Glass forming furnace

Abstract

A glass forming furnace includes a furnace body, a conveying channel, a pushing rod device, at least one first heater, at least one second heater, and a cooling device; the furnace body includes a loading region, a forming region, a cooling region, and an unloading region; the conveying channel is used for holding a plurality of forming lower dies; the pushing rod device is arranged on one end of the conveying channel ,uses one pushing rod to push the forming lower dies, and allows the forming lower dies to successively pass through the loading region, the forming region, the cooling region, and the unloading region; the first heaters are arranged above the conveying channel; the second heater are arranged below the conveying channel; and the cooling device is used for injecting cool gas into the cooling region, allowing the cool gas to successively pass through the cooling region, the forming region and the loading region, and the cool gas leaves the furnace body from the loading region.

Description

technical field [0001] The invention relates to a glass forming furnace, in particular to a glass forming furnace which can provide three heating modes and is suitable for various forming processes. Background technique [0002] With the advancement of technology, many electronic devices gradually adopt touch devices to replace traditional mechanical operating devices, and increase the size of the operating space and display to provide more intuitive and convenient operation methods, such as the central control screen of smart phones or cars and other devices. Under such a background, the demand for touch devices in different fields is greatly increased, and the glass on the touch devices also needs different shapes to match different devices. [0003] At present, the shape of glass is made by placing flat glass raw material on a mold and heating the mold to soften the glass raw material. Then, through negative pressure or molding, the glass raw material is bonded to the m...

AI Technical Summary

Problems solved by technology

If the glass cannot be heated evenly, unexpected errors will occur in the glass during the molding process, resulting in reduced production efficiency, lower yield, and lowered overall Process Capability Index (CPK, Process Capability Index)

[0005] However, in the currently commonly used glass forming process, most of the forming furnaces cannot heat the glass evenly. Therefore, how to make the glass evenly heated during forming and improve the production efficiency is worth considering for those with ordinary knowledge in the field.
