Description

Technical Field

[0001] This utility model relates to the technical field of mold clamping devices, and in particular to a clamping device for automotive stamping dies. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded. It is often referred to as the "mother of industry."

[0003] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0004] Some automotive parts are manufactured using stamping dies. With use, these dies wear down and require regular inspection. Furthermore, when the manufactured automotive parts change, the dies also need to be replaced. However, dies are typically secured with bolts, making replacement inconvenient. Therefore, we propose a clamping device for automotive stamping dies to address these issues. Utility Model Content

[0050] Operating principle:

[0051] The mold body 1 is placed on the platform 2. The clamping unit 6 clamps the mold body 1 by moving the rod 4 and clamping the positioning strip 10 with the limiting strip 9. At the same time, the adjusting unit 7 moves the B connecting block 12 into the A connecting groove on the A connecting block 11 through the moving plate 5 and the quick release unit 8, connecting the moving rod 4 and the mold body 1 together and limiting the mold body 1. When disassembling, the quick release unit 8 moves the B connecting block 12 away from the A connecting groove on the A connecting block 11. Then, the clamping unit 6 and the adjusting unit 7 move the moving rod 4 and the positioning strip 10 away from the limiting strip 9, so that the mold body 1 can be disassembled and replaced from the platform 2.
