Abstract
Described herein is a mold. The mold includes a first mold half and a second mold half. A molding cavity is definable between the first mold half and the second mold half within which a molded article is moldable. The mold also includes a core configured to form a seal on the molded article. The first mold half and the second mold half are configured to remain in a mold closed configuration with molding and stripping of the molded article.
Claims14
A mold comprising:
- a first mold half and a second mold half, the first and second mold halves being selectively movable relative to each other between a mold open configuration and a mold closed configuration;
- a molding cavity cooperating with at least in one of the first and second mold halves;
- and
- a core selectively positionable within the molding cavity, the molding cavity and the core cooperating to form a molded article upon injection of suitable material into the molding cavity, the core including a radial feature on an outer surface thereof configured to form a corresponding feature on an inner surface of the molded article, the feature on the core engagable with the feature on the molded article upon removal of the molded article from the molding cavity;
- wherein the first mold half and the second mold half are configured to remain in a mold closed configuration during both a) molding of the molded article in the molding cavity and b) subsequent removal of the molded article from the molding cavity.
