Abstract

This application discloses a bottom-pouring casting system, relating to the field of casting technology. The system includes a hopper and a sand mold. The hopper is divided into a storage hopper and a casting hopper. A partition separates the storage hopper and the casting hopper. A through-hole is provided on the partition near the bottom of the hopper. A baffle is provided inside the casting hopper, and a flow-blocking plate is slidably engaged between the baffle and the partition. A casting hole is provided at the bottom of the casting hopper. By separating the hopper with the partition, molten iron is temporarily stored in the storage hopper, allowing slag to float to the surface of the molten iron. The through-hole allows molten iron to be transported from the bottom of the hopper, preventing the upper layer of slag from affecting the casting quality. The flow-blocking plate blocks the through-hole, preventing the flow of molten iron when not being cast, facilitating the storage of molten iron in the storage hopper. The baffle engages the flow-blocking plate, facilitating its fixation and movement. The casting hole allows molten iron to flow out from the bottom of the casting hopper for casting.
