Abstract

Un aparato de moldeo puede incluir un molde principal, un desmoldeador y un miembro oscilante. El miembro oscilante puede comprender una superficie de moldear que define una porción de muesca de guía de un artículo moldeado. El miembro oscilante puede hacer contacto directamente con el desmoldeador y el molde principal o bien, estar fijado a éstos. Para poder retirar fácilmente un artículo moldeado, el miembro oscilante puede retirarse a través de un orificio en el molde principal como resultado directo del movimiento del desmoldeador para sacar el artículo moldeado del molde principal. Posteriormente, el artículo moldeado puede retirarse con facilidad.
