Abstract

PURPOSE:To dissolve trouble in the manufacturing method with the conventional integral mold for manufacturing a modular glass and provide the manufacturing method of the modular glass, by which neither crack in glass nor the leakage of resin on the surface of the glass develops, even when the thickness and form of the glass vary. CONSTITUTION:In the manufacturing method of a modular glass 1, which is produced by integrating resin part and glass 2 with each other, the resin part consists of upper resin part 4a and lower resin part 4b, which are separately and integrally molded. The manufacturing method of the modular glass 1 concerned is performed by integral bonding between the glass 2 and the upper resin part 4b, between the upper resin part 4a and the lower resin part 4b and between the lower resin part 4b and the glass 2 by adhesive.

Description

DETAILED DESCRIPTION OF THE INVENTION [0001] [Industrial Field of Application] The present invention relates to a method for manufacturing module glass for automobiles.

[0002] [Prior Art] Conventionally, a module glass 1 for an automobile as shown in FIG. 4 is generally composed of a glass 2, a stainless steel part 3, and a resin part 4, as shown in FIG. ing. As shown in FIG. 3, the manufacturing method is to incorporate the glass 2 and the stainless steel part 3 into the resin part 4, and integrally mold them using an injection molding machine equipped with an integral mold 5. .

[0003] However, when such a manufacturing method is used, variations occur in the thickness and shape of the glass 2, which may cause problems such as the glass 2 being broken by the mold 5 during integral molding.

[0004] Furthermore, if a gap is created between the mold 5 and the second glass surface, resin leakage will occur at a portion 6 in FIG. 3, which may cause problems in terms of appearance.

[0005] [Problem to be solved by the invention] Therefore, the problem to be solved by the present invention is to solve the above-mentioned problems when manufacturing module glass, and to solve the problem even if there are variations in the thickness and shape of the glass. Another object of the present invention is to provide a method for manufacturing module glass that does not cause glass breakage or resin leakage onto the glass surface.

[0006] [Means for Solving the Problems] In order to achieve the above object, the present invention provides a method for manufacturing module glass in which a resin part and glass are integrated, in which each of the resin parts is It is composed of a resin upper part and a resin lower part that are integrally molded separately, and then the crow, the resin upper part, the resin lower part, and the resin upper and lower parts are fitted together.
This is a method for manufacturing module glass in which the bonding surfaces are bonded and integrated with an adhesive.

[0007] [Function] In this way, the resin part is not integrally molded by incorporating glass, but is divided into two parts, an upper part and a lower part, and these parts are fitted onto the glass afterwards. It is no longer affected by variations in plate thickness and shape, and as a result, both the above-mentioned glass cracks caused by the mold and resin leakage due to gaps between the mold and the glass surface are eliminated. This will be prevented.

[0008] [Example] FIG. 1 is an explanatory diagram of an example of the present invention, in which 2 is glass, 3 is a stainless steel part, 4a is a resin upper part, and 4
b is the resin lower part, and 7 is the adhesive part. In this figure, the resin part of the present invention is composed of a resin upper part 4a and a resin lower part 4b, each of which is integrally molded separately, and then these are attached to the glass 2 using an adhesive. Part 7・
・This is a method for manufacturing module glass in which the bonding surfaces are bonded and integrated with each other.

[0009] That is, in this invention, instead of integrally molding the resin part with the glass incorporated as in the past, this resin part is divided into two parts, the resin upper part 4a and the resin lower part 4b, and the glass 2 is On the other hand, these are configured so that they are adhesively integrated in a manner that they are later fitted.

[0010] [Effects of the Invention] As explained above, according to the present invention, the resin part can be integrally molded in this way without using an integral molding mold and incorporating glass as in the conventional method. The resin part is divided into two parts, an upper part and a lower part, and these parts are glued and integrated into the glass, so that they are not affected by variations in the thickness or shape of the glass. This eliminates both the glass cracking caused by the mold and the occurrence of resin leakage due to gaps between the mold and the glass surface, which improves the design and reduces the defective rate. This also results in a reduction in costs.
