A reciprocating drive apparatus for an automatic molding removing machine designed to remove a molded product from a molding machine by moving a chuck member, at least, in the longitudinal direction with a traveling member which is supported on a machine frame so as to be movable in the longitudinal direction. The reciprocating drive apparatus comprises a movable frame supported on the machine frame so as to movable in the longitudinal direction, the movable frame having a longitudinal dimension which is approximately half the distance of travel of the traveling member, a drive member for reciprocating the movable frame, a belt stretched between pulleys supported on two longitudinal end portions, respectively, of the movable frame, the belt having a portion thereof secured to the machine frame, and a movable member supported on the movable frame so as to be movable in the longitudinal direction, the movable member having a portion of the belt secured thereto and further having the traveling member attached thereto. Thus, when a molded product is automatically removed from the molding machine, it is possible to drive the chuck member to move horizontally through a distance which is approximately double the working stroke of the drive member and at a speed which is also approximately double the speed of the drive member. |
