Method for producing colored glass bottle by centrifugal casting

Abstract

The invention discloses a method for producing colored glass bottle by centrifugal casting, and belongs to the the technical field of colored glass bottle production. The method comprises the following steps that a glass liquid is dropped in a forming chamber; a plunger chip is pressed down to form a billet; a bottom die and a ring die are rotated at a high speed, and cooling water is introduced into a cooling passage through a water inlet; a conical head is rotated to feed water containing pigments into a water inlet hole; the plunger chip is rotated so that the water in the water inlet hole is sprayed to the glass liquid, as the bottom die rotates at a high speed, the water containing pigments will be uniformly distributed in the interior of the glass liquid until the formation of a colored glass bottle under the influence of centrifugal force and the flowing glass liquid. Compared with traditional way of producing colored glass bottle by changing raw material of the glass liquid, the method is more convenient by adding different pigments to the water according to production demands, and thus colored glass bottles with different color are obtained, which are free from limitations of the raw materials.

Description

technical field [0001] The invention relates to a forming method of a glass bottle. Background technique [0002] The centrifugal casting method is a common method for forming large glass products. The centrifugal casting method is to install a ring mold on the bottom mold, inject the glass liquid into the bottom mold, first use the punch to hydraulically form the glass body, and then make the bottom mold rotate at high speed , The molten glass flows along the peripheral wall of the bottom mold under the action of centrifugal force and expands to form. [0003] At present, the glass products produced by centrifugal casting method on the market often have a single color, while the production of some colored glass mainly relies on the improvement of raw materials. Through the improvement of raw materials, the glass products produced have a certain color. The way to achieve the change of glass color is greatly affected by the characteristics of the raw material itself, which c...

Through the improvement of raw materials, the glass products produced have a certain color. The way to achieve the change of glass color is greatly affected by the characteristics of the raw material itself, which cannot fully meet the needs of production
