The invention relates to drilling equipment, in particular to drilling equipment of a plastic suction die, which aims at solving the technical problem to provide drilling equipment of a plastic suction die, with capability of uniform drilling on a gypsum die. To solve the technical problem, the drilling equipment of the plastic suction die comprises a bottom plate, a left frame, a first bracket, a bearing block, a second bracket, a right frame, a first rotary shaft, a gear, a first spring, a first gear rack, a first guide sleeve, a second guide sleeve and the like, wherein the left frame and the first bracket are welded at the left side of the top part of the bottom plate; the left frame is positioned at the left side of the first bracket; the second bracket and the right frame are welded at the right side of the top part of the bottom plate; the right frame is positioned at the right side of the second bracket. The drilling equipment has the advantages that the uniform drilling effect is realized by the uniform-speed rotation of a cam and a fixing device; by specially adding a slide rail and a slide block on the device, the descending of a twist drill is stabilized, so that the easiness in deviation of drilling is avoided.
