[0041] Referring to Figures 1-4 A wiring terminal production mold, comprising a main assembly 1, the main assembly 1 comprises: a bottom plate 11, the top of which is provided with a lower mold 12; the bottom plate 11 and the lower mold 12 are provided with a fixing assembly 2, the fixing assembly 2 comprises: an edge block 21, which is symmetrically and fixedly connected to the top of the bottom plate 11; a through slot 211, which is symmetrically opened in the top of the edge block 21; a cavity 22, which is opened in the edge block 21; a limiting block 23, which is slidingly connected to the inside of the edge block 21; a sliding rod 24, one end of which is fixedly connected to the front side wall of the limiting block 23, and the other end penetrates the outside of the edge block 21, the sliding rod 24 is slidingly connected with the edge block 21; a pull rod 241, which is fixedly connected to one end of the sliding rod 24 outside the edge block 21; a spring 25, which is fixedly connected between the limiting block 23 and the inner wall of the cavity 22, the spring 25 is sleeved on the outside of the sliding rod 24; a fixed block 26, which is symmetrically and fixedly connected to the outside of the rebound assembly 3 of the main assembly 1; a limiting groove 27, which is symmetrically opened in the front side wall of the fixed block 26. The limiting block 23 is symmetrically and fixedly connected with a sliding block 231 on both sides, the inner side wall of the cavity 22 is symmetrically provided with a sliding groove 232, and the sliding block 231 is slidingly connected in the sliding groove 232. The sliding rod 24 is slidingly connected with a connecting plate 242 outside, the connecting plate 242 is located between the edge block 21 and the pull rod 241, and the front side wall of the connecting plate 242 is fixedly connected with a handle 243.

[0042] In use, the staff first pull the two sides of the pull rod 241, pull rod 241 with the slide bar 24 moves, limit block 23 retracted cavity 22, and compression spring 25, at this time the lower die 12 two sides of the fixed block 26 inserted into the slot 211, at this time the lower die 12 between the edge block 21, loosen the pull rod 241, spring 25 after the deformation of the elastic force will limit block 23 to the cavity 22 outside the pop, limit block 23 inserted into the limit slot 27, the realization of the fixed block 26 limit, so that the staff only need to pull the pull rod 241, and then insert the lower die 12 can realize the lower die 12 fixed, more convenient and fast. Will be prepared metal plate or coiled material placed on the lower die 12, punch the punch under the action of the lower die 12, on the metal material blanking operation, the material according to the shape and size of the die cutting, get the terminal preliminary profile, stamping is completed, the shaped terminal from the lower die 12, in order to facilitate subsequent processing. When the staff need to remove the lower die 12, the staff pull the pull rod 241, limit block 23 from the limit slot 27 and retracted inside the cavity 22, at this time the fixed block 26 is not limited, lift the lower die 12 can be removed. Limit block 23 in the movement of the two sides of the slider 231 in the slide groove 232 sliding, the slider 231 and the slide groove 232 on the movement of the limit block 23 is oriented limit, increase the stability of the limit block 23 at the same time, avoid the limit block 23 from the cavity 22, thus affecting the firmness of the fixed lower die 12. The staff pull the handle 243, the handle 243 drive the connecting plate 242 to the front side, the connecting plate 242 drive the two sides of the slide bar 24 at the same time stretch out the edge block 21, at this time the two sides of the limit block 23 retracted cavity 22 inside, convenient to control both sides of the pull rod 241, thereby increasing the convenience of installation or disassembly of the lower die 12.

[0043] Example two

[0044] According to the basis of example one increases the auxiliary function.

[0045] Reference Figures 1-4 , the limit block 23 has a slope. The edge block 21 distance equal to the width of the lower die 12. The bottom plate 11 is provided with rebound assembly 3, the rebound assembly 3 includes: groove 31, open in the top of the bottom plate 11; spring 32, symmetrically and fixedly connected to the top of the groove 31; elastic plate 33, fixedly connected to the top of the spring 32.

[0046] The slope on the top side of the limiting block 23 enables the worker to fix the lower mold 12 without pulling the pull rod 241 in advance: the worker directly inserts the fixing block 26 into the through slot 211 on both sides, and the bottom of the fixing block 26 contacts the slope on the limiting block 23 to push the limiting block 23 into the cavity 22, at this time, the spring 25 is compressed, when the bottom of the fixing block 26 contacts the bottom surface of the through slot 211, at this time, the limiting slot 27 and the limiting block 23 are in the same horizontal line, the spring 25 directly pops the limiting block 23 into the limiting slot 27 to complete the automatic limiting of the fixing block 26, thereby improving the convenience when installing the lower mold 12. The width of the lower mold 12 is equal to the distance between the side blocks 21, which facilitates the accuracy when the fixing block 26 is inserted into the through slot 211, and facilitates the quick fixing of the lower mold 12. When the lower mold 12 is installed on the top of the bottom plate 11, at this time, the bottom of the lower mold 12 pushes the elastic plate 33 into the groove 31, and the spring 32 is compressed, when the worker pulls the pull rod 241 or the handle 243 to release the limiting of the fixing block 26, the spring 32 pops up the elastic plate 33, at this time, the lower mold 12 is pushed up by a distance, which facilitates the worker to disassemble the lower mold 12 from the bottom plate 11.
