The hydraulic cylinder 19 is a double-acting single piston rod hydraulic cylinder, and the piston rod of the hydraulic cylinder 19 extends out or retracted, the drive mechanism moves along the horizontal guide rail; the left and right vertical guide rails 14 are fastened to the left and right side plates 23 by screws 13, and the vertical slider 12 is set on the vertical guide rail 14, and the two are fitted with a sliding clearance The roller seat 9 is fixed on the vertical slider 12 by the screw 8, the roller 10 is equipped with a bearing, the inner ring of the bearing is in transition fit with the pin shaft 11, and the outer ring of the bearing is in transition fit with the roller 10. The pin shaft 11 connects the bearing and the roller 10 with the roller housing 9 . The rectangular frame 7 is located below the roller 10 , and the roller 10 falls on the upper surface of the rectangular frame 7 under the action of gravity and rolls on the rectangular frame 7 .

Referring to Fig. 2 and Fig. 3, a pair of ear plates 5 are welded at both ends of the rectangular frame 7, and the guide post 4 is hinged with the ear plate 5 through the pin shaft 6; the guide post 4 is connected with the piston rod of the cylinder 3 through threads; Fastened below the flat plate 1 of the workbench, the cylinder 3 is positioned at the front and rear sides of the horizontal linear guide rail 25 . Through the extension and retraction of the piston rod of the cylinder 3, the lowering and raising of the rectangular frame 7 is driven, thus driving all the rollers 10 on the rectangular frame 7, the pin shaft 11, the roller seat 9 and the vertical slider 12 together Descend and raise, make the vertical slider 12 retract under the workbench plate 1 or stretch out above the workbench plate 1.

At the origin position of the mold clamping, the piston rod of the cylinder 3 retracts into the cylinder 3, driving the rectangular frame 7 to rise, and the roller 10 falling on the rectangular frame 7 drives the roller seat 9 to rise together, therefore, the vertical The slide block 12 also rises, stretches out the workbench plane from the two parallel long holes of the workbench plate 1, stretches into the long groove below the formwork, and retracts the piston rod of the hydraulic cylinder 19 along the horizontal direction to drive The whole mechanism moves horizontally, that is, the vertical slider 12 drives the modules fixed on the formwork to move in the horizontal direction together. When the two modules moving relative to each other are merged together, the hydraulic cylinder 19 stops shrinking, and the vertical slider 12 also stops. Movement; the piston rods of the two cylinders 3 are elongated, driving the rectangular frame 7 to descend, and the roller 10, pin shaft 11, roller seat 9 and vertical slider 12 falling on the rectangular frame 7 are under the action of gravity, The rectangular frame 7 descends together, and the vertical slide block 12 is retracted under the flat plate 1 of the workbench.
