Method for producing a headlight lens for a vehicle headlight

A method of producing a headlight lens for a vehicle headlight, the method comprising:

• providing a heated blank of glass;
• providing a first partial mold;
• providing a second partial mold;
• providing at least a third partial mold;
• providing a ram;
• press-molding the heated blank between the first partial mold, the second mold, and the third partial mold to form a headlight lens having an integral body made of glass, the integral body comprising at least one light tunnel and a light-passage section having at least one optically active light exit surface, wherein the light tunnel comprises at least one light entry surface and, with a bend, transitions into the light-passage section configured to image the bend as a bright-dark-boundary by means of light directed into the light entry surface, wherein the press-molding comprises:
• molding at least a portion of the light tunnel by means of the second partial mold;
• and
• molding at least a portion of the light-passage section by means of the first partial mold and the third partial mold.

• providing a heated blank of glass;
• providing a first partial mold;
• providing a second partial mold;
• providing at least a third partial mold;
• providing a ram;
• providing an actuator, a mold and the actuator being connected by means of a first movable guide rod and at least a second movable guide rod, wherein the first movable guide rod is guided in a recess in a fixed guide element and the second movable guide rod is guided in a recess in the fixed guide element, the mold being one of the group consisting of the first partial mold;
• the second partial mold;
• and the third partial mold;
• press-molding the heated blank between the first partial mold, the second mold, the third partial mold to form a headlight lens having an integral body made of glass, the integral body comprising at least one light tunnel and a light-passage section having at least one optically active light exit surface, wherein the light tunnel comprises at least one light entry surface and, with a bend, transitions into the light-passage section configured to image the bend as a bright-dark-boundary by means of light directed into the light entry surface.

• providing a heated blank of glass;
• providing a first partial mold;
• providing a second partial mold;
• providing at least a third partial mold;
• providing a ram;
• providing an actuator;
• providing a frame, which comprises a first fixed guide rod and at least a second fixed guide rod, wherein the first fixed guide rod and the at least second fixed guide rod are connected at one end by an actuator-side fixed connector and at the other end by a mold-side fixed connector, wherein a mold is fixed to a movable guide element, which comprises a first recess through which the first fixed guide rod is guided and a second recess through which the at least second fixed guide rod is guided, the mold being one of the group consisting of the second partial mold and the third partial mold;
• moving the second partial mold and the third partial mold towards each other;
• and
• press-molding the heated blank between the first partial mold, the second mold, the third partial mold to form a headlight lens having an integral body made of glass, the integral body comprising at least one light tunnel and a light-passage section having at least one optically active light exit surface, wherein the light tunnel comprises at least one light entry surface and, with a bend, transitions into the light-passage section configured to image the bend as a bright-dark-boundary by means of light directed into the light entry surface.
