The claim protected by the patent technology is "comprising a support column, the top of the support column is fixedly connected to a support plate, and the top of the support plate is fixedly connected to a connecting column. The utility model provides a mold manufacturing punching device which is provided with a rotating motor. When it is necessary to drill holes in the mold, the sliding block is moved horizontally, so that the sliding block can drive the rotating motor to move horizontally, that is, drive the drill bit to move horizontally, so as to adjust the drilling positions of the two drill bits. At this time, the two rotating motors are started and the lifting sleeve is moved downward, so that the lifting sleeve can drive the two drill bits to punch holes in the mold box through the two rotating motors, thereby avoiding the need to frequently adjust the fixed position of the mold when a single mold has a large number of holes to be punched, which in turn causes a lot of time to be spent on drilling holes in the mold, thereby improving the drilling efficiency of the punching device."
