[0013] The beneficial effects of the utility model are:

[0014] 1. This application realizes the rib punching operation by cooperating between the upper die assembly, the lower die assembly and the die core assembly to push the die insert and the punch toward each other in turn. Multiple groups of rib punching can be completed at one time, which is easy to operate and improves work efficiency.

[0015] 2. In the present application, the die insert and the punch are arranged in a punching chamber surrounded by an upper die assembly, a lower die assembly and a guide mechanism, and under the action of the die-core assembly, the die insert and the punch are limited and guided to ensure the stability of the punching.

[0016] 3. In the present application, the elastic support column will undergo elastic deformation under the action of pressure, thereby moving downward together with the upper mold assembly, and the insert block will extend into the mold core to provide mobile support for the female mold insert.

[0020] 7. In the present application, the bottom of the guide block is embedded in the fixing hole on the fixing block, which guides and supports the punch insert. At the same time, since the pressure spring is against the two ends of the pressure block and the outer sliding block, the pressure block can press the cup tube to prevent the cup tube from shaking and ensure the quality of the ribs. The pressure spring can also push the outer sliding block and the punch insert to reset after the axial guide ring is reset.

[0021] 8. The press block and the outer sliding block described in the present application are provided with limiting grooves for the press spring to extend into, which stabilizes the setting of the press spring and prevents it from accidentally falling off.

[0022] 9. In the present application, the axial guide ring, the outer slider, the punch insert and the inner insert block are all provided with inclined surfaces. During the contact and sliding process between each other, the inclined surfaces play a guiding role, and the pushing between them ensures the smooth operation of each component.

Example 2

[0043] like Figure 2-3 As shown, this embodiment is obtained by adding technical features such as a limit column 25 on the basis of the first embodiment. The remaining technical features are the same as those of the first embodiment, and the similarities are not repeated here. Among them, the difference between this embodiment and the first embodiment is that a limit column 25 for limiting the fixed plate 23 is provided on the fixed plate 23 and the bottom plate 21.

[0044] In this embodiment, the limiting column 25 limits the downward movement distance of the fixing plate 23, thereby preventing the elastic support from being damaged by excessive pressure. Example 3

[0045] like Figure 2-3 As shown, this embodiment is obtained by adding technical features such as an inclined surface on the basis of the second embodiment. The remaining technical features are the same as those of the second embodiment, and the similarities are not repeated here. The difference between this embodiment and the second embodiment is that: the inner bottom angle of the axial guide ring 62 is an inclined surface, the position on the outer sliding block 53 and the punch insert 54 that contacts the inclined surface on the guide ring is also an inclined surface, the side of the punch insert 54 that contacts the inner insert block 32 is also an inclined surface, and the top of the inner insert block 32 is also an inclined surface.

During the downward movement of the axial guide ring 62, the inner side wall of the axial guide ring 62 pushes the outer slide block 53 and the punch insert 54 into the gap between the punch insert 54 and the pressing block 51, and is sleeved on the mold core 31. Part 54 moves toward the die insert 4 and compresses the pressure spring 55. When the axial guide ring 62 fits with the fixed block, the fixed block is pressed down further, the elastic support column 22 is deformed, forcing the insert block 32 to be inserted into the core 31, and pushing the die insert 4 to move toward the punch insert 54, thereby performing the rib punching operation. When the fixed block contacts the limiting column 25, the rib punching operation is completed, the downward pressure of the upper mold assembly is removed, and under the action of the elastic support column 22, the pressure spring 55 and the cover plate reset spring 64, the fixed block, the axial guide ring 62 and the punch insert 54 are reset.
