BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urethane skin and a method for molding the same, and more specifically, a urethane film formed by spraying a urethane material onto a molding surface of a mold has a predetermined shape and a predetermined shape. The present invention relates to a urethane skin formed by mounting a preformed specific member, and a molding method capable of suitably molding the urethane skin.

2. Description of the Related Art In a passenger compartment of a vehicle such as a passenger car, various vehicle interior members such as an instrument panel, a floor console and a door panel are provided. Since the color, design and texture of these vehicle interior members greatly affect the atmosphere and texture of the passenger compartment, the interior members are required to have improved texture and a sense of luxury. Therefore, in the vehicle interior member, by applying a preformed skin on the outer surface of the synthetic resin base material formed into a required shape by injection molding technology or the like based on vacuum molding technology or powder slush molding technology, A method for improving the texture is adopted. Further, in order to produce a sense of quality, it is often the case that a specific member such as a wood-grain-like decorative panel component or various accessory components is additionally mounted at a required position on the outer surface of the outer skin.

[0003]

By the way, in the vehicle interior member described above, the work of applying the preformed skin to the base material based on the above-described molding technique and the installation portion provided at a required position of the skin. On the other hand, it is necessary to perform the work of mounting the specific member in separate steps. This is because with the vacuum forming technique or the powder slush forming technique, it was extremely difficult to form the skin and mount the specific member to the formed skin at the same time.

For example, in the powder slush molding, as is well known, the powder slush molding die has two skin molding surfaces.
By heating the mold heated to a high temperature of around 00 ° C. and charged with resin powder such as PVC, TPU, TPO, the resin powder in contact with the heated skin forming surface is appropriately melted and the skin forming surface is This is a technique for forming a skin with a conforming shape.
Therefore, when the specific member made of synthetic resin is set on the skin forming surface that is heated to the temperature described above, the specific member is softened and deformed or melted by this heat, so the specific member is inserted. It can be said that it is almost impossible to form the skin under this condition. Although it is possible to prevent thermal deformation of the specific member by setting the heating temperature of the skin forming surface to a low value, there is a new problem that the melting of the powder resin becomes insufficient and molding defects and quality defects occur. Will occur.

On the other hand, the vacuum forming technique is well known as follows.
This is a technique for forming a skin having a shape along the skin forming surface by suction-adhering a softened resin sheet material heated to a predetermined temperature to the skin forming surface of a vacuum forming mold that is evacuated. . However, when the vacuum forming of the skin is performed under the condition that the specific member is preset on the skin forming surface, the deformation amount (elongation) of the resin sheet material locally increases at the portion corresponding to the specific member. There were inherent problems such as the extremely small thickness of the part and the occurrence of tears.

That is, when using a skin formed by each of the above-mentioned molding techniques, the work of forming the skin and the work of mounting the specific member on the skin are performed in separate steps. There was an inherent problem that the number of steps increased and the molding cost increased. Further, since the specific member is retrofitted from the outside of the outer skin after the outer skin is applied to the base material, a gap is formed at the boundary between the outer skin and the specific member, which rather deteriorates the texture. It was pointed out that there are some drawbacks such as being lost.

[0007]

SUMMARY OF THE INVENTION The present invention has been proposed in order to suitably solve the above-mentioned problems, and is based on the urethane spray molding technology capable of molding at a low temperature, with a specific member set on the molding surface of a molding die. By spraying a urethane material onto the molding surface to mold a urethane film, molding of the urethane film and attachment of a specific member to the urethane film can be performed at the same time to reduce the molding cost and improve the texture. An object is to provide a urethane skin and a molding method for suitably molding the urethane skin.

[0008]

In order to solve the above problems and achieve the intended purpose, the urethane skin according to the present invention requires a urethane film formed by spraying a urethane material onto the molding surface of a mold. It is characterized in that a specific member separately preliminarily formed into a required shape is mounted at a position.

Similarly, in order to solve the above problems and achieve the intended purpose, a method for molding a urethane skin according to another invention is as follows:
On the molding surface of the molding die, set a specific member separately preformed into a required shape, and spray a urethane material on the molding surface on which the specific member is set to form a urethane film having a required thickness. It is characterized in that the molding and the attachment of the specific member to the urethane film are performed simultaneously.

An engaging portion 22 is formed integrally with the side edge portion of the main body 18. Therefore, the decorative panel component 14 is attached to the urethane coating 12 so as not to fall off by the engagement of the engagement concave portion 24 formed on the urethane coating 12 and the engagement convex portion 22 of the component 14. (Fig. 2 (b)). The specific member is not limited to the decorative panel component 14 described above, and various members such as a switch panel and a front garnish of the air outlet are targeted.

FIG. 3 shows a molding die 40 for molding the urethane skin 10 based on the urethane spray molding technique.
FIG. 3 is an explanatory cross-sectional view showing a state where the urethane coating 12 is being molded. The molding die 40 is the same as the urethane skin 10 described above.
Is formed and the surface is textured and the like is provided, and the urethane material 16 sprayed to a required thickness by the spray gun 54 is cured to have a thickness h.
Is designed to mold the urethane film 12 of about 1 mm, and the molding surface 42 is formed on the surface of the molded urethane film 12.
The pattern of can be faithfully reproduced. A heating pipe 44 in which a heat medium such as water or oil flows is laid in a meandering shape on the back side of the molding surface 42, and the surface temperature of the molding surface 42 is set to an optimum temperature (for example, 65) for curing the urethane material 16. (° C)
It can be heated to.

A setting portion 46 for setting the decorative panel component 14 as the specific member is formed at a required position on the molding surface 42 prior to the molding of the urethane film 12. This setting unit 46 is shown in FIG.
And, as shown in FIG. 4, a convex portion 47 having a concave shape matching the front surface shape of the decorative panel component 14 and having an outer edge portion,
A protrusion 47 is provided so that the component 14 can be positioned in an appropriate posture. Further, a plurality of air suction holes 48 are formed in the bottom contact surface of the setting portion 46, and a pipe 52 communicating with an air suction device (adsorption means) 50 is connected to the bottom contact surface. By vacuuming, the decorative panel component 14 can be set in the setting portion 46 in a sucked state. When molding the urethane film 12, as described above, the molding surface 4

Next, a method of molding the urethane skin 10 using the molding die 40 having the above-described structure will be described.

First, as shown in FIG. 4, the decorative panel component 14 separately preformed into a desired shape is set on the molding surface 42 of the molding die 40. At this time, air is sucked from the air suction holes 48 by operating the air suction device 50 to perform vacuuming, whereby the decorative panel component 1
The main body 18 of No. 4 is set to the setting unit 46 in a suction state.
(Figure 5). At this time, the sharp tip ends of the convex portions 47, 47 abut and closely contact along the edge of the main body 18, so that the urethane material 16 is sealed, and the engaging convex portion 22
Is in a state of protruding outward from the convex portion 47.

The decorative panel component 14 for the setting portion 46
Is completed, and the heating medium is supplied to the heating pipe 44 to heat the molding surface 42 to a required temperature, and the urethane material 16 is applied to the molding surface 42 on which the decorative panel component 14 is set by the spray gun 54. By spraying
A urethane film 12 having a thickness h of about 1 mm is formed (FIG. 6). Here, it is desirable that the urethane material 16 is sprayed at least from the engaging convex portion 22 of the decorative panel component 14 to a portion that covers the back surface of the main body 18, so that the engaging convex portion 22 is wrapped with the urethane material 16. Therefore, the urethane film 12 has the engaging projections 22
The engaging recessed portion 24 is formed for engaging with. The urethane material 16 may be sprayed over the entire back surface of the decorative panel component 14.

As the urethane material 16, there are a non-foaming type and a foaming type, etc., which are colored in a required color. As long as they are used as a skin of a vehicle interior member, the non-foaming soft material has excellent durability. Type is preferably used. When the uncolored urethane material 16 is used, it is necessary to spray a urethane paint or the like of a desired color on the molding surface 42 before spraying the urethane material 16.

Since the urethane material 16 sprayed on the surface of the molding surface 42 is heated to the above-mentioned temperature, the curing is accelerated immediately after spraying and the curing is completed in a short time. To do. When the urethane film 12 is cured and the molding is completed, the urethane film 12 and the decorative panel component 14 attached to the urethane film 12 are formed.
The molding is completed by integrally removing the mold from the molding die 40 (FIG. 7).

As described above, the urethane skin 10 molded by using the molding die 40 based on the above-mentioned urethane spray molding technique serves as a specific member when the urethane film 12 constituting the urethane skin 10 is molded. Since the decorative panel component 14 is simultaneously attached to the molded urethane film 12, the decorative panel component 14 can be handled as a single component pre-mounted as described above. Then, as shown in FIG. 8, the molded urethane skin 10 is subjected to an injection molding technique or the like similarly to a conventional general molding skin (a skin formed based on a vacuum molding technique or a powder slush molding technique). It adheres to the outer surface of the base material 30 formed on the basis of the base material to form the decorative surface of the instrument panel 34, which is a vehicle interior member. In addition, in FIG.
The urethane skin 3 of the embodiment, which is foamed and interposed between the urethane skin 10, the base material 30, and both members 10 and 30.
An instrument panel having a three-layer structure including two is illustrated.

In the urethane skin 10 of this embodiment, since the urethane coating 12 is preliminarily attached with the decorative panel component 14, the urethane coating 12 and the decorative panel component 14 are integrally covered on the outer surface of the base material 30. Since it is possible to wear the decorative panel component 14 without the need to separately install the decorative panel component 14 in a later step, the number of man-hours for manufacturing the vehicle interior member such as the instrument panel 34 can be reduced, and the cost can be reduced. Further, since the urethane material 16 is cured while closely adhering to the edge portion of the main body 18 of the decorative panel component 14, it is possible to prevent a gap from being formed at the boundary portion between the decorative panel component 14 and the urethane skin 10. The texture is also improved.

On the other hand, in the urethane skin 10 molded as described above, as another embodiment, as shown in FIG. 10, the molding die (for convenience, referred to as a "first molding die") 40 and a molding paired therewith. By using a mold (for convenience, referred to as a “second molding mold”) 56, the urethane material 36 is formed on the back surface of the urethane film 12.
It is also possible to simultaneously apply the urethane film 12 and the decorative panel component 14 to the urethane base material 38 formed by foaming. That is, when the first molding die 40 is completely closed in the second molding die 56, the cavity 58
The urethane base material 38 molded by foaming and curing the urethane material 36 injected into the back surface of the urethane film 12 in the cavity 58.
A vehicle interior member is simultaneously formed on the outer surface of which the urethane coating 12 with the decorative panel component 14 is attached.

Specifically, as described above and shown in FIGS. 3 to 6, first, in the same manner as in the above-described step, the decorative panel component 1 is attached to the setting portion 46 of the molding surface 42 of the first molding die 40.
4 is set, the urethane material 1 is applied to the molding surface 42.
Spray 6 (Figs. 3 and 6). Next, when the sprayed urethane material 16 is cured and the formation of the urethane film 12 is completed, the urethane injection nozzle (not shown) is used to remove the molded urethane film 12 and the decorative panel part 14 without removing the mold. Liquid reaction type semi-hard type urethane material 36
Is injected on the upper surface of the urethane film 12. Then, when the injection work of the urethane material 36 is completed, the second molding die 56
Is closed from above with respect to the first molding die 40, and the urethane material 3 is held in the cavity 58 defined thereby.
6 is foamed and cured (FIGS. 10 and 11). Then, when the urethane material 36 is foamed and hardened in the cavity 58 to complete the molding of the urethane base material 38, the second molding die 56 is released from the first molding die 40, and the integrated urethane base material 3 is formed.
8, the urethane film 12 and the decorative panel component 14 are released from the first mold 40 (FIG. 12).

The urethane material 36 is classified into the above-mentioned semi-hard type which has appropriate elasticity after curing and the hard type which does not have elasticity after curing, and is selected based on the strength required for the vehicle interior member. Is used for. However, assuming that it is implemented as an instrument panel 34 on which various in-vehicle devices and in-vehicle parts are mounted, since the urethane base material 38 is required to have considerable strength and rigidity, glass fiber or the like is mixed. It is preferable to use the semi-rigid urethane material 36 described above.

As described above, in the urethane skin 10 of the embodiment, if the molding dies 40 and 56 are used based on the urethane spray molding technique described above, the decorative panel component 14 is mounted on the molding surface 42 of the molding die 40. Urethane film 12
After molding, it may be possible to mold the urethane base material 38 on the back surface of the decorative panel component 14 and the urethane coating 12.

Although not specifically shown, when molding the urethane base material 38 on the back surface of the urethane coating 12 using the molding dies 40 and 56 shown in FIG. 10, a material such as PP separately injection-molded is used. If a hard base material is set on the molding surface of the second molding die 56, the urethane base material 38 is molded with the urethane coating 12 of the base material. This makes it possible to mold a so-called three-layer type vehicle interior member including the base material, the urethane base material 38, and the urethane skin 10.

FIGS. 13 to 19 show a modification of the setting mode of the decorative panel component 14 as a specific member with respect to the setting portion 46 of the molding die 40 and other examples, and the respective sets shown here. Even if the embodiment example is adopted, the decorative panel component 14 can be suitably set and held in the setting portion 46. Of these, FIG. 13 shows a modified example of the setting mode shown in FIG. 4, in which a supporting piece 26 formed of foamed rubber or the like and elastically deformable is provided on the contact surface of the setting portion 46 with the air suction hole. The ring 48 is additionally arranged in a ring shape. The supporting piece 26 is always projected from the contact surface of the setting portion 46 by a required amount (about 0.5 to 1 mm), and can be compressed and deformed to the same level as the contact surface when pressed from above. Has become.

As a result, when the decorative panel component 14 is set in the setting portion 46 while the air suction device 50 is operated to evacuate, the main body 18 of the component 14 is first placed on the top surface of the support piece 26. Come into contact
(FIG. 14 (a)), the decorative panel component 14 is set by the set portion 46.
Before contacting the contact surface, the air in the vacuum area 28 defined by the support piece 26, the main body 18, and the contact surface is sucked at once. As a result, the decorative panel component 14 is strongly attracted to the setting portion 46 due to the compressive deformation of the support piece 26 and is set in the suction state, and the close contact with the convex portions 47, 47 is enhanced, and the urethane material 1
The sealability with respect to 6 is improved (FIG. 14 (b)).

FIG. 15 exemplifies a setting mode according to another example. An opening 60 is formed in the contact surface of the setting section 46, and a suction cup type suction member (suction means) 62 is provided in the opening section 6.
The adsorbing member 62 is used to set the decorative panel component 14 in the adsorbed state so as to face 0. The suction member 62 has a vacuum specification so that air on the front surface of the suction member 62 is supported by the support shaft 64.
While being able to be suctioned through the inside of
It is configured so that it can be moved up and down so as to appear in and out of the setting portion 46 through the opening 60.

As a result, the suction member 62 is attached to the setting portion 46.
In a state in which it is stopped at a position appropriately elevated from the contact surface of, and the air suction device (not shown) is activated to perform vacuuming,
When the decorative panel component 14 is brought close to the setting portion 46, the main body 18 of the decorative panel component 14 firstly receives the suction member 62.
, So that the component 14 is attracted to the attracting member 62 (FIG. 16 (a)). Next, by moving the suction member 62 downward, the decorative panel component 14 suction-held by the suction member 62 is attracted to the contact surface of the set portion 46 and closely adheres to the convex portions 47, 47. As a result, the sealing property with respect to the urethane material 16 is improved.
(FIG.16 (b)).

FIG. 17 exemplifies a setting mode according to still another example, in which a pressing member (pressing means) 66 having an appropriate weight and capable of being placed on the decorative panel part 14 is used to mount the part 14. It is adapted to be set in the setting section 46 in the pressed state. The pressing member 66 is formed in a size slightly smaller than the decorative panel component 14,
It is set so as to be located inside the engaging convex portion 22 in a state of being placed so as to come into contact with the engaging convex portion 22.
(FIG.17 (b)).

In such a setting mode, the setting section 46
With the decorative panel component 14 set in (
(a)) The pressing member 66 is placed on the decorative panel component 14. As a result, the decorative panel component 14 is set in a state of being pressed against the setting portion 46 by the weight of the pressing member 66, the close contact with the convex portions 47, 47 is enhanced, and the sealing property with respect to the urethane material 16 is improved ( FIG. 17 (b)).
Then, when the setting of the decorative panel component 14 to the setting portion 46 by the pressing member 66 is completed, the urethane material 16 is sprayed onto the molding surface 42 on which the decorative panel component 14 is set by the spray gun 54 to mold the urethane film 12. (Figure 18). As described above, since the engaging convex portion 22 of the decorative panel component 14 projects outward from the pressing member 66, the urethane material 16 is cured so as to wrap the engaging convex portion 22, and Engagement concave portion 2 engaging with the convex portion 22
4 is formed. The urethane material 16 is used for the pressing member 6
It is desirable to spray so as not to hit 6.

When the urethane material 16 is completely cured and the urethane film 12 is formed, the pressing member 66 is pressed.

Regarding the set portion 46 provided with the convex portions 47, 47, as shown in FIG. 17A, when the decorative panel component 14 is set in the set portion 46, the decorative panel component 14 A slight gap 68 may be defined between the main body 18 and the contact surface of the setting portion 46. As a result, when the decorative panel component 14 is set in the setting portion 46, the top surfaces of the convex portions 47, 47 are appropriately brought into close contact with the component 14 to improve the sealing property, and the urethane material 16 is The protrusion to the front side of the main body can be suitably prevented. Setting the setting portion 46 so that the gap 68 is defined in this manner can be applied to each of the above-described setting modes.

Further, in the setting mode shown in FIGS. 4, 13 and 15, the decorative panel component 14 is set to the setting portion 46 in a sucked state, so that, for example, a steep slope portion of the molding surface 42 is set. Even if the setting portion 46 comes to be located at the position (not specifically shown), the decorative panel component 14 can be appropriately set and held prior to the molding of the urethane coating 12.

The urethane skin 10 molded by the molding method of this embodiment is not limited to the one used for the instrument panel 34, but may be used as a skin for a floor console, a door panel, or other various vehicle interior members. It is possible.
