[0018] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0019] Example 1

[0020] like Figure 1 As shown, a tensioning mechanism for a mold hanging device of the utility model is composed of two outer frames 1, two inner frames 2 and a tensioning mechanism.

[0021] The outer frame 1 and the inner frame 2 both include an upper crossbeam, a middle crossbeam and a lower crossbeam. The upper crossbeam and the middle crossbeam of the inner frame 2 are respectively provided with slide grooves 3, and the tensioning mechanism is provided in the two slide grooves 3. The two inner frames 2 are connected together, and the two outer frames 1 are respectively distributed on the outsides of the two inner frames 2.

[0022] When the inner frame 2 of the mold hanging device is fixed and the outer frame 1 moves forward, the tensioning mechanism can freely move from the rear end of the slide groove 3 to the front end; when the outer frame 1 is fixed and the inner frame 2 moves forward, the tensioning mechanism can freely move from the front end of the slide groove 3 to the rear end; this reciprocating process can ensure that the outer frame 1 and the inner frame 2 are always connected together without affecting the movement of the device.

[0023] When the outer frame 1 and the inner frame 2 of the mold hanging device are skewed relative to each other, the tensioning mechanism can be operated to readjust the distance between the outer frame 1 and the inner frame 2.
