Abstract

The invention relates to a double-cavity controllable pressure high temperature and cold and heat forming system and technique. The heat forming system comprises a high temperature cavity, a low temperature cavity communicated with the high temperature cavity, and a material delivery rod which is arranged in the low temperature cavity in a horizontal mode and is far away from one side of the high temperature cavity, wherein the high temperature cavity comprises an airtight metal shell, an insulating layer, a heating electrode and a loading tray placing device, the insulating layer is arranged inside the airtight metal shell, the heating electrode and the loading tray placing device are arranged on the airtight metal shell, the airtight metal shell is further provided with a high temperature deflation valve and a high temperature air exhaust valve, and a thermal insulating baffle is arranged on a portion, close to the low temperature cavity, inside the high temperature cavity; the low temperature cavity is enclosed by a low temperature airtight metal shell, the inner part of the low temperature cavity comprises a cooling cavity, a material changing cavity and a material changing window, and the low temperature airtight metal shell is further provided with a low temperature air filler valve and a low temperature air exhaust valve; the material delivery rod can penetrate through the low temperature cavity and reach the inner part of the high temperature cavity; the high temperature air exhaust valve is communicated with the low temperature air exhaust valve.

Description

technical field [0001] The invention relates to a thermoforming system and process, in particular to a double-chamber controllable pressure high-temperature quenching thermoforming system and process. Background technique [0002] Glass is a special solid substance with no fixed melting point and isotropic. It is widely used in construction, daily use, medical treatment, chemistry, electronics, instrumentation, nuclear engineering and other fields. The moment the glass material enters the forming mold or forming device, it has both the properties of a complete solid shape and some amorphous properties of molten viscous flow (mainly during processing), and it is in a fixed or amorphous state macroscopically. Shaped and semi-shaped glass is formed by forming a mold from a fixed state and a semi-shaped state to a fixed state under certain process parameters (such as temperature and pressure). In the glass industry, the process of deforming glass products in a shaped state and ...

AI Technical Summary

Problems solved by technology

However, during the forming process, the analysis of glass forming becomes very difficult due to the temperature and viscosity changes of the glass, as well as complex geometric dimensions, etc.

[0004] In traditional thermoforming equipment, limited by equipment conditions, it is impossible to accurately control process parameters (temperature, air pressure, ambient atmosphere, etc.), and carry out continuous mass production of small and micro devices

And the conventional cooling process may produce crystallization, which will deteriorate the forming effect
