Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile stamping die, in particular to a die limiting assembly and a die using the limiting assembly. BACKGROUND

[0002] The automobile body-in-white is mainly produced by stamping, and the upper die seat and the lower die seat need to be in a non-closed state when the die is stored, so as to prevent the internal working mechanism from being damaged, such as preventing the service life of the internal elastic element from being shortened due to long-term pressure, preventing the die edge from being damaged, etc. Therefore, the die needs to be stored by a storage device when not in use.

[0003] The existing storage limiting assembly mainly includes a working limiting block, a storage limiting block, and a chain therebetween. The upper surface of the working limiting block is processed with a groove, and the bottom of the storage limiting block is provided with a circular table. When the die is not working, the storage limiting blocks are stacked on the working limiting block, and the circular table of the storage limiting block is clamped in the groove of the working limiting block. The working limiting block is fixedly installed on the lower die seat by screws, and the storage limiting block is removed and placed on the table surface of the lower die seat when the die is working. When the die is stored, the storage limiting blocks are stacked on the working limiting block, and then the die is closed. The storage limiting blocks support the upper die seat to a certain height, avoiding complete pressing of the die. In order to prevent the loss of the storage limiting block, the working limiting block and the storage limiting block are connected by the chain when the die is in use. This working method is simple and convenient, but the chain is often broken during use, and the storage limiting block is easy to fall into the die. If it is forgotten to take out, the die will be damaged or the storage limiting block will be crushed and fly out, causing a safety accident.

[0004] In view of the above problems, a stamping die storage limiting device and a stamping die are disclosed in Chinese patent application with application publication No. CN106825248A. The stamping die storage limiting device is a die limiting assembly, which includes a storage limiting block, an installation block with a U-shaped groove installed on the lower die seat, and a connecting rod rotatably installed in the U-shaped groove of the installation block. This stamping die storage limiting device places the storage limiting block between the lower die seat and the upper die seat when the die is not working by rotating the connecting rod, so as to ensure that there is a certain gap between the upper die seat and the lower die seat. At the same time, the movement track of the storage limiting block is located on the outside of the die, which also effectively prevents the storage limiting block from falling into the die. However, the structure of this die limiting device is complex, and it is necessary to set an installation plate on the lower die seat and open a groove and a hole thereon, which has a complex processing process and high material cost, and high maintenance and replacement cost in the later period. SUMMARY

[0033] The specific embodiments of the present application will be further described below in conjunction with the accompanying drawings, but are not limited thereto.

[0034] The specific embodiments of the present application will be further described below in conjunction with the accompanying drawings, but are not limited thereto. Figures 1 to 5 As shown in the figure: the mold limiting assembly includes a working limiting block 1, a hanging seat 2, a storage limiting block 3, and a spring pin 4. A groove 7 is formed on the working limiting block 1. The storage limiting block 3 is provided with a protrusion 6 that cooperates with the groove 7 on the working limiting block 1 to position and cooperate the storage limiting block 3 with the working limiting block 1. One side surface of the storage limiting block 3 is also provided with a hook 5. The hook 5 includes a connecting portion perpendicular to the side wall of the lower mold seat 8 and a hanging portion connected perpendicularly to the connecting portion. The hanging seat 2 is provided with a U-shaped groove for the hanging portion of the hook 5 to hang. The groove side wall of the U-shaped groove is connected with two side extending portions. Screw mounting holes 10 are provided on both side extending portions. The hanging seat 2 is fixed on the side wall of the lower mold seat 8 of the mold through the screws. The thickness of the hook 5 is consistent with the groove depth of the U-shaped groove, so that the hanging portion of the hook 5 can be stably hung in the U-shaped groove of the hanging seat 2 and tightly abut against the side wall of the lower mold seat 8, reliably positioning the hook 5 and preventing it from falling off. The spring pin 4 is elastic and is arranged above the U-shaped groove and can be retracted by manually pressing and automatically returned to the original position when manually released. After manually pressing the spring pin 4, the storage limiting block 3 can be hung on the hanging seat 2. After being placed, the elastic pin 4 will automatically pop out to stop the storage limiting block 3, preventing it from falling off. When the upper and lower mold seats are used upside down due to special work of the mold, the spring pin 4 can effectively stop the storage limiting block 3.

[0035] The use method of the mold limiting assembly is as follows: Figures 6 to 9As shown, when the mold is not working, the ejector pin 4 is pressed to take out the storage limiting block 3 from the hanging seat 2, the protrusion 6 on the storage limiting block 3 is aligned with the groove 7 of the working limiting block 1, so that the storage limiting block 3 is stacked above the working limiting block 1 to support the upper mold seat 9 of the mold and prevent the upper mold seat 9 and the lower mold seat 8 of the mold from closing; when the mold is working, the storage limiting block 3 is taken out from the working limiting block 1, the ejector pin 4 is pressed, the storage limiting block 3 is hung on the hanging seat 2, and then the ejector pin 4 is automatically ejected to block the storage limiting block 3 to prevent it from falling off. The storage limiting assembly of this structure does not use a chain, which well avoids the original chain breaking phenomenon, is simple to operate, has a good positioning and fixing effect on the storage limiting block 3, and is very safe to use.

[0036] In the above embodiment, the hanging seat is fixed on the side wall of the lower mold seat by screws, and in other embodiments, the hanging seat can also be fixed by other ways, for example, the hanging seat can be welded on the side wall of the lower mold seat to realize the fixation of the hanging seat.
