Description

  The present invention relates to a film-in-mold product.

JP 2003-251633 A

  Conventionally, a resin molded product used as an interior material of an automobile is formed by placing a film having a surface state according to the purpose in a cavity of a mold and then injecting a resin serving as a resin injection molding part. In addition, a molding method in which the film is formed in close contact with the surface side of the plate-like main body portion in the resin injection molding portion, that is, molding by a so-called film-in-mold method is performed. Under the present circumstances, in order to improve the adhesiveness between a film and a main-body part, the contact bonding layer is formed among them.

  In such a resin molded product, as shown in FIG. 12, since protrusions 42 such as fastening bosses and reinforcing ribs are simultaneously formed on the back surface of the plate-like main body 41, the positions of these protrusions 42 are thick. There is a problem that sink 410 occurs on the surface side of the surface and a dent 210 occurs on the design surface on the surface side. In order to solve this problem, for example, there is a technique that suppresses sink marks by a technique such as Patent Document 1, or a technique that makes the dent inconspicuous by applying a texture process to the surface.

  By the way, in recent years, there is a demand to improve the design property by finishing the surface of the main body portion of the resin molded product to be a design surface so as to have gloss. However, when gloss is provided on the surface of the main body, there is a problem that a dent appears remarkably due to the reflection of light even with a slight sink. Even if the sink is at a level that was not noticed in the past, it is clearly noticeable if the surface of the main body is glossy.

  An object of the present invention is to provide a film-in-mold molded product in which unevenness due to sink marks does not appear on the design surface.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the film-in-mold molded product of the present invention is
A film in-mold comprising: a resin injection molding part having a plate-like main body part; and a film that is arranged on the first main surface of the main body part via an adhesive layer and integrated with the main body part by insert molding In the molded product, the resin injection molded part is a plane in which a resin protruding part protruding from the second main surface of the main body part is integrally formed with the main body part and includes the second main surface of the main body part of the resin protruding part. The adhesive layer missing region is formed by partially missing the adhesive layer in the plane at a position that overlaps with the projecting portion sectional region, which is a sectional region by projection.

  Generally, sink marks are likely to occur on the back side of the main body portion where the resin protrusion is formed. According to the configuration of the present invention, since the adhesive layer is not formed on the portion of the first main surface of the main body portion where the sink is likely to occur, the adhesion between the main body portion and the film is weak, and the Even if it occurs, it is possible to reduce the dent of the film that follows it.

  The adhesive layer missing region can be formed so as to projectly include the protruding portion cross-sectional region. According to this configuration, the adhesive layer missing region can be formed so as to include a projection region obtained by orthogonally projecting the projecting section sectional region onto the first main surface. That is, it can be formed so that at least the projected region is an adhesive layer missing region. Sinking is likely to occur in this projection area on the back side of the resin protrusion, but since the adhesive layer is not formed in this part, the film covering this part will not be recessed following the sinking. Therefore, it is possible to effectively suppress the occurrence of dents on the film surface.

  In the above configuration, the outer peripheral edge of the adhesive layer missing region can be shaped to follow the outer peripheral edge of the protruding section cross-sectional region. According to this configuration, the adhesive layer missing region is formed in the same shape as the base end cross section of the protruding portion where sink marks are generated. Thereby, since an adhesion layer lacking area | region can be formed in an effective shape with respect to the generation | occurrence | production expected part of sink, the generation | occurrence | production of the dent of the film surface by sink can be suppressed effectively.

  The adhesive layer missing region in the configuration of the present invention can be formed in a larger area than the protruding portion cross-sectional region. If an adhesive layer missing region having the same size and shape is formed on the projection region obtained by orthogonally projecting the cross-sectional area of the protrusion on the first main surface, the film covering the adhesive layer missing region swells outward. May occur. By forming the adhesive layer missing region in a larger area than the protruding portion cross-sectional region as in the above configuration, the swelling of the film can be alleviated.

  In this case, the adhesive layer missing region can be formed so as to have an outer peripheral region extending with a predetermined width along the periphery of the protruding portion cross-sectional region. According to this configuration, since the adhesive layer missing region can be formed also in the outer peripheral region of the projecting section cross-sectional region, the problem of film swelling can be solved. Moreover, since an outer peripheral area | region is formed in the suitable shape according to the protrusion part cross-sectional area | region, the swelling of a film can be relieve | moderated effectively.

  Moreover, the said outer peripheral area | region can be formed so that it may have an intermediate | middle area | region where the existing area and non-existing area | region of an adhesive layer alternate in the circumferential direction. According to this configuration, the adhesive layer absence region in the outer peripheral region of the adhesive layer missing region is formed, so that the swelling of the film can be effectively reduced, while the adhesive layer existing region is partially formed in the outer peripheral region. By doing so, the adhesion between the film and the main body in this outer peripheral region can be strengthened.

  Further, the outer peripheral region is formed such that a non-existing region continuous forming portion where the non-existing region of the adhesive layer is continuously formed in the circumferential direction is in contact with the projecting portion cross-sectional region, and outside the non-existing region continuous forming portion. An intermediate region may be formed. As a result, a non-existing region continuous forming part for more effectively suppressing the swelling of the film is provided on the outer peripheral side of the adhesive layer missing region, and further, the adhesive layer non-existing region is provided on the outer side thereof to swell the film. Can be effectively mitigated. And since the contact bonding layer presence area | region is formed in the circumferential direction side of the contact bonding layer non-existence area | region, the close_contact | adherence with a film and a main-body part becomes firm.

  The resin projecting portion of the present invention can be a fastening boss formed in the projecting height direction in such a manner that the fastening hole opens at the tip end surface of the projecting portion. Since the fastening boss is formed with a certain thickness (thickness) in view of forming a hole in the inner peripheral portion, sink marks are likely to occur on the back surface side. By forming the adhesive layer missing region corresponding to such a boss, it is possible to prevent the film from being dented by sink marks generated in this portion.

  The resin protrusion of the present invention can be a reinforcing rib that reinforces the main body of the resin injection molded part. There is a possibility that sink marks may occur on the back side of the reinforcing rib formed with a certain thickness or more, and the adhesive layer missing region as described above is formed correspondingly, and this portion is generated. The sinking of the film due to sink can be suppressed.

  Of the resin protrusions of the present invention, the adhesive layer missing region can be formed corresponding to only a predetermined thickness or more. Sinks are unlikely to occur when the thickness of the cross-sectional area of the protrusion is small. According to the said structure, an adhesion layer missing area can be provided only with respect to the resin protrusion part in which sink is anticipated. Note that the reference thickness of the resin protrusion for determining whether or not to provide the adhesive layer missing region is, for example, 50% of the plate thickness of the plate-like main body, and the thickness of the resin protrusion is When the thickness is equal to or greater than the reference thickness, the adhesive layer missing region can be formed. In the present invention, the thickness of the resin protrusion compared with the reference thickness is a cross section of the resin protrusion by a plane parallel to the second main surface of the main body, in particular, a plane including the second main surface. It is the thickness (wall thickness or plate thickness) of the resin protrusion in the cross section of the resin protrusion.

  In the said invention, the main surface opposite to the adhesion side to the main-body part of a film can be made into a glossy design surface. When the main surface of the film that is the design surface of the film-in-mold molded product is the glossy design surface opposite to the adhesion side to the main body, the unevenness of the film surface that becomes the design surface becomes easier to visually recognize. Even a dent or bulge is conspicuous and the design is deteriorated. However, in the case of the present invention in which the adhesive layer lacking region as described above is provided, even if the design surface (film surface) of the film-in-molded product is a glossy design surface, the level at which indentations and bulges generated on the design surface cannot be visually recognized. And can be shown as a smoothly continuous curved surface or flat surface.

  The adhesive layer missing region of the adhesive layer of the present invention can be patterned by screen printing. The presence region and non-existence region (adhesion layer missing region) of the adhesive layer can be easily formed by screen printing.
