Bottom die turnover device of bottle blowing machine

Abstract

The invention discloses a bottom die turnover device of a bottle blowing machine. The bottom die turnover device comprises a die rack bracket, a bottom die bracket, a swing arm capable of being rotatably connected to the die rack bracket around an axis of a first shaft, a bottom die oscillating bar capable of being rotatably connected to the bottom die bracket around an axis of a second shaft, spatial connecting rods, two ends of which are hinged to one ends of the swing arm and the bottom die oscillating bar through a knuckle bearing spherical surface fixedly connected thereto, and a bottom die fixedly connected to the other end of the bottom die oscillating bar. The second shaft is arranged between two ends of the bottom die oscillating bar. During die opening, the swing arm is used fordriving the bottom die oscillating bar to make the other end of the bottom die oscillating bar to overturn toward the side of a bottle picking manipulator around the axis direction of the second shaft. According to the bottom die turnover device of the bottle blowing machine, the bottom die can be matched with the bottle picking manipulator to be stripped synchronously while overturning. In a samedie opening process, the bottom die is relatively small in stroke, is relatively small in acceleration of motion, is relatively small in vibration and impact and is relatively high in stability and reliability of motion.

Description

technical field [0001] The invention relates to the technical field of bottle blowing, in particular to an overturning device for a bottom mold of a bottle blowing machine. Background technique [0002] The blow molding machine is the key equipment for producing various liquid packaging containers. The blow molding machine has strict requirements for each process and high requirements for mutual cooperation, and the process of separating the bottom of the container from the bottom mold is very strict. [0003] In the bottle taking process of the traditional mechanism blow molding machine, after the opening and closing molds are opened at a certain angle, the bottom mold drops to the bottom of the container and is completely disengaged from the bottom mold, and then the bottle taking robot takes out the container. In the traditional mechanism, in order to ensure the time of taking the bottle, the time from the beginning of the bottom mold to the complete separation from the c...

AI Technical Summary

Problems solved by technology

In the traditional mechanism, in order to ensure the time of taking the bottle, the time from the beginning of the bottom mold to the complete separation from the container is short, the acceleration of the bottom mold is relatively large, the stroke of the bottom mold is large, and the vibration and impact are relatively large. The stability and reliability of the movement are poor
