MANUFACTURING DEVICE FOR BOOT FOR CONSTANT VELOCITY JOINT, AND MANUFACTURING METHOD FOR BOOT FOR CONSTANT VELOCITY JOINT

摘要

This manufacturing device for a boot (9) for a constant velocity joint is provided with a molding die (1) for injection molding a molded body (W) using: an inner die (12) configured by radially arranging split dies (15a-15h) along the outer peripheral surface (14a) of a vertically extending core shaft (14); and an outer die (11). The manufacturing device is also provided with bar-like support members (23a-23h) having: front end sections (232a-232h) which are inserted into recesses (154a-154h) formed in the extended sections (155a-155h) of the split dies (15a-15h), thereby being capable of supporting the split dies (15a-15h); and stepped surfaces (234a-234h) which are in contact with the outer peripheral surfaces of the extended sections (155a-155h) while the split dies (15a-15h) are supported by the front end sections (232a-232h).
