[0027] In this embodiment, the powder material for making the bowl shape is loaded into the powder filling barrel 202, and then the guide rod 204 can be compressed downward by the spring 301, so that the filling rod 208 passes through the connecting plate 205 and the connecting column 206 and approaches the opening of the mold cavity. Then, the guide rod 204 can be rotated by the crank 4 to rotate the scraper 207 that is in contact with the inner wall of the powder filling barrel 202, thereby stirring the internal material and sending it into the mold for making the bowl shape, ensuring the uniformity of the powder material, helping to prevent the powder material from agglomerating, and improving the fluidity and filling properties of the powder material. The rotation of the connecting plate 205 drives the filling rod 208 at the lower end of the connecting column 206 to rotate, so that the powder material filled in the mold cavity is evenly mixed and filled, thereby ensuring the uniformity and consistency of the powder material inside the final bowl-shaped crucible and ensuring that the powder material in the mold cavity is evenly distributed. The uniformity improves the quality and performance of the final product, avoids local looseness or uneven density, can increase the density of the powder, and improves the strength and durability of the final product. The upper and lower ends of the spring 301 are evenly provided with block plates connected to the inside of the cavity groove 3, and then the guide rod 204 is rotatably connected to the block plate. Then, when the guide rod 204 is compressed inside the cavity groove 3 through the spring 301, the movable rod 302 can be slid inside the powder bucket 202 and the support rod 201 to press the core 303 at the bottom end of the movable rod 302 downward, thereby compacting the powder filled in the cavity between the mold base 1 and the core 303, which helps to achieve uniform compaction of the powder in the cavity, avoids the problem of local looseness or uneven density, and plays an important role in improving the density, strength and durability of the product.

[0028] In a preferred embodiment, the stirring assembly includes a connecting plate 205 fixedly connected to the outer wall of the guide rod 204, the upper end of the connecting plate 205 is fixedly connected to a connecting column 206, the bottom end of the connecting column 206 is fixedly connected to a filling rod 208, and the lower end face of the connecting plate 205 is provided with a scraper 207. Through the rotation of the filling rod 208, the powder filled in the mold cavity is evenly mixed and filled, ensuring the uniformity and consistency of the powder inside the final bowl-shaped crucible, ensuring the uniform distribution of the powder in the mold cavity, and improving the quality and performance of the final product. Then, the scraper 207 attached to the inner wall of the powder barrel 202 is rotated to stir the internal material and send it into the bowl-shaped mold to ensure the uniformity of the powder, help prevent the powder from agglomerating, and improve the fluidity and filling properties of the powder.

[0029] In a preferred embodiment, the elastic component includes a cavity groove 3 opened inside the blanking block 203, and the upper and lower walls of the cavity groove 3 are provided with springs 301, and the upper and lower ends of the spring 301 are evenly provided with block plates connected to the interior of the cavity groove 3. When the guide rod 204 is compressed inside the cavity groove 3 through the spring 301, the movable rod 302 can be slid inside the powder loading barrel 202 and the support rod 201 to press the core 303 at the bottom end of the movable rod 302 downward, thereby compacting the powder filled in the cavity between the mold base 1 and the core 303, and then when the guide rod 204 is released, it can be ensured that the core 303 returns to its original position.

[0030] In a preferred embodiment, the discharge block 203 has a cone-shaped structure, and four groups of discharge pipes 8 are provided at the lower end of the powder barrel 202, which helps the material to flow to the discharge pipes 8 more quickly under the action of gravity. The design of the four groups of discharge pipes 8 can ensure that the material is evenly dispersed and output in the powder barrel 202, which helps in the subsequent filling process. The mold cavity can receive evenly distributed powder, avoiding the filling quality caused by uneven material distribution.

[0031] In a preferred embodiment, the upper end surface of the mold base 1 is connected with a screw rod 5, and the screw rod 5 is threadedly connected to the support plate 2. The inner wall of the support plate 2 is fixedly connected to the limiting block 6, and the front end of the limiting block 6 is fixedly connected to the driving plate 601. The top of the driving plate 601 is provided with a ejector pin 602. The mold base 1 is provided with a limiting groove 7 on the side close to the support plate 2. By rotating the screw rod 5, the support plate 2 is slid along the limiting groove 7 through the limiting block 6, so as to realize the upward movement of the support rod 201 on the support plate 2, thereby driving the powder barrel 202 and the bottom mold core 303 to separate from the mold base 1. At the same time, the driving plate 601 on the limiting block 6 drives the ejector pin 602 to move upward, pushing the bowl-shaped product formed inside the mold, reducing manual operation and labor intensity, and ensuring the smooth demolding of the product, avoiding product damage or deformation, and the overall operation is simple and convenient.

Then, the guide rod 204 can be rotated by the crank 4 to rotate the scraper 207 that is in contact with the inner wall of the powder loading barrel 202, thereby stirring the internal material and sending it into the bowl-shaped mold. The rotation of the connecting plate 205 drives the filling rod 208 at the lower end of the connecting column 206 to rotate, so that the powder material filled in the mold cavity is evenly mixed and filled, which can increase the density of the powder material. The upper and lower ends of the spring 301 are evenly provided with block plates connected to the inside of the cavity groove 3, and then the guide rod 204 is rotatably connected to the block plate. Then, when the guide rod 204 is compressed inside the cavity groove 3 by the spring 301, the movable rod 302 can slide inside the powder loading barrel 202 and the support rod 201, so as to press the mold core 303 at the bottom end of the movable rod 302 downward, thereby compacting the powder filled in the mold cavity between the mold base 1 and the mold core 303, which helps to achieve uniform compaction of the powder in the mold cavity, and then the design of the four groups of discharge pipes 8 can ensure that the material is evenly dispersed and output in the powder loading barrel 202;

[0034] By rotating the screw rod 5, the support plate 2 is slid along the limiting groove 7 through the limiting block 6, so that the support rod 201 on the support plate 2 moves upward, thereby driving the powder bucket 202 and the bottom mold core 303 to separate from the mold base 1. At the same time, the driving plate 601 on the limiting block 6 drives the ejector pin 602 to move upward, pushing the bowl-shaped product formed inside the mold, reducing manual operation and labor intensity, and ensuring smooth demoulding of the product, avoiding product damage or deformation, and the overall operation is simple and convenient.
