[0003] At present, after the stamping die has processed the material, the material is tightly attached to the inner wall of the die, making it difficult to quickly remove it. The demoulding mechanism of the existing stamping die usually requires manual operation, making it difficult to automatically eject the material from the die, reducing the demoulding efficiency of the die, increasing the operating steps of the staff, and reducing the convenience of the stamping die. Utility Model Content

Two grooves matching the push plates are symmetrically opened on the bottom side of the inner wall of the lower mold, and a spring is connected between the top side of the inner wall of the cavity and the concave plate. Connecting plates are connected to both sides of the concave plate, and through grooves are opened between the two sides of the lower mold and the cavity. The connecting plate passes through one side of the outer wall of the lower mold through the through groove, and fixed plates are connected to both sides of the upper mold, and a pull rope is connected between the connecting plate and the fixed plate; a pressing assembly is arranged between the bracket and the upper mold.

[0010] Preferably, the outer wall of the guide rod is provided with threads, and the guide rod is threadably connected to the rubber limit block through the threads.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The utility model sets up a top die assembly structure, controls the upper die to move upward through a telescopic cylinder, and the upper die pulls the pull rope through a fixed plate. After the pull rope is straightened, it drives the concave plate to move upward inside the cavity through a connecting plate, so that the spring is compressed and the push plate is driven to push the finished product upward, so that the finished product quickly separates from the lower die. Afterwards, when the upper die moves downward, the push plate moves to the inside of the groove under the elastic force of the spring, so that the product is automatically ejected from the die, thereby improving the demolding efficiency of the die. No staff operation is required, which improves the convenience of the stamping die.

[0013] (2) The utility model sets a downward pressing component structure. During the upward movement of the upper mold, one end of the guide rod will pass through the top of the upper mold and enter into the interior of the through hole. Then, the upper mold is controlled to move to the bottom of the rubber limit block for contact. During this process, the conical block extends out of the bottom of the upper mold and presses down the finished product on the outer wall of the upper mold to separate it from the upper mold, thereby realizing the removal of the finished product stuck on the surface of the upper mold and preventing the finished product from being stuck on the surface of the upper mold after stamping is completed, which is convenient for operators to use.
