Abstract

The invention discloses an extrusion die which comprises a shaft handle, an upper shaft plate cushion, an upper shaft plate sleeve, a punch sleeve, connecting column head sleeves, vertical pulling rods, a die connecting middle end, an ejecting rod and a lower horizontal support. The shaft handle is arranged at the upper end of the upper shaft plate cushion and penetrates through the center of an upper shaft plate. A lower shaft connecting body is connected with part of the shaft handle through the center of the punch sleeve. The connecting column head sleeves are arranged at the lower ends of upper end connecting columns. The vertical pulling rods vertically penetrate through a lower die plate and the lower horizontal support so as to connect the lower die plate and the lower horizontal support. The die connecting middle end is connected with the lower end face of a lower die core. The ejecting rod is arranged at the lowermost position of the die connecting middle end. The bottom end of the ejecting rod is connected with the lower horizontal support. The lower horizontal support is connected to the left side and the right side of the vertical pulling rods in a penetrating mode. The extrusion die is innovated and improved on the basis of a traditional die structure, and therefore a more complete finished product can be obtained through the whole die in the machining process.
