The tongue mould is cut in the grass mower tooth box plate punching of the utility model; Comprise that die, drift and front end have the punch of cutting the tongue cutting edge; Said punch is the corresponding setting in position that two and grass mower tooth box plate need be cut tongue; Cut tongue cutting edge and the tooth box plate of said punch are cut the ligulate shape and are fitted shape, and the die cavity cross section of die and tooth box plate are cut the right shape of ligulate shape; Said drift needs the corresponding setting of punching position, the corresponding drift cushion hole that is provided with drift of said die with grass mower tooth box plate.

Further, also comprise stripper plate, said stripper plate is provided with respectively the corresponding material demoulding hole that is coated at punch and drift, and said punch and the drift correspondence that is slidingly matched is passed separately material demoulding hole and die cavity and drift cushion hole corresponding matching;

Further, it is nested nested with the drift cushion hole to be embedded in die at die, and said die cavity is nested to form by die, and the drift cushion hole is nested to form by the drift cushion hole; Said punch is fixedly set in punch retainer, and said drift is fixedly set in punch retainer;

Further, it is nested that said punch retainer is fixed with punch, and it is nested that said punch fixedly is embedded in punch;

Further, be provided with cushion between said stripper plate and the punch retainer;

Further, also comprise top base and bottom base, said die is fixedly set in bottom base, and punch retainer is fixedly set in top base.

The beneficial effect of the utility model is: the tongue mould is cut in the grass mower tooth box plate punching of the utility model, adopts to have the cutter structure that the punch of cutting the tongue cutting edge and die are combined to form, and drift is set; Directly cooperate through punch and die after the feeding and cut away and cut tongue, drift is promptly accomplished the punching operation, can disposablely cut tongue and be shaped and punching; Has unified standard; Do not need following process, make working environment avoid noise and dust pollution, it is low to have a difficulty of processing; The characteristics of high efficiency, thus cut down finished cost.
