DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a seal frame of a plate such as a window glass for an automobile and a plate with a seal frame.

[0002]

2. Description of the Related Art A window glass for an automobile has a sealing frame such as a weather strip or a gasket attached to an edge portion thereof in order to maintain a sealing property when the window glass is mounted on a vehicle body. In some of these seal frames, a reinforcing member is embedded in the seal frame in order to firmly attach the seal frame to a vehicle body.
As a typical example of a seal frame in which a reinforcing member is embedded, Japanese Patent Application Laid-Open No. 6-156072, entitled "Hard Plate Insert Module Assy Window", is proposed.

FIG. 17 is a cross-sectional view of a conventional typical plate member with a seal frame. Pins 101, 101 are provided on a molding surface 100a of the lower mold 100, and a hard plate-like material (reinforcing member) 102 is placed on the pins 101, 101. Next, the reinforcing member 102
A spacer (holding piece) 103 is placed on the holding member 103, and a window glass 104 is placed on the holding piece 103. Next, the upper mold 106 is clamped to the lower mold 100. As a result, the wind glass 1
The reinforcing member 102 can be strongly pressed against the pins 102, 102 by the pressing piece 103 via the pin 04, and there is no fear that the reinforcing member 102 will be shifted laterally thereafter. Subsequently, the molten resin 108 is injected into the cavity 107 in the mold, and a gasket (seal frame) in which the reinforcing member 102 is embedded is formed on the edge 104 a of the window glass 104.

[0004]

In the above technique, the holding piece 103 serves as a fulcrum of the window glass 104, and
4a is a cantilever. Therefore, the molten resin 10
When the injection pressure of No. 8 is applied to the window glass 104 as indicated by a white arrow, stress concentrates on a portion of the window glass 104 that is in contact with the pressing piece 103, and a crack 109 is generated in the window glass 104. As a result, the window glass 104 may be damaged.

Further, since the reinforcing member 102 is buried in the seal frame while being pressed by the pressing piece 103, a new pressing piece 103 is required every time the seal frame is formed. Therefore, it is difficult to reduce the cost of the window glass with the seal frame.

Further, when an external force is applied to the window glass when the window glass with the seal frame is attached to the vehicle body, stress concentrates on a portion of the window glass 104 that is in contact with the pressing piece 103, and a crack 109 is generated in the window glass 104. As a result, the window glass 104 may be damaged.

Accordingly, an object of the present invention is to form a seal frame without damaging a plate-like body, to reduce the cost of the seal frame, and to worry about breakage when the seal frame is mounted on a vehicle body. It is to provide a technology without any.

[0011] By pressing the reinforcing member against the one mold with the other mold, the reinforcing member can be held at a predetermined distance from the plate-like body. For this reason, the injection pressure acts uniformly on the upper and lower surfaces of the edge of the plate-like body, and the downward force and the upward force cancel each other. For this reason, there is no fear that stress concentrates on the plate-like body. Also, by pressing the reinforcing member against the one mold with the other mold, the reinforcing member can be securely held without using, for example, a pressing piece of the related art.

According to a third aspect of the present invention, there is provided a molding method for molding a resin sealing frame including a reinforcing member on an edge of a plate-like body, wherein a step of fitting a vertical hole of the reinforcing member into a vertical pin of one of the opened molds is provided. In a state separated from the reinforcing member by a predetermined distance, a step of placing the plate-shaped body on one mold, a mold clamping step of joining the other mold to one mold, and one of the one mold or the other mold A method for forming a plate-shaped seal frame is constituted by a step of extruding the provided horizontal slide pins, inserting the horizontal slide pins into the horizontal holes of the reinforcing member, and injecting the molten resin into the cavity in the mold.

In addition, by using the vertical pins or the horizontal slide pins, for example, the reinforcing member can be securely held without using a conventional pressing member.

According to a fourth aspect of the present invention, in a plate-like body with a seal frame in which a resin-made seal frame including a reinforcing member is formed on an edge of the plate-like body, the reinforcing member is disposed at a predetermined distance from the edge of the plate-like body.
It is characterized in that only the resin of the seal frame is provided in the gap between the reinforcing member and the plate-like body.

Since the reinforcing member is separated from the plate by a predetermined distance, for example, it is not necessary to dispose the conventional "holding piece 103" in the gap between the reinforcing member and the plate. For this reason,
Even when external force is applied to the plate-like body with the plate-like body with the seal frame attached to the vehicle body, the resin between the reinforcing member and the plate-like body is elastically deformed. As a result, there is no possibility that stress is concentrated on the plate-like body.
