[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0024] A split-type cutting die includes an upper die assembly and a lower die assembly, wherein:

[0025] The upper mold assembly includes an upper mold base 1, an upper template 2 fixedly connected to the bottom of the upper mold base 1, a cutter fixing plate 3 fixedly connected to the bottom of the upper template 2, and a mounting groove 31 for mounting a cutter assembly 4 on the bottom of the cutter fixing plate 3. The cutter assembly 4 includes a cutter 41 and a cutter holder 42, a cutter groove 421 on the bottom of the cutter holder 42, the cutter 41 being installed in the cutter groove 421, and circular grooves 422 communicating with both sides of the cutter groove 421, with fixing holes 423 on both sides of the circular groove 422. A column 411 is provided on both sides of the cutter 41 to engage with the circular groove 422, and an elastic fixing key 412 is provided on both sides of the column 411 to engage with the fixing holes 423.

[0026] The lower mold assembly includes lower mold bases 5 located on both sides. The top of the two lower mold bases 5 are fixedly connected to a lower template 6. The top of the lower template 6 is provided with a channel 61 for the plate to pass through. The bottom of the channel 51 is provided with a cutting hole 62 for the cutting tool 41 to pass through.

[0027] This utility model features a split-type cutter assembly 4, in which the cutter 41 and the cutter holder 42 are detachably connected. The cutter 41 is inserted into the circular groove 422 via a column 411 and connected to the fixing hole 423 via an elastic fixing key 412. By pressing the elastic fixing key 31 to disengage it from the fixing hole 423, the cutter 41 can be separated from the cutter holder 42, thus facilitating quick replacement of the worn cutter 41, significantly shortening the time required to replace the cutter, and increasing convenience.

[0028] Furthermore, in another embodiment, a buffer plate 7 is provided below the cutter fixing plate 3, and the four corners of the buffer plate 7 are respectively connected to the upper mold base 1 through a buffer mechanism 8.

[0029] By setting up a buffer plate 7 and a buffer mechanism 8, the upper die assembly can press down firmly on the sheet metal 8, preventing the sheet metal from shifting during the stamping process and improving the stability of the stamping process.

[0030] Furthermore, in another embodiment, the buffer mechanism 8 includes a limiting sleeve 81, which is installed inside the buffer plate 7. A connecting post 82 is inserted into the limiting sleeve 81. Slider blocks 83 are symmetrically installed at both ends of the bottom of the connecting post 82. A sliding groove 84 is opened inside the limiting sleeve 81 to slide with the slider 83. A fixing block 85 is fixedly connected to the top of the connecting post 82 through the limiting sleeve 81. The fixing block 85 is fixedly connected to the upper mold base 1. The bottom of the fixing block 85 is fixedly connected to the top of the return spring 86. The bottom of the return spring 86 is fixedly connected to the limiting sleeve 81. The connecting post 82 is disposed inside the return spring 86.

[0031] By setting up a buffer mechanism 8, when the upper mold assembly moves downward, the buffer plate 7 first contacts the plate 8. As the upper mold continues to move downward, the slider 83 at the bottom of the connecting column 82 slides down along the groove 84 inside the limiting sleeve 81. The connecting column 82 retracts into the limiting sleeve 81, and the return spring 86 between the fixing block 85 and the limiting sleeve 81 is compressed, accumulating elastic potential energy. During this process, the compression force of the return spring 86 causes the buffer plate 9 to press against the plate, preventing its displacement. At the same time, the spring absorbs the impact force, buffering and damping. After the stamping is completed, the upper mold assembly moves upward, and the return spring 86, which has lost pressure, returns to its original state, generating an upward restoring force. This pushes the limiting sleeve 81, causing the buffer plate 9 to move upward. The connecting column 82 returns to its initial position with the cooperation of the slider 83 and the groove 84, completing the automatic reset of the buffer plate.

[0032] Furthermore, in another embodiment, a plurality of finger grooves 32 are respectively provided on both sides of the mounting groove 31.

[0033] By setting the finger groove 32, when installing or removing the tool 41, the operator can easily press the elastic fixing key 31 through the finger groove, providing space for the operator to press and achieving the purpose of quick disassembly.

[0034] Furthermore, in another embodiment, the buffer plate 7 has a through hole 71 through which the cutting tool 41 passes.

[0035] By setting through hole 71, the tool 41 can pass smoothly through buffer plate 7 during up and down movement, ensuring the normal operation of the cutting action.

[0036] Furthermore, in another embodiment, a first guide seat 9 is fixedly connected to both sides of the bottom of the upper mold base 1, and a second guide seat 10 is fixedly connected to the top of the lower mold base 5. A guide rod 11 is fixedly connected to the second guide seat 10, and the top of the guide rod 11 is engaged with the first guide seat 9.

[0037] Through the coordinated action of the first guide seat 9, the second guide seat 10 and the guide rod 11, a precise guiding function can be achieved during the mold closing process, ensuring that the upper mold assembly and the lower mold assembly can be accurately aligned, thereby improving the assembly accuracy and working precision of the mold.

[0038] The working principle of this utility model is as follows:

[0039] The upper mold base 1 drives the upper template 2, the cutter fixing plate 3, and the cutter assembly 4 to move downwards. The guide rod 11 inserts into the first guide seat 9 to guide the mold closing and ensure precise alignment of the upper and lower mold assemblies. The cutter 41 moves downwards with the cutter fixing plate 3, extends through the through hole 71 of the buffer plate 7, and passes through the cutter hole 62 of the lower template 6, applying shearing force to the sheet material located in the channel 61 to complete the cutting action. At this time, the return spring 86 of the buffer mechanism 8 is compressed, and the buffer plate 7 absorbs the downward impact force of the upper mold assembly through the sliding cooperation between the limit sleeve 81 and the connecting column 82, avoiding rigid collision. After the cutting is completed, the upper mold base 1 drives the cutter assembly 4 to move upwards to reset, the return spring 86 releases its elastic potential energy, pushes the buffer plate 7 to rise synchronously, the guide rod 11 disengages from the first guide seat 9, and the mold returns to its initial state, waiting for the next feeding and cutting.

[0040] When it is necessary to replace the tool 41, the tool 41 is pulled out directly from the circular groove 422 of the tool holder 42. The elastic fixing key 412 is compressed and disengaged from the fixing hole 423, so that the old tool can be removed and the new tool can be installed. The positioning and fixing are completed by the insertion of the column 411 into the circular groove 422 and the engagement of the elastic key 412.
