It has a triangular shape. In short, the anchor projection 7 may be any function as long as it has a function capable of being engaged with the recess 3 for attaching the trim component, and the cross-sectional shape may be semicircular or circular.
[0024]
On the other hand, the instrument panel 1 includes a two-layer laminate sheet 13 composed of a skin layer 11 and a foam layer 12 as shown in FIG. 3, and a skin layer 11 and a foam layer 12 as shown in FIG. A multi-layer skin (which may be a single-layer skin, hereinafter referred to as skin 16) and a core, such as a three-layer laminate sheet 15 to which a layer 14 (or a backer layer, a heat-sealing layer, or the like) is added It is constituted by the material 17. As the core material 17, a PP material, a PP composite material, an ABS material, a PC material, a PPE material, a PC / ABS material, an AS material, or a synthetic resin material in which a glass filler is mixed therein is used. Alternatively, the core material 17 is made of a wood material obtained by compressing and curing a wood filler or wood chip, or a wood material obtained by compressing and hardening a wood filler or wood chip with a powder and a liquid adhesive. .
[0025]
And this instrument panel 1 is formed by vacuum forming (vacuum convex drawing). FIG. 5 shows the vacuum forming means 18 of the instrument panel 1. The vacuum forming means 18 is a vacuum such as a core type connected to a vacuum source 21 such as a vacuum tank via an exhaust passage 19 and an on-off valve 20. A mold 22 and a skin clamp 24 that holds the skin 16 with respect to a mold surface 23 (convex surface) of the vacuum mold 22 are provided. The core material 17 is disposed between the mold surface 23 and the skin 16. A large number of vacuum holes 25 are formed in the core member 17, and a number of vacuum manifolds (not shown) are formed inside the vacuum mold 22. Reference numeral 67 is a vacuum table, and 68 is a sealing material.
[0026]
The vacuum forming means 18 of the instrument panel 1 is provided with a recess forming means 26 for forming the recess 3 for attaching the trim parts. The recess forming means 26 includes a plug assist 28 disposed so as to be movable toward and away from the recessed portion 27 formed on the mold surface 23 of the vacuum die 22, and the plug assist 28 is brought close to the recessed portion 27. A moving means 29 such as a cylinder (air cylinder, hydraulic cylinder) to be moved away from each other and a plug assist holding device 31 for detachably holding the plug assist 28 at the tip of the rod 30 of the moving means 29 are configured. The plug assist holding device 31 is, for example, a vacuum clamp 33 connected to a vacuum source (not shown) (the vacuum source 21 may be used) via a suction pipe 32.
[0027]
In the first embodiment, in particular, as the plug assist 28, the trim component 4 provided with the anchor projection 7 on the outer periphery is directly used.
[0028]
An opening 34 for separating trim parts is formed in advance at a position corresponding to the concave portion 27 of the core member 17.
[0029]
Next, the operation of the first embodiment will be described.
[0030]
A vacuum source 21 such as a vacuum tank is driven in an exhaust flow path in a state where the core 17 and the skin 16 are placed in contact with each other on the mold surface 23 of the vacuum mold 22 and the skin 16 is held by the skin clamp 24. By vacuuming the inside of the vacuum mold 22 via the 19 and the on-off valve 20, the instrument panel 1 is vacuum formed. At this time, by forming a large number of vacuum holes 25 in the core material 17, a suction force acts on the skin 16, and the core material 17 and the skin 16 are simultaneously and integrally formed.
[0031]
And in the part of the concave-shaped part 27 formed in the mold surface 23 of the vacuum mold 22, the core material 17 and the skin 16 enter into the concave-shaped part 27 by vacuum suction. At this time, the moving means 29 such as a cylinder By extending the rod 30 and pressing the plug assist 28 adsorbed by the plug assist holding device 31 at the tip of the rod 30 against the concave portion 27, the core material 17 and the skin 16 in the concave portion 27 are plug-assist. 28, the recess 3 for attaching trim parts is accurately formed.
[0032]
In the first embodiment, in particular, since the trim part 4 is directly used as the plug assist 28, it is not necessary to prepare the plug assist 28 specially, and the plug assist holding device 31 is released, so that The trim part 4 can be embedded in the recess 3 for attaching the trim part integrally, and it is not necessary to bond it with screws, adhesives or double-sided tape. It is possible to go down.
[0033]
In addition, when the vehicle is scrapped, separation and disassembly are facilitated. In particular, when the material of the skin 16 and the trim component 4 is the same or mixed, it can be crushed as it is without disassembly.
[0034]
Further, when the trim part 4 is detached and disassembled, the trim part 4 is easily separated by forming an opening 34 for separating the trim parts at a position corresponding to the concave portion 27 of the core member 17. Can be removed. Further, the trim part 4 that has been removed can be reused as it is.
[0035]
  Moreover, the trim part 4 is directly used as the plug assist 28.At the same time, the trim part 4 is embedded in the formed recess 3 as it is.BySince there is no need to design for manufacturing errors,The mounting accuracy of the trim component mounting recess 3 is improved, and the design is in a so-called all-round zero gap and no plane difference state, that is, the periphery of the trim component body 5 and the trim component mounting recess 3. The gap between the peripheral portion and the peripheral portion between the surface of the trim component body 5 and the surface of the instrument panel 1 is a so-called all-round zero gap state in which the clearance between the peripheral portion and the design panel is zero. Thus, a so-called zero surface difference state (hereinafter the same) can be achieved.As described above, in the case of manufacturing with the design that the clearance is zero on the entire circumference and the surface difference is zero, the forming ability of the vacuum forming means 18 can be maximized. However, even in this case, it is impossible to exceed the forming capability of the vacuum forming means 18 alone, so that the accuracy of mounting the trim part 4 to the concave portion 3 that can be actually obtained is the vacuum forming means. The limit is the molding accuracy that can produce 18.
[0036]
In addition, by providing the anchor projection 7 on the outer periphery of the trim component 4, the trim component 4 can be firmly fitted and fixed to the recess 3 for attaching the trim component. At this time, the shape of each anchor projection 7 is a triangular shape having a locking top portion 8, a wedge surface 9, and a biting surface 10. Since it becomes easy to enter and it becomes difficult to come out from the recessed part 3 for trim components attachment by the biting surface 10, much bigger fixing force can be obtained.
[0037]
In addition, by using the vacuum clamp 33 as the plug assist holding device 31, the trim component 4 can be sucked and held without being damaged, and the trim component 4 embedded in the recess 3 for attaching the trim component can be released by suction. , Easy to handle.
[0038]
[Modification]
7 and 8 show modifications of the first embodiment, and show an example in which the instrument panel 1 is manufactured by vacuum forming (vacuum recessing) and injection molding (or injection press molding).
[0039]
That is, as shown in FIG. 7, the skin 16 is recessed by using a vacuum mold 42 such as a cavity mold having a concave mold surface 41 as the vacuum forming means 18. At this time, the plug assist 28 (trim component 4) of the recess forming means 26, the moving means 29, and the plug assist holding device 31 are accommodated in the concave portion 27, and the plug assist 28 is pushed out, thereby attaching the trim component. At the same time as forming the recess 3, the trim component 4 is integrally embedded in the recess 3 for attaching the trim component.
[0040]
In FIG. 7, reference numeral 43 denotes a vacuum manifold formed in the vacuum mold 42, and reference numeral 44 denotes an on-off valve provided in the middle of the suction pipe 32.
[0041]
As shown in FIG. 8, the skin 16 molded in the injection molds 46 and 47 of the injection molding device 45 is set, and the core material 17 is injection-molded on the back side of the skin 16.
[0042]
Even if it does in this way, the effect similar to the said Embodiment 1 can be acquired.
[0043]
Second Embodiment of the Invention
9 and 10 show the second embodiment of the present invention. The same or equivalent parts as those in the first embodiment will be described with the same reference numerals.
[0044]
In the second embodiment, the trim component body 5 of the trim component 4 having the anchor projections 7 formed on the outer periphery is composed of a light transmitting non-translucent layer 51 on the back surface side and a semi-transparent layer 52 on the front surface side. The light source 53 is disposed on the back side of the trim component body 5 with a two-layer structure.
[0045]
The light transmission type non-translucent layer 51 has a light-colored color that transmits light such as white, light green, and light pink, and is not translucent or transparent.
[0046]
The translucent layer 52 has a display part a such as a logo indicating a car name or equipment drawn on the surface by printing or unevenness.
[0047]
Such a trim component body 5 is manufactured by two-color, two-layer, or different material molding including insert molding.
[0048]
As the light source 53, for example, as shown in FIG. 10, an illumination circuit in which a bulb 54 is connected to a power source 55 and a switch 56 is used. Alternatively, as shown in FIG. 11, an illumination circuit in which the LED 57 is connected to a power source 55 and a switch 56 is used.
[0049]
Thus, by making the surface side the translucent layer 52, a transparent display part a can be made, and when the light source 53 emits light at night or the like, the translucent non-translucent layer 51 and the translucent layer The display part a floats through the layer 52, and the display part a can be illuminated.
[0050]
Further, by making the rear surface side of the trim component body 5 the light transmission type non-translucent layer 51, the mounting portion 6 is not seen from the outside even when the front surface side of the trim component body 5 is the semitransparent layer 52. Can be hidden.
[0051]
Except for the above, the configuration is the same as that of the first embodiment, and the same actions and effects can be obtained.
[0052]
[Modification]
FIG. 12 shows a first modification of the second embodiment, in which a boss 58 and a rib 59 for screwing are provided on the back surface side of the light transmission type non-translucent layer 51 as a mounting portion 6. It is. In this way, by setting the rear surface side of the trim component body 5 as the light transmission type non-translucent layer 51, even when the front surface side of the trim component body 5 is the translucent layer 52, The rib 59 can be hidden from view from the outside.
[0053]
Embodiment 3 of the Invention
13 to 20 show a third embodiment of the present invention. The same or equivalent parts as those in the first and second embodiments will be described with the same reference numerals. First, the configuration will be described. The feature of the third embodiment is that a heat-foamable additive 71 is blended in at least one of the skin 16 and the core member 17 or on the adhesive surface between them.
[0054]
Specifically, for example, when the skin 16 is a single layer, even if the heat-foamable additive 71 is blended inside the skin layer 11 as shown in FIG. Thus, you may mix | blend the heat-foamable additive 71 with the adhesive surface of the skin layer 11. FIG. Further, when the skin 16 has two layers, even if the thermally foamable additive 71 is blended at the boundary between the foam layer 12 and the skin layer 11 as shown in FIG. As shown in FIG. 14, even if the heat-foamable additive 71 is blended in the foam layer 12, the heat-foamable additive 71 is blended on the adhesive surface of the foam layer 12 as shown in FIG. Also good. When the skin 16 has three layers, even if the thermally foamable additive 71 is blended at the boundary between the barrier layer 14 and the foam layer 12 as shown in FIG. 15 (a), it is shown in FIG. 15 (b). Thus, even if the thermally foamable additive 71 is blended inside the barrier layer 14, the thermally foamable additive 71 may be blended on the adhesive surface of the barrier layer 14 as shown in FIG.
[0055]
Then, as shown in FIG. 16, the skin 16 is heated in a heating device including an upper heater 71 and a lower heater 72, and as shown in FIG. 17, the core material 17 is made of a vacuum mold 22 such as a core mold. Above, heating is performed partially or entirely by a heating device such as a flexible heater 73. As a heating device, it is preferable to use a flexible heater 73 that can be changed into a three-dimensional shape by a flexible rod with tension and can easily bring out the shape of the core material 17. Alternatively, the heating device for the core material 17 may be a dryer-type hot air heater such as a gas burner 74 as shown in FIG. 18 or a core material-shaped heating die 75 as shown in FIG. .
[0056]
When the skin 16 and the core material 17 are heated, the skin 16 is disposed on the core material 17 on the vacuum mold 22 such as the core mold, and the recess forming means 26 and the cavity are formed thereon as shown in FIG. A vacuum mold 42 such as a mold is set and vacuum formed.
[0057]
  Thereby, the skin 16 and the core material 17 are shaped and welded. At this time, the heat-foamable additive 71 is blended in at least one of the inner surface of the skin 16 and the core material 17 or the mutual adhesive surface, and the skin 16 and the core material 17 are heated and vacuum-formed. Then, the heat-foamable additive 71 expands, and the gap between the peripheral edge of the plug assist 28 (trim component 4) and the peripheral edge of the recess 3 for attaching the trim component is narrower and tighter over the entire periphery. It is possible to further stabilize the state of the design so-called zero-round perimeter and zero-surface difference.That is, the tightness of the gap due to the expansion of the heat-foaming additive is added, so that it is theoretically possible to exceed the forming capability of the vacuum forming means 18. It can be expected that the mounting accuracy is higher than the molding accuracy that the vacuum forming means 18 can produce. However, to what extent the mounting accuracy of the trim part 4 to the recess 3 can be increased depends on the magnitude of the expansion force of the thermally foamable additive.
[0058]
In addition, since the expansion rate and expansion rate of the foam layer 12 can be increased by the expansion of the heat-foamable additive 71, variations in the finish of the portion where the expansion rate and expansion rate are large can be reduced. .
[0059]
Other than the above, the same configuration as in the first and second embodiments is provided, and the same actions and effects can be obtained.
[0060]
【The invention's effect】
  As described above, according to the invention of claim 1,It is directly used as a plug assist for pressing and forming a recess for attaching a trim component, and a trim component main body that is embedded as it is in the formed recess is provided and embedded in the recess.On the outer periphery of the trim body, Can be locked to the recessBy providing the anchor projection, the trim component can be firmly fixed to the concave portion of the instrument panel portion.
[0061]
  According to the invention of claim 2,A trim component body that is directly used as a plug assist that presses and forms a recess for attaching a trim component, and that is provided with a trim component body that is embedded in the recess as it is, is embedded in the recess.By making the surface side of the transparent layer a translucent layer, a transparent display unit can be made, and when the light source emits light at night or the like, the display unit passes through the light transmissive non-translucent layer and the translucent layer. It can be lifted and the display can be illuminated.
[0062]
Further, by making the rear surface side of the trim component main body a light transmission type non-translucent layer, even when the front surface side of the trim component main body is a translucent layer, the mounting portion can be hidden from view from the outside.
[0063]
  According to the invention of claim 3, as the plug assist,Trim component body with anchor projections on the outer peripheryIs used directly, so there is no need to prepare special plug assist andPressingTrim parts as they are when formedBodyCan be integrally embedded in the recess, and it is not necessary to bond with a screw stopper, an adhesive, or a double-sided tape, so that it is possible to reduce assembly man-hours and labor and reduce costs. In addition, sorting and dismantling is easy even when the vehicle is scrapped.
[0064]
  Moreover, as a plug assist, a trim component body having an anchor protrusion formed on the outer periphery is directly used.At the same time, the trim part body is embedded in the formed recess.BySince there is no need to design for manufacturing errors,The mounting accuracy to the recess is improved, and a so-called design of a so-called all-round zero gap and zero surface difference can be achieved.Here, the so-called all-round zero gap and zero surface difference in terms of design means that the gap between the peripheral edge of the trim component main body and the peripheral edge of the recess for attaching the trim component extends over the entire circumference. Manufacture with a design value of 0 (so-called zero clearance around the entire circumference) and a surface difference between the peripheral edges of the surface of the trim part body and the surface of the instrument panel portion with a design value of 0 ( So-called surface difference of 0). As described above, when the product is manufactured with the design that the entire circumference is 0 gap and the surface difference is 0, the forming ability of the vacuum forming means can be maximized. However, even in this case, it is not possible to exceed the forming capability of the vacuum forming means by itself, so the accuracy of mounting the trim part main body to the recess as described above can be obtained by the vacuum forming means. Up to molding accuracy is the limit.
[0065]
  According to invention of Claim 4, a thermal foaming additive is mix | blended with the said instrument panel part, a thermal foaming additive expand | swells by heating and vacuum-molding an instrument panel part, Plug assist ( The clearance between the peripheral edge of the trim part) and the peripheral edge of the recess for attaching the trim part can be made narrower and tighter over the entire circumference. The state where the surface difference is zero can be further stabilized.In other words, the tightness of the gap due to the expansion of the heat-foaming additive can theoretically exceed the forming capacity of the vacuum forming means, so that the trim part body can be attached to the recess. It can be expected that the accuracy is higher than the molding accuracy that the vacuum forming means can produce. However, to what extent the mounting accuracy of the trim component main body to the recess can be increased depends on the magnitude of the expansion force of the thermally foamable additive.
[0066]
In addition, the expansion rate and expansion rate of the foam part can be increased by the expansion of the heat-foamable additive, so the variation in the finish of the instrument panel part and the location where the expansion rate is large should be reduced. Can produce a practically beneficial effect.
