Description

Technical Field

[0001] The present invention relates to the technical field of mold equipment, and in particular to a balancing block fixing device. Background Art

[0002] Drawing is a common process for automotive panels. The blank holder and balancing weights control material flow. During die commissioning, the gap between the blank holder and the upper die is often increased or decreased by adding or removing shims beneath the balancing weights to control material flow. Traditionally, bolts are used to secure the balancing weights, making them difficult to disassemble and reassemble during commissioning. This tedious process requires repeated disassembly and installation, resulting in time-consuming and inefficient operations. Summary of the Invention

[0003] In view of this, an object of the present invention is to provide a balancing weight fixing device to solve the problem of inconvenient operation during the debugging process.

[0004] Based on the above-mentioned purpose, the present invention provides a balancing block fixing device, including a lower mold body and a balancing block, a balancing groove is opened on the lower mold body, the balancing block is installed in the balancing groove, a positioning mechanism is arranged between the balancing block and the lower mold body, the positioning mechanism is used to locate the plane position of the balancing block, a bracket body is installed on one side of the balancing groove on the lower mold body, a rotating mechanism is arranged on the bracket body, and a pressing mechanism is arranged at the lower end of the rotating mechanism, and the pressing mechanism is driven to rotate by the rotating mechanism so that the pressing mechanism presses and fixes the balancing block.

[0005] A further improvement is that the rotating mechanism includes a rotating column rotatably connected to the bracket body, and the upper end of the rotating column is fixedly connected to a shift rod.

[0006] A further improvement is that a torsion spring is sleeved on the rotating column, a spring stop block is fixedly connected to the upper side of one end of the bracket body, and both ends of the torsion spring are respectively connected to the shift rod and the spring stop block.

[0007] A further improvement is that the pressing mechanism includes a pressing plate fixedly connected to the lower end of the rotating column, and an adjusting plate is provided on the lower side of the pressing plate.

[0008] A further improvement is that a mounting groove is opened on the lower side of the pressure plate, the adjustment plate is slidably installed in the mounting groove, and an extrusion spring is connected between the upper end of the adjustment plate and the inner wall of the mounting groove.

[0009] A further improvement is that a pressing surface is provided on one side of the balancing block, the pressing surface is tilted, and the lower end of the adjustment plate is tilted.

[0010] A further improvement is that a pressure plate stop block is fixedly connected to the lower side of the other end of the bracket body.

[0011] A further improvement is that the positioning mechanism includes a positioning pin, which is installed in the balancing groove, and a through hole is opened on the balancing block, and the positioning pin and the through hole are adapted to each other.

[0012] A further improvement is that the bracket body is fixedly mounted on the lower mold body by bolts.

[0013] The beneficial effects of the present invention are as follows: by opening a balancing groove on the lower mold body for installing the balancing block, and setting a positioning mechanism, the balancing block is positioned by the positioning pin corresponding to the through hole on the balancing block, thereby ensuring the position of the balancing block on the plane of the lower mold body and ensuring the accuracy of the position.

[0014] By setting a bracket body on one side of the balancing groove for the installation of the rotating mechanism and the pressing mechanism, the balancing block is pressed by the pressing plate to control the up and down movement of the balancing block, and the pressing plate is driven to rotate by pushing the rotating column through the lever. The balancing block limit is released only by rotation, and the balancing block can be easily removed and the gasket can be added or reduced, which greatly improves the convenience of operation. An adjustment plate is set on the lower side of the pressing plate. As the pressing plate rotates, the inclined surface of the lower end of the adjustment plate contacts the inclined pressing surface. As the height of the pressing surface changes, the adjustment plate contracts and presses against the inner wall of the installation groove. The reaction force presses the balancing block to keep it stable, reducing the instability caused by the gap in the pressure plate limit after the balancing block is debugged, further improving the limiting effect of the balancing block, and improving the stability of the balancing block installation.

[0020] like Figure 1 、 Figure 2 As shown, a balancing block fixing device includes a lower mold body 1 and a balancing block 2. A balancing groove is provided on the lower mold body 1, and the balancing block 2 is installed in the balancing groove. A positioning mechanism is provided between the balancing block 2 and the lower mold body 1. The positioning mechanism is used to locate the plane position of the balancing block 2. The positioning mechanism includes a positioning pin 14, which is installed in the balancing groove. A through hole 15 is provided on the balancing block 2, and the positioning pin 14 and the through hole 15 are adapted to each other. The balancing block 2 is inserted into the through hole 15 through the positioning pin 14 for positioning and installation.

[0021] like Figure 3 As shown, a bracket body 3 is mounted on one side of the balancing groove on the lower die body 1, and the bracket body 3 is fixed to the lower die body 1 by bolts 16. A rotating mechanism is provided on the bracket body 3, and a pressing mechanism is provided at the lower end of the rotating mechanism. The pressing mechanism is driven by the rotating mechanism to rotate, so that the pressing mechanism extends into the balancing groove to press and fix the balancing weight 2.

[0022] The rotating mechanism includes a rotating column 4 rotatably connected to the bracket body 3. A lever 5 is fixedly connected to the upper end of the rotating column 4, which is driven by the lever 5 to rotate the rotating column 4. A torsion spring 6 is sleeved on the rotating column 4. A spring stopper 7 is fixedly connected to the upper side of one end of the bracket body 3. The ends of the torsion spring 6 are respectively connected to the lever 5 and the spring stopper 7. After rotation, the torsion spring 6 drives the rotating column 4 to rotate and reset, causing the pressing mechanism to press the balancing weight 2.

[0023] like Figure 2 、 4 As shown in Figures 5 and 6, the pressing mechanism includes a pressing plate 8 fixedly connected to the lower end of the rotating column 4, which is driven by the rotating column 4 to rotate the pressing plate 8 to achieve the pressing and loosening of the balancing block 2; an adjusting plate 9 is provided on the lower side of the pressing plate 8, and a mounting groove 10 is provided on the lower side of the pressing plate 8. The adjusting plate 9 is slidably installed in the mounting groove 10, and an extrusion spring 11 is connected between the upper end of the adjusting plate 9 and the inner wall of the mounting groove 10. A pressing surface 12 is provided on one side of the balancing block 2, and the pressing surface 12 is tilted. The lower end of the adjusting plate 9 is tilted, and the inclined surface of the lower end of the adjusting plate 9 contacts the pressing surface 12 of the balancing block 2 as the pressing plate 8 rotates. As the pressing surface 12 gradually tilts, the adjusting plate 9 shrinks and fits into the mounting groove 10, and the balancing block 2 is pressed by the adjusting plate 9, so that the installation of the balancing block 2 is more stable.

[0024] like Figure 3 As shown, a pressure plate stop block 13 is fixedly connected to the lower side of the other end of the bracket body 3. The pressure plate stop block 13 limits the rotation of the pressure plate 8 to ensure that the pressure plate 8 is located above the balancing block 2, thereby stabilizing the pressing effect.

[0025] When in use, the rotating column 4 is rotated by the shift lever 5, so that the pressure plate 8 is rotated from the balancing groove to the lower side of the bracket body 3, and the balancing weight 2 is placed in the balancing groove, and is positioned and placed by the positioning pin 14 and the through hole 15 to ensure the accuracy of the plane position; release the shift lever 5, the rotating column 4 is rotated and reset by the action of the torsion spring 6, and the rotating column 4 drives the pressure plate 8 to rotate back into the balancing groove and is located on the upper side of the pressing surface 12, and the adjusting plate 9 is extended and fitted on the pressing surface 12 by the extrusion spring 11. The inclined surface of the adjusting plate 9 contacts the inclined surface 12 of the pressing surface 12. As the rotating column 4 rotates, the adjusting plate 9 is squeezed inwardly and finally fits into the inner wall of the installation groove 10, thereby pressing against the balancing weight 2, so that the balancing weight 2 remains stable. During the debugging process, if it is necessary to add or reduce the gasket under the balancing weight, it is only necessary to pull the shift lever 5 to make the rotating column 4 drive the pressure plate 8 to rotate away from the balancing weight 2, and the balancing weight can be quickly taken out for adjustment, which greatly improves the convenience of adjustment.
