Mould for processing glass container

Abstract

The invention provides a mold for processing a glass container and belongs to the technical field of mold. The mold includes a pair of half molds that are opposite to each other and a pair of bottom molds at the bottom of the half molds, a mold cavity is respectively opened along the height direction at the middle of each side of the opposing sides of the two half molds. The mold is characterized in that a vacuum groove is respectively opened at each side along the height direction of the mold cavity, and ventholes which are equal in number with the vacuum grooves and are communicated with the vacuum grooves are opened at the side edge of the bottom mold core, also a central hole for connecting with the vacuum pipeline is opened at the center of the bottom mold core and the central hole is communicated with the venthole. The mold has the advantages that the pair of half molds can have ideal closing effect due to the vacuum grooves at each side of the mold cavity, which restricts the deformation of the half molds, and guarantees that the glass container is smooth and has good quality.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a mold for processing glass containers. Background technique [0002] As is well known in the industry, molds for glass containers are used at high temperatures, so the problem of mold deformation has always troubled the industry, because molds for processing glass containers are composed of a pair of half molds, and the combination of a pair of half molds The seam surface can be said to be satisfactory at the beginning without gaps. However, due to the influence of high temperature factors after being put into use, the pair of mold halves deformed, and the gap between the seam surfaces became larger, resulting in obvious gaps on products such as bottles. The ribs will affect the appearance quality of the bottle, and in severe cases, the bottle will be scrapped unless a new mold is replaced. Contents of the invention [0003] The task of the present invention is to provide a mo...
