The reinforcing plates 3 can be fixed on the top of the upper die 2 or the bottom of the lower die 10 by welding, so as to improve the integrity and stability between the reinforcing plates 3 and the upper die 2 or the lower die 10. The top surfaces of the two reinforcing plates 3 arranged at the top of the upper die 2 are respectively fixedly provided with a steel boss 4. The boss 4 can be fixed on the top of the upper die 2 by welding. Four bosses 4 correspondingly have four through grooves 12 formed in the four reinforcing plates 3, the upper die 2, the die body 1 and the lower die 10. A steel penetrating rod 7 is inserted into each of the four through grooves 12. The lower part of each penetrating rod 7 has a through hole 11 corresponding to the through hole 11 in the two reinforcing plates 3 arranged at the bottom of the lower die 10. A T-shaped bolt 8 is inserted into the through hole 11 in the corresponding position of the reinforcing plate 3 and the through hole 11 in the lower part of the penetrating rod 7. The T-shaped bolt 8 is locked with the reinforcing plate 3 and the lower part of the penetrating rod 7 by a fastening nut B9. The upper part of the penetrating rod 7 is externally screwed with a threaded line and locked with the boss 4 by a fastening nut A5. A compression gasket 6 is arranged between the fastening nut A5 and the boss 4, and the penetrating rod 7 penetrates the compression gasket 6.
