Glass bottle mould

Abstract

The invention discloses a glass bottle mould, and relates to the technical field of moulds. The glass bottle mould comprises a forming mould, a mouth mould, a bottom mould and a blow head, wherein the forming mould is made from a cast iron material, a first blocking groove is formed in the forming mould, and a first excitation coil is arranged in the first blocking groove; a forming cavity is formed between the forming mould and the bottom mould; a plurality of steel balls are arranged in the forming cavity; the glass bottle mould also comprises a ball suction iron rod; a second blocking groove is formed in the ball suction iron rod, a second excitation coil is arranged in the second blocking groove, the ball suction iron rod can extend into the forming cavity, a vent hole is formed in the ball suction iron rod, and a plurality of exhaust holes communicated with the vent hole are also formed in the part, extending into the forming cavity, of the ball suction iron rod. When the glass bottle mould adopting the scheme is used for producing glass bottles, the heat in the glass bottles also can be effectively dissipated in time, so that the problem that the glass bottles have cracks or are broken since stress, caused by not timely cooling of the interiors of the glass bottles during glass bottle production, is easily generated in the glass bottles can be avoided.

Description

technical field [0001] The invention relates to a mold. Background technique [0002] The forming of glass bottles is the process of transforming molten glass into products with fixed geometric shapes. Forming is an important process in the production of glass bottles, and it also has a great impact on the output, quality and economic benefits of glass bottles. Glass Bottle forming methods mainly include pressure blowing method and calendering method. [0003] The characteristic of the pressure-blow method is that the mouth and prototype of the product are made by pressing first, and then moved into the forming mold to blow the product. The pressure-blow method needs to use a mold when blowing the molten glass into a product. The mold generally includes The forming mold, the bottom mold, the mouth mold and the blowing head, through the compressed air into the blowing head, the glass liquid flows under the action of the compressed air and finally forms a glass product. When ...
