[0002] Currently, in the stamping die processing and production process, due to the specific nature of the stamping process, that is, each stamping die corresponds to a specific product shape, and multiple stamping dies are required to complete the production of multiple products with different shapes, this often leads to low work efficiency. At the same time, when the stamping is completed, it is often difficult to remove the processed product from the die cavity because the product is tightly attached to the die cavity. Therefore, we have introduced a variable die cavity mechanism. Utility Model Content

When different mold cavities need to be changed, the pull frame is pulled, which moves the rectangular rod. The rectangular rod drives the rotating shaft to rotate through the guide block and strip frame. The guide block slides within the strip frame. When the rotating shaft rotates, it drives multiple wire ropes to pull the corresponding push plate. The push plate squeezes the spring and simultaneously drives the locking rod. After one end of the locking rod slides out of the locking groove, the mold base can be removed from the positioning block. After replacing the mold base, it is placed on the positioning block. The pull frame is then released, and the spring pushes the push plate, causing the locking rod to engage with the corresponding locking groove. This facilitates mold cavity replacement, increases replacement efficiency, and reduces the labor intensity of workers. Attached Figure Description
