体7の外周面に近い位置で雌型2に重合する。When the male die 6 descends, the ring die 4 closes the gap between the upper edge of the female die 2 and the outer peripheral surface of the male die 6, and flows out from between the male die 6 and the female die 2 by pressing. The molten glass B is guided to form the opening peripheral edge A1 of the headlamp lens A, and the hollow portion 5 of the ring mold 4 guides this when the male body 7 descends. The introduction portion 5a formed to be slightly larger than the outer diameter and the fitting portion 5 formed to have substantially the same outer diameter as the male main body 7 so as to be in close contact with the outer peripheral surface of the male main body 7.
b, and a molding portion 5c formed by expanding the inner diameter from the fitting portion 5b of a predetermined wall thickness of the opening peripheral edge A1 for guiding the molten glass B and molding the opening peripheral edge A1 of the headlight lens A. It consists of. The ring mold 4 of this embodiment is a female mold 2.
The peripheral edge A1 of the opening is formed to be narrower than the outer peripheral surface A2 of the lens A formed by the molding. Therefore, the molding portion 5c is formed on the male body 7 more than the upper edge of the concave portion 3 of the female die 2. The female mold 2 is polymerized at a position close to the outer peripheral surface.

In this groove portion 22, the projecting and retracting piece 23 is in close contact with the inner surface, and
It is fitted so that it can slide in the penetrating direction. Haunting piece 23
Is provided with a frame base 24 that is thicker than the projecting / retracting frame 23 on the outer side in the fitted state, and the hooking portion of the headlight lens A is provided at the end on the inner side (see FIG. 6). It is provided with a top forming unit 25 for forming A3. The piece forming unit 25 is
On the peripheral surface A1 of the opening of the lens A, a hook-shaped engaging portion A3 having a substantially triangular cross section is formed. For this reason, a groove 26 having a substantially triangular side surface is formed in the width direction on the tip end surface.

It is made by a pushing spring 27 provided between the side surface and the side surface. That is, the push-in spring 27 embedded in the hole 28 provided on the outer side surface of the ring die 4 abuts on the top base 24 and the retractable top 23 is slid outward by the force for biasing the base 24. .

The sliding is performed by the guide pin 12 provided on the shroud plate 11 and the guide hole 29 opened in the frame base portion 24. Diameter of guide pin 12 and guide hole 29
The inner diameter of the guide pin 29 is substantially the same as the inner diameter of the guide pin 29.
It is located at a position shifted to the outside by an appropriate dimension of 2. On the other hand, the guide pin 12 has a guide portion 12a that is cut off obliquely from the male die 6 side of the outer peripheral surface toward the tip, and the tip portion 12
b is formed so thin that it can enter the guide hole 29 when it is vertically lowered with the frame base 24 sliding outward, and when the guide pin 12 descends together with the male die 6, the tip end is first formed. When the guide portion 12a enters the guide hole 29 and then the guide portion 12a slides into the ring-shaped side of the upper edge of the guide hole 29 and reaches the upper portion of the guide portion 12a, the force exceeds the urging force of the pushing spring 27. Thus, the top base 24 and the retractable top 23 are slid inward.

When the guide pin 12 rises together with the male die 6, it is slid outward by the urging force of the push spring 27, and the moving dimension from the inner sliding position to the outer sliding position is molded by the top molding portion 25. The hooking portion A3 is set to be larger than at least the depth of the groove 26 of the top forming portion 25 so that the hooking portion A3 can be pulled out without being caught by the top forming portion 25 when the ring die 4 is raised.

Since it is possible to form the hanging portion A3, it is possible to assemble the engaging portion A3 into the fitting hole 33 of the headlamp frame member 32 as shown in FIG. It is possible to implement the method of fitting by the concavo-convex, which is used only for the lens mounting means, in the headlight lens A made of glass.
