Description

Technical Field

[0001] This utility model relates to the field of garage door motor technology, and in particular to a mold for producing steel ladle bottom bricks. Background Technology

[0002] Ladle bottom bricks are refractory materials used in the working layer at the bottom of the ladle. They are mainly used to withstand the impact of molten steel, provide heat insulation, and fix the position of the nozzle. Ladle bottom bricks are generally made of alumina-magnesia-carbon bricks, which have high slag resistance, high temperature strength, and thermal shock resistance. They can withstand the impact of molten steel and slag erosion. The production method of ladle bottom bricks is to pour the mixed magnesia-carbon brick slurry into a mold and press it into shape using a press. However, traditional molds are mostly single-opening, and after the bricks are formed, the mold needs to be removed manually to separate the bricks from the mold. The demolding efficiency is low, and the inner wall of the mold is prone to residue after production and processing. The residue can easily affect the production quality of the next batch of ladle bottom bricks. In order to improve this situation, a mold for the production of ladle bottom bricks is proposed.

[0003] For example, the production mold for magnesia-carbon bricks disclosed in the authorization announcement number CN219820065U includes a base, and the base is provided with a demolding and picking mechanism. The demolding and picking mechanism includes a mounting seat fixedly connected to the top of the base, two motors fixedly connected to the top of the base, and a threaded rod rotatably connected to the output end of the motor. A movable bottom mold slidably connected to the mounting seat is threaded to the outer side of the threaded rod. Electric push rods located on the left and right sides of the mounting seat are fixedly connected to the top of the base. Although it enables the two side mold frames to cooperate with the movable bottom mold to form a mold cavity to accommodate the magnesia-carbon brick material, so that the hydraulic device can press the magnesia-carbon brick material. After pressing and molding, the two side mold frames can be flipped by the electric push rod to achieve quick demolding and reduce damage. The motor can drive the movable bottom mold to move the magnesia-carbon brick away from under the hydraulic device, making it easy to pick up the molded magnesia-carbon brick, thereby improving the safety of use. However, the existing production molds have not solved the problems that make it difficult to lift the bottom brick of the ladle and separate it from the bottom mold during use, and that it is not easy to clean the raw material residue adhering to the inner wall of the mold by rolling. This affects the efficiency of the ladle bottom brick demolding and the production quality. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for producing bottom bricks of steel ladles, so as to solve the problems mentioned in the background art, which are that the production mold is not convenient for lifting the bottom bricks of steel ladles and separating them from the bottom mold, and is not conducive to cleaning the raw material residues adhering to the inner wall of the mold, thus affecting the efficiency and production quality of the bottom bricks of steel ladles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for producing bottom bricks of steel ladles, comprising a mold base and a placement base. Placement bases are provided on both sides of the mold base. Multiple sets of placement racks are arranged at equal intervals inside the mold base. Two sets of second hydraulic cylinders are provided on the outer wall of the mold base. Each output end of the second hydraulic cylinder is equipped with a rack, which is slidably connected to the mold base. A second lead screw is movably mounted on the top of each placement rack. Gears are provided on the surface of each second lead screw. A lifting sleeve is provided on the outer surface of the second lead screw above the gears. A second threaded sleeve is fixedly mounted on the inner wall of each lifting sleeve and is threadedly connected to the second lead screw. A sliding frame is provided on the outer wall of each lifting sleeve and is slidably connected to the placement rack. A fixed plate is symmetrically arranged on the top of the mold base. A movable plate is slidably arranged on the top of the mold base on one side of the fixed plate.

[0006] Preferably, each of the placement seats has a support frame symmetrically arranged on its outer wall, and each of the placement seats has an integrated frame above it, with the integrated frame connected to the support frame.

[0007] Preferably, a first lead screw is movably installed inside the integrated frame, and a first servo motor is provided on the side wall of the integrated frame, with the output end of the first servo motor connected to the first lead screw.

[0008] Preferably, the surface of the first lead screw is fitted with a first threaded sleeve, and the first threaded sleeve is threadedly connected to the first lead screw.

[0009] Preferably, each of the first threaded sleeves is provided with an L-shaped bracket on its side wall, and each of the L-shaped brackets is provided with a second servo motor at its top.

[0010] Preferably, the output end of the second servo motor is equipped with a drive shaft, and the surface of the drive shaft is provided with a cleaning roller.

[0011] Preferably, each of the placement seats is provided with a first hydraulic cylinder on its inner wall, and each of the first hydraulic cylinders is equipped with a push arm at its output end, and the push arm is connected to the moving plate.

[0012] Preferably, each of the placement seats has a track symmetrically arranged at its top end, and each of the movable plates has a slider symmetrically arranged on its outer wall, with the slider slidingly connected to the track.

[0014] (1) The raw material of the bottom brick of the ladle is placed on the mold base. The fixed plate and the moving plate surround the raw material. With the cooperation of the mold base, the press drives the upper mold to compact and form the raw material. After compaction and forming, the first hydraulic cylinder drives the push arm to move. The push arm drives the moving plate away from the fixed plate, so that the moving plate is separated from the formed bottom brick of the ladle. The second hydraulic cylinder drives the rack to move. The rack drives the gear to rotate. The gear drives the second screw to rotate. The second screw drives the second threaded sleeve to move upward. The second threaded sleeve drives the lifting sleeve to move upward. Multiple sets of lifting sleeves lift the formed bottom brick of the ladle and separate it from the mold base, so that the formed bottom brick of the ladle can be taken out. This completes the production of the bottom brick of the ladle. It realizes the linkage lifting of the bottom brick of the ladle and the separation of it from the bottom mold, which facilitates the output and picking of the formed bottom brick of the ladle and improves the efficiency of the bottom brick of the ladle demolding.

[0015] (2) During the demolding process, the moving plate moves away from the fixed plate. At this time, the inner wall of the moving plate is close to the cleaning roller. The first servo motor drives the first lead screw to rotate, the first lead screw drives the first threaded sleeve to move, and the first threaded sleeve drives the drive shaft and cleaning roller to move through the L-shaped frame. While the cleaning roller is moving, the second servo motor drives the cleaning roller to rotate through the drive shaft. The cleaning roller cleans the raw material residue adhering to the inner wall of the moving plate to ensure the cleanliness of the inner wall of the mold and avoid the raw material residue from affecting the production of the next batch of steel ladle bottom bricks, thereby improving the production quality of steel ladle bottom bricks.
