Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foam-integrated foam product used as an interior part of an automobile, for example, for an instrument panel.

[0002]

2. Description of the Related Art Conventionally, this type of skin-integrated foam molded article is formed by foaming and curing a foamed resin material between a skin and a core material. Leakage from the joint with the material impairs the appearance, so it is necessary to take measures for sealing the joint. As a countermeasure against such a seal, there is known one in which a sealing material is interposed in the above-mentioned joint (for example, see Japanese Patent Application Laid-Open No. 8-281670).
In this device, an upright wall constituting an accommodating recess for accommodating a foam layer is formed in a core material, while a peripheral upright portion having a shape in which a peripheral edge of a skin is bent to the back side thereof is formed, and a sealing material is interposed therebetween. In this state, the upright wall and the peripheral upright portion are opposed to each other to form a joint. Then, by using the foaming pressure of the foamed resin material foamed between the core material and the skin, the peripheral upright portion of the skin, the seal material and the upright wall of the core material are brought into close contact with each other, so that the foamed resin material is It is assumed that leakage is prevented. In the invention described in the above-mentioned publication, by adopting a soft foam sealing material having open cells as the sealing material, the gas generated as the foaming of the foamed resin material progresses is stored through the soft foam sealing material. While the resin material is discharged out of the recess, the leakage of the foamed resin material out of the housing recess is prevented by the seal material itself.

[0003]

By the way, in the case of an instrument panel of an automobile, for example, it is generally practiced to provide a textured surface with a concave or convex pattern (texture) on the surface of the skin. Is required to be in close contact with the upright wall of the core material. However, even if the aperture that appears on the surface of the skin, that is, the aperture is formed only on the skin main body, and the peripheral erected part is mirror-finished, the mirror-finished surface of the peripheral erected part is not May appear slightly on the surface. For this reason, it is necessary to form the squeeze from the skin main body portion to a part of the base end side region of the peripheral upright portion. However, when the aperture is formed to a part of the peripheral upright portion in this manner, the wall thickness of the proximal end region of the peripheral upright portion where the aperture is formed is different from that of the mirror-finished distal side region. Therefore, the mirror-finished region does not come into contact with the upright wall of the core material. In particular, when the foaming pressure is weak, such as in the initial stage of foaming of the foamed resin material, a sufficient sealing property is obtained even if a sealing material is interposed at a joint portion as in a conventional skin integral foam molded product. However, there is a disadvantage that the foamed resin raw material leaks out and the appearance of the instrument panel deteriorates.

The present invention has been made in view of such circumstances, and an object of the present invention is to improve the sealing performance without using a sealing material, and to provide a foamed resin even in the initial stage of foaming. An object of the present invention is to improve the appearance by reliably preventing leakage of raw materials.

[0005]

In order to achieve the above object, the invention according to claim 1 is based on a skin integral foam molded article in which a foam layer is integrally formed between a core material and a skin. . In this, an upright wall is formed around the core material, the upright wall constituting an accommodating recess for accommodating the foam layer inside the opening corresponding to the formation region of the skin, and a bottom side of the upright wall and an opening. A step is formed at an intermediate position between the side and the side such that the bottom side of the housing recess is narrower than the opening side. And a skin body that covers the opening of the housing recess, and a peripheral edge that is bent from the periphery of the skin body to the back side of the skin body so that the front side contacts the inner circumferential surface of the upright wall. The peripheral upright portion is provided integrally with the upright portion, and the peripheral edge upright portion has a configuration in which a tip side portion extends to a bottom side position from the step portion and is pressed against the upright wall by the foam layer. .

[0006] In the case of the above construction, the front end portion of the peripheral upright portion of the skin is formed so as to extend to the bottom side from the step provided on the upright wall of the core material. The step portion exerts a force to bend inward of the accommodation recess. For this reason, due to the elastic restoring force of the peripheral upright portion of the skin, a reaction force is generated in the peripheral upright portion in a direction in which the peripheral upright portion comes into close contact with the upright wall of the core material, and the tip side portion of this peripheral upright portion is pressed against the upright wall. You. For this reason, even if a squeeze is formed in the base end side region of the peripheral upright portion, the tip end portion can be brought into close contact with the upright wall of the core material, and in the initial stage of foaming of the foamed resin raw material. Therefore, even when the foaming pressure is not so much acting on the peripheral upright portion, it is possible to sufficiently secure the sealing property and reliably prevent the foamed resin material from leaking.

[0007] When the foaming of the foamed resin material proceeds, the foaming pressure causes the peripheral upright portion to press against the upright wall of the core material, thereby ensuring the sealing property of the joint and ensuring the foamed resin material. Can be more reliably prevented from leaking. As a result, the appearance of the integrally molded skin product is improved.

Further, in forming the outer skin, it is only necessary to form a peripheral upright portion having a shape obtained by merely bending the peripheral edge, thereby facilitating the molding.

According to a second aspect of the present invention, in the first aspect of the invention, a concave groove is formed in the peripheral upright portion so as to open opposite to the step portion of the upright wall and to be recessed inward of the housing concave portion. The peripheral edge standing portion has a configuration in which a portion on the tip side of the concave groove extends to a position on the bottom side of the step portion and is in contact with the standing wall.

In the case of the above construction, even if the foamed resin material tries to flow out of the housing recess through the space between the peripheral upright portion and the upright wall, the foamed resin material that is going to flow out is indented into the concave groove and the step. It accumulates in the space formed by the section and stops further progress. Therefore, as long as the space is not filled with the foamed resin material, the foamed resin material does not flow out from this space to the surface side, thereby making it possible to more reliably prevent the foamed resin material from leaking. become. As a result, the appearance of the skin-integrated foam molded article is improved.

The rigidity of the peripheral upright portion is improved by the concave groove provided in the peripheral upright portion, and it is possible to prevent the skin itself from waving. For this reason, it becomes possible to aim at facilitation of the molding of the skin-integrated foam molded article and improvement of appearance.

The invention according to claim 3 is based on a skin integral foam molded article in which a foam layer is integrally formed between a core material and a skin. In this, an upright wall is formed around the core material, the upright wall constituting an accommodating recess for accommodating the foam layer inside the opening corresponding to the formation region of the skin, and a bottom side of the upright wall and an opening. An inclined surface is formed closer to the opening than the intermediate position between the sides, so that the opening area increases as approaching the opening. And a skin body that covers the opening of the housing recess, and a peripheral edge that is bent from the periphery of the skin body to the back side of the skin body so that the front side contacts the inner circumferential surface of the upright wall. The peripheral upright portion is formed integrally with the upright portion, and the peripheral edge upright portion has a configuration in which a tip side portion extends to a bottom side position from the intermediate position and is pressed against the upright wall by the foam layer. .

[0013] In the case of the above configuration, the front end portion of the peripheral upright portion of the skin extends to the bottom side of the accommodating recess beyond the inclined surface formed on the upright wall of the core material, and the peripheral upright portion of the skin is upright. Because the wall is pressed inward by the inclined surface of the wall, the elastic restoring force of the peripheral upright portion generates a reaction force in a direction in which the peripheral upright portion comes into close contact with the upright wall of the core material. For this reason, even if a constriction is formed in the base end region of the peripheral upright portion, the distal end portion can be brought into close contact with the upright wall. As a result, even when the foaming pressure is not so much acting on the peripheral erected portion in the initial stage of foaming of the foamed resin material, the sealing property is sufficiently secured and the foamed resin material is reliably prevented from leaking. It becomes possible to do.

As the foaming of the foamed resin material progresses, the foaming pressure causes the peripheral upright portion to press against the upright wall of the core material, thereby ensuring the sealing property of the joint and ensuring the foamed resin material. Can be more reliably prevented from leaking. As a result, the appearance of the integrally molded skin product is improved.

In the molding of the core material, since the inclined surface is not provided over the entire area from the distal end to the proximal end of the upright wall, molding is facilitated. Further, in forming the outer skin, it is only necessary to form a peripheral upright portion having a shape obtained by merely bending the peripheral edge, so that the molding is facilitated. Thereby, it is possible to achieve both improvement in the sealability of the joint portion and improvement in the moldability of the core material and the skin.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

<First Embodiment> FIG. 1 shows an instrument panel 1 as a skin-integrated foam molded product according to a first embodiment of the present invention.
Is composed of an upper panel portion 1a constituting an upper half portion and a lower panel portion 1b constituting a lower half portion. Then, the upper panel portion 1a is shown in FIGS.
As shown in FIG. 3, the foamed layer 7 is integrally formed between the core material 3 and the skin 5 to form a three-layer structure, and the lower panel portion 1b has a single-layer structure composed of only the core material 3. As a material of the instrument panel 1, for example, acrylonitrile-butadiene-styrene (AB
S) A hard resin such as a resin, a soft resin such as polyvinyl chloride (PVC) as the skin 5, and a hard foamed resin such as hard polyurethane as the foamed layer 7 may be used. The core member 3 may be formed by compression molding or injection molding, and the skin 5 may be formed by slash molding or vacuum molding.

As shown in FIGS. 2 to 4, the core member 3 has an upright wall 1 which forms a housing recess 9 for housing the foam layer 7.
Numeral 1 is provided so as to correspond to the entire periphery of the upper panel 1a which is a skin formation region. And on this standing wall 11,
A step 13 is formed such that the bottom side 11a of the housing recess 9 is narrower than the opening side 11b.

On the other hand, the skin 5 includes a skin main body 21 that covers the opening of the accommodation recess 9, and a peripheral upright 15 that bends from the periphery of the skin main body 21 and abuts on the inner peripheral surface of the upright wall 11. And are integrally formed. In the peripheral upright portion 15, the concave groove 1 which is open opposite to the step portion 13 of the upright wall 11 and which is recessed inward of the housing concave portion 9.
7 are formed, and the concave groove 17 is formed in an elongated band shape over the entire periphery of the peripheral upright portion 15. Also,
The peripheral upright portion 15 has a front end portion 15 a at a bottom side 1 side of a step portion 13 formed on the upright wall 11 of the core material 3.
It is formed to a length that can contact the portion 1a. And
In a region R1 from the skin main body portion 21 to the base end region of the peripheral upright portion 15, a constriction of an uneven pattern is formed on the surface, while a distal end region R2 of the peripheral upright portion 15 is formed by the core. The surface of the material 3 which comes into contact with the upright wall 11 is mirror-finished. Therefore, the region R where the aperture is formed is formed.
1 and the region R2 where the aperture is not formed, the thickness is t.
1 (see FIG. 3).

Next, molding of the instrument panel 1 with the core material 3 and the skin 5 will be described.

First, the upper mold is connected to the upper mold and the lower mold by a hinge, and the upper mold is rotated upward with the hinge as a fulcrum to open the mold, and in this state, the core material 3 is removed from the upper mold. While the skin 5 is set in a lower mold.

Next, a foamed resin material is poured onto the skin 5 set in the lower mold, and then the upper mold is rotated downward with the hinge as a fulcrum to close the mold.

When the foamed resin material is foamed and cured, the instrument panel 1 in which the foam layer 7 is interposed between the core material 3 and the skin 5 can be obtained, and the upper die is supported on the hinge as a fulcrum. The instrument panel 1 is opened by rotating in the direction, and the molded instrument panel 1 is removed from the mold.

Next, the operation and effect of the first embodiment will be described.

The front end portion 15 of the peripheral upright portion 15 of the skin 5
a is formed so as to extend to a position on the bottom side 11 a from the step 13 provided on the upright wall 11 of the core material 3, and the peripheral upright portion 15 is formed on the inner side of the accommodation recess 9 by the step 13. Since the force for bending acts on the peripheral upright portion 15, a reaction force in a direction in which the peripheral upright portion 15 comes into close contact with the upright wall 11 of the core material is generated by the elastic restoring force of the peripheral upright portion 15. The tip side portion 15 a is pressed against the upright wall 11. For this reason, even in the initial stage of foaming of the foamed resin raw material and the foaming pressure is not so much acting on the peripheral upright portion 15, the tip side portion 15 a of the peripheral upright portion 15 is securely brought into close contact with the upright wall 11. In this way, the sealing property can be sufficiently secured, and the leakage of the foamed resin material can be prevented.

If the height t2 of the step 13 is set so as to satisfy t2 ≧ t1, the tip portion 15a of the peripheral upright portion 15 will be described.
Can be reliably pressed against the upright wall 11. Here, t1 is a thickness difference between the region R1 and the region R2 (see FIG. 3).

If the foaming of the foamed resin material proceeds, the foaming pressure causes the peripheral upright portion 15 to come into pressure contact with the upstanding wall 11 of the core member 3, thereby ensuring the sealing property of the joint and the above foaming. Leakage of the resin raw material can be more reliably prevented. As a result, the instrument panel 1
Can be improved in appearance.

Even if the foamed resin material tries to flow out of the accommodating recess 9 through the space between the peripheral upright portion 15 and the upright wall 11, the foamed resin material that is going to flow out is not covered by the concave groove 17. Is accumulated in the space formed by the step portion 13 and further progress is stopped.
For this reason, as long as the space is not filled with the foamed resin material, the foamed resin material does not flow out from this space to the surface side of the skin 5, thereby preventing leakage of the foamed resin material more reliably. be able to. As a result, the appearance of the instrument panel 1 can be improved.

Further, the concave groove 17 provided in the peripheral upright portion 15 improves the rigidity of the peripheral upright portion 15 and can prevent the skin 5 itself from waving. Therefore, it is possible to facilitate the molding of the instrument panel 1 and improve the appearance.

<Second Embodiment> FIG. 5 shows a cross section of a joint portion of a skin-integrated foam molded product according to a second embodiment of the present invention.
This is applied to an instrument panel 1 of an automobile as in the first embodiment (see FIG. 1). In the same manner as in the first embodiment, the core member 3 is provided with an upright wall 11 constituting the housing recess 9, while the outer periphery of the skin 5 is bent inward of the housing recess 9. A peripheral edge upright portion 15 having a formed shape is formed.

As shown in FIG. 5, unlike the first embodiment, the upright wall 11 of the core member 3 has an inclined surface 19.
Are integrally formed. The inclined surface 19 is inclined by an angle α so that the opening area 11b becomes larger as the opening side 11b becomes closer to the opening than the intermediate position P between the bottom side 11a and the opening side 11b of the upright wall 11. It is formed.

Further, the present embodiment differs from the first embodiment in that the peripheral upright portion 15 protruding from the outer skin 5 is not formed with a concave groove. The portion 15a is formed so as to have a length capable of abutting on the bottom side 11a with respect to the intermediate position P formed on the upright wall 11 of the core material 3. The skin 5 has an aperture formed in the region R1 as in the first embodiment, while the surface of the region R2 has a mirror-finished surface, and the region R1 and the region R2 have the same thickness. The thickness differs by t1.

In the case of the second embodiment, the front end portion 15a of the peripheral upright portion 15 is connected to the upright wall 11 of the core material 3.
Is extended to a position on the bottom side 11a from the intermediate position P formed on the outer surface. As a result, a reaction force is generated in the peripheral upright portion 15 in a direction in which the peripheral upright portion 15 comes into close contact with the upright wall 11 due to the elastic restoring force of the peripheral upright portion 15. Thereby, even if the aperture is formed in the region R1, the peripheral edge upright portion 15 and the upright wall 11 are formed.
Can be brought into close contact with each other. As a result, it is possible to improve the sealing property of the joint portion, and even in the initial stage of foaming of the foamed resin material, it is possible to sufficiently secure the sealing property and reliably prevent the foamed resin material from leaking. it can.

When the foaming of the foamed resin material progresses, the peripheral upright portion 15 comes into pressure contact with the upright wall 11 of the core member 3 due to the foaming pressure. Leakage of the resin raw material can be more reliably prevented. As a result, the instrument panel 1
Can be improved in appearance.

In the molding of the core material 3, the inclined surface 19 is not provided over the entire area from the tip to the base end of the upright wall 11, so that the molding of the core material 3 can be facilitated. On the other hand, in forming the outer skin 5, it is only necessary to form the peripheral upright portion 15 having a shape obtained by merely bending the peripheral edge, so that the molding is facilitated. As a result, it is possible to achieve both the improvement in the sealing property of the joint and the improvement in the moldability of the core material 3 and the skin 5.

<Other Embodiments> The present invention relates to the first embodiment.
The present invention is not limited to the second embodiment, and includes various other embodiments. That is, in the first embodiment, the concave groove 17 is formed in the peripheral upright portion 15 of the skin 5.
Is provided, but is not limited to this. For example, FIG.
As shown in (1), the peripheral upright portion 15 may not have a concave groove. Even in this case, the tip side portion 15a of the peripheral upright portion 15 is formed by the upright wall 1 of the core material 3.
1 is extended to a position on the bottom side 11a than the step 13 formed in the step 1, and the step 13 pushes the peripheral upright portion 15 toward the inside of the housing recess 9. A reaction force is generated by the elastic restoring force of the peripheral upright portion 15, and the peripheral upright portion 15 comes into close contact with the upright wall 11 by the reactive force. For this reason, even if a throttle is formed in the region R1, the front end side portion 15a comes into pressure contact with the upright wall 11, so that the sealing property is improved and leakage of the foamed resin material can be reliably prevented. When the foaming of the foamed resin material progresses, the foaming pressure allows the peripheral upright portion 15 to be in close contact with the upright wall 11, thereby ensuring the sealing property of the joining portion and preventing the leakage of the foamed resin material. It can be more reliably prevented. as a result,
The appearance of the instrument panel 1 can be improved. Furthermore, as described above, by not providing a groove on the peripheral upright portion 15, in forming the skin 5, the peripheral upright portion 15 whose peripheral edge is simply bent inward of the housing concave portion 9 is formed. I just need. Therefore, it is possible to facilitate the molding of the skin 5. The step 1
The height t2 of 3 may be set higher than the thickness difference t1 of the skin 5 between the region R1 and the region R2 as in the first embodiment.

In the first and second embodiments, the peripheral upright portion 15 of the skin 5 is formed to have such a length that the leading edge thereof is not in contact with the bottom surface of the housing recess 9 of the core material 3. But,
However, the present invention is not limited to this. For example, the leading edge of the peripheral upright portion may be formed so as to extend until it contacts the bottom surface of the housing recess 9. In this case, at the initial stage of foaming of the foamed resin material, the step 13
Alternatively, the force for holding down the inner side of the accommodation recess 9 can be more reliably applied by the inclined surface 19,
Moreover, as the foaming of the foamed resin material progresses, the foaming pressure allows the peripheral upright portion to more securely adhere to the upright wall 11. As a result, it is possible to ensure the sealing property of the joint portion and to more reliably prevent the leakage of the foamed resin material.

In the first and second embodiments, in the region R1 from the skin main body portion 21 of the skin 5 to the base end side region of the peripheral upright portion 15, a constriction of an uneven pattern is formed on the surface. However, the present invention is not limited to this. Even in this case, the step 13 or the inclined surface 1 formed on the upright wall 11 of the core 3
According to 9, it is possible to ensure the sealing property of the joint at the initial stage of foaming of the foamed resin raw material, and if the foaming of the foamed resin raw material proceeds, the foaming pressure causes the peripheral edge rising portion to press against the rising wall. Thus, it is possible to ensure the sealing property of the joint portion and to more reliably prevent the leakage of the foamed resin raw material.

In the first and second embodiments, the skin-integrated foam molded article is applied to the instrument panel 1 as the foam-integrated foam, but the invention is not limited to this. It may be applied to molding of door trims, console boxes, and the like.

It is formed so as to extend to the bottom side, and furthermore, a force acting to bend inward of the accommodation concave portion by the step portion acts on the peripheral upright portion. A reaction force is generated in the peripheral upright portion in a direction in which the peripheral upright portion comes into close contact with the upright wall of the core member, and the front end portion of the peripheral upright portion can be pressed against the upright wall. For this reason, even if a constriction is formed in the base end region of the peripheral upright portion, the distal end portion can be brought into close contact with the upright wall of the core material, and the sealing performance of the joint portion can be improved. it can. As a result, even in the initial stage of foaming of the foamed resin material, it is possible to sufficiently secure the sealing property and reliably prevent the foamed resin material from leaking.

When the foaming of the foamed resin material progresses, the foaming pressure causes the peripheral upright portion to press against the upright wall of the core material, thereby ensuring the sealing property of the joint and ensuring the foaming resin material. Leakage can be more reliably prevented. As a result, the appearance of the skin-integrated molded product can be improved.

Further, in forming the outer skin, it is only necessary to form a peripheral upright portion having a shape in which the peripheral edge is bent inward of the housing recess, so that the molding can be facilitated.

According to the second aspect of the invention, in addition to the effect of the first aspect, even if the foamed resin raw material flows out of the housing recess through the space between the peripheral upright portion and the upright wall. Even if it is attempted, the foamed resin raw material that has flowed out is accumulated in the space formed by the concave groove and the step, and further progress is stopped. For this reason, as long as the space is not filled with the foamed resin material, the foamed resin material does not flow out from this space to the surface side, whereby leakage of the foamed resin material can be more reliably prevented. . As a result, the appearance of the skin-integrated foam molded article can be improved.

Furthermore, the concave groove provided in the peripheral upright portion enhances the rigidity of the peripheral upright portion and prevents the skin itself from waving, thereby facilitating the molding of the foam-integral foam molded article. The appearance can be improved.

Of the peripheral upright portion is held inward of the housing recess by the inclined surface of the upright wall, and the elastic restoring force of the above upright peripheral upright portion causes the peripheral upright portion to have a reaction force in a direction of pressing against the upright wall of the core material. Is generated, and the tip side portion of the peripheral upright portion can be pressed against the upright wall. For this reason, even if a constriction is formed in the base end region of the peripheral upright portion, the distal end portion can be brought into close contact with the upright wall, and even in the initial stage of foaming of the foamed resin raw material, the sealing property is improved. A sufficient amount of the resin material can be reliably prevented from leaking.

As the foaming of the foamed resin material progresses, the foaming pressure causes the rising edge of the peripheral edge to press against the rising wall of the core material, thereby ensuring the sealing property of the joint and ensuring the sealing property of the foamed resin material. Leakage can be more reliably prevented. As a result, the appearance of the skin-integrated molded product can be improved.

Further, in the molding of the core material, the inclined surface is not provided over the entire area from the leading end to the base end of the upright wall, so that the formability can be improved. Since it is only necessary to form the peripheral upright portion having a shape that is only bent, the molding can be facilitated. As a result, it is possible to achieve both improvement in the sealability of the joint and improvement in the moldability of the core material and the skin.
