Method of injection molding an article of footwear with a flashing circuit capsule in the heel thereof

摘要

A method of injection molding an article of footwear having a sole and an upper with the sole having a ball section and heel section, the heel section having a circuit capsule encapsulated therein. The circuit capsule is provided with LEDs to generate light beams through the heel of the article of footwear. The method comprises injection molding the sole with a peripheral upwardly extending side wall and then positioning an upper support mold with a sock upper at a predetermined position relative to the sole molded on a female mold. A hot liquid molding material is injected in a vamp forming cavity formed between the female mold and the upper support mold as well as in a capsule sealing cavity formed between a bottom wall of the upper support mold and the heel section of the sole whereby to interconnect the sole and the upper and simultaneously seal the circuit capsule in a capsule locating cavity within the heel portion of the sole.
