[0024] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Before pouring, a mold baffle needs to be installed at the mold opening to prevent molten metal from flowing out during the pouring process. After casting is complete, the baffle needs to be removed before taking the casting out of the mold. See also Figure 1A mold baffle loading and unloading device is disclosed for loading and unloading mold baffles during the production process. It includes a fixed bracket 100, a rotating bracket 200, a rotating shaft assembly 300, and a baffle mounting rod 400. The fixed bracket 100 is fixedly connected to the body 1 of a casting centrifuge; the rotating bracket 200 is rotatably connected to the fixed bracket 100; the rotating shaft assembly 300 is rotatably connected to the rotating bracket 200; the baffle mounting rod 400 has a first end 410 and a second end 420 in the length direction, the first end 410 for supporting the mold baffle 2, and the second end 420 for applying force; the rotating shaft assembly 300 is rotatably connected to the baffle mounting rod 400, the connection position of the two being between the first end 410 and the second end 420, and relatively close to the first end 410.

[0026] The aforementioned mold baffle loading and unloading device is installed on the body 1 of the casting centrifuge. In use, the fixed bracket 100 is installed on the body 1, the rotating bracket 200 can rotate freely relative to the fixed bracket 100, and the rotating shaft assembly 300 can rotate freely relative to the rotating bracket 200, thereby adjusting the relative position of the baffle mounting rod 400 and the mold baffle 2. Furthermore, the mold baffle loading and unloading device, by providing a baffle mounting rod 400 with a first end 410 and a second end 420, and using the rotating shaft assembly 300 as a fulcrum to form a "lever," allows for easier movement of the mold baffle 2 carried by the first end 410 by applying force to the second end 420 and adjusting its position. This configuration allows for easier movement of the mold baffle 2 and facilitates its disassembly and installation, further improving work efficiency.

[0027] It should be noted that the weight of the mold baffle 2 should be evaluated before design. The relative position of the rotating shaft assembly 300 and the baffle mounting rod 400 during installation should be determined by lever principle to save effort.

[0028] See also Figure 1 In one embodiment, the rotating shaft assembly 300 includes a rotating bushing 310 rotatably connected to the fixed bracket 100, a height adjustment bracket 320 slidably connected inside the rotating bushing 310, and a fixing pin 330; the rotating bushing 310 has a plurality of positioning holes 311 along its length, and the height adjustment bracket 320 has a fixing hole 321; the fixing pin 330 passes through the positioning holes 311 and the fixing hole 321 to fix the relative position of the height adjustment bracket 320 and the rotating bushing 310.

[0029] The rotating bushing 310 of the aforementioned mold baffle loading and unloading device is rotatably connected to the rotating bracket 200. The height adjustment bracket 320 is inserted into the rotating bushing 310, and the relative position of the height adjustment bracket 320 and the rotating bushing 310 can be fixed by the fixing pin 330. In this way, the height of the rotating shaft assembly 300 can be adjusted to adapt to different needs. It should be noted that the rotating bushing 310 is rotatably connected to the rotating bracket 200 in ways including but not limited to using a bearing connection.

[0030] See also Figure 1 In one embodiment, a locking sleeve 430 is fitted on the baffle mounting rod 400, and the locking sleeve 430 has a locking end 431; the rotating shaft assembly 300 also includes a locking mechanism 340, which cooperates with the locking end 431 to fix the relative position of the baffle mounting rod 400 and the rotating shaft assembly 300.

[0031] The locking mechanism 340 of the aforementioned mold baffle loading and unloading device is fixed on the height adjustment bracket 320, and the locking sleeve 430 is fitted onto the baffle mounting rod 400 and can move forward and backward. When the baffle mounting rod 400 is in a certain position, it pushes the locking sleeve 430 forward, and the locking sleeve 430 is locked and fixed with the locking device on the locking mechanism 340. In this way, it can be ensured that the mold baffle 2 will not fall off in the free state, reducing the possibility of safety problems.

[0032] See Figure 1 In one embodiment, one end of the locking mechanism 340 is provided with an opening slot, which is configured to provide a movement channel for the locking end 431; the locking end 431 cooperates with the opening slot to lock the relative position of the locking sleeve 430 and the locking mechanism 340. (See also...) Figure 2 and Figure 3 The locking mechanism 340 has a U-shaped opening groove 341 at the end furthest from the height adjustment bracket 320. The cross-section of the U-shaped opening groove 341 is a convex conical T-shaped groove 342. Correspondingly, the locking end 431 of the locking sleeve 430 is a T-shaped end adapted to the conical T-shaped groove 342, with a pin hole near the T-shaped end for locking via a locking pin 432. It should be noted that the opening groove can be other shapes besides U-shaped (341), as long as it provides a moving channel for the locking end 431 and mates with it.

[0033] In practical use, when the mold baffle 2 is hooked onto the hook of the baffle mounting rod 400, the locking end 431 of the locking sleeve 430 is pushed into the U-shaped opening groove 341 at the front end of the locking mechanism 340. Under the weight of the mold baffle 2, the locking mechanism 340 holds the baffle mounting rod 400 in place, preventing rotation. A locking pin 432 is inserted into the locking sleeve 430, locking it into the conical T-groove 342 of the locking mechanism 340, ensuring that the locking sleeve 430 cannot disengage from the conical T-groove 342. This prevents the locking sleeve 430 from disengaging due to vibrations or movement during operation, thus avoiding safety issues. When preparing to install the mold baffle 2, the locking pin 432 is pulled out, and the locking sleeve 430 is pushed out from the U-shaped opening groove 341 at the front end of the locking mechanism 340. The position of the baffle mounting rod 400 is then adjusted before inserting the mold baffle 2.

[0034] In one embodiment, the rotating shaft assembly 300 further includes a locking mechanism 340, which is connected to the baffle mounting rod 400 via an elastic element. The connection position between the elastic element and the baffle mounting rod 400 is located between the connection position and the second end 420. It should be noted that this connection position refers to the connection position between the rotating shaft assembly 300 and the baffle mounting rod 400.

[0035] In one specific embodiment, the elastic element is a tension spring 500.

[0036] It should be noted that due to the large mass of the mold baffle 2, when the mold baffle 2 detaches from the mold, the second end 420 of the baffle mounting rod 400 will generate an upward force under the action of its gravity. A tension spring 500 connects the baffle mounting rod 400 and the locking mechanism 340. This ensures that when the second end 420 of the baffle mounting rod 400 is lifted instantaneously, the reaction force of the tension spring 500 provides a buffered tension on the baffle mounting rod 400, preventing potential safety hazards. Simultaneously, the tension of the tension spring 500 also provides a assistive force when operating the baffle mounting rod 400, reducing the operational intensity. In specific designs, the required tension and installation position of the tension spring 500 can be calculated as needed.

[0037] In one embodiment, the first end portion 410 is a hook portion for suspending the mold baffle.

[0038] In one embodiment, the fixed bracket 100 includes a first fixed bracket 110 and a second fixed bracket 120 arranged along the height direction of the body 1; the rotating bracket 200 includes an upper connecting plate 210, a lower connecting plate 220, and a longitudinal connecting beam 230 connecting the upper connecting plate 210 and the lower connecting plate 220 together; the upper connecting plate 210 is connected to the first fixed bracket 110 through a first rotating shaft 111; the lower connecting plate 220 is connected to the second fixed bracket 120 through a second rotating shaft 121.

[0039] This invention also provides a method for loading and unloading a mold baffle. The mold baffle 2 is disassembled using a mold baffle loading and unloading device, including an installation method. The specific steps of the installation method include: determining the relative position of the mold opening and the machine body 1, and fixing the fixing bracket 100 to the machine body 1; rotating the rotating bracket 200 and adjusting the rotating shaft assembly 300 so that the first end 410 of the baffle mounting rod 400 is adjacent to the installation position of the baffle to be installed; suspending the mold baffle 2 to be installed to the first end 410 of the baffle mounting rod 400; adjusting the position of the second end 420 of the baffle mounting rod 400 to push the mold baffle 2 into the mold opening; and readjusting the position of the second end 420 of the baffle mounting rod 400 again so that the first end 410 is detached from the mold baffle 2, thus completing the installation process. The above-mentioned mold baffle loading and unloading method is convenient and labor-saving, further improving work efficiency.

[0040] This invention also provides a method for loading and unloading a mold baffle. The mold baffle 2 is disassembled using a mold baffle loading and unloading device, including the following steps: rotating the rotating bracket 200, adjusting the second end 420 of the baffle mounting rod 400 so that the first end 410 hooks onto the baffle; and readjusting the second end 420 of the baffle mounting rod 400 again to disengage the baffle from the mold opening. This mold baffle loading and unloading method is convenient and labor-saving, further improving work efficiency.

[0041] Specifically, in one embodiment, when the mold baffle loading and unloading device is installed, the relative position of the mold opening and the machine body 1 needs to be determined first, the fixed bracket 100 (first fixed bracket 110, second fixed bracket 120) is fixed to the machine body 1, and the other components of the mold baffle loading and unloading device are installed on the fixed bracket 100 through the rotating shaft (first rotating shaft 111, second rotating shaft 121) to ensure that they can rotate freely.

[0042] When installing the baffle, first adjust the height of the height adjustment bracket 320 to ensure that the hook of the baffle mounting rod 400 is approximately at the installation position of the mold baffle 2. Then, hang the mold baffle 2 on the hook of the baffle mounting rod 400, which is locked by the locking sleeve 430 and the locking mechanism 340. Push the mold baffle loading / unloading device to the mold opening, open the locking mechanism 340, adjust the position of the other end of the baffle mounting rod 400, and push the mold baffle 2 into the mold opening. Lift the second end 420 of the baffle mounting rod 400 to disengage the hook from the mold baffle 2; the installation process is now complete.

[0043] After installation, rotate the mold baffle loading and unloading device to a safe position and lock it.

[0044] When it is necessary to remove the mold baffle 2, rotate the mold baffle loading and unloading device to the mold opening position, adjust the second end 420 of the baffle mounting rod 400 so that the first end 410 hooks onto the mold baffle 2, and pull the mold baffle loading and unloading device to disengage the mold baffle 2 from the mold opening. Due to the weight of the mold baffle 2, the second end 420 of the baffle mounting rod 400 will rotate upward. Since a tension spring 500 is installed on the baffle mounting rod 400, the baffle mounting rod 400 will not rotate a large distance under the tension of the tension spring 500, and at the same time, it assists in pressing the baffle mounting rod 400 downward, making the operation convenient. After removing the mold baffle 2, push the locking sleeve 430 into the locking mechanism 340 at a certain position to lock it. The removal process is complete. Rotate the mold baffle loading and unloading device to a safe position and lock it.
