[0010] Beneficial effects

[0011] Compared with the prior art, the upper die opening and closing device of the cold and hot press forming machine has the following advantages:

[0012] 1. When the upper die of the mold needs to be opened upward, the first swing arm driving mechanism controls the swing of the first swing arm, the second swing arm driving mechanism controls the swing of the second swing arm, the hook body at one end of the second swing arm hooks the lifting lug of the upper die and pulls it upward, so that the upper die is turned over upward relative to the lower die, at this time, the mold is opened, and personnel can put the rough blank into the lower die. When the upper die needs to be closed, the first swing arm and the second swing arm are allowed to act cooperatively to put the upper die back on the lower die.
