Abstract
The utility model discloses a servo-drive vertical mold assembling device which comprises a base, a movable base located above the base and a lower movable frame located below the base. A lower mold is connected to the upper end of the base. An upper mold corresponding to the lower mold is connected to the lower end of the movable base. Pull rods are connected to the lower movable frame and upwards extend to penetrate through the base to be connected with the movable base. A helical mechanism and connecting rod mechanisms are connected between the lower movable frame and the base. The helical mechanism comprises a threaded rod and a sliding block which are connected through a helical pair. The threaded rod is vertically connected to the base in a rotary mode and connected with a servo-drive prime motor in a transmission mode. Each connecting rod mechanism comprises an upper rod, a lower rod and a toggle rod. One end of each upper rod is hinged to the base, the other end of the upper rod, one end of the corresponding lower rod and one end of the corresponding toggle rod are hinged to one position, the other end of the toggle rod is hinged to the sliding block, and the other end of the lower rod is hinged to the lower movable frame. When the servo-drive vertical mold assembling device is located at the mold assembling position, due to the fact that the sliding block is connected with the helical pair of the threaded rod, mold assembling force between the molds still exists after the prime motor stops work, and energy consumption is reduced.
