2. when the lifting oil cylinder is lifted, the abnormal bounce and the asynchronous lifting are realized.

In order to solve the technical problem, the utility model discloses a realize according to following mode: a mould lifting slide rail comprises a slide rail body, wherein a plurality of transversely uniformly arranged grooves are formed in the surface of the slide rail body, and roller assemblies are arranged in the grooves; the roller assembly comprises a roller shaft, a roller and rolling bearings, the roller is hollow, the rolling bearings are mounted in the roller, and the roller shaft penetrates through the rolling bearings to be connected to two sides of the groove; the slide rail is characterized in that a lifting oil cylinder is arranged at the bottom of the slide rail body, a plurality of pistons which are transversely arranged uniformly are arranged in the lifting oil cylinder, and a supporting shaft is arranged in each piston.

Further, the rolling bearing is a ball bearing.

Further, the ball bearing is a carbon steel ball bearing.

Further, the outer diameter of the support shaft is smaller than the inner diameter of the piston.

Further, one end of the support shaft is connected to the top of the piston, the other end is parallel to the bottom of the piston, and the other end is at the same height as the bottom of the piston.

As described above, the utility model discloses a lift mould slide rail, after having installed ball bearing in the gyro wheel, make it possess autonomic lubricating function, it is dead to produce the card when can avoiding using for a long time, has solved heavy mould effectively and has removed the problem that is out of order and can't freely remove. After the supporting shaft is installed in the piston, when the piston is in contact with the contact surface in the lifting process, the lifting stress point of the piston generated in the lifting process is guided, and the abnormal problem that the single-side inclined warping head of the whole lifting die slide rail is enabled to be bounced abnormally when the lifting is carried out is solved.
