ABSTRACT:
A method and apparatus for separating an injection molded product from a sprue/runner formed with the injection molded product in injection molds includes a product receiver underlying the injection molds for receiving the product after the molds have been opened and a sprue/runner receiver underlying the injection molds for receiving the sprue/runners after the molds have been opened. The product receiver and the sprue/runner receiver are positioned relative to the molds and relative to each other such that the product falls onto the product receiver while being precluded from falling into the sprue/runner receiver and the sprue/runners fall into the sprue/runner receiver while being precluded from falling onto the product receiver.
