Abstract

PURPOSE:To improve the appearance and to reduce the cost and weight, by protruding parts which are grasped by a metallic suspender for suspending plate glass during the forming of the glass from one side of the glass at a proper interval. CONSTITUTION:When door glass 11 is manufactured, a sheet of door glass (a) is cut in accordance with the shape of a back door while protruding parts 13, 13' which are grasped by a metallic suspender 12 for suspending the glass (a) during the forming of the glass (a) from one side at a proper interval. The parts 13, 13' are grasped by the suspender 12, and the plate glass (a) is suspended and softened by heating. The softened glass (a) is held between a cavity die 14 and a core die 15, press-formed, and released from the dies to complete door glass 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a molded plate glass used for vehicles such as automobiles and a press molding method thereof.

In recent years, the press molding method, which is a type of glass molding method, has become mainstream in order to improve the strength of automobile door glass or window glass. However, in the press molding method for glass, it is difficult to It has the disadvantage that hanging traces become dented and distorted, and if these are exposed as they are on the surface, it is unfavorable in terms of appearance quality. Therefore, in the past, as shown in FIG.
Pillar finisher 30 to be attached to the car body was made wider and hidden, 4.4' is a screw hole for installation to the car body with wind glass IK drilled, 5Fi looks better, window glass l It is a black print on the periphery. In addition, in the back door glass 6 as shown in Fig. 2 or the roof window glass (not shown) used for the removable roof of the T-bar-7 car, etc., there are hanging marks 7, 7'. In order to handle and hide the weather strip 8, the width H of the weather strip 8 to which the peripheral edge 6aK of the back door glass 6 is fitted must be widened as shown in FIG. There was a problem that it looked bad and looked bad. Reference numeral 8a indicates an adhesive side retaining portion, and reference numeral 9 indicates an adhesive. This is the same when the peripheral edge of the back door glass 6 is curved with the molding 10 shown in FIG. 4, but on the other hand, as shown in FIG. There was a problem that .7' made Shimada look bad.
' is a weather strip that is fitted around the outer periphery of the molding 10 with adhesive 8'.

Incidentally, the above problem can be solved by cutting the holding part of the glass and bringing it closer to the edge of the glass, but if this is done, the holding part of the glass will stretch during heating during molding. Therefore, the dimensions from the end, for example, as shown in FIG.
It requires a certain size of up to ゜2').

Therefore, the invention was made in order to solve the above-mentioned problems of the conventional method, and it is possible to avoid the hanging marks by the mountain fittings without making the ring of the molding, weatherstrits or pillar finisher wider than the motherme. The purpose of this invention is to provide a molded crow that does not come out and a method for pressing and shaping it, and therefore, in the present invention, it is necessary to cut the plate glass that is the material for the Eibori crow. On one side of the hanging sen, there is a spacing between the two in the shape of an Ebi site.

Hereinafter, the present defense will be explained based on the central garden νi; which can be illustrated.

11σ eye movement: A door glass that is attached to a hack door (not shown) of a car, with one side end 11 of a retrieval glass 11.
a K is transmitted to the hanging metal fitting 12 described later and is 6 squares 1
3 and 13' protrude with a gap between them. In addition to the door glass 11, the radius 11b (Si) is made of bamboo along the shape of the back door.

13a and lbm' are hanging marks formed by the hanging fitting 12. (Refer to the 5th trial) Cut a piece of glass a to fit the shape of the back door (not shown) to form the front iC door glass 11. The parts 13 and 13' are cut so as to protrude (see FIG. 6, 0)) Next, the clamping parts 13 and 13' are clamped and suspended by the hanging fittings 12, and then heated. (See Figure 6 ←) When the plate glass a becomes flexible by heating, it is pressed into shape with the cavity mold 14 and the core mold 15 (see Figure 6 (c)). After that, it is removed from the mold. Thus, the door crow 11 as shown in FIG. 5 is completed.

The door glass 11 formed as described above is fitted into the inner groove 1baK of the molding 16, which has an H-shaped cross section, using the glue 17. In addition, according to the shape of the clamping portions 13 and 13' of the door glass 11, the central vertical wall 16b of the molding 16 is cut, and the outer groove 16c K protruding from the outer groove into which the weather strip 18 of the molding 16 is fitted. Although an adhesive depression 19 may be formed (see FIGS. 7 and 8), even if the adhesive reservoir is not formed, as shown in FIG.
Even if you directly press the vertical wall 16bK of the molding 16, the adhesive can be removed at the pupil between the general surface of the one side end 11a of the door glass 11 and the vertical wall 16b, so it is necessary to do so. I) There is no necessity to form a nuisance like Mr.19.

Furthermore, although the above embodiment has been explained using the door crow of the back door, the present invention is not limited to this and can be applied to all press-formed crows.

As mentioned above, according to the invention, in the glass to be press-formed, a holding part that can be attached to the hanging fitting is provided on one side of the glass, so that the holding part is attached to the periphery of the glass. Sufficient joining strength can be obtained even if the molding etc. are loosened, and moreover, there will be no hanging traces. therefore,
Not only does it improve the quality of the appearance, but it also has the advantage of requiring fewer materials for moldings and the like, being inexpensive, and being able to be made into an @i system.
