The first fixing block and the bottom mold installed inside the first fixing groove are removed. The first fixing block outside the bottom mold of the replacement magnesia-carbon brick production molding mold is installed inside the first fixing groove and fixed with fixing bolts. Then, the fixing bolts fixing the second fixing block and the mounting plate are removed. The second fixing block and the top mold are removed from the second fixing groove. The second fixing block of the top mold of the magnesia-carbon brick production molding mold to be replaced is installed inside the second fixing groove.

[0004] The aforementioned document proposes adding a structure for disassembling and assembling magnesia-carbon brick production molds to facilitate the production of magnesia-carbon bricks of different specifications. However, the problems of cumbersome material feeding and unloading and low continuous production efficiency still exist. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example

[0026] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 4, a molding device for processing magnesia-carbon bricks includes a mounting base 10, a guide rail 11 fixedly mounted on the top of the mounting base 10, a lifting platform 12 mounted above the guide rail 11, a mounting frame 13 slidably mounted in the middle of the guide rail 11, a molding frame 14 embedded inside the mounting frame 13, a closing component 15 movably mounted inside one side of the guide rail 11, multiple hydraulic cylinders 16 suspended at the bottom of the lifting platform 12, a lifting plate 17 fixedly mounted at the bottom of the hydraulic cylinders 16, a molding pressure plate 18 screwed at the bottom of the lifting plate 17, a vacuum pump 19 fixedly mounted on the top of the lifting plate 17, and discharge components 20 on both sides of the middle of the guide rail 11; a threaded rod 111 rotatably mounted in the middle of the guide rail 11, a drive motor 112 fixedly mounted at one end of the guide rail 11, and the actuator end of the drive motor 112 connected to the central shaft of the threaded rod 111; The bottom of the mounting frame 13 is slidably embedded inside the guide rail 11. A double-ended threaded tube 131 with a nut connected to the outer wall of the threaded rod 111 is installed through the bottom of the mounting frame 13. The top of the mounting frame 13 has two molded grooves 132 with one side open. Several positioning grooves 133 are opened at both ends and one side inside the molded grooves 132. Two through circular grooves 134 are opened on the closed side of the molded grooves 132. Several positioning strips 141 that fit into the positioning grooves 133 are welded to both ends and one side of the outer wall of the molded frame 14. Two mounting circular grooves 142 with a diameter larger than the through circular grooves 134 are opened on one side of the molded frame 14. A rotating cover 143 is rotatably installed inside the mounting circular grooves 142. Several miniature springs 144 are fixedly connected to one side of the rotating shaft of the rotating cover 143. The other end of the miniature springs 144 is fixedly installed on the inner wall of the mounting circular grooves 142.

[0027] As described above, the drive motor 112 can operate in both forward and reverse directions, driving the threaded rod 111 to rotate. The threaded nut connection drives the double-ended threaded tube 131 to push the mounting frame 13 to slide inside the guide rail 11. The double-ended threaded tube 131 has threads only at both ends, with a smooth hollow rod in the middle to prevent jamming due to excessively long threaded connection sections. The lifting plate 17's lifting coverage area is only one-third of the area above the middle of the guide rail 11. The sliding distance inside the guide rail 11 is 1.5 times the length of the mounting frame 13. This design ensures that each time the mounting frame 13 slides to the end of the guide rail 11, one molding groove 132 is always located directly below the lifting plate 17, while the other molding groove 132 is empty. The empty state is used to fill the magnesium-carbon brick mixture. The molding groove 132 directly below the lifting plate 17 is used for hydraulic molding of magnesia-carbon bricks. The two molding grooves 132 are used alternately, so that material can be replenished at the same time during the hydraulic molding process. There is no need to stop the operation after one hydraulic molding and spend extra time replenishing material, which greatly speeds up the batch molding rate. The molding frame 14 is fixed by several positioning strips 141 welded to the outer wall and inserted into the positioning grooves 133 on the inner wall of the molding groove 132. The outer wall structure of the molding frame 14 for molding different specifications of magnesia-carbon bricks is the same, but the internal capacity and shape are different. Depending on the selected molding frame 14, different sizes of molding pressure plates 18 are also selected and installed on the lifting plate 17 with bolts, and aligned with the top opening of the molding frame 14.

[0028] Please refer to the attached document carefully. Figure 1 , 3 As shown in Figures 4, 5, and 6, the enclosing component 15 includes two sliding grooves 151 formed inside one side of the mounting frame 13. A sliding sealing plate 152 is slidably mounted on the inner wall of each sliding groove 151. Limiting strips 153 are welded to both ends of the sliding sealing plate 152. Limiting grooves 154 for sliding of the limiting strips 153 are formed at both ends of the opening side of the molding groove 132. Two miniature telescopic rods 155 are fixedly installed at both ends of the bottom of the sliding groove 151, and limiting strips are fixedly connected to the top of the miniature telescopic rods 155. At the bottom of strip 153; two air guide pipes 191 are fixedly connected to both ends of the air pump 19; several fine air guide holes 192 are opened through the middle of the lifting plate 17 and the molding plate 18; the air guide pipes 191 are connected to the fine air guide holes 192; the discharge component 20 includes an inclined groove 201 fixed to one side of the middle of the guide rail 11; two electric push rods 202 are fixed to the other side of the middle of the guide rail 11; the center of the electric push rod 202 is aligned with the through groove 134 and the mounting groove 142.

[0029] As described above, the edge of the limiting strip 153 is right-angled, and the actuator of the miniature telescopic rod 155 passes through the limiting groove 154 and is supported on the limiting strip 153. During molding and feeding, the two miniature telescopic rods 155 are fully extended. At this time, the top of the sliding sealing plate 152 is flush with the top of the molding groove 132, and a part of the bottom is embedded in the sliding groove 151, sealing the opening side of the molding groove 132 to prevent material leakage. When it is necessary to discharge the molten magnesia-carbon brick, the two miniature telescopic rods 155 are fully retracted, the sliding sealing plate 152 is fully embedded in the sliding groove 151, and the opening side of the molding groove 132 is opened. At this time, the opening side of the molding groove 132 is aligned with the inclined groove 201. Then, the two electric actuators 202 extend simultaneously, and the actuator passes through the two through circular grooves 134 on the molding groove 132. Push open the rotating cover 143 to push the shaped magnesia-carbon brick into the inclined groove 201 for discharge. After discharge, the two electric push rods 202 are retracted, and the rotating cover 143 is reset under the pull of several micro springs 144. During the molding process, since the diameter of the rotating cover 143 is larger than the diameter of the through circular groove 134, the edge of the rotating cover 143 is blocked by the molding groove 132, preventing material leakage. When the hydraulic cylinder 16 extends and presses the molding plate 18 into the molding frame 14 for hydraulic molding, the air in the molding frame 14 will escape through several fine air guide holes 192. The air pump 19 draws air through the air guide pipe 191 to accelerate the rate of air escaping from the fine air guide holes 192, preventing the internal air pressure from accumulating during the hydraulic process, which could cause the cylinder to explode or a large amount of air to be squeezed into the mixture, resulting in loose and defective magnesia-carbon bricks.

[0030] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
