The invention discloses an easy-dismounting type two-step ejection mechanism, which belongs to the field of molds. The easy-dismounting type two-step ejection mechanism comprises a plastic compressor pulling rod arranged at the bottom part of a mold, an upper ejection plate connected with the plastic compressor pulling rod, a middle ejection plate and a lower ejection plate which are orderly arranged at one side of the upper ejection plate, a return pin arranged in the upper ejection plate through a spring, an ejection limiter arranged at the end part of the upper ejection plate, an ejection block arranged at the upper ejector plate through a screw, an ejector plate crossed through the bottom plate, the lower ejector plate, the middle ejector plate, the upper ejector plate and a mold foot, an ejection shaft arranged at the end part of the ejector plate, an ejection spring arranged in the middle of the ejection plate, a secondary ejection limiter arranged in a moving template of the mold, and an ejector rod crossed through the moving template, the mold foot, and the upper ejection plate; a clamping block of the ejector plate and the other clamping block of the ejector plate block adjacent to it are arranged on the ejector plate. Compared with the existed two-step ejection mechanism, the easy-dismounting type two-step ejection mechanism is less in parts, very simple in structure, low in manufacturing cost, short in processing and assembling cycles, and simple and easy to maintain.
