AI Technical Summary

⚠Technical Problem

The flash removal device of existing blow molding machines is prone to jamming under mold problems, resulting in flash not being removed or flash flying around randomly, and operation depends on the operator's experience.

⚗Method used

It adopts a combination structure of cylinder, mounting plate, chuck, push plate, guide post, guide sleeve, guide rod, hinge shaft and waist-shaped hole. The chuck is V-shaped and the bottom of the push plate is provided with groove and limit clamping piece. The cylinder drives the chuck to clamp the flash and pull the push plate to achieve stable flash removal.

🎯Benefits of technology

It enables stable completion of the edge-attaching action without relying on operational experience, avoiding problems such as edge jamming and random edge flying, and improving the stability and automation of the device.

Abstract

A flash removal device for a blow molding machine, relating to the field of blow molding machine technology, comprises a cylinder, a mounting plate, a cylinder connector, a chuck, a push plate, a guide post, a guide sleeve, a guide rod, a hinge shaft, and a slotted hole. The cylinder is fixed to the mounting plate, and the piston rod end of the cylinder is screwed to the cylinder connector, which has a slotted hole. The end of the chuck is fixed to the guide rod, and the middle part of the guide rod passes through the slotted hole. The middle part of the chuck is connected to the push plate via a hinge shaft, and the push plate is screwed to the guide post. The guide post is slidably connected within the guide sleeve, which is fixed to the mounting plate. This flash removal device for a blow molding machine eliminates the need for operator experience and can complete the flash removal operation even with minor mold defects, solving the problem of flash jamming in existing flash removal technologies.
