The utility model relates to the technical field of step induction, and disclose a kind of step induction mechanism for mould, including limiting mechanism and induction mechanism, the induction mechanism is located in the inside of limiting mechanism, the limiting mechanism includes fixed base, vertical shaft is rotatably connected in the inside of fixed base.The step induction mechanism for mould, with the advantages such as convenient dismounting, solve in mould production, step induction mechanism is important to control mould opening and closing, guarantee product quality.But existing mechanism has obvious defect: its structure is complex, many parts, rely on professional personnel and a variety of tools fine adjustment when assembling, time-consuming and labor-consuming;Operation is mainly automated, and it cannot meet the demand of artificial flexible adjustment in trial stage, leading to inefficient trial and high cost;When maintaining, a large number of associated parts need to be disassembled for replacing the wearing parts, which is not only troublesome but also easy to damage other components, and the
tail material cannot be taken out in time, which often causes the
production line to stop, seriously affecting the production progress and efficiency.
