本発明の方法で製造対象となる、枠体付窓ガラスを、図面を用いて説明する。図１は、枠体付窓ガラスの要部を模式的に示した図である。図２、図３は、図１中のａ−ａ’断面におけるガラス周縁部を模式的に示したものである。図２は、補強部材４が平板の場合、図３は、補強部材４の長手方向に凹部の溝を有する構成の場合を示したものである。ガラス板２の周縁には、軟質樹脂製の枠体３が形成され、枠体３は、硬質樹脂製の補強部材４を備える構成となっている。枠体において、補強部材４が配置されている近傍は、剛性が向上したものとなる。本例では、補強部材４は、一辺に備えたものとなっているが、他の辺にも備えるものとしてもよい。 A framed window glass to be manufactured by the method of the present invention will be described using the drawings. FIG. 1: is the figure which showed typically the principal part of the window glass with a frame. 2 and 3 schematically show the glass peripheral portion in the a-a 'cross section in FIG. FIG. 2 shows the case where the reinforcing member 4 is a flat plate, and FIG. 3 shows the case where the groove of the recessed portion is provided in the longitudinal direction of the reinforcing member 4. A frame 3 made of soft resin is formed on the periphery of the glass plate 2, and the frame 3 is configured to include a reinforcing member 4 made of hard resin. In the frame body, the rigidity is improved in the vicinity where the reinforcing member 4 is disposed. In this example, the reinforcing member 4 is provided on one side, but may be provided on another side.
前記ガラス板２としては、フラットな板ガラスの他に、曲げ加工された板ガラス、強化ガラス、曲げ加工をした強化ガラス、フラットな板ガラスあるいは曲げ加工した板ガラスを用いて作製される合わせガラス等が用いられる。ガラス板２の周縁部には、黒色セラミックスなどによる黒色系のベタ印刷が設けられていてもよい。 As the glass plate 2, in addition to flat sheet glass, bent sheet glass, tempered glass, bent tempered glass, flat sheet glass, laminated glass produced using bent sheet glass, etc. are used. . At the peripheral portion of the glass plate 2, black solid printing by black ceramics or the like may be provided.
枠体３は、スチレン系、オレフィン系、塩ビ系、ウレタン系等の熱可塑性エラストマー（樹脂）を金型内に射出成形して形成される（後段にて、詳細に説明する）。補強部材４には、前記枠体と融合する同系の樹脂で、その樹脂よりも硬度の高い樹脂が使用される。前記枠体と異材質を使用する場合は、プライマー等を補強部材４に塗布する必要がある。
以下に、枠体付ガラス１の製造例を、図面を用いて説明する。図４〜図７の説明は、図３の補強部材４が、長手方向に凹部の溝を有する構成の場合に対応したものであるが、図２に示したような補強部材４が平板の場合であっても、これに準拠して、操作することは可能である。また、図４〜図６は、図１のａ−ａ’断面に対応するもので、金型５、６については断面の要部を示している。図４に示すように、コア金型６に補強部材４と、ガラス板２を配置する。これは前記工程Ａに相当する。次に、図６に示すように、キャビ金型５をコア金型６に合せ、成形型内に空隙８を形成する。これは、前記工程Ｂに相当する。この際、ガラス板２と、補強部材との間には空間あることが好ましい。
The frame 3 is formed by injection molding a thermoplastic elastomer (resin) such as a styrene type, an olefin type, a vinyl chloride type, or a urethane type into a mold (described in detail later). For the reinforcing member 4, a resin of the same type that fuses with the above-mentioned frame is used, and a resin having a hardness higher than that of the resin is used. When using a different material from the frame, it is necessary to apply a primer or the like to the reinforcing member 4.
Below, the manufacture example of the glass 1 with a frame is demonstrated using drawing. The description of FIGS. 4 to 7 corresponds to the case where the reinforcing member 4 of FIG. 3 has a groove with a recess in the longitudinal direction, but the reinforcing member 4 as shown in FIG. 2 is a flat plate Even in accordance with this, it is possible to operate. 4 to 6 correspond to the cross section aa 'in FIG. 1, and the main parts of the cross sections of the molds 5 and 6 are shown. As shown in FIG. 4, the reinforcing member 4 and the glass plate 2 are disposed in the core mold 6. This corresponds to the step A. Next, as shown in FIG. 6, the cavity mold 5 is fitted to the core mold 6 to form a void 8 in the mold. This corresponds to the step B. At this time, it is preferable that there be a space between the glass plate 2 and the reinforcing member.
また、図５に図示したように、補強部材４の長手方向の側辺には、金型凹部６ｂと嵌合する補強部材凸部４ａを（好ましくは凸部４ａを補強部材４に点在させる。）を設けてもよい。このように嵌合する構成とすることで、補強部材４を配置位置にて保持しやすくなる。補強部材４のコア金型６への配置性と、凸部４ａと凹部６ｂとの嵌合しやすさのため、補強部材凸部４ａの形状をドーム状の形状とし、金型凹部６ｂを前記ドーム形状に対応したクレータ状の形状とすることが好ましい。補強部材凸部４ａの大きさは、嵌合性を考慮し、その高さを0.5〜1mm、長さ5〜15mmとし、凸部４ａ間の間隔を、凸部の中心部間にて80〜120mmとすることが好ましい。
Further, as shown in FIG. 5, on the side of the reinforcing member 4 in the longitudinal direction, reinforcing member convex portions 4a to be fitted with the mold concave portions 6b (preferably, the convex portions 4a are dotted ) May be provided. By fitting in this manner, the reinforcing member 4 can be easily held at the arrangement position. Wherein the arrangement of the core mold 6 of the reinforcing member 4, for fitting ease of the protrusion 4a and the recess 6b, the shape of the reinforcing member projecting portion 4a and a dome-like shape, a mold recess 6b The crater-like shape corresponding to the dome shape is preferable. The size of the reinforcing member projecting unit 4a, considering the fitting properties, and the height 0.5 to 1 mm, a length 5 to 15 mm, the spacing between the projecting portions 4a, 80 to at between the center of the convex portion It is preferable to set it as 120 mm.
補強部材４の長手方向の終端部（又は始端部）には（例えば、図１のｂの領域）、図７（ａ）、（ｂ）のように、突起物７を差込む。ここで始端部は、樹脂の射出を開始する側（川上側）、終端部は射出された樹脂が流動する方向（川下側）を意味している。 As shown in FIGS. 7A and 7B, the protrusion 7 is inserted into the end (or the start) of the reinforcing member 4 in the longitudinal direction (for example, the area of b in FIG. 1). Here, the start end means the side where the injection of resin starts (the upstream side), and the end end means the direction in which the injected resin flows (the downstream side).
図８、９に、突起物を補強部材４に差し込む時の突起物の動作例を示す。図８、９は、図１のｂの領域のような、長尺体の補強部材４のｃ−ｃ’断面の端部に、突起物７を差し込む動作を示すものである。図８のようにコア金型６には、補強部材４に向かってスライドすることが可能なスライド部材９が備え付けられており、スライド部材９の補強部材４と対向する面には、突起物７が備え付けられている。スライド部材９を補強部材４の方向にスライドさせることで、図９のように突起物７を補強部材４の端部の側辺部に差し込むことができる。空隙８に樹脂を射出成形するときは、突起物７が補強部材４に差し込まれた状態を保持するようにスライド部材９を固定する。このような動作を行うことで、補強部材４は、その配置位置にて保持しやすくなり、さらには補強部材４の反りの発生を低減しやすくなる。
8 and 9 show an operation example of the protrusion when inserting the protrusion into the reinforcing member 4. 8 and 9 show an operation of inserting the projection 7 at the end of the c-c 'cross section of the reinforcing member 4 of a long body as in the region of b of FIG. As shown in FIG. 8, the core mold 6 is provided with a slide member 9 capable of sliding toward the reinforcing member 4, and a projection 7 is provided on the surface of the slide member 9 facing the reinforcing member 4. Is equipped. By sliding the slide member 9 in the direction of the reinforcing member 4, the protrusion 7 can be inserted into the side of the end of the reinforcing member 4 as shown in FIG. 9. When the resin is injection-molded into the space 8, the slide member 9 is fixed so as to keep the protrusion 7 inserted into the reinforcing member 4. By performing such an operation, it becomes easy to hold the reinforcing member 4 at the arranged position, and it becomes easy to reduce the occurrence of warpage of the reinforcing member 4.
突起物７は、補強部材４への差込み性を考慮すると、突起物７は、金属性の針状体のものが好ましく、工程Ｃにおいては、突起物７を前記補強部材４の表層から0.5〜1ｍｍ深さ差し込むことが好ましい。 In consideration of the insertability into the reinforcing member 4, the protrusion 7 is preferably a metallic needle-like member, and in step C, the protrusion 7 is 0.5 to 0.5 from the surface layer of the reinforcing member 4. It is preferable to insert 1 mm deep.
前記のように凸部４ａと金型凹部６ｂとを嵌合させる場合は、突起物７の差込みは、終端部のみに行ってもよい。終端部の方が、射出樹脂の熱による線膨張と流動により補強部材の反りが発生しやすいからで、突起物７の差込みは、終端部のみであっても補強部材の反り発生低減に効果を奏する。補強部材４の長手方向の終端部（又は始端部）ではなく、その側辺側にあってもよい。凸部４ａと金型凹部６ｂとを嵌合させることなく、枠体付窓ガラスを製造する場合は、突起物７の差込みは、前記補強部材７の長手方向の側辺に、例えば、80〜120mmの間隔で行うものとしてもよい。
Case of fitting the convex portion 4a and the mold recess 6b as described above, the insertion of the projection 7 may be performed only at the end. The end of the reinforcing member is more likely to warp due to linear expansion and flow due to the heat of the injection resin, and the insertion of the projection 7 is effective to reduce the occurrence of warpage of the reinforcing member even if only the end is Play. It may be located on the side of the reinforcing member 4 rather than at the end (or the start) in the longitudinal direction. Without fitting the convex portion 4a and the mold recesses 6b, the case of producing a window glass with the frame, the insertion of the projection 7, in the longitudinal direction of the sides of the reinforcing member 7, for example, 80 It may be performed at intervals of 120 mm.
枠体３を形成するために、空隙８に樹脂を射出する。これは、前記工程Ｄに相当する。枠体３を形成する樹脂の熱により補強部材４は熱膨張し、また樹脂の流動により補強部材が動き、反りやすいものであったが、工程Ｃを備えることで、工程Ｄ時の補強部材４の動き、反りを抑制しやすくなる。 In order to form the frame 3, the resin is injected into the space 8. This corresponds to the step D. The reinforcing member 4 thermally expands due to the heat of the resin forming the frame 3 and the reinforcing member moves due to the flow of the resin, and the reinforcing member is easily warped. Movement and warpage can be easily suppressed.
