The die structure was relatively basic. Today, aluminum alloy stamping dies are widely used in the production of various complex and precision parts, from automobile body panels to key structural components in the aerospace field. However, existing aluminum alloy stamping dies still reveal many shortcomings in use. The process of changing punches is complicated, and the complicated process of changing punches leads to long downtime of equipment, which significantly reduces the output per unit time. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an aluminum alloy stamping die, which aims to improve the problem in the prior art where the complicated process of changing the punch leads to long-term equipment downtime and a significant reduction in output per unit time.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum alloy stamping die, comprising a lower die base and a lower die, wherein fixed blocks are fixedly connected to the four corners of the top of the lower die base, and multiple clamping grooves are formed on the outer wall of the fixed blocks; a rotating column is rotatably connected to the inner wall of the lower die, and a driving bevel gear is fixedly connected to the outer wall of the rotating column; a driven bevel gear is meshed with the outer wall of the driving bevel gear; a rotating sleeve is fixedly connected to the outer wall of the driven bevel gear; a threaded rod is threadedly connected to the inner wall of the rotating sleeve; a clamping block is fixedly connected to the other end of the threaded rod; a guide rail is fixedly connected to the top of the fixed blocks; and an adjustable unloading mechanism is provided on the outer wall of the guide rail for automatic unloading.

[0006] As a further description of the above technical solution:

[0007] The adjustable unloading mechanism includes an upper mold base, the inner wall of which is slidably connected to the outer wall of the guide rail. A plurality of sliding columns are slidably connected to the middle of the upper mold base. An unloading plate is fixedly connected to the bottom of the sliding column. A spring is provided on the outer wall of the sliding column. A limit block is fixedly connected to the top of the sliding column. A synchronization plate is slidably connected to the upper end of the sliding column. A bolt is threadedly connected to the middle of the synchronization plate.

[0009] A knob is fixedly connected to one end of the rotating column, and a concave mold is provided on the top surface of the lower mold.

[0010] As a further description of the above technical solution:

[0011] A top plate is fixedly connected to the top of the guide rail, and the outer wall of the guide rail is slidably connected to the upper mold base through a sliding sleeve.

[0012] As a further description of the above technical solution:

[0013] A pad is fixedly connected to the bottom of the upper mold base, and an upper mold is fixedly connected to the bottom of the pad.

[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a knob drives a rotating column to rotate. A driving bevel gear is fixedly connected to the outer wall of the rotating column. The driving bevel gear meshes with a driven bevel gear. A rotating sleeve is fixedly connected to the outer wall of the driven bevel gear. As the rotating sleeve rotates, a threaded rod is threadedly connected to the inner wall of the rotating sleeve. One end of the threaded rod is fixedly connected to a clamping block. The clamping block is square. A groove on the outer wall of the lower mold fits the outer wall of the clamping block, causing the clamping block to move outward. The top surface of the clamping block is inclined. When the top surface of the clamping block contacts the top surface of the clamping groove, the threaded rod pushes the two clamping blocks outward synchronously, causing the lower mold to move downward, thus fixing the lower mold.

[0022] 2. In this utility model, when the upper die base slides down to stamp, the stripper plate first contacts the aluminum alloy. Then, as the stamping continues, the second spring is compressed, and the sliding column slides upward. After the stamping is completed, the upper die base moves upward, and the stripper plate ejects the stamped part under the action of the second spring, thus achieving unloading. By rotating the second bolt, the synchronous plate moves upward, and the limiting block at the top of the sliding column is at the upper end of the synchronous plate, that is, multiple sliding columns move upward synchronously, and the stripper plate also moves upward synchronously. This allows for rapid adjustment according to aluminum alloy plates of different thicknesses, improving the mold's adaptability to plates of different specifications. Attached Figure Description
