Problems solved by technology

[0003] With the continuous development of the speed of glass bottle making machines and the continuous introduction of lightweight bottles, the small-mouth pressure blowing process has further special requirements for mold materials. The traditional vanadium-titanium-molybdenum cast iron glass molds seem to be unable to do what they want. For example: The abrasiveness cannot keep up with the requirements, the hardness is not enough, and sometimes it is easy to appear "pockmarks" during use, which leads to the premature end of the mold life, and must have good oxidation resistance and high temperature fatigue strength at high machine speeds

Abstract

The invention discloses a glass mould material and a preparation method thereof. The glass mould material comprises the following components in part by weight: 30-50 parts of graphite, 0.6-0.88 part of copper, 3-5 parts of silicon, 10-15 parts of tungsten powder, 0.5-0.98 part of titanium, 0.012-0.335 part of molybdenum and 30-35 part of iron powder. The invention further discloses a preparation method of the glass mould material. The glass mould material benefits as follows: the glass mould material is scientific and reasonable in component matching; through addition of titanium and copper, the wear resistance and the hardness are greatly improved; the glass mould material is more stable in performance; the service life of the glass mould material is prolonged; the preparation method is simple in process and the components are easy to obtain, so that the manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to a mold material, in particular to a glass mold material, and also to a preparation method of the glass mold material. Background technique [0002] Glass molds are equipment used to manufacture glass containers. The molding of glass products and the quality of the molding of glass products depend on the quality of the mold. [0003] With the continuous development of the speed of glass bottle making machines and the continuous introduction of lightweight bottles, the small-mouth pressure blowing process has further special requirements for mold materials. The traditional vanadium-titanium-molybdenum cast iron glass molds seem to be unable to do what they want. For example: The abrasiveness cannot meet the requirements, the hardness is not enough, and sometimes "pockmarks" are prone to appear during use, causing the mold to reach the life ahead of time, and it must have good oxidation resistance and high temperature fatigue stre...
