[0028] As Figure 2 and 3 shown, the lower die body 1 is manufactured by casting. Concave platforms are provided at both ends of the middle part of the lower die body 1, and concave pits are provided on the upper surface of the lower die body 1. Four positioning column holes are machined in the concave pits. Four screw holes are provided on the lower die insert 2, and the lower die insert 2 can be fixed in the concave pit of the lower die body 1 through screws. There are two positioning columns 3 in total. Circular holes are provided at the top for easy taking. The middle and upper parts are cylinders, and the cylinder diameter is slightly smaller than the diameter of the positioning process hole on the blank. The blank positioning process hole passes through the middle and upper parts of the positioning column to achieve the positioning of the blank. The middle and lower parts are a structure of a cylinder plus a cuboid, and the middle and lower parts are inserted into the positioning column holes to achieve the positioning function. There are two positioning hole plugs 4 in total, and the diameter has a clearance fit with the positioning column holes on the lower die body 1, and is used to fill the unused positioning column holes.
