Article Preview

This study investigated on the cooling characteristics of AC4C aluminum alloy and AC7A aluminum alloy used as a casting material for manufacturing automobile tire mold by experiment. The metal mold device by gravity casting method was manufactured. AC4C casting material and AC7A casting material were heated in smelting furnace at about 650°C and 670°C, and then they injected into the metal mold device when the melting process was completely finished, respectively. When the melted casting material was completely injected into the metal mold device, the temperature inside the casting was measured by 9 measurement points. Also, when the temperature inside the casting was measured approximately 500°C during the cooling process, the casting is separated to metal mold device and carried out cooling at normal temperature. The separating time from metal mold device of AC4C casting material and AC7A casting material have been taken 25 minutes and 15 minutes, respectively. The final cooling time of AC4C casting material and AC7A casting material have been taken 400 minutes and 380 minutes, respectively. Accordingly, AC7A casting material is able to improve on productivity than AC4C casting material because production time was decreasing.
