Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for extruding a weather strip on the periphery of a windshield glass,
In particular, the present invention relates to a technique for extruding a weather strip having a cross section that varies depending on the location.

[0002]

2. Description of the Related Art For example, a weather strip 4 provided around a front windshield glass 3 of an automobile shown in FIG. 1 needs to have a different cross section at an upper portion 4A and a side portion 4C. That is, FIG.
As shown in (c), the groove 8 extending along the side edge of the windshield glass 3 is required in the side portion, and the groove 8 is not required in the upper portion as shown in (B).

A technique for extruding a weather strip 4 having a cross section that varies depending on the location as described above is disclosed in Japanese Patent Laid-Open Publication No. Hei.
It is disclosed in Japanese Patent No. 128721. With this technology,
As shown in FIG. 22, extrusion molding is performed while moving a movable die having an orifice 220 relative to a fixed die having an orifice 210. In this way, the portion where the orifices 210 and 220 overlap (i.e., the Boolean product of the geometry) has a substantially orifice shape, and a weather strip having a cross section that matches the substantially orifice shape is extruded. For example, in the upper portion, the orifices 210 and 220 are placed in the positional relationship shown in FIG. 22 (B1), and the weather strip 4A that does not form the groove 8 with the windshield glass 3 is extruded. On the other hand, in the side portion, the orifices 210 and 220 are placed in the positional relationship shown in FIG.
The weather strip 4C that forms the is extruded. As a result, the weather strip 4 shown in FIG. 20 (D) is extruded.

This technique is a very effective technique for integrally molding the weatherstrip 4 having a different cross section depending on the location. However, since this technique only molds the weatherstrip regardless of the windshield glass, A step of fitting the once-molded weather strip into the peripheral edge of the windshield glass is required. Further, in this step, the weather strip may be twisted. Further, the positional relationship between the peripheral edge of the glass and the weather strip in the longitudinal direction may shift, and a weather strip having an unintended cross section may be fitted into a predetermined position of the glass.

The technique of US Pat. No. 5,057,265 has also been proposed. In this technique, as shown in FIG. 21, a die 331 having an orifice 331a is extruded while moving along the peripheral edge of the windshield glass 3.
As a result, the weather strip 4 is extruded along the peripheral edge of the windshield glass 3. According to this technique, since the weather strip 4 is extrusion-molded directly on the peripheral edge of the windshield glass 3, it is not necessary to fit the weather strip on the peripheral edge of the windshield glass 3. In the technique of US Pat. No. 5,057,265, the cross section of the weatherstrip formed is uniform. Further, since the adhesive material (urethane) is used, the weather resistance is insufficient, and it is extruded only on the inside of the vehicle. More die 3
In order to move 31 with the glass end face as a guide,
As the glass size increases, so does the outer edge of the weatherstrip.

[0006]

The problem shown in FIG. 22,
That is, the technique of extruding while changing the substantial orifice shape by moving the movable die relative to the fixed die, and the technique shown in FIG. 21, that is, moving the die along the peripheral edge of the windshield glass. It is expected that weather strips having different cross sections depending on locations can be extruded along the periphery of the windshield glass in combination with the extrusion technique. However, there is a limit to the cross-sectional shape that can be formed by this technique.

As shown in FIG. 22, a ridge 6a extending toward the center of the windshield glass 3 is provided on the outside of the cabin of the weather strip 4, and the ridge 6a contacts the windshield glass depending on the location. In order to separate from the windshield glass depending on the place, as shown in (A1) of FIG. 22, it is necessary that the orifice 210 on the fixed die side extends vertically with the width of the protrusion 6a. is there. Then, the orifice 220 on the movable die side moves up and down at this portion, and the height at which the protrusion 6a is formed is changed depending on the location. In this case, regardless of the windshield glass, that is, in the place where only the weatherstrip is formed, the interference between the movable die and the windshield glass does not pose a problem, and the technique of FIG. 22 can be implemented. However, if extrusion molding is performed along the periphery of the windshield glass, the windshield glass and the movable die interfere with each other, and the technique of FIG. 22 cannot be directly executed. When the movable die is designed in such a range that the movable die does not interfere with the windshield glass, it is possible to form a weather strip having a thickness H different depending on the location as shown in (D2) of FIG.
Cannot be molded. In order to make the groove 8, it is necessary to provide a wall for forming the groove 8 on the side of the movable die. However, if there is a windshield glass, it is possible to avoid interference between this wall and the windshield glass. Because there is no.

The present invention solves such a problem, and a weather strip is extruded on the periphery of the windshield glass without the movable die interfering with the windshield glass, and with the groove 8 depending on the location and without the groove 8 depending on the location. It is the one to be molded. Further, with this technique, it is intended to provide a windshield glass in which a groove 8 exists depending on a location and a weather strip where the groove 8 does not exist depending on a location is directly extrusion-molded on the periphery of the windshield glass.

[0009]

The above object is a method of extruding a weatherstrip having a different cross section depending on the location on the periphery of the windshield glass, and the fixed die side having a slot into which the periphery of the windshield glass is inserted. And a step of inserting the peripheral edge of the windshield glass into the orifice, and having a wider orifice than the width of the portion of the fixed die type orifice that contacts the windshield glass, and a replenishing passage communicating with the wide portion is formed. A method for manufacturing a windshield glass with a weatherstrip having an irregular cross section, which comprises a step of extruding while moving the movable die relative to a fixed die while relatively moving the peripheral edges of the fixed die and the windshield glass. Will be resolved.

Further, according to the present invention, there is provided a windshield glass with a weatherstrip in which a weatherstrip is extruded around the periphery of the windshield glass, and a ridge extending toward the center of the windshield glass outside the cabin of the weatherstrip. Is formed, the ridge and the windshield glass are in close contact with the upper part of the windshield glass, and the ridge and the windshield glass are separated from each other in the side part of the windshield glass. A windshield glass with a weatherstrip having a modified cross section, which is characterized by having grooves formed, was created.

[0011]

[Operation] (A1) of FIG. 23 shows the orifice 251 on the fixed die side.
A is illustrated, and 251b is a slot into which the windshield glass 3 is inserted. On the other hand, (A2) shows the orifice on the movable die side. The orifice on the movable die side is an orifice 252b having the same width as the orifice 251a.
And a wide portion 252a that projects laterally from it. A supply path (not shown) communicates with the wide portion 252a inside the movable die.

Now, when the fixed die and the movable die are placed in the positional relationship shown in FIG. 23 (B1), in addition to the portion formed through both the orifices 251a and 252b, the replenishment passage is passed through the wide portion 252a. An extruded product in which the part to be molded is integrated is molded. As a result, the weather strip having the cross section shown in (B2) is formed. On the other hand, the fixed die and the movable die are shown in FIG.
In the positional relationship shown in (C1) of No. 1, the portion formed through the orifice 251a and the orifices 251a and 252
An extruded product in which a portion formed through both b and a portion formed through the wide portion 252a from the replenishing passage are integrated is formed. As a result, a weather strip having a cross section shown in (C2) is formed. Here, the groove 8 is formed.

As described above, according to this method, the weather strip does not interfere with the movable die and the windshield glass, and the groove exists depending on the location, and the weather strip does not exist depending on the location along the peripheral edge of the windshield glass. It becomes possible to perform extrusion molding, and the windshield glass with a weatherstrip having a modified cross section according to the present invention is manufactured.

The fixed die orifice 2 shown in FIG.
When 61a and the orifices 262a and 262b of the movable die are used, as illustrated in (B2) and (C2), a lip 6c that is in close contact with the surface of the windshield glass 3 is formed, and in the upper portion of the windshield glass ( As shown in B2), the lip 6c is thin, the lip 6c is thick at the side portion of the windshield glass, and the groove 8 extending from the central portion side of the windshield glass 3 is formed in the thick portion 6c. A formed windshield glass with a weatherstrip having a modified cross section is manufactured.

The windshield glass manufactured in this manner has the weatherstrip already attached, and it is not necessary to attach the weatherstrip around the windshield glass. Moreover, the groove may or may not exist depending on the location, and the function required for the weather strip can be sufficiently fulfilled.

Next, a manufacturing apparatus for the windshield glass 2 with a weather strip having the above-mentioned structure will be described with reference to FIGS. In FIG. 5, which is a perspective view of the entire manufacturing apparatus, the manufacturing apparatus includes a die device 11 assembled to the front end of the extrusion molding machine 10, a glass holding device 60 disposed on the side of the die device 11, and the glass holding device. A glass charging device 64 for 60, a glass removing device 95,
Glass receiving shelf device 96 for glass feeding device 64
And a glass carry-out shelf device 103 for the glass take-out device 95.

6 and 7 showing the die unit 11 of the extrusion molding machine 10, a die body 13 is provided at the tip of the extrusion molding machine via a joint pipe 12 for supplying the extruded resin material P. Installed. Die body 13
Includes a fixed die 131 installed in a fixed state, and a movable die 132 arranged at an end of the fixed die 131 in the weather strip extrusion direction.

The movable die 132 is supported by a guide groove 133 recessed in the fixed die 131 so as to be movable in the vertical direction in the drawing, and a continuous rod 134 connected to the upper edge of the movable die 132. Is connected to a vertical drive device (not shown).

An orifice 131a shown in FIG. 8 is formed in the fixed die 131, and a slot 131b communicates with this orifice 131a. The slot 131b is for inserting the peripheral edge of the windshield glass, and when the windshield glass is inserted into the slot 131b, a clearance of about 0.1 mm remains on both sides of the windshield glass. By this clearance, the periphery of the windshield glass and the fixed die 13
1 can be moved relative to each other. Extruded resin material P
If this clearance is about 0.1 mm due to the viscosity and the like, the extruded resin material will not protrude from this clearance. In the figure, 131c communicates with the joint pipe 12 inside the fixed die 131, and the extruded resin material is extruded from the orifices 131a and 131c.

The movable die 132 has a shape shown in FIG. 9, and has an orifice 132b having the same width as the orifice 131a on the fixed die side, and a wide portion 132a extending to the left in the drawing from the orifice 132b. There is. The movable die 13
A replenishment passage 132c is formed on the back surface and inside of the second passage so as to connect the opening 131c on the fixed die side and the wide portion 132a.
Further, the escape orifice 132d is formed obliquely.

The positional relationship between the movable die 132 and the fixed die 131 when the movable die 132 is at the upper limit position (state of FIG. 7) is shown in FIGS. It is apparent from FIG. 10 that the support piece 7 is molded by the orifice 131a on the fixed die side. Orifice 131a on the fixed die side
And the leg portion 5 by the wall 132e (see FIG. 9) on the movable die side.
Is molded. Further, the movable die side orifice 132b
Thus, the panel-side protruding strip 6b is formed. Further, from the opening 131c on the fixed die side to the wide portion 1 through the replenishment path 132c.
The glass side protrusion 6a is molded by the extruded resin material reaching 32a. At this time, the groove 8 is formed by the wall 131d (see FIG. 8) on the fixed die side. The flow of the resin from the opening 131c to the wide portion 132a via the replenishment path 132c is well understood from FIGS. 11 and 12.

In the case of this embodiment, even if the cross-sectional shape of the weather strip changes, the amount of resin extruded from the die as a whole is kept constant. For this purpose, an escape orifice 132d is provided. When the movable die is located above as shown in FIG. 10, the legs 5 are long and the cross-sectional area of the weather strip is large. At this time, the overlapping area of the orifice 131a on the fixed die side and the escape orifice 132d is small, and the escape orifice 132d
The amount of the resin 4D extruded from the resin is relatively small (the flow of the resin escaped to the escape orifice 132d is as shown in FIG.
Well understood).

On the other hand, FIG. 15 shows a position where the movable die 132 is lowered, that is, a state in which the upper portion shown in FIG. 6 is being formed. In this case, the groove 8 is not formed. In addition, the amount of escape from the escape orifice increases. Obviously, even in this positional relationship, the windshield glass 3 and the movable die 132 do not interfere with each other.

In the case of this embodiment, the sum of the cross-sectional area of the weather strip 4 and the cross-sectional area of the resin escaping from the escape orifice 132d is always kept constant. Therefore, even if the positional relationship of the movable die with respect to the fixed die is changed, the extrusion pressure and the like are kept constant, and the weather strip can always be extrusion-molded under the same conditions.

In this case, the movement of the movable die 132 is
It is controlled so as to be synchronized with the position movement of the windshield glass 3 and the die device 13 which will be described later. That is, the drive device for the movable die 132 is the windshield glass 3
Is controlled on the basis of the position data of the windshield glass 3 so that the weatherstrip having a predetermined cross-sectional shape corresponding to each portion of the windshield glass 3 is accurately formed without displacement. There is.
In particular, the corner strip 4B is accurately formed at the corner portion.

In the case of the present embodiment, the glass holding device 60 uses the die device 13 in accordance with pre-tated data.
Change position with respect to. For this reason, the outer shape of the windshield glass with a weather strip is predetermined. That is, even if there are variations in the shape and size of the glass, the width dimension of the leg portion 5 only changes, and the outer shape of the windshield glass with a weather strip always has the same shape and size. For this reason, it is not necessary to attach it to the vehicle body panel, and it is not necessary to make the precision requirement for the glass too high.

The die device 11 is relatively moved along the rounded surface of the first corner portion of the windshield glass 3. Furthermore the first
The tilting table 57 corresponding to the curvature of the glass surface at the corner
Is tilted, the first corner portion of the windshield glass 3 is kept horizontal with respect to the extrusion molding port of the die device 11.

The first corner portion of the windshield glass 3 passes through the extrusion molding port of the die device 11, and as shown in FIG. 19, the right edge of the peripheral edge of the windshield glass 3 reaches the extrusion molding port. By the way, the tilting base 57 is tilted corresponding to the curvature of the right edge portion of the peripheral edge of the windshield glass 3, and the right edge of the peripheral edge of the windshield glass 3 is kept horizontal with respect to the extrusion port. The first and second swivel arms 36 and 41 move the right edge of the peripheral edge of the windshield glass 3. Then, a side strip 4C is provided on the right side edge of the windshield glass 3.
Is extruded.

The movable die 132 of the die device 11 is moved from the position shown in FIG. 7 to the position shown in FIG. 6 at the side portion from the upper right end of the peripheral edge of the windshield glass 3 to the second corner. While extruding, the corner strip 4B is extruded while the bulging thickness of the weather strip 4 is reduced. In this case, the movement of the movable die 132 is controlled so as to be synchronized with the relative movement between the windshield glass 3 and the die device 11, as described above. For this reason windshield glass 3
A molding having a predetermined cross-sectional shape corresponding to each of the parts is accurately formed without displacement, and particularly, in the corner portion and its vicinity, the corner strip 4 is formed.
The variable expanded wall portion of B is formed with high positional accuracy. If only the weatherstrip is molded and then fitted into the glass, the positional relationship may be displaced, and for example, corner strips may stick out on the side of the glass. According to the present invention, such a problem does not occur.

After the extrusion molding of the corner strip 4B is completed and the upper edge of the peripheral edge of the windshield glass 3 reaches the extrusion molding port of the die device 11, the extrusion molding of the up-pass trip 4A is performed. In this case, die device 11
The movable die 132 is set to the position shown in FIG. 6, and the extrusion port is reduced to the minimum opening area.

While the peripheral portion of the windshield glass 3 held by the glass holding device 60 in this way is kept horizontal by the moving device 24, it is always inserted into the extrusion molding port of the die device 11 at a constant insertion depth. It is inserted and moved. At this time, since the movable die 132 provided in the die device 11 is controlled so as to be synchronized with the relative movement between the windshield glass 3 and the die device 11, the outer shell shape of the extrusion molding port corresponds to the glass position. The extrusion molding is performed while changing the temperature. As a result, the weather strip 4 having a different cross-sectional shape depending on the location is accurately extruded and molded on the peripheral edge of the windshield glass 3 with no positional deviation, and at the same time, the same adhesive is applied to the peripheral edge of the windshield glass 3 to prevent the weather strip 4 from being extruded. The weather strip 4 is integrally bonded to the peripheral edge of the shield glass 3. When the entire length of the weather strip 4 is extruded along the peripheral portion of the windshield glass 3, the supply of the extruded resin material P to the material supply path of the die device 11 is temporarily cut off.

(Forwarding Step) When the supply of the molding material is cut off, the slide table 26 is retracted to its original position. Then, the windshield glass 2 with weatherstrip is removed from the side slot of the extrusion port. After that, the windshield glass 2 with a weather strip is moved by the glass take-out device 95 to the pair of glass receiving arms 10 of the glass carry-out receiving rack device 103.
1 is placed on top. According to this embodiment, FIG. 22 (B2) (C2)
The windshield glass with a weather strip schematically shown in FIG. By deforming the orifices of the fixed die and the movable die, the one schematically shown in (B2) and (C2) of FIG. 23 can be manufactured.

[0056]

As described above, according to the present invention, extrusion molding is performed while changing the outer shell shape of the extrusion molding port by appropriately moving the movable die provided in the die device.
At the same time as extruding a weatherstrip with a different cross-sectional shape on the peripheral edge of the windshield glass and at the same time integrating the weatherstrip on the peripheral edge of the windshield glass, a weatherstrip with a different cross-sectional shape depending on the location can be used. Even when the weather strip is attached, the work of fitting the weather strip into the peripheral edge of the windshield glass can be easily performed, and the weather strip can be accurately performed without misalignment. Can be improved. Further, since the movable die is provided with a wide orifice and the replenishment path communicating therewith is provided, a weather strip having a groove depending on the location and having no groove depending on the location can be integrally formed along the peripheral edge of the windshield glass. .
