Description

  The present invention relates to a glass run and a method for producing the same.

  Generally, a glass run is provided along the inner periphery of a door frame of an automobile. When viewed from the cross-sectional direction, the glass run includes a base portion and a vehicle body side wall portion extending from the base portion and a vehicle body side wall portion and a vehicle outer side wall portion. It has a car outer seal lip. The glass run is sealed so that the body portion is attached to a mounting portion (channel portion) provided along the inner periphery of the door frame, and the peripheral portions of the inner and outer surfaces of the door glass are sandwiched between both seal lips. Is done.

  In addition, the glass run is composed of an extrusion molding part formed in a substantially linear shape and a mold forming part that connects the extrusion molding parts at a predetermined angle, for example, along the shape of the door frame. The front vertical side portion, the upper side portion, and the rear vertical side portion (see, for example, Patent Document 1).

  By the way, in the case where the glass run as described above is composed of an extrusion molding part and a mold molding part, the connection line between the extrusion molding part and the mold molding part appears on the appearance, resulting in the appearance quality. There is a risk of lowering. In addition, the composition material may be different between the extrusion molding part and the mold molding part, and there is a risk that the surface color and gloss will be greatly different. There is a risk of being invited.

  The mold forming part for forming the corner portion of the glass run includes a mold (core) for forming each inner peripheral surface of the main body, the vehicle inner side seal lip, and the vehicle outer side seal lip at the time of molding. In general, the inner side wall portion and the outer side wall portion of the vehicle are formed in an unfolded shape so that the holding strength of the core is maintained. However, when the vehicle inner side wall portion and the vehicle outer side wall portion are deformed so as to be narrowed when being attached to the attachment portion, the bending angle of the mold forming portion (corner portion) may change. In this case, the entire shape of the glass run does not follow the shape of the attachment portion, which may cause deterioration of the state of attachment to the attachment portion.

Further, it has also been proposed that the glass run is divided into a vehicle interior component and a vehicle exterior component, and each is molded, and then the components are combined together (see, for example, Patent Document 2).

It is desirable to form a sliding layer by sticking or applying a sliding agent.

  When employing the technique of the above-mentioned Patent Document 2, the operation of forming the sliding layer as described above is performed at a stage where the vehicle exterior component and the vehicle interior component are separated, so that the vehicle exterior side wall portion can be used in the operation. And there is a merit that it is not necessary to push and widen the inner side wall portion.

  However, even if the technique of the above-mentioned Patent Document 2 is adopted, when the sliding layer is formed, a process for forming the sliding layer is required separately from the mold forming process. As a result, the manufacturing workability may be reduced. Further, if the formation of the sliding layer is attempted at the stage where the vehicle exterior structure and the vehicle interior structure are separated, there is a risk that the number of times of sticking and application will increase accordingly.

  Here, the molding of the vehicle interior mold body 22 will be described with reference to FIG. FIG. 3 shows a cross section of the mold apparatus 40 in a state in which the PE sheets 55 and 56 that constitute the sliding layers 28 and 29 are set in the cavity 46 and then clamped.

  First, in a state where the mold apparatus 40 is opened, the PE sheet 55 is set on the molding surface for molding the door glass sliding surface of the vehicle interior seal lip 13 in the first die 41, and the second The PE sheet 56 is set on the molding surface for molding the inner surface of the base portion 14 in the mold 42. At this time, the PE sheets 55 and 56 are sucked into the suction means 53 through the suction holes 51 and 52, and the PE sheets 55 and 56 are brought into close contact with the corresponding molding surfaces, and the positional deviation thereof is regulated. The In the present embodiment, since the positional deviation of the PE sheets 55 and 56 is restricted when the PE sheets 55 and 56 are set on the molding surface, the installation process and the deviation prevention process are performed almost simultaneously. It becomes.

  Then, the PE sheets 55 and 56 are clamped while being sucked by the suction means 53, and the plasticized TPV is injected into the cavity 46 of the mold apparatus 40 and filled. After completion of solidification, the mold is opened, and the molded vehicle interior mold body 22 is removed from the mold apparatus 40. As a result, the vehicle interior mold body 22 in which the vehicle interior sliding layer 28 and the base side sliding layer 29 are formed is obtained. The vehicle exterior mold body 21 is also manufactured based on the same process as the vehicle interior mold body 22 using a corresponding mold device. That is, the outside sliding layer 27 is formed at the same time as molding.

  Subsequently, the vehicle exterior mold body 21 and the vehicle interior mold body 22 that have been molded as described above are assembled. That is, in the present embodiment, the engaging convex portion 26 is engaged with the engaging concave portion 25. Thereby, the cross-sectional shape which has the main-body part 11, the seal lips 12, 13, etc. as mentioned above is comprised, and the longitudinal direction whole area | region of the glass run 1 which comprises the upper side part 2, the front vertical side part 3, and the back vertical side part 4 is comprised. Is configured.

  As described above in detail, in the present embodiment, the vehicle outer mold body 21 and the vehicle inner mold body 22 are assembled to form the upper side portion 2, the front vertical side portion 3, and the rear vertical side portion 4. The entire longitudinal direction of the glass run 1 is configured. That is, the glass run 1 can be composed only of a molded body. For this reason, for example, the case where the connecting line between the extrusion molded body and the molded body appears in the appearance as in the case where the glass run 1 is formed by connecting the extruded body and the molded body in the longitudinal direction. It can be avoided. In addition, it is possible to avoid a situation in which a difference in color / gloss partially occurs in the longitudinal direction (circumferential direction) of the glass run 1. As a result, the appearance quality is improved. Moreover, the possibility that a step is formed in the longitudinal direction of the glass run 1 can be avoided, and the sealing performance can be improved.

  Further, since the vehicle exterior seal lip 12 is provided on the vehicle exterior mold body 21 and the vehicle interior seal lip 13 is disposed on the vehicle interior mold body 22, the glass run 1 is connected to the vehicle exterior side wall 15 and the vehicle interior side. It is not necessary to form the unfolded shape so that the side wall portion 16 greatly expands, and it is possible to obtain a shape that does not need to greatly change the cross-sectional shape when attaching to the channel portion DC (sash portion DS). Therefore, it is possible to stabilize the mounting state of the glass run 1 with respect to the channel portion DC, improve the sealing performance, and the like.

  Further, according to the present embodiment, the sliding layers 27, 28, and 29 are formed at the same time when the vehicle exterior mold body 21 and the vehicle interior mold body 22 are molded. That is, the molded products 21 and 22 in which the sliding layers 27, 28, and 29 are formed are obtained by insert-molding the PE sheet at the time of molding. Therefore, in order to form the sliding layers 27, 28, and 29, a tape material is formed on the sliding surfaces of the door glass of the vehicle outer side seal lip 12 and the vehicle inner side seal lip 13 and the inner side surface of the base portion 14 after the molding. The work of sticking or applying a sliding agent can be omitted, and the manufacturing workability can be improved.

  In addition, since the TPV that constitutes the glass run 1 (the vehicle exterior mold body 21 and the vehicle interior mold body 22) and the PE sheet that constitutes the sliding layers 27, 28, and 29 have compatibility, separately. Even without using an adhesive or the like, both can be firmly bonded.

  Further, when molding the vehicle interior mold 22, the PE sheets 55 and 56 are set in the cavity 46 in order to form the sliding layers 28 and 29. The PE sheets 55 and 56 set in are sucked into the suction means 53 through the suction holes 51 and 52. Accordingly, the PE sheets 55 and 56 are brought into close contact with the corresponding molding surfaces, and the positional deviation of the PE sheets 55 and 56 is restricted. In this state, TPV in a plasticized state is injected into the cavity 46. Therefore, when the TPV is injected into the cavity 46 and filled, the PE sheets 55 and 56 are displaced, or the TPV enters between the PE sheets 55 and 56 and the molding surface corresponding thereto. Therefore, it is possible to prevent the possibility that the PE sheets 55 and 56 are no longer exposed on the surface of the vehicle interior molded body 22. Therefore, the PE sheets 55 and 56 can be reliably exposed on the surface at the intended positions, and the sliding layers 28 and 29 can be formed more accurately. Of course, the vehicle exterior mold body 21 is also manufactured based on the same process as that of the vehicle interior mold body 22, and the same operational effects are exhibited.

  Further, for example, in the case where a PE sheet is pasted after molding to form a sliding layer on the door glass sliding surfaces of the vehicle-side seal lip 12 and the vehicle-side seal lip 13 that are curved. Such work may be relatively difficult, and workability and quality may be deteriorated. In this respect, in the present embodiment, the sliding layers 27 and 28 can be formed on the door glass sliding surfaces of the vehicle outer side seal lip 12 and the vehicle inner side seal lip 13 at the same time as the molding, and at appropriate positions. These problems can be eliminated.

  In addition, the base side sliding layer 29 provided corresponding to the inner side surface of the base portion 14 is formed only on the vehicle interior side mold body 22 (vehicle interior base piece portion 14b). On the other hand, for example, when the base-side sliding layer 29 is formed not only on the vehicle interior mold body 22 but also on the vehicle exterior mold body 21, It becomes necessary to perform an operation for forming the sliding layer 29 (an operation of installing a PE sheet or the like). Further, not only the mold apparatus 40 for molding the vehicle interior mold body 22 but also the mold apparatus for molding the vehicle exterior mold body 21 to form the base side sliding layer 29. Therefore, it becomes necessary to form a mechanism (such as providing a suction hole) for preventing the displacement of the PE sheet. In this regard, in the present embodiment, the work for forming the base side sliding layer 29 is only required once (the entire base side sliding layer 29 is simultaneously formed by molding the vehicle interior mold body 22. Therefore, the above-mentioned trouble can be prevented.

  Moreover, in this embodiment, the engagement convex part 26 and the engagement recessed part 25 are provided, and the vehicle exterior type molded object 21 and the vehicle interior type molded object 22 are assembled | attached directly. For this reason, for example, compared with the case where the molded bodies 21 and 22 are connected with an adhesive, it takes time for the adhesive to dry, or the adhesive-coated surfaces of the molded bodies 21 and 22 are pressed against each other. Since it is not necessary to hold in a state, it is possible to suppress a decrease in manufacturing workability.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the suction means 53 is used to bring the PE sheets 55 and 56 (sliding members) into close contact with the molding surface and maintain the close contact state. However, the configuration is limited to such a configuration. Instead, it is sufficient that the sliding member is not displaced when TPV is injected into the cavity 46 and filled. For example, displacement of the sliding member may be prevented using static electricity. In this case, since the holding force can be uniformly applied to the entire surface of the sliding member, it is possible to prevent the sliding member from partially rising from the molding surface.

  Further, as shown in FIG. 4, a restricting portion 59 that locks the end portion of the sliding member 58 may be provided for a part of the mold (for example, the second die 42). In this case, even if no suction means or the like is provided, the restricting portion 59 can restrict the displacement of the sliding member 58 toward the general part, and as a result, the sliding member can be suppressed while suppressing an increase in cost. Can be prevented. Moreover, it is also possible to combine with the structure which sucks the sliding member in the said embodiment, In that case, the shift | offset | difference movement (an edge part lifts from a molding surface) in the edge part of a sliding member more reliably Can be prevented.

  (B) In the above embodiment, the glass run 1 is divided at the base portion 14 into the vehicle exterior mold body 21 and the vehicle interior mold body 22, but is not particularly limited to such a configuration. For example, the glass run is made up of 3 of an exterior mold body having at least an exterior seal lip 12, a base side mold body having at least a base portion 14, and an interior mold body having at least an interior seal lip 13. It may be divided into two.

  (C) In the above-described embodiment, the vehicle exterior mold body 21 and the vehicle interior mold body 22 are assembled by engaging the engagement protrusion 26 with the engagement recess 25. The configuration is not limited. However, in the assembled state of the vehicle exterior mold body 21 and the vehicle interior mold body 22, the displacement between the mold bodies 21 and 22 in the longitudinal direction of the glass run 1, the thickness direction of the base portion 14, and the vehicle width direction. It is desirable to restrict movement. In this case, the vehicle exterior mold body 21 and the vehicle interior mold body 22 can be assembled accurately, and the assembled state can be stabilized.

  (D) In the above embodiment, the glass run 1 (molded bodies 21 and 22) is made of TPV, and a polyethylene sheet is adopted as the sliding member. Instead, for example, the glass run 1 may be composed of non-crosslinked olefinic thermoplastic elastomer (TPO) or EPDM. In addition, when both the moldings 21 and 22 and the constituent materials of the sliding member are made of an olefin elastomer, the moldings 21 and 22 and the sliding member can be firmly joined (thermal joining).

  Further, the constituent material of the base side sliding layer 29 may be different from the constituent material of the vehicle outer side sliding layer 27 and the vehicle inner side sliding layer 28. In addition, the vehicle exterior mold body 21 and the vehicle interior mold body 22 can be colored according to the vehicle outer plate color and the interior color, respectively.

  (E) In the above embodiment, the sliding layers 27, 28, and 29 are formed on the door glass sliding surfaces of the vehicle outer side seal lip 12 and the vehicle inner side seal lip 13 and the inner side surface of the base portion 14, respectively. However, it is not particularly limited to such a configuration, and any one of the sliding layers 27, 28, and 29 may be formed. For example, the base side sliding layer 29 may be omitted over the entire area of the glass run 1, or the sliding layers 27 and 28 in a predetermined section of the glass run 1 may be omitted. Even in the case where the sliding layers 27, 28, 29 are partially and intermittently formed in the longitudinal direction of the glass run 1, the glass run 1 is constituted by a molded body as described above. Therefore, it can be formed relatively easily and accurately.

  (F) The cross-sectional shape of the glass run 1 is not particularly limited as long as it includes at least the main body 11 and the pair of seal lips 12 and 13. For example, the molding lips 17 and 18 and the protrusion 31 may be omitted.

  In the above embodiment, the glass run 1 for the front door has been described in detail. Similarly, in the glass run for the rear door, the sliding layer is formed simultaneously when the molded bodies 21 and 22 are molded. It is good as well.

  (G) Although not specifically mentioned in the above embodiment, as shown in FIGS. 5A and 5B, the vehicle interior slides with respect to the door glass sliding surface of the vehicle interior seal lip 13 which is a curved surface. On one side of the PE sheet 55 for forming the layer 28, for example, a plurality of rows of recesses 72 that form grooves 71 having a substantially V-shaped cross section or thin portions may be provided. In this case, the PE sheet 55 can be smoothly deformed along the molding surface of the mold (for example, the first mold 41) constituting the cavity 46. Therefore, the PE sheet 55 and the molding surface can be brought into close contact with each other relatively easily and more reliably, and the manufacturing workability and the product quality can be improved. It is to be noted that a similar effect can be obtained by forming a groove or a recess in the PE sheet for forming the vehicle exterior sliding layer 27 with respect to the vehicle exterior seal lip 12.

  Further, as shown in FIGS. 5A and 5B, the PE sheet 55 is set so that the surface on which the groove 71 and the recess 72 are formed faces the inner peripheral side of the cavity 46. 55, the surface area of the surface embedded in the vehicle interior mold body 22 is increased, and the PE sheet 55 can be more firmly bonded to the vehicle interior mold body 22. The PE sheet 56 for forming the base-side sliding layer 29 is also formed by forming grooves and recesses and setting the forming surface facing the inner peripheral side of the corresponding cavity during mold forming. Similar effects are achieved.
