[0021] Beneficial effects:

[0022] The utility model provides a hardware stainless steel stamping die. When it is necessary to process and produce stainless steel products of different styles, the upper template and the lower template need to be replaced. The staff uses a plurality of screws to limit and fix the upper template and the lower template. This installation operation process has high repetition and is time-consuming and labor-intensive. The template replacement efficiency is low, which affects the progress of the processing and production operations. At this time, the upper template is first disassembled, and the adjusting rods on both sides of the installation box are rotated at the same time. During this process, the rotation directions of the two adjusting rods are opposite. The adjusting rod drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the round rod to rotate. The movable plate moves downward along the installation box with the help of the thread, and the movable plate drives the upper template to move downward out of the installation box through the support plate until the support plate moves out of the range of the installation box, and the support plates on the two movable plates are pulled out of the installation box.
