[0003] However, the existing composite packaging box forming mold is mainly composed of fiberglass, and the upper and lower molds are connected by bolts to pre-tighten and pressurize the flange. However, because the size of the upper and lower mold forming tooling exceeds the conventional size, the upper and lower mold positioning is not accurate, and the production operation is inconvenient. As a result, the product quality is rough, and secondary machining is required to achieve the required flatness and roughness. This not only increases the cost of product development, but also puts higher technical requirements on manufacturing equipment.

[0004] The Chinese utility model patent "A fully automatic online packaging and flanging device" discloses that the flanging device includes a flanging unit and a material transfer unit, the material transfer unit moves back and forth between the packaging unit and the flanging unit, the flanging unit includes a flipping seat and a flanging assembly, the flanging assembly includes a flipping plate and a flipping plate flipping drive device, the flipping plate is located on one side of the flipping seat, and the flipping plate flipping drive device drives the flipping plate to flip upward toward the flipping seat.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some implementation examples of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-4 In the embodiment of the utility model, an auxiliary tooling for flanging a composite material packaging box for VIP molding includes a plurality of molding blocks 1, a plurality of limiting blocks 2, and a plurality of countersunk screws 3; the molding blocks 1 are provided with threaded holes, the limiting blocks 2 are provided with countersunk holes, and the molding blocks 1 and the limiting blocks 2 are connected and fixed by countersunk screws 3. In this way, the plurality of molding blocks 1 are spliced ​​into a frame, which is installed at the place where the cavity of the composite material packaging box 5 needs to be flanging, and a plurality of limiting blocks 2 are arranged along one side of the lower part of the frame, the inner side of the limiting blocks 2 is parallel to the inner side of the frame formed by the molding blocks 1, and the outer side of the limiting blocks 2 is convex.

[0021] The forming block 1 of the utility model can be made of metal materials such as aluminum alloy and structural steel.

[0022] The limit block 2 of the present invention can be made of metal materials such as aluminum alloy and structural steel.

[0023] The mold 4 of the utility model can be a composite material, a steel mold, or a wooden mold. The mold 4 has sufficient rigidity and good air tightness, and fits the surface of the composite material packaging box 5. During the curing process of the composite material packaging box 5, the mold 4 provides a stable curing environment to ensure that the composite material packaging box 5 does not deform during the curing process.

[0024] When the utility model is used, a frame formed by splicing a plurality of forming blocks 1 is pressed onto a mold 4, the limit block 2 is in contact with the mold 4, and the upper part of the forming blocks 1 is placed on the flange in sequence. Under the VIP process, the utility model and the composite material packaging box 5 are subjected to a downward pressure under the action of atmospheric pressure, and the flange will be attached to the composite material packaging box 5 under the atmospheric pressure of the utility model and the side, and the mold 4 provides a rigid support and a closed environment during the curing process of the composite material packaging box 5. The overlapping part of the limit block 2 on the composite material packaging box forming mold will limit the downward movement of the entire tooling, so that the height of the flange of the VIP-molded composite material packaging box must be precisely controlled. The material forming the flange of the utility model is the same as the material used for the main body of the composite material box.

[0025] The utility model realizes the molding of the flange of the composite material packaging box by screw fastening, and the operation is simple and reliable, the tooling processing cycle is short, the tooling processing equipment stroke requirement is low, and the tooling molding surface roughness is low. It can be applied to VIP molding tooling, and provides a reliable tooling form for the flange molding of large-size composite material packaging boxes.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in the embodiments may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0027] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims themselves.
