuracy, and effectively prevents mold displacement or vibration during processing, providing a strong guarantee for achieving high-precision and high-efficiency mold processing.

[0023] Furthermore, in the preparation stage of the automobile mold processing, the mold to be processed must first be placed stably on the center area of ​​the upper surface of the operating table 102 to ensure that its position is basically centered, so as to provide a basis for subsequent clamping and positioning. Then, the adjustment mechanism 2 adjusts the distance between the limiting mechanism 3, and the limiting mechanism 3 limits and fixes the automobile mold.

[0024] Example 2 The second embodiment of this utility model provides an adjustment mechanism 2 including a fixed frame 201, a servo motor 202, a double-ended screw 203, a bearing seat 204, a transmission plate 205, and a guide groove 206. The inner wall of the fixed frame 201 is fixedly connected to the surface of the servo motor 202. The output end of the servo motor 202 is fixedly connected to the right end of the double-ended screw 203. The surface of the double-ended screw 203 is threadedly connected to the inner wall of the transmission plate 205. The surface of the double-ended screw 203 is rotatably connected to the inner wall of the bearing seat 204. The guide groove 206 is opened on both sides of the upper end of the operating table 102. The surface of the fixed frame 201 is fixedly connected to the right end of the operating table 102. The two ends of the double-ended screw 203 are rotatably connected to the inner wall of the operating table 102. The surface of the bearing seat 204 is fixedly connected to the inner wall of the operating table 102. The surface of the transmission plate 205 is slidably connected to the inner wall of the guide groove 206. The lower end of the transmission plate 205 is slidably connected to the inner wall of the operating table 102 through a sliding groove.

[0025] Specifically, the adjustment mechanism 2 drives the double-headed screw 203 to rotate via the servo motor 202. The screws with opposite directions at both ends synchronously drive the two transmission plates 205 to move towards or away from each other within the guide groove 206, achieving precise and synchronous adjustment of the spacing between the transmission plates 205. This structure effectively solves the problems of low efficiency, poor synchronization, and insufficient positioning accuracy of traditional manual adjustment. It can quickly adapt to the clamping requirements of molds with different widths. In conjunction with the guide groove 206 and the sliding connection structure, it ensures the smoothness and repeatability of the movement of the transmission plates 205, laying the foundation for the accurate alignment and reliable clamping of the subsequent limiting mechanism 3, and improving the adaptability of mold clamping.

[0026] Furthermore, a servo motor 202 is installed at each end of the operating table 102, and its output shaft is connected to a double-ended screw 203. The two ends of the double-ended screw 203 are machined with threads of opposite directions, i.e., one end is left-handed and the other end is right-handed. When the servo motor 202 is started, it drives the double-ended screw 203 to rotate synchronously. Since the threads are of opposite directions, the two transmission plates 205 installed on the screw will move towards or in opposite directions along the guide grooves 206 pre-cut on the operating table 102 under the drive of the screw, thereby realizing the movement between the transmission plates 205. The relative position is adjusted as the transmission plates 205 at both ends move, and the transmission rod fixed at the upper end of them also moves accordingly, thereby driving the limiting mechanism 3 located at the top of the transmission rod to move synchronously. By controlling the rotation angle and direction of the two servo motors 202, the lateral distance between the limiting mechanisms 3 on both sides of the operating table 102 can be flexibly adjusted. This adjustment process needs to be set according to the specific external dimensions and structural characteristics of the mold to be processed, to ensure that the limiting mechanisms 3 on both sides can be accurately aligned with the predetermined clamping area of ​​the mold, providing reliable support for subsequent precise positioning and clamping.

[0027] Example 3 The third embodiment of this utility model provides a limiting mechanism 3 including a fixed sleeve 301, a connecting rod 302, a mounting plate 303, a cam 304, a flexible plate 305, and a stepper motor 306. The inner wall of the fixed sleeve 301 is fixedly connected to the surface of the connecting rod 302. The two ends of the connecting rod 302 are fixedly connected to the inner wall of the mounting plate 303. The inner wall of the mounting plate 303 is rotatably connected to the inner wall of the cam 304. The surface of the cam 304 is fixedly connected to the surface of the flexible plate 305. The inner wall of the cam 304 is fixedly connected to the output end of the stepper motor 306. The surface of the mounting plate 303 is fixedly connected to the surface of the stepper motor 306. The lower surface of the mounting plate 303 is slidably connected to the upper surface of the operating table 102. The upper end of the transmission plate 205 is fixedly connected to the surface of the fixed sleeve 301.

[0028] Specifically, the limiting mechanism 3 precisely drives the cam 304 to rotate via the stepper motor 306, which in turn drives the flexible plate 305 to rotate and press down, thereby achieving flexible clamping of the four corners of the mold. Compared with traditional clamping methods, the flexible plate 305 can effectively fit the slight unevenness of the mold surface, avoiding deformation or damage caused by stress concentration, while ensuring uniform distribution of clamping force. This structure solves the problem of displacement, vibration or surface damage caused by improper clamping of the mold, and improves the reliability and safety of clamping.

[0029] Furthermore, after the lateral position adjustment of the limiting mechanism 3 is completed, the stepper motor 306 installed on the upper end of the transmission plate 205 can be started. The output shaft of the stepper motor 306 is connected to the cam 304 mechanism. When the motor runs, it drives the cam 304 to rotate continuously. The non-circular contour of the cam 304 drives the flexible plate 305 on its surface to rotate during the rotation. As the cam 304 rotates, the flexible plate 305 gradually rotates and contacts the four corner areas of the mold. The deformation ability of the flexible material is used to adapt to the slight unevenness of the mold edge, so as to achieve uniform fit and flexible clamping. When the flexible plates 305 at the four corners are in stable contact with the mold surface and an appropriate pre-tightening force is applied, the mold as a whole is firmly limited, thereby ensuring that it remains stable during subsequent cutting, milling and other processing, preventing displacement or vibration, and providing necessary process protection for processing.

[0030] Working principle: In the preparation stage of automobile mold processing, the mold to be processed must first be placed stably on the center area of ​​the upper surface of the operating table 102 to ensure that its position is basically centered, providing a basis for subsequent clamping and positioning. A servo motor 202 is installed at each end of the operating table 102, and its output shaft is connected to a double-ended screw 203. The two ends of the double-ended screw 203 are machined with threads of opposite directions, i.e., one end is left-handed and the other end is right-handed. When the servo motor 202 starts, it drives the double-ended screw 203 to rotate synchronously. With opposite rotation directions, the two transmission plates 205 mounted on the screw will move towards or away from each other along the guide grooves 206 pre-cut on the operating table 102 under the drive of the screw, thereby adjusting the relative position between the transmission plates 205. As the transmission plates 205 at both ends move, the transmission rods fixed at their upper ends also move, thereby driving the limiting mechanism 3 located at the top of the transmission rod to perform synchronous displacement. By controlling the rotation angle and direction of the two servo motors 202, the horizontal distance between the limiting mechanisms 3 on both sides of the operating table 102 can be flexibly adjusted. The adjustment process needs to be set according to the specific external dimensions and structural characteristics of the mold to be processed, to ensure that the limiting mechanisms 3 on both sides can be accurately aligned with the predetermined clamping area of ​​the mold, providing reliable support for subsequent precise positioning and clamping. After the lateral position adjustment of the limiting mechanism 3 is completed, the stepper motor 306 installed on the upper end of the transmission plate 205 can be started. The output shaft of the stepper motor 306 is connected to the cam 304 mechanism. When the motor runs, it drives the cam 304 to rotate continuously. The non-circular contour of the cam 304 drives the flexible plate 305 on its surface to rotate during the rotation. As the cam 304 rotates, the flexible plate 305 gradually rotates and contacts the four corner areas of the mold. The deformation ability of the flexible material is used to adapt to the slight unevenness of the mold edge, so as to achieve uniform fit and flexible clamping. When the flexible plates 305 at the four corners are in stable contact with the mold surface and an appropriate pre-tightening force is applied, the mold is firmly limited, thereby ensuring its stability during subsequent cutting, milling and other processing, preventing displacement or vibration, and providing necessary process guarantee for processing.

[0031] In summary, the coordinated operation of the servo motor-driven double-headed screw, transmission plate, and limiting mechanism enables rapid lateral positioning and initial clamping of molds of different sizes. Combined with the linkage effect of the stepper motor-driven cam pushing the flexible plate, adaptive clamping of the four corners of the mold is finally achieved, effectively improving the accuracy, stability, and adaptability of mold clamping and providing a reliable positioning basis for subsequent processing.

[0032] In summary, the coordinated operation of the servo motor-driven double-headed screw, transmission plate, and limiting mechanism enables rapid lateral positioning and initial clamping of molds of different sizes. Combined with the linkage effect of the stepper motor-driven cam pushing the flexible plate, adaptive fixing of the four corners of the mold is ultimately achieved. The entire mechanism, through the combination of mechanical linkage and step-by-step control, effectively improves the accuracy, stability, and adaptability of mold clamping, providing a reliable positioning foundation for subsequent high-precision machining.
