[0001]

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

[0002]

2. Description of the Related Art A windshield for an automobile has a seal frame such as a weather strip or a gasket attached to an edge thereof in order to maintain a sealing property when attached to a vehicle body. Some of these seal frames have a reinforcing member embedded in the seal frame in order to strengthen the attachment to the vehicle body.
As a typical example of a seal frame in which a reinforcing member is embedded, Japanese Patent Laid-Open No. 6-156072 “Hard plate insert module assembly window” is proposed, and the technique of the publication will be described in the following figure.

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

[0004]

In the above technique, the pressing piece 103 serves as a fulcrum of the window glass 104 and the edge portion 10
4a is a cantilever. Therefore, the molten resin 10
When the injection pressure of 8 is applied to the window glass 104 as shown by the white arrow, stress is concentrated on the portion contacting 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 embedded in the seal frame while being pressed by the press piece 103, a new press piece 103 is required every time the seal frame is molded. Therefore, it is difficult to reduce the cost of the windshield with a seal frame.

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

Therefore, an object of the present invention is to make it possible to form a seal frame without damaging the plate-like body, to reduce the cost of the seal frame, and to worry about the damage when the seal frame is attached to the vehicle body. To provide the technology without.

And to that clamping step holding the timber, constituting a sealing frame forming method of the plate-like body and a step of injecting the molten resin into the mold cavity.

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-shaped body. Therefore, the injection pressure acts evenly on the upper and lower surfaces of the edge portion of the plate-shaped body, and the downward force and the upward force cancel each other out. Therefore, there is no concern that stress concentrates on the plate-shaped body. Further, 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 prior art.

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

The vertical hole of the reinforcing member can be fitted into the vertical pin to suppress the lateral movement of the reinforcing member, and the lateral slide pin can be inserted into the lateral hole of the reinforcing member to suppress the vertical movement of the reinforcing member. . Therefore, the reinforcing member can be held at a predetermined distance from the plate-shaped body. As a result,
The injection pressure acts evenly on the upper and lower surfaces of the edge of the plate-shaped body, and the downward force and the upward force cancel each other out, so there is no risk of stress concentration on the plate-shaped body. Further, by using the vertical pin or the horizontal slide pin, it is possible to reliably hold the reinforcing member without using, for example, a pressing piece of the related art.
