MOLDING METHOD, MOLDING MOLD, AND PLUNGER

摘要

PROBLEM TO BE SOLVED: To provide a molding method which can prevent the dragging and crush of a primary molding when a molding is produced by using a two-color molding method and a molding mold for the method. SOLUTION: A cavity 223c for secondary molding is formed in front of the injection gate 223a of a secondary mold part 223. An elastic gasket 320 to be fitted to a plunger shaft 310 molded in primary molding constitution is molded by the cavity 223c. The inner surface of the cavity 223c is separated from the entire surface part of the primary molding (the plunger shaft 310) exposed from a common mold structure part.
