摘要： A mold tool generally includes a base, a die assembly, a tightening element, a threaded element, and at least one shaping cap. The base defines a cutout, a first threaded hole opposite to the cutout, and a second threaded hole. The die assembly, composed of a first module and a second module, can be inserted into a receiving space of the base. The tightening element can be screwed into the second threaded hole of the base to fix the die assembly in place. The threaded element can be screwed into the first threaded hole of the base. The shaping cap can be fitted at one end of the threaded element. The die assembly defines channels of various diameters each for holding a tube of a specific diameter. The shaping cap can urge one end of a tube held in the die assembly to form a specific type of flare.
