Detailed Description
As shown in fig. 1 to 3, a hydraulic clamp structure for clamping a mold includes a clamp body 1, a pressing plate 3 movably connected to the clamp body 1 through an axis 2 and disposed on the top of the clamp body 1, and a reset mechanism and a driving mechanism disposed in the clamp body 1 and connected to the pressing plate 3, wherein the driving mechanism includes a cylinder 4 mounted in the clamp body 1 and a piston 5 disposed in the cylinder 4, the two ends of the pressing plate 3 are respectively a movable connecting portion 31 and a movable clamping portion 32, the end of the piston 5 penetrates through the clamp body 1 and abuts against the movable connecting portion 31 of the pressing plate 3, and the movable clamping portion 32 of the pressing plate 3 is close to the mold;
the reset mechanism comprises an installation channel 6 installed in the fixture body 1 and a reset spring 7 arranged in the installation channel 6, the end part of the reset spring 7 penetrates out of the fixture body 1 and is connected with the pressing plate 3, and the connecting point of the reset spring 7 and the pressing plate 3 and the movable clamping part 32 are respectively positioned on two sides of the axis 2.
Further, the bottom of the clamp body 1 is provided with a guide rail seat 8, the side surface of the clamp body 1 is provided with a push-pull handle 9, and the push-pull handle 9 controls the clamp body 1 to slide on the guide rail seat 8. A proximity switch 10 is arranged on one side, close to the die, of the fixture body 1, a clamping indication board 11 is installed at the top of the cylinder body 4, and a dust cover 12 is installed at the top of the fixture body 1.
