Description

  The present invention relates to a molding apparatus for resin vehicle interior parts and a method for manufacturing the same, and in particular, a terminal portion of a decorative cover member that is a soft material such as a leather, a main skin, and a fabric is embedded in a base material. The present invention relates to a molding apparatus that manufactures resin vehicle interior parts by molding and a manufacturing method thereof.

  2. Description of the Related Art Conventionally, there is known a technique for integrally molding a decorative surface covering member made of another member on a part of a resin vehicle interior part. As an example of the interior part for a vehicle using the decorative cover member, there is known a lining part such as a door lining or a side lining, or a part using a decorative decorative member partially formed on a molded resin.

  Such resin vehicle interior parts maintain the appearance at the boundary between the resin surface part and the decorative surface member by embedding the end portion of the decorative surface member in the molded resin, and improve the merchantability. Can be improved.

  As a technique for integrally molding a decorative cover member into a molded resin, one shown in FIGS. 11 to 13 is known (see, for example, Patent Document 1). According to this technique, after the decorative display member 120 is set in a molding die in advance, a molten resin is injected into the molding die, so that the decorative display member 120 and the molding resin are integrally molded. A product is formed. The molding die includes a movable die 101 and a fixed die 102, and a thin slide block 104 is provided on the fixed die 102 so as to advance and retreat, and a groove 102 a is formed adjacent to the slide block 104. Has been.

  In order to manufacture a resin vehicle interior part, first, as shown in FIG. 11A, a decorative cover member 120 formed into a predetermined shape made of a main skin, synthetic leather, fabric, or the like is used as a skin setting jig. To set the fixed mold 102 side. At this time, the terminal portion 121 of the decorative cover member 120 is inserted into the groove 102a. The terminal part 121 is a part embedded in the resin base material.

  Next, in a state where the terminal portion 121 is inserted in the groove 102a, the movable mold 101 provided with the edge 105 protruding from the surface of the mold is moved until a predetermined cavity is formed with the fixed mold 102 (FIG. 11 ( b)). At this time, the terminal unit 121 is located between the edge 105 and the slide block 104. Then, from this state, the slide block 104 is slightly slid toward the movable mold 101, and the terminal portion 121 is sandwiched between the tip portion of the slide block 104 and the edge 105 (FIG. 11C).

The fixed mold 102 and the cavity K ₁ formed between the movable mold 101 is injected the resin J from the gate (not shown) forming the surface material (FIG. 12 (a)). Then the slide block is retracted (back surface side of the decorative mounting member 120) movable mold 101 and after forming the cavity K ₂ between the fixed mold 102 and the slide block 104 (FIG. 12 (b)), not shown the gate of the resin J is injected into the cavity K ₂ from (FIG. 13 (a)), then interior parts for plastic vehicle is formed by the release (Fig. 13 (b)).

  As described above, the technique shown in FIGS. 11 to 13 can satisfactorily form the appearance of the boundary portion between the decorative cover member 120 and the surface material (general surface) of the resin vehicle interior part. That is, the decorative cover member 120 and the surface material can be continuously formed without forming a groove at the boundary.

  However, in the above technique, when the decorative display member 120 is set on the fixed mold 102, the terminal portion 121 is not inserted into the grooves 102a and 104a in a predetermined manner depending on the thickness and rigidity (rigidity) of the decorative display member 120. There was a fear. For example, as shown in FIG. 14, the terminal portion 121 may be doubled and inserted into the groove 104a. If it shape | molds in such a state, the external appearance in the boundary part of a molded product will become defect.

  In order to prevent such problems, when decorative materials made of several kinds of materials are used, the thickness and rigidity of these members are set to be constant, and a graining mechanism is added to the skin setting jig to It is conceivable that the grain is put into the groove by the graining mechanism.

  In addition, in order to prevent such a problem, conventionally, a molding device is known that includes a clamp device for pulling an end portion of a decorative cover member into a groove (see, for example, Patent Document 2). According to this technique, the clamp device has a pressing portion that can move forward and backward with respect to the movable mold, and the pressing portion includes an engaging step portion that protrudes inward.

  In a state where the presser part is completely retracted to the fixed mold side, the engaging step part enters the step part formed in the fixed mold, and the lower surface of the engaging step part is in contact with the bottom part of the fixed type step part. It will be in contact. At this time, a gap (groove) having a rectangular cross section is formed between the presser portion and the stepped portion so that the terminal portion of the decorative cover member can enter.

  According to such a clamp device, when the presser part is retracted, the terminal part of the decorative cover member placed on the fixed mold and the presser part come into contact with each other, and the terminal part of the decorative cover member is pressed by the presser part. Pulled to the fixed mold side. Then, when the presser part is completely retracted, the terminal part of the decorative cover member is sandwiched between the presser part and the step part in the gap (groove), and the decorative cover member is in close contact with the fixed mold.

JP 2003-154542 A (page 4-6, FIG. 1-16) Japanese Patent Laid-Open No. 2002-355860 (second page, FIGS. 9-14)

  However, in the method of graining the terminal portion into the groove by the graining mechanism, there may be a case where the graining mechanism is not added to the normal takeout robot. In addition, when several kinds of decorative display members are used, the thickness and rigidity of these materials are set to be constant, and the dimensional error of the material is controlled to be manufactured with high accuracy within about 0.5 mm. There must be.

  In the method of pulling the terminal part into the groove with the clamping device, there is a disadvantage that the terminal part is bent in the groove if it is too long, or if the terminal part is too short, the terminal part cannot be pulled into the groove. It must be managed accurately. In addition, since the cross section of the groove is rectangular, the decorative cover member is pressed at the same pressure at all locations of the groove when the terminal part is pulled in, so the terminal part may come out of the groove depending on the thickness and rigidity of the decorative cover member. As a result, there is a problem that the terminal portion is lifted from the groove.

  In view of the above problems, an object of the present invention is to form a resinous vehicle interior part molding apparatus that embeds a terminal portion of a decorative display member in a resin base material and integrally forms the decorative display member. By securely inserting the terminal portion into the groove portion of the molding device when set at a fixed position, it is possible to maintain a good appearance at the boundary portion of the resin vehicle interior part molded integrally with the decorative cover member. An object of the present invention is to provide an apparatus for molding resin vehicle interior parts and a method for manufacturing the same.

  According to the present invention, according to the present invention, a decorative cover member is disposed in a cavity formed by clamping a first mold and a second mold, and a resin is injected. The injected resin and the decoration A resin vehicle interior part molding apparatus for integrally molding a cover member, wherein the second mold includes a guide block capable of moving back and forth from the second mold toward the first mold, and the guide The problem is solved by forming a groove between the block and the groove so as to be narrower toward the bottom.

  As described above, the molding apparatus for resin vehicle interior parts according to the present invention is embedded in the interior of the resin vehicle interior parts in the second mold having the mold surface that forms the back side of the resin vehicle interior parts. A groove for inserting a terminal portion of the decorated display member to be inserted in advance before resin injection is formed. This groove is formed so as to be narrower toward the bottom. The second mold is provided with a guide block which can move forward and backward with respect to the first mold and forms one side surface of the groove when the mold surface is formed. Further, the other side surface that forms the groove facing the side surface of the guide block is formed as an inclined surface by notching the end portion of the second mold obliquely.

  Since it is configured in this manner, after the decorative cover member is molded to a predetermined size, the decorative cover member is moved in a state where the guide block has moved a predetermined distance in the direction of the first mold (decorative cover member set position). Place the terminal part in a fixed position of the second type so that the terminal part protrudes over a predetermined length beyond the groove, and then retract the guide block, the terminal part contacts the guide block and guides into the groove It will be done. When the guide block is completely retracted to the normal position, the terminal portion is housed in the groove.

  Thus, it can be set as the state which inserted the terminal part of the decorating member in the groove | channel formed in the 2nd type | mold reliably by the induction | guidance | derivation block. That is, since the shape of the groove is expanded toward the upper side, even a thick decorative cover member can be easily positioned in the groove. And since it is formed so narrow as the bottom part of a groove | channel, the pressure which presses a decoration surface display member becomes so large that it is drawn in to a bottom, and it can hold down firmly. At this time, even if the length of the terminal portion varies, once the terminal portion is drawn into the groove, it is surely guided toward the bottom by friction with the side surface of the groove.

  Therefore, it is possible to prevent a problem that the terminal portion is doubled in the groove or floats without completely entering as in the conventional case. The appearance at the boundary can be made favorable. Further, it is possible to reduce the incidence of defective products of resin vehicle interior parts manufactured in accordance with this, and to suppress variations in product quality.

  The second mold may include a slide mold capable of moving back and forth from the second mold toward the first mold in the cavity, and the groove may be formed by the slide mold and the guide block. It is. In this way, the cavity formed between the first mold and the second mold by pressing the slide mold against the first mold and holding the decorative cover member between the slide mold and the first mold. Can be reliably divided into a decorative surface side and a resin surface side. Therefore, it becomes possible to prevent the resin from wrapping around the surface of the decorative cover member.

  In this way, in the process of injecting the resin into the cavity, in the divided state, the resin is first injected on the side that becomes the surface of the molded product to form a surface material, and then the back surface of the molded product with the slide mold retracted By injecting the resin to the side to become, the back material of the decorative cover member can be formed. At this time, since the back surface material is connected to the surface material and the back surface of the terminal portion, the manufactured resin molded product can ensure the base material rigidity as a whole.

  Further, it is preferable that the guide block is provided with a notch step on a side surface forming one side surface of the groove. If the notch step is provided on the side of the guide block, the stepped part and the terminal part come into contact with each other when the decorative cover member is set at the fixed position of the second mold and the guide block is moved backward. The terminal portion can be reliably guided into the groove.

  In addition, it is preferable that the guide block is configured to advance and retract in a direction that forms a predetermined angle with respect to a direction from the first mold toward the second mold. If comprised in this way, when setting a decoration display member in the fixed position of a 2nd type, while ensuring that a guidance block does not become a hindrance and the terminal part protrudes beyond a step part, it secures. Can be made easier.

  Further, according to the present invention, there is provided a first mold having a mold surface that forms a design surface of a resin vehicle interior part, and a rear surface of the resin molded product that is disposed to face the first mold. A decorative surface member is placed in a cavity formed by a second mold having a mold surface to be injected and resin is injected into the cavity, and the decorative surface member is attached to the surface and the terminal of the decorative surface member A method of manufacturing a resin vehicle interior part having an embedded part therein, a step of moving a guide block provided in the second mold from the second mold toward the first mold, A step of disposing a decorative cover member molded to a predetermined size on the mold surface; and a step of retracting the guide block toward the second mold to contact a terminal portion of the decorative cover member; and the guide block By retracting it to the second mold A step of guiding the end portion in a groove formed between the mold and the guide block and having a width that is narrower toward the bottom; a step of clamping the first mold and the second mold to form a cavity; and A step of injecting a resin into the cavity and integrally molding the resin and the decorative surface covering member; and a step of releasing the first mold and the second mold and taking out the resin vehicle interior parts. Is solved.

  If it does in this way, it can set to the state where the terminal part of the decoration display member was inserted certainly in the slot formed in the 2nd type. Thereby, the external appearance in the boundary part of the resin surface of the manufactured resin vehicle interior components and a decorating surface can be kept favorable.

  According to the present invention, in a molding apparatus for resin vehicle interior parts for embedding and integrally molding a terminal portion of a decorative display member in a resin base material, and a manufacturing method thereof, the decorative display member is set at a fixed position. In this case, the terminal portion can be surely inserted into the groove portion of the molding apparatus, and the appearance of the terminal portion of the resin vehicle interior part molded integrally with the decorative cover member can be kept good.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The members and arrangements described below do not limit the present invention and can be variously modified within the scope of the gist of the present invention. 1 to 7 show an embodiment of the present invention, FIG. 1 is a perspective view showing an example of an interior part for a vehicle, FIG. 2 is a cross-sectional explanatory view of a resin molding apparatus according to the present invention, and FIG. FIG. 4 to FIG. 6 are explanatory views showing a manufacturing process of a vehicle interior part, and FIG. 7 is a partial cross-sectional view of the vehicle interior part. FIG. 8 is a partially enlarged explanatory view of a molding apparatus according to another embodiment. 9 and 10 are explanatory views showing a manufacturing process using a molding apparatus according to another embodiment.

  The resin molded product formed by the molding apparatus A according to the present invention is a resin vehicle interior having a decorative cover member 20 which is a soft material such as a genuine leather, urethane-coated leather, fabric, and film. A part S, for example, a door lining of an automobile as shown in FIG. The vehicle interior component S includes a decorative surface 22 that is exposed in a state where the decorative cover member 20 is adhered to the surface, and a surface material 10 that exposes a resin surface that is a base material. And the surface material 10 are separated by a boundary portion 23.

  As shown in FIG. 2, the molding apparatus A includes a first mold B that forms a mold surface on the product design surface side and a second mold C that forms a mold surface on the product back surface side. The first mold B includes the movable mold 1, and the second mold C includes the fixed molds 2 a and 2 b, the slide mold 4 that is disposed between the fixed molds 2 a and 2 b and moves forward and backward with respect to the movable mold 1 and the guide block 6. And is configured.

  The molding apparatus A may be configured to open the mold in either the vertical direction or the horizontal direction. Further, the movable mold 1, the slide mold 4 and the guide block 6 are configured to be movable by a driving device (not shown). As the drive mechanism, known means such as a hydraulic device, a pneumatic device, and a spring type can be used.

  The movable mold 1 is provided with a desired mold shape adapted to the vehicle interior part S, and an edge 3 protruding from the mold surface is provided as shown in FIG. The edge 3 is formed by processing the mold surface into an R shape. The edge 3 is formed along the boundary portion 23 between the decorative surface 22 of the decorative cover member 20 and the terminal portion 21 embedded in the resin base material (see FIG. 5).

  The fixed molds 2a and 2b are formed in accordance with the mold shape of the movable mold 1, and a molten resin passage 3a and a gate 3b are formed therethrough. And it is comprised so that molten resin (for example, polypropylene) may be supplied to a cavity via this channel | path 3a and the gate 3b.

  The slide mold 4 having a substantially rectangular cross section is disposed adjacent to the fixed mold 2b between the fixed molds 2a and 2b, and can be moved back and forth with respect to the movable mold 1 while being in sliding contact with the fixed mold 2b by a driving device (not shown). It is configured. As shown in FIGS. 2 and 3, the outer end of the slide die 4 is provided with a notch having a shape in which the end of the slide die 4 is obliquely cut out. A groove 5 having a predetermined depth is formed between 6 b and the slide mold 4. The terminal portion 21 of the decorative cover member 20 is inserted into the groove 5 as will be described later.

  When the first mold B and the second mold C are clamped, the edge 3 of the movable mold 1 and the shoulder 5a of the groove 5 are pressure-bonded with the decorative cover member 20 interposed therebetween, and the edge 3 and the shoulder The crimping | compression-bonding location of the part 5a turns into the boundary part 23 of the decorating surface 22 and the terminal part 21 of the decorating member 20 (refer FIG.5 (b)).

  The guide block 6 having a predetermined height is disposed between the fixed mold 2a and the slide mold 4, and is fixed to the tip of a rod 7 connected to a drive device (not shown). The inner peripheral surface 2c of the fixed mold 2a of this example is an inclined surface so that the distance from the facing slide mold 4 decreases as the position becomes farther from the movable mold 1. The guide block 6 of this example has a substantially trapezoidal cross section according to the inclined surface, and the outer surface 6a is inclined. Further, the drive device is configured to move the guide block 6 in a direction along the inclined surface via the rod 7.

  With this configuration, when the rod 7 moves the guide block 6 from the state shown in FIG. 2 in the direction toward the movable mold 1 by a drive device (not shown), the guide block 6 moves in the direction of the movable mold 1 as shown in FIG. And move outward (upward in the figure).

  Further, a step 6c is formed at the lower end of the inner side surface 6b of the guide block 6 (the end opposite to the movable mold 1) by cutting out the inner side surface 6b. As will be described later, when the guide block 6 moves backward, the step portion 6c comes into contact with the terminal portion 21 of the decorative cover member 20 arranged at a fixed position on the fixed mold 2b so that the terminal portion 21 enters the groove 5. Induce.

  Next, a method for manufacturing the vehicle interior part S using the molding apparatus A will be described with reference to FIGS. FIG. 4A shows a state in which the guide block 6 is in the decorative cover member setting position. At this time, the lower side surface 6d of the guide block 6 is located closer to the movable die 1 than the side surface 4a forming the cavity of the slide die 4.

  That is, at the decorative cover member setting position, when the decorative cover member 20 is placed at a fixed position, the guide block 6 does not get in the way, and the terminal portion 21 of the decorative cover member 20 is directed from the groove 5 to the fixed mold 2a. Space that can be placed in the protruding state is secured.

  In this state, as shown in FIG. 4A, the decorative cover member 20 molded to a predetermined size is set at a fixed position on the fixed mold 2b by the skin setting jig. In the state set at this fixed position, the terminal portion 21 protrudes beyond the groove 5 of the slide mold 4 to the fixed mold 2a side by a length within a predetermined range. The protruding length is, for example, about 10 mm to 15 mm and is set to be shorter than the depth of the groove 5. However, as long as it is within a predetermined range, the dimension need not be set with high accuracy as in the conventional case. If it is desired to increase the protruding length, the setting may be changed to increase the depth of the groove 5. Further, the groove 5 is formed so as to be narrower toward the bottom, but the narrower toward the bottom includes a case where the groove width is constant in the middle of the depth direction of the groove 5 or in the vicinity of the bottom.

  After the decorative cover member 20 is set at a fixed position, the guide block 6 is driven by the drive device, and between the fixed mold 2a and the slide mold 4 along the inclination direction of the inner peripheral surface 2c of the fixed mold 2a. It will be drawn. FIG. 4B shows a state where the guide block 6 is at the chuck position. The chuck position is a position where the step portion 6c and the tip end portion of the terminal portion 21 come into contact with each other while the guide block 6 is moving backward.

  When the guide block 6 is further retracted from the chuck position, the terminal portion 21 is guided into the groove 5 as shown in FIG. Even when the protruding length is longer than the length shown in FIG. 4B, the terminal portion 21 contacts the lower side surface 6d and the inner side surface 6b and is guided into the groove 5.

  FIG. 5A shows a state in which the guide block 6 is completely retracted to the retracted position between the fixed mold 2a and the slide mold 4, and the groove 5 is formed. In this state, the terminal portion 21 is guided into the groove 5 and finally maintained in a state of being inserted into the groove 5.

  Thus, the terminal part 21 can be guided into the groove 5 by setting the decorative cover member 20 molded to a predetermined size at a fixed position and retracting the guide block 6. The groove 5 expands toward the top, making it easy to draw the tip of the terminal portion 21 into the groove 5. As a result, the terminal portion 21 is not sufficiently inserted into the groove 5 as in the prior art, and the terminal portion 21 is doubled in the groove 5 or floats out of the groove 5. Can be prevented.

  Moreover, since the shape of the groove 5 is not a rectangular cross section as in the prior art, and the inner side surface is inclined so that the bottom of the groove 5 becomes narrower, the length of the terminal portion 21 may vary. Even if the thickness and rigidity of the decorative cover member 20 are different, the terminal portion 21 can be reliably pulled into the groove 5.

  That is, since the groove 4 is set to be narrower toward the bottom and narrower than the thickness of the decorative cover member 20, the terminal block 21 once drawn into the groove 5 has the guide block 6 on the fixed mold 2 a side. As it retreats, a frictional force is gradually applied to the inner surface of the groove 5 and is sandwiched by the inner surface of the groove 5 to receive pressure and be guided to the bottom side. Thereby, there is no possibility that the terminal part 21 may come out of the groove 5 and float up.

  In order to guide the terminal portion 21, it is desirable that the guide block 6 has a stepped portion 6 c. However, the step portion 6c does not necessarily have to be formed, and when the step portion 6c is not formed, the terminal portion 21 is drawn into the groove 5 while abutting against the inner side surface 6b.

  When the terminal portion 21 is guided into the groove 5, as shown in FIG. 5 (b), the movable mold 1 is moved to a predetermined position by a driving device in the direction of the fixed molds 2a and 2b, and the mold is clamped. A cavity is formed between 1 and the stationary molds 2a and 2b. At this time, the boundary portion 23 of the decorative cover member 20 is formed between the edge 3 and the shoulder portion 5a.

Then, as shown in FIG. 5C, the slide mold 4 is moved to the movable mold 1 side, and the decorative cover member 20 is sandwiched between the movable mold 1 and the slide mold 4. The edge 3 is pressed against the boundary portion 23 between the decorative surface 22 of the decorative cover member 20 and the terminal portion 21. At this time, a first cavity K ₁ is formed between the movable mold 1, the fixed mold 2 a, the guide block 6 and the slide mold 4.

  In this manner, the boundary portion 23 of the decorative display member 20 is pressed against and held by the edge 3, so that in the resin injection step described below, the injected resin is the decorative surface of the decorative display member 20. It becomes possible to prevent entering between 22 and the movable mold | type 1 and between the back surface of the decorating member 20 and the slide mold | type 4. FIG.

Then, after interposing by holding the decorative facings member 20 and the slide die 4 and the movable mold 1, as shown in FIG. 6 (a), injecting the molten resin J into the first cavity K _1. That is, the gate 3b of the fixed mold 2a, a predetermined amount of the molten resin J required to mold the surface member 10 of the vehicle interior part S is injected, the resin is injected in a molten state into the first cavity K ₁ The

  Thereafter, the decorative display member 20 and the molten resin J are integrally molded by press-clamping. While maintaining the state of this mold clamping, cooling which hardens the molten resin J is performed, the decorating member 20 and the resin are integrated, and the terminal portion 21 and the surface material 10 of the decorating member 20 are integrated. The molded product 30 being manufactured is formed (see FIG. 6B).

Next, as shown in FIG. 6B, the slide mold 4 is retracted to a predetermined position. At this time, the molded product 30 being manufactured is sandwiched and fixed between the movable mold 1 and the fixed mold 2a, and is located on the movable mold 1 side. By retracting the slide mold 4, a second cavity K ₂ is formed between the slide mold 4, the fixed mold 2 b, and the movable mold 1 (actually, the back surface of the molded product 30 being manufactured). Thus slide 4 is the back side of the second surface material 10 in the cavity K ₂ is partially exposed by retraction.

Then, as shown in FIG. 6 (c), injecting molten resin J into the second cavity K _2. That is, the gate 3b of the fixed mold 2b, emitted molten resin J having a predetermined amount necessary for forming the backsheet 40 of the vehicle interior part S is, resin is injected in a molten state to a second cavity K ₂ The

At this time, the resin injected into the second cavity K ₂ from the gate 3b reaches the rear portion of the terminal portion 21, associated with the surface material 10 exposed to the second cavity K ₂ on the back side of the terminal portion 21 To do.

Thereafter, by applying clamping pressure, the molded article 30 in the process of production, integrally molded and supplied molten resin J into the second cavity K _2. While maintaining the state of this mold clamping, cooling which hardens the molten resin J is performed, and the back surface material 40 is formed in the back side of the decorating member 20 (refer FIG. 7). In this way, the vehicle interior part S in which the molded product 30 and the back surface material 40 being manufactured are integrally formed is formed.

  After completion of molding, the mold is opened and the completed vehicle interior part S is taken out. FIG. 7 shows a cross-sectional view of the vehicle interior component S manufactured. In the vehicle interior component S, the back surface material 40 and the surface material 10 are connected to each other on the back side of the terminal portion 21, and the necessary base material rigidity can be ensured as a whole.

  As described above, according to the molding apparatus A of this example, the terminal portion 21 of the decorative cover member 20 is placed into the groove 5 adjacent to the fixed mold 2a and the slide mold 4 on which the decorative cover member 20 is set. Since the guiding block 6 to be guided is formed, the terminal block 21 of the decorative cover member 20 can be reliably guided into the groove 5 by the guiding block 6.

  As a result, it is possible to prevent the occurrence of a problem that the tip of the terminal portion 21 is visible at the boundary portion 23 of the vehicle interior part S to be finally molded or the terminal portion 21 is molded into a rounded state. It is possible to keep the appearance of the resin molded product favorable.

  Further, according to the molding apparatus A of the present example, since the terminal portion 21 can be reliably guided, the occurrence rate of molding defects can be reduced and the product rigidity of the molded resin molded product can be reduced. The variation is less likely to occur and the substrate rigidity is stabilized. Moreover, since it is the structure which guide | induces the terminal part 21 in the groove | channel 5, it is not necessary to manage the shaping | molding dimension of the decorating display member 20 with high precision.

  Furthermore, it is possible to guide the terminal portion 21 into the groove 5 without matching the physical properties such as the thickness and rigidity of the decorative display member 20 that is an insert. Since it is not necessary to match the physical properties of the decorative cover member 20, the manufacturing cost of the vehicle interior part S can be reduced.

  Further, since it is not necessary to add a special mechanism such as a graining mechanism to the skin setting jig for setting the decorative cover member 20 on the fixed mold 2a, the skin setting jig and the robot can be a simple mechanism. In addition, it can be shared.

  In the above embodiment, the slide mold 4 is described as a mold disposed between the fixed molds 2a and 2b. However, the present invention is not limited to this, and the slide mold 4 and the fixed mold 2b are integrally formed. It may be a mold.

  Further, when the guide block 6 is retracted and the terminal portion 21 of the decorative cover member 20 is guided into the groove 5, the stepped portion 6 c is caught by the terminal portion 21, so that the decorative cover member 20 is evenly moved to the groove 5. There is a possibility of causing a position shift without being pulled. In order to prevent such a problem, as shown in FIG. 8, when the guide block 6 is retracted, the decorative display member 20 may be pressed against the fixed mold 2 b by the pressing jig 8 to prevent movement. .

  In the above embodiment, the terminal block 21 is guided into the groove 5 by retracting the guide block 6 in the oblique direction along the inner peripheral surface 2c of the fixed mold 2a. 9 and FIG. 10, the terminal portion 21 may be retracted into the groove 5 by retracting in a direction substantially perpendicular to the movable mold 1.

  When configured in this way, as shown in FIG. 9 (a), after setting the decorative cover member 20 at a fixed position on the fixed mold 2b, the guide block 6 is retracted in the vertical direction.
