[0026] like Figure 1-4As shown, in this embodiment, a metal casting device capable of precisely controlling the casting flow rate and speed includes a casting device and a conveying mechanism. The casting device includes a frame 1, which serves as the supporting structure for the entire casting device, ensuring the stability of the installation of each component. A receiving box 2 is provided at the top of the frame 1 to store the molten metal to be cast. An output channel 3 is connected to the bottom of the receiving box 2, through which the molten metal flows to the casting position below. A rod 4 is slidably arranged inside the output channel 3, with a blocking block 5 installed at the bottom end of the rod 4. The blocking block 5 cooperates with the opening 6 at the end of the output channel 3. By moving the rod 4 up and down, the opening and closing of the opening 6 is controlled, thereby controlling whether the molten metal flows out. In this embodiment, the conveying mechanism is a belt conveyor.
[0027] In this embodiment, a drive adjustment mechanism is connected to the upper end of the rod 4. This mechanism is used to precisely control the movement of the rod 4, thereby precisely adjusting the opening of the opening 6 to control the casting flow rate and speed. The drive adjustment mechanism includes a housing 7, inside which a sliding body 8 is vertically slidably arranged. Two toothed plates 9 with different tooth densities are symmetrically arranged in the longitudinal direction of the sliding body 8. On the outer sidewall of the housing 7, a notch 10 is provided corresponding to the position of each toothed plate 9. On the outer side of the housing 7, a drive motor 11 is installed at the position of each notch 10. A drive gear 12 is installed at the output end of each drive motor 11, and the drive gear 12 meshes with the corresponding toothed plate 9. When the position of rod 4 needs to be adjusted, different drive motors 11 are started. Drive motor 11 drives drive gear 12 to rotate. Since the toothed plate 9 meshes with drive gear 12, the toothed plate 9 drives the sliding body 8 to slide vertically in the housing 7. The bottom of the sliding body 8 is connected to the top of rod 4, thereby realizing the precise adjustment of the position of rod 4, and finally realizing the precise control of the opening 6 of output channel 3, so as to achieve the purpose of precise control of casting flow and speed.
[0028] In this embodiment, to ensure the installation stability of the drive motor 11, a support frame 14 is fixedly installed on the outside of the housing 7 at the positions corresponding to each notch 10, and the drive motor 11 is mounted on the support frame 14. This installation method makes the drive motor 11 more stable during operation and reduces the impact of vibration and other factors on the drive adjustment accuracy.
[0029] In this embodiment, to ensure the smoothness and accuracy of the vertical sliding of the slider 8 within the housing 7, several guide strips 15 are vertically arranged on the outer wall of the slider 8, and grooves 16 are provided on the inner wall of the housing 7 corresponding to the positions of each guide strip 15. The guide strips 15 and the grooves 16 cooperate with each other to limit the offset of the slider 8 during the sliding process, ensuring that the slider 8 can move accurately in the vertical direction, thereby ensuring the precision of the position adjustment of the rod 4.
[0030] In this embodiment, considering the temperature maintenance of molten metal during storage and transportation, a heat insulation cover 17 is provided on the outside of the container 2. The heat insulation cover 17 can effectively reduce the heat loss of molten metal in the container 2, maintain the temperature of molten metal within a suitable casting range, ensure the fluidity of molten metal, and help improve casting quality.
[0031] In this embodiment, a plurality of platforms are arranged on the conveying mechanism, and the platforms are used to place the casting molds. Each platform includes a base plate 18, and a weighing sensor 19 is arranged on the upper part of the base plate 18. The weighing sensor 19 can monitor the weight changes of the casting mold placed on the platform and the molten metal inside the mold in real time. By comparing it with a preset weight value, the sensor feeds back to the control system, thereby making more precise adjustments to the casting flow rate and speed to ensure that the amount of molten metal cast in each mold meets the requirements.
[0032] In this embodiment, to achieve accurate identification and corresponding operation of different casting molds, an RFID reader 20 is provided at the opening 6, and an RFID chip 21 is provided on the platform. When the platform moves below the opening 6 with the conveying mechanism, the RFID reader 20 can read the mold information stored in the RFID chip 21 on the platform, such as mold type and required casting parameters. The control system automatically adjusts the working parameters of the drive adjustment mechanism and other components according to the information read, so as to realize personalized casting operation for different molds.
[0033] In this embodiment, a collection box 22 is also provided below the opening 6 to collect excess molten metal generated during the casting process. An eddy current electric heating device 23 is provided at the bottom of the collection box 22. The eddy current electric heating device 23 can heat the molten metal in the collection box 22 to keep it in a liquid state, which is convenient for subsequent recycling.
[0034] In this embodiment, the bottom of the output channel 3 is bifurcated with two discharge pipes 24, one of which corresponds to the collection box 22, and the other corresponds to the platform on the conveying mechanism. A distribution mechanism is provided at the junction of the two discharge pipes 24. The distribution mechanism includes a horizontally arranged rotating shaft 25, on which a flap 26 is provided. One end of the rotating shaft 25 is connected to the output end of the second drive motor 27. By rotating the second drive motor 27 in both directions, the rotating shaft 25 is driven to rotate, thereby causing the flap 26 to rotate, thus controlling the flow direction of the molten metal, that is, controlling whether the molten metal flows to the collection box 22 or to the platform on the conveying mechanism, so as to reasonably distribute the molten metal under different working conditions, such as normal casting, pipe cleaning, etc.
[0035] The working principle and beneficial effects of the above technical solution are as follows:
[0036] During use, the molten metal to be cast is poured into the container 2. Due to the effect of the heat insulation cover 17, the temperature of the molten metal is maintained. The platform moves to the bottom of the opening 6 with the conveying mechanism. The RFID reader 20 at the opening 6 reads the information of the RFID chip 21 on the platform. The control system reads information such as the mold type and the required casting volume to ensure that the casting parameters match the mold.
[0037] During casting, the corresponding drive motor 11 is activated by the control system. Drive motor 11 drives drive gear 12 to rotate, which meshes with toothed plate 9, causing sliding body 8 to slide within housing 7. This, in turn, moves rod 4, adjusting the opening of the block 5 and the outlet channel 3 opening 6, thus precisely controlling the outflow rate and speed of the molten metal. By setting multiple toothed plates with different tooth densities and corresponding drive motors and drive gears, multi-level precise adjustment of the rod position can be achieved, thereby precisely controlling the opening of the outlet channel and ultimately achieving precise control of the casting flow rate and speed. Weighing sensor 19 on the platform monitors the weight change of the molten metal in the mold in real time and feeds it back to the control system. The control system adjusts the drive adjustment mechanism according to the weight change to ensure accurate casting volume.
[0038] During the casting process, if excess molten metal is generated, the drive motor 27 rotates the shaft 25, causing the flap 26 to rotate and guide the molten metal to the collection tank 22. The eddy current electric heating device 23 at the bottom of the collection tank 22 heats the collected molten metal to keep it in a liquid state for subsequent recycling.
[0039] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
