Shoe mould clamp of digital control engraving and milling machine

The utility model provides a shoe mould clamp of a digital control engraving and milling machine, which comprises a clamp base, a shoe mould fixing mechanism, a rotation shaft and a positioning mechanism for the rotation angle of the rotation shaft of the shoe mould fixing mechanism. The positioning mechanism is provided with a first locking piece for positioning the rotation angle of the rotation shaft of the shoe mould fixing mechanism, and the first locking piece is inserted into the clamp base from a lateral surface of the clamp base. The locking piece of the rotation shaft of the shoe mould fixing mechanism is inserted between the clamp base and the rotation shaft through the lateral surface to position the shoe mould fixing mechanism, thereby avoiding clogging problem of positioning holes by impurities such as dust and the like, and precisely positioning the shoe mould fixing mechanism. The clamp base can adopt rotatable mode, and the scheme of the positioning mechanism is also adopted, thereby realizin
