摘要

An elevating mechanism of a bottom mould is provided in the invention. The mechanism is mounted on a bottle blowing machine and comprises an elevating rod movable in up-down direction. The bottom mould is mounted on the upper end of the elevating rod. The elevating mechanism also comprises a rotation shaft rotatable around an axis of rotation, a protrusion 3 fixedly connected with the rotation shaft, a driving mechanism for driving the rotation of the rotation shaft, and a sliding block fixedly connected on the elevating rod. A guiding groove is opened on the protrusion, and the sliding block is slidably inserted into the guiding groove. In the invention, a protrusion having a guiding groove on it's surface and a sliding block fixedly connected on the elevating rod are utilized, such that the elevating rod can move in up-down direction when the sliding block slides along the guiding groove. The elevating mechanism of the invention is simple in configuration and convenient in operation.
