EJECTION METHOD AND MOLD WITH EJECTION PIN

摘要

PROBLEM TO BE SOLVED: To provide an ejection method for preventing such a phenomenon that molding failure such as whitening or plucking is generated in a molded article when unreasonable force is applied to the molded article at the time of ejection by an ejection pin. SOLUTION: The screw 18 of the projection pin 8 formed to the leading end thereof is integrally molded within the molded article 24 at the time of molding. After molding, the molded article 24 is ejected from a mold by the ejection pin 8 and the ejection pin 8 is rotated to separate the ejection pin 8 and the molded article 24.
