Description

Forming station

[ technical field ] A method for producing a semiconductor device

The utility model relates to a glass processing technology field especially relates to a shaping worker station.

[ background of the invention ]

The existing glass mold is hot-pressed and formed by an upper mold and a lower mold. Because the glass forming temperature is higher and the glass product forming time is longer, the existing hot bending machine is generally divided into a plurality of work stations for continuous processing. The general working process of the hot bending machine is as follows:

1. and a heating station, wherein heating rods are arranged in the upper and lower shaping plates of the heating station to heat the mould, so that the temperature of the mould and the glass gradually rises from room temperature to the softening temperature of the glass.

2. And a pressurizing station, wherein when the temperature of the mold and the glass reaches the temperature capable of hot bending, a pressure rod of the hot bending machine moves downwards to drive the upper shaping plate to move downwards so as to close the upper mold and the lower mold.

3. And a cooling station, wherein water cooling devices are arranged on an upper shaping plate and a lower shaping plate of the cooling station to cool the mold, so that the temperature of the mold and the glass is gradually reduced from the softening temperature of the glass to the room temperature.

When the existing hot bending machine is used for producing glass products, the die is only pressed downwards by a single force application device in the whole process. In the cooling station, the mold is in a clamped state. Therefore, the mold cannot be opened during cooling, and the glass article is always in close contact with the molding surface of the mold after molding.

After the glass is formed at a high temperature, the size and the curved surface shape of the glass are changed along with the change of the temperature. If the distance between the upper die and the lower die and the bonding force between the glass and the die cannot be adjusted according to the temperature change, the glass can wrap the die (male die/female die) to generate tensile stress or compressive stress during the cooling process, so that microcracks and even cracks exist in the glass product. Therefore, the common hot bending machine is easy to cause the glass product to break and deform in a cooling station, the production efficiency of the product is reduced, and the production cost is increased.

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