[0003] The Chinese patent with announcement number CN207205218U discloses a high-efficiency and precise barrel centrifugal casting alloy furnace, which includes a shell, a flange, a motor, a transmission belt, a rotating table, a casting mold, a smelting furnace, a smelting furnace support frame, a vacuum pump carrier frame, a vacuum pump, a vacuum pipeline and a winch. The shell is a double-layer structure with a water flow trough between the layers. The flange is welded to the bottom of the shell, the motor is installed inside the shell through the flange, the motor and the rotating table are connected by a transmission belt, and the rotating table is divided into a rotating part and a fixed part. The advantages of the utility model are: it has the advantages of simple structure and easy use.

[0004] Regarding the above-mentioned related technologies, in the prior art, the operator uses a smelting furnace to melt a variety of metals, and then uses a winch and a smelting furnace support frame to pour the liquid metal into a casting mold to achieve metal casting. However, metal smelting will cause metal loss. If precise metal casting is to be achieved, the proportion of each metal component must be strictly controlled, otherwise it will be difficult to make the molded metal reach the specified performance. Therefore, before casting, it is necessary to sample and test the mixed molten metal to detect the content of the internal components of the molten metal. However, there is no technical means for sampling and testing the molten metal in the prior art. There is a possibility that the molded metal cannot reach the specified performance, which reduces the smelting effect of the smelting furnace. Summary of the invention

If the internal component detection data of the molten metal does not meet the standard, the corresponding metal is continued to be added to the holding furnace or continuous casting furnace through the feeding port until the internal component content of the molten metal in the temporary storage box meets the standard, thereby achieving the effect of metal casting. The operator uses the driving mechanism and the dipping rod to sample and test the molten metal in the holding furnace and the temporary storage box respectively. The molten metal detection in the holding furnace is used to semi-precisely compensate for the metal content difference, while the molten metal detection in the temporary storage box is used to fine-tune the metal content difference to ensure that the content of each component in the molten metal in the temporary storage box reaches the specified value.

[0009] By adopting the above technical scheme, when sampling the molten metal, the operator inserts the dipping rods into the limiting module one by one at the supplementary hole in advance. During this process, the spring sheet contacts the dipping rod and is deformed, and enters the installation ring groove until the limiting ring groove is aligned with the installation ring groove, and the spring sheet is reset and fits the inner wall of the limiting ring groove, thereby realizing the installation of the dipping rod. Subsequently, the rotating component is used to drive the limiting module to move so that the dipping rod is aligned with the clamping hole, and finally the clamping component is used to clamp the dipping rod, so that the dipping rod is lowered and disengaged from the rotating frame, until the dipping rod dips the molten metal in the insulation furnace, and then the moving component is used to put the dipping rod into the discharge box, and similarly, the molten metal in the temporary storage box is dipped, thereby realizing the effect of sampling the molten metal.

[0019] By adopting the above technical scheme, when taking materials, the operator places the dipping rod dipped in the molten metal in the insulation furnace in the first space, and places the dipping rod dipped in the molten metal in the temporary storage box into the second space through the material introduction port, and then uses the opening and closing component to simultaneously open the gates between the first space and the second space and between the second space and the third space, so that the two dipping rods fall into the third space together, and then opens the gates between the third space and the fourth space and between the fourth space and the material taking port in turn, so that the two dipping rods fall into the material taking port, and the dipping rods can be taken out, and finally the air in the fourth space is extracted by the vacuum assembly to ensure that the vacuum degree of the fourth space is consistent with the vacuum degree in the vacuum box, thereby achieving the effect of collecting the dipping rods.

[0020] Optionally, the opening and closing assembly includes an opening and closing cylinder, a metal rope, a steering wheel and a return spring. Two gates are provided, and the two gates are arranged opposite to each other. The opening and closing cylinder is installed on the discharge box, and the output shaft of the opening and closing cylinder is connected to one of the gates. A fixed frame is connected to the discharge box, and the steering wheel rotates on the fixed frame to connect the two gates. The metal rope is connected between the output shaft of the opening and closing cylinder and the other gate, and the metal rope is wound around the two steering wheels. The return spring is connected between the fixed frame and the other gate.

[0021] By adopting the above technical solution, when opening the gate, the operator starts the opening and closing cylinder to move one of the gates, and at the same time, through the cooperation of the metal rope and the steering wheel, the other gate moves synchronously, so that the distance between the two gates gradually increases, and the reset spring is compressed; when closing, the operator starts the opening and closing cylinder in the reverse direction, so that the metal rope is in a relaxed state, and the other gate moves in the reverse direction due to the force of the reset spring until the two gates touch, thereby achieving the opening and closing effect of the gate.

After the dipping stick is taken out, the vacuum pump is started to extract the air in the fourth space until the reading of the second vacuum gauge is consistent with the bottom number of the first vacuum gauge, so as to ensure that the vacuum degree in the fourth space is consistent with the vacuum degree in the vacuum box.

When sampling, the dipping rod touches the cover plate when it descends, causing the cover plate to rotate counterclockwise, and the connecting spring is compressed. After the dipping rod dips the molten metal and leaves the insulation shell, the cover plate rotates in the opposite direction due to the force of the connecting spring until it fits the baffle to reclose the sampling port.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Before casting, the operator discharges the molten metal from the smelting furnace into the holding furnace, and then from the holding furnace into the temporary storage box.

Then, the dipping rod is placed into the discharge box, and the molten metal in the temporary storage box is dipped in the same way. Finally, two dipping rods are taken out from the feeding port to detect the internal component content of the molten metal in the holding furnace and the temporary storage box. If the internal component detection data of the molten metal does not meet the standard, the corresponding metal is continued to be added to the holding furnace or continuous casting furnace through the feeding port until the internal component content of the molten metal in the temporary storage box meets the standard, thereby achieving the effect of metal casting. The operator uses the cooperation of the driving mechanism and the dipping rod to sample and test the molten metal in the holding furnace and the temporary storage box respectively. The molten metal test in the holding furnace is used to semi-precisely compensate for the metal content difference, while the molten metal test in the temporary storage box is used to fine-tune the metal content difference to ensure that the content of each component in the molten metal in the temporary storage box reaches the specified value. Compared with the existing technology, it can make the formed metal reach the specified performance as much as possible, improve the accuracy of molten metal smelting, and improve the smelting effect of the smelting furnace; 2. When clamping the dipping rod, the operator starts the lifting cylinder to lower the fixed shell until the top of the dipping rod is located between the two clamping rods, and then starts the rotating cylinder to rotate the rotating disk, driving the rotating rail to rotate. Through the restrictions of the rotating rail and the limiting groove, the two moving blocks move toward the center of the rotating disk at the same time, so that the clamping rod moves until the two clamping rods clamp the dipping rod, thereby achieving the effect of clamping the dipping rod; 3. When taking out materials, the operator places the dipping rod dipped in the molten metal in the insulation furnace in the first space, and places the dipping rod dipped in the molten metal in the temporary storage box into the second space through the feed port, and then uses the opening and closing component to simultaneously open the gates between the first space and the second space and between the second space and the third space, so that the two dipping rods fall into the third space together, and then opens the gates between the third space and the fourth space and between the fourth space and the feeding port in turn, so that the two dipping rods fall into the feeding port, and the dipping rods can be taken out, and finally the air in the fourth space is extracted by the exhaust component to ensure that the vacuum degree of the fourth space is consistent with the vacuum degree in the vacuum box, thereby achieving the effect of collecting the dipping rods; 4. When opening the gate, the operator starts the opening and closing cylinder to move one of the gates. At the same time, the other gate moves synchronously through the cooperation of the metal rope and the steering wheel, so that the distance between the two gates gradually increases and the reset spring is compressed; when closing, the operator starts the opening and closing cylinder in the reverse direction to relax the metal rope, and the other gate moves in the reverse direction under the action of the reset spring until the two gates touch, thus achieving the opening and closing effect of the gate.

The exhaust assembly 8 includes a first vacuum gauge 81, a second vacuum gauge 82 and an exhaust pump 83. The first vacuum pump, the second vacuum gauge 82 and the exhaust pump 83 are all installed on the vacuum box 1. The first vacuum gauge 81, the second vacuum gauge 82 and the exhaust pump 83 are all electrically connected to the controller 12. The detection end of the first vacuum gauge 81 is located in the vacuum box 1, the detection end of the second vacuum gauge 82 is located in the fourth space 64, and the exhaust end of the exhaust pump 83 is connected to the fourth space 64.

[0051] When the dipping rod 15 is removed, air enters the fourth space 64, and the operator starts the vacuum pump 83 and observes the controller 12 until the value of the second vacuum gauge 82 is consistent with the value of the first vacuum gauge 81, so that the vacuum degree of the fourth space 64 is consistent with the vacuum degree in the vacuum box 1, ensuring that the molten metal is kept warm and cast in a specific vacuum environment.

[0052] Reference Figure 2 and Fig.10 In order to reduce the heat loss of the molten metal inside the insulation furnace 13 and the temporary storage box 141, the insulation shell 9 is connected to the insulation furnace 13 and the temporary storage box 141. The liquid outlet of the smelting furnace 11 is located inside the insulation shell 9 on the insulation furnace 13, and the conveying port of the insulation furnace 13 is located inside the insulation shell 9 on the temporary storage box 141. A sampling port 91 is provided on the insulation shell 9, and a cover plate 92 is hinged at the sampling port 91. The cover plate 92 covers the sampling port 91. A baffle 93 is fixedly connected to the sampling port 91. In the initial state, the cover plate 92 is in a horizontal state and fits the baffle 93. A connecting spring 94 is welded between the sampling port 91 and the cover plate 92, and the cover plate 92 is located between the baffle 93 and the connecting spring 94. A feeding port 95 is fixedly connected between the insulation shell 9 and the vacuum box 1. The feeding port 95 extends to the outside of the vacuum box 1 and is connected to other feeding equipment.

[0053] The implementation principle of the vacuum directional solidification molding furnace with a segmented sampling device in the embodiment of the present application is as follows: when working, the operator inserts the dipping rod 15 into the limiting module 41 at the supplementary hole 21 in advance, uses the spring sheet 412 to press against the limiting ring groove to install the dipping rod 15, and then inputs the molten metal into the insulation furnace 13 and the continuous casting furnace 14 in turn, and then starts the moving motor 31 to rotate the moving screw rod 32 to move the nut block 34 to the top of the insulation furnace 13, and starts the lifting member 43 to make the nut block 34 move to the top of the insulation furnace 13. The rotating frame 2 is lowered to a specified height, and the lifting cylinder 441 is started until the clamping head is located between the two limiting flanges 51. Then, the rotating cylinder 443 is started to rotate the rotating disk 444, driving the rotating rail 445 to rotate, so that the two moving blocks 446 move toward the center of the rotating disk 444 at the same time, until the two limiting flanges 51 limit the clamping head, and the arc surface 52 is pressed against the side wall of the clamping head, and then the dipping rod 15 is lowered to separate the dipping rod 15 from the rotating frame 2 and press against the cover plate 92. , so that the cover plate 92 rotates counterclockwise, the connecting spring 94 is compressed, until the dipping rod 15 dips the molten metal on the insulation furnace 13, and then the dipping rod 15 is placed in the first space 61. Similarly, the molten metal in the temporary storage box 141 is dipped, and the dipping rod 15 is placed in the second space 62, and then the opening and closing cylinder 71 is started, and the two gates 66 are opened at the same time through the metal rope 72, so that the two dipping rods 15 fall into the third space 63, and then the dipping rod 15 passes through the fourth space 64 and the feeding port 65 in turn, and finally the controller 12 is observed, and the vacuum pump 83 is started until the vacuum degree in the fourth space 64 is consistent with the vacuum degree in the vacuum box 1, so as to achieve the effect of sampling and detecting the molten metal. If the content of each component in the molten metal in the temporary storage box 141 finally reaches the specified value, the continuous casting furnace 14 is directly started to cast the parts; if the content of each component in the molten metal does not reach the specified value, the corresponding metal is continued to be added through the feeding port 95 to continue smelting.

[0054] The operator utilizes the cooperation of the driving mechanism 4 and the dipping rod 15 to sample and test the molten metal in the holding furnace 13 and the temporary storage box 141 respectively. The detection of the molten metal in the holding furnace 13 is used to semi-precisely compensate for the metal content difference, while the detection of the molten metal in the temporary storage box 141 is used to fine-tune the metal content difference to ensure that the content of each component in the molten metal in the temporary storage box 141 reaches the specified value. Compared with the prior art, it is possible to make the formed metal reach the specified performance as much as possible, thereby improving the accuracy of molten metal smelting and the smelting effect of the smelting furnace.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
