Abstract

The utility model discloses a U-shaped bender mold and belongs to the field of bender molds. The U-shaped bender mold comprises an upper mold, a lower mold, active blocks and a bottom-holding mold. A downward bending groove is disposed on an upper surface of the lower mold, and a first groove is disposed at the bottom of the bending groove. The active blocks are two in number and are respectively arranged on two side walls of the bending groove. A lower portion of the bottom-holding mold is inserted into the first groove, and a width of an upper half portion of the bottom-holding mold is larger than that of a lower half portion of the bottom-holding mold. A spring disposed inside the first groove enables the bottom-holding mold to move vertically along the first groove. Straight-line distances between two bosses of the two active blocks can be adjusted based on elasticity of different materials, a workpiece is turned into a U shape after being sprung back in the process of bending, and therefore the U-shaped bender mold is time-saving and labor-saving, and free of a secondary processing process. In addition, the U-shaped bender mold has the advantages of being simple in structure, reasonable in design and easy to fabricate.
