[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin molding die and a plate with a resin frame for integrally forming a resin frame around the periphery of a plate having a corner portion such as a window of a vehicle or a window of a building. The present invention relates to a method for producing a body.

[0002]

2. Description of the Related Art In a vehicle or a building, a resin frame such as a synthetic resin molding or gasket is attached to the periphery of a plate-shaped body such as a glass plate or a plastic plate in order to enhance decorativeness or sealing property. It is common practice to obtain a plate-like body with a resin, and fit the resin-framed plate-like body into an opening, such as a window, and attach it. Examples of the material of the resin frame include polyvinyl chloride, a copolymer of vinyl chloride and ethylene, a styrene-based resin, an olefin-based resin, a urethane-based resin, a silicon-based resin, and a sol-like vinyl chloride.

FIGS. 16 and 17 show an example of a plate-like body with a resin frame for a vehicle window. This plate-shaped body with resin frame is
One side of plate-like body 1 such as glass plate or resin plate (inside of car)
The resin frame 3 is integrally fixed to the peripheral edge of the resin frame with an adhesive 2. In the example of FIG. 16, the thickness of the resin frame 3 fixed to the peripheral edge of the plate-like body 1 is different in the width direction (the outside and the inside of the frame), and the inside of the plate-like body 1 is thick. The outer portion of the plate-like body 1 is a thin portion 4b. In the example of FIG. 17, a case is shown in which the resin frame 3 fixed to the peripheral edge of the plate-like body 1 with a uniform thickness has a projecting portion 5 that extends further outward from the end surface of the plate-like body 1. I have.

As a method for manufacturing a plate-like body with a resin frame as shown in FIGS. 16 and 17, there are the following methods.

FIG. 18 shows an example of an apparatus for manufacturing a plate-like body with a resin frame. In the apparatus shown in FIG.
The resin frame material is extruded with a predetermined cross-sectional shape to form a molded body 8 for the resin frame once, the molded body 8 is supplied to the pressure bonding member 9, and the drive robot 11 having the suction cup 10
The peripheral edge of the plate-like body 1 supported by the above is fitted to the pressure bonding member 9. At this time, the adhesive 2 is applied in advance on one surface (the upper surface in FIG. 18) of the peripheral edge of the plate-like body 1. As described above, the molded body 8 is pressed against the plate-like body 1 by the pressure-bonding member 9.
Is moved with respect to the pressure bonding member 9, the molded body 8 is fixed to one surface of the peripheral edge of the plate-like body 1 with the adhesive 2,
Is formed (first method). In FIG. 18, the molded body 8 extruded from the molding die 7 is
, Is lifted to the upper part of the plate-like body 1, is guided to the upper surface of the plate-like body 1, and is pressed by the pressing member 9. In this case, the guide roller 13 can be omitted.

FIGS. 19 and 20 show an apparatus in which the resin frame 3 is formed by directly extruding the resin frame material 12 from the molding die 7 on the upper surface of the peripheral edge of the plate 1. 19 and 20, the plate-shaped body 1 is fixed, and the resin frame material 12 is extruded while the forming die 7 is moved along the periphery of the fixed plate-shaped body 1 as shown by an arrow a. Thereby, the resin frame 3 is formed on the periphery of the plate-like body 1 (second method).

In the apparatus shown in FIGS. 19 and 20, the forming die 7 is fixed, and the plate 1 is movably supported by a device such as the drive robot 11 shown in FIG. The resin frame 3 is formed on the periphery of the plate-like body 1 by extruding the resin frame material 12 from the molding die 7 while moving the plate-like body 1 along the fixed forming die 7 as shown by an arrow b. (Third method).

[0008]

When the periphery of the plate-like body 1 is a straight side or a curve having a large radius of curvature, FIG.
8 and the relative movement between the forming die 7 and the plate-shaped body 1 in FIGS. 19 and 20, and the relative movement between the forming die 7 and the plate-shaped body 1 in FIGS. It is relatively easy to form the resin frame 3 continuously along the peripheral edge of the plate-like body 1 by the method described above.

However, as shown in FIGS. 18 and 20, the plate-like body 1 has a corner 14 (hereinafter referred to as a corner) having a small radius of curvature between one adjacent side 1A and the other side 1B. In some cases). As a specific example of the corner portion 14, the inner angle may be an acute angle, a right angle, or an obtuse angle.

In order to continuously form the resin frame 3 in such a corner portion 14 of the plate-like body 1, the relative movement between the press-fitting member 9 and the plate-like body 1 or the forming die 7 and the plate-like body 1 Is required to be performed in a short time and at an accurate timing suitable for the position of the corner portion 14, but such control is practically very difficult. In order to address this problem, it is conceivable to reduce the speed of the relative movement, but in this case, the productivity is significantly reduced.

Further, even if the resin frame 3 can be formed in the corner portion 14, the resin frame 3 formed in the corner portion 14 is easily deformed. For this reason, it has been difficult to form the resin frame 3 having a uniform and good shape continuously at the corner portion 14.

The present invention has been made in view of the above-mentioned circumstances, and has as its object to provide a peripheral portion of a plate-like body having a corner portion,

In addition to the sliders 27 and 28, a slider 37 is provided to enter the lower part of the shutters 25 and 26 on the front surface of the third opening 20. The slider 37
Can be retracted upward so as not to interfere with the resin frame 3 already formed as described above.

According to the die body 33 shown in FIG. 15, the three corner portions 14a, 14b,
Resin frames 3 having different thicknesses in the width direction can be continuously formed on four sides 1A, 1B, 1C, and 1D including 14c.

In the above-described embodiment, a case has been exemplified in which resin frames having different thicknesses in the width direction are continuously formed on the periphery of the plate-like body. However, the shutters arranged in front of each opening are simultaneously opened and closed. It is possible to easily form a resin having a uniform thickness in the width direction by using a shutter having a single structure or a single structure, and this method is also included in the present invention.

Further, if the lower side of each shutter is formed to have a slanted shape, a resin frame whose thickness in the width direction is changed in slope can be used in addition to a resin frame whose thickness in the width direction is changed stepwise.

Further, the present invention is not limited to the above-described embodiment, and the specific shape of the die body can be variously changed, and the number of shutters provided on the front surface of each opening can be arbitrarily changed. It is optional to add various changes without departing from the gist of the present invention.

[0040]

As described above, according to the present invention, there is provided a die body having at least three openings so that at least three directions are the extrusion directions of the resin material in the same plane. A plurality of shutters that can be opened and closed and whose opening interval can be adjusted are arranged in parallel on the front surface of each opening of the main body, and the extrusion direction and the extrusion amount of the resin material are set by opening and closing the shutter and adjusting the opening interval. By moving the die body relative to the plate-like body, there is an effect that resin frames having different thicknesses in the width direction can be continuously formed on at least three sides including the corners of the plate-like body peripheral edge.

By providing a slider which moves forward and backward immediately below a shutter arranged in front of the opening and which can open and close the opening from a direction perpendicular to the direction in which the shutter opens and closes the opening, a resin frame is provided at the corner. This has an effect of preventing a problem that a gap is formed behind the inner end face of the resin frame already formed and the resin material flows out. Further, the resin frame formed in the previous step is prevented from being deformed by being pulled by the resin frame formed on the next side due to the entry of the slider into the lower portion of the shutter, and a resin frame having a good shape is formed at the corner portion. There is an effect that can be done.

Further, the die body is provided with a cooling device for cooling the resin material in each opening, so that the resin material in the opening is cooled and hardened when the direction of forming the resin frame in the corner portion is changed. Therefore, there is an effect that the problem that the resin material flows out due to the operation of the shutter can be prevented.
