Description

  The present invention relates to a method for molding a vehicle interior product and an apparatus for molding a vehicle interior product, and more particularly, a method for molding a vehicle interior product in which a skin is molded and bonded to the surface of a curved base material, and the molding thereof. It relates to the device.

  For example, an instrument panel is generally attached to a position facing a driver seat and a passenger seat along the windshield of an automobile as an interior part of a vehicle, and extends in the vehicle width direction as a longitudinal direction. That is, the vehicle has a curved cross section in the front-rear direction.

  Such an instrument panel is formed by molding and joining an outer skin to a vehicle interior surface of a base material having a curved cross section so as to form a basic shape thereof. Here, FIG. 6 is shown in order to explain the conventional general technique of a molding apparatus for interior parts of a vehicle for molding and joining the base material K and the skin H, and the skin holding means 1 for holding the skin H. The surface of the molded part 20 ′ of the skin mold 2 ′ is obtained by replacing the skin mold 2 ′ having a molded part 20 ′ whose surface has a shape corresponding to the surface shape of the interior product and the skin H held by the skin holding means 1 ′. Adsorption means 3 'for adsorbing to the substrate, a substrate mold 4' for holding the substrate K, and a heating means 5 'for softening the skin H. In the form shown in FIG. 6, the skin holding means 1 ′ is configured to hold the skin H horizontally, and the skin mold 2 ′ is arranged above the base material mold 4 ′ and is made up and down of a hydraulic cylinder or the like. It can be moved up and down by means 15 '. Therefore, the relative movement direction (mold opening / closing direction) between the base material mold 4 ′ and the skin mold 2 ′ is the vertical direction in FIG. 6.

  The base material mold 4 ′ is formed in a convex shape so as to have a top near the center in the cross section (left and right direction in FIG. 6), and the holding portion 40 ′ corresponding to the cross-sectional base material K curved on the surface thereof. Is configured. The base portion 41 ′ of the base mold 4 ′ is disposed so as to be substantially horizontal and orthogonal to the skin H so as to be orthogonal to the mold opening / closing direction. The skin mold 2 ′ is formed in a concave shape so as to have a bottom near the center in the cross section (left and right direction in FIG. 6), and the surface according to the shape of the inner surface of the interior of the automobile to be molded inside Is formed. When adsorbing the skin H of the skin mold 2 ′, the lower edge (seal line) 20a ′ in contact with the skin H at the beginning of the skin mold 2 ′ is substantially parallel to the skin H held horizontally by the skin holding means 1 ′. Moreover, it is formed substantially horizontally so as to be orthogonal to the mold opening / closing direction (vertical direction) of the skin mold 2 ′. The base portion 21 ′ of the skin mold 2 ′ is also disposed so as to be substantially horizontal so as to be orthogonal to the mold opening / closing direction and to extend substantially parallel to the seal line 20 a ′ and the skin H. Further, the skin mold 2 ′ has a space 22 ′ therein, and a ventilation hole 23 ′ that communicates the space 22 ′ and the surface of the molding portion 20 ′ is formed. The space 22 'of the skin mold 2' is connected to a suction means 3 'for sucking the skin H through the air holes 23' and sucking it onto the surface of the molding portion 20 '.

  Further, the molding apparatus holds the skin holding means 1 ′, an adsorption position A ′ between the skin mold 2 ′ and the base material mold 4 ′ for adsorbing the skin H to the skin mold 2 ′, and the skin H holding the skin H. Conveying means 6 ′ for conveying the set position B ′ held by the means 1 ′ and the heating position C ′ for heating and softening the skin H by the heating means 5 ′ are provided.

  In the molding apparatus configured as described above, the base material K is set and held on the surface of the holding portion 40 ′ of the base material mold 4 ′, and the skin H is horizontally placed on the skin holding means 1 ′ at the set position B ′. The skin holding means 1 ′ is transported horizontally by the transport means 6 ′ to the heating position C ′ of the heating means 5 ′, the skin H is heated to a predetermined temperature and softened, and then the transport means 6 ′. The skin holding means 1 'is transported horizontally to the suction position A' between the skin mold 2 'and the base mold 4', the elevating means 15 'is extended to drive the skin mold 2' down, and the skin Approach H. At this time, the suction means 3 'is driven and the space 22' inside the skin mold 2 'is in a decompressed state, and the softened skin H is released from being held by the skin holding means 1'. It is adsorbed on the surface of the molded part 20 ′.

  In this state, the pressurizing means 9 ′ composed of a hydraulic cylinder or the like is driven to extend to raise the base material mold 4 ′, and the base material K held by the base material mold 4 ′ is softened to the skin mold 2 ′. The adsorbed skin H is pressed and bonded between the surface of the holding portion 40 ′ and the surface of the molding portion 20 ′.

  Here, when the skin H held horizontally by the skin holding means 1 ′ is adsorbed to the surface of the molding part 20 ′ of the skin mold 2 ′, the conventional technique shown in FIG. 6 uses the molding part of the skin mold 2 ′. Since the surface of 20 'was formed in a concave shape having a bottom near the approximate center in the cross section, the amount of elongation of the portion adsorbed to the bottom of the skin H is large, and the amount of elongation decreases as it approaches the edge (see FIG. (See the length of the arrow shown in FIG. 6). As a result of the uneven elongation amount of the skin H, there arises a problem that the skin H cannot be formed to a desired thickness.

  Therefore, Patent Document 1 is known as a conventional technique for solving such problems. In Patent Document 1, an injection-molded base material is set in a base-material-side vacuum suction mold, and the base-material-side vacuum suction mold and the skin-side vacuum suction mold are clamped in advance, so In a state where the side vacuum suction molds are separated from each other, the skin disposed between the vacuum suction molds in a planar shape and having a peripheral edge fixed by a clamp is brought into contact with the base material, and the inner surface of the skin side vacuum suction molds In this state, the skin is vacuum-sucked by the skin-side vacuum suction mold, and the skin is formed. Next, after the vacuum suction by the skin-side vacuum suction mold is stopped, the substrate is aerated by the base-side vacuum suction mold. In the vacuum forming method of the interior product in which the skin is vacuum-sucked to the substrate side through the part and the skin is bonded to the substrate, the skin is clamped between the substrate-side vacuum suction mold and the skin-side vacuum suction mold The amount of interference with both vacuum suction type is small, and the amount of interference Interiors vacuum forming method, wherein like tilting hold the skin to angle the balance is disclosed in countercurrent.

  FIG. 7 shows a specific example of a molding apparatus for applying the technique disclosed in Patent Document 1, and the base portion 41 ″ of the base material mold 4 ″ extends in a direction perpendicular to the mold opening / closing direction. The surface of the holding portion 40 ″ is formed in a cross-sectional shape inclined with respect to the base portion 41 ″ so that the left direction in FIG. The "base portion 21" is arranged so as to extend in a direction perpendicular to the mold opening / closing direction, and the surface of the molding portion 20 "has a large amount of protrusion downward in the left direction in FIG. It is formed in a cross-sectional shape that is inclined with respect to the base portion 21 ″ so that the protruding amount is small. Accordingly, the seal line 20a ″ of the skin mold 2 ″ is also inclined with respect to the direction orthogonal to the mold opening / closing direction (in FIG. 7, since the mold opening / closing direction is the vertical direction, the orthogonal direction is the horizontal direction). ing. The skin holding means 1 ″ for holding the skin H is supported so as to be able to be raised or lowered by a shaft 1a ″ with respect to the conveying means 6 ″.

  In the molding apparatus configured as described above, when the skin H is held horizontally at the set position B ″, when the skin is heated to a predetermined temperature and softened at the heating position C ″, each position A ″, B When transported to ", C", the posture of the skin holding means 1 "is held horizontally. On the other hand, when the skin H is attracted to the skin mold 2 ″ at the suction position A ″, as shown in FIG. 7, the shaft 1a ″ is made to correspond to the inclination of the seal line 20a ″ with respect to the horizontal of the skin mold 2 ″. The posture of the epidermis holding means 1 "is raised or turned around the center. Accordingly, when the base mold 4 ″ and the skin mold 2 ″ are clamped or when the skin H is adsorbed to the skin mold 2 ″, the interference amount of the skin H with the base mold 4 ″ and the skin mold 2 ″ is reduced. And the amount of interference is balanced in the front-rear and left-right directions, and as a result, the skin H is held at an angle so that the stretch amount of the skin H (see the length of the arrow shown in FIG. 7) does not deviate from part to part. be able to.

  However, in Patent Document 1, the skin holding means 1 "holding the skin H is maintained in a horizontal position while the conveying means 6" uses the heating means 5 "to the skin mold 2" and the substrate mold 4 ". Then, as shown in FIG. 7, the posture of the skin holding means 1 ″ is centered on the shaft 1a ″ and the seal line 20a with respect to the horizontal of the skin mold 2 ″ is moved. It is necessary to raise or lower the skin mold 2 "so as to be parallel to the inclination of" "and to lower the skin mold 2" and attract it to the surface of the molding part 20 "of the skin mold 2" by the suction means 3 ". Therefore, the posture of the skin holding means 1 ″ holding the skin H softened by the heating means 5 ″ is inclined from the state in which the skin holding means 1 ″ is held horizontally to the seal line 20a ″ of the skin mold 2 ″ around the axis 1a ″. There is a problem in that the elevation and rotation of the skin holding means 1 ″ is required to be performed and the mechanism and control for the elevation and rotation are required. It is difficult to shorten the molding cycle time because the operation time is required to move, and furthermore, the skin H is adsorbed on the surface of the molding part 20 ″ of the skin mold 2 ″ to be molded and bonded to the base material K.

Next, an embodiment of a method for molding an interior product for a vehicle according to the present invention will be described together with the operation of the molding apparatus configured as described above.
The method for molding an interior product N of a vehicle according to the present invention includes a molded part of a skin mold 2 having a shape corresponding to the surface shape of the interior product N while holding the base material K in a substantially curved shape. The skin H is adsorbed on the surface of 20, the base material mold 4 and the skin mold 2 are moved relatively close to each other, the mold is closed, and the base material K and the skin H are pressurized and joined. The skin mold 2 is held in a relative posture with respect to the skin H in such a relationship that the amount of elongation of the skin H from the state before the H is adsorbed to the surface of the molding part 20 of the skin mold 2 is averaged. In addition, the skin H is adsorbed to the surface of the molding part 20 of the skin mold 2.

  The skin H is held substantially horizontally by the skin holding means 1 at the suction position A, and the base portion 21 of the skin mold 2 is supported by an inclined base 25 having a predetermined angle, so that the seal line 20a of the molding portion 20 is obtained. Is substantially horizontal, and as described above, the seal line 20a of the skin mold 2 is held in parallel with the skin H held substantially horizontally at the suction position A.

  When molding the vehicle interior goods N, first, the base material mold 4 is raised, and the skin holding means 1 is arranged at the set position B (FIG. 2) by the conveying means 6. In this state, the skin holding means 1 is held by the skin holding means 1 so as to be substantially horizontal, and the skin holding means 1 is moved horizontally to the suction position A by the transport means 6. Further, the base material K is held by the holding portion 40 of the base material mold 4. The setting of the base material K with respect to the base material mold 4 may be performed manually by the worker M, or may be mechanically performed by a robot or the like. At this time, in this embodiment, when the base material K is set on the base material mold 4, the surface of the holding portion 40 faces upward, so that the worker M manually moves the base material K to the base material mold 4. Can be set easily. Also, when the base material K is mechanically set on the base material mold 4 by a robot or the like, the control of the robot or the like becomes easy.

  Next, in this embodiment, the heating means 5 is moved to the adsorption position A between the base material mold 4 and the skin mold 2 (see arrow T in FIG. 1), and the skin H is heated to a predetermined temperature. After that, the heating means 5 is retracted to a position C that is out of the space between the base material mold 4 and the skin mold 2 (see arrow T in FIG. 1). Further, when the heating means 5 is fixed at a position C deviated from between the base material mold 4 and the skin mold 2, the skin holding means 1 is moved horizontally to the position C by the transport means 6, and the skin H is moved to a predetermined level. The skin holding means 1 is moved horizontally to the suction position A after heating to temperature and softening. Then, the skin holding means 1 is moved downward by the conveying means 6 (see arrow S in FIG. 1), the skin H is brought into contact with the seal line 20a of the skin mold 2, and the motor 30 of the suction means 3 is driven. Then, the space 22 in the molding part 20 is decompressed by the vacuum pump 31, so that the skin H is adsorbed on the surface of the molding part 20 through the air holes 23.

  At this time, even if the seal line 20a of the molding part 20 is inclined with respect to the base part 21 of the skin mold 2, the skin line is formed so that the seal line 20a and the skin H held substantially horizontal are parallel to each other. The two base portions 21 are supported by the tilt table 25 in a tilted state. Therefore, the skin H is averaged so that the difference in the amount of elongation of the skin H from the state in which the skin H is in contact with the seal line 20a to the surface of the molded part 20 becomes small. As a result, the thickness of the skin H Will be made uniform.

  Furthermore, in this embodiment, after the skin H is heated at the suction position A by the heating means 5, the heating means 5 is simply retracted to a position C that is out of the space between the base material mold 4 and the skin mold 2. There is no need to rotate or lift the posture of the skin holding means 1 as in the prior art (FIG. 7). Therefore, the skin H can be adsorbed to the skin mold 2 in a short time after the heating is completed simply by moving the skin holding means 1 downward so as to approach the skin mold 2. The heating means 5 is fixed at a position C away from between the base material mold 4 and the skin mold 2, and the transport means 6 is moved so that the skin holding means 1 can be moved horizontally to the position of the heating means 5. Even in the case of the configuration, after the skin H is heated to a predetermined temperature by the heating means 5, the skin holding means 1 is moved horizontally from the heating means 5 to the suction position A by the transport means 6 and is lowered so as to approach the skin mold 2. Since it is only moved, the skin H can be adsorbed to the skin mold 2 in a short time after the heating is completed.

  When the skin H is adsorbed to the molding portion 20 of the skin mold 2, the base material mold 4 moves downward as indicated by a chain line R in FIG. The mold is closed and clamped with a predetermined force. Thereby, the base material K and the skin H are pressurized and joined between the holding part 40 of the base material mold 4 and the molding part 20 of the skin mold 2. At this time, as described above, the elongation amount of the skin H when the skin H is adsorbed to the skin mold 2 is averaged, so that the thickness of the skin H is made uniform. Since the posture of the skin mold 2 with respect to the skin H is maintained in such a relationship as to average, the posture of the skin H is not changed, so that the molding cycle time can be shortened. Since the base material K can be formed and joined before the temperature of the skin H is lowered, a high-quality vehicle interior product N can be easily and reliably formed.

Next, a second embodiment of the apparatus for molding a vehicle interior product N according to the present invention will be described with reference to FIGS. Note that the same or corresponding components as those in the first embodiment described above are denoted by the same reference numerals, description thereof is omitted, and only different components are described.
The molding apparatus in this embodiment includes a mold posture changing means 7 that changes the posture of the skin mold 2 and a clamp means 8 that holds the base mold 4 that is closed with respect to the skin mold 2.

  The skin mold 2 in this embodiment is supported by a movable platen 26 that can be lifted by pivoting one side edge. A piston rod of a hydraulic cylinder 70 is connected to the movable plate 26 as the mold posture changing means 7. Further, between the movable platen 26 and the base portion 21 of the skin mold 2, it is a flexible tube, and the skin mold 2 is attached to the movable platen 26 by supplying compressed air or the like to the inside. A pressurizing means 9 is provided which is configured to be raised.

  The clamp means 8 presses the base material mold 4 closed with respect to the skin mold 2, and at least a pair of base end portions thereof are attached to the movable plate 26 so as to be swingable.

  Next, a second embodiment of the method for molding an interior product of a vehicle according to the present invention will be described together with the operation of the molding apparatus configured as shown in FIGS. Note that the same or corresponding components as those in the first embodiment described above are denoted by the same reference numerals, description thereof is omitted, and only different components are described.

  When molding the interior of the vehicle, the piston rod of the hydraulic cylinder 70 constituting the mold posture changing means 7 is driven to extend, and the movable plate 26 is held in an inclined state with respect to the horizontal. Is held in a posture in which the seal line 20a of the molding portion 20 is substantially horizontal and the base portion 21 is inclined with respect to the horizontal. Also in this embodiment, the skin H is held substantially horizontally by the skin holding means 1. Accordingly, the skin mold 2 is held in a posture in which the seal line 20a is parallel to the skin H that is held substantially horizontally. At this time, the clamp means 8 are opened at their tips separated from each other.

  Next, in this embodiment, the skin holding means 1 is moved horizontally by the conveying means 6 to the heating position C where the heating means 5 is fixed, the skin H is heated to a predetermined temperature and softened, and then the skin holding is performed. The means 1 is moved horizontally to the suction position A. When the heating means 5 is movably provided, the heating means 5 is moved into the suction position A between the base material mold 4 and the skin mold 2 (see arrow T in FIG. 1), and the skin H is moved to a predetermined temperature. Then, the heating means 5 is retracted to a position C deviated from between the substrate mold 4 and the skin mold 2 (see arrow T in FIG. 1). Then, the skin holding means 1 is moved downward by the conveying means 6 (see arrow S in FIG. 1), the skin H is brought into contact with the seal line 20a of the skin mold 2, and the motor 30 of the suction means 3 is driven. The space 22 in the molding part 20 is decompressed by the vacuum pump 31, so that the skin H is adsorbed on the surface of the molding part 20 through the air holes 23.

  At this time, the movable platen 26 is inclined with respect to the horizontal by the mold posture changing means 7, and the skin line 2a and the skin H of the skin mold 2 are both substantially horizontal and parallel. The elongation amount of the skin H from the state in contact with the surface 20a until it is adsorbed on the surface of the molded part 20 is averaged, and as a result, the thickness of the skin H is made uniform.

  When the skin H is adsorbed to the molding part 20 of the skin mold 2, the base material mold 4 moves downward as indicated by a chain line R in FIG. The mold is closed. In this embodiment, thereafter, as shown in FIG. 4, the piston rod of the hydraulic cylinder 70 of the mold posture changing means 7 is driven to retract, and the movable platen 26 is made horizontal. Thereby, in this embodiment, the base material mold 4 is positioned above the skin mold 2 in which the skin H is adsorbed on the surface of the molding portion 20, and the base material K and the skin H are caused by the weight of the base material mold 4. Is pressed between the skin mold 2 and the substrate mold 4.

  Furthermore, in this embodiment, the tip of each clamping means 8 is swung close so as to be close to each other, and the movable plate 26 and the base portion 21 of the skin mold 2 are held in a state where the base mold 2 is held so as not to rise. By sending compressed air or the like into the inside of the pressurizing means 9 provided between them, the skin mold 2 is raised with respect to the movable plate 26 and clamped with respect to the base mold 4, In addition to the weight of the substrate mold 4, the substrate K and the skin H are pressurized.

  At this time, as described above, the elongation amount of the skin H when the skin H is adsorbed to the skin mold 2 is averaged, so that the thickness of the skin H is made uniform. Since the posture of the skin mold 2 with respect to the skin H is maintained in such a relationship as to average, the posture of the skin H is not changed, so that the time of the molding cycle can be shortened. Since the outer skin H can be molded and joined to the base K before the temperature of the skin H decreases, a high-quality vehicle interior product N can be easily molded. In this embodiment, the substrate K and the skin H can be easily and reliably pressurized by utilizing the weight of the substrate mold 4.

Next, a third embodiment of a vehicle interior molding apparatus according to the present invention will be described with reference to FIG.

In addition, a lifting / lowering means 15 comprising a hydraulic cylinder or the like provided on the end panel 12 is connected to the lifting / lowering board 14. Therefore, the mold opening and closing direction in this embodiment is configured such that the skin mold 2 moves in the vertical direction with respect to the base mold 4.

  The upper surface of the pressure plate 13 extends substantially horizontally, and the base portion 41 of the base material mold 4 is attached to this upper surface. Therefore, in this embodiment, the holding part 40 of the base mold 4 is inclined with respect to the horizontal, as in the conventional technique shown in FIG.

  The elevator 14 is composed of a pair, the vicinity of the end of each elevator 14 is inserted into the guide bar 11, and the shaft 27 provided at a predetermined position of the skin mold 2 is an intermediate portion between the elevators 14. Are supported by each. The molded part 20 of the skin mold 2 is inclined with respect to the base part 21. A servo motor or the like is connected to the skin mold 2 as the mold posture changing means 7, and it rotates between a posture in which the seal line 20 a of the molding portion 20 is substantially horizontal and a posture in which the base portion 21 is substantially horizontal.

Further, the pressure plate 13 to which the base material mold 4 is attached has the pressure means 9 retracted and is held at the lowered position.

  In this state, the skin holding means 1 is positioned at the set position B by the transport means 6, the skin H is set at the set position B, and then transported in the horizontal direction to the heating position C. H is heated to a predetermined temperature and softened. Subsequently, the skin holding means 1 holding the softened skin H is moved in the horizontal direction to the suction position A. Also in this embodiment, since the posture of the skin holding means 1 does not need to be rotated or raised as in the prior art (FIG. 7), the skin mold 2 is lowered so as to approach the skin holding means 1 by the lifting means 15. The skin H can be adsorbed to the skin mold 2 in a short time after the heating is completed simply by moving it. When the heating means 5 is movable between the suction position A and the retracted position (heating position C) (see arrow T in FIG. 1), the skin H is applied to the skin holding means 1 at the set position B.

The skin H is adsorbed on the surface of the molding part 20. At this time, the posture of the skin mold 2 is such that the seal line 20a of the molding part 20 and the skin H are substantially horizontal and parallel. Therefore, the amount of elongation of the skin H from the state in which the skin H is in contact with the seal line 20a until it is adsorbed to the surface of the molded part 20 is averaged, and as a result, the thickness of the skin H is made uniform. This is the same as in the above-described embodiment.

  Subsequently, the base portion 21 of the skin mold 2 is rotationally driven around the shaft 27 so as to extend in the horizontal direction, and then the lifting means 15 is further driven to extend to lower the lifting board 14 so that the skin mold 2 is the substrate mold. 4 is closed, the pressurizing means 9 is extended and driven to raise the pressure plate 13 to which the base material mold 4 is attached, and the mold is clamped.
