[0001] This utility model relates to the field of punch press mold technology, and in particular to a multi-specification punch press mold suitable for aluminum plate materials. Background Technology

[0002] Punch presses are among the most common machining equipment in mechanical processing. They primarily process sheet metal, performing functions such as blanking, punching, forming, stretching, trimming, fine blanking, shaping, and extrusion. They are widely used in various fields. The working principle of a punch press involves converting the circular motion of a motor into linear motion via a crankshaft and connecting rod, applying pressure to the sheet metal to cause plastic deformation.

[0003] When existing punching dies need to be changed to different samples during use, the entire die must be disassembled and replaced with the corresponding die. It is not possible to quickly change the die for the corresponding sample, which greatly reduces the work efficiency of workers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot quickly change the die for corresponding samples, and to propose a multi-specification punching die suitable for aluminum plate materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-specification punching die suitable for aluminum plate materials, comprising a lower die, an upper die at the top of the lower die, a concave die in the middle of the lower die, two first sliders on the surface of the concave die, first grooves on both sides of the concave die, a locking tongue inside the concave die, a pull ring on the top surface of the locking tongue, a partition on one side of the pull ring, an installation groove on one side of the partition, a connecting rod at the bottom of the installation groove, a locking block at one end of the connecting rod, a movable chamber on one side of the connecting rod, a return spring on one side of the movable chamber, two second sliders on one side of the locking tongue, a fixing plate between the two second sliders, two second grooves on the surface of the fixing plate, a locking groove between the two second grooves, and a handle at the top of the locking groove.

[0006] Preferably, two first grooves are provided on the surface of the lower mold, two first sliders 13 are provided on both sides of the cavity mold, and the first sliders are mounted on the first grooves.

[0007] Preferably, two second sliders are disposed on the surface of the lower mold, two second grooves are disposed on both sides of the fixed plate, and the second sliders are installed in the second grooves.

[0008] Preferably, the slot and the latch are positioned at the same location, and the latch is installed inside the slot.

[0009] Preferably, the connecting rod is located on the surface of the latch, on the side away from the fixed plate, and inside the return spring.

[0010] Preferably, one end of the connecting rod passes through the movable cabin, and the locking block is located inside the movable cabin.

[0011] Preferably, the pull ring passes through the lower mold, one end of the partition is mounted on the pull ring, and the other end of the partition is mounted in the mounting groove.

[0012] Beneficial effects

[0013] In this invention, a concave mold is mounted on a first slide groove of a lower mold via first sliders on both sides. Two second sliders are provided on one side of the concave mold, and a fixing plate is mounted on the two second sliders via the second slide grooves on both sides. A locking tongue is provided inside the concave mold, and a pull ring is provided on the top surface of the locking tongue. One end of the pull ring passes through the concave mold. When it is necessary to change the mold shape, the pull ring can be pulled to disengage the locking tongue of the concave mold from the slot of the fixing plate. The fixing plate can then be pulled upwards by the handle to disengage it from the middle of the two second sliders. At this time, the concave mold can be pulled out from the middle of the lower mold, and a new concave mold can be placed into the lower mold and pushed into the lower mold. When the lower mold is fully mounted in the middle of the lower mold through the cooperation of the first slider and the first slide groove, the second slide grooves at both ends of the fixing plate can be mounted on the second sliders and pushed downwards. When the fixing plate is pushed downwards, the locking tongue of the concave mold will engage in the slot, thus fixing the concave mold and completing the replacement. This solves the problem of not being able to quickly change the concave mold of the corresponding sample. Attached Figure Description

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-6 A multi-specification punching die suitable for aluminum sheet materials includes a lower die 1, an upper die 2 at the top of the lower die 1, a concave die 18 in the middle of the lower die 1, two first sliders 13 on the surface of the concave die 18, first grooves 12 on both sides of the concave die 18, a locking tongue 6 inside the concave die 18, a pull ring 11 on the top surface of the locking tongue 6, a partition 14 on one side of the pull ring 11, a mounting groove 15 on one side of the partition 14, a connecting rod 10 at the bottom of the mounting groove 15, a locking block 9 at one end of the connecting rod 10, a movable chamber 7 on one side of the connecting rod 10, a return spring 8 on one side of the movable chamber 7, two second sliders 17 on one side of the locking tongue 6, a fixing plate 4 between the two second sliders 17, two second grooves 16 on the surface of the fixing plate 4, and a locking groove 3 between the two second grooves 16. The top is provided with a handle 5, two first slide grooves 12 are provided on the surface of the lower mold 1, two first sliders 13 are provided on both sides of the cavity mold 18 and the first sliders 13 are installed on the first slide grooves 12, two second sliders 17 are provided on the surface of the lower mold 1, two second slide grooves 16 are provided on both sides of the fixed plate 4 and the second sliders 17 are installed in the second slide grooves 16, the slot 3 and the locking tongue 6 are provided in the same position and the locking tongue 6 is installed inside the slot 3, the connecting rod 10 is provided on the surface of the locking tongue 6, the connecting rod 10 is provided on the side away from the fixed plate 4 and the connecting rod 10 is provided inside the return spring 8, one end of the connecting rod 10 passes through the movable chamber 7 and the locking block 9 is provided inside the movable chamber 7, the pull ring 11 passes through the lower mold 1, one end of the partition plate 14 is installed on the pull ring 11 and the other end of the partition plate 14 is installed in the mounting groove 15.

[0026] The die 18 is mounted on the first slide groove 12 of the lower mold 1 via the first sliders 13 on both sides. This allows the die 18 to be easily installed or removed from the lower mold 1 by pushing it into the lower mold 1. The first sliders 13 will slide within the first slide groove 12, thus mounting the die 18 onto the lower mold 1. Two second sliders 17 are located on one side of the die 18. The fixing plate 4 is mounted on the two second sliders 17 via the second slide grooves 16 on both sides, allowing the fixing plate 4 to move up and down. A locking tongue 6 is located inside the die 18, and a pull ring 11 is located on the top surface of the locking tongue 6. One end of the pull ring 11 passes through the die 18. When the mold shape needs to be changed, the pull ring 11 can be pulled to disengage the locking tongue 6 of the die 18 from the slot 3 of the fixing plate 4. When the pull ring 11 is pulled, the partition 14 on its surface will retract into the mounting groove 15. When the locking tongue 6 returns to its original position, the pull ring 11 will also return to its original position, allowing the partition 14 to slide out of the mounting groove 15. This will protect the return spring 8 and other components inside the die 18, preventing debris from falling into the return spring 8 and causing blockage. The fixing plate 4 is then pulled upward by the handle 5, causing it to disengage from the middle of the two second sliders 17. At this point, the die 18 can be pulled out from the middle of the lower mold 1. During the extraction, the first slider 13 will slide in the first slide groove 12 to ensure that the die 18 can be pulled out smoothly. A new die 18 is then placed into the lower mold 1 and pushed into the interior of the lower mold 1. When the lower mold 1 passes through the first slide groove 12, the first slider 13 slides in the first slide groove 12. When the slider 13 and the first slide groove 12 are fully installed in the middle of the lower mold 1, the second slide grooves 16 at both ends of the fixing plate 4 can be installed on the second slider 17 and pushed down. The fixing plate 4 will be installed on the lower mold 1 because the second slider 17 moves in the second slide groove 16. When the fixing plate 4 is pushed down, it will knock open the locking tongue 6, causing the locking tongue 6 to retract into the cavity mold 18. When the fixing plate 4 is installed, the locking tongue 6 of the cavity mold 18 will be reset by the return spring 8 inside the cavity mold 18. Since the locking tongue 6 is connected to the locking block 9 through the connecting rod 10, and the locking block 9 is installed in the movable chamber 7, the locking block 9 can reciprocate in the movable chamber 7. In this way, the locking tongue 6 is reset by the return spring 8. When the timing is right, the locking block 9 will be restricted by the movable chamber 7 to prevent the locking tongue 6 from popping out during reset, allowing the locking tongue 6 to smoothly engage in the slot 3, and the fixing plate 4 to fix the die 18 to complete the replacement. When the replacement is complete, the metal sheet can be placed between the upper mold 2 and the lower mold 1. The control system sends a signal to start the motor, which causes the slider to move downward through the piston mechanism. The slider drives the upper mold 2 to press down on the metal sheet and start processing. When the upper mold 2 presses down to a certain position, the downward pressure is further increased, causing the upper mold 2 to bend the metal sheet. Since the die 18 of the lower mold 1 is formed into a concave shape, when the upper mold 2 bends the metal sheet, the metal sheet will take on the shape of the die 18 of the lower mold 1, completing the stamping. Specific Implementation Example 2:

[0028] Reference Figure 1-6 The latch 6 can be replaced with a detachable latch 6, and two mounting brackets are provided on both sides of the detachable latch 6. The surface of the corresponding cavity 18 of the mounting bracket is provided with a fixing groove, and threaded holes are provided on the surface of the mounting bracket and the fixing groove. When installing, the two mounting brackets of the latch 6 can be aligned with the fixing groove, and fixed by inserting fixing bolts into the bolt holes of the mounting bracket and the fixing groove, so that the detachable latch 6 is bolted to the cavity 18. In this way, when the detachable latch 6 or the return spring 8 and other components inside the detachable latch 6 are damaged, the fixing bolts can be removed and the detachable latch 6 can be replaced.

[0029] In summary:

[0030] 1. A concave mold 18 is mounted on the first slide groove 12 of the lower mold 1 via first sliders 13 on both sides. Two second sliders 17 are provided on one side of the concave mold 18. A fixing plate 4 is mounted on the two second sliders 17 via second slide grooves 16 on both sides. A locking tongue 6 is provided inside the concave mold 18, and a pull ring 11 is provided on the top surface of the locking tongue 6. One end of the pull ring 11 passes through the concave mold 18. When it is necessary to change the mold shape, the pull ring 11 can be pulled to disengage the locking tongue 6 of the concave mold 18 from the slot 3 of the fixing plate 4, and the fixing plate 4 can be pulled upward by the handle 5, so that the fixing plate 4 disengages from the two second sliders 17. When the middle of block 17 is detached, the die 18 can be pulled out from the middle of the lower mold 1. The new die 18 is placed into the lower mold 1 and pushed into the interior of the lower mold 1. When the lower mold 1 is fully installed in the middle of the lower mold 1 through the cooperation of the first slider 13 and the first slide groove 12, the second slide grooves 16 at both ends of the fixing plate 4 can be installed on the second slider 17 and pushed down. When the fixing plate 4 is pushed down, the locking tongue 6 of the die 18 will be engaged in the slot 3, so that the fixing plate 4 fixes the die 18 and completes the replacement. This solves the disadvantage that the die 18 of the corresponding sample cannot be quickly replaced.
