る。(Problems to be solved by the invention) In recent years, the shape of automotive headlight lenses has become larger.
Since there is a tendency for the front part 16 and the side part 1 of the lens glass to be fabricated, as shown in FIG.
7 is now required to have a narrow angle a of 90 degrees or less. With this shape, when the bottom surface of the bottom mold is made horizontal using a conventional press molding machine, the mold extraction slope Θ p and the product draft angle Θ B are opposite to the extraction direction, so the vertical It is not possible to mold with a press die that moves up and down. In order to mold such a shape, the bottom mold 2' may be installed at an angle so as to obtain a normal draft angle in the vertical direction, as shown in FIG. The glass gob G supplied to the bottom mold 2' moves to one side of the bottom mold 2' before it is pressed, and in this state, the pressing mold 3' is inserted into the bottom mold 2' and the glass gob G is press-molded. is extremely difficult.

ようになつている。 In FIG. 1, eight bottom molds 2 are installed at equal intervals along the circumference on the upper surface of a disc-shaped base 1 that rotates intermittently. As shown in the figure, the bottom surface of the bottom mold 2 is substantially horizontal, and the mold cutting direction is directed diagonally upward. A press die 3 that engages with the bottom die 2 is attached to a support plate 4. Support plate 4 is drive rod 5
It is connected to the pressing cylinder 6 via a guide shaft 7 which is provided in parallel to the direction in which the bottom die 2 is cut out, and is attached to the guide shaft 7 so as to be movable up and down. By sliding the support plate 4 along this guide shaft 7, the press die 3 is made to reciprocate diagonally in accordance with the die cutting direction of the bottom die 2.

As shown in FIG. 2, when the glass gob G is supplied to the bottom die 2 and the press cylinder 6 is activated, the support plate 4 is lowered obliquely along the guide shaft 7, and the press die 3 attached to the support plate 4 is The product 8 is inserted into the bottom mold 2 and pressed against the glass gob G to form the product 8. After press molding, the press die 3 is separated obliquely upward from the bottom die 2, and the product 8 is taken out to the outside through a cooling process. In this press molding apparatus, the bottom surface of the bottom mold is held horizontally, so the supplied glass gob does not move from a predetermined position, is stable, and can be press molded easily. In addition, this press molding process is similar to that of a conventional press molding device, as shown in Fig. 3, and P 1
Molded products are continuously produced by feeding the glass gob into the bottom mold at step P2, press-molding it into a predetermined shape at step P2 , passing through the cooling process from step P3 onwards, and taking the product out to the outside at step P6 .
