The invention achieves the above purpose by the following technical means:
a graphite crucible one-step forming die comprises a die main body, a movable front door and a door opening and closing oil cylinder, wherein the movable front door is covered at the right end of the die main body in a sealing manner, and a piston rod of the door opening and closing oil cylinder is connected with the movable front door; the mould main part includes outer body and inner core, and the outer body is the hollow structure of both ends open-ended, places the outer body in the inner core, forms a runner between outer body, inner core and the activity qianmen.
Preferably, the outer tube body comprises a large-diameter section, an inclined section and a small-diameter section, and the inclined section is arranged between the large-diameter section and the small-diameter section.
Preferably, the movable front door comprises a left movable front door and a right movable front door, the door opening and closing oil cylinder comprises a left door opening and closing oil cylinder and a right door opening and closing oil cylinder, a piston rod of the left door opening and closing oil cylinder is connected with the left movable front door, and a piston rod of the right door opening and closing oil cylinder is connected with the right movable front door.
Preferably, the movable front door further comprises a plug pin which is used for controlling the opening or locking of the movable front door through plugging and unplugging actions.
Compared with the prior art, the invention has the characteristics that:
1. the crucible body manufactured has high density, high strength and uniform texture;
2. the rejection rate is low, and the production cost is low;
3. the operation is simple, and the labor is saved;
4. the crucible body can be freely controlled according to the requirement;
5. the crucible body and the crucible bottom are integrally formed at one time, and the density of the whole crucible body is uniform.
