Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a clamping device for precision mold processing. Background Art

[0002] There are many ways to process molds, usually turning, milling, grinding and other processing methods, but the above steps all require the use of a clamping device to clamp the mold.

[0003] The clamping of the mold by the existing clamping device will affect the processing of the mold surface, and the angle of the mold cannot be adjusted. For example, the clamping device for precision mold processing disclosed in Chinese Patent Publication No. "CN215433341U" uses a screw and a clamping plate to clamp the mold, and a pressure plate is used to press the mold. However, the device cannot adjust the angle of the mold, which makes the device inconvenient for partial flat processing when in use. In addition, the arrangement of the pressure plate and the clamping plate causes the pressure plate and the clamping plate to block part of the mold surface when the device is in use, making the blocked surface of the mold unable to be processed. Accordingly, the present application proposes a clamping device for precision mold processing. Utility Model Content
