PURPOSE: A composite link opening and closing device for multiple dies is provided to simultaneously open and close a lot pairs of dies with the same stroke. CONSTITUTION: A composite link opening and closing device for multiple dies comprises: a mobile plate linearly moving on a mobile template(220); a fixed plate(110) fixed on a fixed template(230) by a fixing member(240); at least one of middle plates(120) installed between the mobile plate and the fixed plate; a guider supporting the linear movement of the mobile plate and the middle plate; and a composite link opening and closing unit(140) connecting the mobile plate with the middle plate and the middle plate with the fixed plate. The opening and closing unit interlock links A,B,C and D(141-144) having partial gears(145). As the opening and closing unit is engaged by the partial gears, the links are operated in the same angle. The middle plate and the mobile plate are simultaneously operated in a distance ratio of 1:2. Therefore, dies are opened and closed in the same stroke and speed.
