[0001] This utility model relates to the field of stamping technology, and in particular to a stamping device that facilitates quick mold changes. Background Technology

[0002] In modern manufacturing, stamping technology, with its advantages of high efficiency, energy saving, and high material utilization, is widely used in many fields such as automobiles, electronics, and aerospace. From automobile body panels and engine parts to the outer shells and internal structural components of electronic products, stamped parts are ubiquitous and are one of the key links in achieving mass production.

[0003] The common way to connect the molds of existing stamping equipment is to install the molds on the stamping machine by bolts. When changing the mold, workers need to use a variety of tools to unscrew a large number of bolts one by one. This process is not only physically demanding, but also extremely time-consuming. In addition, the molds are heavy, making them difficult to move during mold changing and posing certain safety risks, which is quite inconvenient.

[0004] Therefore, a stamping device that facilitates quick mold replacement for stamping presses has been developed, which can also assist in mold handling during the mold replacement process, saving manpower and improving mold replacement efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing stamping devices, such as time-consuming mold changes, heavy molds that are difficult to transport during mold changes, certain safety risks, and inconvenience, this utility model provides a stamping device that facilitates quick mold changes, assists in mold transportation during the mold change process, saves manpower, and improves mold change efficiency.

[0006] The technical solution is as follows: A stamping device that facilitates quick mold changing includes a stamping press, molds, positioning blocks, rotating shafts, worm gears, worm wheels, rotating frames, connecting rods, limiting blocks, and a mold removal assembly. The stamping press has two molds, upper and lower, with positioning blocks engaged on both sides of the molds. Rotating shafts are rotatably connected to both the upper and lower parts of the stamping press, and worm gears are connected to both shafts. Worm wheels are rotatably connected to both the upper and lower parts of the stamping press, and each worm gear meshes with an adjacent worm. A rotating frame is connected to each worm. Two limiting blocks are slidably connected to both the upper and lower parts of the stamping press, and each limiting block engages with an adjacent positioning block. A connecting rod connects each limiting block to the rotating frame. The stamping press is equipped with a mold removal assembly that assists in removing the molds.

[0007] Furthermore, each positioning block has a slot at its lower part.

[0008] Furthermore, it also includes a rotating handle, with a rotating handle snapped onto each shaft.

[0009] Furthermore, the rotating handle is connected to a square boss.

[0010] Furthermore, the demolding assembly includes an electric push rod, a tilting frame, a first pulley, an extrusion roller, an extrusion frame, a guide rod, a telescopic spring, a top block, and a second pulley. The electric push rod is connected to the lower right side of the press, and the tilting frame is rotatably connected to the right side of the press. The tilting frame is connected to the telescopic end of the electric push rod. The tilting frame is equipped with multiple first pulleys. The extrusion roller is rotatably connected to the left front of the tilting frame. Two guide rods are connected to the lower part of the press, and the guide rods are located below the lower mold. The extrusion frame is slidably connected between the guide rods. Each guide rod is connected to the extrusion frame with a telescopic spring. The extrusion frame and the extrusion roller are in a pressing fit. The top block is slidably connected to the lower part of the press. The top block is located between the extrusion frame and the mold. Multiple second pulleys are rotatably connected to the top block, and the top block is in a pressing fit with the extrusion frame.

[0011] Furthermore, the right side of the extrusion frame has an oblique structure.

[0012] The beneficial effects are as follows: After placing the mold on the stamping machine, inserting the positioning block, and then rotating the rotating handle, the limiting block is locked and fixed to the positioning block, thus completing the mold replacement.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] A stamping device that facilitates quick die change, such as Figure 1-6 As shown, the assembly includes a stamping press 1, a die 2, a positioning block 3, a rotating handle 4, a rotating shaft 5, a worm gear 6, a worm wheel 7, a rotating frame 8, a connecting rod 9, a limiting block 10, and a die removal assembly. Two dies 2 are placed on the stamping press 1. Positioning blocks 3 are engaged with both sides of the dies 2. Rotating shafts 5 are rotatably connected to both the upper and lower parts of the stamping press 1. Rotating handles 4 are engaged with each rotating shaft 5. The rotating handles 4 are connected to square bosses for easy docking and disassembly of the rotating shafts 5. Each part of the press 1 is connected to a worm gear 6. Both the upper and lower parts of the press 1 are also rotatably connected to worm wheels 7. The worm wheels 7 mesh with the adjacent worm gear 6. Each worm gear 6 is connected to a rotating frame 8. The upper and lower parts of the press 1 are slidably connected to two left and right limiting blocks 10. Each limiting block 10 is engaged with the adjacent positioning block 3. Each limiting block 10 is connected to the rotating frame 8 by a connecting rod 9. Each positioning block 3 has a locking groove at the bottom to facilitate engagement with the limiting block 10. The press 1 is equipped with a mold removal assembly.

[0022] The demolding assembly includes an electric push rod 11, a tilting frame 12, a first pulley 13, an extrusion roller 14, an extrusion frame 15, a guide rod 16, a telescopic spring 17, a top block 18, and a second pulley 19. The electric push rod 11 is connected to the lower right side of the press 1. The tilting frame 12 is rotatably connected to the right side of the press 1. The tilting frame 12 is connected to the telescopic end of the electric push rod 11. Fourteen first pulleys 13 are provided on the tilting frame 12. An extrusion roller 14 is rotatably connected to the front left side of the tilting frame 12. Two guide rods 16 are connected to the lower part of the press 1. 6. Guide rods 16 are located below the lower mold 2. Extrusion frames 15 are slidably connected between the guide rods 16. Each guide rod 16 is connected to the extrusion frame 15 by a telescopic spring 17. The extrusion frame 15 is in extrusion engagement with the extrusion roller 14. A top block 18 is slidably connected to the lower part of the press 1. The top block 18 is located between the extrusion frame 15 and the mold 2. Fourteen second pulleys 19 are rotatably connected to the top block 18. The top block 18 is in extrusion engagement with the extrusion frame 15. The right side of the extrusion frame 15 has an inclined structure, which can lift the top block 18 upward.

[0023] When using this invention, first place the device in the stamping area of ​​the workpiece, then place the workpiece between the upper and lower dies 2. Starting the stamping press 1 causes the upper die 2 to press down, stamping the workpiece. When a die change is needed, the rotating handle 4 can be engaged with the rotating shaft 5. Rotating the rotating handle 4 causes the rotating shaft 5 to rotate, driving the worm gear 6 to rotate. Through the meshing motion of the worm gear 6 and the worm wheel 7, the worm wheel 7 rotates, driving the rotating frame 8 to rotate. This causes the connecting rod 9 to rotate between the rotating frame 8 and the limiting block 10, pulling the limiting frame to slide inwards and retract. Once the limiting bracket is disengaged from the positioning block 3, the positioning block 3 can be removed, thus releasing the lock on mold 2 and facilitating mold 2 replacement. After the replacement mold 2 is repositioned on the stamping machine 1, the positioning block 3 is reinserted to engage mold 2. Then, the rotating handle 4 is rotated in the opposite direction, causing the rotating shaft 5 to reverse, allowing the limiting block 10 to slide back into the positioning block 3 and secure it. The rotating handle 4 can then be removed to prevent accidental contact during stamping that could loosen mold 2. When it is necessary to remove the unlocked mold 2 from the stamping machine 1... The electric actuator 11 can be activated, causing its telescopic end to extend upwards. This rotates the tilting frame 12 upwards until it is parallel to the mold 2. During the rotation of the tilting frame 12, the pressure roller rotates, causing it to press the extrusion frame 15. This causes the extrusion frame 15 to slide to the left on the guide rod 16, compressing the telescopic spring 17. Through the sliding engagement between the extrusion frame 15 and the top block 18, the top block 18 is lifted upwards, thus lifting the mold 2 off the press 1. The mold 2 is then pushed forward, guided by the rotation of the first pulley 13 and the second pulley 19. The mold 2 can be easily pushed onto the tilting frame 12. Then, the electric push rod 11 is activated, causing the telescopic end of the electric push rod 11 to retract, which tilts the tilting frame 12 and slowly lowers the mold 2 off the tilting frame 12. Similarly, the mold 2 can be placed on the tilting frame 12 and pushed to the installation position. Then, the tilting frame 12 is reset, and the telescopic spring 17 returns, which can accurately place the mold 2 on the stamping machine 1. This facilitates the quick replacement of the mold 2 on the stamping machine 1 and assists in the handling of the mold 2 during the mold changing process, saving manpower and improving the efficiency of mold changing.
