[0002] Silos are devices used to store raw materials, which ensure a stable supply of raw materials during mold processing. High-quality silo design can improve production efficiency and reduce production interruptions caused by raw material shortages.

[0003] During the production process of the assembly line, when the mold moves to the bottom of the silo, the staff can control the valve on the silo to open, so that a certain amount of material can enter the mold. Then, during the production process, due to the different sizes of the products produced, molds of different heights will be selected. However, when the mold is shorter, the discharge port of the silo will be far away from the mold, which will cause some of the material to be scattered to the outside when adding material to the mold, resulting in material waste, which will also cause the subsequent products to be unqualified.
