[0037] In order to reduce the difficulty of die cutting maintenance, it is possible to simply and conveniently achieve the die cutting and die matching requirements close to zero clearance, such as Figure 1-Figure 3 As shown, the utility model provides a zero gap adjustment structure. The zero gap adjustment structure comprises a mold frame 1, an inclined slide block 2, a knife mold 7 and a position adjustment component.

[0038] Among them, an oblique mold cavity 11 is opened on the mold frame 1, and the bottom surface 111 of the oblique mold cavity 11 is set obliquely downward along the first direction. The oblique slider 2 has a matching surface set obliquely upward along the first direction, and the oblique slider 2 is set in the oblique mold cavity 11, and the matching surface is slidably matched with the bottom surface 111 of the oblique mold cavity 11. The knife die 7 is slidably set on the end of the oblique slider 2 away from the matching surface, and the knife die 7 is located in the oblique mold cavity 11; the position adjustment component is set on the mold frame 1, and the position adjustment component is transmission-connected with the oblique slider 2, and the position adjustment component can push the oblique slider 2 to slide relative to the mold frame 1 along the first direction, so as to adjust the height of the knife die 7 under the cooperation of the matching surface and the bottom surface 111 of the oblique mold cavity 11, so that the knife die 7 and the end surface of the oblique mold cavity 11 are in the same horizontal plane.

[0039] Further, the inclined slider 2 includes a first slider body 21 and a second slider body 22, both of which have a mating surface, and the first slider body 21 and the second slider body 22 are surrounded to form a first gap 24 extending along the first direction, and the position adjustment component includes a first adjustment component 3 and a second adjustment component 4, the first adjustment component 3 is transmission-connected to the first slider body 21, and the second adjustment component 4 is transmission-connected to the second slider body 22. Through the above arrangement, the first adjustment component 3 and the second adjustment component 4 can be used to independently adjust the first slider body 21 and the second slider body 22 as needed, thereby improving the flexibility of adjusting the knife die 7.

[0040] Further, one side of the oblique mold cavity 11 has a first guide groove, and the first adjustment assembly 3 includes a first adjustment bolt 31 and a first adjustment block 32. The first adjustment bolt 31 is screwed to the mold frame 1, and the first adjustment block 32 is sleeved on the first adjustment bolt 31 and is located in the first guide groove. The first adjustment block 32 has a first inclined surface 321, and the first slider body 21 has a second inclined surface that cooperates with the first inclined surface 321. Rotating the first adjustment bolt 31 can drive the first adjustment block 32 to move, so as to push the first slider body 21 to slide along the first direction through the cooperation of the first inclined surface 321 and the second inclined surface. During the adjustment process, by screwing the first adjustment bolt 31, the first adjustment bolt 31 drives the first adjustment block 32 to move toward the bottom of the oblique mold cavity 11, so that under the cooperation of the first inclined surface 321 and the second inclined surface, the first slider body 21 is pushed to move along the first direction. By using the first inclined surface 321 and the second inclined surface in cooperation, the vertical movement of the first adjusting block 32 can be converted into the lateral movement of the first slider body 21 along the first direction. By adjusting the position of the first adjusting block 32 relative to the matching surface, the height position of the cutting die 7 can be adjusted.

[0041] Further, one side of the oblique mold cavity 11 has a second guide groove, and the second adjustment assembly 4 includes a second adjustment bolt 41 and a second adjustment block 42. The second adjustment bolt 41 is screwed to the mold frame 1, and the second adjustment block 42 is sleeved on the second adjustment bolt 41 and is located in the second guide groove. The second adjustment block 42 has a third inclined surface 421, and the second slider body 22 has a fourth inclined surface that cooperates with the third inclined surface 421. Rotating the second adjustment bolt 41 can drive the second adjustment block 42 to move, so as to push the second slider body 22 to slide along the first direction through the cooperation of the third inclined surface 421 and the fourth inclined surface. During the adjustment process, by screwing the second adjustment bolt 41, the second adjustment bolt 41 drives the second adjustment block 42 to move toward the bottom of the oblique mold cavity 11, so that under the cooperation of the third inclined surface 421 and the fourth inclined surface, the second slider body 22 is pushed to move along the first direction. By using the third inclined surface 421 in combination with the fourth inclined surface, the vertical movement of the second adjustment block 42 can be converted into the lateral movement of the second slider body 22 along the first direction. By adjusting the position of the second adjustment block 42 relative to the matching surface, the height position of the cutting die 7 can be adjusted.

[0042] Furthermore, the knife die 7 includes a first die body 71 and a second die body 72, the first die body 71 and the second die body 72 are arranged to form a second gap opposite to the first gap 24, the first die body 71 is arranged on the first slider body 21, and the second die body 72 is arranged on the second slider body 22. When adjusting the position of the first slider body 21, the height position of the first die body 71 can be adjusted, and when adjusting the second slider body 22, the position of the second die body 72 can be adjusted. Through the above arrangement, the positions of the first die body 71 and the second die body 72 can be adjusted independently, so that the heights of the first die body 71 and the second die body 72 can be flexibly adjusted as needed. Moreover, when either of the first die body 71 and the second die body 72 is excessively worn and cannot be used, only the corresponding die body needs to be replaced, and there is no need to replace the entire knife die 7.

[0043] Furthermore, the zero clearance adjustment structure further includes a first elastic buffer assembly 5 and a second elastic buffer assembly 6. The first elastic buffer assembly 5 and the second elastic buffer assembly 6 are both arranged on the side of the oblique mold cavity 11 away from the position adjustment assembly. The first elastic buffer assembly 5 abuts against the first slider body 21, and the second elastic buffer assembly 6 abuts against the second slider body 22. After adjusting the position of the first slider body 21 and / or the second slider body 22 to exceed the appropriate position, it is only necessary to loosen the first adjustment bolt 31 and / or the second adjustment bolt 41, and under the action of the corresponding first elastic buffer assembly 5 and / or the second elastic buffer assembly 6, the corresponding first slider body 21 and / or the second slider body 22 can be pushed to reset.

[0044] Furthermore, the other side of the oblique mold cavity 11 has a first mounting groove, and the first elastic buffer assembly 5 includes a first elastic member 51 and a first mounting member 52. The first mounting member 52 is located in the first mounting groove, and one end of the first elastic member 51 abuts against the first slider body 21, and the other end of the first elastic member 51 abuts against the first mounting member 52. In the process of adjusting the position of the first slider body 21, the first elastic member 51 is compressed and in an energy storage state, and at the same time, it can limit the first slider body 21 from moving too fast, thereby ensuring the accuracy of the adjustment.

Specifically, after the position of the cutting die 7 is adjusted, the relative position between the cutting die 7, the inclined slider 2 and the mold frame 1 is locked by the locking member to play a fixing role. In this embodiment, the locking member is a bolt, and the bolt passes through the first connection hole 73, the strip hole 23 and the second connection hole 12 and is connected with a nut, thereby playing a locking role. In this embodiment, the first connection hole 73, the strip hole 23 and the second connection hole 12 are all arranged in multiple numbers in a one-to-one correspondence, and multiple locking members fix the cutting die 7, the inclined slider 2 and the mold frame 1 to ensure the stability of the connection. Further, the first connection hole 73 is a stepped hole, and the head of the locking member is located in the first connection hole 73. Through the above arrangement, the head of the locking piece can be hidden without affecting the subsequent cutting process of the parts.
