  By the way, in the shaping | molding apparatus of patent document 1, two fixed molds are prepared for base material shaping | molding and skin shaping | molding, and it is made to replace with the time of shaping | molding of a base material, and the shaping | molding of a skin. For this reason, the mold cost rises, and it takes time to replace the fixed mold for each molding cycle, resulting in a longer molding cycle and, consequently, an increased cost of the molded product.

  Therefore, it is conceivable to mold using one fixed mold without changing the fixed mold between the molding of the base material and the molding of the skin. However, in this case, the material constituting the base material and the material constituting the skin are supplied to a single cavity formed by one fixed mold and a movable mold. In a portion that extends in a direction different from the main body plate portion, such as a plate portion, the material constituting the base material tends to appear on the front side during molding, and there is a possibility that a molding defect may occur.

  The present invention has been made in view of such a point, and its object is to suppress the occurrence of molding defects by making it difficult for the material constituting the base material to appear on the front side of the molded product. .

  In order to achieve the above object, in the present invention, a material filling space for forming the main body plate portion is formed in the cavity by advancing the slide die provided in the forming die, while the projecting plate portion is formed by retreating. A material filling space was formed.

Connected and configured to control these devices 8-10, 13, 14, 27, 28 and flow control valves 20, 22.

  Specifically, when receiving a molding start signal, the control device 40 first forms the cavities C1 and C2 and starts the molding of the base material 101, so that each of the devices 8 to 10, 13, 14, 27 is started. , 28 and the resin flow control valves 20, 22 are sent control signals. That is, as shown in FIG. 5A, the control device 40 causes the mold driving device 8 to move the movable mold closer to the fixed mold 2 to clamp the fixed mold and the movable mold 3, and the first and second The first and second main body molds 11 and 12 are brought into the base material molding position by the main body drive devices 13 and 14. Further, as shown in FIG. 5B, the first and second slide molds 25 and 26 are advanced by the first and second slide mold drive devices 27 and 28. Thereafter, the resin supply device 9 is operated and the resin flow control valve 20 is opened.

  When the supply of the resin constituting the base material 101 is completed, the control device 40 controls the devices 8 to 10, 13, 14, 27, and 28 and the flow rate control valves 20 and 22 to start forming the skin 102. Send a signal. That is, after the resin flow rate control valve 20 is closed, the control device 40 moves the first and second main body molds 11 and 12 to the left by the main body drive apparatuses 13 and 14 and the first and second slides. The first and second slide molds 25 and 26 are moved backward by the mold driving devices 27 and 28, and then the elastomer supply device 10 is operated and the elastomer flow control valve 22 is opened. The moving speed of the movable mold 3, the main body molds 11 and 12, and the slide molds 25 and 26, the supply amount and the flow rate of the resin and elastomer can be controlled to arbitrary values by the control device 40.

  Next, the point which shape | molds the panel member 100 using the shaping | molding apparatus 1 comprised as mentioned above is demonstrated. For example, polypropylene is used as the resin constituting the substrate 101, and this is prepared in a molten state in the resin supply device 9. As the material constituting the skin, for example, a foamable elastomer (foamed material) disclosed in Patent Document 1 is used, and this is prepared in the elastomer supply device 10. The elastomer is preferably a saturated styrene-based elastomer, and the foaming agent mixed therein may be anything that can foam the elastomer, such as an inorganic compound such as sodium bicarbonate or an azo compound. Examples include degradable foaming agents such as organic compounds.

  When a molding start signal is sent to the control device 40, the control device 40 clamps the movable mold 3 and the fixed mold 2 by the mold driving device 8 as shown in FIGS. Cavities C1 and C2 are formed. Further, as shown in FIG. 5A, the first and second main body molds 11 and 12 are moved to the base material forming position by the first and second main body type driving devices 13 and 14. Further, as shown in FIG. 5B, the first and second slide molds 25 and 26 are advanced by the first and second slide side drive devices 27 and 28. Then, the 1st and 2nd slide type | molds 25 and 26 contact | abut to the fixed side molding surface 2a, 2a. At this time, since the contact portions 25a of the first and second slide dies 25, 26 are softer than the fixed-side molding surfaces 2a, 2a, it is possible to prevent the concavo-convex shape for forming the wrinkles on the fixed-side molding surfaces 2a, 2a from being crushed. It is possible to do. Furthermore, since the contact portions 25a of the first and second slide dies 25, 26 are formed so as to extend along the fixed-side molding surfaces 2a, 2a, the pressure received by the fixed-side molding surfaces 2a, 2a is reduced. This also makes it possible to prevent the concavo-convex shape of the fixed-side molding surfaces 2a and 2a from being crushed.

  When the first and second slide molds 25 and 26 are advanced, the first and second cavities C1 and C2 are partitioned by the first and second slide molds 25 and 26, respectively. 26, material filling spaces R for forming the main body plate portion are formed.

  Next, the control device 40 operates the resin supply device 9 to start the resin supply and opens the resin flow rate control valve 20. As a result, the resin flows from the resin gates 15 and 15 through the resin passage 19 into the material filling space R for forming the main body plate portion. As shown in FIG. 6A, the resin that has flowed into the material filling space R for forming the main body plate portion has the shape of the base material 101.

  Thereafter, as shown in FIG. 6B, the control device 40 causes the first and second slide molds 25 and 26 to move backward by the first and second slide drive apparatuses 27 and 28. Then, in the first and second cavities C <b> 1 and C <b> 2, a material filling space S for forming the protruding plate portion is formed so as to surround the base material 101.

  Thereafter, the control device 40 moves the first and second main body molds 11 and 12 together with the base material 101 to the left by the first and second main body drive devices 13 and 14 as shown in FIG. And a space filled with the elastomer is formed between the fixed-side molding surface 2a. This space communicates with the material filling space S for forming the protruding plate portion. The amount of movement of the first and second body molds 11 and 12 at this time is substantially the same as the thickness dimension of the solid layer 102a.

  In synchronization with the movement of the first and second main body molds 11 and 12, the control device 40 operates the elastomer supply device 10 to start supplying the elastomer and opens the elastomer flow control valve 22. Thereby, the elastomer flows into the runner 18 through the elastomer passage 21. The resin flowing into the runner 18 flows into the first gate 16 side and the second gate 17 side through the runner 18 and flows into the material filling space S for forming the protruding plate portion of the first cavity C1 from the first gate 16. Then, it flows from the second gate 17 into the material filling space S for forming the protruding plate portion of the second cavity C2. The elastomer that has flowed into the material filling space S for forming the protruding plate portion flows so as to surround the base material 101 and also flows to the front side of the base material 101. As shown in FIG. 7A, the elastomer contacts the peripheral surface portion 2c of the fixed-side molding surface 2a and is molded by the peripheral surface portion 2c to become a solid layer 102a. Further, the elastomer that has spread over the entire front side of the substrate 101 contacts the vertical surface portion 2b of the fixed-side molding surface 2a and is molded by the vertical surface portion 2b. At this time, a texture pattern is formed on the entire surface of the skin 102 by the fixed-side molding surface 2a.

  Thereafter, as shown in FIG. 7B, the control device 40 moves the first and second main body molds 11 and 12 to the left by the first and second main body drive apparatuses 13 and 14. Thereby, the elastomer which has not yet solidified inside the skin 102 is stably foamed to form the foamed layer 102b. In this way, the panel member 100 in which the skin 102 is laminated on the base material 101 and the protruding plate portion 100b is formed of only an elastomer is obtained. When the panel member 100 is removed from the mold, the mold drive unit 8 moves the movable mold 3 to the left side to open the mold. When the mold is opened, the protruding plate portion 100b is made of only an elastomer and is elastically deformed. Therefore, the protruding plate portion 100b can be easily forcibly removed from the concavo-convex shape portion of the peripheral surface portion 2c of the fixed molding surface 2a.

  As described above, according to this embodiment, the panel member 100 in which the skin 102 is laminated on the base material 101 can be molded without replacing the fixed mold 2 and the movable mold 3 with other molds. Furthermore, after the first and second slide molds 25 and 26 are advanced to form the material filling space R for forming the main body plate portion in the first and second cavities C1 and C2, and the material of the base material 101 is supplied, Since the slide molds 25 and 26 are moved backward to form the material filling space S for forming the protruding plate portion and the material of the skin 102 is supplied, the material of the base material 101 appears on the front side of the panel member 100. Can be avoided, and the occurrence of molding defects can be suppressed.

  Further, since the contact portions 25a of the first and second slide molds 25 and 26 are made softer than the fixed-side molding surfaces 2a and 2a, the fixed-side molding is performed when the first and second slide molds 25 and 26 are advanced. Damage to the surfaces 2a and 2a can be suppressed. Further, the contact portions 25a of the first and second slide dies 25, 26 are formed so as to extend along the fixed-side molding surfaces 2a, 2a, thereby further suppressing damage to the fixed-side molding surfaces 2a, 2a. be able to. Thereby, the appearance deterioration of the panel member 100 by having provided the 1st and 2nd slide type | molds 25 and 26 can be suppressed.

  In addition, the material which comprises the base material 101 and the material which comprises the skin 102 are not restricted to an above-described material.

  In addition, the supply timing of the resin constituting the substrate 101 may be before mold closing or before mold clamping. In addition, the supply timing of the material constituting the skin 102 may be during the movement of the main body molds 11 and 12 or after the movement of the main body molds 11 and 12 is stopped.
