Therefore, there is an urgent need for a mechanism that does not wear the linear bearings during vibration processing. Utility Model Content

[0005] Preferably, two lifting support pins are installed at the ends of the lifting plates on the left and right sides of the mold clamp body, and the lifting support pins can match with the hanging ears on the mold clamp body.

[0006] Preferably, the lifting support pin can rise simultaneously when the lifting cylinder performs the lifting action, and contact the hanging ear to lift the mold clamp as a whole. When the lifting cylinder performs the descending action, the mold clamp body can be fixed on the lifting support pin by its own weight. The mold clamp body reaches the mold closing position, which is fixed by the clamp body locating pin. The lifting cylinder continues to descend until the cylinder stroke ends, at which time the pin is completely separated from the hanging ear.

[0007] Preferably, the bracket includes an upper bracket and an intermediate support, wherein the upper end of the upper bracket is hinged to the bottom of the cylinder barrel of the lifting cylinder through a pin shaft, and the upper bracket is L-shaped and the intermediate support is installed at the lower end.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model adopts a cylinder to perform lifting, and the cylinder piston rod is connected to a floating joint. The floating joint can reduce the installation accuracy when the cylinder is installed. The floating joint is connected to the lifting plate. The left and right lifting plates are connected and fixed by four linear bearings, so that the lifting plates can run smoothly when moving up and down. The left and right side plates are connected to two lifting support pins, and the support pins match the hanging ears on the mold clamp. When the cylinder is lifted, the pins rise at the same time, and when the pins rise, they contact the hanging ears to lift the mold clamp as a whole. When the cylinder descends, the mold clamp is fixed on the pins by its own weight, and the mold clamp reaches the mold clamping position. The mold clamping position is fixed by the fixture body positioning pin, and the cylinder continues to descend until the cylinder stroke ends. At this time, the pins are completely separated from the hanging ears. When the fixture is vibrating, since the pins are completely separated from the hanging ears, the vibration cannot be transmitted to the execution guide rail and the linear slider, which solves the wear problem.

[0021] In this embodiment, the lifting support pin 15 can rise simultaneously when the lifting cylinder 10 performs the lifting action, and contact the hanging ear 21 to lift the mold clamp as a whole. When the lifting cylinder 10 performs the descending action, the mold clamp body 20 can be fixed on the lifting support pin 15 by its own weight. The mold clamp body 20 reaches the mold closing position, which is fixed by the clamp body locating pin. The lifting cylinder 10 continues to descend until the cylinder stroke ends, at which time the pin is completely separated from the hanging ear 21.
