[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] The present invention provides the following preferred embodiments:

[0031] Example 1, as Figures 1-7 As shown, a mold with a quick-change upper mold function includes a base plate 1 and a vertical plate 2, as well as a lower mold plate 5, a quick-change mechanism, a pressing mechanism and a clamping mechanism.

[0032] The lower template 5 is fixed above the base plate 1.

[0033] The quick-change mechanism includes an upper template 3 and two quick-release components. The upper template 3 is positioned above the lower template 5, and the two quick-release components are installed on one side of the upper template 3. The quick-change mechanism achieves the purpose of quick replacement by quickly locking and disassembling the two quick-release components.

[0034] The pressing mechanism includes a pressing plate 4 and a lifting assembly. The lifting assembly is located above the base plate 1, and the pressing plate 4 is installed above the lifting assembly. The pressing mechanism drives the pressing plate 4 to move up and down through the lifting assembly, thereby driving the clamping mechanism and the upper template 3 to move together.

[0035] The clamping mechanism includes a pushing component and two fixing components. The pushing component is fixedly installed above the lower pressure plate 4, and each fixing component is set between the upper template 3 and the lower pressure plate 4. The clamping mechanism drives the two fixing components to clamp the upper template 3 through the pushing component, thereby enhancing the stability of the upper template 3.

[0036] like Figures 1-7 As shown, the lifting assembly includes a first cylinder 6, a connecting plate 7, two sliding rods 8, and two sliding sleeves 9. The first cylinder 6 is fixedly installed above the base plate 1. The connecting plate 7 is installed at the output end of the first cylinder 6 and is fixedly installed below the lower pressure plate 4. Both sliding sleeves 9 are installed on the lower pressure plate 4. The two sliding rods 8 are slidably disposed inside one sliding sleeve 9, and the bottom end of each sliding rod 8 is connected to the base plate 1.

[0037] When stamping is performed, the workpiece to be processed is placed into the lower template 5, and the first cylinder 6 retracts to drive the connecting plate 7 to descend. Since the connecting plate 7 is fixedly connected to the lower pressure plate 4, the lower pressure plate 4 is driven to descend by the connecting plate 7. When the connecting plate 7 descends, it will drive the upper template 3 to descend together through the quick change mechanism, and cooperate with the lower template 5 to complete the stamping of the workpiece.

[0038] like Figures 1-7As shown, each quick-release assembly includes a first connecting post 10, a second connecting post 11, a connecting groove 12, a sliding sleeve 13, a spring 14, an annular stop 15, a sliding groove 16, an annular groove 19, multiple circular grooves 17, and multiple balls 18. The first connecting post 10 is fixedly installed on one side of the connecting plate 7. The connecting groove 12 is opened at one end of the first connecting post 10. The sliding groove 16 is opened on the outer wall surface of the first connecting post 10. The annular stop 15 is slidably disposed inside the sliding groove 16. The sliding sleeve 13 is disposed on the outer wall of the annular stop 15. The spring 14 is disposed inside the sliding groove 16, and the two ends of the spring 14 are respectively connected to one side of the annular stop 15 and the sliding groove 16. The second connecting post 11 is slidably disposed inside the connecting groove 12. Multiple circular grooves 17 are all opened on the inner wall of the first connecting post 10. Each ball 18 is movably disposed in one circular groove 17. The annular groove 19 is opened on the outer wall of the second connecting post 11, and the bottom end of each ball 18 is engaged inside the annular groove 19.

[0039] It should be noted that the thickness of the circular groove 17 is less than the diameter of the ball 18, and the distance between the inner wall of the end of the sliding sleeve 13 away from the spring 14 and the sliding groove 16 is less than the diameter of the ball 18. That is, when the sliding sleeve 13 drives the annular block 15 to move closer to the spring 14, the sliding sleeve 13 can still limit the ball 18, so that the ball 18 will not completely detach from the circular groove 17.

[0040] When the upper template 3 is damaged and needs to be replaced, the two fixed components are first moved away from each other by pushing the component, thereby unlocking the upper template 3. Then, the worker holds the sliding sleeve 13 on the outer wall of the first connecting post 10 and pulls it away from the end of the second connecting post 11. This causes the annular abutment 15 to move in the same direction inside the sliding groove 16, compressing the spring 14. This allows the second connecting post 11 to enter the connecting groove 12 inside the first connecting post 10. When the second connecting post 11 enters, it will press against the ball bearing 18 and move towards the end closer to the sliding sleeve 13. At the same time, due to the setting of the sliding sleeve 13, The ball bearing 18 can be limited so that it does not completely detach from the circular groove 17. When the second connecting post 11 is fully inserted into the connecting groove 12 inside the first connecting post 10, the annular groove 19 is moved to one side of the circular groove 17. At this time, the sliding sleeve 13 is released, and the spring 14 drives the sliding sleeve 13 to reset, thereby driving the annular block 15 to reset and press the ball bearing 18 so that one end of the ball bearing 18 is stuck inside the annular groove 19, limiting the second connecting post 11, thereby fixing the second connecting post 11 inside the first connecting post 10, achieving the effect of quick installation of the upper template 3.

[0041] When it is necessary to remove the upper template 3, the sliding sleeve 13 is manually held and pulled away from the end away from the second connecting column 11, so that the annular block 15 is moved away from the top of the circular groove 17, and the second connecting column 11 is pulled out from the inside of the connecting groove 12, thereby removing the upper template 3.

[0042] like Figures 1-7 As shown, the pushing assembly includes a vertical plate 32, a second cylinder 20, a push plate 21, and two first racks 22. The vertical plate 32 is fixed above the lower pressure plate 4. The second cylinder 20 is located on one side of the vertical plate 32. The push plate 21 is fixed at the output end of the second cylinder 20. The two first racks 22 are respectively located on both sides of the push plate 21. After the upper template 3 is replaced, the push plate 21 is pushed towards the end closer to the upper template 3 by the second cylinder 20, which drives the two first racks 22 to move towards the end closer to the upper template 3. Since each first rack 22 is meshed with a first gear 23, each first gear 23 rotates from the outside to the inside.

[0043] like Figures 1-7 As shown, each fixing component includes a first gear 23, a second gear 24, a connecting shaft 25, a second rack 27, a connecting rod 28, and a locking block 29. The connecting shaft 25 is rotatably disposed above the lower pressure plate 4. The first gear 23 and the second gear 24 are both fixed to the outer wall of the connecting shaft 25. The first gear 23 and the first rack 22 mesh with each other, and the second rack 27 and the second gear 24 mesh with each other. The connecting rod 28 is fixedly disposed at one end of the second rack 27. Each locking block 29 is disposed at the end of the connecting rod 28 away from the second rack 27. The second rack 27 is slidably disposed above the lower pressure plate 4.

[0044] When the first gear 23 rotates from the outside to the inside, since both the first gear 23 and the second gear 24 are fixedly connected to the connecting shaft 25, the connecting shaft 25 is driven to rotate. In addition, the first gear 23 and the first rack 22 mesh with each other, and the second rack 27 and the second gear 24 mesh with each other, thereby driving the second rack 27 to slide away from the top of the lower pressure plate 4 towards the end away from the vertical plate 2. Furthermore, the connecting rod 28 and the locking block 29 drive the locking block 29 to disengage from the locking groove 30, thereby removing the upper template 3.

[0045] like Figures 1-7 As shown, two slots 30 are provided on both sides of the upper template 3, and each locking block 29 engages with one slot 30. The two locking blocks 29 enter the slots 30 on both sides of the upper template 3 respectively to provide overall support for the upper template 3. After the upper template 3 is installed, the stability of the clamping mechanism is improved, thereby improving the stability of the upper template 3 installation and enhancing the stability of the upper template 3 when processing the workpiece, ensuring the smooth progress of the stamping process.

[0046] like Figures 1-7As shown, two sliding grooves 31 are provided on one side of the vertical plate 2, and each first connecting column 10 is slidably disposed in one sliding groove 31. The two sliding grooves 31 serve to avoid each other.
