Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing equipment industry, and more specifically to the field of molds, and more particularly to a quick-release mold with an automatic clamping mechanism. Background Technology

[0002] In existing stamping equipment, cutting equipment, and CNC lathes, there are generally mold structures for fixing and clamping the workpieces to be processed. The workpieces are fixed on the molds and then processed using various forming equipment.

[0003] In existing mold technologies, bidirectional screws are commonly used to drive clamping blocks to clamp workpieces. However, this method of moving the clamping blocks typically only clamps two end faces of the workpiece. Sometimes, the shape of the workpiece is not particularly regular. When clamping irregularly shaped workpieces, the contact area between the clamping blocks and the workpiece is small, resulting in the problem of insecure clamping of irregularly shaped workpieces during subsequent forming processes.

[0004] Furthermore, in the existing technology, due to the differences in the shape of the workpieces being processed, the equipment used for cutting, stamping and other forming processes generally still requires manual placement and clamping of the workpieces, which reduces the convenience of workpiece processing operations. Summary of the Invention

[0005] This invention proposes a quick-release mold with an automatic clamping mechanism, which solves the problems of unstable clamping and poor convenience in the existing mold structure when clamping workpieces.

[0006] The technical solution of the present invention is as follows: A quick-release mold with an automatic clamping mechanism, comprising a mold base, and further comprising:

[0007] The ring frame is fixedly connected to the top of the mold base. Multiple movable seats with adjustable planar positions are provided inside the ring frame. Workpiece clamping components with multiple different clamping blocks are rotatably arranged on the movable seats. The clamping blocks with different shapes are used to match the different clamping end faces of the irregular workpieces.

[0008] A cylindrical support is fixedly connected to the middle of the annular frame. An irregularly shaped workpiece is placed on the top of the cylindrical support. A longitudinally movable ejector block is provided in the middle of the cylindrical support. An elastic pushing component with an adjustable elastic distance is provided between the ejector block and the cylindrical support. The elastic pushing component is used to push the irregularly shaped workpiece out between multiple workpiece clamping components.

[0009] A circumferential adjustment mechanism is provided at the bottom of the mold base. The circumferential adjustment mechanism is used to drive multiple movable seats to move in the direction of the cylindrical support.

[0010] To adjust the circumferential position of the multiple movable seats, an annular slide rail is fixedly connected inside the annular frame, and multiple sliding seats are slidably arranged on the annular slide rail, with a compression ring between the tops of the multiple sliding seats.

[0011] To further fix the positions of the multiple sliding seats, the cylindrical support is fixedly connected to the annular frame by a support rod, and a screw fastener is provided between the compression ring and the corresponding support rod.

[0012] To adjust the position of the workpiece clamping assembly, the movable seat further includes a sliding block, a rotating rod, and a moving rod. The rotating rod is fixedly connected to the top of the sliding block, the workpiece clamping assembly is rotatably mounted on the rotating rod, and the moving rod is fixedly connected to the bottom of the sliding block. A trapezoidal groove is provided in the middle of the moving rod, and inclined surfaces are provided on both sides of the moving rod.

[0013] In order to move the moving seat and the workpiece clamping assembly toward the cylindrical support, a sliding groove is fixedly connected to the sliding seat, and the sliding block is slidably connected to the sliding groove.

[0014] To further process irregularly shaped workpieces, the workpiece clamping assembly includes a lifting sleeve and an insertion seat. The lifting sleeve is sleeved on the outside of the rotating rod. Multiple clamping blocks are fixedly connected to the middle circumference of the lifting sleeve. A conical discharge surface is provided at the top of the lifting sleeve. An insertion seat is provided at the top of the lifting sleeve. A cavity is provided inside the rotating rod. A meshing sleeve is provided inside the cavity. The bottom of the insertion seat meshes with the meshing sleeve. A spring damper is provided between the inner bottom wall of the cavity and the bottom of the insertion seat. A lens is provided through the top of the insertion seat.

[0015] To accommodate irregularly shaped workpieces, a bowl-shaped placement seat is fixedly connected to the top of the cylindrical support, and multiple friction strips are arranged circumferentially on the inner wall of the bowl-shaped placement seat.

[0016] To directly eject the processed irregularly shaped workpiece, the elastic pushing assembly further includes a receiving cylinder and a driving electric cylinder. A sliding rod is slidably connected through the receiving cylinder, and the ejection block is fixedly connected to the top of the sliding rod. A compression spring is provided between the receiving cylinder and the sliding rod. A position sensor is correspondingly provided between the inside of the receiving cylinder and the bottom of the sliding rod. A driving electric cylinder is provided inside the cylindrical support, and the output end of the driving electric cylinder is fixedly connected to the receiving cylinder.

[0017] To further adjust the positions of multiple movable seats, the circumferential adjustment mechanism includes a rotating base, an arc-shaped rack, and a rotating assembly. The rotating base is fixedly connected inside the mold base, and a threaded disc is rotatably connected inside the rotating base. Multiple threaded seats are threadedly connected to the threaded disc, and the threaded seats are slidably connected to the rotating base via sliding strips. The top of each threaded seat is fixedly connected to the arc-shaped rack, and the trapezoidal groove and the inclined surface both cooperate with the arc-shaped rack. A rotating assembly for driving the threaded disc to rotate is provided between the threaded disc and the rotating base.

[0018] To avoid multiple arc-shaped racks from contacting each other, the multiple arc-shaped racks are further arranged sequentially from low to high.

[0019] The working principle and beneficial effects of this invention are as follows:

[0020] 1. In this invention, when it is necessary to perform clamping operations on irregularly shaped workpieces, by rotating the lifting sleeve according to the shape of the area corresponding to the irregularly shaped workpiece, the position of the corresponding clamping block is aligned with the clamping end face of the irregularly shaped workpiece. Then, by driving multiple moving seats to move in the sliding groove through the circumferential adjustment mechanism, the clamping blocks can be moved together towards the cylindrical support, so that multiple clamping blocks can perform clamping operations on irregularly shaped workpieces, making it convenient to perform clamping operations on irregularly shaped workpieces without discrimination.

[0021] 2. In this invention, when an irregularly shaped workpiece needs to be placed on top of a cylindrical support, the receiving cylinder is driven to descend within the cylindrical support, allowing the compression spring to fully open. During the descent of the irregularly shaped workpiece, it contacts the ejector block and drives the sliding rod to descend. After corresponding with the position sensor, the moving seat begins to move, clamping the irregularly shaped workpiece. After completing the processing of the irregularly shaped workpiece, the receiving cylinder is driven to rise, causing the compression spring to tighten. At this time, the clamping of the moving seat is temporarily stopped by the circumferential adjustment mechanism. Under the action of the compression spring, the sliding rod is pushed upward, and then the ejector block is used to push the irregularly shaped workpiece upward from between multiple clamping blocks, which facilitates the automatic clamping of the irregularly shaped workpiece and the automatic release of the fixed irregularly shaped workpiece after processing.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 9 As shown, this embodiment proposes a quick-release mold with an automatic clamping mechanism, including a mold base 1. The mold base 1 is installed on the corresponding workpiece forming equipment, so that the center point of the annular frame 2 corresponds to the working end of the forming equipment. The mold base 1 is also equipped with an annular frame 2, which is fixedly connected through the top of the mold base 1. An annular slide rail 6 is fixedly connected inside the annular frame 2. Multiple sliding seats 7 are slidably arranged on the annular slide rail 6. An extrusion ring 8 is arranged between the tops of the multiple sliding seats 7. According to the end face that the irregular workpiece needs to be clamped, the circumferential position of the sliding seats 7 on the annular slide rail 6 is adjusted. After the adjustment is completed, the extrusion ring 8 extrudes and fixes the multiple sliding seats 7. The top of the sliding seat 7 is provided with an arc-shaped groove, and the bottom of the extrusion ring 8 is wedge-shaped, so that the bottom of the extrusion ring 8 can make full contact with the arc-shaped groove to fix the sliding seat 7.

[0035] The annular frame 2 is provided with multiple adjustable planar movable seats. Each movable seat includes a sliding block 10, a rotating rod 11, and a moving rod 12. The rotating rod 11 is fixedly connected to the top of the sliding block 10. The workpiece clamping assembly is rotatably mounted on the rotating rod 11. The moving rod 12 is fixedly connected to the bottom of the sliding block 10. A trapezoidal groove is provided in the middle of the moving rod 12. Inclined surfaces are provided on both sides of the moving rod 12. The rotating rod 11 is used to install the lifting sleeve 14, while the moving rod 12 is used to move the sliding block 10, the rotating rod 11, and the moving rod 12 together toward the cylindrical support 4 under the drive of the arc rack 30.

[0036] A sliding groove 13 is fixedly connected to the sliding seat 7, and a sliding block 10 is slidably connected in the sliding groove 13. When the position of the sliding seat 7 is adjusted, the position of the sliding groove 13 is also adjusted, thereby adjusting the movement path of the sliding block 10, the rotating rod 11 and the moving rod 12.

[0037] A workpiece clamping assembly with multiple different clamping blocks 3 is rotatably mounted on the movable seat. The clamping blocks 3 of different shapes are used to match the different clamping end faces of irregularly shaped workpieces. The workpiece clamping assembly includes a lifting sleeve 14 and an insertion seat 15. The lifting sleeve 14 is sleeved on the outside of the rotating rod 11. Multiple clamping blocks 3 are fixedly connected to the middle circumference of the lifting sleeve 14. A conical discharge surface 35 is provided at the top of the lifting sleeve 14. An insertion seat 15 is provided at the top of the lifting sleeve 14. A cavity is provided inside the rotating rod 11. An engagement sleeve 16 is provided inside the cavity. The bottom of the insertion seat 15 engages with the engagement sleeve 16. The inner bottom wall of the cavity is flush with the bottom of the insertion seat 15. A spring damper 17 is provided between the insert seat 15 and a lens 18 is provided through the top of the insert seat 15. First, according to the shape of the clamping end face of the clamped irregular workpiece, the lifting sleeve 14 is moved upward to release the engagement between the insert seat 15 and the engagement sleeve 16. Then, the lifting sleeve 14 is rotated to move the corresponding clamping block 3 toward the cylindrical support 4. Then, the lifting sleeve 14 is released and, under the action of the spring damper 17, the lifting sleeve 14 is moved downward to re-engage the insert seat 15 and the engagement sleeve 16. By providing the lens 18, the engagement relationship between the insert seat 15 and the engagement sleeve 16 can be observed.

[0038] When it is necessary to remove the processed irregular workpiece, after the ejector block 5 drives the irregular workpiece to rise, the irregular workpiece moves to the conical discharge surface 35, so that the irregular workpiece rises along the inclined side wall of the conical discharge surface 35, and the unloading operation of the irregular workpiece is completed.

[0039] The dimensions of the lifting sleeve 14 vary depending on the shape of the different irregular workpieces.

[0040] The cylindrical support 4 is fixedly connected to the middle of the annular frame 2. The cylindrical support 4 is fixedly connected to the annular frame 2 through the support rod 9. A screw fastener is provided between the extrusion ring 8 and the corresponding support rod 9. The screw fastener includes a lifting screw 31. The lifting screw 31 is threadedly connected to the support rod 9. The bottom of the lifting screw 31 is rotatably connected to the extrusion ring 8. Rotating the lifting screw 31 causes the extrusion ring 8 to descend and extrude and fix the sliding seat 7.

[0041] The irregularly shaped workpiece is placed on the top of the cylindrical support 4. A bowl-shaped placement seat 19 is fixedly connected to the top of the cylindrical support 4. Multiple friction strips 20 are arranged around the inner wall of the bowl-shaped placement seat 19. The irregularly shaped workpiece to be processed is placed on the bowl-shaped placement seat 19. The bottom end of the irregularly shaped workpiece contacts the multiple friction strips 20, so that the irregularly shaped workpiece will not move at will.

[0042] A longitudinally movable ejector block 5 is provided in the middle of the cylindrical support 4. An elastic pushing component with an adjustable elastic distance is provided between the ejector block 5 and the cylindrical support 4. The elastic pushing component is used to push the irregular workpiece out between multiple workpiece clamping components. The elastic pushing component includes a receiving cylinder 21 and a driving electric cylinder 25. A sliding rod 22 is slidably connected through the receiving cylinder 21. The ejector block 5 is fixedly connected to the top of the sliding rod 22. A compression spring 23 is provided between the receiving cylinder 21 and the sliding rod 22. When it is necessary to place the irregular workpiece on the top of the cylindrical support 4, the driving electric cylinder 25 is activated to drive the receiving cylinder 21 to descend within the cylindrical support 4, so that the compression spring 23 is fully opened. During the descent of the irregular workpiece, after contacting the ejector block 5, it drives the sliding rod 22 to descend.

[0043] Among them, a position sensor 24 is correspondingly arranged between the inside of the storage cylinder 21 and the bottom of the sliding rod 22. A drive electric cylinder 25 is arranged inside the cylindrical support 4. The output end of the drive electric cylinder 25 is fixedly connected to the storage cylinder 21. During the descent of the sliding rod 22, after the position sensor 24 at the bottom of the sliding rod 22 corresponds to the position sensor 24 inside the storage cylinder 21, it is determined that the placement height of the irregular workpiece corresponds to the height of the clamping block 3. The sliding block 10 is moved so that multiple clamping blocks 3 contact the clamping end face of the irregular workpiece.

[0044] After completing the processing of the irregular workpiece, the drive electric cylinder 25 is started to drive the receiving cylinder 21 to rise, so that the compression spring 23 is tightened. At this time, the clamping of the moving seat is temporarily stopped by the circumferential adjustment mechanism. Under the action of the compression spring 23, the sliding rod 22 is pushed upward, and then the ejector block 5 is used to push the irregular workpiece upward from between multiple clamping blocks 3.

[0045] A circumferential adjustment mechanism is provided at the bottom of the mold base 1. This mechanism drives multiple movable seats to move towards the cylindrical support 4. The circumferential adjustment mechanism includes a rotating base 26, an arc-shaped rack 30, and a rotating assembly. The rotating base 26 is fixedly connected inside the mold base 1. A threaded disc 27 is rotatably connected inside the rotating base 26. Multiple threaded seats 28 are threadedly connected to the threaded disc 27. The threaded seats 28 are slidably connected to the rotating base 26 via a sliding strip 29. An arc-shaped rack 30 is fixedly connected to the top of each threaded seat 28. The trapezoidal groove and the inclined surface both cooperate with the arc-shaped rack 30. A rotating component for driving the threaded disk 27 to rotate is provided between the threaded disk 27 and the rotating base 26. Multiple arc-shaped racks 30 are arranged in sequence from low to high. The rotating component drives the threaded disk 27 to rotate, causing the threaded seat 28 to move along the outer wall of the sliding bar 29. The threaded seat 28 and the arc-shaped rack 30 move laterally together, so that the arc-shaped rack 30 contacts the trapezoidal groove or the inclined surface, driving the sliding block 10 to move in the sliding groove body 13, so that the clamping block 3 contacts the irregular workpiece.

[0046] The inner arc surface of the arc rack 30 is provided with tooth blocks. The volume of the tooth blocks corresponds to the inner wall of the trapezoidal groove, and the outer wall of the tooth blocks corresponds to the outer wall size of the inclined surface. This makes it easy for the arc rack 30 to make stable contact with the moving rod 12. However, because the volume difference of the irregular workpiece is large, there is sometimes a problem that the moving distance of the moving seat is long. By setting different heights for multiple arc racks 30, it is easy for multiple arc racks 30 to intersect each other, thereby increasing the moving distance of the arc rack 30.

[0047] The rotating assembly includes an annular conical gear groove 32. A slot is provided on one side of the bottom of the rotating base 26. A transmission conical gear 33 is meshed on the annular conical gear groove 32. A drive motor 34 is provided on the mold base 1. The transmission conical gear 33 is located on the output end of the drive motor 34. When the drive motor 34 is started, the threaded disc 27 is driven to rotate within the rotating base 26 through the transmission relationship between the transmission conical gear 33 and the annular conical gear groove 32.

[0048] The working principle of this quick-release mold with an automatic clamping mechanism:

[0049] First, install the mold base 1 and various components onto the corresponding workpiece forming equipment;

[0050] According to the shape of the irregular workpiece being processed, the lifting sleeve 14 is first moved upward to release the meshing relationship between the insertion seat 15 and the engagement sleeve 16. Then, the lifting sleeve 14 is rotated so that the corresponding clamping block 3 is oriented toward the cylindrical support 4. Then, the lifting sleeve 14 is released and, under the action of the spring damper 17, the lifting sleeve 14 is moved downward so that the insertion seat 15 and the engagement sleeve 16 are re-engaged.

[0051] During the processing of irregularly shaped workpieces, when the irregularly shaped workpiece is first placed on the top of the cylindrical support 4, the drive electric cylinder 25 is started to drive the receiving cylinder 21 to descend within the cylindrical support 4, so that the compression spring 23 is fully opened. During the descent of the irregularly shaped workpiece, after contacting the ejector block 5, the sliding rod 22 is driven to descend. During the descent of the sliding rod 22, the position sensor 24 at the bottom of the sliding rod 22 corresponds with the position sensor 24 inside the receiving cylinder 21, and the placement height of the irregularly shaped workpiece corresponds to the height of the clamping block 3. According to the preset program, the drive motor 34 starts automatically, and through the transmission relationship between the bevel gear 33 and the annular bevel gear groove 32, the threaded disc 27 is driven to rotate within the rotating base 26, so that the threaded seat 28 moves along the outer wall of the sliding bar 29. The threaded seat 28 and the arc rack 30 move laterally together, so that the arc rack 30 contacts the trapezoidal groove or inclined surface, and the sliding block 10 moves within the sliding groove 13, so that the clamping block 3 contacts and clamps the irregularly shaped workpiece.

[0052] After the irregular workpiece is processed, the drive electric cylinder 25 is started to drive the receiving cylinder 21 to rise, so that the compression spring 23 is tightened. At this time, the clamping of the moving seat is temporarily stopped by the circumferential adjustment mechanism. Under the action of the compression spring 23, the sliding rod 22 is pushed upward. Then, the ejector block 5 is used to push the irregular workpiece upward from between multiple clamping blocks 3, so that the irregular workpiece rises along the outer wall of multiple conical discharge surfaces 35. Finally, the irregular workpiece is taken out.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
