PROBLEM TO BE SOLVED: To eliminate the anxiety that, in a die casting machine, the burrs of a metallic material, a misty liquid or the like are stuck to a rotation transfer system of transferring the rotation of a motor for extrusion to a ball screw mechanism and to the ball screw mechanism, and also, to attain low noise. SOLUTION: In the die casting machine, a rotation transfer system for transferring the rotation of a motor for extrusion as a driving source of moving an extrusion plate forward and backward to a ball screw mechanism, and the ball screw mechanism are stored in a sealing structure.
