[0027] The design of stamping process for automobile cover parts is to determine the sequence of drawing, trimming, punching, flanging, shaping and other processes and the specific content of each process according to the product structure shape and technical requirements. In the prior art, the design and development of mold tooling generally completes the trimming and shaping process. For the existing mold tooling, due to the corresponding transmission relationship established between the upper mold and the lower tool, the two are synchronized relative to each other to complete the trimming and shaping of the workpiece to be processed. However, due to the complex transmission structure between the upper mold and the lower tool, a series of problems will arise. For example, due to the large number of matching parts in the transmission structure, the transmission chain error is large, the processing accuracy is low; the manufacturing cost is high; the maintenance is difficult, etc.

[0028] The invention provides a processing mold.

[0029] See also Figures 1 to 3 When the upper mold 21 moves from top to bottom, the processing mold 100 is in Figure 1 state, Figure 2 state, Figure 3 In one embodiment of the present invention, the processing mold 100 includes a lower mold assembly 1 and an upper mold assembly 2, the lower mold assembly 1 includes a lower mold 11, a lower tool 12 and a lower pressure plate 13, the lower pressure plate 13 is movably installed on the lower mold 11 along the up and down direction, and is used to carry the workpiece to be processed; the lower tool 12 is fixedly installed on the lower mold 11 and is located on one side of the lower pressure plate 13, so that when the lower pressure plate 13 carries the workpiece to be processed and moves downward, the workpiece to be processed is shaped; the upper mold assembly 2 is arranged on the lower mold assembly 1 Above, the upper mold assembly 2 includes an upper mold 21, an upper tool 22 and an upper pressing plate 23, the upper mold 21 has a movable stroke in the up and down directions; the upper tool 22 is fixedly installed on the upper mold 21, so as to trim the workpiece to be processed when the upper mold 21 moves downward, and it is located on the side of the lower tool 12 away from the lower pressing plate 13; the upper pressing plate 23 is movably installed along the up and down directions on the side of the upper mold 21 toward the lower mold assembly 1, so as to clamp or release the workpiece to be processed together with the lower pressing plate 13.

[0030] In the prior art, the upper pressing plate 23 and the lower pressing plate 13 jointly clamp the workpiece to be processed. Since the lower pressing plate 13 is fixedly set on the lower mold 11, the workpiece to be processed is finally kept in one position. Therefore, the lower tool 12 needs to move upward to approach the workpiece to be processed to process the workpiece. Therefore, in the process of the upper mold 21 descending, the downward movement of the lower mold 11 is converted into the upward movement of the lower tool 12, wherein the upper mold 21 and the lower tool 12 are both movably set along the up and down directions. The technical solution of the present invention is achieved by improving the design of the upper mold 21 component 2 and the lower mold component 1. The most important thing is that the lower pressing plate 13 is changed to be movable in the up and down direction, and the lower tool 12 is fixedly set on the lower mold 11. When the upper mold 21 moves in the up and down direction, it will drive the upper pressing plate 23 to move. When the upper mold 21 moves downward, the upper pressing plate 23 will also move downward. First, it clamps the workpiece to be processed together with the lower pressing plate 13 to keep the workpiece fixed relative to the lower pressing plate 13. At this time, the upper tool 22 and the lower tool 12 maintain a certain distance, and the workpiece to be processed passes between the upper tool 22 and the lower tool 12. At this time, the upper mold 21 continues to move downward, and the upper pressing plate 23 pushes the lower pressing plate 13 downward, and the upper tool 22 and the lower tool 12 gradually approach to cut off the workpiece to be processed, completing the trimming process. The upper mold 21 further drives the upper pressing plate 23 downward, and the upper pressing plate 23 further pushes the lower pressing plate 13 and the workpiece to be processed downward, so that the workpiece to be processed will also move downward further, so that part of the workpiece to be processed is clamped between the upper pressing plate 23 and the lower tool 12, and the shaping process is completed for part of the workpiece to be processed. In the structure of the present application, the connection between the movement of the upper mold 21 and the movement of the lower tool 12 is cancelled, and part of the transmission structure in the prior art is omitted. By arranging the lower pressing plate 13 to move, the workpiece to be processed and the lower tool 12 can move relative to each other, thereby completing the trimming and shaping process. In this processing mold 100, the internal structure of the mold is simplified, so as to achieve the effect of improving processing accuracy, reducing manufacturing costs, and reducing maintenance difficulty.

[0031] Since the lower die 11 is fixedly arranged, in order to make the lower pressing plate 13 relatively movable relative to the lower die 11, the processing mold 100 also includes a driving assembly 3, and the driving assembly 3 includes a first driving member 31, which is arranged between the lower die 11 and the lower pressing plate 13, and the first driving member 31 needs to meet the following requirements: the lower die 11 can be moved in the up and down direction, and when the external force applied by the upper die assembly 2 to the lower pressing plate 13 is withdrawn, the first driving member 31 can restore the lower pressing plate 13 to the initial position, which is used to receive the processed parts, and when the lower pressing plate 13 is subjected to the downward pressure again, it moves downward again. Therefore, the first driving member 31 can be set to a leaf spring, a cylinder, etc. Since the cylinder has the characteristics of adjustable pressure, stable transmission, and can remain stable in one position relative to the leaf spring, the first driving member 31 generally selects a nitrogen cylinder. Since the weight of the lower pressing material is heavy, the first driving member 31 is provided with a plurality of, and in order to transmit smoothly, the first driving member 31 is provided with a plurality of intervals in the horizontal direction.

[0032] In order to ensure the shaping quality of the workpiece, after the workpiece is clamped and shaped by the upper pressing plate 23 and the lower tool 12, it is necessary to continuously apply pressure to the workpiece between the upper pressing plate 23 and the lower tool 12 for a period of time to ensure the shaping quality. In order to achieve the above effect, the driving assembly 3 also includes a plurality of second driving members 32, and the plurality of second driving members 32 are arranged between the upper mold 21 and the upper pressing plate 23, so that the upper pressing plate 23 can move relative to the upper mold 21. During the downward movement of the upper die 21, the upper die 21 moves downward first, and the upper blank plate 23 is fixed relative to the upper die 21, and no relative displacement occurs. After the upper blank plate 23 and the lower blank plate 13 clamp the workpiece together, the workpiece needs to be moved downward to complete trimming and shaping, so the downward force on the workpiece needs to be greater than the upward force, so the sum of the forces of the second driving members 32 acting on the upper blank plate 23 needs to be greater than the sum of the forces of the first driving members 31 acting on the lower blank plate 13. Only in this way can the lower blank plate 13 and the workpiece move downward. When the upper pressing plate 23 and the lower tool 12 jointly clamp the workpiece to be processed and start shaping, the compression stroke of the first driving member 31 reaches the maximum, the lower pressing plate 13 and the workpiece to be processed reach the lowest position, and the second driving member 32 has not yet reached the maximum compression stroke. At this time, the upper mold 21 continues to descend, while the position of the upper pressing plate 23 remains unchanged. The second driving member 32 continues to compress, and the pressure inside it is transmitted to the upper pressing plate 23 to continue shaping the workpiece to be processed until the compression stroke of the upper pressing plate 23 reaches the maximum, the shaping process is completed, and the upper mold 21 starts to ascend, and the workpiece to be processed between the two can be taken out. The second driving member 32 is also generally a nitrogen cylinder, because the driving member such as a leaf spring, when the upper pressing plate 23 and the lower tool 12 are clamped together to be processed and shaped, the first driving member 31 (the internal pressure of the nitrogen cylinder is not constant) has a greater pressure when the compression amount is greater, so as to avoid the first driving member 31 causing plastic deformation to the leaf spring and causing changes to the lowest position of the lower pressing plate 13, so the second driving member 32 is still a nitrogen cylinder. Among them, the second driving member 32 is also provided with a plurality of, and is arranged at intervals in the horizontal direction for stable transmission.

[0033] In order to drive the upper mold 21 to move in the up and down direction, the driving assembly 3 also includes a third driving member, which is drivingly connected to the upper mold 21 to drive the upper mold 21 to move in the up and down direction. The third driving member can be set as a hydraulic cylinder, and the upper mold is directly driven by the hydraulic cylinder.

[0034] In order to ensure that the upper blanking plate 23 moves only in the up-down direction relative to the upper mold 21 without horizontal displacement, and to ensure that the lower blanking plate 13 moves only in the up-down direction relative to the lower mold 11 without horizontal displacement, so as to ensure the processing accuracy, the lower mold 11, the lower blanking plate 13, the upper mold 21, and the upper blanking plate 23 are all provided with guide holes 4, and the processing mold 100 also includes a plurality of guide rods 5, the same guide rod 5 penetrates the two guide holes 4 corresponding to the lower mold 11 and the lower blanking plate 13, and the same guide rod 5 penetrates the two guide holes 4 corresponding to the upper mold 21 and the upper blanking plate 23.

[0035] In the process of processing the workpiece, it is necessary to first clamp the workpiece at the same time with the upper pressing plate 23 and the lower pressing plate 13, fix the workpiece, and then trim and shape the workpiece, so the distance between the upper pressing plate 23 and the lower pressing plate 13 in the up-down direction is less than the distance between the upper tool 22 and the lower tool 12 in the up-down direction. When the upper pressing plate 23 and the lower pressing plate 13 are clamping the workpiece together, there is still a certain distance between the upper tool 22 and the lower tool 12. The unclamped part of the workpiece passes through the gap between the upper tool 22 and the lower tool 12. When the upper die 21 continues to descend, the upper tool 22 and the lower tool 12 gradually approach each other, and finally the upper tool 22 and the lower tool 12 partially overlap in the horizontal direction to complete the trimming of the workpiece. If the distance between the upper pressing plate 23 and the lower pressing plate 13 in the up-down direction is greater than the distance between the upper tool 22 and the lower tool 12 in the up-down direction. Then, when the upper die 21 descends, the trimming of the workpiece is completed first and then clamped. When the workpiece abuts against one of the upper tool 22 and the lower tool 12, since the workpiece is not fixed, the movement of the workpiece relative to the tool will cause the workpiece to be shifted, resulting in a large processing error.

[0036] After the upper cutter 22 and the lower cutter 12 are cut at the same time, the upper die 21 will continue to move downward, and the upper cutter 22 is fixedly set on the upper die 21, so the upper cutter 22 will also continue to move downward. If the upper cutter 22 and the lower cutter 12 are set relative to each other in the vertical direction, then the lower cutter 12 will abut against the upper cutter 22, hindering the upper die 21 from continuing to move downward, and the shaping process cannot be completed. Therefore, the upper cutter 22 and the lower cutter 12 are staggered in the horizontal direction, and one side of the upper cutter 22 and one side of the lower cutter 12 are set correspondingly in the vertical direction. There is no or very little gap between the upper cutter 22 and the lower cutter 12 in the horizontal direction, so as to ensure that the workpiece to be processed can be cut, wherein the cutting edges of the upper cutter 22 and the lower cutter 12 are acute angles. And the lower cutter 12 corresponds to the upper press plate 23 in the vertical direction. In this way, the lower cutter 12 and the upper press plate 23 can jointly clamp the workpiece to be processed to achieve the shaping of the workpiece to be processed.

[0037] In order to shape the workpiece to be processed into an inclined surface, the upper pressing plate 23 has a first shaping surface 231 which is inclined toward the lower tool 12. A side wall of the upper tool 22 corresponding to the lower tool 12 forms a groove with the first shaping surface 231, and the groove is for the lower tool 12 to extend into. The lower tool 12 has a second shaping surface 121, and the second shaping surface 121 is inclined and opposite to the first shaping surface 231 in the up and down directions.

[0038] Since the upper tool 22 and the lower tool 12 will be worn to a certain extent after long-term use, the sharpness of the cutting edge will decrease, and the shaping accuracy of the workpiece will also decrease, so the tool needs to be replaced. The corresponding upper tool 22 can be detachably installed on the upper mold 21, and the lower tool 12 can be detachably installed on the lower mold 11. The corresponding upper mold 21 and the lower mold 11 are also provided with corresponding positioning parts for installing and positioning the tools. Moreover, compared with the setting form in the prior art, the transmission structure between the upper mold 21 and the lower tool 12 is omitted, and the freed space is convenient for replacing the upper tool 22 and the lower tool 12. At the same time, the maintenance of the transmission structure is also omitted.

[0039] Since the trimming of the workpiece to be processed is completed during the process of the upper mold 21 closing the mold toward the lower mold 11, the waste cut from the workpiece to be processed exists inside the processing mold 100. In the processing mold 100 of this embodiment, since the transmission structure is omitted, the position where the transmission structure is originally installed forms a cavity 6, and the cavity 6 is located at the lower mold 11. The cavity 6 is arranged on the side of the lower cutter 12 that is away from the lower pressing plate 13 in the horizontal direction. The processing mold 100 also includes a slide plate for receiving the waste. The slide plate is slidably installed in the cavity 6 and has a movable stroke that partially slides outside the cavity 6. After the processing mold 100 has been used for a period of time, the slide plate is pulled out, and the waste on the slide plate is poured out to realize the cleaning of the waste generated by the processing mold 100, which is easy to operate. However, due to the existence of the transmission structure, the technical solution in the prior art will also make the cleaning of the waste more difficult than this embodiment.

[0040] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
