Bottle blowing machine bed die locking mechanism

Abstract

A bottle blowing machine bed die locking mechanism comprises a baseboard and a bed die rivet provided with positioning grooves, the baseboard is provided with a turning block and locking blocks, and the turning block drives the locking blocks to be clamped in the positioning grooves in order to lock the bed die rivet. The bottle blowing machine bed die locking mechanism realizes locking through the cooperative fixation of the locking blocks and the bed die rivet, so the mechanism has a very simple structure; components are large and solid blocky structures have a good wear resistance and service durability, difficulty cause the loss, so it is in favor of prolonging the service life and reducing the cost; and the arrangement of the components on the baseboard not in the mechanism is convenient to maintain and replace the components, so the maintainability is improved, and the maintenance difficulty is reduced, thereby it is in favor of the normal use of a bottle blowing machine.

Description

technical field [0001] The invention relates to a locking mechanism of a blow molding machine, in particular to a bottom mold locking mechanism of a blow molding machine. Background technique [0002] The bottle blowing machine is the equipment in the field of plastic bottle processing and manufacturing such as beverage bottles, oil bottles, and medicine bottles. The bottle blowing machine includes a left mold, a right mold and a bottom mold, and the three cooperate to form a complete bottle cavity. When working, open the left, right and bottom molds and place the preform in the cavity, then close the left and right molds and the bottom mold to blow the preform, and open the left and right after the bottle is formed. The right mold and the bottom mold, at this time the bottom mold descends and exits the position of the cavity, and the bottle body after processing is taken away and sent to the next process. After the bottom mold exits the cavity, it needs to be locked and ...

AI Technical Summary

Problems solved by technology

The bottle blowing machine will vibrate during the whole working process, and the locking mechanism of the bottom mold will vibrate accordingly, which will cause strong extrusion and friction between the steel ball and the inner groove of the piston, resulting in damage or rupture of the steel ball and concave inner piston. The wear of the groove reduces the locking effect of the locking mechanism or even fails, and the replacement operation of the steel ball and the piston is complicated and difficult, which greatly affects the use of the blow molding machine
