Split type mouth-shaped plate

A split type mouth-shaped plate relates to the technical field of tire manufacturing, and comprises a front mouth-shaped plate and a rear mouth-shaped plate, the front mouth-shaped plate adopts a steel plate with the thickness of 8mm, the rear mouth-shaped plate adopts a steel plate with the thickness of 15mm, a rectangular glue flowing port is formed in the middle of the front mouth-shaped plate, the rear mouth-shaped plate comprises an upper plate and a lower plate connected with the upper plate, and the upper plate and the lower plate are connected with each other. The bottom of the upper plate is provided with a glue outlet, and the glue outlet is symmetrically arranged about the longitudinal center line of the mouth-shaped plate. The mouth-shaped plate can reduce the extrusion pressure of a part and solve the problem of scorching of the part, and is realized by a method of adjusting the thickness of a mouth-shaped outlet; the die can be used for producing cushion rubber, tire sidewalls, apex and small-sp
