摘要： A casting method for forming a fastening part on an inclined plane of a casting may include mounting a plug unit including a casting plug and a screw thread insert combined with the casting plug on a movable mold or a fixed mold; performing casting by moving and combining the movable mold with the fixed mold and injecting a molten metal into a cavity formed between the movable mold and the fixed mold; performing mold opening after the casting; and separating the casting plug from the screw thread insert, wherein when the plug unit is mounted on the mold, the screw thread insert is deployed in the cavity, and a mold plane on which the casting plug is mounted forms an inclined plane having an acute angle against a horizontal plane that is parallel to a movement direction of the movable mold.

摘要： An exhaust heat recovery apparatus may include a bypass valve that is rotatably provided on a bypass path through which a high-temperature exhaust gas passes to open or close the bypass path, a heat exchanger that is communicatively connected to the bypass path to allow heat exchange to be performed between the high-temperature exhaust gas supplied from the bypass path and a low-temperature coolant introduced through a coolant inlet when the bypass path is closed, a valve actuator including a rod moved up and down by expansion or contraction of a wax sealed therein, and a connection part that converts an up and down motion of the rod into a rotary motion to allow the bypass valve to open or close the bypass path along with movement of the rod.
