Glass tube molding mold, device and method

Abstract

The invention discloses a glass tube molding mold, device and method. The mold is installed at a discharge port of a molten glass material supply device and comprises an inner mold body, and the inner mold body is installed at the discharge port of the material supply device and comprises a connecting rod and a molding part; the molding part comprises a molding surface, the molding surface is the surface, facing the discharge port, of the molding part and is a spherical surface or conical surface or curved surface which protrudes towards the connecting rod, and at least one material groove is formed in the molding surface in a concaved mode and extends to the bottom of the molding surface from the corresponding joints. In the manufacturing technology, molten glass flows to the molding surface of the inner mold body through flow channel clearances formed in the discharge port, the molding surface guides the molten glass to be diffused in a curved surface mode to form a tube in the initial stage that the molten glass is converted from the flow state to the solidified state, inner ribs are formed by the molten glass flowing along the material grooves on the inner side of the tube, and then the glass tube is driven by a traction device to rotate, so that the inner ribs are in a spiral shape. Accordingly, the production problems in the prior art are solved, and the glass tube with the spiral ribs on the inner wall is produced.

Description

technical field [0001] The present invention generally relates to a glass processing device, in particular to a glass tube forming mold capable of producing shaped inner walls, a glass tube forming device and a forming method. Background technique [0002] The general production process of glass tubes in the prior art is as follows: the batch materials are mixed evenly and sent into the electric melting furnace, the melted glass enters the ascending channel and the forehearth through the liquid hole, and the glass liquid overflows in the forehearth Excrete the surface waste, supply the homogenized glass liquid that meets the molding temperature to the feeder, and then enter the vacuum runway, heat preservation runway, laser detection, and tube drawing machine through the homogenizing barrel, blowing rod, material bowl, and end. , and then the qualified glass tubes are sorted by a sorting machine and a carding machine, and finally packed by hand before being transported into ...

AI Technical Summary

Problems solved by technology

[0013] In view of the difficulty in processing glass tubes with internal shapes in the traditional glass tube processing technology, the main purpose of the present invention is to provide a glass tube forming mold capable of producing internally shaped glass tubes, a glass tube forming device and a forming method
