[0025] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] The utility model provides a stamping die for automobile parts which is easy to assemble.

[0028] Example 1:

[0029] like Figure 1-4 As shown, it includes two fixing seats 1, a lower mold 2 and an upper mold 3. The two fixing seats 1 are respectively fixed on the workbench of the stamping device and the connecting seat at the end of the hydraulic cylinder piston rod above. One side of the two fixing seats 1 is respectively provided with a groove 11 adapted to the lower mold 2 and the upper mold 3. Figure 2As shown, the lower mold 2 and the upper mold 3 are respectively slidably connected to the grooves 11 on the two fixed seats 1, and the interior of the groove 11 is fixedly connected to a first spring 12, and the end of the first spring 12 is fixedly connected to a support plate 13, and the support plate 13 is used to support the lower mold 2 or the upper mold 3. Both sides of the inner wall of the groove 11 are provided with a slide groove 14, and the interior of the slide groove 14 is slidably connected to a card block 5, and one side of the card block 5 is provided with a slope angle 51. One side of the card block 5 is fixedly connected to a second spring 15, and one end of the second spring 15 is in conflict with a side wall of the slide groove 14. , can support the card block 5, and both sides of the lower mold 2 and the upper mold 3 are provided with a card slot 4. The lower mold 2 is placed in the groove 11, and the support plate 13 supports the lower mold 2. By pressing the lower mold 2 downward, the first spring 12 contracts, and the bottom of the lower mold 2 conflicts with the slope angle 51 of the card block 5, so that the card block 5 slides toward the inside of the slide groove 14. When the card slot 4 corresponds to the card block 5, the second spring 15 rebounds and pushes the card block 5 so that it is clamped in the card slot 4, thereby achieving the purpose of fixing the lower mold 2. The fixing principle of the upper mold 3 is the same.

[0030] Preferably, Figure 3 As shown, a chamfer 17 is provided at the edge of the entrance of the groove 11 to expand the size of the entrance of the groove 11 and play a guiding role, thereby facilitating the alignment of the lower mold 2 or the upper mold 3 with the groove 11.

[0031] Preferably, Figure 3 and Figure 5 As shown, through holes 16 that pass through the slide groove 14 are provided on both sides of the fixing seat 1, and a limiting screw 53 is inserted inside the through hole 16. A threaded hole 52 is provided on one side of the clamping block 5, and the limiting screw 53 is threadedly connected in the threaded hole 52. The end of the limiting screw 53 conflicts with the side wall of the fixing seat 1, so that the clamping block 5 can be limited, so that the part of the clamping block 5 with the slope angle 51 protrudes in the groove 11, avoiding the protrusion of the part without the slope angle 51, resulting in the problem that the clamping block 5 cannot slide into the slide groove 14 when the lower mold 2 presses down the clamping block 5.

[0032] Example 2:

[0033] like Figure 6As shown, on the basis of Example 1, it also includes a positioning block 6, and a connecting groove 61 is opened on one side of the positioning block 6. The positioning block 6 can be sleeved on the surface of the limiting screw 53 through the connecting groove 61. When the lower mold 2 and the upper mold 3 are disassembled, the upper mold 3 is lowered, so that the first spring 12 contracts, and the upper mold 3 and the lower mold 2 respectively push the corresponding blocking blocks 5 into the sliding groove 14. At this time, the positioning block 6 is sleeved on the surface of the limiting screw 53, so that the blocking block 5 cannot be pushed out of the sliding groove 14 by the second spring 15. At this time, the upper fixed seat 1 is raised, and the upper mold 3 will slide out of the groove 11 of the upper fixed seat 1. At this time, the first spring 12 in the lower fixed seat 1 will push the lower mold 2 and the upper mold 3 to rise, and the lower mold 2 and the upper mold 3 can be moved down.

[0034] The working principle of the utility model is as follows: the two fixing seats 1 are respectively fixed on the workbench of the stamping device and the connecting seat of the piston rod end of the upper hydraulic cylinder. When in use, the lower mold 2 and the upper mold 3 are both placed on the top of the fixing seat 1 on the workbench, so that the bottom of the lower mold 2 is inserted into the groove 11 of the fixing seat 1 on the workbench, and the support plate 13 in the fixing seat 1 on the workbench supports the lower mold 2. Then the hydraulic cylinder is extended to make the upper fixing seat 1 descend, and the groove 11 of the upper fixing seat 1 is sleeved on the upper mold 3, and then continue to descend. At this time, the lower mold 2 and the upper mold 3 respectively apply force to the corresponding clamping block 5, so that the second spring 15 is compressed, so that the clamping block 5 shrinks into the slide groove 14, so that the lower mold 2 and the upper mold 3 continue to slide into the groove 11. When the clamping slot 4 corresponds to the clamping block 5, the second spring 15 rebounds, so that the clamping block 5 enters the clamping slot 4, thereby installing and fixing the lower mold 2 and the upper mold 3.

[0035] When disassembling and replacing the mold, lower the upper fixed seat 1 so that the lower mold 2 and the upper mold 3 slide in the groove 11, and push the block 5 into the slide 14. At this time, the end of the limiting screw 53 is fixed to the fixed seat 1, and then the positioning block 6 is put on the outer surface of the limiting screw 53 so that the end of the limiting screw 53 conflicts with the positioning block 6, thereby fixing the block 5 in the slide 14. At this time, raise the upper fixed seat 1, and the upper mold 3 will be disengaged from the upper fixed seat 1, and the first spring 12 in the lower fixed seat 1 will rebound, pushing the lower mold 2 and the upper mold 3 upward, so that the lower mold 2 and the upper mold 3 can be removed, and then moved down to replace the new mold.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. When installing the lower mold 2 and the upper mold 3, place both the lower mold 2 and the upper mold 3 on the top of the fixed base 1 on the workbench, so that the bottom of the lower mold 2 is inserted into the groove 11 of the fixed base 1 on the workbench, and then extend the hydraulic cylinder to lower the upper fixed base 1. When it drops to a certain height, the clamping block 5 is inserted into the clamping groove 4 to complete the installation of the lower mold 2 and the upper mold 3. The operation is simple, thereby achieving the purpose of facilitating the installation of the mold.

[0038] 2. By setting a limiting screw 53, the limiting screw 53 is threadedly connected to the threaded hole 52 on the side of the block 5. After the end of the limiting screw 53 contacts the side of the fixing seat 1, the block 5 can be limited, so that the block 5 protrudes from the groove 11 only at the part with the slope angle 51, thereby ensuring that when the lower mold 2 or the upper mold 3 applies force to the block 5, the block 5 can smoothly enter the slide groove 14. The structure is simple and the reliability is improved.

[0039] 3. When removing the lower mold 2 and the upper mold 3, lower the upper mold 3 so that the upper mold 3 contacts the lower mold 2, and continue to press the lower mold 2 downward. At this time, the clamping block 5 will slide to the inside of the slide groove 14, and the end of the limiting screw 53 will be away from the side wall of the fixed seat 1. At this time, the positioning block 6 can be sleeved on the outer surface of the limiting screw 53 to position the clamping block 5, so that the clamping block 5 cannot be pushed out of the slide groove 14 by the second spring 15, and then the upper fixed seat 1 is raised. The upper mold 3 will slide out of the groove 11 of the upper fixed seat 1, and the first spring 12 in the lower fixed seat 1 will push the lower mold 2 and the upper mold 3 to rise. At this time, the lower mold 2 and the upper mold 3 are not fixed, so the lower mold 2 and the upper mold 3 can be moved down, thereby achieving the purpose of easy disassembly.
