Description

Forming station

Technical field

The utility model relates to the technical field of glass processing, in particular to a forming station.

Background technique

The existing glass molds are formed by hot pressing of upper and lower molds. Because the glass forming temperature is relatively high and the glass product forming time is relatively long, the existing hot bending machine is generally divided into multiple work stations for continuous processing. The general working process of the hot bending machine is:

1. In the heating station, heating rods are installed in the upper and lower mold plates of the heating station to heat the mold, so that the temperature of the mold and glass gradually rises from room temperature to the glass softening temperature.

2. Pressing station. In the pressurizing station, the mold and glass have reached the temperature that can be bent. The pressing rod of the bending machine moves downwards, which drives the upper plate to move downwards to close the upper and lower molds.

3. In the cooling station, water cooling devices are installed on the upper and lower mold plates of the cooling station to cool the mold, so that the temperature of the mold and glass gradually decreases from the glass softening temperature to room temperature.

technical problem

When the existing hot bending machine produces glass products, the mold will only be subjected to a single downward pressing force of the force applying device during the entire process. In the cooling station, the mold is in a closed state. Therefore, the mold cannot be opened during the cooling process, and the glass product has been in close contact with the molding surface of the mold after molding.

If the distance between the upper and lower molds and the bonding force between the glass and the mold cannot be adjusted according to the temperature change, during the cooling process, the glass may wrap the mold (punch/concave mold) to generate tensile or compressive stress, resulting in glass products There are micro-cracks or even cracks inside. Therefore, the ordinary hot bending machine can easily cause the glass product to break and deform in the cooling station, reduce the production efficiency of the product, and increase the production cost.

Therefore, it is necessary to provide a new molding station to solve the above technical problems.
