Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a window molding attached to a fixed window such as a rear window of a vehicle, and a manufacturing method and a manufacturing apparatus therefor.
[0002]
[Prior art]
As a window molding attached to a fixed window such as a rear window of a vehicle, there is one in which a water collecting groove is formed in an upper portion and a cover portion is formed in a lower portion.
[0003]
FIG. 9 is a perspective view showing a conventional window molding disclosed in, for example, Japanese Patent Laid-Open No. 4-56627. In FIG. 9, reference numeral 1 denotes a vehicle window, which is formed by assembling a vehicle body panel 5 with a window assembly in which a window molding 3 is attached to the outer peripheral edge of a window plate 2 such as glass.
[0004]
In the window molding 3, the groove forming lip 12a extends from the vehicle interior side to the side flange side of the vehicle body panel in the upper portion 3u and the side portion 3s from the main body portion 11 attached to the window plate 2, thereby forming a water collecting groove. In 3l, the cover lip 12b extends from the vehicle exterior side to the vehicle body panel 5 to cover the gap between the window plate 2 and the vehicle body panel 5.
[0005]
In the above configuration, since the water collecting groove is formed by the groove forming lip 12a in the upper portion 3u and the side portion 3s, the water droplets flowing down the vehicle body panel 5 are collected in the water collecting groove and flow down to the window plate 2. The flow is prevented and the visibility is prevented. In the lower portion 3l, the cover lip 12b covers the gap 15 between the window plate 2 and the vehicle body panel 5 and enhances the decorativeness.
[0006]
In the conventional window molding 3, an extruded material having a groove forming lip 12a and a cover lip 12b having the same cross-sectional shape is formed over the entire length by resin extrusion, and then the upper portion 3u and the side portion 3s have groove forming lips. 12a was cut off, and the lower part 3l was manufactured by cutting off the cover lip 12b.
[0007]
As described above, the conventional window molding 3 is formed as a lip having a different shape from the groove-forming lip 12a and the cover lip 12b, and is formed by cutting out different portions, so that the cut is exposed near the lower corner portion. As a result, the appearance is impaired, the decorativeness is impaired, the sealing property is lowered, the manufacturing process is complicated, and the material loss is large.
[0008]
[Problems to be solved by the invention]
An object of the present invention is to obtain a window molding that has a continuous excellent appearance with a groove-forming lip and a cover lip, is excellent in decoration and sealing properties, and is easy to manufacture.
[0009]
Another object of the present invention is to obtain a method and an apparatus for efficiently manufacturing the window molding as described above by a simple apparatus and operation.

[0011]
The window molding of the present invention is a molding that is attached to the outer peripheral edge of a window plate of a vehicle window such as a rear window, particularly a rear window, and is made of a resin extrusion molding material. This window molding is attached to the outer peripheral edge of the window plate to constitute a window assembly, and is used to construct a vehicle window by assembling it into a window opening of a vehicle body panel.
[0012]
In the window molding of the present invention, a main body portion made of a long body that engages with the outer peripheral edge of a window plate and a synthetic resin lip protruding from the main body portion toward the vehicle body panel along the longitudinal direction are integrally formed by extrusion molding. It consists of the extrusion molding material of the formed resin. The main body portion is formed continuously and integrally so as to have a predetermined cross-sectional shape through the upper portion, both side portions, and the lower portion, and is configured to engage with the outer peripheral edge of the window plate. As the engagement structure, a structure in which a sandwiching portion is formed in the main body portion and the outer peripheral edge of the window plate is sandwiched from both the front and back sides is preferable, but other structures can be adopted for engaging the outer peripheral edge of the window plate.
[0013]
  The lip is formed integrally with the main body so as to protrude from the main body toward the body panel side, that is, the side opposite to the window plate, and the position of the lip is determined by extrusion so that the protruding position differs from the main body. The groove lip that protrudes from different positions of the main body and the cover lip are formed in different positions.With a continuously changing lip whose protruding position and shape change continuouslyIt is formed to be continuous.
[0014]
  In other words, the lip extends from the inner side of the main body to the side flange of the vehicle body panel to form a water collecting groove at the upper part, and the lower part extends from the outer side of the vehicle panel to the outer surface of the vehicle body panel. Forming a cover lip that covers the gap between the window panel and the vehicle body panelIn the region where the upper part is from the upper corner side to the lower corner side of the lower part, the groove forming lip and the cover lip are continuous by extending from different positions of the main body part to the side flange side of the vehicle body panel. Thus, a continuously changing lip whose protruding position and shape continuously change is formed.
[0015]
The side part is preferably a groove-forming lip like the upper part. In this case, the protruding position changes near the lower corner part and the lower part changes to a cover lip, but in some cases it protrudes near the upper corner part. The position may be changed to form a cover lip on the side portion.
[0016]
The window molding is made of an extruded product of resin (including rubber), but may be combined with other materials. In particular, if the core part is integrated with a stretch-resistant core material in the longitudinal direction, it is excellent in dimensional stability during use, and the amount of delivery is detected while preventing longitudinal stretching during production. It is preferable because the lip can be formed accurately by accurately controlling the operation of the movable type. As such a core material, a hard material such as a metal profile can be used. In this case, the decorative material can be formed by exposing the core material to the surface.
[0017]
The main body portion is preferably formed to have the same cross-sectional shape throughout the entire length, but in some cases, shaping may be performed in a subsequent process so that the cross-sectional shape changes in part. Similarly, the groove-forming lip and the cover lip can be formed in substantially the same cross-sectional shape, but the cross-sectional shape can be changed in a subsequent shaping step. In this case, in the shaping step, it is preferable to shape the tip of the groove forming lip at least in the upper part so as to curve outward.
[0018]
The window molding as described above includes a fixed mold having a fixed orifice for extruding the main body section, a movable mold having a movable orifice for extruding the lip and integrating with the main body section, and a movable mold to move the lip to the main body. It can manufacture with the extrusion die provided with the drive device integrated in the predetermined position of a part.
[0019]
  In the driving device, the lip extends from the vehicle interior side to the side flange side of the vehicle body panel at the upper portion to form a groove forming lip, and the lower portion extends from the vehicle exterior to the outer surface side of the vehicle body panel to cover the cover lip. FormationIn the region where the upper part is from the upper corner side to the lower corner side of the lower part, the groove forming lip and the cover lip are continuous by extending from different positions of the main body part to the side flange side of the vehicle body panel. To form a continuously changing lip whose protruding position and shape change continuouslyThus, the movable mold can be moved. In this case, it is preferable to have a control device that detects the feed amount of the core material into the extrusion mold or the extrusion amount and movement amount of the extrusion molding material as a substitute value of the extrusion length, and controls the driving device based on this detection. .
[0020]
The movable type is configured to be movable adjacent to the fixed type, and is preferably configured to rotate around the resin connection port for lip formation. In this case, the drive device rotates the movable type. However, the movable type may be configured to reciprocate linearly, for example.
[0021]
When the core material is integrated with the main body, a core material supply device that supplies a stretch-resistant core material to the fixed orifice of the fixed mold is provided upstream of the extrusion mold. In order to deform the extruded lip, a shaping device is provided downstream of the extrusion mold.
[0022]
  In order to manufacture a window molding by the manufacturing apparatus as described above, a body having a predetermined cross-sectional shape is extruded from a fixed orifice provided in a fixed mold of an extrusion mold, and a movable orifice provided in a movable mold. A lip having a predetermined cross-sectional shape is extruded from the upper portion, and the position of the lip with respect to the main body portion is extended from the vehicle inner side of the main body portion to the side flange side of the vehicle body panel by the driving device to form a groove-forming lip. Then, it extends from the outside of the car to the outer surface of the car body panel to form a cover lipIn the region where the upper part is from the upper corner side to the lower corner side of the lower part, the groove forming lip and the cover lip are continuous by extending from different positions of the main body part to the side flange side of the vehicle body panel. To form a continuously changing lip whose protruding position and shape change continuouslyThe window mold is manufactured by moving the movable mold so that the extruded lip is welded and integrated with the main body.
[0023]
When a linear core material having stretch resistance is integrated, the core material is continuously supplied from the core material supply device and the main body portion is extruded. When a metal profile is used as the core material, the profile is supplied to the fixed mold to form the main body, and the lip is integrated therewith. When the movable type is a rotary type, the lip is integrated by rotating the movable orifice so as to move by the driving device.
[0024]
The resin that forms the main body and the resin that forms the lip may be the same or different. However, in the case where they are different, it is preferable to use a resin having compatibility with different physical properties such as hardness and elastic modulus. In general, the main body is preferably a semi-rigid resin, for example a semi-rigid PVC resin, in order to increase the mounting stability, and the lip is soft in order to increase the shock-absorbing property, sealing property, and prevention of damage to the body panel. A resin having high clip resistance, for example, a soft PVC resin or a TPE resin (thermoplastic elastomer resin) is preferable.
[0025]
In order to deform the lip, after the lip is extruded, it is shaped by the shaping device so that the tip of the upper part is curved toward the outside of the vehicle. Both the main body and the lip may be shaped so that the cross-sectional shape changes partially by cutting or the like.
[0026]
【The invention's effect】
  In the window molding of the present invention, the lip protruding from the main body portion is not in the upper portion.It extends from the vehicle interior side to the side flange side of the vehicle body panel to form a groove-forming lip, and the lower portion extends from the vehicle exterior side to the outer surface side of the vehicle body panel to form a cover lip. The projecting position and shape continuously change so that the groove forming lip and the cover lip are continuous by extending from a different position of the main body part to the side flange side of the vehicle body panel at a portion where these are continuous in the region reaching the lower corner side. Formed to be a continuously changing lipAs it is extruded integrally with the main body,Even when attached to the window plate of the window assembly assembled in the window assembly insertion recess formed in the window opening of the vehicle body panel,In the upper part, a water collecting groove can be formed to prevent water droplets on the vehicle body panel (roof panel) from flowing to the window plate, and the decorativeness can be enhanced by covering the gap in the lower part. The cover lip has a continuously excellent appearance, and it is possible to obtain a window molding that is excellent in decoration and sealing properties and easy to manufacture.
[0027]
When the main body has a stretch-resistant core material, the dimensional stability during use is increased, and the amount of lip protruding is accurately controlled by measuring the supply amount during manufacturing and accurately controlling the operation of the movable mold. It is easy to form, and a molding in which the lip accurately changes at a predetermined position can be obtained. A groove-forming lip and a cover lip having substantially the same cross-sectional shape can be easily manufactured by simply changing the protruding position of the lip from the main body. In addition, when the tip of the groove-forming lip is curved so as to be curved toward the outer surface, the groove formation and the mounting operation of the vehicle body panel at a predetermined position are easy, and a water collecting groove having a predetermined shape can be formed. .
[0028]
In the manufacturing method of the window molding of the present invention, the main body is extruded from the extrusion shaping fixed mold, and the movable mold can be moved by the driving device while pushing the lip from the movable mold to change the projecting position of the lip to be integrated. The above window molding in which the protruding position of the lip continuously changes can be easily manufactured by a simple device and operation.
[0029]
In this case, by integrating the stretch-resistant core material and extruding the main body, the feed amount can be measured to accurately control the operation of the movable mold and accurately form the protruding position of the lip. Sometimes a molding with high dimensional stability can be produced. When a metal profile is used as the core material, the metal profile can be formed from the metal profile to obtain a highly decorative molding.
[0030]
In the case where a resin having compatibility with the resin forming the main body and the resin forming the lip is used, since the two are welded together, a molding having high adhesion and high shape stability can be manufactured.
When shaping is performed after the lip is extruded, a molding whose tip is curved in the upper portion can be easily manufactured by shaping.
[0031]
Since the manufacturing apparatus of the present invention includes the extrusion mold having the fixed mold and the movable mold and the driving apparatus, the window molding can be efficiently manufactured with a simple structure and operation.
[0032]
When a rotary type is used as the movable type, it can be rotated around the resin flow path for lip formation, and therefore, resin leakage at the movable type sliding portion is less than in the case of the linear reciprocating type. Thus, the movable mold can be moved smoothly to facilitate manufacturing.
[0033]
In the case where the core material supply device is provided, a stretch resistant core material can be supplied to the fixed orifice and integrated, and in this case, the manufacturing process can be controlled by the supply amount of the core material.
[0034]

Although the end portion (joining portion) 3e in the longitudinal direction is arranged at 3l, an end portion 3e ′ may be provided in the upper portion 3u instead of this position. One window molding 3 is preferably used through the upper part 3u, the side part 3s, and the lower part 3l. However, the window molding 3 may be partially cut off at a corner part, for example.
[0037]
The window molding 3 is made of an extruded material of resin, and a main body portion 11 that engages so that the outer peripheral edge of the window plate 2 is sandwiched from both the front and back sides and a lip 12 that extends from the main body portion 11 toward the vehicle body panel 5 side are integrated. And is integrally and continuously formed by extrusion through the upper portion 3u, the side portion 3s, and the lower portion 3l.
[0038]
The main body 11 is embedded with a deformable elongated core material 14 which is stretch-resistant in the longitudinal direction in a fixed position of the main body 11 over the entire length, and is substantially U-shaped in the same cross section through the upper portion 3u, the side portion 3s, and the lower portion 3l. The guide plate 16 has an insertion groove 15 and a guide surface 16 into which the outer peripheral edge of the window plate 2 is inserted. A decorative strip 18 such as a metal foil or a resin tape having a different color from that of the main body 11 can be attached to the outer surface of the main body 11. Examples of the core material 11 include a metal wire, a metal tape, and a glass fiber yarn whose surface is coated with an adhesive. Further, such a core material is preferably provided at or near a neutral line of bending when the window molding is bent and attached later.
[0039]
  The lip 12 is integrally formed with the main body portion 11 so as to protrude from the arcuate surface of the main body portion 11 toward the vehicle body panel 5 side, that is, the side opposite to the window plate 2, and the protruding position of the lip 12 is The groove lip 12a and the cover lip 12b projecting from different positions are formed by moving the positions by extrusion so as to be different.By the continuously changing lip 12c whose protruding position and shape change continuouslyIt is formed to be continuous.
[0040]
  In other words, the lip 12 has a groove-forming lip 12a at the upper portion 3u and the side portion 3s that extends from the position on the inner side of the arcuate surface 17 of the main body 11 toward the side flange 5a of the vehicle body panel 5 to form the water collecting groove 19.

[0041]
The main body 11 is formed in the same cross-sectional shape over the entire length, but the cross-sectional shape may be changed depending on circumstances. The basic cross-sectional shape of the lip 12 is substantially the same. However, as shown by a chain line 12a 'in the free state, the groove forming lip 12a of the upper portion 3u and the side portion 3s has its tip directed toward the outside of the vehicle. It is deformed to be curved.
[0042]
The window molding is formed in an annular shape by joining the end portions 3e in advance, and the annular window molding 3 is attached to the outer peripheral edge of the window plate 2 on which the opaque print layer 9 is previously formed and the dam rubber 10 is fixed. An assembly 4 is formed. In this case, it is preferable to apply an adhesive to the insertion groove 15 of the window molding 3 and insert and fix the outer peripheral edge of the window plate 2, but this is not always necessary. At this time, the opening-shaped guide surface 16 facilitates the insertion and engagement of the window plate 2 and the window plate 2.
[0043]
With the window assembly 4 thus manufactured, the liquid adhesive 7 is continuously discharged in a string shape between the dam rubber 10 and the main body 11 of the window molding 3, the window opening 6 of the vehicle body panel 5 is opened. The vehicle is fitted into the window assembly insertion recess 8 so as to be shielded, and the adhesive 7 interposed between the window assembly 4 and the side flange 5a and the bottom flange 5b of the vehicle body panel 5 is cured and fixed. The window 1 for manufacture is manufactured.

[0045]
  In the window molding 3 described above, the lip 12 protruding from the main body portion 11 becomes a groove forming lip 12a in the upper portion 3u and the side portion 3s,In the vicinity of the lower corner 3cl, a continuously changing lip 12c is formed.Since the lower part 3l becomes a cover lip 12b and is integrally formed with the main body 11 so that these continuously change smoothly, the water collecting groove 19 is formed in the upper part 3u and the side part 3s. Water droplets on the vehicle body panel (roof panel) 5 can be prevented from flowing to the window plate 2 and disappear smoothly before the water collecting groove 19 reaches the lower portion 31. The lower portion 3l covers the gap 20 and is decorative. Can be increased. In this case, the groove forming lip 12a and the cover lip 12bContinuously changing lip 12cIt is possible to obtain a window molding that has a continuously excellent appearance, is excellent in decorativeness and sealing properties, and is easy to manufacture.
[0046]
  In addition, since the main body 11 has the stretch-resistant core material 14, the dimensional stability during use is enhanced, and the supply amount of the core material is measured at the time of manufacture to accurately control the operation of the movable type, thereby It is easy to accurately form the protruding position, and the molding 3 in which the lip 12 changes at a predetermined position is obtained. Groove forming lip 12a and cover lip 12bAnd continuously changing lip 12cAre formed in substantially the same cross-sectional shape, and can be easily manufactured only by changing the protruding position of the lip 12. Moreover, since the front-end | tip part of the groove | channel formation lip | rip 12a is shaped so that it may curve toward the vehicle outer side, groove | channel formation is easy and the water collecting groove | channel 19 of a predetermined shape can be formed.
[0047]

As shown in FIG. 5, the manufacturing method of the window molding 3 continuously feeds the core material 14 from the uncoiler 21 through the pinch roll 22, and the amount of delivery is detected by the detection device 23 of a delivery amount detection sensor such as a rotary encoder. It supplies to the extrusion mold 24, detecting. When integrating the decorative strip 18, the decorative strip 18 is fed from the uncoiler 21 a and supplied to the extrusion mold 25. The detection signal 42 of the detection device 23 is input to the control device 31. Instead of detecting the delivery amount of the core material 14 as in this embodiment, the detection is performed by directly detecting the extrusion amount of the extrusion molding material 41 described later at the position of the extrusion mold 24 or downstream of the take-up machine 28. A device 23a or 23b may be provided.
[0054]
In the extrusion mold 24, a relatively hard resin, for example, a semi-rigid polyvinyl chloride resin, is supplied from the resin supply path 25a as the resin 42a for forming the main body portion 11, and the fixed orifice 33a is passed through the resin flow path 32a of the fixed mold 24a. The body part 11 is formed by extrusion. Further, as the resin 42b for forming the lip 12 from the resin supply path 25b, an elastomer resin that is rich in elasticity, has high clip resistance, is relatively soft, and is compatible with the resin, and the resin flow path 32b of the fixed mold 24a and The lip 12 is formed by extrusion from the movable orifice 33b of the movable mold 24b through the resin flow path 32c of the movable mold 24b, and is fused and integrated with the main body portion 11.

  When the extrusion molding material 41 advances and the next lower corner portion 3cl is molded, the drive signal 43 is again sent from the control device 31 to the drive device 40, and the drive device 40 is rotated to move the movable die 24b. The side part 3s and the upper part 3u are molded by rotating in the R direction. In this way, the extruded material 41 in which the molding 3 shown in FIG. 4 is continuous is formed. In addition, the broken line in FIG.12cuThe lip 12 changes position near the upper part on both sidesContinuously changing lip 12c is formedAn example is shown.
[0059]
The extrusion molding material 41 thus molded is cooled and cured by the cooling device 27, taken by the take-up machine 28, and then cut by the cutting machine 29 to manufacture the window molding 3. The cutting position is 3e shown in FIGS. 1 and 4, that is, a position corresponding to the middle part of the lower part 3l, but may be a position corresponding to 3e ', that is, a middle part of the upper part 3u depending on circumstances.
[0060]
Cutting of the extrusion molding material 41 is performed by inputting a cutting signal 44 from the control device 31 to the cutting machine 29 based on the detection signal 42 of the detection device 23 (or 23a, 23b). In this case, the movable die 24b is calculated from the distance of the cutting machine 29 and the extrusion speed of the core material 14 or the extrusion molding material 41 to calculate the time point when the scheduled cutting position reaches the position of the cutting blade of the cutting machine 29, and the cutting signal 44 is output. When the position and speed of the extrusion molding material 41 are detected by the detection device 23b, the cutting time point is calculated from the distance between the detection device 23b and the cutting machine 29 and the speed of the extrusion molding material 41. As the detection devices 23a and 23b, an infrared sensor or the like that detects the position of the lip 11 is used. As the cutting machine 29, a traveling cutting machine that travels and cuts at the same speed as the extrusion molding material 41 is used.
