Hanging ring integrated infusion bottle forming process

Abstract

The invention discloses a hanging ring integrated infusion bottle forming process. The process comprises the following steps of bottle blank forming injection molding, blank body forming, pouring gate column forming, hanging ring forming injection molding and infusion bottle blow molding, specifically, an obtained bottle blank of a hanging ring integrated infusion bottle is subjected to blow molding through a blow molding machine to form the hanging ring integrated infusion bottle. Forming and connecting of the bottle blank and a hanging ring are achieved through two times of injection molding, a plug does not need to be welded, then workshop environment pollution caused when the plug is welded is avoided, the risk of bottle body pollution is eradicated, and the product quality is guaranteed. Meanwhile, the problems of high positioning precision requirements of a bottle blank mold and a hanging ring mold, difficulty in demolding, large injection molding pressure and mold clamping force and the like existing in one-time injection molding of the bottle blank and the hanging ring are solved.

Description

technical field [0001] The invention relates to the technical field of preform production, in particular to a molding process for an infusion bottle with integrated suspension rings. Background technique [0002] Infusion is to inject large doses of injection into the human body through intravenous drip. At present, the plastic infusion bottle has gradually replaced the traditional glass infusion bottle, and the bottom of the plastic infusion bottle needs a suspension ring, which is convenient to hang on the fixed hook when in use. Generally, the bottom of the plastic infusion bottle is provided with a suspension ring structure, so that it is no longer necessary to use other auxiliary structures (such as a net bag, a fixing frame, etc.) for hanging. [0003] The suspension ring of the existing preform adopts 1. The suspension ring and the preform are formed separately, and then the forming suspension ring is welded to the gate column of the formed preform; 2. The suspension...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a ring-integrated infusion bottle molding process, which realizes the forming and connection of the preform and the ring through two injection moldings, and does not need to weld the plug, thereby avoiding the need for welding the plug. The environmental pollution of the workshop caused by it will eliminate the risk of polluting the bottle body and ensure the quality of the product; at the same time, avoid the high positioning accuracy of the preform mold and the hanging ring mold in the one-time injection molding of the preform and the hanging ring, difficult demoulding, injection pressure and clamping force major issues
