Lower die gap cleaning device of powder dry-pressing molding equipment

The utility model provides a lower die gap cleaning device of powder dry-pressing forming equipment, and effectively solves the problems that in the prior art, a gap between a core rod and a lower dieis inconvenient to clean, the operation is tedious and the efficiency is low during cleaning. The technical scheme is as follows. Included is a vertical mandrel, a cylindrical lower die is sleeved onthe core rod; the left side and the right side of the core rod are respectively provided with a horizontal bottom plate which can only move leftwards and rightwards, semicircular notches are formed in the sides, close to each other, of the two bottom plates and can clamp the core rod, movable plates with the same size as the bottom plates are arranged on the upper sides of the bottom plates, an arc-shaped plate is arranged at the upper end of each movable plate, and the two arc-shaped plates get close to surround the core rod. Sliding grooves distributed in the left-right direction are formedin the sides, close to eac
