Mold for countersink formation in joint close position of glass bottle opening

Abstract

The invention provides a mold for countersink formation in the joint close position of a glass bottle opening. The mold comprises a mouth mold and a pair of countersink formation pieces, wherein eachcountersink formation piece comprises V-shaped sliders and cores for forming a countersink, the boundary dimension of the tail end of each core is adapted to the countersink, and the tail end of eachcore serves as a countersink formation end; the mouth mold is formed by two half mouth molds, a central cavity serves as a cavity, an interface of the two half mouth molds serves as a joint surface, apair of V-shaped sliding chutes and a pair of core holes which are distributed symmetrically are formed in the outer side corresponding to a pair of countersink formation positions, are adapted to the countersink formation pieces and serve as core moving guide slots; the V-shaped sliders of the mold are glidingly arranged in the V-shaped sliding chutes, the cores are put in the core holes, and the pair of countersink formation pieces can move in the same direction or in the opposite directions along the corresponding core moving guide slots with closing or separation of the two half mouth molds. The mold is ingenious in structure design and easy to process, and the technical problem that countersink formation in the joint close position of the glass bottle opening cannot be realized in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of daily-use glass bottle mold manufacturing, more specifically to a mold for counterbore forming at the seam line of the glass bottle mouth. Background technique [0002] figure 1 Shown is a metal ring cork (commonly known as a swing cap) with a self-tightening function. Figure 2a and Figure 2b The necks of the two glass bottles shown are compatible with figure 1 The metal ring stopper shown is matched, and after assembly, the stopper 1a' of the metal ring stopper is sealed on the bottle mouth of the glass bottle, and the pair of hooks 1c' on both sides of the metal ring 1b' correspond to each other. Embedded in a pair of sink holes on both sides of the side wall of the bottle mouth to form a fit, such as Figure 3a and Figure 3b shown. The difference between these two glass bottles is: Figure 2a The shown counterbore 2a' is located on the seam line on the side of the bottle mouth; Figure 2b Th...
