APPARATUS FOR MOLDING FOAM-RESIN COMPOSITE METAL PLATE

摘要

To provide an apparatus for molding a foam-resin composite metal plate, capable of enhancing filling characteristic of a foam resin in a simple structure and preventing the foam resin from leaking out between a steel material and a back-surface material.SOLUTION: An apparatus 100 for molding a foam-resin composite metal plate 20 includes: an upper mold 3 capable of coming into contact with a back-surface material 21; a lower mold 4 capable of coming into contact with a steel plate 22; and an air bag 6 applying pressure onto the upper mold 3 and the lower mold 4. The upper mold 3 is formed with at least one vent groove 31 and the inside of the vent groove 31 is provided with elastic members 9a and 9b. In a state in which the back-surface material 21 and the steel plate 22 are sandwiched between the upper mold 3 and the lower mold 4, the air in a foam resin filling space X can be flown out to the outside via the vent groove 31. In addition, between the elastic members 9a and 9b and the steel plate 22, there is provided a gap D where the back-surface material 21 can be lifted up and a foam resin H cannot leak out.SELECTED DRAWING: Figure 5
