A replaceable glass mold bulkhead

Abstract

The invention discloses a replaceable glass mold bulkhead which comprises a fixed base and a bulkhead core body, wherein the bulkhead core body is arranged at the lower part of the fixed base; a cavity is formed in the middle of the fixed base; the cavity includes a bolt mounting hole extending downwards from the top of the fixed base and a core body matching hole extending upwards from the bottom of the fixed base; two threaded holes are formed in the upper surface of a cylinder; two bolts corresponding to the threaded holes are arranged inside the bolt mounting hole; the bolts penetrate through a kidney-shaped hole and fix the cylinder in the core body matching hole. According to the replaceable glass mold bulkhead provided by the invention, the fixed base is made of cast iron, so that the cost and processing difficulty are low; the bulkhead core body adopts nickel alloy or high-temperature resistant stainless steel, so that the glass mold bulkhead is high in strength and good in durability; in addition, the bulkhead core body can be separated from the fixed base and replaced, so that the production cost is reduced.

Description

technical field [0001] The invention relates to the field of glass mold engineering, in particular to a replaceable glass mold bulkhead. Background technique [0002] Glass molds are professional molds for the production of glass bottles and glassware. The molten glass material is introduced into the mold, and glass products of various shapes are formed through the inner cavity of the mold. Therefore, the shape of the glass mold directly determines the appearance of the glass product. [0003] In the process of production, the glass bottle needs to go through the initial mold and film forming in order to gradually form. In order to work better for the initial mold, a bulkhead is usually set on the opening of the initial mold. The temperature of the glass frit is very high, so the ambient temperature of the bulkhead is very high, and it must be continuously matched with the initial mold, which requires high strength and high temperature resistance of the material. Ordinary b...

AI Technical Summary

Problems solved by technology

Ordinary bulkhead material is cast iron, and its service life is very short. In order to improve the service life, nickel alloy material is usually spray-welded on the working end of cast iron bulkhead or the production of bulkhead is made of integral stainless steel material, which is costly and difficult to process.
