A mold for making glassware

Abstract

The invention discloses a mould for manufacturing glassware, and relates to the technical field of glassware. The mould comprises cavity mould casings which are matched symmetrically and a base; the cavity mould casings are of semicircular structures; a plurality of fixed guide posts are uniformly arranged on the outer surfaces of the cavity mould casings side by side; the fixed guide posts are fixed to bypass seats through radiating frames; one end of each of the cavity mould casings which are matched symmetrically is matched with the base. According to the mould, the glassware is formed by adopting the oppositely opening type cavity mould casings; the glassware is formed by taking the cavity mould casings as a thin casing; the forming speed is high; the stress damage to the structure ofthe glassware is avoided by adopting an oppositely opening structural form; temperature compensating and heat conducting properties of the mould are improved by the radiating frame structures on the outer surfaces of the cavity mould casings; the surrounding ambient temperature can be risen quickly through heat transfer by convection because of a cylindrical structure.

Description

technical field [0001] The invention belongs to the technical field of glass moulds, in particular to a mold for making glassware. Background technique [0002] The aforementioned glassware such as various glass pot lids, cup lids, various glass basins with reinforcing ribs, and the like. As known in the industry, the process of making glassware is not limited to the process of making glass containers, such as various wine bottles, glass cups, cosmetic bottles, sauce jars, vases and beverage bottles, etc. Wait. In the process of manufacturing such glassware and glass containers, the glass frit must be introduced into the glass mold first, and then blown, pressed or centrifugally formed according to different processes, and the mold should be made as fast as possible during the forming process. Otherwise, the gas trapped in the mold cavity will enter the glassware or glass container, resulting in visible bubbles in the glass product, which will affect the appearance quality...

Problems solved by technology

In the process of manufacturing such glassware and glass containers, the glass frit must be introduced into the glass mold first, and then blown, pressed or centrifugally formed according to different processes, and the mold should be made as fast as possible during the forming process. The gas in the cavity is discharged, otherwise the gas trapped in the cavity will enter the glassware or glass container, resulting in visible bubbles in the glass product, affecting the appearance quality, and even affecting the molding

[0003] Most of the molds used for glassware in the prior art are of a rotating structure, and the two half molds are hinged on one side to form a rotating split structure, and the mold structure is thick and heavy, which is easy to increase the generation of air bubbles
