Abstract：

The structure of gas stove cover was analyzed, according to the stamping sequence, three sets of composite dies including blanking+drawing ①, trimming+punching, drawing ②+pressing were designed, and the automatic demolding mechanism in the die was designed. Then, for the blanking+drawing ① composite die, in order to prevent the upper die from getting stuck during the descent process and the material from wrinkling during drawing, a rubber ring was installed in the lower die. Meanwhile, for the trimming+punching composite die, in order to facilitate demolding, a discharge plate was set in each of the upper and lower dies, and the internal guide column and guide sleeve were set for the discharge plate of the lower die to ensure that the discharge plate of the lower die moved smoothly up and down. Furthermore, for the drawing ②+pressing composite die, the spring was set in the lower die to lift the pressing die and together with the product, which was beneficial for removing the product. Finally, in order to ensure smooth up and down movement of the pressing die, the internal guide column and guide sleeve were installed in the pressing die.
