Problems solved by technology

[0002] Most of the clamping oil cylinders of the existing clamping mechanism are of external structure, which makes the structural size of the entire clamping mechanism larger, and the mold opening stroke of the existing clamping mechanism is relatively short, which is not suitable for injection molding of deep cavity preforms The processing of parts (such as five-gallon preforms) leads to high processing costs and poor quality of such deep-cavity preform injection molded parts

Abstract

The invention discloses a new five-gallon preform mold clamping mechanism, which includes a frame, a rear template, a fixed template, a movable template, tie rods, and a mold clamping oil cylinder. The rear template and the fixed template are arranged at intervals and fixed on the frame, and the tie rods are connected. The rear template and the fixed template, the movable template is set between the rear template and the fixed template, and can do reciprocating linear movement on the tie rod, the mold clamping cylinder can be moved between the rear template and the movable template through the connecting component, and the mold clamping cylinder The end of the piston rod is fixedly connected with the movable template. The new five-gallon preform mold clamping mechanism of the present invention moves the mold clamping cylinder between the rear platen and the movable platen through the connecting assembly. On the one hand, the mold clamping cylinder is built in, which greatly reduces the entire mold clamping mechanism. On the other hand, the mold clamping cylinder of the mobile structure greatly increases the mold opening stroke of the entire mold clamping mechanism, which can reach more than 1.7 times the stroke of the piston rod of the mold clamping cylinder.

Description

technical field [0001] The invention relates to a mold clamping mechanism of an injection molding machine, in particular to a novel five-gallon bottle blank mold clamping mechanism. Background technique [0002] Most of the clamping oil cylinders of the existing clamping mechanism are of external structure, which makes the structural size of the entire clamping mechanism larger, and the mold opening stroke of the existing clamping mechanism is relatively short, which is not suitable for injection molding of deep cavity preforms The processing of parts (such as five-gallon preforms) leads to high processing costs and poor quality of such deep-cavity preform injection molded parts. Contents of the invention [0003] The purpose of the present invention is to provide a novel five-gallon preform clamping mechanism, which has simple structure, small size and long mold opening stroke, and is suitable for processing deep-cavity preform injection molded parts. [0004] For reachi...
