Positioning device for mold production and processing machine tool

The utility model relates to the technical field of mold positioning and processing, in particular to a positioning device for a mold production and processing machine tool, which fixes the position of a mold through a clamping device and reduces scratches on the surface of the mold. Through the rotating device, conversion of mold machining faces is facilitated, and the machining efficiency of the device is improved; a water spraying device is used for assisting in spraying water in the mold machining process, surface chippings are washed away, and the temperature of a machined surface is lowered; metal chippings generated in the machining process are collected through the collecting device, and the labor intensity of operators for cleaning the surface of the device subsequently is reduced; the pressure of the clamping device is monitored through the protection device, mold deformation caused by too large pressure is prevented, and harm to operators caused by metal flying chips generated in the machining proc
