Numerical control engraving and milling machine for mold production

The utility model relates to the technical field of mold production, and discloses a numerical control engraving and milling machine for mold production, which comprises a bottom plate, two support legs are arranged on each of the left side and the right side of the bottom of the bottom plate, a U-shaped frame is arranged at the top of the bottom plate, and a moving component is arranged on the inner top wall of the U-shaped frame. According to the numerical control engraving and milling machine for mold production, a to-be-machined mold is placed on the top of a bottom plate and located between two L-shaped rods, then a second hydraulic cylinder is started to drive a transverse plate to move upwards, so that a pulley extrudes wedge-shaped blocks, then the two wedge-shaped blocks are driven to compress reset springs to move relatively, and therefore the two L-shaped rods are driven to move relatively; according to the fixing device for the die to be machined, the screw rod is driven to rotate through the hand
