[Industrial applications]

 The present invention relates to a thermosetting resin laminated material manufacturing apparatus, and more particularly to a thermosetting resin laminated material manufacturing apparatus used for wall panels such as architectural glass panels.

[0002]

[Prior art]

 Conventionally, a thermosetting resin laminated mold material 52 used as a mold for a plate-shaped member 51 such as a glass panel shown in FIG. 6 is formed by continuously extruding an aluminum-made mold material 53 on an aluminum smelting plant, Unrolled thermosetting silicone rubber 54, which is obtained by slitting it into a sheet with a specified thickness using two rolls and then slitting it into a specified width, heats and vulcanizes it with a hot press or oven. However, it has been manufactured by integrating both.

[0003]

[Problems to be solved by the device]

 However, since this method uses unvulcanized thermosetting silicone rubber 54 obtained by roll work, it has limitations in its length and width dimensions and cannot be applied to all long products required in the market. It was In addition, a special jig is required for heating and vulcanizing in a hot press or an oven, and an unvulcanized thermosetting silicone rubber 54 is attached to the surface of the aluminum mold material 53 with uniform force over the entire surface. It was difficult to press, and as a result, the dimensional accuracy after vulcanization was poor and the surface became uneven. Therefore, the object of the present invention is to provide a device for manufacturing a thermosetting resin laminated mold material which can be applied to a long product of any size required in the market and has improved dimensional accuracy after heating and vulcanization. To do.

[0007]

[Action]

Thermosetting resins 10, 30 such as unvulcanized thermosetting silicone rubber, various synthetic rubbers, and synthetic resin foam materials move while being kneaded by the screws (not shown) of the extruders 18, 38, and from above It is sent to the supply passages 14 and 34 of the bases 13 and 33. At this time, the thermosetting resin is introduced at a high pressure of 700 to 1,000 kgf / cm ² , and the mold members 4 and 24 receive a pressing force of about 1 ton. On the other hand, the moving force of the automatic feeders 16 and 36 in the horizontal direction of the mold members 4 and 24 cannot be largely given in terms of the shape and strength of the mold members, and is about 5 to 10 kgf. For this reason, it is desirable to reduce the running resistance between the mold members 4 and 24 and the running rail bases 2 and 22 in the transfer passages 3 and 23 as much as possible. As a result of various experiments by the present inventors, in the extrusion dies shown in FIGS. 1 to 3, the traveling rail base 2 is made of a fluororesin having a sliding friction resistance of about 0.05 to 0.1, and in the extrusion dies shown in FIGS. If the table 22 is a roller bearing guide roller type with a rolling friction coefficient of about 0.01 to 0.005, it can withstand a pressing force due to a high internal pressure, and as a result, a horizontal movement force of about 5 to 10 kgf can be applied to the shape member 4 , 24 can be smoothly driven at a constant speed. In these extrusion dies, the thickness of the thermosetting resin layers 7 and 27 such as various synthetic rubbers and synthetic resin foams on the mold members 4 and 24 can be changed by changing the thickness of the side plates 6 and 26 and the die lips 15 and 35. It can be easily handled by exchanging.

The supply passages 11, 14, 31, 34 for the thermosetting resins 10, 30 may be inclined by 0 to 70 ° with respect to the normal direction of the transfer passages 3, 23 for the mold members 4, 24. , 24 can be given a moving component in the horizontal direction, which reduces the horizontal moving force of the automatic feeders 16, 36. When the size of the extrusion die is, for example, length: 100 mm, width: 120 mm, height: 180 mm, the weight is about 8 kgf, and it can be made very compact. Since the mold members 4 and 24 are lightweight and strong because they are construction members, those made of aluminum alloy are preferable. In addition to the shape shown in the figure, any cross-sectional shape can be adopted. In that case, it is possible to deal with it by changing the mold material guides 5, 25. The thermosetting resin laminated mold material pressed and integrated by the manufacturing apparatus of the present invention is directly moved to a drying oven (or a vulcanizing oven, neither of which is shown) for vulcanization. As a result, a uniform thermosetting resin laminated mold material having stable dimensional accuracy can be continuously obtained in an arbitrary length. It should be noted that the surfaces of the mold members 4 and 24 are preferably subjected to a primer treatment in advance in order to strengthen and securely bond and integrate the thermosetting resin and the mold member.

【Example】

 In the apparatus for manufacturing thermosetting resin laminated mold materials shown in FIGS. 1 to 3 and 4 to 5, the extruder has a screw diameter of 50 mm and a screw rotation speed of 80 rpm, and a mold material automatic supply device has a supply speed: 1,500 mm / min, made of aluminum alloy as a mold material and having a cross-sectional shape shown in Fig. 6 with a total length of 2,000 mm, unvulcanized thermosetting silicone rubber as a thermosetting resin, and the running rail of the mold material of Fig. 1. Extrusion molding of the laminated mold material was performed by using fluororesin-made bases. The laminated material was smooth and stable. After vulcanization was performed in a drying oven with a furnace length of about 220 ° C and a total length of 5 m, the dimensions were measured and found to be stable with a width of 19 ± 0.3 mm and a height of 10 ± 0.2 mm. The surface condition of the subsequent thermosetting silicone rubber was good.

[Effect of device]

 In the thermosetting resin laminated mold material manufacturing apparatus of the present invention, a uniform product can be produced by pressing and integrating the mold material and the thermosetting resin in the apparatus. Further, since the continuous extrusion is performed, it is possible to obtain a long mold material having an arbitrary length.
