Die head structure of solid carbon dioxide forming machine

The utility model discloses a die head structure of a solid carbon dioxide forming machine. The die head structure comprises a die head body, a die head connecting rod, a die, a positioning hole and a positioning mechanism, the positioning mechanism is arranged, the pressing rod drives the moving plate to move towards the right end through the connecting plate, the swing arm drives the positioning rod to move towards the upper end through the bearing rod, and therefore the positioning rod at the upper end of the first clamping rod mechanism and the positioning rod at the upper end of the second clamping rod mechanism release the insertion state of positioning holes, and a mold can be taken down from the inner side of the mold head body. The traditional mode of fixing by adopting bolts is changed, and the disassembly quickness is increased; when a die is embedded into the inner side of the die head body, a positioning rod is pushed to move towards the upper end, the positioning rod pushes a moving plate to mov
