Description

  The present invention relates to a molded product assembly in which a mounting member is mounted on an extrusion molded product, and a manufacturing method thereof.

  As a known example of this type of molded product assembly, for example, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2002-46478), the length of a belt molding or the like along the window opening edge of an automobile door is described. There is one in which a long extruded product is attached to seal between the door panel and the window glass. In general, long extrudates such as belt moldings are formed by cutting a polymer material that has been continuously formed by extrusion molding into a predetermined length. There is one that covers the cut end face part.

In this case, the following method is known as a method for fixing the mounting member.
For example, when a plastically deformable core material such as a metal plate is embedded in the extrusion molded product, a part of the back surface side of the extrusion molded product is plastically deformed and engaged with the mounting member to perform extrusion molding. There is one in which the mounting member is fixed to the product.

In some cases, the mounting member is fixed to the extruded product by injecting an adhesive between the extruded product and the mounting member and bonding them together.
JP 2002-46478 A (the third page etc.)

  However, in the former method in which a part of the back side of the extruded product is plastically deformed and engaged with the mounting member, the outer surface of the extruded product is deformed due to the plastic deformation of the back side of the extruded product. May look bad. In addition, in the case of an extrusion molded product having a configuration in which a plastically deformable core material such as a metal plate is omitted in consideration of recyclability and the like, a fixing method by plastic deformation of the extruded product cannot be employed.

  Also, in the latter method, the method of adhering an extruded product and a mounting member with an adhesive causes the adhesive strength of the adhesive to decrease due to deterioration over time depending on the use environment, etc., and the mounting member is peeled off from the extruded product. There is a fear. In addition, it is necessary to use an adhesive that can be bonded to both the extruded product and the mounting member, but depending on the combination of the material forming the extruded product and the mounting member, an appropriate adhesive cannot be found, and the mounting member cannot be used. It may not be possible to bond. For this reason, the combination of the material forming the extrusion molded product and the mounting member is limited, and the degree of freedom in selecting the molding material of the extrusion molded product or the mounting member is narrowed. However, there is a drawback that it is not possible to select a material with priority.

  The present invention has been made in view of these circumstances. Therefore, the object of the present invention is to fix the mounting member to the extruded product with stable strength without plastic deformation of the extruded product. It is possible to increase the degree of freedom in selecting materials for forming the extruded product and the mounting member.

  In order to achieve the above object, a molded product assembly according to claim 1 of the present invention includes a long extruded product that is formed by extrusion molding of a polymer material and cut into a predetermined length, and the extruded product. And a mounting member that is molded separately from the molded product and is mounted on the extruded product, and is attached to a predetermined attached body or used with a predetermined mounting body attached thereto. By joining a connecting member molded so as to surround or cover at least a part of the mounting member by injection molding of a polymer material compatible with the polymer material forming the product, it is connected to at least a part of the extruded product. The member and the mounting member are fixed to the extruded product.

  Thus, by fusing the connecting member formed so as to surround or cover the mounting member to the extruded product, the mounting member can be mechanically fixed to the extruded product with the connecting member. Accordingly, the mounting member can be fixed to the extruded product with stable strength without plastic deformation of the extruded product. In addition, since there is no need to fuse or bond the extruded product and the mounting member, the degree of freedom in selecting the molding material for forming the extruded product or the mounting member can be expanded. Cost, moldability, and design properties It is possible to select a material giving priority to the like. However, the present invention does not prohibit, as an auxiliary fixing means, plastic deformation of the extruded product and engagement with the mounting member, or fusion or bonding of the extruded product and the mounting member.

  When the molded product assembly of the present invention is manufactured, as in claim 9, the extrusion molded product and the mounting member are set in a predetermined injection mold, and then compatible with the polymer material forming the extruded molded product. The connecting member is molded so as to surround or cover at least a part of the mounting member by heating and melting the polymer material having the above-described properties. It is preferable that the connecting member and the mounting member are fixed to the extruded product by being fused to the portion. Thereby, the molded product assembly of this invention can be manufactured by injection molding.

  In this case, as in claim 10, when the connecting member is injection-molded, the polymer material forming the connecting member is heated and melted at a temperature higher than the melting temperature of the polymer material forming the extruded product, and then injected. It is preferable to do. If it does in this way, at the time of injection molding of a connection member, a contact part with a connection member of an extrusion-molded product can be certainly melted, and a connection member can be certainly fused to an extrusion-molded product.

  Further, as in claims 2 and 11, the mounting member may be formed with a through hole and / or a notch in a portion where the connecting member is provided. In this way, at the time of injection molding of the connecting member, the polymer material forming the connecting member can flow through the through hole or notch of the mounting member, so the injection pressure of the polymer material forming the connecting member can be reduced. Even if it is not so high, the polymer material forming the connecting member can be flowed to the extruded product side, and the connecting member can be fused to the extruded product, thereby improving the injection moldability. In addition, since the connecting member is partially filled in the through hole or notch of the mounting member, the mounting member and the connection member can be entangled to more firmly fix the mounting member.

  In addition, as in claims 3 and 12, the mounting member may be integrally formed in advance with a mounting portion that is mounted on the mounted body or used when the mounting body is mounted. Since the mounting member molded separately from the extruded product does not need to consider compatibility with the material forming the extruded product, the mounting portion is formed by integrally forming the mounting portion on the mounting member. The attachment portion can be formed of a material suitable for the above.

  Alternatively, when the connecting member is injection-molded as in claims 4 and 13, the connecting member is attached to the attached body or an attachment portion used when the attaching body is attached is integrally formed on the connecting member. You may do it. In this way, the attachment portion can be formed at an accurate position without being affected by the positional relationship between the extruded product and the mounting member.

  According to a fifth aspect of the present invention, the attachment portion may be formed in a cylindrical shape that protrudes to the back surface side of the extruded product and that can be screwed into a screw member such as a screw or a tapping screw. In this way, when the molded product assembly is attached to the mounted body (or when the mounting body is attached to the molded product assembly), the cylindrical mounting portion can be used as a boss portion for tightening the screw member. it can.

  In this case, as in claim 6, a reinforcing portion for reinforcing the mounting portion may be formed on the outer peripheral side of the cylindrical mounting portion. If it does in this way, when a screw member is tightened in an attaching part, it can prevent as much as possible that the attaching part spreads in the diameter direction, and is cracked by the reinforcement effect of a reinforcing part.

  According to a seventh aspect of the present invention, the mounting member is integrally formed with a lid that covers an end surface in the longitudinal direction of the extruded product and a fixed piece that extends along the extruded product, and the fixed piece is connected to the connecting member. May be fixed to the extruded product. If it does in this way, the cut end face of an extrusion-molded product can be covered with the cover part of a mounting member.

  Moreover, you may form an extrusion molded product as a belt molding which can be attached along the window opening edge of a vehicle body. In this way, it is possible to fix attachment members such as end caps to the belt molding with stable strength without plastic deformation of the belt molding, and freedom of selection of materials forming the belt molding and the attachment member. Can expand the degree.

  Hereinafter, three embodiments 1 to 3 in which the present invention is applied to a belt molding assembly attached along the window opening edge of an automobile door will be described.

A first embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, window frames 13 and 14 are integrally provided on a front door 11 and a rear door 12 of an automobile, respectively, and window glasses 15 and 16 can be opened / closed up and down on the window frames 13 and 14, respectively. Is provided. In addition, long belt molding assemblies 19 and 20 (molded product assemblies) are attached to the outer door panels 17 and 18 (attached bodies) of the doors 11 and 12, respectively, along the lower edge of the window opening. The belt molding assemblies 19 and 20 seal between the outer door panels 17 and 18 and the window glasses 15 and 16.

  Next, the configuration of the belt molding assembly 19 of the front door 11 will be described with reference to FIGS. As shown in FIGS. 2 and 3, the belt molding body 21 is an extruded product formed by cutting a polymer material continuously formed by extrusion molding into a predetermined length. A separately formed end cap 22 (mounting member) is covered to cover the cut end surface portion.

  As shown in FIG. 4, the belt molding body 21 has a substantially inverted U-shaped cross section. When the belt molding main body 21 is attached to the outer door panel 17, the belt molding main body 21 is covered with the upper edge flange portion 23 of the outer door panel 17. Thus, the locking piece 21c formed at the lower end of the side wall portion 21a on the vehicle inner side of the belt molding main body 21 is locked to the lower end of the upper edge flange portion 23.

  The belt molding body 21 includes a shielding lip 25 that protrudes from the upper end portion toward the window glass 15 and an upper contact lip that protrudes toward the window glass 15 from the side wall 21a on the vehicle interior side of the belt molding body 21. 26, a lower contact lip 27, a cushion portion 28 projecting downward from the lower end of the side wall portion 21b of the belt molding main body 21 toward the outer door panel 17 side, and an inner peripheral surface of the belt molding main body 21 to the inside. A plurality of protruding ridges 29 to 32 projecting toward each other are fused and integrated by coextrusion molding.

  When the belt molding body 21 is mounted on the outer door panel 17, the cushion portion 28 and the protrusions 29 to 32 abut against the outer door panel 17, respectively, and the upper edge is caused by the elastic force of the protrusions 29 to 31. While sandwiching the flange portion 23, the ridge 32 is engaged with the lower end of the flange portion 23 so that the belt molding main body 21 is held in a positioned state. Further, the upper contact lip 26 and the lower contact lip 27 are in contact with the surface of the window glass 15 to seal between the outer door panel 17 and the window glass 15.

  As the polymer material for molding the belt molding body 21, for example, an olefin-based thermoplastic resin in which talc is blended as a filler in PP (polypropylene) is used. Moreover, the polymer material which shape | molds the shielding lip 25, the contact lips 26 and 27, the cushion part 28, and the protrusions 29-32 is a polymer material compatible with the polymer material which forms the belt molding main body 21, for example, a belt A thermoplastic elastomer such as TPO (olefin-based thermoplastic elastomer) that is softer and more flexible than the molding body 21 is used. Further, a colored film layer 33 such as urethane resin is formed on the surface of the belt molding body 21 (at least the surface outside the vehicle), and on the surfaces of the contact lips 26 and 27 (at least the contact surface with the window glass 15), The low friction material layer 34 is formed by flocking such as nylon pile.

  As shown in FIGS. 2 and 3, the belt molding body 21 has the locking piece 21 c and the contact lips 26, 27 removed from the portion (range indicated by W <b> 1 in FIG. 3) attached to the window frame 13, and The side wall 21a and the ridge 29 on the inner side of the vehicle are removed at the portion where the end cap 22 is mounted and in the vicinity thereof (range indicated by W2 in FIG. 3).

  As shown in FIGS. 5 to 7, the end cap 22 separately molded and attached to the belt molding main body 21 is formed by injection molding of a hard resin such as AES (acrylonitrile, ethylene propylene rubber, styrene), etc. A lid portion 35 that covers the end surface of the belt and a fixed piece 36 that extends along the belt molding body 21 are integrally formed. A plurality of notches 37 (see FIG. 6) are formed at the edge of the fixed piece 36, and a screw such as a screw or a tapping screw protrudes from the back of the belt molding body 21 at the center of the fixed piece 36. A cylindrical boss portion 39 (attachment portion) capable of fastening the member 38 is integrally formed. Further, a positioning hole 40 into which a positioning pin 49 (see FIG. 8) is inserted at the time of injection molding of a connecting member 42 described later is formed at a predetermined position of the fixed piece 36. Further, on the surface of the fixed piece 36 that faces the belt molding main body 21, a recess 41 (see FIG. 5) that avoids interference with the root portion 29 a remaining after the protrusion 29 is removed is formed. .

  As shown in FIG. 5, the connecting member 42 surrounds or covers the fixed piece 36 of the end cap 22 by injection molding of a polymer material, and a part of the connecting member 42 is filled in the notch 37 of the fixed piece 36. Thus, the connecting member 42 is molded, and the fixing piece 36 of the connecting member 42 and the end cap 22 is fixed to the belt molding body 21 by joining to the belt molding body 21 by heat fusion. A reinforcing portion 43 that reinforces the boss portion 39 is integrally formed with the connecting member 42 on the outer peripheral side of the boss portion 39 integrally formed with the end cap 22.

  The polymer material that forms the connecting member 42 and the reinforcing portion 43 is a polymer material that is compatible with the polymer material that forms the belt molding main body 21. For example, a thermoplastic elastomer such as TPO is used.

  Next, a method for manufacturing the belt molding assembly 19 will be described with reference to FIGS. As shown in FIGS. 8 and 9, the injection mold 44 used for manufacturing the belt molding assembly 19 is provided with a cavity 45 for molding the connecting member 42 and the reinforcing portion 43, and an injection nozzle of the injection molding machine. The heated and melted polymer material injected from (not shown) flows through the path of the runner 46 → the sprue 47 → the injection gate 48 → the cavity 45.

  In the molding process of the connecting member 42, first, the belt molding body 21 and the end cap 22 separately molded in advance are set in the injection mold 44, and the injection mold 44 is closed. Accordingly, the positioning pin 49 is inserted into the positioning hole 40 of the end cap 22 with the gap remaining between the belt molding main body 21 and the end cap 22, and the end cap 22 is positioned.

  Thereafter, the polymer material forming the connecting member 42 is heated and melted at a temperature higher than the melting temperature of the polymer material forming the belt molding body 21, preferably slightly higher, and injected from the injection gate 48 into the cavity 45. Fill. At that time, since the molten polymer material flows through the plurality of notches 37 formed in the fixed piece 36 of the end cap 22 by the injection pressure, the molten polymer material can be obtained without increasing the injection pressure of the molten polymer material. Can flow into the gap between the belt molding body 21 and the end cap 22. Also, the molten polymer material that has flowed into the cavity 45 flows into the enlarged bulging portion 50 formed at the end of the cavity 45, so that the molten polymer filled between the belt molding body 21 and the end cap 22 is filled. The amount of the material is appropriately adjusted to prevent the position of the end cap 22 from shifting in the direction away from the belt molding body 21 (upward in FIG. 8) when the molten polymer material is filled.

  In this molding process, the connecting member 42 surrounds or covers the fixed piece 36 of the end cap 22, and a part of the connecting member 42 is filled in a plurality of notches 37 formed in the fixed piece 36. The member 42 is molded and fused to the belt molding body 21 by heat in a state where the injection pressure is applied, whereby the connecting member 42 and the fixed piece 36 of the end cap 22 are fixed to the belt molding body 21. Further, a reinforcing portion 43 that reinforces the boss portion 39 is formed integrally with the connecting member 42 on the outer peripheral side of the boss portion 39 formed integrally with the end cap 19.

  Note that a plurality of protrusions 36a are provided on the surface of the fixed piece 36 of the end cap 22 that faces the vehicle outer side wall 21b of the belt molding main body 21 toward the vehicle outer side wall 21b. Therefore, when the belt molding body 21 and the end cap 22 are set in the injection mold 44, a gap 59 is formed between the belt molding body 21 and the fixed piece 36 of the end cap 22. When the polymer material forming the connecting member 42 is injection-molded, the polymer material wraps around the gap 59 and is fused to the belt molding main body 21 and surrounds the fixing piece 36 to fix the fixing piece 36 to the belt molding main body 21. .

  After the filled polymer material is cooled and solidified, the injection mold 44 is opened, and the belt molding assembly 19 in which the end cap 22 is fixed to the belt molding main body 21 by the connecting member 42 is removed from the injection molding mold 44. This completes the manufacture of the belt molding assembly 19.

  When the belt molding assembly 19 manufactured as described above is attached to the outer door panel 17, first, as shown in FIG. 4, the belt molding main body 21 is put on the upper edge flange portion 23 of the outer door panel 17, and the belt The locking piece 21 c of the molding body 21 is locked to the lower end of the upper edge flange portion 23. Thereafter, as shown in FIG. 5, a screw member 38 such as a screw or a tapping screw inserted into the screw insertion hole 51 of the outer door panel 17 is tightened into a boss portion 39 formed integrally with the end cap 22, thereby The molding assembly 19 is fixed to the outer door panel 17.

  In the first embodiment described above, the connecting member 42 is molded so as to surround or cover the fixed piece 36 of the end cap 22 by injection molding of a polymer material compatible with the polymer material forming the belt molding body 21. Since the connecting member 42 and the end piece 22 are fixed to the belt molding main body 21 by fusing the connecting member 42 to the belt molding main body 21, the end cap 22 is fixed to the belt molding main body 21 by the connecting member 42. 21 can be mechanically fixed. Accordingly, the end cap 22 can be fixed to the belt molding body 21 with a stable strength without necessarily plastically deforming the belt molding body 21 as in the prior art. In addition, since there is no need to fuse or bond the belt molding body 21 and the end cap 22, the degree of freedom in selecting a molding material for forming the belt molding body 21 and the end cap 22 can be expanded. In addition, it is possible to select a material giving priority to the cost, formability, designability, etc. of the end cap 22.

  In the present invention, as an auxiliary fixing means, a core material that can be plastically deformed, such as a metal plate, is embedded in the belt molding main body 21, and the belt molding main body 21 is plastically deformed to be engaged with the end cap 22. The belt molding main body 21 and the end cap 22 may be fused or bonded.

  In the first embodiment, when the connecting member 42 is injection-molded, the polymer material forming the connecting member 42 is heated and melted at a temperature higher than the melting temperature of the polymer material forming the belt molding body 21 and injected. Therefore, when the connecting member 42 is injection-molded, the contact portion of the belt molding main body 21 with the connecting member 42 is melted by the heat of the connecting member 42 and the injection pressure is applied to make the connecting member 42 the belt molding main body. 21 can be reliably fused.

  Furthermore, in the first embodiment, since the plurality of notches 37 are formed in the fixing piece 36 of the end cap 22, the polymer material forming the connecting member 42 is fixed to the fixing piece 36 during the injection molding of the connecting member 42. Even if the injection pressure of the polymer material forming the connection member 42 is not so high, the polymer material forming the connection member 42 is allowed to flow through the plurality of notches 37 formed in the belt molding body 21. The connecting member 42 can be fused to the belt molding body 21 by flowing in the gap between the end cap 22 and the end cap 22, and the injection moldability can be improved. In addition, since the plurality of notches 37 formed in the fixing piece 36 of the end cap 22 are partially filled with the connecting member 42, the fixing piece 36 of the end cap 22 and the connecting member 42 are entangled. The end cap 22 can be more firmly fixed.

  In the present invention, a plurality of through holes may be formed in the fixed piece 36 of the end cap 22 or a plurality of notches and through holes may be formed together.

  In addition, the end cap 22 formed separately from the belt molding main body 21 is not required to consider compatibility with the polymer material forming the belt molding main body 21, and in the first embodiment, the end cap 22 is used. Since the boss portion 39 is formed integrally with the fixed piece 36 of the cap 22 in advance, the boss portion 39 can be formed of a material suitable for forming the boss portion 39. Furthermore, when attaching the belt molding assembly 19 to the outer door panel 17, the belt molding assembly 19 is fixed to the outer door panel 17 by fastening the screw member 38 to the boss portion 39 formed integrally with the end cap 22. Can do.

  Further, in the first embodiment, since the reinforcing portion 43 that reinforces the boss portion 39 is formed on the outer peripheral side of the boss portion 39, when the screw member 38 is tightened into the boss portion 39, the boss portion It can be prevented by the reinforcing effect of the reinforcing portion 43 that 39 spreads in the radial direction and breaks.
