The present invention provides an extrusion pin control device having a simple circuit structure and a die casting machine having the extrusion pin control device. The extrusion pin control device (30) has a pressurizing cylinder (40) and a detecting cylinder (50), wherein the pressurizing cylinder houses a pressurizing piston (41) for advancing and retracting an extrusion pin (42), and the detecting cylinder has a detecting piston (51) and detects a position by a position sensor (52). Further, by connecting a switching valve (60) and a switching valve (70), the pressurizing cylinder (40) andthe detecting cylinder (50) are switched to be connected in series and in parallel, and the flow direction of working oil is switched to the positive direction (forward) and reversed direction (backward).
