A motor-operated cylinder is provided, wherein the rotational movement of the output shaft of a motor is converted into a linear movement by a thread mechanism,with the least possible load applied to the thread mechanism,when an object starts to be moved. The motor-operated cylinder is equipped with a booster,so that propelling forces exerted by both the thread mechanism,and booster,simultaneously act on a retractable rod

Motor-driven cylinder

A simplified apparatus of cooling lines is disclosed. A plurality of cooling lines (Z.sub.1 -Z.sub.4) are disposed between two parallel lines, a teeming line (X) and a mold-removing line (V). A mold sending-in line (Y) is disposed to connect the end portion of the teeming line and the starting portions of the cooling lines. A mold sending-out line (U) is disposed to connect the end portions of the cooling lines and the starting portion of the mold-removing line (V). A first transfer device (4) runs along the mold sending-in line (Y), while a second transfer device (6) runs along the mold sending-out line (U). Opposing electric servo-cylinders (15, 29) are mounted on a transfer truck (9) of the first transfer device (4) and a transfer truck (23) of the second transfer device (6).
