摘要：A mold clamping device comprises stationary plate (1), moving plate (2), mold-clamping cylinder (3), mold-moving cylinder (4), etc, wherein the mold-clamping cylinder(3) comprises two or more internal recycling cylinders with an extending single-piston-rod structure. The extending end of the piston rod is connected to the moving plate (2)or the stationary plate (1). A logic valve is provided between a piston (6) and a piston rod(5) in the cylinder body (7). As the valve core (10) of the logic valve moves right or left,the oil flow between the oil chamber with the piston rod (21) and the oil chamber withoutthe piston rod (22) ca be shut or resumed, which overcomes the defects of a largeamount of oil coming in and out of the oil chambers while opening or closing the mold aswell as the strong resistance. Furthermore, a partition board (8) can be provided in the oilchamber without the piston rod (22) so as to separate an empty chamber out to
communicate with the atmosphere, which avoids inhaling air due to the negative pressureoccurred when the mold opens.
