Description

  The present invention relates to a method for manufacturing a window assembly to be mounted on a window frame portion of an automobile or the like.

  In general, a window assembly attached to a window frame portion of an automobile is provided with a long shielding member for closing a gap between the window plate and the window frame portion along the outer peripheral edge of the window plate. The window assembly is bonded and fixed to the window frame portion by interposing and curing a paste-like sealant between the back surface of the outer peripheral edge of the window plate and the window frame portion, and the window assembly and the window frame portion The space between them is sealed. In addition, since it usually takes two days and nights (for example, about 48 hours) until the paste-like sealant is completely cured, when the window assembly is attached to the window frame portion, By engaging the fixing tool provided at a predetermined location with the engagement hole formed in the window frame, and temporarily fixing the window assembly with the window frame positioned, the sealant is cured. In the meantime, the window assembly is prevented from being displaced.

Thus, when manufacturing the window assembly which provided the shielding member and the fixing tool in the window board, as described in patent document 1 (patent 2554537), for example, the shielding member in a window board The adhesive is discontinuously separated and applied to the planned adhesion area of the holding part and the planned adhesion area of the holding part for holding the fixture, and then the window plate and the fixture to which the adhesive is applied are placed in the injection mold. The shielding member and the holding part are made of the material by setting the resin material injected into the cavity for molding the shielding member into the cavity for molding the holding part through the material flow cavity. There is one in which the material flow connecting portion is removed after the shielding member and the holding portion are bonded and fixed to the window plate after being molded into a shape connected by the flow connecting portion.
Japanese Patent No. 2554537 (2nd page, etc.)

  However, in the manufacturing method of Patent Document 1, since the shielding member and the holding portion are formed into a shape connected by the material flow connecting portion, it is necessary to remove the material flow connecting portion after forming. In addition, when removing the material flow connecting portion, if the material flow connecting portion is to be cut with a knife such as a knife (or the portion to be separated is cut with a blade), the window plate is used with the blade. There is a risk of scratching.

  The present invention has been made in consideration of these circumstances. Therefore, an object of the present invention is to provide a method for manufacturing a window assembly capable of improving manufacturing efficiency and manufacturing quality when manufacturing the window assembly. Is to provide.

  In order to achieve the above-mentioned object, a method for manufacturing a window assembly according to claim 1 is configured such that a gap between the window plate and the window frame portion is blocked by a window plate that can be attached to a predetermined window frame portion. A long shielding member made of a polymer material integrally formed along an outer peripheral edge of at least a part of the window plate, and a window plate for positioning the window plate with respect to the window frame portion. A method of manufacturing a window assembly provided with a positioning member fixed on the back surface of an outer peripheral edge away from the shielding member toward the center of the surface of the window plate, and bonding the shielding member of the window plate An adhesive application step for applying an adhesive to a predetermined area, an adhesion planned area of the positioning member and a holding portion for holding the positioning member, a cavity for forming the shielding member, and a cavity for forming the holding portion Are provided independently and injected into each cavity. By setting the window plate coated with the adhesive and the positioning member in an injection mold provided with a sheet, and injecting a predetermined polymer material into each cavity from each injection gate, The shielding member and the holding portion are molded, and a molding step of bonding and fixing the shielding member and the holding portion to the window plate via the adhesive is performed.

  In this method, since the injection molding die in which the cavity for molding the shielding member and the cavity for molding the holding part are provided independently and each cavity is provided with an injection gate is used, the shielding member and the holding part are molded independently. can do. For this reason, compared with the conventional case where the shielding member and the holding portion are connected to each other by the material flow connecting portion, the work for removing the material flow connecting portion is not required. Manufacturing efficiency can be improved by simplifying the manufacturing process. Moreover, it is possible to prevent problems such as finger injury when the window plate is scratched or removed manually due to the removal work of the material flow connection part, and to improve manufacturing quality and work safety. Can do.

By the way, when the shielding member and the holding portion are molded in a state where the positioning member is set in the molding die, there are many restrictions on the cavity shape of the molding die and the shape of the positioning member.
Therefore, as described in claim 2, after the shielding member and the holding portion are formed of a predetermined polymer material, a positioning member prepared separately in advance may be attached to the holding portion. This eliminates the need to set a positioning member in the mold during molding, thereby reducing restrictions on the cavity shape of the mold and the shape of the positioning member, simplifying the configuration of the mold and positioning member. The degree of design freedom can also be increased.

  Further, as in claim 3, the shielding member and the positioning member may be simultaneously injection-molded with a predetermined polymer material. In this way, the positioning member can be molded from the polymer material for molding the shielding member, the number of parts can be reduced, and the labor for attaching the positioning member is not required.

  Further, as in claim 4, in the adhesive application step, the range of application of the adhesive applied to the positioning member and the planned bonding area of the holding portion of the window plate is determined from the outer shape of the end surface on the bonding side of the positioning member. It is also preferable to make it wider. In this way, the positioning member and the entire end surface of the holding portion can be securely adhered to the adhesive layer even if some misalignment or variation occurs in the application range of the adhesive layer. The holding portion can be securely bonded to the window plate.

  Further, the window plate may be moved by fixing the position of the coating head for applying the adhesive to the window plate in the adhesive coating step. In this way, compared to the case where the adhesive is applied by moving the coating head, the configuration of the adhesive coating device can be simplified and the cost can be reduced. The window plate can be smoothly transferred to the next step (for example, heating / drying step) using the system such as the robot that has moved the window plate to the next.

  In addition, in the adhesive application step, the adhesive layer of both the planned adhesion regions in the planned adhesion region of the shielding member of the window plate and the planned adhesion region of the positioning member and / or the holding portion in the adhesive application step. The adhesive may be continuously applied so as to be continuous through a predetermined adhesive continuous region. In this way, it is not necessary to divide the work of applying the adhesive on the window plate into a plurality of times, the adhesive application work can be performed efficiently, and the adhesive is uniformly applied to each bonding scheduled area. In addition, the thickness and drying time of the adhesive layer in each of the planned adhesion regions can be made substantially the same, and stable adhesive strength can be obtained.

  In the inventions according to the seventh to ninth aspects, the adhesive coating process of the first to third aspects is omitted, respectively, and a window plate in which an adhesive is applied in advance to each bonding planned area is obtained and the window is obtained. An assembly is manufactured. Even if it does in this way, the effect similar to Claims 1-3 can be acquired, respectively.

  Furthermore, as described in claim 10, when performing the forming step, at least a portion of the window plate to which the adhesive is applied may be heated in advance. If it does in this way, the solvent of the adhesive agent apply | coated to the window board can be volatilized stably at the time of injection | pouring of a polymer material, and adhesive strength can be stabilized.

  By the way, the injection mold used for manufacturing the window assembly has a cavity for molding the holding portion and a cavity for molding the positioning member (hereinafter referred to as a cavity for molding a long shielding member). These are collectively referred to as “specific cavities”), and when the polymer material is injected and filled in each cavity during the molding process, the pressure of the polymer material in the specific cavity becomes too high, resulting in a long A large pressure is applied to the window plate over time, and the window plate may crack or crack.

  As a countermeasure against this, the pressure of the polymer material injected and filled in a specific cavity (a cavity for molding the holding portion or a cavity for molding the positioning member) in the molding process as in claim 11 is an allowable limit. It is preferable to limit the pressure by means of a pressure increase limiting means so as not to exceed the value. In this way, the pressure of the polymer material in the specific cavity can be appropriately increased while limiting the pressure of the polymer material in the specific cavity so that it does not exceed the allowable limit value by the pressure increase limiting means. While securing the adhesive strength and formability between the holding part and positioning member molded with polymer material in the cavity and the window plate, it prevents excessive pressure from being applied to the window plate and prevents cracks and cracks in the window plate. Occurrence can be prevented.

  As a specific example of the pressure increase limiting means, as in claim 12, a specific cavity is provided with a discharge cavity communicating with the specific cavity via a discharge path so that the pressure of the polymer material in the specific cavity does not exceed the allowable limit value. A part of the inner polymer material may be discharged to the discharge cavity through the discharge path. In this configuration, even if an excessive amount of polymer material is supplied into a specific cavity, the excess polymer material can be pushed out of the specific cavity and discharged into the discharge cavity, and the pressure of the polymer material in the specific cavity is within the allowable limit. It can be restricted so as not to exceed the value. In addition, the polymer material injected first has a lot of heat taken away by the flow path and cavity, and starts to solidify due to temperature drop during the flow process. The solidified polymer material is identified by the subsequent polymer material. Since it is possible to extrude from the cavity, the specific cavity can be filled only with a well-melted polymer material. For this reason, it is possible to further improve the adhesive strength and formability between the holding portion and the positioning member molded with the polymer material in the specific cavity and the window plate. In addition, there is an advantage that this effect can be realized with a simple configuration in which only a discharge cavity communicating with the specific cavity is provided.

  In this case, a discharge path for discharging the polymer material into the discharge cavity may be provided on the opposite side of the injection gate in the specific cavity. In this way, the polymer material injected from the injection gate reaches the discharge path located on the opposite side of the injection gate after being filled into the specific cavity and is discharged into the discharge cavity. Without leaving an unfilled portion of the polymer material, the polymer material can be reliably filled to every corner in the specific cavity.

  In addition, when removing a portion formed by the discharge cavity after the forming step, as in claim 14, at least a part of the discharge path is narrower than the other part of the flow path. In the molding step, at least a part of the molding portion by the discharge passage that connects the molding portion by the specific cavity and the molding portion by the discharge cavity is formed into a thin shape by the narrow portion, and after the molding step The molding part by the specific cavity and the molding part by the discharge cavity may be separable by a narrow part by the narrow part. Since the slender portion can be easily torn or cut, when it is necessary to remove the slender portion, it is possible to facilitate the work of separating the molded portion (holding portion or positioning member) by the specific cavity and the molded portion by the discharge cavity.

  As another specific example of the pressure increase limiting means, as in claim 15, the pressure detecting means for detecting the pressure of the polymer material in the specific cavity and the supply path for supplying the polymer material into the specific cavity are opened and closed. Or an opening / closing valve for adjusting the opening degree, and controlling the amount of polymer material supplied into the specific cavity by controlling the closing timing or opening degree of the opening / closing valve based on the detected pressure of the pressure detecting means. Thus, the pressure of the polymer material in the specific cavity may be limited so as not to exceed the allowable limit value. In this way, the pressure of the polymer material in the specific cavity can be controlled while the actual pressure of the polymer material in the specific cavity is monitored by the pressure detection means, so the pressure of the polymer material in the specific cavity can be controlled. It can be accurately limited to the allowable limit value or less, can more reliably prevent cracks and cracks in the window plate, and improve the adhesive strength and moldability between the holding part and positioning member and the window plate. be able to.

  Alternatively, as in claim 16, the pressure detection means for detecting the pressure of the polymer material in the specific cavity, and an open / close valve for opening / closing or adjusting the opening of the discharge path for discharging the polymer material in the specific cavity, The pressure of the polymer material in the specific cavity is controlled by controlling the valve opening timing or opening degree of the on-off valve based on the detected pressure of the pressure detecting means to control the discharge amount of the polymer material from the specific cavity. You may make it restrict | limit so that an allowable limit value may not be exceeded. Even if it does in this way, the effect similar to the said Claim 15 can be acquired.

  As is clear from the above description, according to the present invention, since the work for removing the material flow connecting portion is not required, the manufacturing process of the window assembly can be simplified and the manufacturing efficiency can be improved. In addition, it is possible to prevent problems such as scratches on the window plate and injury of fingers due to the removal work of the material flow connecting portion, and it is possible to obtain an excellent effect that manufacturing quality and safety can be improved. .

  Hereinafter, six Examples 1 to 6 in which the present invention is applied to a window assembly for an automobile window will be described.

  A first embodiment of the present invention will be described with reference to FIGS. First, a schematic configuration of the rear window assembly 11 will be described with reference to FIGS. 1 to 3. The window plate 12 (rear window glass) of the window assembly 11 is formed in a shape corresponding to the window frame portion 13 (see FIG. 2) on which the window plate 12 is mounted (for example, a generally curved, generally rectangular shape). . An opaque colored layer 14 (also referred to as a “frit layer” in the case of a glass window plate) is formed on the back surface of the window plate 12 with a predetermined width along the outer peripheral edge of the window plate 12. Thus, the back side of the outer peripheral edge of the window plate 12 is not seen through from the front side of the window plate 12.

  Further, as shown in FIG. 2, a long shielding member 15 is provided on the back surface of the window plate 12 along the outer peripheral edge of the window plate 12 (the outer peripheral edge of the opaque colored layer 14). The shielding member 15 is formed by injection molding of a predetermined polymer material, and is bonded and fixed to the opaque colored layer 14 on the back surface of the window plate 12 by a first adhesive layer 31 described later. The elastically deformable lip portion 16 formed integrally with the base portion of the shielding member 15 abuts on the peripheral wall portion 17 of the window frame portion 13 so as to close the gap between the window plate 12 and the window frame portion 13. It has become.

  Further, as shown in FIG. 3, positioning fixtures 18 (positioning members) for temporarily fixing the window plate 12 in a state where the window plate 12 is positioned with respect to the window frame portion 13 are provided at a plurality of positions on the back surface of the window plate 12. It has been. The positioning fixture 18 is disposed at a position away from the shielding member 15 toward the center of the surface of the window plate 12 within the range of the opaque colored layer 14 on the back surface of the window plate 13. A disc-shaped pedestal portion 19 formed in the portion is surrounded and held by a holding portion 20. The holding portion 20 is formed by injection molding of the same polymer material as that of the shielding member 15, and is bonded and fixed to the back surface of the window plate 12 by a second adhesive layer 32 described later. The positioning fixture 18 is formed of an elastic material such as POM resin. An elastically deformable engaging portion 21 is integrally formed at the tip of the positioning fixture 18, and the window assembly 11 is attached to the window frame portion 13. The window assembly until the sealant 47 described later is cured by elastically engaging the engagement portion 21 of the positioning fixture 18 with the engagement hole 23 formed in the flange portion 22 of the window frame portion 13. 11 can be temporarily fixed while being positioned with respect to the window frame portion 13.

  Next, a method for manufacturing the window assembly 11 having the above configuration will be described with reference to FIGS. First, the window plate 12 on which the opaque colored layer 14 is previously formed in another place is prepared, and the process proceeds to the adhesive application step. As shown in FIG. 4, the adhesive application device 24 used in this adhesive application process supplies the liquid adhesive stored in the adhesive tank 25 to the application head 28 via the supply pipe 27 by the pump 26. The adhesive coating portion 29 of the coating head 28 is fixed at a position where it is brought into contact with the back surface of the window plate 12 in a state where the adhesive coating portion 29 is lightly biased toward the window plate surface side by a spring or the like (not shown). The adhesive is applied to the back surface of the window plate 12 by sliding in the direction. As shown in FIG. 4, the adhesive application portion 29 of the application head 28 may be formed of a similar material such as a brush-like member or a surface fastener, or a porous material such as sponge or felt. You may make it form.

  In this adhesive application step, as shown in FIG. 5, an adhesive is applied to the planned adhesion region (hereinafter referred to as “first adhesion planned region”) S <b> 1 of the shielding member 15 on the back surface of the window plate 12. A first adhesive layer 31 is formed, and an adhesive is applied to a bonding planned area (hereinafter referred to as “second bonding planned area”) S2 of the positioning fixture 18 and the holding unit 20 to apply a second adhesive layer. 32 is formed. In that case, an adhesive agent is continuously apply | coated so that the adhesive bond layers 31 and 32 of both adhesion plan area | regions S1 and S2 may continue through predetermined adhesive continuous area | region S3.

In this case, for example, the window plate 12 is held by a hand of an articulated robot (not shown), and the adhesive is continuously applied to the back surface of the window plate 12 as follows.
First, as shown by a solid line (i) in FIG. 5, the window plate 12 is moved so that the coating head 28 slides relatively along the first adhesion planned area S1, and the first adhesion planned area An adhesive is applied to S1.

  Then, every time the coating head 28 approaches the second planned bonding region S2, as shown by a broken line (ii) in FIG. 5, the coating head 28 moves from the first planned bonding region S1 → the adhesive continuous region S3 → second. The window plate 12 is slid so as to move relatively along the route of the planned adhesion area S2 → adhesive continuous area S3 → first adhesion expected area S1, and the adhesive is applied to the second adhesion expected area S2. To do. At that time, the application range of the adhesive applied to the second planned bonding region S2 is made wider than the outer shape of the end face on the bonding side of the base 19 and the holding part 20 of the positioning fixture 18. Similarly, it is preferable that the application range of the adhesive applied to the first planned bonding region S1 is slightly wider on the inner side than the width of the shielding member 15.

  Thereafter, as indicated by a solid line (iii) in FIG. 5, the window plate 12 is moved so that the coating head 28 moves relatively along the first planned bonding region S1, and the first bonding planned An adhesive is applied to the region S1. The movement of the window plate 12 described above can be performed by driving and controlling the robot hand with a predetermined program.

  After completion of the adhesive application process, the process proceeds to the drying process. In this drying step, the window plate 12 coated with the adhesive is put in a drying furnace or the like, and the entire window plate 12 is preferably heated. Thereby, the application part of the adhesive agent of the window board 12 is heated, and volatilization of the solvent contained in an adhesive agent is accelerated | stimulated. Note that the thickness of the adhesive layer is shown enlarged in the thickness direction for easy understanding.

  After this drying process, the process proceeds to the molding process. As shown in FIG. 6, the injection molding die 35 used in this molding process forms a shielding member molding cavity 36 for molding the shielding member 15 and a holding portion 20 that holds the pedestal portion 19 of the positioning fixture 18. A holding part forming cavity 37 is provided independently. A shielding member molding injection gate 38 is provided at one location of the shielding member molding cavity 36 or at a plurality of locations along the longitudinal direction of the cavity 36, and the holding portion molding cavity 37 has an injection for holding portion molding. A gate 39 is provided. The molten polymer material injected from the injection nozzle (not shown) of the injection molding machine is filled into the shielding member molding cavity 36 through the path of the runner 40 → the sprue 41 → the shielding member molding injection gate 38, and The holding portion molding cavity 37 is filled through a path from the runner 40 to the sprue 42 to the holding portion molding injection gate 39.

  In this molding step, as shown in FIG. 6, first, the window plate 12 coated with the adhesive and the positioning fixture 18 are set in the injection mold 35, and the injection mold 35 is closed. Thereafter, the molten polymer material is injected into the cavities 36 and 37 from the injection gates 38 and 39 and then filled, and then the polymer material is cooled and solidified or cured, as shown in FIG. The holding part 20 is formed independently, and the shielding member 15 and the holding part 20 are bonded and fixed to the opaque colored layer 14 on the back surface of the window plate 12 via the adhesive layers 31 and 32, respectively. Thereafter, the injection molding die 35 is opened, and the window assembly 11 to which the shielding member 15 and the holding portion 20 are bonded and fixed is ejected by the ejection pin 45 and removed from the injection molding die 35, whereby the window assembly 11 is manufactured. Complete. With this protrusion, the shielding member 15 and the holding portion 20 are automatically broken and separated from the sprues 41 and 42 at the portions of the injection gates 38 and 39, respectively.

  As a polymer material for molding the shielding member 15 and the holding portion 20 in this molding process, for example, a general-purpose thermoplastic resin such as ABS (acrylonitrile / butadiene / styrene), PVC (polyvinyl chloride), PP (polypropylene) or the like is used. Use it. In addition, engineering thermoplastic resins such as PA (polyamide), PC (polycarbonate), PPE (polyphenylene ether), TPO (olefin thermoplastic elastomer), SBC (styrene thermoplastic elastomer), TPVC (vinyl chloride thermoplastic) Elastomers), thermoplastic elastomers such as TPU (urethane-based thermoplastic elastomers), and liquid reactive mixed materials of polyol and isocyanate that react to produce PU (polyurethane) may be used. In consideration of the environment in which the window assembly 11 is used, a filler, a modifier or the like may be mixed in the polymer material.

  When the window assembly 11 manufactured as described above is attached to the window frame portion 13, as shown in FIGS. 2 and 3, the shielding member is within the range of the opaque colored layer 14 on the back surface of the window plate 12. A dam 46 for sealing the sealant is fixed by adhesion or the like at a position away from the surface center side of the window plate 12 from 15, and the outer periphery of the dam 46 on the inner peripheral side of the shielding member 15 on the back surface of the window plate 12. A paste-like urethane sealant 47 is discharged to the side along the outer peripheral edge. At this time, at the position of the positioning fixture 18, the sealant 47 is discharged onto the opaque colored layer 14 between the positioning fixture 18 and the shielding member 15. Thereafter, the window assembly 11 is fitted into the window frame portion 13, and a paste-like sealant 47 is interposed between the rear surface of the entire outer peripheral edge of the window plate 12 and the flange portion 22 of the window frame portion 13. By hardening the sealant 47, the window assembly 11 is adhered and fixed to the window frame portion 13, and the gap between the window assembly 11 and the window frame portion 13 is sealed. At that time, the engaging portions 21 of the positioning fixtures 18 fixed to the back surface of the window plate 12 are elastically engaged with the engaging holes 23 of the flange portion 22 of the window frame portion 13, respectively. The window assembly 11 is displaced until the sealant 47 is cured by temporarily fixing the window frame portion 13 in a state where the window frame portion 13 is positioned in both the direction parallel to the surface of the window plate 12 and the thickness direction. To prevent that.

  In the first embodiment described above, in the molding process when the window assembly 11 is manufactured, the shielding member molding cavity 36 and the holding part molding cavity 37 are provided independently, and the cavities 36 and 37 are respectively provided. Since the injection molding die 35 provided with the submarine gate type (or tunnel gate type) injection gates 38 and 39 is used, the shielding member 15 and the holding portion 20 are independently molded. When the mold is removed, the injection gates 38 and 39 are automatically broken. Therefore, compared with the conventional case where the shielding member 15 and the holding part 20 are formed into a shape in which the shielding member 15 and the holding part 20 are connected by the material flow connection part, the work for removing the material flow connection part becomes unnecessary. The manufacturing process of 11 can be simplified and manufacturing efficiency can be improved. In addition, it is possible to prevent problems such as damage to the window plate 12 and injury of fingers due to the removal work of the material flow connecting portion, and it is possible to improve manufacturing quality and work safety.

  Further, in the first embodiment, in the adhesive application process, the application range of the adhesive applied to the second planned adhesion region S2 (the planned adhesion region of the positioning fixture 18 and the holding unit 20) of the window plate 12. Is made wider than the outer shape of the end face on the bonding side of the pedestal 19 and the holding part 20 of the positioning fixture 18, so that the entire end face of the holding part 20 can be securely adhered to the adhesive layer and held. The portion 20 can be securely bonded and fixed to the window plate 12.

  Furthermore, in the first embodiment, in the adhesive application step, the position of the application head 28 for applying the adhesive to the window plate 12 is fixed and the window plate 12 is moved, so the application head 28 is moved. Compared with the case where the adhesive is applied, the configuration of the adhesive application device 24 can be simplified and the cost can be reduced, and the robot that has moved the window plate 12 until the end of the adhesive application process. The window plate 12 can be smoothly transported to the next heating / drying process using the above system.

  Further, in the first embodiment, in the adhesive application step, the first planned adhesion region S1 (the planned adhesion region of the shielding member 15) and the second planned adhesion region S2 (the positioning fixture 18) of the window plate 12. And the adhesive layer 31 and 32 of both of the planned adhesion regions S1 and S2 are continuously applied to the adhesive planned region of the holding unit 20 via the adhesive continuous region S3. As a result, it is not necessary to divide the work of applying the adhesive onto the window plate 12 in a plurality of times, the work of applying the adhesive can be simplified and performed efficiently, and the adhesive is uniformly applied to each of the planned bonding areas S1 and S2. Stable adhesive strength can be obtained by making the thicknesses and drying times of the adhesive layers 31 and 32 in the respective adhesion planned regions S1 and S2 substantially the same.

  Furthermore, in Example 1, since the application portion of the adhesive of the window plate 12 was previously heated in the drying process before the molding process, the window plate 12 was not subjected to the injection molding of the polymer material. The solvent of the applied adhesive can be stably volatilized, and the adhesive strength can be stabilized.

  Next, Embodiment 2 of the present invention will be described with reference to FIG. However, substantially the same parts as those in the first embodiment are denoted by the same reference numerals, and the description will be simplified. The parts different from the first embodiment will be mainly described.

  In the first embodiment, the shielding member 15 and the holding portion 20 are molded with the positioning fixture 18 set in the injection mold 35. However, in the second embodiment, the shielding member 15 and the holding member 20 are held by a polymer material. After the portion 20 is molded, the positioning fixture 18 prepared separately in advance is attached to the holding portion 20.

As shown in FIG. 8, in the second embodiment, the space for setting the positioning fixture 18 is omitted from the injection mold 48 used in the molding process. In the molding step, only the window plate 12 coated with the adhesive in the same manner as in the first embodiment is set in the injection mold 48, and the polymer material is transferred from the injection gates 38 and 39 to the cavities 36, 37, the shielding member 15 and the holding portion 20 are independently molded, and the shielding member 15 and the holding portion 20 are formed on the back surface of the window plate 12 via the adhesive layers 31 and 32. Adhering and fixing to the opaque colored layer 14.
After completion of the molding process, the positioning fixture 18 separately prepared in advance is attached to the holding portion 20.

  In the second embodiment, after the shielding member 15 and the holding portion 20 are molded with the polymer material, the positioning fixture 18 is mounted on the holding portion 20, so the positioning fixture 18 is set in the molding die 48 at the time of molding. This eliminates the need to do this, reduces restrictions on the cavity shape of the mold 48 and the shape of the positioning fixture 18, simplifies the configuration of the molding die 48, and increases the degree of freedom in designing the positioning fixture 18. Thus, there is an advantage that the positioning fixture 18 having a complicated shape can be used.

  Next, Embodiment 3 of the present invention will be described with reference to FIGS. However, parts that are substantially the same as those in the first and second embodiments are denoted by the same reference numerals, and the description will be simplified. Mainly, differences from the first and second embodiments will be described.

  In the second embodiment, only the portion of the holding portion 20 that holds the positioning fixture 18 is formed by injection molding of the same polymer material as that of the shielding member 15, but in the third embodiment, as shown in FIG. In addition, the window assembly 49 simultaneously molds the positioning member 50 for positioning the window plate 12 with respect to the window frame portion 13 by injection molding of the same polymer material as that of the shielding member 15 to form the back surface of the window plate 12. The opaque colored layer 14 is adhesively fixed. The positioning member 50 is formed by coaxially forming a pedestal portion 51 and a small-diameter protrusion 50 a having a tapered surface on the tip side. When the window assembly 49 is attached to the window frame portion 13, The protrusion 50a is inserted into the engagement hole 23 of the flange portion 22 of the window frame portion 13 and the end surface 51a of the pedestal portion 51 is brought into contact with the flange portion 22, so that the interval between the flange portion 22 and the window plate 12 is constant. In this state, the window assembly 49 can be positioned with respect to the window frame portion 13 in a direction parallel to the surface of the window plate 12.

  In the case of manufacturing the window assembly 49 having the above-described configuration, in the adhesive application step, the adhesion planned area of the shielding member 15 and the adhesion planned area of the positioning member 50 in the back surface of the window plate 12 are the same as in the first embodiment. In addition, the adhesive is continuously applied so that the adhesive layers 31 and 52 in both of the planned bonding regions are continuous through the continuous adhesive region.

  As shown in FIG. 10, the injection mold 53 used in the molding process is provided with a shielding member molding cavity 36 and a positioning member molding cavity 54 for molding the positioning member 50 independently. Yes. Shield member forming injection gates 38 are provided at a plurality of locations of the shielding member forming cavities 36, and positioning member forming injection gates 43 are provided in the positioning member forming cavities 54.

  In the molding process, only the window plate 12 coated with the adhesive is set in the injection mold 53, and the polymer material is injected into the cavities 36 and 54 from the injection gates 38 and 43, respectively. Thus, the shielding member 15 and the positioning member 50 are formed independently, and the shielding member 15 and the positioning member 50 are bonded and fixed to the opaque colored layer 14 on the back surface of the window plate 12 through the adhesive layers 31 and 52. .

  When the window assembly 49 manufactured in this way is attached to the window frame portion 13, as shown in FIG. 9, the protrusions 50 a of the positioning members 50 fixed to the back surface of the window plate 12 are respectively connected to the window. The window 13 is inserted into the engagement hole 23 of the flange portion 22 of the frame portion 13 so that the end surface 51a of the pedestal portion 51 is brought into contact with the flange portion 22 and the distance between the flange portion 22 and the window plate 12 is kept constant. Positioning the assembly 11 with respect to the window frame 13 prevents the window assembly 49 from being displaced until the sealant 47 is cured.

  In the third embodiment described above, since the shielding member 15 and the positioning member 50 are simultaneously injection-molded with the polymer material, the positioning member 50 can be molded with the polymer material that molds the shielding member 15. There are advantages that the number of points can be reduced, and the labor for attaching the positioning member 50 is not required, and the manufacturing cost of the window assembly 49 can be reduced.

  Next, a fourth embodiment in which the present invention is applied to a window assembly for an automobile quarter window will be described with reference to FIGS. However, substantially the same parts as those in the first embodiment are denoted by the same reference numerals, and the description will be simplified. The parts different from the first embodiment will be mainly described.

  As shown in FIGS. 11 and 12, a long shielding member 57 has a front side 56 a on the outer peripheral edge of the window plate 56 on the window plate 56 (quarter window glass) of the window assembly 55 for quarter windows. It is provided along the excluded part. This shielding member 57 is formed from the front surface to the back surface of the outer peripheral edge of the window plate 12, and is bonded and fixed via an adhesive layer 58 applied to both the front and back surfaces and the end surface of the outer peripheral edge of the window plate 56, A lip portion 60 that closes the gap between the window frame portion 59 and a decorative portion 61 that covers the outer peripheral edge of the surface of the window plate 56 are integrally formed.

  In the case of manufacturing the window assembly 54, in the adhesive application step, both of the planned adhesion regions are included in the planned adhesion region of the shielding member 57 of the window plate 56 and the planned adhesion region of the positioning fixture 18 and the holding unit 20. The adhesive is continuously applied so that the adhesive layers 58 and 32 are continuous through the continuous adhesive region.

  In the molding process, the window plate 12 and the positioning fixture 18 to which an adhesive is applied are set in an injection mold (not shown), and a polymer material is injected into each cavity from each injection gate. By filling, the shielding member 57 and the holding portion 20 are independently formed, and the shielding member 57 and the holding portion 20 are bonded and fixed to the window plate 56 via the adhesive layers 58 and 32.

As in the second embodiment, the positioning fixture 18 may be attached to the holding portion 20 after the shielding member 57 and the holding portion 20 are formed of a polymer material.
Alternatively, as in the third embodiment, the entire positioning member 50 may be formed by injection molding of the same polymer material as that of the shielding member 57 and bonded and fixed to the back surface of the window plate 56.

Next, Embodiment 5 of the present invention will be described with reference to FIGS.
The injection mold 62 used for manufacturing the window assembly has a holding part forming cavity 37 for forming the holding part 20 as compared with the volume of the shielding member forming cavity 36 for forming the long shielding member 15. Therefore, when the polymer material is injected and filled into the cavities 36 and 37 in the molding process, the holding portion molding cavity 37 is filled with the polymer material in a short time and shielded. A large molding pressure is applied to the glass window plate 12 for a long time until the filling of the member molding cavity 36 is completed. At this time, the portion of the window plate 12 to which molding pressure is applied is received and supported by the injection mold 62 from the opposite surface side (front surface side). However, the window plate 12 is not a simple flat surface but is loose. Since it is formed in a curved shape, it is difficult to make the window plate 12 and the injection mold 62 closely contact each other without any gap due to manufacturing variations of the window plate 12 (variations in curvature of the glass surface). A slight gap is unavoidable. For this reason, when a large molding pressure is applied to the glass window plate 12 for a long time in the molding process, a large bending force works on the glass window plate 12 for a long time due to the presence of the gap, which is the cause. Thus, the glass window plate 12 may be cracked or cracked.

  As a countermeasure, in the fifth embodiment, in the molding process, the molding pressure of the polymer material injected and filled in the holding portion molding cavity 37 is an allowable limit value (a limit value at which the window plate 12 does not crack or crack). There is provided a pressure rise limiting means for limiting the pressure not to exceed.

  As shown in FIGS. 13 and 14, the pressure increase limiting means of the fifth embodiment is outside the range where the second adhesive layer 32 is applied in the vicinity of the holding portion molding cavity 37 of the injection mold 62. A discharge cavity 63 is provided, and a discharge path 64 for discharging the polymer material to the discharge cavity 63 is provided on the opposite side of the injection gate 39 in the holding portion molding cavity 37. In this configuration, in the process in which the pressure of the polymer material injected and filled into the holding portion molding cavity 37 rises to the vicinity of the allowable limit value, a part of the polymer material in the holding portion molding cavity 37 passes through the discharge path 64. The opening shape of the discharge path 64 is designed so as to pass through the discharge cavity 63.

  Further, the discharge path 64 is formed with a narrow portion 65 in which the channel cross-sectional area is flatter and smaller than other portions of the channel. The narrow portion 65 is formed so as to be positioned at or near the outer peripheral edge of the adhesive layer 32 formed in the planned adhesion region of the holding portion 20. Other configurations are the same as those of the first embodiment.

  In the molding process, in the state where the window plate 12 and the positioning fixture 18 are set in the injection mold 62, the polymer material is injected into the cavities 36 and 37 from the injection gates 38 and 39, and filled. The shielding member 15 and the holding part 20 are formed. At that time, in the holding portion molding cavity 37, the polymer material injected from the injection gate 39 reaches the discharge path 64 located on the opposite side of the injection gate 39 after being substantially filled in the holding portion molding cavity 37. . In the process in which the polymer material is excessively supplied into the holding portion molding cavity 37 and the pressure of the polymer material rises to the vicinity of the allowable limit value, the excess polymer material in the holding portion molding cavity 37 becomes the subsequent polymer material. And the pressure of the polymer material in the holding portion molding cavity 37 is restricted so as not to exceed the allowable limit value.

  In this molding step, as shown in FIG. 15, the holding portion 20 formed by the holding portion forming cavity 37 and the discharge polymer portion 66 formed by the discharge cavity 63 are connected to a connecting portion 67 formed by the discharge path 64. The narrow portion 68 is formed by the narrow portion 65 in a part of the connecting portion 67.

  When it is necessary to remove the discharged polymer portion 66, the slender portion 68 formed in the connecting portion 67 is torn or cut after the molding step, so that the holding portion 20 and the discharged polymer portion 66 are separated from the thin portion 68. And the discharged polymer portion 66 may be removed.

  In the fifth embodiment described above, the discharge cavity 63 communicating with the holding portion molding cavity 37 via the discharge path 64 is provided so that the pressure of the polymer material in the holding portion forming cavity 37 does not exceed the allowable limit value. Since part of the polymer material in the holding portion molding cavity 37 is discharged to the discharge cavity 63 through the discharge path 64, the pressure of the polymer material in the holding portion forming cavity 37 exceeds the allowable limit value. The pressure of the polymer material in the holding portion molding cavity 37 can be increased moderately while restricting so that the holding portion 20 and the window plate 12 are molded with the polymer material in the holding portion molding cavity 37. While ensuring the adhesive strength and formability, it is possible to prevent an excessive pressure from being applied to the window plate 12 and to prevent the window plate 12 from cracking or cracking.

  In addition, the polymer material first injected has a lot of heat taken away by contact with the flow path (runner 40, sprue 42, etc.) and the cavity 37, and starts to solidify due to a decrease in temperature during the flow process. Since the polymer material that has started to be pushed out from the holding portion molding cavity 37 to the discharge cavity 63 by the subsequent polymer material, the holding portion molding cavity 37 can be filled with a well-melted polymer material. . For this reason, the adhesive strength and moldability of the holding | maintenance part 20 shape | molded with the polymer material in the cavity 37 for holding | maintenance part shaping | molding and the window board 12 can be improved further. In addition, there is an advantage that this effect can be realized with a simple configuration in which the discharge cavity 63 and the discharge path 64 are provided.

  Moreover, in the fifth embodiment, since the discharge path 64 is provided on the opposite side of the injection gate 39 in the holding portion forming cavity 37, the polymer material injected from the injection gate 39 is used for forming the holding portion. After being almost filled in the cavity 37, it reaches the discharge passage 64 located on the opposite side of the injection gate 39 and is discharged to the discharge cavity 63 without leaving an unfilled portion of the polymer material in the holding portion molding cavity 37. The polymer material can be surely filled to every corner in the holding portion molding cavity 37.

  Further, in the fifth embodiment, a narrow portion 68 is formed by a narrow portion 65 in a part of a connecting portion 67 formed by a discharge passage 64, and the thin portion 68 is torn or cut and held. Since the portion 20 and the discharged polymer portion 66 are separated by the thin portion 68, the operation of separating the holding portion 20 and the discharged polymer portion 66 can be facilitated. The shape of the narrow portion 65 is not limited to a flat shape, and for example, the cross-sectional shape may be a circle, an ellipse, a triangle, a quadrangle, or the like.

Next, Embodiment 6 of the present invention will be described with reference to FIG.
The injection mold 69 of the sixth embodiment includes a pressure sensor 70 (pressure detection means) that detects the pressure of the polymer material in the holding portion molding cavity 37 and a sprue that supplies the polymer material into the holding portion molding cavity 37. There is provided an open / close valve 71 for opening and closing 42 (supply path). The on-off valve 71 is driven to open and close by an actuator 72 such as a hydraulic cylinder, and the output signal of the pressure sensor 70 is input to the control device 73 of the injection mold 69. The control device 73 controls the actuator 72 based on the pressure of the polymer material in the holding portion molding cavity 37 detected by the pressure sensor 70 to control the on-off valve 71, and polymer into the holding portion molding cavity 37. By controlling the supply amount of the material, the pressure of the polymer material in the holding portion molding cavity 37 is limited so as not to exceed the allowable limit value. The pressure sensor 70, the on-off valve 71, the actuator 72, the control device 73, and the like serve as pressure increase limiting means. Other configurations are the same as those of the first embodiment.

  In the molding process, with the window plate 12 and the positioning fixture 18 set in the injection mold 69, the polymer material is injected into the cavities 36 and 37 from the injection gates 38 and 39, and filled. The shielding member 15 and the holding part 20 are formed. At that time, the control device 73 determines that the pressure of the polymer material in the holding portion molding cavity 37 detected by the pressure sensor 70 reaches a predetermined determination value (for example, a value that is the same as or slightly lower than the allowable limit value). Determine whether or not.

  If the pressure of the polymer material in the holding portion molding cavity 37 does not reach the judgment value, the sprue 42 is held in the open state by holding the on-off valve 71 in the fully open position (position indicated by the solid line in FIG. 16). Then, a polymer material is supplied into the holding portion molding cavity 37.

  Thereafter, when the pressure of the polymer material in the holding portion molding cavity 37 reaches a judgment value, the open / close valve 71 is moved to the fully closed position (position indicated by a dotted line in FIG. 16) to close the sprue 42. Then, the supply of the polymer material into the holding portion molding cavity 37 is stopped. Thus, the pressure of the polymer material in the holding portion molding cavity 37 is limited so as not to exceed the allowable limit value.

  Note that the control method of the on-off valve 71 may be changed as appropriate. For example, the opening degree of the on-off valve 71 is reduced in accordance with the pressure detected by the pressure sensor 70, and the polymer material into the holding portion molding cavity 37 is changed. By reducing the supply flow rate, the pressure of the polymer material in the holding portion molding cavity 37 may be limited so as not to exceed the allowable limit value.

  In the sixth embodiment described above, the pressure of the polymer material in the holding portion molding cavity 37 can be controlled while monitoring the actual pressure of the polymer material in the holding portion molding cavity 37 with the pressure sensor 70. Therefore, the pressure of the polymer material in the holding portion molding cavity 37 can be accurately limited to the allowable limit value or less, and the occurrence of cracks and cracks in the window plate 12 can be more reliably prevented, and the holding portion can be prevented. Adhesive strength and moldability between 20 and the window plate 12 can also be improved.

  In the sixth embodiment, the on-off valve 71 is provided in the supply path (sprue 42) for supplying the polymer material into the holding portion molding cavity 37. However, the discharge for discharging the polymer material in the holding portion molding cavity 37 is performed. Holding is performed by providing an opening / closing valve on the path and controlling the amount of polymer material discharged from the holding portion molding cavity 37 by controlling the opening timing or opening degree of the opening / closing valve based on the pressure detected by the pressure sensor 70. The pressure of the polymer material in the part molding cavity 37 may be limited so as not to exceed the allowable limit value.

  Further, in each of the above Examples 5 and 6, as in Example 1, the holding portion 20 is molded with the positioning fixture 18 set in the injection mold 62 (65). As in the second embodiment, the positioning fixture 18 may be attached to the holding portion 20 after the holding portion 20 is molded.

As in the third embodiment, when the positioning member 50 is simultaneously molded by injection molding of the same polymer material as that of the shielding member 15, the positioning member 50 is injected into the positioning member molding cavity 54 for molding the positioning member 50. Then, the pressure of the filled polymer material may be limited by the pressure increase limiting means so that the pressure does not exceed the allowable limit value.
In each of the above Examples 2 to 6, the injection gate portion is automatically broken when the window assembly is removed.

  In each of the first to sixth embodiments described above, the position of the coating head 28 is fixed and the window plate 12 (56) is moved in the adhesive coating step, but the position of the window plate 12 (56) is changed. The application head 28 may be moved while being fixed.
