Hereinafter, an embodiment of a hot press machine and a method for molding a metal-resin composite will be described.
As shown in FIGS. 2 and 3, in the skeleton member 20, a layer of fiber reinforced resin material (fiber reinforced resin layer 23) is provided on a press-formed steel plate 21 with a layer of adhesive material (adhesion layer 22) interposed therebetween. It has an integrally formed structure. The skeleton member 20 is a metal resin composite in which a steel plate 21 is reinforced with a carbon fiber reinforced resin (CFRP). The steel plate 21 is made of a hot dip galvanized steel plate (SCGA) or a cold rolled steel plate (SPC). The fiber reinforced resin layer 23 is formed of a carbon fiber reinforced resin containing a discontinuous carbon fiber with a thermosetting resin material (epoxy resin material) as a base material. The adhesive layer 22 is made of a thermosetting resin material (epoxy resin material). As the resin material forming the adhesive layer 22, a resin material suitable for adhering the steel plate 21 and the carbon fiber reinforced resin is adopted. The skeleton member 20 is molded by hot pressing using a hot pressing device, specifically by SMC (sheet molding compound) molding method.

Hereinafter, the hot press device used for forming the skeleton member 20 will be described.
As shown in FIGS. 4 to 6, the hot pressing device 30 has a mold device 40 including a fixed mold 41 and a movable mold 43. A space SP1 (FIG. 5) in which the skeleton member 20 is molded is defined between the fixed mold 41 and the movable mold 43 in the mold device 40.

A concave portion 44 having a shape recessed downward is provided on an upper portion of the fixed die 41. At the time of forming the skeleton member 20, the steel plate 21, the adhesive sheet that will become the adhesive layer 22, and the SMC that will become the fiber reinforced resin layer 23 are set in the recesses 44. In addition, SMC is a sheet-shaped sheet made by impregnating a discontinuous carbon fiber with a resin paste prepared by mixing a thermosetting resin material, a curing agent, a thickener, an internal release agent, a filler, etc. It is the one. SMC is handled well by heating it under a predetermined temperature condition to increase its viscosity.

The movable die 43 is a mother die 45 arranged to be movable relative to the fixed die 41 in the up-down direction (die clamping direction [downward in FIG. 4] and die opening direction [upward in FIG. 4]), and the same die. And a nesting member 46 attached so as to be movable relative to the vertical direction. An annular wall 47 protruding in an annular shape is provided below the mother die 45. A seal member 48 extending over the entire circumference is attached to the inner peripheral surface of the annular wall 47. When performing the hot pressing by the hot pressing device 30, the die clamping of the die device 40 is performed by moving the mother die 45 in a direction approaching the fixed die 41 (downward in FIG. 4) by a hydraulic cylinder (not shown). To be executed.

As the mold device 40 is clamped, the inner peripheral surface of the seal member 48 comes into contact with the outer peripheral surface of the fixed mold 41 over the entire circumference. At this time, the seal member 48 closes the gap between the outer peripheral surface of the fixed die 41 and the inner peripheral surface of the movable die 43 (specifically, the annular wall 47 of the mother die 45), so that the fixed die inside the mold device 40. The inside and outside of the space defined by 41 and the movable die 43 are sealed.

The nest 46 has an annular shape extending along the end of the space SP1. The insert 46 is fitted into and retractable from an annular ring groove 50 formed on the lower surface of the mother die 45. Inside the annular groove 50, a plurality of springs 49 are provided at intervals. One end of each spring 49 is in contact with the upper surface of the nest 46, and the other end is in contact with the bottom surface of the annular groove 50. When the mold device 40 is in the mold open state (the state shown in FIG. 4), the insert 46 moves downward due to the urging force of the spring 49, and the tip portion of the insert 46 escapes from the inside of the annular groove 50. become. On the other hand, when the mold device 40 is in the mold clamped state (the state shown in FIG. 5), the nesting member 46 moves upward against the urging force of the spring 49 and is housed in the annular groove 50. Become.

The tip end surface of the insert 46 has a step portion 51 having a shape in which the outer peripheral side projects toward the fixed mold 41 side rather than the inner peripheral side. When the tip of the insert 46 comes into contact with the steel plate 21 during the mold clamping of the mold device 40, between the portion of the tip surface of the insert 46 on the inner peripheral side of the step 51 and the upper surface of the steel plate 21. A gap 52 (FIG. 6) is formed. In the mold device 40 of this embodiment, the end portion 22B of the adhesive sheet 22A is housed in the gap 52.

The heat press device 30 has a vacuuming device 60 for removing gas in the space defined by the fixed mold 41 and the movable mold 43 inside the mold device 40 prior to heat pressing the skeleton member 20. .. The evacuation device 60 has a negative pressure tank 61 in which a pressure lower than the atmospheric pressure is accumulated, and a negative pressure pump 62 connected to the negative pressure tank 61. A through hole 63 is formed in the annular wall 47 of the mother die 45 above the portion where the seal member 48 is disposed. The through hole 63 and the negative pressure tank 61 are communicated with each other via a communication passage 64. An opening/closing valve 65 for switching between communication of the through hole 63 and the negative pressure tank 61 by the communication passage 64 and blocking of the communication is provided in the middle of the communication passage 64.

The evacuation device 60 operates as follows. By the operation of the negative pressure pump 62, the inside of the negative pressure tank 61 has a negative pressure (pressure lower than atmospheric pressure). When the opening/closing valve 65 is opened, the through hole 63 and the negative pressure tank 61 are communicated with each other via the communication passage 64. Along with this, the gas in the space is sucked and extracted via the communication passage 64 and the through hole 63, and the amount of gas in the space is reduced to a low pressure state.

The hot press device 30 has a heating device 70 for heating the mold device 40. The heating device 70 is connected to the first steam passage 71 formed inside the mother die 45, the second steam passage 72 formed inside the nest 46, and the first and second steam passages 71 and 72. And a boiler 73. High-temperature steam is supplied from the boiler 73 to the first and second steam passages 71 and 72. The mother mold 45 and the insert 46 are heated by the high temperature steam passing through the insides of the first and second steam passages 71 and 72.

Hereinafter, the execution mode of the hot pressing by the hot pressing device 30 will be described together with the working effects.
As shown in FIG. 7, when forming the skeleton member 20, first, the steel plate 21 is set inside the mold device 40 (step S1). Specifically, the steel plate 21 press-formed in advance by a separate press device is prepared. Then, as shown in FIG. 8, the mold device 40 is set in the mold open state, and the steel plate 21 is placed on the fixed mold 41.

Next, the adhesive sheet 22A and the SMC 23A are set inside the mold device 40 (step S2 in FIG. 7). Specifically, as shown in FIG. 9, the adhesive sheet 22A and the SMC 23A are placed on the steel plate 21 so that the steel sheet 21, the adhesive sheet 22A, and the SMC 23A are arranged in this order from the lower side.

After that, the mold device 40 is clamped to a temporary clamping position before the position where the mold device 40 is in the mold clamping state (state shown in FIG. 5) (step S3 in FIG. 7). Specifically, as shown in FIG. 10, the seal member 48 on the inner surface of the annular wall 47 of the movable die 43 and the outer peripheral surface of the fixed die 41 are in contact with each other over the entire circumference, and The movable die 43 is moved downward to a position where the tip of the insert 46 does not contact the steel plate 21. As a result, a predetermined space SP2 is defined between the fixed die 41 and the movable die 43. Then, in this state, the step of sucking the gas in the space SP2 (so-called vacuum drawing) is executed by the vacuum drawing device 60. Specifically, the opening/closing valve 65 is opened for a predetermined time, and the negative pressure tank 61 is connected to the space SP2. As a result, the gas (air) in the space SP2 is evacuated to a low pressure state, so that the mold clamping of the mold device 40 thereafter can be smoothly performed.

Then, the mold device 40 is clamped to the intermediate position (step S4 in FIG. 7). Specifically, as shown in FIG. 1, the front end of the insert 46 is in a position where it abuts against the steel plate 21 and the end 22B of the adhesive sheet 22A, and the mother die 45 is in a mold clamped state (state shown in FIG. 5). The movable die 43 is moved downward to a position before the final position of (1). In the present embodiment, the step of moving the movable die 43 in this way corresponds to the sandwiching step.

Then, this state is held for a predetermined time (for example, several seconds). In the present embodiment, based on the results of various experiments and simulations performed by the inventor, a heating time that allows the end portion 22B of the adhesive sheet 22A to be cured to such an extent that the occurrence of burrs can be appropriately suppressed is obtained in advance. The same time is set as the predetermined time. Further, in the present embodiment, the step of maintaining the state where the tip of the insert 46 is in contact with the steel plate 21 and the end 22B of the adhesive sheet 22A for a predetermined time corresponds to the heating step.

As shown in FIG. 11, at this time, the end 22B of the adhesive sheet 22A is sandwiched between the tip of the insert 46 and the steel plate 21. The insert 46 is heated by the heating device 70. Therefore, at this time, the portion of the adhesive sheet 22A in contact with the nest 46, that is, the end portion 22B of the adhesive sheet 22A, is heated and hardened. At this time, the portion (inner portion) of the adhesive sheet 22A other than the end portion 22B is not in contact with the movable die 43 (the nest 46 and the mother die 45), and thus the movable die 43 is not heated and cured.

As described above, in the present embodiment, the end portion 22B of the adhesive sheet 22A is cured before the inner portion of the adhesive sheet 22A while being sandwiched between the nest 46 and the steel plate 21. As a result, the upper surface of the end portion 22B of the adhesive sheet 22A comes into close contact with the tip surface of the nest 46, and the lower surface of the end portion 22B of the adhesive sheet 22A comes into close contact with the upper surface of the steel plate 21. As described above, in the present embodiment, the gap between the insert 46 and the steel plate 21 can be filled with the end portion 22B of the adhesive sheet 22A that is cured between the insert 46 and the steel plate 21. In the present embodiment, the nest 46 corresponds to a heating unit that heats the end portion 22B of the adhesive sheet 22A so as to cure the end portion 22B before the inner portion of the adhesive sheet 22A.

Here, the dimensional accuracy of the press-formed steel plate 21 is likely to be lower than that of a resin molded product. Therefore, when the metal-resin composite is formed by the die device using the press-formed steel plate 21, a gap is likely to be formed between the mating surfaces of the steel plate 21 and the die, and burrs caused by the gap are generated. It can easily be said to occur. In this respect, in the present embodiment, the end portion 22B of the adhesive sheet 22A can be heated and cured in such a manner that the outer surface of the steel sheet 21 and the tip surface of the insert 46 are brought into close contact with each other. Accordingly, the space between the steel plate 21 and the nest 46 can be accurately filled with the end portion 22B of the adhesive sheet 22A, and thus the occurrence of burrs can be suppressed appropriately.

After that, the mold is clamped up to the position where the mold device 40 is in the mold clamped state (the final position shown in FIG. 5) (step S5 in FIG. 7). As a result, the skeleton member 20 is formed by hot pressing. Specifically, the adhesive sheet 22A is heat-cured to form the adhesive layer 22, and the SMC 23A is stretched and formed into a predetermined shape, and also heat-cured to form the fiber-reinforced resin layer 23. In this way, the skeleton member 20 as a metal-resin composite having the steel plate 21, the adhesive layer 22, and the fiber-reinforced resin layer 23 is formed.

In the present embodiment, the end portion 22B of the adhesive sheet 22A (adhesive layer 22) is sandwiched between the insert 46 and the steel plate 21, and is heat-cured before the inner portion of the adhesive sheet 22A. Then, during the subsequent hot pressing, the SMC 23A is stretched and formed into a predetermined shape. At this time, the SMC 23A can be prevented from flowing out of the space SP1 beyond the end portion 22B of the adhesive sheet 22A in such a manner that it is blocked by the end portion 22B of the cured adhesive sheet 22A. Therefore, it is possible to suppress the occurrence of burrs when the frame member 20 is formed by hot pressing.

In the skeleton member 20 of the present embodiment, since the end portion 22B of the adhesive sheet 22A is sandwiched between the tip of the insert 46 and the steel plate 21, the adhesive sheet 22A is heat-cured before the inner portion of the adhesive sheet 22A. It is unlikely that the thickness of each portion of the end portion 22B of 22A varies. On the other hand, in the inner portion of the adhesive sheet 22A, when the SMC 23A is stretched, the SMC 23A flows on the surface of the adhesive sheet 22A. The thickness of the (adhesive layer 22) varies.

Therefore, in the skeleton member 20 of the present embodiment, the boundary between the end portion 22B of the adhesive sheet 22A (adhesive layer 22) and the inner portion (the end portion on the inner peripheral side of the nest 46 in the mold device 40 and the mother die 45). A slight step is formed at the boundary). In the mold device 40, the end portion on the inner side (the right side in FIG. 6) of the end portion 22B of the adhesive sheet 22A and the region where the SMC 23A flows inside the mold device 40 (the upper surface of the adhesive sheet 22A and the mother die). The end of the area defined by the lower surface of 45). Then, the above-mentioned slight step is formed at this end (the portion indicated by the arrow C in FIG. 6). Moreover, in the skeleton member 20 of this embodiment, the degree of variation in the thickness of the adhesive layer 22 is different between the end portion 22B and the inner portion of the adhesive layer 22.

After that, the mold device 40 is opened and the skeleton member 20 is taken out of the mold device 40 (step S6 in FIG. 7).
In this way, the skeletal member 20 of the present embodiment is molded by hot pressing by the hot pressing device 30.

As described above, according to this embodiment, the following operational effects can be obtained.
(1) The end portion 22B of the adhesive sheet 22A is sandwiched between the insert 46 and the steel plate 21, and is heat-cured before the inner portion of the adhesive sheet 22A and the SMC 23A. Therefore, it is possible to suppress the occurrence of burrs when the frame member 20 is formed by hot pressing.

(2) The movable die 43 has a mother die 45 and a nesting 46 provided on the mother die 45 so as to be relatively movable in the die clamping direction. Then, the nesting 46 as a heating unit is located at a mold clamping position when the mold device 40 is in a mold clamping state before the mother mold 45 (specifically, the tip of the nesting 46 is the end of the adhesive sheet 22A). The position of contacting the portion 22B) is reached. Therefore, when molding the skeletal member 20 by hot pressing, first, the end portion 22B of the thermosetting adhesive sheet 22A can be heated and hardened by the nesting member 46. Then, since the mother die 45 comes to the mold clamping position (final position) after that, the mother die 45 molds the resin material (the adhesive sheet 22A and the SMC 23A) inside the end portion 22B of the adhesive sheet 22A and heats it. Can be cured.

The above embodiment may be modified and implemented as follows.
When forming the skeleton member 20, the movable mold 43 may be continuously moved from the mold open state to the mold clamp state without temporarily stopping the movement of the movable mold 43. With this configuration as well, the nest 46 is in the mold clamping position before the mother die 45 is in the mold clamping position. Therefore, the end portion 22B of the adhesive sheet 22A is the same as that in the state of being sandwiched between the nest 46 and the steel plate 21. It can be heat-cured before the inner portion of the adhesive sheet 22A and the SMC 23A.

The hot pressing device 30 and the method for molding the skeleton member 20 according to the above-described embodiment have a skeleton having a portion (non-forming portion) where the adhesive layer 22 and the fiber reinforced resin layer 23 are not provided in a mode in which a through hole is formed. It can also be applied to members. In the above configuration, a nest having the same structure as the nest 46, specifically, an annular shape extending along the inner edge of the non-formed portion of the skeleton member, can heat the entire end of the adhesive sheet 22A. It may be possible to provide a proper nesting. According to such a configuration, at the inner edge of the non-formed portion of the skeletal member, the end portion of the adhesive sheet 22A is sandwiched between the outer surface of the nest and the outer surface of the steel plate 21. Can also be heat-cured first. As a result, it is possible to suppress the occurrence of burrs at the inner edge of the non-formed portion of the skeleton member.

When the adhesive layer 22 and the fiber reinforced resin layer 23 are formed on the surface of the steel plate 21 on the fixed mold 41 side, the fixed mold 41 may be provided with a nest having the same structure as the nest 46.

As a configuration for heating the mother die 45 and the nest 46, instead of providing the boiler 73 and the first and second steam passages 71, 72, an oil passage for supplying high temperature oil to the inside of the movable die 43 is provided. It may be provided or an electric heater may be attached to the movable die 43.

The heating part for heating the end 22B of the adhesive sheet 22A may be provided integrally with the movable die 43 or the fixed die 41.
12 to 14 show an example of such a mold device 80. 12 to 14, the same components as those of the hot press device 30 illustrated in FIGS. 1 to 11 above are denoted by the same reference numerals or corresponding reference numerals, and the configurations are duplicated. The description is omitted.

As shown in FIGS. 12 to 14, both the heating portion 91 integrated with the fixed die 81 and the heating portion 92 integral with the movable die 83 are provided inside the base portion 93 and the base portion 93 formed of a metal material. And a heating wire 94 as a heating element. The heating section 92 integrated with the movable die 83 is fixed to the movable die 83 via a heat insulating layer 95 having a heat insulating function. The heating portion 92 has an annular shape extending along the end of the space SP1 (FIG. 14). The lower surface of the heating portion 92 has a step portion 84 having a shape in which the outer peripheral side projects toward the fixed mold 81 side rather than the inner peripheral side. When the lower surface of the heating portion 92 comes into contact with the steel plate 21 during the mold clamping of the mold device 80, a portion of the lower surface of the heating portion 92 on the inner peripheral side of the step portion 84 and the upper surface of the steel plate 21 is provided. A gap 52 is formed in the. Then, in the mold device 80, the end portion 22B of the adhesive sheet 22A is accommodated in the gap 52. The heating unit 91 integrated with the fixed die 81 is fixed to the fixed die 81 via a heat insulating layer 95 having a heat insulating function. The heating portion 91 has an annular shape that extends when the steel plate 21 and the end portion 22B of the adhesive sheet 22A are sandwiched between the heating portion 91 and the heating portion 92 when in the mold clamping state (state shown in FIG. 13). .. In the above-described configuration, by energizing the heating wire 94 of the heating unit 92, the temperature of the heating unit 92 becomes higher than the temperature of the portion of the movable die 83 other than the heating unit 92. Further, by energizing the heating wire 94 of the heating unit 91, the temperature of the heating unit 91 becomes higher than the temperature of the portion other than the heating unit 91 in the fixed die 81.

According to the above configuration, when the fixed die 81 and the movable die 83 are clamped during the molding of the skeleton member 20, the portion where the heating portions 91 and 92 are arranged, that is, the end portion 22B of the adhesive sheet 22A is disposed. The portion to be heated can be heated to a higher temperature than the peripheral portion. Accordingly, the end portion 22B of the adhesive sheet 22A can be cured before the resin material of the inner portion of the end portion 22B (specifically, the inner portion of the adhesive sheet 22A or the SMC 23A).

The heating unit 91 in the mold device 80 can be omitted. Further, when the adhesive layer 22 and the fiber reinforced resin layer 23 are formed on the surface of the steel plate 21 on the fixed die 81 side, the heating unit 92 may be omitted and only the heating unit 91 may be provided. Further, instead of the heating portions 91, 92 having the heating wire 94 provided in the base portion 93, a structure in which a steam passage for supplying steam is provided in the base portion 93, or the base portion 93 is provided. It is possible to have a structure in which an oil passage through which high temperature oil is supplied is provided.

The end portion 22B of the adhesive sheet 22A may be formed of a resin material (so-called quick-curing resin material) that cures faster than the resin material forming the inner portion of the adhesive sheet 22B. According to such a configuration, the end portion 22B of the adhesive sheet 22A can be cured early, so that the SMC 23A can be appropriately suppressed from flowing out beyond the end portion 22B of the adhesive sheet 22A.
