Technical Field

[0001] This utility model relates to the field of robotic arm manufacturing technology, and in particular to a locking device for a robotic arm mold. Background Technology

[0002] In existing robotic arm manufacturing processes, two molds are typically joined together to press and solidify the robotic arm component placed between them. However, this traditional mold-joining method has significant drawbacks. First, the positioning between the molds relies mainly on simple guide pillars and sleeves or manual alignment, resulting in poor positioning capabilities and a tendency for misalignment or displacement. This affects the mold-joining accuracy, leading to low dimensional consistency and unstable quality in the finished robotic arm. Second, it is difficult to effectively control and maintain the mold-joining pressure during the process. Uneven pressure distribution or fluctuations in pressure values ​​can further cause internal structural defects in the product, such as air bubbles, insufficient adhesive, or substandard mechanical properties.

[0003] The aforementioned problems severely restrict the mass production quality and efficiency of robotic arms. Existing technologies lack a mold-closing mechanism that can effectively guarantee centering accuracy and pressure stability.

[0004] In summary, the existing robotic arm mold-closing mechanisms suffer from poor centering accuracy and uneven pressure stability. Utility Model Content

[0005] This invention provides a locking device for a robot arm mold, which can solve the problems of poor centering accuracy and uneven pressure stability in the existing robot arm mold closing mechanism.

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0022] like Figures 1 to 6 As shown, the present invention provides a locking device for a robot arm mold 100, which is used for pressing the robot arm mold 100. The locking device for the robot arm mold includes a locking assembly 1, a locking frame 2, and a drive mechanism 5. The locking assembly 1 includes a sliding template 11 and a fixed template 12 arranged opposite to each other. An arm mold placement groove A 111 is provided on one side of the sliding template 11 near the fixed template 12. An arm mold placement groove B 121 is provided on the fixed template 12 at the position corresponding to the arm mold placement groove A 111. A mold cavity is formed between the arm mold placement groove A 111 and the arm mold placement groove B 121, which can be used to accommodate and form the robot arm mold 100. The robot arm mold is placed in the arm mold placement groove B. During the opening and closing action of the sliding template 11 relative to the fixed template 12, the mold is locked or released by moving the arm mold placement groove A 111 closer to or further away from the arm mold placement groove B 121. Mold locking frame 2, which includes mold locking frame body 3 and a first sliding track 4 disposed inside the mold locking frame body 3, and the sliding template 11 and the fixed template 12 are both sleeved on the outside of the first sliding track 4; The mold clamping frame body 3 is designed to be robust and durable, capable of withstanding the enormous pressure generated during mold clamping. The first sliding rail 4 ensures smooth sliding of the sliding template 11 and the fixed template 12 during mold clamping and release. This design not only improves the stability of the mold clamping device but also effectively extends its service life. The smooth movement of the sliding template 11 and the fixed template 12 on the first sliding rail 4 is key to achieving rapid and accurate mold clamping and release. The drive mechanism 5 drives the sliding template 11 to move along the first sliding track 4. This drive mechanism 5 can be a high-performance servo electric cylinder, hydraulic cylinder, or pneumatic cylinder, ensuring the accuracy and stability of the sliding template 11 during movement. The drive mechanism 5 drives the sliding template 11 to move linearly along the first sliding track 4. This design not only improves the working efficiency of the mold-locking device but also ensures the accuracy of mold locking and releasing. Furthermore, the drive mechanism 5 can also have overload protection, automatically stopping the machine in case of abnormal conditions, effectively preventing equipment damage and safety accidents.

[0023] like Figures 1 to 2As shown, in some embodiments of this utility model, in order to improve the accuracy and stability of the mold cavity, the first sliding track 4 is preferably made of a high-strength, wear-resistant material, such as hard alloy or hardened steel. Furthermore, the surfaces of the sliding template 11 and the fixed template 12 are also precision machined to ensure the smoothness and dimensional accuracy of the mold cavity.

[0024] like Figures 1 to 2 As shown, in some embodiments of this utility model, the locking mold frame body 3 includes a first mounting plate 31 and a second mounting plate 32, which are arranged in parallel. The upper and lower ends of the rear side of the first mounting plate 31 are respectively provided with a first connecting plate 33 and a second connecting plate 34. The end of the first connecting plate 33 away from the first mounting plate 31 and the end of the second connecting plate 34 away from the first mounting plate 31 are fixedly connected to the second mounting plate 32; that is, the first mounting plate 31, the second mounting plate 32, the first connecting plate 33 and the second connecting plate 34 are combined to form a rectangular frame structure. The fixed template 12 is set on the second mounting plate 32; The drive mechanism 5 is mounted on the first mounting plate 31; The two ends of the first sliding track 4 are respectively disposed on the first mounting plate 31 and the second mounting plate 32; specifically, there are four first sliding tracks 4, and the four first sliding tracks 4 are distributed in a rectangular shape. Specifically, the sliding template 11 has a through hole A 112 that matches the first sliding track 4, so that the sliding template 11 can move smoothly and accurately in a straight line along the first sliding track 4.

[0025] like Figures 1 to 2 As shown, in some embodiments of this utility model, the fixed template 12 is also provided with a through hole B 122 that cooperates with the first sliding track 4, and the fixed template 12 can be fixedly sleeved on the outside of the first sliding track 4; the fixed connection method can be a welding connection method.

[0026] like Figures 1 to 2 As shown, in some embodiments of this utility model, the fixed template 12 can be slidably sleeved on the outside of the first sliding track 4, and the fixed template 12 can be fixed to the front side of the second mounting plate 32 by bolt connection. When the fixed template 12 is slidably sleeved on the outside of the first sliding track 4 and fixed to the front side of the first mounting plate 31 by bolt connection, in order to facilitate the installation and disassembly of the bolts, bolt mounting holes are provided at corresponding positions on the front side of the first mounting plate 31. The shape and size of the bolt mounting holes are matched with the bolts used to ensure that the bolts can firmly connect the fixed template 12 and the second mounting plate 32. In addition, to enhance the stability of the fixed template 12 on the first sliding track 4, a wear-resistant bushing can be provided in the perforation B122 of the fixed template 12. The wear-resistant bushing is made of a high-strength, low-friction material, such as polytetrafluoroethylene or nylon, to reduce the wear of the fixed template 12 when sliding on the first sliding track 4, while ensuring the smoothness of sliding.

[0027] By designing a clever sliding and fixing mechanism, the fixed template 12 is flexibly installed and stably fixed on the first sliding track 4, thereby improving the applicability and reliability of the mold locking device.

[0028] like Figures 1 to 2 As shown, in some embodiments of this utility model, the width of the first connecting plate 33 is smaller than the width of the second connecting plate 34; The main purpose of this carefully designed setup is to more easily expose the mold cavity formed by the sliding template 11 and the fixed template 12. This not only greatly improves the visibility and convenience of operation, but also greatly facilitates the accurate placement of the robotic arm mold 100. With this setup, operators can easily observe the internal structure of the mold cavity, ensuring that the robotic arm mold 100 can be placed accurately and stably, thereby effectively improving production efficiency and the accuracy of mold use.

[0029] like Figures 1 to 2 As shown, in some embodiments of this utility model, the bottom surface of the first connecting plate 33 and the top surface of the second connecting plate 34 are both provided with sliding limiting components, and the sliding template 11 is disposed between the two sliding limiting components. The sliding limit assembly includes a second sliding rail 6 and a sliding slider 7. One side of the sliding slider 7 is slidably disposed on the second sliding rail 6, and the other side of the sliding slider 7 is fixedly connected to the sliding template 11. Specifically, the sliding slider 7 can be fixed to the sliding template 11 by means of bolt connection; This design allows the sliding template 11 to slide smoothly and precisely under the guidance of the second sliding rail 6, ensuring the smoothness and stability of the mold opening and closing action. The fixed connection between the sliding slider 7 and the sliding template 11 further enhances the overall stability of the mold structure, avoiding possible shaking or misalignment during mold opening and closing. Simultaneously, the sliding limit component effectively restricts the range of motion of the sliding template 11, ensuring the accuracy of the mold opening and closing stroke.

[0030] like Figures 1 to 2As shown, in some embodiments of this utility model, a through hole is provided on the first mounting plate 31, and a third connecting plate 51 is provided at one end of the power output shaft of the drive mechanism 5 that passes through the through hole. The end of the third connecting plate 51 away from the power output shaft is connected to the sliding template 11. The third connecting plate 51 and the sliding template 11 are connected and fixed by bolts; This design allows the drive mechanism 5 to effectively drive the sliding template 11 to open and close. The power output shaft passes through a through hole in the first mounting plate 31 and is connected to the sliding template 11 via the third connecting plate 51, ensuring direct and efficient power transmission. The bolted connection not only simplifies the installation process but also improves the stability and reliability of the connection, enabling it to withstand the significant forces generated during mold opening and closing, and preventing loosening or damage to the connection. Furthermore, this connection method facilitates the assembly and disassembly of the third connecting plate 51 and the sliding template 11, thereby simplifying subsequent maintenance and replacement work and reducing maintenance costs and time.

[0031] like Figures 1 to 2 As shown, in some embodiments of this utility model, operating grooves are provided on the edge of the sliding template 11 near the fixed template 12 and on the edge of the fixed template 12 near the sliding template 11. These operating grooves are designed to facilitate the operator's opening and closing of the mold, as well as subsequent maintenance and inspection. The operating grooves provide ample space for the operator's hands or tools to easily move the sliding template 11, enabling rapid mold opening and closing. Furthermore, the operating grooves also serve as inspection windows, allowing the operator to observe the internal condition of the mold without fully disassembling it, thus enabling timely detection and resolution of problems, improving work efficiency and mold safety.

[0032] This invention provides a mold-locking device for a robot arm mold, which can effectively ensure centering accuracy and pressure stability, thereby improving the reliability and precision of the mold-closing process and providing effective support for the molding of high-quality robot arms.
