Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and more specifically, relates to a device for adjusting the external dimensions of a stamping die. Background Technology

[0002] With social development and improved living standards, the application of stamping dies has become more and more widespread. However, the existing stamping die angles sometimes result in poor angles in the products produced by metal stamping dies. This prevents the dimensions from being adjusted to the desired values, affecting the size and leading to defective or even scrapped products. Furthermore, die maintenance is very inconvenient, resulting in low production efficiency for stamping dies.

[0003] Meanwhile, traditional stamping dies require disassembling die components and adjusting clearances or shapes by replacing shims or remachining positioning parts when adjusting dimensions, which has the following drawbacks:

[0004] 1. The mold adjustment process is time-consuming, which affects production efficiency;

[0005] 2. Repeated disassembly and reassembly can lead to a decrease in mold precision and increase maintenance costs;

[0006] 3. Manual operation is complex and highly dependent on the experience of technical personnel. Utility Model Content

[0007] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a device for adjusting the external dimensions of a stamping die, including a lower die base 10, a lower pad 20, and a lower template 30. One side of the lower pad 20 is connected to the lower die base 10, and the other side is connected to the lower template 30. The lower template 30 is provided with an upper die entry block 40 and a lower die entry block 50. The upper die entry block 40 is connected to the lower template 30 by a first bolt 60. The lower die entry block 50 is located below the upper die entry block 40. The lower die entry block 50 can move vertically relative to the lower template 30. The lower pad 20 is provided with an external die adjustment mechanism 70 for adjusting the gap between the lower die entry block 50 and the upper die entry block 40. The external die adjustment mechanism 70 is connected to the lower die entry block 50. The external adjustment mechanism 70 includes an adjusting rod 701, a slider 702, and a slide rail 703. The slide rail 703 is connected to the lower pad 20, and the slider 702 is slidably connected to the slide rail 703. The top end of the adjusting rod 701 is connected to the slider 702, and the slider 702 is connected to the lower die entry block 50. By adjusting the adjusting rod 701, the lower die entry block 50 is moved upward, thereby reducing the gap between the lower die entry block 50 and the upper die entry block 40. With the external adjustment mechanism 70, dimensional correction can be completed without disassembling the mold components, reducing downtime and greatly improving production efficiency. At the same time, it is not only simple and quick to operate, but also reduces maintenance costs, meets the requirements of high-precision stamping, is compatible with various mold structures, and has strong versatility.

One side of the lower backing plate 20 is connected to the lower die base 10, and the other side is connected to the lower template 30. The lower template 30 is provided with an upper die insert block 40 and a lower die insert block 50. The upper die insert block 40 is connected to the lower template 30 by a first bolt 60. The lower die insert block 50 is located below the upper die insert block 40. The lower die insert block 50 can move vertically relative to the lower template 30. The lower backing plate 20 is provided with a mechanism for adjusting the distance between the lower die insert block 50 and the upper die insert block 40. An external mold adjustment mechanism 70 for gap reduction is provided. The external mold adjustment mechanism 70 is connected to the lower mold entry block 50. The external mold adjustment mechanism 70 includes an adjustment rod 701, a slider 702, and a slide rail 703. The slide rail 703 is connected to the lower pad plate 20.
