Description

Technical Field

[0001] The utility model relates to the technical field of graphite crucible production, in particular to a graphite crucible mold convenient for demolding. Background Technique

[0002] A graphite crucible mold is a mold used to manufacture crucibles. A crucible is a container used for melting and refining metals. Graphite crucibles are widely used in the metal smelting and casting industries due to their excellent high-temperature resistance, thermal conductivity, and chemical corrosion resistance.

[0003] When the existing graphite crucible mold forms a graphite crucible during production, it is necessary to demold the graphite crucible produced in the lower mold. However, the existing demolding tool generally uses a cylinder to push out the graphite crucible. However, the cylinder contacts the bottom of the formed graphite crucible, and the contact pressure is relatively large, easily damaging the bottom of the just-formed graphite crucible. Moreover, when the graphite crucible is formed, it can only be demolded, and the impurities generated on the inner wall of the mold after demolding cannot be cleaned, thus affecting subsequent work.

[0004] Therefore, it is necessary to design a graphite crucible mold convenient for demolding to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a graphite crucible mold convenient for demolding, which is used to solve the technical problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A graphite crucible mold convenient for demolding, including a base and a lower mold fixedly connected to the top of the base. An equipment chamber and a mold forming port are arranged inside the lower mold, and a square opening is communicated between the mold forming port and the equipment chamber. A first servo motor is fixedly connected to the top of the inner cavity of the base. The output shaft of the first servo motor is fixedly connected to a first threaded rod. The top of the first threaded rod is provided with a lifting mechanism inside the equipment chamber, and the top of the lifting mechanism is fixedly connected to a first equipment box. A second servo motor is fixedly connected to the top of the inner cavity of the first equipment box. The output shaft of the second servo motor is fixedly connected to a rotating shaft. The top of the rotating shaft is fixedly connected to a second equipment box. A first top block is fixedly connected to the top of the second equipment box. A third servo motor is fixedly connected to the top of the inner cavity of the second equipment box. The output shaft of the third servo motor is fixedly connected to a second threaded rod. A threaded sleeve square plate is threadedly sleeved on the outer surface of the second threaded rod. Two second top blocks are fixedly connected to both ends of the top of the threaded sleeve square plate. Two symmetric sliding blocks are slidably clamped on the top of the inner cavity of the first top block. Another second top block is fixedly connected to one side of the bottom of each of the two sliding blocks. A rotating block is rotatably connected between the two second top blocks on the same side, and a scraper is fixedly connected to the adjacent side of the two sliding blocks. The first top block is slidably arranged inside the square opening.

[0007] Preferably, the lifting mechanism includes a threaded sleeve disc which is threadedly sleeved on the outer surface of the first threaded rod. Two symmetrical chutes are formed in the inner wall of the equipment chamber. Two symmetrical second clamping blocks are fixedly connected to the outer surface of the threaded sleeve disc. The two second clamping blocks are respectively slidably arranged inside the two chutes. Two symmetrical connecting columns are fixedly connected to the top of the threaded sleeve disc. The tops of the two connecting columns are fixedly connected to the bottom of the first equipment box.

[0008] Preferably, the second threaded rod is rotatably arranged between the two sliding blocks. Openings are formed on both sides of the first top block. The two scraping plates are respectively slidably arranged inside the two openings.

[0011] The technical solution provided by the present utility model has the following beneficial effects compared with the prior art:

[0012] In the present utility model, through the lifting of the threaded sleeve disc, the first top block and the high-temperature resistant U-shaped sleeve are used to lift for the demolding work of the graphite crucible inside the mold. By contacting the wide surface of the top of the first top block with the bottom of the graphite crucible, the contact surface increases during pushing, and the pressure decreases, which is beneficial to reducing the bottom safety of the graphite crucible during demolding. By starting the third servo motor and the second servo motor, the sliding of the two sliding blocks can be utilized.
