  • Patent number: 11707878
    Abstract: A resin molding system 1 comprises a gripping device 3 provided with a gripping frame 30 for gripping a resin sheet material 2, a heating device for heating the resin sheet material 2 and a molding device for clamping a lower die 61 and an upper die, and affixing the resin sheet material 2 to a substrate 63. The molding device is provided with: a lowering device for lowering the gripping device 3 and causing the resin sheet material 2 gripped by the gripping frame 30 to approach the lower die 61; and a pair of bent posts 67, 68 which are provided on both Y-direction sides of the lower die 61, and which come in contact with portions of the gripping frame 30 when the gripping device 3 is lowered, and which convexly bend the gripping frame 30 upward as viewed from the side along the Y-direction.

  • Publication number: 20210245417
    Abstract: A stretching and bending mechanism 3, fixes a resin sheet material 2 by a first fixed clamp and a second fixed clamp at both sides of a center of a transverse direction of the resin sheet material 2 at each end in a longitudinal direction of the resin sheet material 2, and when transverse guides 13 are bent between the first and second fixed clamps 9a, 9b, at least one of the longitudinal guides 15 is guided by the bending guide 16 so as to move toward the center side in the transverse direction.

  • Publication number: 20190084213
    Abstract: A resin sheet material 2 in a state of being stretched in a longitudinal direction is held by a stretching and bending mechanism 3, and heated and softened by a heating unit 5. The softened resin sheet material 2 is stretched by pulling the ends in the longitudinal direction and ends in a transverse direction of the resin sheet material by the stretching and bending mechanism 3. The stretched resin sheet material 2 is bent by the stretching and bending mechanism 3, and molded by vacuum forming by a resin molding unit 6.
