Apparatus for ejecting molded article

Abstract

A mold for forming an article such as a unitary sole and heel tread member of a shoe, and means integral with said mold for separating said article from such mold. The mold for such article is formed of first and second mold members defining a molding cavity therein, where one of said mold members is provided with an ejector pin projecting into said molding cavity to grip the article after forming. When the mold members are operatively assembled together for molding, where one of said mold members has been provided with conduit means for supplying casting material under pressure to said molding cavity, injection of the casting material through such conduit means to fill the molding cavity will result in the casting material flowing about said ejector pin. Such ejector pin is provided with a head or end configuration which is capable of gripping the molded article to pull or peel such member from one of the mold members, when such mold members are disassembled. While the casting material is molded about the head or end of the ejector pin, the end is designed so as to pull the molded article from the mold member, and at the same time not tear or damage the molded article. Similarly, an ejector pin may be employed to lift and remove the runner or sprue from the fixed or stationary mold member.
