DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a window molding with a bright film for forming a rain garter for damping rainwater partially by continuous extrusion.

[0002]

2. Description of the Related Art In a front window of an automobile,
In order to prevent the rainwater on the front window from sneaking into the side window, a window molding installed between the inner edge of the window frame of the front window and the outer edge of the glass fitted into the window frame In some cases, a fin-shaped rain garter is provided integrally to dam the rainwater flowing sideways on the glass surface to prevent the rainwater from flowing into the side window.

On the other hand, it is necessary to connect the glass and the roof as smoothly as possible at the portion along the upper edge of the front window so that rainwater can easily flow to the roof and reduce wind noise. Therefore, the cross-sectional shape of the window molding when the rain garter is provided must be different between a portion along the upper edge of the front window and a portion along the side edge.

[0004] As a method of continuously molding a window molding having portions having different cross-sectional shapes from each other with a rubbery synthetic resin material, a window molding is removed from a die head so that the shape in which the fins are raised is normal. By continuously extruding and pressing a pressure roller provided on the exit side of the die head against the fin of this window molding, a molding method in which the fin is tilted over a predetermined range, It is proposed in Japanese Patent Application Laid-Open No. Hei 5-213060.

[0005] On the other hand, in order to enhance the decorativeness, a glitter film having a metallic texture or the same color as the vehicle body may be attached to the outer surface of the window molding. When this is applied to the above-mentioned window molding having a fin, it is conceivable to attach a glitter film to the outer surface of the fin.

[0006]

However, according to the above-mentioned forming method, the pressure roller having the contour corresponding to the fin portion in the collapsed state is linearly moved in the direction perpendicular to the direction in which the window molding is extruded. As a result, a pressing force is applied to the fins, so that in the process of pressing down the pressure roller, the surface of the pressure roller and the surface of the fin attached to the glittering film have a relative width direction relative to the fins. Slip occurs. Therefore, there is a possibility that the glitter film may be stretched or twisted due to excessive force applied to the glitter film.

[0007] The present invention has been devised to solve such disadvantages of the prior art, and its main objects are as follows.
An object of the present invention is to provide an apparatus for manufacturing a window molding with a glitter film, which can easily cope with the presence or absence of a rain garter for damping rainwater and does not adversely affect the glitter film attached to the surface.

[0008]

SUMMARY OF THE INVENTION According to the present invention, there is provided, in accordance with the present invention, a main part which is continuously mounted in a gap between a window frame of an automobile and a glass, and a main part which is provided on an outer surface of the main part. Having a fin portion, being extruded using a die head having a constant cross section, and keeping the glitter film-attached surface of the fin portion in a predetermined range in a window molding in which a glitter film is attached to the fin portion. The structure of the manufacturing apparatus for a window molding with a brilliant film for crushing across, an arm that is engaged at one end with an arcuate guide and is tilted and driven in a predetermined angle range, and an outer surface of the fin after crushing. And a movable sizing jig having a corresponding contour and provided at a free end of the arm.

[0009]

According to such a configuration, the tilt center of the arm can be freely set, so that the movable sizing jig can be tilted about the base of the fin. Therefore, the fins can be smoothly laid down without causing a relative displacement between the contact surfaces of the bright film attachment surface of the fins and the movable sizing jig.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below in detail with reference to specific embodiments shown in the accompanying drawings.

FIG. 1 shows a front window portion of an automobile equipped with a window molding to which the present invention is applied.
And the window frame 3.

As shown in FIG. 2 and FIG.
Is formed stepwise by bending the inner peripheral edge of the opening formed from the roof 4 to the front pillar 5 toward the interior of the vehicle, and then bending the edge toward the center of the opening. ing. A windshield 2 is mounted via a window molding 1 on a bottom 6 which is one step down from the outer surfaces of the roof 4 and the front pillar 5.

The window mold 1 is a windshield 2
The base 7 is provided along the cut end surface of the outer periphery of the rim, the first lip 8 which is in close contact with the inner peripheral edge of the window frame 3, that is, the outer surface of the roof 4 and the front pillar 5, and the inner wall 9 of the stepped portion is resilient. And the third and fourth lips 11.1, which contact the inner and outer surfaces of the outer peripheral edge of the windshield 2, respectively.
And 2.

The window mold 1 is mounted between the third and fourth lips 11 and 12 so as to sandwich the peripheral edge of the windshield 2. A gap defined by the body-side surfaces of the second lip 10 and the fourth lip 12 and the bottom 6 and the inner wall 9 of the window frame 3 is filled with an adhesive 13 having a sealing property. I have.

A fin 14 is provided upright at an intermediate portion between the two lips 8 and 11 on the outer surface of the main portion of the window molding 1 composed of the above-described portions. This fin 14
The upper edge of the windshield 2, that is, the portion connected to the roof 4, is crushed so as to press against the outer surface of the third lip 11 (see FIG. 2), and the side edge of the windshield 2, that is, the portion connected to the front pillar 5. Stands at an appropriate angle on the glass surface (see FIG. 3). A bright film 15 is attached to the outer surface of the fin 14.

As described above, in order to prevent the rain water that the wiper scrapes sideways during running in rainy weather from flowing into the side window, a rain for damping the rain water on the side edge of the windshield 2 is required. It is necessary to provide a garter. On the other hand, in order to reduce wind noise and improve aerodynamic characteristics, it is preferable to reduce the step from the upper edge of the windshield 2 to the surface of the roof 4 as much as possible. Therefore, it is preferable that the cross-sectional shape of the window molding provided in the front window changes continuously according to the portion on the window frame.

Therefore, in the present invention, a sizing jig provided at the entrance side of a water tank for storing cooling water for cooling the window molding 1 having a constant cross section which is continuously extruded from a die head (not shown). However, the sectional shape is changed by partially correcting it.

FIG. 4 shows a schematic configuration of a straightening device according to the present invention. This device is provided with a water tank 16 for storing cooling water.
A base frame 21 installed on the entrance side of the base frame 21, an arm 24 having one end fixed to a carriage 23 engaged with an arc-shaped guide rail 22 provided on a vertical plate 21a of the base frame 21; A ball screw type driving device 25 for giving a swiveling motion along the arm 24, and a sizing jig support 26 attached to the vertical plate 21a of the base frame 21.
The movable portion 17a of the sizing jig 17 is attached to the free end of the arm 24.

In the present device, the screw portion 25a of the driving device 25 is rotationally driven by the electric motor 25b,
Ball bush 25c screwed into screw 25a
Moves in the direction of arrow A, and this movement is
The movable portion 17a of the sizing jig 17 is tilted in the direction of arrow B by transmitting to the arm 24 via Thereby, a correction load can be applied to the fins 14 in an arbitrary range of the window molding 1. In addition, vertical board 2
1a and the sizing jig support 26 are attached to the horizontal plate 21b so as to be able to move up and down. The position can be matched. After adjusting the height with the screw handle 27, the lock plate is tightened to fix the positions of the vertical plate 21a and the sizing jig support 26.

With this apparatus, the portion corresponding to the front pillar 5 is formed without the straightening load applied to the fin 14 with the arm 24 upright (see FIG. 5). The portion corresponding to the roof 4 applies a correction load to the fin portion 14 by tilting the arm 24, and the fin portion 14
It is pressed against the lip 10 and molded (see FIG. 6). In this manner, a shape in which the fins 14 are upright and a shape in which the fins 14 are laid down can be selectively obtained, and the fins 14 in the upright state can be used as a rain garter.

In the process of applying a correction load to the fins 14, the movable part 17a of the sizing jig 17 and the fins 1
When the relative sliding of the fins 14 in the width direction occurs between the contact surfaces with the fins 4, the brilliant film 15 is stretched by applying an excessive force to the brilliant film 15 attached to the surface of the fins 14. May be kinked. According to the device of the present invention, the tilt center of the arm 24 and the fin 14
The trajectory of the arm 24 can be set so that the base of the arm 24 is almost completely aligned with the base of the sizing jig 17 without any relative displacement between the fin 14 and the movable surface 17a of the sizing jig 17. 14 can be defeated.

The movable portion 17a of the sizing jig 17
Cooling water is supplied from a water passage (not shown) provided in the movable portion 17a between the contact surfaces of the movable portion 17a and the fin portion 14, so that the portion to which the correction load is applied is immediately cooled. To enhance the molding effect and reduce the sliding friction with the window molding 1.

[0023]

As described above, according to the present invention, it is possible to continuously extrude a molding having a substantially constant cross-sectional shape, and to change the cross-sectional shape according to the portion. Moreover, since the movable sizing jig can be tilted about the base of the fin, the relative displacement in the width direction of the fin between the movable sizing jig and the contact surface of the fin with the glitter film-attached surface can be obtained. Since it does not occur, the glitter film does not stretch or twist due to excessive force being applied to the glitter film.
