Technical Field

The invention belongs to the technical field of manufacturing of flaring cups, and particularly relates to a novel method for manufacturing a flaring thin-wall cup.

Background

The thin-wall cup manufactured by adopting the plastic suction process has the defects that the raw materials are not completely utilized, the vacuum suction is mainly carried out on the plastic suction, the finished product is easy to have the defects of thick one side, thin one side, non-uniform thin back and poor consistency, the waste of leftover materials of the sheet is 30-50 percent in the manufacturing process after the middle is thin and the two ends are thin generally; although the injection molding process is adopted, the finished product is manufactured at one time, but the finished product manufactured by the injection molding process has insufficient toughness, is relatively brittle and is easy to crack.

Therefore, a new thin-wall cup manufacturing process is developed, the advantages of plastic suction and injection molding are achieved, the defects of the two principles are overcome, and the method which has no raw material waste in the thin-wall cup manufacturing process, is good in uniformity and consistency after the wall of the finished cup is thin, good in toughness and high in productivity has important significance.

Disclosure of Invention

The invention aims to provide a method for manufacturing an opening-expanding thin-wall cup, which has the characteristics of low cost, uniform and thin thickness of a finished cup wall and a bottle body, good consistency, good toughness and low possibility of being broken.

In order to achieve the purpose, the invention provides the following technical scheme: a new method for manufacturing a flaring thin-wall cup comprises the following steps of S1, performing injection molding on a bottle blank, and manufacturing the bottle blank by adopting a high-efficiency precision mold and a high-plasticity machine; s2, drawing and blow molding, wherein the bottle blank manufactured in the step S1 is subjected to stretch blow molding by using an efficient bottle blowing machine, and then the bottle blank is blown into a required thin-wall structural shape.

Further, in the step S2, the stretching time of the bottle preform is 0.1S to 0.3S.

Further, the operating temperature in the step S2 is 110-.

Compared with the prior art, the thin-wall cup manufactured by adopting the injection, drawing and blowing processes has the advantages of high productivity, uniform thickness of the finished cup, good consistency and good toughness compared with the traditional process for manufacturing the thin-wall cup. The problems that the middle of a thin-wall cup manufactured by the traditional plastic uptake process is thin, the two sides of the thin-wall cup are thick, sheet materials cannot be well and uniformly utilized, and the hand feeling of the thin-wall cup is not good are solved, and the problems that the thin-wall cup manufactured by the injection molding process is not good in toughness and easy to crack are also solved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
