LINKAGE MECHANISM BETWEEN UNIAXIAL DIE OPENING AND CLOSING AND BOTTOM DIE LIFTING

摘要

A linkage of mould opening and closing and bottom mould elevating is provided in the invention. The linkage comprises a mould opening and closing assembly, an elevating assembly and a driving assembly for driving the movement of the mould opening and closing assembly and the elevating assembly. The mould opening and closing assembly comprises a bottom mould, a fixed mould plate disposed on the machine frame of the bottle blowing machine, and a moving mould plate cooperating with the fixed mould plate. The elevating assembly comprises a protrusion, an elevating rod and a sliding block fixed on the lower portion of the elevating rod. A sliding groove extending in up-down direction is opened on the protrusion, and the sliding block is slidably disposed in the sliding groove. The bottom mould is fixed on the upper end of the elevating rod. The driving assembly comprises a rotation shaft rotatable around its' shaft axis, a driving source for driving the rotation of the rotation shaft. The moving mould plate and the protrusion are fixedly connected with the rotation shaft. The linkage of the mould opening and closing assembly and the elevating assembly are driven by one rotation shaft. Thus, the driving is achieved by a simple configuration, and the whole device of the invention is simple in structure and convenient in operation.
