[0030] like Figure 2 and Figure 6 As shown, the cross-sectional shape of the positioning block 10 is a rectangle, and the positioning block 10 and the mold bottom plate 11 form a sliding structure, so that when the staff place the assembled mold bottom plate 11, the mold peripheral assembly 12 and the cylindrical mold inner core 13 on the carrier plate 7, they can be positioned by the positioning hole at the bottom of the mold bottom plate 11 and the positioning block 10;

[0031] like Figure 2 As shown, both sides of the bottom of the vibration box 1 are provided with second mounting grooves 16, and the interior of the second mounting grooves 16 is provided with a driving mechanism for driving the load-bearing plate 7 to rise and fall, the driving mechanism comprising two sets of electric push-pull rods 17, and the electric push-pull rods 17 are installed at the top of the interior of the second mounting grooves 16, the output end of the electric push-pull rods 17 is connected with a sliding connection block 18, and the sliding connection block 18 extends to the interior of the connection groove 9, the cross-sectional shape of the sliding connection block 18 is a "convex" shape, and the sliding connection block 18 and the connection groove 9 form a sliding structure, so that when the staff moves the load-bearing plate 7 to the bottom of the vibration box 1, the sliding connection block 18 can be inserted into the corresponding connection groove 9, and after the movement is completed, the electric push-pull rods 17 drive the sliding connection block 18 to move upward to complete the task of driving the load-bearing plate 7 to move upward, and the two sets of electric push-pull rods 17 can be controlled to act synchronously by a controller;

[0032] Example 2

[0033] like Figure 2 and Figure 3As shown, the inner wall of the vibration box 1 is evenly provided with first installation grooves 14, and a roller assembly 15 is installed inside the first installation groove 14. The end surface of the roller of the roller assembly 15 is substantially flush with the inner wall of the vibration box 1, and the connection flanges on the mold bottom plate 11, the mold peripheral assembly 12 and the cylindrical mold inner core 13 are matched with the inner side of the vibration box 1, so that after the bearing plate 7 drives the mold bottom plate 11, the mold peripheral assembly 12 and the cylindrical mold inner core 13 to enter the inner side of the vibration box 1, multiple groups of roller assemblies 15 can limit the separation direction of the two groups of mold peripheral assemblies 12, thereby ensuring the sealing of the connection during the subsequent vibration casting process, and during the rising process, the roller assembly 15 will rotate accordingly due to friction, avoiding unnecessary wear on the flange part;

[0034] like Figure 2 and Figure 3 As shown, a fixing mechanism for pressing the cylindrical mold core 13 is provided in the vibration box 1, and the fixing mechanism includes a pressing plate 19, which is installed on the inner wall of the vibration box 1, and a casting reserved hole 20 is opened on one side of the top of the pressing plate 19. The top of the mold base plate 11 is positioned by the positioning block 10, so that after the mold base plate 11, the mold peripheral assembly 12 and the cylindrical mold core 13 enter the vibration box 1, the casting port reserved on the cylindrical mold core 13 is aligned with the casting reserved hole 20, ensuring that the subsequent casting task can be completed. At the same time, the pressing plate 19 can cooperate with the supporting plate 7 to press the mold base plate 11, the mold peripheral assembly 12 and the cylindrical mold core 13 up and down, thereby further ensuring the sealing of the connection during the subsequent casting and vibration process.

[0035] The working principle of the utility model is as follows: firstly, two sets of mold peripheral assemblies 12 are assembled into a cylindrical shape and fixedly connected by bolts through the flanges thereon, so that the two sets of mold peripheral assemblies 12 can be separated when removing the mold and taking out the parts later, and then the mold bottom plate 11 and the cylindrical mold inner core 13 are respectively assembled and connected with the above-mentioned cylindrical mold through the flanges thereon;

[0036] After the above-mentioned splicing task is completed, the carrier plate 7 is slid out from the bottom of the vibration box 1 from the back to the front. At this time, the guide block 6 can slide in the first guide groove 4, and the sliding connection block 18 can slide in the connection groove 9 until the carrier plate 7 is completely detached from the vibration box 1. The carrier plate 7 is moved to the vicinity of the above-mentioned assembled mold through the universal wheel 8, and the positioning hole at the bottom of the mold bottom plate 11 and the positioning block 10 are matched to position the mold on the carrier plate 7. The carrier plate 7 can be provided with multiple sets of spare parts, which are convenient for alternating use, reducing the idle time of the vibration box 1 and increasing the overall work efficiency. Subsequently, the carrier plate 7 is moved by the universal wheel 8 so that the guide block 6 is aligned with the first guide groove 4 and inserted until the carrier plate 7 moves to the bottom of the vibration box 1. During this process, the sliding connection block 18 is inserted accordingly. The corresponding connecting groove 9 is then controlled by the controller to simultaneously drive the sliding connecting block 18 thereon to move upward, so that the carrying plate 7 can move upward accordingly, and the guide block 6 slides in the second guide groove 5 accordingly, until the mold bottom plate 11, the mold peripheral assembly 12 and the cylindrical mold inner core 13 completely enter the interior of the vibration box 1. At this time, the pressing plate 19 is attached to the top of the cylindrical mold inner core 13 and cooperates with the carrying plate 7 to press the mold bottom plate 11, the mold peripheral assembly 12 and the cylindrical mold inner core 13 up and down. At the same time, multiple groups of roller assemblies 15 limit the separation of the two groups of mold peripheral assemblies 12, thereby ensuring the stability of the mold bottom plate 11, the mold peripheral assembly 12 and the cylindrical mold inner core 13 assembly in the vibration box 1 and the sealing of the combined connection part;

[0037] After the above process is completed, the casting and molding task begins, such as the production of highly wear-resistant silicon carbide. The specific casting process is as follows;

[0038] 1. Add 2% graphite powder into the silicon carbide raw material and stir evenly, then add pure water in proportion and continue stirring until it becomes a slurry;

[0039] 2. Pour the slurry raw material into the gap between the mold peripheral assembly 12 and the cylindrical mold core 13 through the pouring reserved hole 20 and the pouring port on the flange of the cylindrical mold core 13, and at the same time turn on the vibration motor 2 on the vibration box 1 to perform the vibration task;

[0040] 3. After the pouring is completed, the electric push-pull rod 17 is controlled to drive the carrying plate 7 to descend to the lowest position, and then the mold bottom plate 11, the mold peripheral assembly 12 and the cylindrical mold core 13 and the casting parts therein are moved to the designated position through the carrying plate 7 for static curing;

[0041] 4. After the casting is solidified, the mold bottom plate 11, the mold peripheral assembly 12 and the cylindrical mold core 13 are removed and the appearance of the silicon carbide is checked. The places with pore defects are repaired. After completion, it is placed in an oven for sintering. The heating and cooling rates during the sintering process are controlled below 0.3°C / min. At the same time, it is kept warm at 110°C, 350°C and 1000°C. The heating and cooling rates and the insulation time are based on the specific thickness of the reference silicon carbide.

[0042] During the above steps 3 and 4, the vibration casting task can be continued by using the spare bearing plate 7 and the mold part in conjunction with the combined structure, thereby reducing the vacancy rate of the equipment and ensuring work efficiency.

[0043] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
