Further, since the lip 84 is linearly projected (see FIG. 9), the so-called pocket of the rain garter G is shallow, and the rainwater discharged by the wiper 82 overflows from the rain garter G and the side of the vehicle. May flow to the side.

[0007]

SUMMARY OF THE INVENTION In consideration of the above facts, an object of the present invention is to provide a molding and a method for manufacturing the same, which can deepen the pocket of the rain garter without generating streaks.

[0008]

The molding according to claim 1 is continuously mounted in the gap between the peripheral portion of the windshield of the automobile and the window frame of the body from the left and right front pillar portions to the roof portion. In the molding, between the leg portion that is inserted into the gap, the head portion that extends from the upper end of the leg portion and covers the opening of the gap, and the lower surface of the head portion that projects from the side surface of the leg portion of the windshield. A glass lip that holds the peripheral edge portion, a panel lip that protrudes from the side surface of the leg portion and is elastically abutted and locked to the window frame of the body, and covers the upper surface of the windshield from the top surface of the head. And a groove lip curved and extended toward the windshield.

According to a second aspect of the present invention, there is provided a method for manufacturing a molding, in which a molding die of an extrusion molding device is expanded / contracted to continuously extrude moldings having partially different cross-sectional shapes, and the molding is performed in the mold. It is characterized by including a step of inserting into a sizing in which a design type hole different from the hole is formed, and a step of cooling the molding which has passed through the sizing.

[0010]

The molding according to claim 1 is continuously and integrally formed so as to cover the entire circumference of the windshield, and the legs of the molding are inserted into the gap between the peripheral portion of the windshield and the window frame of the body. The head covers the gap and the glass lip holds the edge of the windshield.
Further, the panel lip is elastically abutted and locked on the window frame of the body.

On the top surface of the head of this molding, a groove lip is curvedly extended toward the windshield so as to cover the upper surface of the windshield, and constitutes a rain garter. In this way, by bending the groove lip toward the windshield, a so-called deep rain garter can be configured, so that the rainwater taken off by the wiper overflows from the rain garter and flows into the side of the vehicle. Never.

In the molding method of the second aspect of the present invention, the molding is continuously extruded through the mold cavity of the molding die of the extrusion molding device. The molding expands somewhat at higher temperatures than the mold cavity of the molding die. When the molding in the high temperature state is inserted into the sizing in which a design mold hole different from the mold hole is formed, the molding is shaped into a molding suitable for the design mold hole. Here, for example, if the sizing die hole corresponding to the groove lip is curved and shaped by pressing the upper surface of the groove lip, the streak of the groove lip caused by expanding and contracting the die hole of the molding die can be eliminated. You can also deepen the rain garter's bosom. The molding thus shaped is cooled and becomes a finished product.

In addition, the length is fixed from the lower part of the front pillar part 30 to the upper part of the front pillar part 30 by (L2), and further,
The extension length is gradually shortened from the upper portion of the front pillar portion 30 to the corner portion (L3) with the roof portion 32, and disappears at the roof portion 32 (L4).

The groove lip 24 constitutes a so-called rain garter G, but unlike the linear groove lip 84 shown in FIG. 10, the groove lip 24 is curved to deepen the pocket of the rain garter G. . For this reason, the rainwater on the windshield 12 that has been removed by the wiper overflows the rain garter G and does not flow into the side of the vehicle. Further, in the roof portion 32, as shown in FIGS. 1 and 3, the groove lip 24 is eliminated, so that the aerodynamic characteristics during traveling of the vehicle are improved and no wind noise is generated.

On the other hand, from the lower surface of the head portion 16, a leg portion 18 is inserted which is inserted into a gap between the peripheral edge portion of the windshield 12 and the window frame 14 of the body. On the lower end of the leg portion 18, a glass lip 20 is provided so as to project obliquely upward. A step portion 20A is formed at the tip of the glass lip 20, and the peripheral portion of the windshield 12 is held between the step portion 20A and the lower surface of the head portion 16. Further, a panel lip 22 is provided so as to project from the leg portion 18 toward the window frame 14 side, and is abutted and locked to the upright surface 14B of the window frame 14. Further, a metal cord 23 is incorporated in the leg portion 18 in the lengthwise direction, so that the molding 10 can be curved according to the shape of the window frame 14.

The molding 10, which is composed of the leg portion 18, the head portion 16, the glass lip 20, the panel lip 22, and the groove lip 24, is integrally molded in multiple colors, and as shown in FIG. The length is set to cover the entire circumference of 14.

Here, the molding 1 according to the present embodiment.
A manufacturing method of 0 will be described. As shown in FIG. 5, a plurality of ducts 42 are connected to the extrusion head 34 of the extrusion molding device, and a resin material forming each part of the molding 10 is supplied. In this extrusion head 34,
A passage (not shown) communicating with the molding die 36 is provided,
The high temperature resin material supplied from the duct 42 is extruded from the molding die 36.

As shown in FIG. 6, the molding die 36 is provided with a die hole 28 having substantially the same design shape as the molding 10. The groove lip opening 44 of the mold hole 28 is set so as to linearly mold the groove lip 24 of the molding 10.

A shutter 38 is provided in the groove lip opening 44 to cover the opening area and expand or contract. An opening window 46 is provided at the tip of the shutter 38, and when the groove lip opening 44 is blocked, the mold hole 28 is formed.
The pressing force of the resin material extruded from is kept constant. The drive device 4 is provided at the rear end of the shutter 38.

In this way, by expanding and contracting the groove lip opening 44 of the mold hole 28 formed in the molding die 36, the groove lip 24 is gradually extended from the lower portion of the front pillar portion 30 to the corner portion (L3) with the roof portion 32. The changing molding 10 is continuously and integrally molded. Note that, as shown in FIG.
The drive timing of the molding 1 is arranged on the downstream side of the extrusion head 34 and extruded from the molding die 36.
The rotary encoder 52 detects the number of rotations of the conveyor 50 that pulls out 0, and based on this detection data, the control device 54
Determines the gradually changing portion of the molding 10 and drives the driving device 48.

On the other hand, the molding 10 extruded from the molding die 36 and expanded to some extent at a high temperature, as shown in FIG.
The shape of the groove lip opening 62 for molding the groove lip 24 is
The groove 44 is inserted into a sizing 56 which is different from the groove lip opening 44 (see FIG. 6) of the mold hole 28.

A mold hole 60 formed in the sizing 56
The molding 10 has the same shape as the mold hole 28 on the insertion side and is widened as a whole, and is slightly expanded at high temperature.
Is easy to insert. On the other hand, the mold cavity 60 on the extrusion surface side is expanded and contracted to the design size of the molding 10,
The groove lip opening 62 is curved toward the inner lip opening 64 of the head.

Therefore, the groove lip 24 of the molding 10 that has passed through the sizing 56 having different mold holes formed on both sides is gradually pressed by the upper surface and is gradually shaped, and the streak 40 generated by the contact with the shutter 38 disappears. (See Figure 10). Further, by curving the groove lip 24, the depth of the rain garter G can be deepened.

Finally, it is cooled in the water tank 58 (see FIG. 5), and the molding 10 of the designed size is obtained.

According to European safety regulations, the groove lip 24
The tip must have a certain curvature, but (R
The lower end of the groove lip should not touch the circumferential surface of 50) and the groove lip 24 is curved, so that this safety rule can be easily cleared and restrictions on the design side are reduced.

Further, in order to improve the adhesion between the respective portions of the molding 10 to the windshield and the body, as an example, the inner lip 16A of the head 16, the leg portion 18, the groove lip 24, and the glass lip 20 are shored. The outer lip 16B of the head 16, the panel lip 22, and the lower surface of the inner lip 16A are made of vinyl chloride having a hardness of 90, and the lower surface has a Shore hardness of 70.
It is preferable to mold with Akrin.
