[0015] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 5 It can be seen that a mold capable of quickly replacing male and female molds includes a bottom plate 1 and a top plate 2, a plurality of guide pillars 3 are provided between the bottom plate 1 and the top plate 2, a lower fixing block 4 and an upper fixing block 5 are respectively installed on the bottom plate 1 and the top plate 2, a female mold 6 is detachably installed in the lower fixing block 4, and a male mold 7 is detachably installed in the upper fixing block 5, and a limiting mechanism is provided in the lower fixing block 4 and the upper fixing block 5, which limits the position of the female mold 6 or the male mold 7;

[0017] The limiting mechanism includes a slider 8 slidingly arranged in the upper fixed block 5 or the lower fixed block 4, a plurality of spaced limiting plates 9 extending from the side of the slider 8, and a plurality of spaced tooth plates 10 extending from both sides of the punch 7 and the die 6. The tooth plates 10 cooperate with the limiting plates 9 to complete the limiting of the punch 7 or the die 6.

[0018] When the utility model is used,

[0019] Assemble the mold. During assembly, place the die 6 and punch 7 into the lower fixed block 4 and the upper fixed block 5. The limiting mechanism limits them so that the assembly can be completed quickly. Similarly, when inspecting the die 6 and punch 7, the limiting mechanism can be operated to quickly remove the punch 7 and die 6 without removing the entire mold. This can greatly reduce the time used for inspection and maintenance, avoid long-term equipment shutdown, and ensure production progress.

[0020] In this mold, the upper fixed block 5 and the lower fixed block 4 have the same structure. A sink groove 11 is provided on the lower fixed block 4 and the upper fixed block 5. Slide grooves 12 are provided on both sides of the sink groove 11. The slider 8 slides in the slide groove 12. A hydraulic cylinder 13 is provided on the outside of the lower fixed block 4 and the upper fixed block 5. The hydraulic cylinder 13 drives the slider 8 to slide. A transverse groove 14 is provided on the side of the punch 7 and the die 6 above the tooth plate 10, and the limit plate 9 extends into the transverse groove 14.

[0021] The hydraulic cylinder 13 drives the slider 8 to slide, so that the positions of the limit plate 9 and the tooth plate 10 are staggered or overlapped with each other. When the limit plate 9 and the tooth plate 10 are staggered, the die 6 and the punch 7 can be taken out. When the limit plate 9 and the tooth plate 10 overlap in the vertical direction, the limit plate 9 plays a limiting role on the tooth plate 10, fixing the die 6 in the lower fixed block 4 and the punch 7 in the upper fixed block 5. Since the number of limit plates 9 and tooth plates 10 is large and evenly distributed, a large force can be applied to the die 6 or the punch 7, so that it is stably fixed in the lower fixed block 4 or the upper fixed block 5, ensuring stability during processing.

[0022] Compared with the prior art, the utility model has the following beneficial effects: a limiting mechanism is set in the mold to limit the male and female molds, so that the positioning and installation between them and the fixed block can be quickly completed, the operation is simple, the maintenance efficiency is greatly improved, and the processing progress is guaranteed.

[0023] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of protection of the technical solution of the utility model.
