Technology of injection moulding with surface of glass bottle body fully coated with plastic and mould thereof

Abstract

The invention discloses a technology of injection moulding with the surface of a glass bottle body fully coated with plastic. The technology comprises the following steps: preparing a mould and an injection molding machine matched with the mould, and preparing a plastic raw material and a glass bottle; placing the glass bottle between the front mould insert and the rear mould insert of the mould, and fixing the glass bottle with a plastic sleeve; and setting the technological parameters of injection moulding of the injection molding machine after mould assembly, and performing edge-gate plastic injection upwards from the bottom of the glass bottle to finish injection moulding. The invention further discloses the mould used in the technology of injection moulding. According to the invention, full plastic coating of the surface of the glass bottle body is realized through once injection moulding, the glass bottle body is prevented from explosion in the production process, the product quality is guaranteed, the percentage of breakage of the glass bottle body is almost zero, the production safety is greatly guaranteed, the production efficiency is improved, the finished product has high quality and a good appearance, the surface of the product feels good and soft, and the product has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of glass bottle overcoating injection molding, in particular to a molding process and a mold for a glass bottle body surface fully covered with plastic. Background technique [0002] At present, the vast majority of cosmetic perfume bottles on the market use glass bottles, but there is no perfume bottle body in the market that is fully covered with rubber materials on the surface of glass bottles. The rubber material is injected into the periphery of the base material of the bottle body to form a complete part. In order to complete this process, it can be completed by multiple injection molding and insert injection molding. The covering material usually used is elastic rubber, and the multiple injection molding is in the structure of the covering material. When allowed, a special injection molding machine equipped with multiple barrels is usually required to inject different objects into an injection mold. T...

Problems solved by technology

[0003] However, using the aforementioned existing methods, in order to produce such products as fully-covered injection-molded glass bottles, it is necessary to use embedded glass. In order to achieve complete coverage, multiple injection molding, secondary injection molding or co-glass bottle interlayer injection molding must be used. Put the glass bottle on the copper sleeve first, and then close the mold for beer molding, but there are problems such as the glass bottle is fragile, it is difficult to achieve full coating, and the product quality cannot be guaranteed.
