Abstract

PURPOSE:To enhance machine capacity without using a hydraulic cylinder and, at the same time, to exclude the impact of upper and lower molds, by mounting a connection block for operating a toggle link, a connection rod for connecting said block to a drive part through an eccentric cam and the spring mounted between both of them and/or between the upper mold and a frame. CONSTITUTION:An eccentric cam 19 for rotating a motor rotates and a connection rod 17 is reciprocally moved by the rotation of said cam 19. Toggle link mechanisms 11, 12 are reciprocally moved by the reciprocating movement of the connection rod 17 to bring a lower mold 3 into contact with an upper mold 2. When a spring 18 is interposed to the connection rod 17, the action of spring force is started at a place approaching the upper dead point of the upper toggle link 11 and the molds are clamped softly with predetermined mold clamp force. At this time, when a spring 6 is also mounted in the upper mold 2, the spring force thereof participates in the mold clamp force.
