  The present invention relates to a manufacturing apparatus and a manufacturing method for manufacturing a metal resin composite member including a metal member and a resin member attached to the metal member.

  FIG. 8 is a perspective view showing a metal-resin composite member W configured by attaching an injection-molded synthetic resin resin member 20 to the back surface 10A of the aluminum panel 10 formed in a required shape. This metal resin composite member W is used as a decorative panel member attached to a vehicle interior member such as an instrument panel or a floor console in a state where the aluminum panel 10 is exposed to the outside. As shown in FIGS. 8 to 10, the resin member 20 is molded in a state where it contacts the back surface 10 </ b> A on the back side of the aluminum panel 10. The resin member 20 shown in FIG. 8 includes a plurality of first mounting pieces 22 erected on the back side of the aluminum panel 10 for mounting to a counterpart member (vehicle interior member) and a plurality of sides extending to the side of the panel 10. The second mounting piece 24, the first edge portion 26 along the inner edge of the circular first opening portion 12, and the second edge portion 28 along the inner edge of the rectangular second opening portion 14 include a plurality of connecting portions 29. It is a single member arranged continuously. The back surface 10A of the aluminum panel 10 has a number of fine irregularities (not shown) formed by a known etching process, which is one of the surface treatment techniques, and the resin member 20 is attached to the panel 10 by an anchor effect. It is worn. Reference numeral 29A denotes an excess resin portion formed from a resin solidified in the injection runner 38 of the manufacturing apparatus M1 when the resin member 20 is molded by the manufacturing apparatus M1 described later. This excess resin portion 29A is described above. It is formed in a state standing on the continuous portion 29.

  The metal resin composite member W described above is manufactured using a manufacturing apparatus M1 schematically shown in FIG. The manufacturing apparatus M1 is a so-called injection mold, and a cavity 34 is formed between the first mold 30 capable of holding the aluminum panel 10 and the back surface 10A of the aluminum panel 10 by closing the mold with the first mold 30. And a second mold 32 to be defined. As shown in FIG. 12, the second molding die 32 is configured to mold the first mounting piece 22, the second mounting piece 24, the first edge portion 26, and the second edge portion 28 of the resin member 20 described above. The four recesses 34A, 34B, 34C, 34D and the communication portions 34E for forming the connection portions 29 are recessed, and the first to fourth recesses 34A, 34B, 34C, 34D and the communication portions are communicated. The portion 34E opens toward the first mold 30 to form the cavity 34. That is, the recessed portions 34A, 34B, 34C, 34D of the cavity 34 are connected via the respective communication portions 34E. The second mold 32 is provided with an injection port 36 and a plurality of injection runners 38 that spatially communicate the communication port 34 </ b> E with the injection port 36 and the cavity 34.

Therefore, the molten resin P is injected from the resin injection nozzle N in contact with the injection port 36 with the first molding die 30 and the second molding die 32 holding the aluminum panel 10 closed. The resin P is injected into each communicating portion 34E of the cavity 34 through each injection runner 38. The resin P moves from the communication portions 34E into the first to fourth recesses 34A, 34B, 34C, 34D, and gradually solidifies in a state where the resin P is in contact with the back surface 10A of the aluminum panel 10. The first mounting piece 22, the second mounting piece 24, the first edge portion 26, the second edge portion 28, and the continuous portion 29 of the resin member 20 molded in the cavity 34 by the solidification of the resin P are caused by an anchor effect.

  By the way, the molten resin P injected from the injection port 36 comes into contact with the second mold 32 when moving the injection runners 38, and the communication portions 34 </ b> E of the cavity 34 and the first to fourth elements. When the recesses 34A, 34B, 34C, 34D are moved, both the second mold 32 and the aluminum panel 10 are contacted. For this reason, the temperature of the resin P gradually decreases after the injection, and the viscosity gradually increases accordingly. Therefore, in the manufacturing apparatus M1 described above, a plurality of injection runners are provided as shown in FIGS. 11 and 12 in order to efficiently distribute the molten resin P to the entire depressions 34A, 34B, 34C, 34D of the cavity 34. 38 is provided. However, depending on the shape and size of the resin member 20 and the size of the manufacturing apparatus W1, it may be difficult to provide an appropriate number of injection runners 38 at appropriate positions. Therefore, at a portion of the cavity 34 far from the injection runner 38 (for example, each S portion in FIG. 12), the viscosity of the resin P has already increased considerably when the portion is reached. For this reason, the resin P is solidified without entering a large number of the irregularities formed on the back surface 10 </ b> A of the aluminum panel 10. Accordingly, an appropriate anchor effect cannot be obtained, and the molded resin member 20 is not firmly attached to the aluminum panel 10, and the first mounting piece 22, the second mounting piece 24, the first edge portion 26, the second edge The inconvenience that the edge portion 28 and the continuous portion 29 easily peel off has occurred.

  Next, a metal resin composite member manufacturing apparatus and manufacturing method according to the present invention will be described below with reference to the accompanying drawings by way of preferred examples. In addition, an Example demonstrates the manufacturing apparatus and manufacturing method which shape | mold the metal resin composite member W shown in FIG. 8 comprised from the aluminum panel 10 and the resin member 20. FIG.

  FIG. 1 is a side sectional view schematically showing a shape of a metal resin composite member manufacturing apparatus M according to an embodiment. The manufacturing apparatus M according to the embodiment includes a first mold 40 that can hold the aluminum panel 10 of the metal resin composite member W and a back surface (outer surface) 10A of the aluminum panel 10 by closing the mold with the first mold 40. And a second molding die 42 defining a cavity 44. The manufacturing apparatus M is a so-called injection mold, the second mold 42 is fixed to the second frame 43, and the first mold 40 is fixed to the first frame 41. Accordingly, in the manufacturing apparatus M, the first mold 41 is moved close to the second mold 42 by moving the first frame 41 toward the second frame 43, and the first frame 41 is moved from the second frame 43. The first molding die 40 is separated from the second molding die 42 and opened by moving to the separating side.

  As shown in FIG. 1, the first mold 40 is made of die steel made of molybdenum-tungsten or the like, and a set portion 46 on which the aluminum panel 10 is set is formed. In addition, a pipe 48 through which water or oil as a heat medium passes is embedded inside the first mold 40, and the resin P injected into the cavity 44 is heated or cooled by heating or cooling the aluminum panel 10. It can be kept warm or cooled.

  As shown in FIG. 2, the second mold 42 is made of die steel or the like made of molybdenum-tungsten, and the first mounting piece 22 (component) and the second mounting piece 24 (component) of the resin member 20. ), First to fourth recessed portions 44A, 44B, 44C, 44D for forming the first edge portion 26 (component) and the second edge portion 28 (component), and the connecting portions 29 are formed. A communicating portion 44E is recessed. That is, the first to fourth recessed portions 44A, 44B, 44C, 44D of the cavity 44 are connected via the communication portions 44E. Further, the second mold 42 is provided with an injection port 50 and a plurality of injection runners 52 that spatially communicate the communication port 44 </ b> E of the injection port 50 and the cavity 44.

  Furthermore, the second mold 42 includes a plate-shaped movable mold body 42A that can slide between the position shown in FIGS. 1 and 4 and the position shown in FIG. In the movable body 42A, openings corresponding to the respective injection runners 52 are formed. That is, when the movable mold body 42A is moved to the position of FIGS. 1 and 4, the openings formed in the movable mold body 42A are aligned with the respective injection runners 52, and the injection port 50, the cavity 44, and the like. Will be in communication. Further, when the movable mold 42A is moved to the position of FIG. 5, the openings formed in the movable mold 42A are retracted from the respective injection runners 52, so that the injection port 50 and the cavity 44 are not in communication. It is configured to be in a state. Furthermore, a pipe 54 through which water or oil as a heat medium passes is embedded in the second mold 42, and the resin P injected into the cavity 44 can be kept warm or cooled.

  Further, as shown in FIGS. 1 to 3, the second molding die 42 is a heat insulating material having lower thermal conductivity than the second molding die 42 at the opening edge of the cavity 44 that opens to the first molding die 40 side. A member 60 is provided. In other words, the heat insulating member 60 is provided along the opening edge portions of the first to fourth recessed portions 44A, 44B, 44C, and 44D and the opening edge portions of the communication portions 44E. This heat insulating member 60 does not constitute the entire wall surface facing the cavity 44 of the second mold 42, but a portion from the abutting surface portion that contacts the back surface 10 </ b> A of the aluminum panel 10 in the second mold 42 to the required depth. It is composed. As a result, the entire opening edge of the cavity 44 that opens to the first molding die 40 side in the second molding die 42 is maintained at a lower thermal conductivity than the second molding die 42.

  The heat insulating member 60 described above is formed of a foam metal such as a stainless steel foam. As is well known, this foam metal is a metal porous body having the same three-dimensional network structure as a resin foam such as sponge, and the heat insulating member 60 of the embodiment has a porosity of 70 to 95%. Has been. The foam metal is divided into an open cell structure and a closed pore structure from the structural aspect, but the heat insulating member 60 of the embodiment preferably employs a closed pore structure. That is, in the foam metal having a closed pore structure, even if the high-temperature molten resin P comes into contact with the heat insulating member 60, there is no inconvenience that the resin P enters the pores. The heat conductivity of the heat insulating member 60 is about 0.1 W / m · K formed from a stainless steel foam having a porosity of 95%, and the heat of the second mold 42 formed from die steel. Since the conductivity is about 48 W / m · K, it has sufficient heat insulation performance. Further, since the heat insulating member 60 made of foam metal is resistant to heat, it does not deteriorate or deform even when the molten high-temperature resin P comes into contact.

  Therefore, as shown in FIGS. 3 and 4, the portion of the molten resin P injected into the cavity 44 adjacent to the aluminum panel 10 is in contact with the heat insulating member 60 and not the second mold 42. That is, in the manufacturing apparatus M of the embodiment, since the heat of the portion adjacent to the aluminum panel 10 in the resin P is difficult to conduct to the second mold 42 by the heat insulating member 60, the temperature drop of the resin P is suppressed and the fluidity is deteriorated. It is designed to prevent it. As a result, the resin P injected into each communicating portion 44E of the cavity 44 is easy to flow while in contact with the back surface 10A of the aluminum panel 10, and the first to fourth recessed portions 44A, 44B, 44C. , 44D.

  Furthermore, the 2nd shaping | molding die 42 is provided with the some press die part 62 which moves so that it can advance / retreat toward the communicating part 44E of the cavity 44, as shown in FIGS. As shown in FIGS. 2 and 3, these pressing mold portions 62 are disposed on a wall portion facing the opening side in the communication portion 44 </ b> E of the cavity 44, and partially constitute a wall surface of the communication portion 44 </ b> E. . Each pressing die 62 is advanced to the first mold 40 side with respect to the communication portion 44E (FIG. 5) and retracted with respect to the communication portion 44E by appropriate biasing means (not shown) (FIG. 5). 1 and FIG. 4). Accordingly, when each pressing die 62 is moved forward, the resin P injected into the communication portion 44E is pressed, and the resin injected into the first to fourth recesses 44A, 44B, 44C, 44D. Pressure is also applied to P. As a result, the resin P is pressed against the back surface 10A of the aluminum panel 10 and enters the irregularities formed on the back surface 10A. In addition, the moving amount | distance of each press type | mold part 62 is 1 mm or less. Further, as the urging means for moving each pressing mold portion 62, one utilizing hydraulic pressure or mechanical one using a motor or the like is employed.

  Next, the manufacturing method of the metal resin composite member of the Example using the manufacturing apparatus M comprised as mentioned above is demonstrated.

  First, the separately formed aluminum panel 10 is set on the set portion 46 of the first mold 40, the first mold 40 is brought close to the second mold 42, and the manufacturing apparatus M is closed (see FIG. 1). Then, the aforementioned movable mold 42A was moved to the position shown in FIG. 1 and melted from the resin injection nozzle N in contact with the injection port 50 with the injection port 50 and the cavity 44 communicating spatially. Resin P is injected into the injection port 50. As a result, the resin P is injected into the cavity 44 through each injection runner 52.

  As shown in FIG. 4, the resin P that has moved to each communication portion 44 </ b> E contacts the back surface 10 </ b> A of the aluminum panel 10 and the heat insulating member 60, and enters the first to fourth recesses 44 </ b> A, 44 </ b> B, 44 </ b> C, 44 </ b> D. It moves in the communication part 44E toward. When the heated resin P moves through the communication portion 44E, the heat insulation member 60 has lower thermal conductivity than the second mold 42, so the heat of the resin P moves to the second mold 42. It is hard to do. Therefore, the temperature drop of the resin P is suppressed, and the fluidity of the resin P is hardly deteriorated (viscosity is reduced).

  The resin P in which the temperature drop is suppressed in the communication portion 44E is sequentially filled in the first to fourth recesses 44A, 44B, 44C, and 44D. The portions of the resin P injected into the first to fourth recesses 44A, 44B, 44C, 44D adjacent to the aluminum panel 10 have a heat conductivity lower than that of the second mold 42 in the heat insulating member 60. Therefore, the temperature drop is suppressed, the fluidity is hardly deteriorated (viscosity is lowered), and it enters into the unevenness formed on the back surface 10A.

  When the injection of the resin P into the cavity 44 is completed, as shown in FIG. 5, the movable mold body 42 </ b> A is moved to the position shown in FIG. 5 to block the spatial communication between the injection port 50 and the cavity 44. Under this condition, each pressing die 62 is moved forward to the first molding die 40 side, and the resin P injected into the cavity 44 is pressurized. As a result, the resin P is pressed against the back surface 10A of the aluminum panel 10 and is pressed into the unevenness formed on the back surface 10A.

  Then, the cooled heat medium is circulated through the pipe 48 of the first mold 40 and the pipe 54 of the second mold 42, and the solidification of the resin P in the cavity 44 is promoted while the second mold 42 is cooled. When the solidification of the resin P is completed, the pressurization by the pressing mold portion 62 is released, the first molding die 40 is separated from the second molding die 42, and the manufacturing apparatus M is opened, and the manufactured metal resin composite member By removing W from the second mold 42, the molding of the resin member 20 is completed.

  Therefore, according to the manufacturing method of the metal resin composite member W using the manufacturing apparatus M of the embodiment, the entire opening edge facing the aluminum panel 10 of the cavity 44 in the second mold 42 is provided at the opening edge. Since the heat insulation member 60 maintains a lower thermal conductivity than that of the second mold 42, the temperature drop of the portion of the resin P injected into the cavity 44 that contacts the back surface 10 </ b> A of the aluminum panel 10 is suppressed. Prevents deterioration of fluidity. That is, since the resin P injected into the cavity 44 is solidified in a state where it enters a large number of irregularities formed on the back surface 10A of the aluminum panel 10, the anchor effect is appropriately manifested. Thereby, each 1st attachment piece 22, each 2nd attachment piece 24, each 1st edge part 26, and 2nd edge part 28 which are the structural parts of the resin member 20 are firmly attached to the aluminum panel 10 by the anchor effect. It becomes difficult to peel off from the panel 10. And also in each connection part 29, it is firmly fixed to the aluminum panel 10 similarly to a component. In addition, since the resin P injected into the cavity 44 is pressurized by the pressing mold 62, the resin P is pushed into the irregularities formed on the back surface 10A of the aluminum panel 10, and the anchor effect is appropriately and reliably exhibited. Can be made.

In the opening edge part of the part 44E, you may make it provide only in the opening edge part of each communicating part 44E. Thereby, since the opening edge part of each communicating part 44E in the 2nd shaping | molding die 42 is maintained by the heat insulation member 60 in heat conductivity lower than the 2nd shaping | molding die 42, the temperature fall of resin P in this communicating part 44E is carried out. The resin P can be smoothly injected into each of the first to fourth recesses 44A, 44B, 44C, 44D, and the constituent parts of the resin member 20 can be appropriately applied to the back surface 10A of the aluminum panel 10.
