METHOD AND DEVICE FOR MANUFACTURING BUSH OF DOUBLE-LAYER STRUCTURE

摘要

The invention is to efficiently manufacture a double-layer structured bushing (A) used for a stabilizer bushing, etc. To that end, an outer layer rubber (A1) is molded by forming cavities (C1) for it by a lower mold (8) having mold holes (81) and a first upper mold (10) having core pins (11) at a first molding station (1), then the lower mold (8) including the outer layer rubber (A1) as molded is transferred to a second molding station (2) where an inner layer rubber (A2) is molded in cavities (C2) for it formed by the lower mold (8) and a second upper mold (20) having core pins (21), subsequently the lower mold (8) is transferred to a demolding station (3) to demold and remove the molded products, and thereafter the lower mold (8) is restored to the first molding station (1). Thus the steps are repeated.
