Description

Conveyor System for Cooling and Conveying Molten Metal The present invention relates to a conveyor system for cooling and transporting molten metal, and more specifically, to a conveyor system for cooling and transporting molten metal designed to allow cooling to be performed while continuously transporting the mold in a circulating manner in a process of precision casting by injecting high-temperature molten metal into a mold, and subsequently demolding and transporting the cast product by gravity. In the casting process, the cooling and demolding of molten metal after it has been poured into a mold or die is a critical step that determines product quality and productivity. Previously, it was common practice to handle molds manually at a fixed location or to perform repetitive tasks by operating each stage of injection, cooling, and demolding with separate equipment. This method is prone to product variations depending on the operator's skill level and changes in conditions, and it is difficult to ensure uniformity in the time required for transfer and cooling, which can lead to defects such as uneven cooling, internal porosity, and shrinkage cavities. In addition, maintaining a consistent mold arrangement and uniform speed is essential for the stable transport and cooling of high-temperature molten metal, but existing systems can lead to reduced cooling efficiency and deterioration of product quality due to interference between molds, vibration, and overheating. Furthermore, demolding after casting is mostly performed manually or with mechanical demolding machines, which has caused problems such as damage to castings, alignment errors, and production delays. Therefore, there is an increasing demand for integrated solutions in which the injection, cooling, transfer, and demolding of molten metal can be performed automatically in a single continuous system. In particular, it is necessary to secure a structure capable of high-speed circulation while maintaining stable durability even under repetitive thermal shock, as well as mold arrangement and transfer control technologies that can guarantee cooling efficiency.
