The invention discloses a single open mold and bottom mold lifting linkage mechanism of a bottle blowing machine. The single open mold and bottom mold lifting linkage mechanism comprises a mold frame support, a fixed side mold, a mold opening and closing rotating shaft capable of rotating around a first axis line and arranged on the mold frame support, a bottom mold support capable of rotating around a second axis line and arranged on the mold frame support, a driving rotating shaft capable of rotating around a third axis line and arranged on the mold frame support, a movable side mold arranged on the mold opening and closing rotating shaft, a bottom mold guide rail arranged on the bottom mold support, a bottom mold sliding block arranged on the bottom mold guide rail, a first linkage assembly arranged between the driving rotating shaft and the movable side mold, a second linkage assembly arranged between the driving rotating shaft or the movable side mold and the bottom mold support, a first rotor arranged on one of the bottom mold sliding block and the fixed side mold, and a space cam arranged on the other one of the bottom mold sliding block and the fixed side mold, wherein the space cam is provided with a cam curve positioned in an arc surface; the heights of the two ends of the cam curve are different; and the first rotor can be arranged on the space cam in a rolling manner along a groove or a flange of the cam curve. The single open mold and bottom mold lifting linkage mechanism of the bottle blowing machine is simple in structure, and parts are not prone to wear and tear.
Description
technical field [0001] The invention relates to the technical field of bottle blowing, in particular to a single mold opening and bottom mold lifting linkage mechanism of a bottle blowing machine. Background technique [0002] The bottle blowing machine is the key equipment for producing various plastic bottles for liquid packaging. The blow molding machine has strict requirements for each process and high requirements for mutual cooperation, especially for the synchronous control of the opening and closing movement of the single mold side mold and the swinging movement of the bottom mold. strict. [0003] In the existing bottle blowing machine, a composite mechanism is formed by a cylindrical cam and a space link mechanism. The space link mechanism is used to realize the swing of the bottom mold, and the swing bottom mold is synchronously lifted and lowered under the drive of the cylindrical cam. Mechanism advantages: simple mechanism and few moving parts. Disadvantages: ...
