Silica glass compression molding apparatus and method

A silica glass compression molding apparatus, comprising:

• a mold, a stamping component, a heating component, a cooling component and a braking component,
• wherein the mold comprises a first mold and a second mold with molding surfaces, the first mold and the second mold are arranged opposite to each other, and the first mold is disposed above the second mold;
• the stamping component comprises a pressing unit for stamping the first mold;
• the heating component comprises a heating chamber, an electromagnetic heating unit and an infrared heating unit, wherein the electromagnetic heating unit is wound on the first mold and the second mold, the infrared heating unit is disposed on the heating chamber, and the heating chamber is configured to accommodate the first mold and the second mold within a chamber body under the control of the braking component;
• a supporting base is arranged between the pressing unit and the first mold, and when the first mold and the second mold are accommodated within the heating chamber, the heating chamber is abutted against the supporting base to form a closed environment;
• and
• the cooling component comprises a water cooling unit and an air cooling unit, wherein the water cooling unit is arranged on an outer side wall of the heating chamber, the air cooling unit is arranged on one side of the supporting base away from the first mold, and the air cooling unit delivers cold air into the heating chamber through a via hole provided in the supporting base.
