[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a clamping device for mold manufacturing, including a base 1, a mounting plate 12 is fixedly installed on the top of the base 1, fixed plates 3 are fixed on both sides of the mounting plate 12, a hydraulic cylinder 2 is fixed on one side of each group of fixed plates 3, and a connecting plate 4 and a central plate 8 are fixed to the output end of the hydraulic cylinder 2 in sequence. When the hydraulic cylinder 2 is started, it pushes the fixed plate 3 and the central plate 8 to move.

[0022] Sub-plates 5 are arranged on both sides of the central plate 8, and a cylinder 7 is arranged between the sub-plate 5 and the connecting plate 4. The cylinder 7 is fixed on the connecting plate 4, and the output end of the cylinder 7 is fixed to the sub-plate 5. Grooves 9 are opened on both sides of the central plate 8, and the sub-plate 5 is arranged inside the groove 9. The upper and lower bearings of the groove 9 are connected with a rotating shaft 10, and the rotating shaft 10 is fixedly connected to the sub-plate 5. Starting the cylinder 7 pushes the sub-plate 5 to rotate around the rotating shaft 10.

[0023] A plurality of friction strips 6 are fixed on the connecting plate 4 and the central plate 8. When the connecting plate 4 and the central plate 8 are in contact with the mold, the friction strips 6 increase the clamping stability.

[0024] The connecting plate 4 and the central plate 8 are both made of flexible materials.

[0025] The base 1 is provided with a plurality of mounting holes 11 for facilitating mounting the base 1 on a workbench.

[0026] A gap is left between the connecting plate 4 and the fixing plate 3 .

[0027] Working principle:

[0028] Place the mold on the mounting plate 12, start the hydraulic cylinder 2 to push the connecting plate 4 and the central plate 8 close to the mold, so that the central plate 8 contacts the mold. When the central plate 8 contacts the mold, the cylinder 7 moves along with the connecting plate 4 when it moves.

[0029] When the central plate 8 contacts the mold, the cylinder 7 is started to extend, driving the auxiliary plate 5 to rotate around the rotating shaft 10 so that the auxiliary plate 5 contacts the mold. Since the connecting plate 4 and the central plate 8 are both made of flexible materials, they can better fit the mold surface.

[0030] Furthermore, when encountering an irregularly shaped mold, the telescopic length of the cylinders 7 on both sides can be adjusted at will according to the shape of the mold to make the sub-plate 5 fit the mold surface, thereby improving the flexibility of clamping the mold.
