Description

Technical Field

[0001] The utility model relates to the technical field of graphite crucible production, in particular to a graphite crucible molding die. Background Art

[0002] Graphite crucible is a special crucible made of graphite raw materials. It has good thermal conductivity and high temperature resistance. During high-temperature use, its thermal expansion coefficient is small, and it has certain resistance to strain from rapid heating and cooling. It also has excellent chemical stability. Therefore, it is widely used in metallurgy, casting, machinery, chemical industry and other industries. In the production process of graphite crucible, molding molds are required for production.

[0003] Patent No. CN202222552927.9 discloses a graphite crucible forming mold, which belongs to the field of graphite crucible production, including a base, a die is installed on the top of the base, and the die includes a lower die fixedly connected to the base and an upper die spliced ​​on the top of the lower die. Support columns are fixedly installed at the four corners of the top of the base, and a top plate is fixedly connected to the top of the support column. A hydraulic cylinder is fixedly installed in the middle of the top plate, and a convex die matched with the die is fixedly connected to the lower end of the hydraulic cylinder. A screw is rotatably installed on one side of the die at the top of the base, and a driving member for driving the screw to rotate is installed at the bottom of the base. A screw block is fixedly connected to one side of the upper die, and the screw block is threadedly sleeved on the screw.

[0004] Although the above patent provides a screw, a drive member and a screw block so that after the crucible is formed, the upper mold can be raised to leave the lower half of the crucible in the lower mold and expose the upper half, thereby facilitating the removal of the crucible, during the forming process of the graphite crucible, since the original integrated mold is converted into a split mold, there will be a gap at the connection of the split mold. This gap will inevitably cause the product to have ridges at this point, which requires subsequent grinding treatment, affecting its forming effect and resulting in poor use of the mold.

[0026] The bearing seat 12 is connected to the base 1 by screws, and the sponge pad 11 is bonded to the bearing seat 12. When the lower mold seat 10 is tilted to a certain angle, the graphite crucible can automatically separate from the lower mold seat 10 and fall into the sponge pad 11 on the bearing seat 12 by relying on its own gravity, and the sponge pad 11 provides buffering protection for it.

[0027] The mold cavity 3 is formed on the lower mold base 10, the guide hole 9 is formed on the lower mold base 10, a support 4 is welded on the back wall of the base 1, the support 4 is an L-shaped structure, the graphite crucible is formed in the mold cavity 3, and the guide hole 9 guides the upper mold base 5 during the mold closing process.

[0028] An electric push rod 6 is fixed to the support 4 by bolts, and an upper die base 5 is arranged on the output end of the electric push rod 6. The electric push rod 6 drives the upper die base 5 to move and close the die with the lower die base 10.

[0029] Guide columns 8 are formed at the four corners of the bottom end of the upper mold base 5, and a mold core 7 is formed in the middle of the bottom end of the upper mold base 5.

At this time, the raw material is injected into the mold cavity 3, and then the electric push rod 6 is controlled to work. The electric push rod 6 drives the upper mold base 5 to move and close the mold with the lower mold base 10. The guide column 8 is combined with the guide hole 9 to ensure smooth and orderly closing of the mold. The mold core 7 is combined with the mold cavity 3 to produce a graphite crucible. After the graphite crucible is formed, the electric push rod 6 drives the upper mold base 5 to separate from the lower mold base 10, and then the motor 13 drives the lower mold base 10 to flip through the turntable 14 to tilt it at a certain angle. At this time, relying on the gravity of the graphite crucible itself, it can automatically separate from the lower mold base 10 and fall into the sponge pad 11 on the supporting seat 12.
