Embodiment Construction

[0029] The application will be further described in detail below through specific embodiments in conjunction with the drawings. In the text, "front", "rear", "left", "right", "up" and "down" are all based on the placement state of the mold in the drawings.

[0030] When the existing mold is bending and forming the aluminum sheet metal 5 of gradual thickness, since the upper mold 1 and the lower mold 2 are in vertical relative motion, the forces of the two against the aluminum sheet metal 5 are relatively concentrated. In the vertical direction, it is unable to provide sufficient force in the bending direction to bend the aluminum sheet metal 5, so the existing mold has a large springback when bending the aluminum sheet metal 5 It cannot be overcome, resulting in that the bent aluminum sheet metal 5 cannot meet the requirements of the bending angle. In order to overcome the rebound and adjust the bending angle in place, the existing forming process will adjust the aluminum sheet m...

Abstract

The invention relates to a mold which comprises an upper mold and a lower mold.The upper mold comprises an upper mold base body, a molding male mold and a molding limiting male mold, the molding male mold and the molding limiting male mold are both fixed on the upper mold base body and protrude out of the bottom of the upper mold base body, the molding male mold has a first main plane and a molding surface, the molding limiting male mold has a second main plane and two limiting surfaces, the molding male mold and the molding limiting male mold are arranged to be adjacent to each other, and the first main plane is opposite to and parallel to the second main plane; the lower mold comprises a lower mold base body, a molding material pressing block, a sliding molding female mold and an elastic mechanism, the sliding molding female mold is arranged on the lower mold base body, the side, facing the molding material pressing block, of the sliding molding female mold has a matching surface matched with the limiting surfaces, the elastic mechanism is arranged at the end, far away from the molding material pressing block, of the sliding molding female mold and fixedly connected with the lower mold base body, and a containing gap of which the size is matched with that of a molding material is reserved between the molding surface and the matching surface.

Description

Technical field [0001] This application relates to a mold, in particular to a mold capable of reducing the appearance defect rate of aluminum sheet metal. Background technique [0002] For the bending and forming of aluminum sheet metal with gradual thickness, the existing method is mainly to use a mold to bend it. Due to the inconsistent thickness of aluminum sheet metal with gradual thickness, the existing mold cannot completely press the aluminum sheet metal In order to overcome this problem, the prior art also adjusts the rebound of the bending angle through bending and shaping. However, due to the softness of the aluminum sheet metal and the shaping process The stress of the aluminum sheet metal is inconsistent, and the plastic work can easily cause the aluminum sheet metal at the bend to be deformed and surface scratches, thereby increasing the appearance defect rate of the aluminum sheet metal, and leading to the production cost. increase. Summary of the invention [0003...
