METHOD AND DEVICE FOR MANUFACTURING BUSH OF DOUBLE-LAYER STRUCTRURE

摘要

A method for manufacturing a bush of double-layer structure capable of efficiently manufacturing the bush (A) of double-layer structure used for a stabilizer bush, comprising the steps of forming a cavity (C1) for outer rubber by a drag (8) having a mold hole (81) and a first cope (10) having a core pin (11) in a first forming stage (1) to form an outer layer rubber (A1), feeding the drag (8) having the formed outer layer rubber (A1) to a second forming stage (2), forming a cavity (C2) for inner layer rubber by the drag (8) and a second cope (20) having a core pin (21) to form an inner layer rubber (A2), feeding the drag (8) to a releasing stage (3), releasing and taking out a mold product, returning the drag (8) to the first forming stage (1), and repeating these steps above.
