Description

Technical Field

[0001] This utility model relates to the field of mold base auxiliary equipment technology, specifically a mold base clamping device that facilitates positioning. Background Technology

[0002] In mold processing and use, the clamping device of the mold base is one of the key pieces of equipment to ensure processing accuracy and production efficiency. Existing technologies, such as the positioning clamping device disclosed in patent CN202322932552.3, while achieving workpiece clamping and positioning to a certain extent, still have some problems.

[0003] This device primarily uses a stepper motor to drive the platform rotation and employs horizontal and vertical bidirectional lead screws to adjust the clamping position. While it offers a degree of flexibility and adaptability, in practical applications, the adjustment process is quite complex for mold bases of different sizes and shapes, requiring multiple adjustments of the horizontal and vertical lead screws to achieve accurate clamping and positioning. Furthermore, the device lacks precise control over the clamping force during clamping, which can easily damage the mold base, affecting its lifespan and processing quality. Simultaneously, its relatively complex structure and numerous components result in high manufacturing costs and make maintenance and repair difficult. Therefore, existing mold base clamping devices still require further improvement in terms of adaptability, clamping accuracy, ease of operation, and cost control. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a mold base clamping device for easy positioning, comprising a mounting platform and two driving components. The mounting platform has a rectangular cavity inside, and four sliding grooves perpendicular to the side edges of its side walls are formed on the top wall of the mounting platform. The two driving components are symmetrically installed in the rectangular cavity of the mounting platform, and the two driving components are located at the corners of the mounting platform. Each driving component includes a driving element and two first clamping plates. The driving element is fixedly connected to the mounting platform, and the two first clamping plates are slidably installed in two adjacent sliding grooves. The output shaft of the driving element is connected to the two first clamping plates for transmission, and the driving element drives the two first clamping plates away from or towards the upper center of the mounting platform.

[0006] Optionally, the driving component further includes a first link, a second link, and a third link. The output shaft end of the driving component is fixedly installed with the middle part of the first link. The two ends of the first link are respectively hinged to the second link and the third link. The end of the second link away from the first link is hinged to a first clamping plate. The end of the third link away from the first link is hinged to another first clamping plate.

[0010] (III) Beneficial Effects This utility model provides a mold base clamping device that facilitates positioning, and has the following beneficial effects: 1. This easy-to-position mold base clamping device employs two symmetrically distributed driving components. Each driving component consists of a driving element, a first connecting rod, a second connecting rod, a third connecting rod, and a first clamping plate. This structural design allows the clamping device to be flexibly adjusted according to the size and shape of the mold base. The output shaft of the driving element, through the transmission of the first, second, and third connecting rods, can precisely control the movement position and clamping force of the first clamping plate. Compared with the prior art, the clamping device of this invention can automatically adapt to changes in the size of the mold base during clamping, eliminating the need for multiple adjustments to the transverse and longitudinal lead screws, thereby significantly improving the adaptability and accuracy of clamping.

[0011] 2. The clamping device of this utility model has a relatively simple structure and fewer parts, mainly consisting of a mounting platform, a driving component, a connecting rod, and a clamping plate. Compared with the complex structures in existing technologies, it greatly simplifies the manufacturing process and reduces manufacturing costs. At the same time, due to the simplified structure, the maintenance and repair of the equipment are more convenient and faster, reducing downtime and maintenance costs.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0017] Please see Figures 1 to 5 The present invention provides a technical solution: a mold base clamping device for easy positioning, including a mounting platform 1 and two driving components. The mounting platform 1 has a rectangular cavity inside, and four sliding grooves are respectively perpendicular to the side edges of its side walls on the top wall of the mounting platform 1.

[0018] Two drive components are symmetrically installed in the rectangular cavity of the mounting platform 1, and the two drive components are located at the corners of the mounting platform 1.

[0019] The driving component includes a driving element 2 and two first clamping plates 11. The driving element 2 is fixedly connected to the mounting platform 1. The two first clamping plates 11 are slidably installed in two adjacent sliding grooves. The output shaft of the driving element 2 is connected to the two first clamping plates 11 for transmission. The driving element 2 drives the two first clamping plates 11 away from or closer to the upper center of the mounting platform 1.

[0020] The mounting platform 1 supports the mold base. Two drive components are used to clamp and fix the mold base. The drive component 2 drives two first clamping plates 11 to slide on the mounting platform 1. When the two first clamping plates 11 move closer to the upper center of the mounting platform 1, they clamp and fix the lateral edges of the mold base. When the two first clamping plates 11 move away from the upper center of the mounting platform 1, they release the lateral edges of the mold base.

[0021] Specifically, the driving component further includes a first connecting rod 5, a second connecting rod 9, and a third connecting rod 10. The output shaft end of the driving component 2 is fixedly installed to the middle of the first connecting rod 5, and both ends of the first connecting rod 5 are hinged to the second connecting rod 9 and the third connecting rod 10, respectively. The end of the second connecting rod 9 away from the first connecting rod 5 is hinged to a first clamping plate 11. The end of the third connecting rod 10 away from the first connecting rod 5 is hinged to another first clamping plate 11. The driving component 2 includes, but is not limited to, a servo electric cylinder or an electric push rod.

[0022] The driving component 2, acting as a power source, employs a servo electric cylinder or electric push rod to precisely control its extension and retraction stroke. When the driving component 2 extends, it pushes the first connecting rod 5 to move via the connecting block 3. The two ends of the first connecting rod 5 are hinged to the second connecting rod 9 and the third connecting rod 10, respectively. This hinged structure allows the movement of the first connecting rod 5 to be transmitted to the first clamping plate 11 via the second connecting rod 9 and the third connecting rod 10. The second connecting rod 9 and the third connecting rod 10 are also hinged to the first clamping plate 11, allowing the first clamping plate 11 to slide within the groove of the mounting platform 1. This linkage transmission structure converts the linear motion of the driving component 2 into the clamping or releasing action of the first clamping plate 11, thereby achieving the clamping or releasing of the mold base. The design of the driving component 2 using a servo electric cylinder or electric push rod allows the clamping device to precisely control the clamping force and position according to different mold base sizes and processing requirements. The servo electric cylinder has high-precision control capabilities, enabling precise control of minute strokes, thus ensuring the uniformity and stability of the clamping force. Electric actuators are characterized by their simple structure, low cost, and ease of maintenance, making them suitable for applications where clamping force requirements are not high. By employing one of these two drive components, users can select the appropriate drive method based on their actual needs, improving the applicability and economy of the clamping device. Furthermore, servo electric cylinders and electric actuators offer fast response times, enabling rapid clamping or releasing actions and enhancing production efficiency.

[0023] More specifically, the angle between the first link 5 and the second link 9 or the third link 10 is less than 90 degrees.

[0024] The first link 5, the second link 9, and the third link 10 form a stable triangular structure. This structure has high mechanical stability, ensuring the reliability and accuracy of the clamping action. When the drive component 2 extends, the first link 5 pushes the second link 9 and the third link 10, causing the first clamping plate 11 to move closer to the mold base. Because the included angle is less than 90 degrees, the first clamping plate 11 can maintain a stable clamping force during movement, preventing the mold base from loosening due to insufficient clamping force. At the same time, when the drive component 2 retracts, the first link 5 can smoothly pull the second link 9 and the third link 10, causing the first clamping plate 11 to return to its original position, ensuring the normal operation of the clamping device. Furthermore, the included angle between the first link 5 and the second link 9 or the third link 10 is less than 90 degrees, which can avoid jamming in the transmission process and ensure a smooth clamping process.

[0025] More specifically, the first connecting rod 5 is hinged to the second connecting rod 9 via the second rotating shaft 8, and the first connecting rod 5 is hinged to the third connecting rod 10 via the first rotating shaft 7. A connecting block 3 is fixedly installed on the output shaft end of the drive component 2, and the connecting block 3 is fixedly connected to the first connecting rod 5.

[0026] The first connecting rod 5 can flexibly adjust its relative position with the second connecting rod 9 and the third connecting rod 10 during movement. This hinged structure not only ensures the flexibility of transmission but also adapts to the clamping requirements of mold bases of different sizes. The connecting block 3 is fixedly connected to the output shaft end of the drive component 2 and to the first connecting rod 5, serving to transmit power. When the drive component 2 extends or retracts, the connecting block 3 transmits power to the first connecting rod 5, thereby driving the movement of the entire clamping mechanism.

[0027] A torsion spring is installed between the first link 5 and the second link 9, and a torsion spring is also installed between the first link 5 and the third link 10.

[0028] In use, the mold base is first placed on the mounting platform 1. Then, the drive unit 2 extends, pushing the first connecting rod 5 to move via the connecting block 3. Because a torsion spring is provided between the first connecting rod 5 and the second connecting rod 9 and the third connecting rod 10, the first connecting rod 5 pushes the first clamping plate 11 to slide within the groove of the mounting platform 1, moving closer to the mold base. When the first clamping plate 11 contacts the mold base, as the drive unit 2 continues to extend, it pushes the first connecting rod 5 to rotate around the first rotating shaft 7 via the connecting block 3, thus twisting the internal torsion spring. The first connecting rod 5 continues to push the first clamping plate 11 closer to the mold base via the second connecting rod 9, while the second connecting rod 9 rotates around the second rotating shaft 8, twisting the internal torsion spring. When the first clamping plate 11 fully contacts the mold base, the drive unit 2 stops extending, at which point the first clamping plate 11 clamps the mold base.

[0029] When it is necessary to release the mold base, the drive component 2 retracts, pulling the first connecting rod 5 back to its original position via the connecting block 3. The first connecting rod 5 then pulls the two first clamping plates 11 back to their original position via the second connecting rod 9 and the third connecting rod 10. Once the torsion springs inside the second connecting rod 9 and the third connecting rod 10 have reset, the retraction of the drive component 2 causes the two first clamping plates 11 to fully reset, thereby releasing the mold base.
