Holder for arranging a foil on a mold surface of a sidewall shell of a vulcanizing mold and a vulcanizing mold having such a holder

A vulcanizing mold comprising:

• a sidewall shell having a mold surface;
• a holder configured to arrange a foil on said mold surface of said sidewall shell of the vulcanizing mold;
• said holder being disposed in said sidewall shell;
• said holder having a cylindrical sleeve configured to be pressed into a bore in the sidewall shell;
• a helical spring;
• said holder further having a helically-spring-mounted, coaxially movable pin arranged in said sleeve;
• said cylindrical sleeve having a first sleeve end;
• said pin having a first pin end;
• said pin having, on said first pin end, a cylindrically formed pin head which, in an initial position, projects beyond said first sleeve end with a force of said helical spring and on which the foil can, via a corresponding punched-out portion, be positioned on said mold surface of said sidewall shell;
• said pin head having a first pin head end remote from said pin;
• said pin, in an end position, being configured to be movable into said cylindrical sleeve counter to the force of said helical spring such that said first pin head end is aligned with said first sleeve end;
• said pin head, with a pin head region facing toward the pin and in its initial position, being configured to form a clearance fit with said sleeve;
• and,
• said clearance fit between said pin head and said sleeve being selected such that said pin is movable in said sleeve but no rubber material can ingress into said sleeve between said pin head and said sleeve.
