[0036] The usage process of this utility model is as follows: Place the product raw material on the top of the concave mold 13, and drive the upper mold to move through the telescopic device of the machine tool. When the upper mold moves, it drives the first punch 5 to move downward through the fixed block 4, so that the first punch 5 presses down and stretches the product raw material on the top of the concave mold 13, so that the product raw material is formed in the forming hole 14.
[0037] After product 6 is formed, the telescopic device and the upper ejector mechanism are activated. The telescopic device drives the fixed block 4 through the upper mold to move the first punch 5 upward. When the first punch 5 moves upward, the upper ejector mechanism pushes the ejector rod 15 upward, thereby assisting the product to be removed from the die 13. When product 6 contacts the bottom of the first ejector sleeve 8, the product is pressed against the bottom of the first ejector sleeve 8. The first ejector sleeve 8 will eject the product that is pressed against and wrapped on the first punch 5. The product is pushed upward by the force of the punch press and is ejected. The ejection force is stable and reliable, completely avoiding the problem of product sticking to the die, realizing fully automatic continuous production, significantly improving production capacity, and meeting the needs of customers for large quantities.
